Description

Skin management device

Technical Field

The present invention relates to a skin management device, and more particularly, to a skin management device in which one or two electrode systems can be implemented by one membrane, thereby improving user convenience, a skin management device in which a ground electrode can be connected by using a user's ear, a skin management device in which a ground can be implemented by using a user's hand holding a terminal, or a skin management device in which a current carrying area can be visually displayed.

Background

Generally, devices using electrical stimulation are widely used in the medical field of nerve regeneration, pain relief, rehabilitation, and the like. Further, electrical stimulation is also actively used in the cosmetic field.

As an example, recently, devices have been developed and sold that deliver low frequencies to the skin to improve the blood circulation of the skin and remove wrinkles. Such a device is composed of a power source and a membrane, and the skin beauty is embodied by receiving an electric stimulus applied from the power source and supplying the electric stimulus to the skin by the membrane.

In recent years, devices have been developed which provide good absorption of cosmetics and the like into the skin by electrical stimulation, in addition to simple application of electrical stimulation. In this case, the film sheet may be used by being dipped in a cosmetic.

In such a conventional technique, since a separate power supply is provided, a user places the power supply on the ground or a desk and attaches a membrane to a portion requiring electrical stimulation to use the membrane, but when a cable connecting the power supply and the membrane is short, the user needs to pick up the power supply and move the cable, which causes inconvenience, and when the cable connecting the power supply and the membrane is long, the user may twist the cable, which may deteriorate convenience.

That is, in the conventional case, since a separate power supply is required to represent the electrical stimulation, portability is reduced and improvement of the use satisfaction is limited.

Therefore, in recent years, a technology has been developed in which a terminal such as a smartphone, which is convenient for a user to carry, is used as a power source. When a cable connected to the membrane is connected to an earphone jack or the like of the smartphone, power is supplied from the smartphone to the membrane, whereby the membrane applies an electrical stimulus to the skin.

However, the technologies developed in this way are merely smart phones instead of power sources, and there are many points to be improved on how to deliver specific technologies for improving consumer satisfaction, such as electrical stimulation.

Detailed Description

The objects, certain advantages and novel features of the invention will become more apparent from the following detailed description of the invention and preferred embodiments when considered in conjunction with the accompanying drawings. In the present specification, when reference numerals are given to constituent elements of respective drawings, the same constituent elements are given the same reference numerals even when they are illustrated in different drawings. In describing the present invention, it is determined that the detailed description of the related known art will not make the gist of the present invention unclear, and thus, a detailed description thereof will be omitted.

Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

Fig. 1 is a diagram showing a skin management device of the present invention, fig. 2 is a diagram showing a membrane of a skin management device according to embodiment 1 of the present invention, and fig. 3 is an enlarged view of a in fig. 2.

Fig. 4 is a diagram showing the flow of current in the skin management device according to embodiment 1 of the present invention. Here, fig. 4 (a) shows a one-electrode current flow, and fig. 4 (B) shows a two-electrode current flow.

Referring to fig. 1 to 4, the skin management device 1 of embodiment 1 of the present invention includes a membrane 10, a terminal 20, a ground electrode 30, a cable 40.

The patch 10 is attached to the skin 50 of a user to apply electrical stimulation to the skin 50. In the present description, the film 10 may be in various forms to be attached to the skin 50, and may be, for example, a mask to be attached to the face of the user.

In the case where the sheet 10 is a mask, the sheet 10 is impregnated with a cosmetic, and the sheet 10 applies an electrical stimulus to the skin 50 of the user to promote absorption of the cosmetic.

In the present specification, the skin 50 refers to the entire body of the user including the face. That is, the skin 50 may be used as a concept including parts such as the scalp or lips, and even fingernails and toenails.

The membrane 10 is provided with a plurality of electrodes 11. The electrodes 11 receive current from the terminals 20 for delivery to the skin 50 to effect electrical stimulation at the skin 50. The electrode 11 is formed on the surface of the membrane 10 that contacts the skin 50.

In the present embodiment, the diaphragm 10 includes a first electrode 11a, a second electrode 11b, and a third electrode 11c disposed in contact with each other, and at least a part of the first electrode 11a and the second electrode 11b are disposed to be spaced apart from each other.

That is, the third electrode 11c is disposed between the first electrode 11a and the second electrode 11b, and thereby the first electrode 11a and the second electrode 11b are disposed to be spaced apart from each other by the third electrode 11 c. Specifically, the following is described: the first electrode 11a and the third electrode 11c are disposed so as to be in contact with each other, and the second electrode 11b and the third electrode 11c are also disposed so as to be in contact with each other, but the first electrode 11a and the second electrode 11b are not in contact with each other.

