Bone Conduction Transducer

A. General Description

Most of what we hear is due to sound waves traveling through the air. Sound waves travel

through the outer and middle ear before arriving at the cochlea in the inner ear. Sound waves can

also get to the cochlea through direct vibration of the bones in the head.

Bone conduction is the conduction of sound to the inner ear through the bones of the skull.

Bone conduction products have following advantages over traditional headphones:

1.Ears-free, thus providing extended use comfort and safety

2.No electromagnetic waves (EMW), eliminating the potential effect of EMW on cerebrum (if

any)

3.High sound clarity in very noisy environments, can be used with hearing protection

4.Can have the perception of stereo sound

Bone conduction Transducers (BCT) is an electro-mechanical device, which directly convert

the electric signal to mechanical vibration. BCT can be used for sound generator for mobile device

such as MP3, headphone, Bluetooth, mobile phone and table vibration speakers.

The BCT transducer is the new world standard in mobile device for sound generation. . It

delivers accurate broadband sound output to the users. . Prepare to discover a new dimension of

sound. The BCT transducer creates sound through vibration transfer instead of pressuring the air

around you. The audio signal is delivered so cleanly that the brain interprets the stimulus as

Sound.
