[Prior art] Although a general hearing aid uses a sound pressure type loudspeaker that transmits sound by air vibrations, a bone conduction loudspeaker that uses bone vibrations to convey sound signals and is hardly affected by external sounds has recently appeared Bone conduction hearing aid. Bone conduction hearing aids need to have their loudspeakers pressed against a part of the cranium for use, so when installing them, for example, a headband 3 2 with a bone conduction loudspeaker 31 installed at one end is used. The method of pressing the bone conduction microphone 31 on the peripheral part of the ear on the side of the head (refer to FIG. 4), or through the hook 3 3 of the eyeglasses of the bone conduction microphone 31 on the end, and then A method in which the bone conduction microphone 31 is brought into close contact with the back part of the ear (see FIG. 5). Therefore, it can be immediately seen that hearing aids are being used. In addition, when a bone conduction type microphone is used, it is necessary to transmit sound vibration to the cranium. Therefore, compared with the use of a general sound pressure type microphone, it has a disadvantage of a large power consumption. [Summary of the Invention] (Problems to be Solved by the Invention) As explained above, since the bone conduction hearing aids of the prior art are known to have hearing aids installed, they are suitable for those who do not want to know that hearing aids are installed. Pieces) / 93-04 / 93100760 200417268 becomes inconvenient, and it also has the disadvantage of large power consumption, so the problem of the present invention is to provide that such a problem does not occur, that is, it is completely unknown from the outside that a hearing aid is installed Bone conduction hearing aids that can minimize power consumption. (Means for Solving Problems) It is known that teeth are most effective in transmitting sound and vibration through bone conduction. The present inventors have completed the present invention based on this knowledge. In order to solve the above problems, the bone conduction hearing aid of the present invention is Contains a transmitting unit of a microphone for sound collection and a sound signal transmitting mechanism; and a bone conduction amplifier which is separated from the transmitting unit and arranged in a conformal material formed close to the shape of the upper jaw. The output unit composed of the transmitter and the sound signal receiving mechanism is configured in such a manner that the sound signal transmitting mechanism and the sound signal receiving mechanism can wirelessly transmit and receive sound signals. A space portion for providing a vibrating portion is provided in a central thickness portion of the conformal material, the bone conduction microphone is fixed to an inner wall of the conformal material, and the sound signal receiving mechanism is embedded in the conformal material. good. Further, a protrusion corresponding to the recess between the teeth is provided on the outer peripheral portion of the conformal material, and a hook portion capable of clamping the tooth portion is appropriately protruded on the outer peripheral portion of the conformal material, so that good. In the case of full dentures, etc., dentures can be mounted on the aforementioned conformal material. [Embodiment] An embodiment of the present invention will be described with reference to the drawings. Fig. 1 shows an embodiment of a bone conduction hearing aid according to the present invention. Fig. 1 is a vibration unit 5 formed by: a bone conduction microphone 2 and a receiving circuit 3; Instruction (Supplement) / 93-04 / 93100760 200417268 Conformal material 4 formed in a shape like this; the output portion is thus constituted, and the vibration portion 5 is buried in the central thickness portion of the conformal material 4. The conformal material 4 is made of the same resin as a common maxillary denture, and is formed into a shape closely to the maxilla. Since the central portion of the conformal material 4 can be relatively thick, the vibrating portion 5 can be easily buried there. In general, the vibrating portion 5 is provided with a space portion 8 in a central thickness portion of the conformal material 4, and the inner wall of the space portion 8 is filled by fixing the vibration plate 2a of the bone conduction microphone 2. The receiving circuit 3 may be embedded in the conformal material 4. On the periphery of the conformal material 4, there are provided protrusions 4a that can be fitted into the recesses between the teeth, and arbitrary protrusions 4a are provided with wire-like hooks 6 that can grip the teeth. The hook 6 that can grip the innermost second molar is configured to be larger than the others. The conformal material 4 is fixed to the upper jaw by using the hook 6 or using a denture stabilizer if necessary. When the user is all dentures, the dentures can be attached to the conformal material 4 by a usual method. In the receiving circuit 3, the transmitting section 7 for transmitting audio signals wirelessly can be carried in a pocket or the like by a user. The transmitting section 7 is provided with a microphone and a transmitting circuit for sound collection. The wireless transmitting / receiving mechanism can use a weak electric wave or an electromagnetic induction type of a loop antenna. According to this configuration, the sound signal transmitted from the transmitting section 7 is received by the receiving circuit 3, vibrates through the bone conduction microphone 2, and is transmitted from the teeth to the jawbone, and is heard through the hearing organ. sound. When using this bone conduction type hearing aid, the output unit 1 composed of the conformal material 4 having the vibration unit 5 can be fixed in a state of being closely attached to the upper jaw, and the transmitting unit 7 can be carried in a pocket or the like. The voices during the conversation can be picked up by 7 312 / Invention Specification (Supplement) / 93-04 / 93100760 200417268 The sound collecting microphone of the transmitting section 7 is received by the receiving circuit 3. The received sound is transmitted to the loudspeaker 2 to be converted into vibration and transmitted to the sound to be heard. (Effects of the Invention) The present invention is as described above. Since bone conduction is buried in the upper jaw denture, which is not visible from the outside, there is a risk of using a hearing aid, which is very suitable for hearing users. In addition, the bone-conducting loudspeaker has the effect of consuming teeth by direct tooth transmission, which can most effectively convey sound.
