Abstract

PURPOSE:To enable to detect the audio with fidelity, by constituting the oscillation pick up with the pick up detecting the oscillation of the frontal bone and that detecting the oscillation of the lower jawbone, making broad the frequency range of detected audio frequency and making less the effect of external noise. CONSTITUTION:The bone conduction type oscillation pick up unit is constituted with the first oscillation pick up 1a and the second oscillation pick up 1b, the pick up 1a is mounted on the frontal bone 4, the pick up 1b is mounted on the lower jawbone 5, and the detection signal of the picks up 1a, 1b is inputted to the mixing amplifier 3 via the lead wire 2. Further, the high tone part of audio signal is mainly conducted with the pick up 1a, and the lower tone of audio signal is conducted with the pick up 1b, the output of the both picks up 1a, 1b are synthesized with the amplifier 3, the overall frequency band is made broad to detect the audio with fidelity and to make less the effect due to noise.
