Description

  The present invention relates to an olfactory display capable of presenting various scents in a limited time and space.

  There is a scent generating device called an olfactory display capable of generating a scent for a limited time and space. The olfactory display can present various types of scents while switching at high speed. The olfactory display can provide new content that stimulates human visual, auditory, and olfactory sensations by providing a sense of realism by quickly switching the scent to be presented in conjunction with video and sound. It is.

  As one of the conventional methods of the scent generating device, there is a spray method in which liquid perfume is made into a mist and diffused in the air using an atomization technique such as ultrasonic waves. The spray method is suitable for space production that fills a specific space with one kind of fragrance, but as a scent information presentation function that quickly switches and presents various fragrances according to changes in video and audio content. Is not suitable.

  In order to present various scents while switching at high speed in accordance with video and audio contents, it is necessary to remove the scent diffused in a specific space by spraying at once, but it is physically difficult. Further, the mist-like fragrance component adheres to an object (such as furniture or a wall) or clothes around the scent generating device. Due to the fragrance component adhering to surrounding objects, clothes, etc., there is a problem that the scent presented for the video and sound before switching remains even when the video and sound are switched.

  Furthermore, in the case of a system in which liquid fragrance is sprayed in a liquid state, there is a problem that the amount of fragrance consumed is large. When liquid fragrance is provided in a cartridge, if the consumption speed of the fragrance is fast, the cartridge usage period is short and the number of cartridge replacements increases. Further, it is necessary to configure the cartridge so that the liquid fragrance does not leak, which is inconvenient to handle.

  In addition, when providing a scent in conjunction with video and sound, there is a problem that it is desired to reduce the sound generated from the scent generating device as much as possible. In order to add the scent effect to the video and sound without disturbing the reproduction of the video and sound content, it is required to generate the scent with a quiet sound as much as possible.

  In order to solve the problem which arises when using a spray system or a liquid fragrance | flavor among the said problems, in the olfactory display of the following patent document 1, the solid fragrance | flavor source is used. Moreover, in order to solve the problem of reducing the sound generated from the scent generating device among the above-described problems, the olfactory display of Patent Document 1 below uses a diaphragm having a piezoelectric element. Since the piezoelectric element has a low driving sound, there is an advantage that the driving sound of the olfactory display can be reduced.

Japanese Patent No. 6179890

  In the olfactory display disclosed in Patent Document 1, a diaphragm having a piezoelectric element is used as a wind power source for sending out a fragrance. Moreover, the diaphragm which has a piezoelectric element is utilized also as an auxiliary | assistant wind source for accelerating | stimulating the sent out fragrance in an injection direction. Thereby, the operation | movement which accelerates | stimulates a fragrance and injects can be performed, making the drive sound of an olfactory display small.

  On the other hand, a wind power source using a diaphragm having a piezoelectric element has a problem that a sufficient air volume cannot be obtained although the static pressure is high. For this reason, within the rated voltage, there is a restriction on the distance at which the scent is blown. In order to fly the scent further in the jet direction, it is necessary to improve the wind source.

  In order to solve the above problems, an olfactory display according to the present disclosure includes a casing, an aroma cartridge disposed in the casing, an air pump, a centrifugal blower, and an ejection unit.

  The aroma cartridge has an inlet and an outlet and accommodates a solid aroma source. The air pump is connected to the suction port of the scent cartridge and feeds air into the scent cartridge.

  The ejection unit has an aroma passage connected to the discharge port of the aroma cartridge and an air passage connected to the centrifugal blower. An injection unit arrange | positions the fragrance injection port which injects the fragrance sent through the fragrance passage outside, and the air injection port which injects the air sent through the air passage outside. The ejection unit accelerates and sends out the fragrance ejected from the fragrance ejection port with the air ejected from the air ejection port.

  Moreover, in order to solve said subject, another olfactory display which concerns on this indication is provided with a housing | casing, the aroma cartridge arrange | positioned in a housing | casing, an air pump, a centrifugal blower, and an injection unit.

  The aroma cartridge has an inlet and an outlet and accommodates a solid aroma source. The air pump is connected to the suction port of the scent cartridge and feeds air into the scent cartridge.

  The ejection unit has an aroma passage connected to the discharge port of the aroma cartridge, an air passage connected to the centrifugal blower, and a common path connected to the aroma passage and the air passage. An injection unit arrange | positions the common injection port which inject | emits the fragrance and air sent in through the common path outside. An injection unit accelerates the fragrance sent to the common path with the air sent from the centrifugal blower, and sends it out from the common injection port.

