BEST MODE FOR CARRYING OUT THE INVENTION Preferred embodiments of the present invention will be described below with reference to the drawings.

Embodiment 1. 1 is a perspective view showing a first embodiment of a stereoscopic sound image output device according to the present invention, FIG. 2 is a front view of the device shown in FIG. 1, similarly FIG. 3 is a plan view, and FIG. It is a right side view. As is clear from each figure,
The stereoscopic sound image output device according to the present embodiment is a headphone. It should be noted that the input code of the signal for the stereoscopic sound image is omitted in FIGS.

A headphone-shaped three-dimensional sound image output device (hereinafter, “receiver”) 1 is composed of a main frame 2 and a pair of three-dimensional sound image output units 3. The main frame 2 is a headband for mounting this device as a headphone on the user, and the stereoscopic sound image output unit 3 is attached to both ends thereof. The stereoscopic sound image output unit 3 may be attached only to at least one end side. The main frame 2 in the present embodiment is
The three-dimensional sound image output unit 3 is connected by inserting the bent portion into a connection hole provided at the connection portion of each three-dimensional sound image output unit 3 There is. With the connecting portion having such a structure, each stereoscopic sound image output unit 3 is attached to the main frame 2 so as to be rotatable about the insertion portion, that is, the angle can be adjusted. Further, the main frame 2 has an elastic force that urges it in the ear direction at the time of wearing, and this urging force prevents each stereoscopic sound image output unit 3 from slipping off from each ear of the user at the time of wearing. To work. Further, this elastic force facilitates mounting of the receiver 1 regardless of the size of the face width. Further, the main frame 2 has a sufficient length so that each stereophonic image output unit 3 can be positioned almost at each ear of the user even when worn by any user.

The three-dimensional sound image output units 3 are formed symmetrically with respect to the center line of the face, and are configured for the right ear and the left ear, respectively. In the following description, one stereoscopic sound image output unit 3 will be focused and described.

The stereoscopic sound image output unit 3 in the present embodiment is composed of a small speaker 4, a speaker fixing portion 5, an upper positioning arm 6 and a lower positioning arm 7, and one of them corresponds to a state in which the user wears the same. Outputs a stereoscopic sound image at the ear.

The small speaker 4 is a sound wave output means for inputting a signal sent from the reproducing device via an input cord (not shown) and outputting a sound wave. In the present embodiment, three small speakers 4 are arranged corresponding to each ear.
Each small speaker 4 is a full-range speaker, and the outputs from the three small speakers are combined to reproduce a three-dimensional sound field at the user's ear.

The speaker fixing section 5 fixes the three small speakers 4 so that a sound image plane can be formed in a three-dimensional space by the coordinate vector of the sound output from each small speaker 4. As is apparent from FIG. 3, the speaker fixing portion 5 is curved so that the output sound from each small speaker 4 is directed toward the user's ear hole in the mounted state. Then, in the mounted state, the two small speakers 4 are located in front of the ear axis connecting the ears (downward in the drawing).
In addition, one small speaker 4 is arranged behind the ear axis. This makes it possible to reproduce a stereoscopic sound image that wraps around from behind.

The upper positioning arm 6 and the lower positioning arm 7 come into contact with the vicinity of the ears by the urging force of the main frame 2 when they are mounted, so that the user holds the speaker fixing portion 5 to which the small speaker 4 is fixed. It is a positioning means that holds the device so that it is always positioned at a predetermined distance from the ear even when it is moved. Each of the positioning arms 6 and 7 is formed by covering a wire that is not easily bent by an external force with a flexible material.
The respective positioning arms 6 and 7 are as shown in FIG.
It has a substantially U-shape when viewed from above and below. The positioning means having such a shape does not block the entire ear even when the user wears it.

The upper positioning arm 6 extends from the position where it is attached to the speaker fixing portion 5 and contacts above the user's ear, while the lower positioning arm 7 contacts below the user's ear, which extends. The length keeps a predetermined distance between the ear and the small speaker 4. The predetermined distance from your ears is
It is comprehensively determined by the signal value of the three-dimensional sound field to be reproduced, the direction of the small speaker 4, and the like.

Further, in the present embodiment, as shown in FIG. 3, the positioning arms 6 and 7 are extended from the mounting position of the speaker fixing portion 5 in the direction of expanding the position of the user's head. The length of the contact part is made longer. This makes it possible to more reliably prevent the rotational displacement of the stereoscopic sound image output unit 3 even when the user moves while wearing the device. In particular, by making the contacting portion of the upper positioning arm 6 slightly concave so as to follow the shape of the head, the effect of preventing rotational deviation can be further enhanced.