Of course, the third electrode 11c described above may be omitted, and the diaphragm 10 may be provided with the first electrode 11a and the second electrode 11b spaced apart from each other. That is, as long as the diaphragm 10 includes the plurality of electrodes 11 spaced apart from each other, the arrangement is not particularly limited, and various arrangements of the electrodes 11 may be provided.

The electrodes 11 are arranged in such a manner as to drive the membrane 10 in a one-electrode manner or a two-electrode manner, thereby achieving electrical stimulation in various manners. Here, the one-electrode system is a system in which a current supplied from the terminal 20 is transmitted to the skin 50 through the electrode 11 of the diaphragm 10, and then the current flows to the terminal 20 through the ground electrode 30 provided in the ground portion along the body of the user on the skin 50.

In contrast, the two-electrode system is a system in which the current supplied from the terminal 20 is transmitted to the skin 50 through one electrode 11 (for example, the first electrode 11a in the present embodiment) provided in the diaphragm 10, and then flows to the terminal 20 through the other electrode 11 (for example, the second electrode 11b in the present embodiment) provided in the diaphragm 10.

In the case of the one-electrode method, one electrode 11 (or a plurality of electrodes 11 having the same property) is actually provided at a position to which electrical stimulation is to be applied, and is used to embody Iontophoresis (iotophoresis), which is a technique of increasing the skin 50 permeability of an ionic drug by changing the electrical environment of the skin 50 by applying a potential difference to the skin 50, mono-polar RF (Mono-polar RF), or the like.

On the other hand, in the case of the two-electrode method, 2 electrodes 11 having different properties are provided at a portion to which an Electric stimulus is applied, and are used to embody a Micro-current (Micro-current), an EMS (Electric Muscle Stimulation), a Bi-polar radio frequency (Bi-polar RF), and the like.

As described above, the one-electrode system and the two-electrode system differ in the form of electrical stimulation applied to the skin 50, and the one-electrode system and the two-electrode system may be used to manage the skin 50.

In the past, the device embodying the one-electrode system can be used only in the one-electrode system, and the device embodying the two-electrode system can be used only in the two-electrode system. However, in the present embodiment, the one-electrode system or the two-electrode system can be driven by using one diaphragm 10.

For example, in order to drive the diaphragm 10 with one electrode, the diaphragm 10 is energized to the third electrode 11c, and the first electrode 11a to the third electrode 11c are electrically connected to be used as one connected electrode 11.

Of course, as described above, the third electrode 11c may be omitted, and therefore, in this case, the diaphragm 10 uses all of the plurality of electrodes 11 as the electrodes 11 for supplying current. That is, in the one-electrode system, all of the plurality of electrodes 11 provided on the diaphragm 10 are used as the same electrode 11.

However, in the case of driving the diaphragm 10 with one electrode, since it is necessary to recover the current, the ground electrode 30 is provided at the ground portion connected to the body of the skin 50 to which the diaphragm 10 is attached. Therefore, the current transmitted to the skin 50 through the plurality of electrodes 11 provided on the diaphragm 10 flows to the terminal 20 through the ground electrode 30.

In contrast, in order to drive the diaphragm 10 in the two-electrode system, the first electrode 11a and the second electrode 11b are electrically separated without applying current to the third electrode 11c, thereby functioning as electrodes 11 different from each other.

In the case where the third electrode 11c is omitted, the first electrode 11a and the second electrode 11b are kept in a spaced state, and therefore, in this case, the diaphragm 10 uses a part of the electrodes 11 (the first electrode 11a, as an example) among the plurality of electrodes 11 as the electrodes 11 for supplying current, and uses the remaining electrodes 11 (the second electrode 11b, as an example) as the electrodes 11 for recovering current.

Thus, the diaphragm 10 can selectively drive the one-electrode type and the two-electrode type, and the driving of such diaphragm 10 is controlled through the terminal 20.

The terminal 20 is electrically connected to the diaphragm 10 to supply current to the diaphragm 10. In this specification, the terminal 20 may be a mobile phone having the display 22 on the front surface, but the terminal 20 is not limited to a mobile phone in this specification. That is, the terminal 20 may be a power supply for supplying a current to the diaphragm 10.