  Since the centrifugal blower is used as a wind power source for generating air for accelerating and sending out the fragrance, the fragrance ejected from the ejection unit can be blown farther.

  When a propeller fan is used as a wind power source, there is a problem that due to the characteristics of the wing structure, the air flow is uneven and easily diffuses. By using a centrifugal blower, these problems can be solved, air flowing in one direction can be generated, and air concentrated in the injection direction can be injected.

  Since the scent cartridge is connected to the air pump, the scent injection can be switched on and off at high speed by controlling the air pump. In addition, a wide variety of scents can be enjoyed by replacing the scent cartridge.

  That is, the olfactory display according to the present disclosure is a method in which the fragrance is volatilized by a method in which the fragrance molecules on the surface of the solid fragrance are peeled off by applying outside air to the solid fragrance source (solid fragrance) loaded inside the fragrance cartridge. Prompt. Then, the volatilized scent molecules are ejected to the outside of the olfactory display through the ejection port together with outside air. In the generation of scent molecules, the above problem is solved by using a centrifugal blower that uses air pumps with relatively high static pressure, and when the volatile scent molecules are blown far away, it is difficult for spots to occur in the air flow. ing.

  In the olfactory display of the present disclosure, the air pump is connected to the suction port of the fragrance cartridge through a flexible tube.

  When an air pump is used as a wind power source for sending a scent, a pump-specific noise is accompanied with a pulsating air flow. Examples of noise generated from the air pump include diaphragm driving noise, frictional noise in the air path, and vibration noise from motor rotational vibration.

  In the olfactory display of the present disclosure, the air pump and the aroma cartridge are connected via a flexible tube. Thereby, it is possible to prevent the various noises generated from the air pump from being transmitted to the aroma cartridge. Thereby, it is possible to prevent the scent cartridge from vibrating and generating noise, and transmitting the vibration to the entire apparatus via the scent cartridge and amplifying the noise.

  Further, since the air pump and the aroma cartridge are connected via a flexible tube, the arrangement position of the air pump can be freely adjusted in the apparatus.

  Moreover, in the olfactory display of the present disclosure, the air pump is supported by the casing via the buffer member.

  Since the air pump is supported by the housing via the buffer member, the various noises generated from the air pump can be prevented from being transmitted to the housing. As a result, it is possible to prevent the casing from vibrating and generating noise, and transmitting the vibration to the entire apparatus via the casing and amplifying the noise.

  As the buffer member for supporting the air pump, a short elastomeric tube, for example, a silicone rubber tube having a length of 1 cm or less can be used. By supporting the air pump with the silicone rubber tube, the air pump is suspended in the housing, and the vibration of the air pump can be prevented from being transmitted to each member.

  As a member for supporting the air pump, an elastomeric buffer member having a cavity can also be used. As a member for supporting the air pump to float in the air, various gel agents, various polymers such as porous polyurethane, springs, high-density cotton or fibers can be used.

  In combination with the air pump, the centrifugal blower may be supported by the housing via a buffer member. For example, the vibration sound of the centrifugal blower may be reduced by supporting the centrifugal blower with urethane foam or the like.

  Moreover, in the olfactory display of the present disclosure, the ejection unit is supported with respect to the casing so that the blower shaft of the air sent out from the ejection unit can be changed.

  It is possible to freely adjust the direction of the ejection unit toward the user's face. Accordingly, it is possible to present the scent to the user at an appropriate timing in conjunction with video and audio content. In addition, since the scent injection direction can be freely changed while the olfactory display casing is fixed, the degree of freedom of the installation location of the olfactory display is increased.

  In the olfactory display of the present disclosure, the air pump operates at a voltage lower than the rated voltage.

  When the air pump is driven, the air pump is driven at a voltage lower than the rated voltage, for example, ½ or less of the rated voltage, so that noise caused by driving the air pump can be further reduced. The drive sound of the air pump may be lowered by controlling the control pulse of the air pump.

  In the olfactory display of the present disclosure, the centrifugal blower operates at a voltage lower than the rated voltage.

  When the centrifugal blower is driven, since the centrifugal blower is driven at a voltage lower than the rated voltage, for example, ½ or less of the rated voltage, it is possible to further reduce noise due to the driving of the centrifugal blower. The drive sound of the centrifugal blower may be reduced by controlling the control pulse of the centrifugal blower.