The way of mounting the receiver 1 in this embodiment is basically the same as that of the conventional headphone. That is, with each hand, each stereophonic image output unit 3
Alternatively, by holding the main frame 2 portion in the vicinity thereof and spreading the main frame 2 in the direction opposite to the biasing force of the main frame 2 in the ear direction, the stereo sound image output unit 3 is placed on the head so as not to hit the ear. Then, in the present embodiment, the receiver 1 can be attached by putting the upper positioning arm 6 on the ear and releasing the hand.
FIG. 5 is a perspective view of the receiver 1 when mounted.
Is fixed at its mounting position by balancing the urging force of the main frame 2 with the reaction force generated by the contact of the positioning arms 6 and 7 above and below the ears. In particular, in the present embodiment, as apparent from FIG. 2, when the user wears the main frame 2 and the stereoscopic sound image output unit 3, the rotatable connecting portion is seen from the front of the user. Since the height 2a is the same as the mounting position of the upper positioning arm 6, the stereoscopic sound image output unit 3 can be securely fixed. That is,
The main frame 2 has an inward urging force, and this urging force acts on the connecting portion 2a to rotate the stereoscopic sound image output unit 3. Needless to say, this rotation direction is the direction in which the connecting portion 2a tries to enter the inside, but since the mounting position of the upper positioning arm 6 is arranged on the direction line in which it acts, the upper positioning arm 6 is provided to the user. The contact force can be effectively suppressed by the contact. Further, the stereoscopic sound image output unit 3 can be stabilized around the ear by the upper positioning arm 6 receiving the rotational force.

According to the present embodiment, when the receiver 1 is mounted on the user as described above, the receiver 1 does not move from the user's head even if the user moves his / her head. Fixed. Therefore, the positional relationship between the ears and the small speaker 4 can always be kept constant, so that the stereophonic image can be heard by the user with good sound quality.

In this embodiment, the three-dimensional sound image output unit 3 can be fixed to the ear by the urging force (inward tension) of the main frame 2, so that the length adjusting mechanism of the main frame 2 is not required. It is unnecessary. When a user with a relatively small head such as a small child uses the receiver 1 according to the present embodiment, the main frame 2
Is attached in a floating state without touching the head. Of course, a length adjusting mechanism may be provided if the user wants to wear it while touching the head.

When mounted, the sound image plane formed by the small speaker 4 is mounted so as to intersect perpendicularly with the straight line connecting the midpoint of both eyes and the center of the mouth, and to include the ear axis connecting each ear. Is desirable. Then, when the stereoscopic sound image output unit 3 is correctly positioned, as described above, the two small speakers 4 are located in front of the ear axis and one small speaker 4 is located in a position behind the ear axis and away from the ear. The recorded three-dimensional sound field can be faithfully reproduced.

As described above, in order to faithfully reproduce the recorded three-dimensional sound field, positioning the small speaker 4 as described above is an important factor. Since the positioning arm 6 and the lower positioning arm 7 are provided, the small speaker 4 can be easily localized at an appropriate position, and the positional deviation can be surely prevented.

In this embodiment, the stereoscopic sound image output unit 3 is rotatably attached to the main frame 2 so that the angle with respect to the main frame 2 can be adjusted.
The lower positioning arm 7 is provided, and the upper and lower positioning arms 6 and 7 are brought into contact with the upper and lower parts of the ear to fix the stereoscopic sound image output unit 3 at a desired position. If it is fixed to the frame 2, it is possible to position and prevent rotation of the stereoscopic sound image output unit 3 only by the upper positioning arm 6.

Embodiment 2. FIG. 6 is a front view showing only the main part of the second embodiment of the headphone type three-dimensional sound image output device according to the present embodiment. A feature of this embodiment is that the upper positioning arm and the lower positioning arm, which are formed as the positioning means in the above-described first embodiment, are integrated and can slide in the arm extending direction with respect to the stereoscopic sound image output unit 3.

By integrally forming the above, one wire is formed into a rectangular frame, and as shown in FIG. 6, it is formed into a substantially arc shape when viewed from the front. In the speaker fixing part 5,
A hole 9 having a diameter substantially equal to that of the wire forming the positioning arm 8 is provided, and the positioning arm 8 passing through the hole 9 is held so as not to move due to friction with the inner wall of the hole 9 and It is possible to slide in the hole 9 by the force of.

For example, it is assumed that a certain user a fixes the positioning arm 8 at the position shown in FIG. 6A and is using the receiver according to the present embodiment. For the user a, the adjustment position of the positioning arm 8 shown in FIG. 6A is the position where the small speaker 4 can be adjusted to an appropriate position as described above.

It is assumed that another user b uses this receiver. It is assumed that the user b has a round face relatively to the user a whose face contour is an inverted triangle. At this time, the user b moves the positioning arm 8 so as to increase the length extending upward from the speaker fixing portion 5 as shown in FIG.
Slide in the direction of arrow A.

As described above, according to the present embodiment, the length of the portion of the positioning arm 8 extending upward / downward from the speaker fixing portion 5 can be adjusted, so that the contour of the user's face can be adjusted. Especially, even if there are variations in the shape of the side surface of the face, the placement of the small speakers 4 can be localized at the optimum position.