A cable 40 for transmitting current to the diaphragm 10 is connected to the terminal 20, a jack 21 for connecting the cable 40 is provided in the terminal 20, and the jack 21 may be an earphone jack 21 or the like. However, the connection method, structure, and the like of the cable 40 and the terminal 20 are not particularly limited.

The terminal 20 controls the driving of the diaphragm 10, and the terminal 20 controls the diaphragm 10 to be driven in a one-electrode manner or a two-electrode manner in this embodiment. I.e. the membrane 10 is driven in a one-electrode or two-electrode manner by a signal input by the user to the terminal 20.

The terminal 20 indicates to the user that the diaphragm 10 is currently driven in one-electrode mode or in two-electrode mode. The driving method of the diaphragm 10 is displayed to the user through a display 22 provided on the front surface of the terminal 20 or is audibly notified to the user through a speaker (not shown) provided in the terminal 20.

Of course, the one-electrode mode or the two-electrode mode can be displayed through the terminal 20 and/or can be displayed through the membrane 10 itself. In the case where the diaphragm 10 includes the energizing element 12, as an example, visual signals different from each other visually recognizable are emitted from the energizing element 12 along the flowing direction of the current in the second electrode 11b, and the color of the diaphragm 10 is displayed in different colors so that the user can easily confirm the driving method of the diaphragm 10, and this will be described in detail in other embodiments.

The terminal 20 includes a ground electrode 30 described later. The ground electrode 30 is provided at a ground portion physically connected to the skin 50 to which the membrane 10 is attached, and the ground portion may be another skin 50 at a position spaced apart from the skin 50 to which the membrane 10 is attached.

The ground electrode 30 may be formed in a similar form to the membrane 10 to be attached to the skin 50, but the ground electrode 30 may be provided to the terminal 20 in consideration of a case where the user may carry the terminal 20 with his or her hands.

That is, in the case where the terminal 20 includes the ground electrode 30, the ground portion is a hand of a user holding the terminal 20 when the diaphragm 10 is driven in one-electrode manner. Of course, in the case of driving the diaphragm 10 in a two-electrode manner, there may be no flow of current through the ground portion.

The ground electrode 30 is in contact with the user's body. As described above, the ground electrode 30 is in contact with the ground portion physically connected to the skin 50 to which the membrane 10 is attached, may be formed in close contact with the ground portion together with the membrane 10, and/or may be provided on the side of the terminal 20 that the user carries with his or her hands.

The user attaches the ground electrode 30 to the ground portion and drives the patch 10 in an electrode manner after the skin 50 requiring electrical stimulation is attached to the patch 10, thereby applying electrical stimulation to the skin 50. Alternatively, the user may use the diaphragm 10 by driving it with one electrode in a state where the terminal 20 of the ground electrode 30 is held by the hand without attaching the ground electrode 30 to the ground portion.

However, in the case of using the diaphragm 10 in a two-electrode manner, the user may separate the ground electrode 30 from the ground portion. Of course, in the case where the terminal 20 is provided with the ground electrode 30, the user can continuously carry the terminal 20, and thus the ground electrode 30 can be partially short-circuited at the cable 40 at this time.

That is, when the diaphragm 10 is switched from the one-electrode type to the two-electrode type, since it is not necessary to flow a current through the ground electrode 30, a short circuit is realized in the cable 40 or the like in order to cope with a case where the connection of the ground electrode 30 is not released by the user.

When the user wants to switch the diaphragm 10 from the two-electrode type to the one-electrode type in a state where the ground electrode 30 is not in close contact with the ground portion, the terminal 20 detects that the ground electrode 30 is not connected to the ground portion, and notifies this.

The cable 40 connects the terminal 20 and the diaphragm 10 to form a current transmission path. The cable 40 has one end connected to the insertion hole 21 of the terminal 20 and the other end connected to the diaphragm 10 to form a current transmission path.

In this case, the jack 21 of the terminal 20 connected to one end of the cable 40 may be an earphone jack 21 or the like, but is not particularly limited thereto. In addition, the other end of the cable 40 may be connected to the diaphragm 10 and the ground electrode 30.

At this time, the other ends branched from the cable 40 are electrically separated from each other from one end to the diaphragm 10 and from one end to the ground electrode 30. Namely, the following circuit is formed: the cable 40 has one end connected to the terminal 20 and the other end connected to the electrode 11 of the diaphragm 10 and the ground electrode 30, and is connected in the order of the terminal 20, the diaphragm 10, (the body of the user), the ground electrode 30, and the terminal 20.