  Moreover, the olfactory display of this indication is further equipped with the aperture | diaphragm | squeeze unit attached to an injection | spray unit, and variably adjusting the injection range of the fragrance | air_jet injected from an injection unit.

  The injection range of the fragrance injected from the injection unit can be changed. For example, it is possible to make adjustments such as injecting an aroma into a relatively wide range or injecting an aroma only at a specific position.

  As the solid fragrance source used in the olfactory display of the present disclosure, a solid fragrance containing a porous material, clay mineral, gel, high-density cotton or fiber, or the like can be used.

  In the olfactory display of the present disclosure, a combination of an air pump and a centrifugal blower is used as a wind power source for sending air into the scent cartridge and a wind power source (auxiliary wind power source) for accelerating the flow of the scent. In addition to the above, combinations of the above two wind sources include ion generators and various fans (propeller, sirocco, turbo, mixed flow, line flow, etc.), ultrasonic vibrators and fanless blowers, air pumps, A combination of a circulator and a combination of a diaphragm having a piezoelectric element and a circulator can be used. Moreover, it is also possible to use combinations in which these listed combinations are interchanged.

  According to the olfactory display of the present disclosure, since the centrifugal blower is used as a wind power source that accelerates the flow of the scent to be ejected, it is possible to fly the scent further. Further, by controlling the air pump, it is possible to switch ON / OFF of fragrance injection and present it at high speed. Furthermore, a wide variety of scents can be enjoyed by replacing the scent cartridge.

{First embodiment}
Hereinafter, the olfactory display 10A according to the first embodiment will be described with reference to FIGS. The olfactory display 10A has no particular vertical and horizontal directions and can be installed at any angle. For convenience of explanation, FIG. 1 will be described as a plan view of the olfactory display 10A.

  As shown in FIG. 1, the casing 80 of the olfactory display 10A has a substantially rectangular shape in plan view. In FIG. 1, a lower cover 81 constituting a bottom surface 811 and a side surface 812 of the housing 80 is shown. The side surface 812 is provided upward from the entire peripheral edge of the bottom surface 811. In FIG. 1, in order to show the internal structure of the olfactory display 10 </ b> A, an upper cover (see FIGS. 13 to 18 for the upper cover 82) constituting the upper surface and the side surface of the housing 80 is shown in a removed state. .

  A centrifugal blower 20 </ b> A is placed on the bottom surface 811 of the lower cover 81. The centrifugal blower 20A includes a blower body 201 that accommodates a runner (forward-facing blade). A motor (not shown) is disposed below the blower body 201. When the motor disposed at the lower portion of the blower body 201 is rotationally driven, the runner disposed coaxially with the motor in an annular shape is rotationally driven. A rotational flow in a direction substantially perpendicular to the rotation axis is generated by the rotational drive of the runner. In FIG. 1, arrow D1 is the direction of the swirl flow. As the centrifugal blower, for example, a DC centrifugal blower of E0515H series manufactured by Nidec Servo Corporation can be used.

  A duct 202 is connected to the side of the blower body 201. The duct 202 is connected to an opening provided in a side portion of the blower main body 201, and a swirl flow generated by the rotational drive of the runner flows in. The duct 202 is bent in a substantially L shape in plan view.

  FIG. 3 is a view showing a state in which an ejection unit 50A described later is removed from the olfactory display 10A. The duct 202 is bent in a substantially L shape and then extends to the lower part of the injection unit 50A. The front end of the duct 202 is bent upward and has an opening 203 facing the lower surface of the ejection unit 50A.

  On the bottom surface 811 of the lower cover 81, air pumps 31, 32, 33 are placed via a plurality of buffer members 91, 91. Buffer members 91, 91... Are attached to the upper and lower portions of the air pumps 31, 32, 33, respectively. 1 are provided on top of the air pumps 31, 32, 33, and are disposed so as to contact the lower surface of the upper cover 82.

  Further, as shown in FIGS. 2 and 3, buffer members 91, 91... Are also attached to lower portions of the air pumps 31, 32, 33. Although only the buffer member 91 attached to the lower part of the air pump 33 is visible in the figure, the buffer member 91 is similarly attached to the lower part of the air pumps 31 and 32. The lower ends of the buffer members 91, 91... Provided at the lower parts of the air pumps 31, 32, 33 are fixed to the bottom surface 811 of the lower cover 81.

