本発明は、外耳道で骨伝導音声をピックアップする装置
及びこれを利用した通話装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a device for picking up bone conduction sound in an external auditory canal, and a communication device using the same.
従来、鉱山の採炭・採石現場、空港、建設現場あるいは
板金工場等の騒音場所で音声伝達を行うには、単一指向
性マイクロホンを口唇で用いる方法、加速度型振動ピッ
クアップを咽頭部や前額部で用いる方法などが多く用い

騒音の除去に限界があり、騒音の激しい場所には不適当
であるし、後者の方法は咽頭部や前額部で振動ピックア
ップを密着固定する必要があるため、その取付けが複雑
または面倒であり、かつ不体裁となるばかりでなく、装
着者の使用上の違和感、不快感が著しく長時間の使用に
耐え得ないと言う不都合があった。Conventionally, to transmit voice in noisy places such as coal mining and quarrying sites, airports, construction sites, and sheet metal factories, the conventional methods have been to use unidirectional microphones on the lips, and to use accelerometer vibration pickups on the pharynx or forehead. However, the former method, which uses a unidirectional microphone, has a limited ability to remove external noise and is unsuitable for noisy locations, while the latter method uses a unidirectional microphone that removes noise from the pharynx and forehead. Because it is necessary to tightly fix the vibration pickup at the part, the installation is complicated or troublesome, and not only is it unsightly, but it also causes discomfort and discomfort to the wearer, making it difficult to withstand long-term use. There was an inconvenience that there was no such thing.
そこで、本願出願人は特公昭53−39763号にて耳
の外耳道に挿入する筒状殻体をなすイヤーピース内に、
作動方向が外耳道の方向と略々直角方向の振動ピックア
ップを設けて、外耳道壁から骨伝導音声振動をピックア
ップする装置を提案した。Therefore, in Japanese Patent Publication No. 53-39763, the applicant of the present application has incorporated a cylindrical shell into an earpiece to be inserted into the external auditory canal of the ear.
We proposed a device that picks up bone-conducted sound vibrations from the wall of the external auditory canal by installing a vibration pickup whose operating direction is approximately perpendicular to the direction of the external auditory canal.
しかしながら、上記のピックアップ装置では、筒状殻体
をなすイヤーピースは外耳道に十分深く挿入されていな
いと安定保持は難しい。そこで、イヤーピースを十分に
挿入すると、外耳道との接触面積及び接触圧が増大して
機能の向上のためには好ましいが、イヤーピースが外耳
道に密着し過ぎてかえって違和感・不快感が生じる。ま
た、人によっては接触圧が高くなり過ぎて圧迫感や外耳
道入口部さえもつようになる。However, in the above-mentioned pickup device, it is difficult to stably hold the earpiece, which is a cylindrical shell, unless it is inserted sufficiently deeply into the external auditory canal. Therefore, if the earpiece is fully inserted, the contact area and contact pressure with the ear canal will increase, which is desirable for improving function, but the earpiece will come into too close contact with the ear canal, causing discomfort and discomfort. In addition, for some people, the contact pressure becomes too high, causing a feeling of pressure or even the entrance of the ear canal.

The earphone section transmits the sound as air pressure vibrations through the sound conduit to the ear canal. In this way, a call can be made using the microphone section and the earphone section.
以下、添付図面にもとづき本発明の詳細な説明する。 Hereinafter, the present invention will be described in detail based on the accompanying drawings.

This holding force is set so that the microphone part 2 can be slid in its longitudinal direction, that is, toward the external auditory canal, for position adjustment, and can be reliably held at an appropriately adjusted position. This is possible by appropriately setting the friction coefficient between the vibration absorbing material 13 and the cylindrical shell 21 and the elastic force of the vibration absorbing material 13.

It may also be covered with a vibration absorbing material 268. Even in this case, as in the first embodiment, the vibration absorbing material 26A can generate an appropriate coefficient of friction and elastic force for positioning between the vibration absorbing material 26A and the mounting portion 1.

The device of this embodiment is characterized in that an earphone section 3 is built into the mounting section of the pickup device of the first embodiment shown in FIG. The earphone section 3 itself may be of a publicly known type, and emits sound from a sound conduit 31 by converting signals received from the outside through a transmitter/receiver 30 into air vibrations. Sound is sent to the ear canal. In this case as well, the vibration absorbing material functions to prevent vibrations on the earphone section 3 side from being transmitted to the microphone section 2. Thus, according to the device of this embodiment, in response to the voice from the other party through the earphone section 3, the voice is transmitted to the other party via the microphone section 2, and can be used as a telephone communication device.