The flow of current in the cable 40 may vary depending on the manner in which the diaphragm 10 is driven. For example, when the diaphragm 10 is driven by one-electrode system, the cable 40 transmits a current of the terminal 20 to the electrode 11, and a current is transmitted from the ground electrode 30 to the terminal 20.

In contrast, in the case of driving the diaphragm 10 in the two-electrode system, the cable 40 transmits the current of the terminal 20 to one of the electrodes 11 (for example, the first electrode 11 a), and supplies the current from the other electrode 11 (for example, the second electrode 11 b) to the terminal 20.

By applying electrical stimulation from the electrode 11 to the skin 50 by the flow of such current, a cosmetic effect such as improvement of the skin 50 can be exhibited, and particularly, since the driving method of the diaphragm 10 can be switched in the present embodiment, a desired cosmetic effect can be selectively used.

Thus, in the present embodiment, the membrane 10 may be driven in a one-electrode manner or a two-electrode manner, and various electrical stimuli may be embodied using one membrane 10 according to the user's request, so that the satisfaction can be maximized.

Fig. 5 is a view showing a diaphragm in a skin management device according to embodiment 2 of the present invention, and fig. 6 is a cross-sectional view showing the diaphragm in the skin management device according to embodiment 2 of the present invention.

Referring to fig. 5 and 6, the skin management device 1 according to embodiment 2 of the present invention includes a membrane 10, a terminal 20, a cable 40, and the like, and the following description will mainly be given of the differences of this embodiment from other embodiments described above, and the portions not described above may be replaced with the portions described above.

In the present embodiment, the diaphragm 10 includes a plurality of energization elements 12. The energization element 12 emits a visually identifiable visual signal upon energization. For example, the energization element 12 emits a visual signal such as light or color.

The energization elements 12 are distributed in the patch 10 at the side attached to the skin 50 to deliver electrical stimulation, and are distributed uniformly or non-uniformly. The present embodiment includes the energizing element 12, and thus the energized portion 13a and the non-energized portion 13b can be visually distinguished.

The energizing element 12 can determine whether to emit a visual signal according to whether to energize the lamp. When the user attaches the membrane 10 to the face or the like, some of the plurality of electrodes 11 do not contact the skin 50 well, and thus no electrical stimulation is applied through the electrodes 11.

At this time, the energization element 12 provided in a portion to which the electrical stimulation is applied to the skin 50 (a portion to which the patch 10 is properly attached to the skin 50) emits the visual signal, while the energization element 12 provided in a portion to which the electrical stimulation cannot be applied to the skin 50 (a portion to which the patch 10 is not properly attached to the skin 50) does not emit the visual signal.

In this case, since the energized part 13a, which is a part to which the electrical stimulation is applied, emits a visual signal and the non-energized part 13b, which is a part to which the electrical stimulation is not applied, does not emit a visual signal from the entire diaphragm 10, the energized part 13a and the non-energized part 13b can be easily confirmed by the naked eye of the user.

In addition, the energization element 12 of the present embodiment determines whether or not to emit a visual signal according to whether or not energization is performed, and in addition, emits a different visual signal according to the amount of current. When a current flows, the energization element 12 may generate a visual signal, which represents a different visual signal according to the amount of the current flowing.

For example, the energization element 12 varies at least one of the brightness, color, and color density of the emitted light depending on the amount of current. In this case, the amount of current supplied to each portion where the energization element 12 is provided can be visually confirmed in the diaphragm 10. For example, the film 10 can display a color in a gradation (gradation) form by the energization elements 12 which emit visual signals different from each other.

Therefore, the user can confirm the partial current supply amount of the membrane 10 by the naked eye through the energization element 12, which partial current amount is insufficient or excessive in the skin 50 to which the membrane 10 is attached, and thus can take appropriate measures.

The energizing elements 12 may be unevenly distributed across the membrane 10. That is, the energization elements 12 may be arranged at different distribution densities according to the curvature of the face of the user. As an example, the distribution density of the energization elements 12 in a portion (nose, etc.) where the curvature is relatively large in the face of the user is larger than the distribution density in a portion (forehead, cheek, etc.) where the curvature is relatively small in the face of the user.

As described above, the energizing element 12 can determine whether or not to emit the visual signal according to whether or not to be energized, and therefore the user can confirm that the portion where the visual signal does not appear is not well attached to the skin 50.

However, if the energization elements 12 are not arranged in a sufficient distribution density in a portion having a large curvature such as a nose, even if the membrane 10 is not well adhered to the skin 50 between at least 2 energization elements 12, it is not possible to inform the user of this.