  As shown in FIGS. 1 and 2, buffer members 92, 92, 92... Are also provided on the sides of the air pumps 31, 32, 33. Of the side surface of the air pump 31, the end portions of the buffer members 92, 92 provided on the side surface near the side surface 812 of the lower cover 81 are fixed to the side surface 812. Of the side surface of the air pump 33, the end portions of the buffer members 92, 92 provided on the side surface close to the centrifugal blower 20 </ b> A are fixed to a partition wall (not shown) provided in the lower cover 81.

  One end of each end of the buffer members 92, 92 provided between the air pump 31 and the air pump 32 is fixed to the side surface of the air pump 31, and the other end is fixed to the side surface of the air pump 32. One end of each end of the buffer members 92, 92 provided between the air pump 32 and the air pump 33 is fixed to the side surface of the air pump 32, and the other end is fixed to the side surface of the air pump 33.

  As described above, the air pumps 31, 32, 33 are provided with the buffer members 91, 91... Or the buffer members 92, 92. There is no contact. The air pumps 31, 32, 33 are supported so as to float in the housing 80 via the buffer members 91, 91... And the buffer members 92, 92. It is possible to prevent the noise generated from the air pumps 31, 32, 33, that is, the diaphragm driving sound, the frictional sound in the air path, or the vibration sound from the rotational vibration of the motor from being directly transmitted to the housing 80.

  Since it is possible to prevent drive sound, friction sound, vibration sound, and the like generated from the air pumps 31, 32, and 33 from being directly transmitted to the casing 80, the casing 80 vibrates and generates noise, Therefore, it is possible to prevent the vibration from being transmitted to the entire apparatus and amplifying the noise.

  As the buffer members 91 and 92 that support the air pumps 31, 32, and 33, short elastomeric tubes, for example, silicone rubber tubes having a length of 1 cm or less can be used. By supporting the air pumps 31, 32, 33 with the silicone rubber tube, the air pumps 31, 32, 33 are suspended in the housing, and vibrations of the air pumps 31, 32, 33 can be prevented from being transmitted to each member. . In addition, various gel agents, various polymers such as porous polyurethane, springs, high-density cotton, or fibers can be used as members that support the air pumps 31, 32, and 33 to float in the air.

  In the present embodiment, each of the air pumps 31, 32, 33 is provided with buffer members 91, 91... At two places on the upper part and two places on the lower part. 92 ... are attached. However, the number and mounting positions of the buffer members are not limited to this. The number and position of the buffer members can be adjusted so that the air pumps 31, 32, 33 can be supported so as not to directly contact the casing 80 or other components.

  The configuration of the air pumps 31, 32, 33 used in the present embodiment is not particularly limited. For example, Koge Micro Tech Co. Ltd. KPM series mini air pumps can be used.

  As shown in FIG. 1, tubes 311, 321, and 331 are connected to the air injection ports 310, 320, and 330 of the air pumps 31, 32, and 33, respectively. The tubes 311, 321, and 331 are made of a flexible material such as silicone rubber or soft vinyl chloride, for example. The air pumps 31, 32, and 33 accommodate motors (not shown), respectively, and the pump mechanism is activated by driving the motors so that air is ejected from the ejection ports 310, 320, and 330. Air injected from the injection ports 310, 320, and 330 of the air pumps 31, 32, and 33 flows through the tubes 311, 321, and 331.

  As shown in FIG. 1, the other ends of the tubes 311, 321, and 331 are connected to suction ports 411, 421, and 431 of the aroma cartridges 41, 42, and 43, respectively. Thereby, the air injected from the air pumps 31, 32, 33 is sent into the aroma cartridges 41, 42, 43 through the tubes 311, 321, 331, respectively.

  As shown in FIG. 3, the fragrance cartridges 41, 42, and 43 have a fan shape in plan view. The cross sections at arbitrary positions in the height direction of the aroma cartridges 41, 42, and 43 have a fan-like shape that is substantially the same as the planar view shape. The aroma cartridges 41, 42, and 43 are detachably attached to the bottom surface 811 of the lower cover 81. The aroma cartridges 41, 42, and 43 are filled with different types of solid aroma sources. It is possible to inject various types of fragrances by replacing and mounting fragrance cartridges filled with various types of fragrance sources as the fragrance cartridges 41, 42, and 43.

