{"product_id":"bone-conduction-kit-discontinued","title":"Bone Conduction Kit [discontinued]","description":"\u003cp\u003eBone conduction is a method of sound transmission. The sound is converted into different frequencies of mechanical vibration and transmitted through the human skull, bone labyrinth, inner ear lymphatic transmission, helix, auditory nerve and auditory center.\u003c\/p\u003e\n\u003cp\u003eThis kit is composed of a bone conduction speaker, a speaker driver board and accessories. The kit is intended to help understand the principles of bone conduction technology, making hearing aids or bone conduction headphones.\u003c\/p\u003e\n\u003cp\u003eThe speaker driver board is designed based on MAX9814 microphone amplifier and PAM8406 amplifier, high sensitivity and suitable for 3.6v-4.2v lithium battery power supply.
