Description

Bone Conduction Kit

Bone conduction is a way of sound transmission. The sound is converted into different frequencies of mechanical vibration, and transmitted through human skull, bone labyrinth, inner ear lymphatic transmission, helix, auditory nerve, auditory center.

This kit is composed by a bone conduction speaker, a speaker driver board and other kinds of accessories. This kit is intended to help understand the principles of bone conduction technology, making hearing aids or bone conduction headphones.

The speaker driver board is designed based on MAX9814 microphone amplifier and PAM8406 amplifier, high sensitivity, suitable for 3.6v-4.2v lithium battery power supply. It comes with a potentiometer which has power switch function, easy to control.