  As the solid fragrance source filled in the fragrance cartridges 41, 42, 43, a solid fragrance containing clay mineral, gel, high-density cotton, fiber, or the like can be used. The aroma cartridges 41, 42, and 43 can be filled with various scent components such as various flower scents and various fruit scents according to the user's preference.

  As shown in FIG. 3, discharge ports 412, 422, and 432 are provided on the upper surfaces of the aroma cartridges 41, 42, and 43, respectively. When air is sent into the fragrance cartridges 41, 42, 43 through the suction ports 411, 421, 431, the fragrance molecules on the surface of the solid fragrance source are peeled in the fragrance cartridges 41, 42, 43. The fragrance is volatilized. Then, the volatilized scent molecules are ejected together with air from the discharge ports 412, 422, and 432 to the outside of the aroma cartridges 41, 42, and 43.

  As shown in FIGS. 1 and 2, an injection unit 50 </ b> A is placed on the fragrance cartridges 41, 42, and 43. The injection unit 50A has an air passage and an aroma passage (not shown).

  As described with reference to FIG. 3, the duct 202 of the centrifugal blower 20A extends to the lower part of the injection unit 50A. And the front-end | tip of the duct 202 bends upwards, and the opening 203 is provided in the edge part. The opening 203 is connected to an air passage provided inside the injection unit 50A. The air passage extends in the up-down direction in the injection unit 50A, and the diameter of the passage becomes smaller toward the upper side. The upper end of the air passage is connected to the air injection port 501 shown in FIGS.

  With such a structure, the air sent out from the centrifugal blower 20 </ b> A passes through the duct 202 and is blown upward from the opening 203. The air blown upward from the opening 203 passes through the air passage in the injection unit 50A and is sent out linearly upward from the air injection port 501.

  As described with reference to FIG. 3, the discharge ports 412, 422, and 432 are provided on the upper surfaces of the aroma cartridges 41, 42, and 43, respectively. The discharge ports 412, 422, and 432 are respectively connected to three aroma passages (first to third aroma passages) provided inside the injection unit 50 </ b> A. The first to third aroma passages are provided individually. The first to third aroma passages extend in the up-down direction in the injection unit 50A. And the upper end of the 1st-3rd aroma channel | path is connected to the aroma injection port 511,521,531, as shown in FIG. 1 and FIG.

  The discharge port 412 of the fragrance cartridge 41 is connected to the fragrance injection port 511 through the first fragrance passage in the injection unit 50A. With such a structure, the air sent out from the air pump 31 is sent into the aroma cartridge 41 through the tube 311. The fragrance component peeled from the solid fragrance source by the air fed into the fragrance cartridge 41 is sent out from the discharge port 412. The fragrance component sent upward from the discharge port 412 is injected upward from the fragrance injection port 511 through the first fragrance passage in the injection unit 50A.

  The discharge port 422 of the fragrance cartridge 42 is connected to the fragrance injection port 521 through a second fragrance passage in the injection unit 50A. With such a structure, the air sent out from the air pump 32 is sent into the aroma cartridge 42 through the tube 321. The fragrance component sent out from the fragrance cartridge 42 is ejected upward via the discharge port 422, the second fragrance passage, and the fragrance ejection port 521.

  The discharge port 432 of the fragrance cartridge 43 is connected to the fragrance injection port 531 via a third fragrance passage in the injection unit 50A. With such a structure, the air sent out from the air pump 33 is sent into the aroma cartridge 43 through the tube 331. The fragrance component sent out from the fragrance cartridge 43 is ejected upward through the discharge port 432, the third fragrance passage and the fragrance ejection port 531.

  The jet unit 50 </ b> A is configured such that a part of the upper portion is exposed to the outside of the housing 80 in a state where the upper cover 82 is covered. The air injection port 501 and the fragrance injection ports 511, 521, and 531 are provided at positions exposed to the outside of the housing 80 on the surface of the injection unit 50A with the upper cover 82 covered.

  The fragrance components injected from the fragrance injection ports 511, 521 and 531 are injected upward by the air pressure sent from the air pumps 31, 32 and 33. The aroma components injected from the aroma injection ports 511, 521 and 531 are further accelerated by the air injected from the air injection port 501.

