Working Principle of Bone Conduction Vibrator:
Piezoelectric Bone Conduction Vibrator, is composed by multi-layer piezoelectric ceramic sheet and a piece of metal substrate. When the excitation signal is applied to the multi-layer piezoelectric ceramic plate, the vibration plate generates vibration, and the vibration is transmitted through solid materials, such as human skull and auricle cartilage, directly to the cochlea, so as to achieve the sound transmission effect.
Features of Piezoelectric Vibrator
Compact size,light weight
Low power consumption
Excellent sound quality
Nonmagnetic and nonradiative
To achieve high quality communication in a noisy environment
Protect hearing, Healthy
The piezoelectric plate used for bone conduction adopts laminated structure, adjust the single layer thickness and lamination number, which can adapt to different driving voltage.
Scope of applications of Piezo Sound Element
Bone condition hearing aids
Bone condition blue tooth
Mobile phone receiver or speaker
Bone condition smart watches
Bone condition headphones or headset
Bone condition glasses and other wearable devices
