Abstract

PURPOSE:To enable the radio transmission and reception for the bone transmission audio signal picked up, by incorporating the oscillation pickup, oscillator, electromagnetic induction type receiver and battery in the portable case mounted around the external ear. CONSTITUTION:The portable case 7 consists of the ear piece 7A, and ear hooking case 7B, and the oscillation pickup 1 picking up the bone delivered audio signal is built in the hollow of the ear piece 7A. The transmission system consisting of the amplifier 5 and oscillator 2, reception system of electromagnetic induction type receiver 4 consisting of the electromagnetic induction type coil 4A, amplifier 4B and speaker (including sound pressure earphone) 4C, and battery power supply 6 are built in the case 7B. The amplifier 5 is connected to the pickup 1 with the leads 3, and the speaker 4C is led to the sound path 11A via the sound leading tube 11. The case 7B is mounted at the back of ear shell as hearing-aid and the ear piece 7A is mounted on the external ear. Since the transmitter is mounted near the pickup, the collection of cord noise can be avoided.