Therefore, the energizing element 12 is more disposed at a portion of the face where the curvature is large. Of course, when the membrane sheet 10 is used not for the face but for the skin 50 which is not curved much as a whole, such as the thigh or the stomach, the energization elements 12 are distributed uniformly. Accordingly, when the same number of current-carrying elements are used for the current-carrying elements 12, visual outputs to the current-carrying portions 13a and the non-current-carrying portions 13b of the diaphragm 10 can be more accurately performed, and effective use of the current-carrying elements and reduction in manufacturing cost can be achieved.

The energization element 12 may be disposed so as to correspond to the plurality of electrodes 11 provided on the diaphragm 10. Accordingly, the energization element 12 can monitor whether or not the electrical stimulation is applied to the skin 50 through the respective electrodes 11, and display this as a visual signal.

In this way, in the present embodiment, the energization portion 13a and the non-energization portion 13b can be distinguished in the diaphragm 10 by the energization element 12, and the user can visually confirm the partial current supply amount in the diaphragm 10, thereby improving the user's convenience.

Fig. 7 is a diagram showing a terminal in the skin management device according to embodiment 3 of the present invention, and fig. 8 is a diagram showing a ground electrode in the skin management device according to embodiment 3 of the present invention.

Referring to fig. 7 and 8, the skin management device 1 of embodiment 3 of the present invention includes a membrane 10, a terminal 20, a ground electrode 30, a cable 40, and the like. In the following, the differences of the present embodiment from the other embodiments described above will be mainly described, and the portions not described above may be replaced with the portions described above.

In the present embodiment, the ground electrode 30 is provided on one surface of the terminal 20 and is contactable with a hand of a user carrying the terminal 20. The terminal 20 may be a mobile phone having a display 22 on the front, so that the user can manage the skin 50 while holding the terminal 20 by hand.

Therefore, in the present embodiment, instead of attaching the ground electrode 30 to a separate ground portion, the ground electrode 30 is disposed on one surface of the terminal 20 using the point that the user carries the terminal 20 by gripping it with the hand, thereby naturally contacting the ground electrode 30 with the hand when the user grips the terminal 20 with the free hand.

Therefore, the ground electrode 30 is exposed to the outside on one surface of the terminal 20. As shown in fig. 7, the ground electrode 30 is fixed to the terminal 20 by a terminal shell 31. That is, the ground electrode 30 is provided on one surface of the terminal housing 31, and the terminal housing 31 is coupled to the rear surface of the terminal 20, etc. Therefore, the ground electrode 30 is disposed at the terminal (20) in a state of being exposed to the outside.

Alternatively, as shown in fig. 8, the ground electrode 30 is disposed on the terminal 20 by an adhesive film 32. That is, the ground electrode 30 is fixed to the adhesion film 32, the adhesion film 32 is made of silicon, rubber, or the like to apply an adhesion substance on one surface or naturally achieve adhesion with a strong frictional force, and the user adheres the adhesion film 32 to the back surface or the like of the terminal 20 to fix the ground electrode 30 to the terminal 20.

Therefore, the ground electrode 30 is disposed on the rear surface of the terminal 20 by bonding of the terminal housing 31, adhesion of the adhesion film 32, or the like, and when the user grasps the terminal 20 with his or her free hand, the fingers, palm, or the like surrounding the rear surface of the terminal 20 reach the ground electrode 30.

The ground electrode 30 is disposed on the left and/or right side of the rear surface of the terminal 20 or on the left and/or right side of the terminal 20 in order to ensure contact between the hand and the ground electrode 30. That is, the ground electrode 30 is not disposed in the center region of the rear surface of the terminal 20.

Even if the user grips the terminal 20 with an empty hand, the central portion of the back surface may be separated from the palm of the user's hand, and thus the ground electrode 30 is disposed at a portion where the hand and the terminal 20 are always in contact when carrying the terminal 20, i.e., the left/right side or the left/right side of the back surface.

At this time, the cable 40 transmits the current of the terminal 20 to the electrode 11, and transmits the current from the ground electrode 30 to the terminal 20. In order to stably induce such a current flow, the ground electrode 30 provided in the terminal 20 and the insertion hole 21 for connecting the cable 40 are electrically separated.

For this purpose, the terminal housing 31 or the attachment film 32 is made of an insulating material to electrically separate the ground electrode 30 from the terminal 20. Therefore, the flow of the current flowing from the ground electrode 30 to the terminal 20 is achieved only by the cable 40, whereby stable skin 50 management can be embodied.