  Specifically, the first to third aroma passages provided in the injection unit 50A extend in a substantially vertical direction (a direction substantially perpendicular to the bottom surface 811) in the plan view of FIG. The fragrances injected from the fragrance injection ports 511, 521, and 531 are injected substantially upward through the fragrance passages. Further, the air passage provided in the injection unit 50A extends in a substantially vertical direction (a direction substantially perpendicular to the bottom surface 811) in a plan view of FIG. 1, and is injected from the air injection port 501 through the air passage. The fragrance is jetted substantially upward. Thereby, the fragrances injected from the fragrance injection ports 511, 521 and 531 are accelerated by the air injected from the air injection ports 501 and further sent upward. In this way, by using the air pressure by the centrifugal blower 20A, the fragrance can be blown farther.

  As shown in FIGS. 1 to 3, a power supply 60 and a circuit board 70 are arranged on the bottom surface 811 of the housing 81. The power supply 60 supplies power to the circuit board 70. The power source 60 supplies power to the centrifugal blower 20A and the air pumps 31, 32, 33 via a harness (not shown).

  On the circuit board 70, a CPU, a memory, and the like are arranged. The CPU outputs a control signal to the centrifugal blower 20A and the air pumps 31, 32, 33. Centrifugal blower 20A and air pumps 31, 32, and 33 perform motor drive and stop control based on control signals input from the CPU.

  A connector 71 is provided on the circuit board 70. The connector 71 is located at the opening of the lower cover 81 of the housing 80. By connecting a communication cable such as a USB cable connected to an external computer such as a tablet, a smartphone, or a personal computer to the connector 71, the computer can be connected to the circuit board 70. Thereby, the olfactory display 10A can be controlled from an external computer such as a tablet.

  For example, video and sound are reproduced on a tablet. Then, a fragrance control command generated in conjunction with the image and sound is output from the tablet. A control command output from the tablet is input to the CPU of the circuit board 70 via the USB cable and the connector 71. The CPU of the circuit board 70 controls the centrifugal blower 20A and the air pumps 31, 32, 33 in accordance with a control command from the tablet, and generates a desired scent.

  For example, it is assumed that the scent cartridge 41 is filled with a rose scent, the scent cartridge 42 is filled with an orange scent, and the scent cartridge 43 is filled with a scent source of jasmine scent. The tablet outputs a control command that generates a scent of roses in conjunction with video and sound. In response to this, the olfactory display 10A drives the air pump 31 and the centrifugal blower 20A to generate a rose scent. Alternatively, the tablet outputs a control command for generating a scent mixed with orange and jasmine in conjunction with video and sound. In response to this, the olfactory display 10A drives the air pumps 32, 33 and the centrifugal blower 20A to generate an orange scent and a jasmine scent.

  1 and 2, the injection unit 50 </ b> A is provided with six openings around the air injection port 501. In this embodiment, since three fragrance cartridges 41, 42, and 43 are used, three corresponding fragrance injection ports 511, 521, and 531 are used. When four or more fragrance cartridges are used, four or more fragrance injection ports can be used. For this reason, in the injection unit 50A, six aroma passages are formed corresponding to the six aroma injection ports and the six aroma cartridges. Of course, it is good also as a structure which has only three fragrance injection openings. In this case, three aroma passages may be provided in the injection unit 50A. Or it is good also as a structure which has only two fragrance injection openings. In this case, it is only necessary to provide two aroma passages in the injection unit 50A.

  In the olfactory display 10A of the present embodiment, the air pumps 31, 32, and 33 are controlled to operate at a voltage lower than the rated voltage. For example, the air pumps 31, 32, and 33 are driven at 1/2 or less of the rated voltage. Thereby, it is possible to reduce the noise caused by driving the air pumps 31, 32, 33. For example, Koge Micro Tech Co. If the Ltd. KPM series mini air pump is used, the rated voltage is 3V. Noise can be reduced by driving the minipump, for example, at 1 V, which is 1/3 of the rated voltage. You may make it reduce the drive sound of the air pumps 31, 32, and 33 by controlling the control pulse of an air pump.

  In the olfactory display 10A of the present embodiment, the centrifugal blower 20A is controlled to operate at a voltage lower than the rated voltage. For example, the centrifugal blower 20A is driven at 1/2 or less of the rated voltage. Thereby, it is possible to reduce the noise caused by driving the centrifugal blower 20A. For example, when using a DC centrifugal blower of Nidec Servo Corporation's E0515H series, the rated voltage is 12V. By driving this centrifugal blower with 4V, which is 1/3 of the rated voltage, for example, noise can be reduced. The drive sound of the centrifugal blower 20A may be reduced by controlling the control pulse of the centrifugal blower 20A.