In the present embodiment, the upper positioning arm and the lower positioning arm shown in the first embodiment are integrated so that the stereoscopic sound image output unit 3, that is, the small speaker can be adjusted to an appropriate angle. Formed. With such a structure, the user can easily adjust the positioning. Further, the number of parts can be reduced even from the manufacturing process of the receiver, and the assembly thereof can be simplified. However, if cost is not taken into consideration, the small speaker 4 can be localized at an ideal position as a structure in which the extension length of at least one of the upper positioning arm 6 and the lower positioning arm 7 in the first embodiment can be adjusted. You may do it.

Embodiment 3. 7 is a perspective view showing Embodiment 3 of the stereoscopic sound image output apparatus according to the present invention, FIG. 8 is a front view of the apparatus shown in FIG. 7, similarly FIG. 9 is a plan view, and FIG. It is a right side view. As is clear from each figure, the stereoscopic sound image output device in the present embodiment is characterized by the frame shape of glasses. It should be noted that the input code of the signal for the stereoscopic sound image is omitted in FIGS. 7 to 10. Further, the same components as those in the first embodiment are designated by the same reference numerals.

The spectacle frame-shaped three-dimensional sound image output device (hereinafter, “receiver”) 11 is composed of a spectacle frame-shaped frame 12 and a pair of three-dimensional sound image output units 13. The frame 12 has a pad 12a that abuts on both sides of the root of the nose and a temple portion 12b that is placed on the ear. Of course, in the case of the present embodiment, the spectacle lens is not necessary, so that there is no rim. Each temple 1 of the frame 12
The stereophonic sound image output units 13 are attached to the 2b, respectively, and when worn by the user, the stereoscopic sound image output unit 13 is positioned at the user's ears. In addition,
The stereoscopic sound image output unit 13 may be attached only to at least one end side.

The three-dimensional sound image output unit 13 in this embodiment is composed of a small speaker 4, a speaker fixing portion 5 and a positioning arm 14, and produces a three-dimensional sound image at one of the corresponding ears when it is worn by the user. Output. Since the structures of the small speaker 4 and the speaker fixing portion 5 are the same as those in the first embodiment, the description will be omitted. The positioning arm 14 extends in a direction away from the temple portion 12b, and the speaker fixing portion 5 and the temple portion of the frame 12 are positioned so that each speaker 4 is always positioned at a predetermined distance from the ear in the mounted state. Connect to 12b. The predetermined interval here is the same as that in the first embodiment, and is comprehensively determined by the signal value of the three-dimensional sound field to be reproduced, the orientation of the small speaker 4, and the like.

The receiver 11 of the present embodiment can be mounted by mounting the pad 12a and the temple 12b of the frame on the nose and the ear, respectively, as in a general eyeglass frame. The mounted state is shown in FIG. As shown in FIG. 9, the two positioning arms 14 on one ear side are joined to the temple portion 12b at distant positions, and are arranged so as to come to the front and back of the ear when they are worn. By arranging them apart from each other in this manner, the receiver 11 can be placed on the ear in a well-balanced and stable state.

As in the first embodiment, when the user wears the receiver 11, the sound image plane formed by the small speaker 4 is perpendicular to the straight line connecting the midpoint of both eyes and the center of the mouth. Ideally, it is fitted so as to include the ear shafts that connect each ear as they intersect. In other words,
Receiver 11 so that the user can wear it in an ideal position
Is designed. Then, when the stereoscopic sound image output unit 3 is correctly positioned, as described above, the two small speakers 4 are located in front of the ear axis and one small speaker 4 is located in a position behind the ear axis and away from the ear. The recorded three-dimensional sound field can be faithfully reproduced.

Further, the frame 12 is tensioned inwardly like a general eyeglass frame, and the tension fixes the receiver 11 to the user. It is more effective if the pad 12a and the temple portion 12b that come into contact with the user are made of a material having a large frictional force.

According to the present embodiment, when the receiver 11 is mounted on the user as described above, the receiver 11 does not shift from the user's head even if the user moves his / her head. Fixed. Therefore, the positional relationship between the ears and the small speaker 4 can always be kept constant, so that the stereophonic image can be heard by the user with good sound quality.

Unlike the first embodiment, in the present embodiment, the lower positioning arm that abuts under the ear is not provided, and the frame 12 is suspended from the positioning arm 14 extending from the temple 12b. The speaker fixing portion 5 is fixed by. Therefore, depending on the material of the frame 12 or the positioning arm 14 and the total weight of the speaker fixing portion 5, the frame 12 or the positioning arm 14 may bend as the user moves. Also, the speaker fixing portion 5 may feel heavy. Therefore, in the case where such a problem occurs, the first embodiment is also used in the present embodiment.
Similarly, a lower positioning arm that abuts below the ear may be provided.

Further, in this embodiment, the temple portion 12b of the frame 12 is attached to the frame body so as to be extendable and contractible. That is, the temple portion 12b formed as a separate component from the frame body is fitted into the attachment portion 12c so as not to separate, and the frame 12 is formed with a structure in which the temple portion extends from the attachment portion 12c. ing. Although there are variations in the size of the face, according to the present embodiment, by adjusting the length of the temple of the frame 12, the placement of the small speaker 4 can be set to an optimum position regardless of the size of the face of the user.
