The sound emitted from the sound guide tube (3) enters the ear, so if the sound guide tube (3) bends in the middle, it becomes difficult to hear. There is a problem that it is easy to pick up (and noise).Furthermore, the parts (speakers) are dangling in the middle of the cord, which is a nuisance.

が向上する。The sound emitted from the speaker installed in the shell reaches the eardrum through the sound hole of the shell, but the propagation is not hindered on the way, and since the speaker is located close to the eardrum, the sound from the speaker reaches the eardrum. There is no sound attenuation and the clarity of the sound is improved.

及びスピーカー５と送受信機とを接続する電線である。An embodiment of the present invention will be described with reference to FIGS. 2 and 3. In the figures, reference numeral 1 denotes a shell usually made of plastic, and the distal end 2 has a shape that allows it to be inserted tightly into the external auditory canal 3. A speaker 5 and a pickup device (&4) are built into the part exposed outside the ear. 6 is a sound hole formed from the speaker 5 to the tip a of the shell 1; A duct 7 that communicates with the shell 1 is provided to merge with the sound hole 6 or separately from it.The pickup mechanism 4 picks up the speaker's own bone conduction sound signal (vibration) that is transmitted to the wall of the ear canal 3. It consists of a sensing section that senses, and a vibration pickup element that converts the vibration sensed by the sensing section into an electrical signal.The vibration pickup element includes:
Usually piezoelectric elements are used. 8 is a pickup mechanism 4
and an electric wire connecting the speaker 5 and the transmitter/receiver.

鼓膜に達するので、ノイズが混入したりすることがなく
、明瞭に聴取できることになる。なお、ピックアップ機
構４の方は、従来のものと同様の作用をする。In this configuration, the sound emitted from the speaker 5 reaches the eardrum directly from the sound hole 6 without passing through the conventional sound guide tube, so it can be heard clearly without noise being mixed in. . Note that the pickup mechanism 4 operates in the same manner as the conventional one.

いった効果がある。Effects of the Invention As described above, the present invention incorporates a pink-up mechanism and a speaker in one shell, thereby avoiding noise contamination caused by the sound guide tube and attenuation of sound from the speaker. It is possible to improve the clarity of sound, and because the number of parts is small, it is suitable for mass production.