In this way, in the present embodiment, it is not necessary to attach the ground electrode 30 separately to the body of the user, but the grounding is naturally achieved when the user carries the terminal 20 with his or her hands free, thereby greatly improving the convenience of the user.

Fig. 9 is a diagram showing a skin management device according to embodiment 4 of the present invention, and fig. 10 is a diagram showing a ground electrode in the skin management device according to embodiment 4 of the present invention.

Referring to fig. 9 and 10, a skin management device 1 according to embodiment 4 of the present invention includes a diaphragm 10, a terminal 20, a ground electrode 30, a cable 40, and an ear hook 33, and the following description will be mainly made in view of the difference between this embodiment and other embodiments. The parts for which description is omitted may be replaced with the parts described above.

The present embodiment includes an ear hook 33. The ear hook 33 is secured to the ear 60 of the user using the membrane 10. The ear hook 33 has a ground electrode 30 at a portion thereof contacting the ear 60.

The ear hook 33 is fixed to the ear 60 of the user by at least one of a method of hooking to the upper end of the ear 60, a method of hooking to the auricle 61, a method of holding the auricle 61 (a clip form, an auricle clip form, or the like), and a method of inserting into the ear hole 62 (an earphone form, or the like). Of course, the principle, structure, and the like of fixing the ear hook 33 to the ear 60 are not particularly limited in the present embodiment, and the present embodiment describes the ear hook 33, but includes all forms of fixing to the ear 60 (forms of attaching to the ear 60, and the like).

In the case of the other embodiments described previously, the ground electrode 30 is attached to the ground portion in the user's body alone or to the terminal 20. However, in the case of attaching the ground electrode 30, inconvenience occurs during the attachment process, and in the case of disposing the ground electrode 30 on the terminal 20, when the user temporarily drops the terminal 20, the connection of the ground electrode 30 may be cut off. Therefore, in the present embodiment, the ground electrode 30 is simply attached to the ear 60 of the user as with an earphone or an ear 60 ornament.

In this case, the cable 40 transmits the current of the terminal 20 to the electrode 11, and transmits the current from the ground electrode 30 to the terminal 20. The cable 40 is connected to the terminal 20 at one end, to the diaphragm 10 at the other end, and to the ground electrode 30 with the ear hook 33 connected therebetween.

Alternatively, one end of the cable 40 may be connected to the terminal 20 and the other end connected to the ground electrode 30 of the ear hook 33 through the electrode 11 of the diaphragm 10, but the flow path of the current may be embodied as the same path as the aforementioned path.

The cable 40 is supported between the terminal 20 and the diaphragm 10 via the ear hook 33, and thus supported to the ear 60 by the ear hook 33. When the user uses the skin management device 1 in a state where the ear hook 33 is hooked on the ear 60, the cable 40 connected to the electrode 11 from the ear hook 33 can be prevented from slipping off, and thus the membrane 10 can also be prevented from slipping off.

That is, in the present embodiment, the connection of the ground electrode 30 is realized only by the operation of hooking the ear hook 33 to the ear 60, and the diaphragm 10 such as a mask is prevented from slipping down by the ear hook 33, so that there is no inconvenience and the present invention can be used easily.

In addition, the ground electrode 30 is attached to the ground portion separately, and the ear hook 33 is hooked to the ear 60, so that the appearance is simplified, the appearance is improved according to the form of the ear hook 33, and the satisfaction of the consumer can be improved.

As described above, in the present embodiment, the ground electrode 30 is provided on the ear hook 33, and when the user hooks the ear hook 33 on the ear 60, the ground electrode 30 can be easily connected, and the diaphragm 10 can be prevented from slipping off, whereby malfunction and misuse can be reduced.

The present invention may include, in addition to the above-described embodiments, an embodiment in which at least two or more of the embodiments are combined and an embodiment in which at least one or more of the embodiments are combined with a conventional technique.

For example, the present invention may include all embodiments in which the ground electrode 30 is disposed on the terminal 20 and the ear hook 33, and in which the current carrying element 12 is used to display the one-electrode method and the two-electrode method in embodiment 1, and may further include embodiments in which the current carrying element 12 displays the remaining power of the terminal 20 or displays the skin 50 management time.

The present invention has been described in detail with reference to the specific embodiments, but the present invention is not limited thereto, and those skilled in the art can modify or improve the technical idea of the present invention.

The scope of the present invention is further defined by the appended claims, and all changes and modifications that fall within the true spirit and scope of the present invention are intended to be embraced therein.
