A Novel Dentary Bone Conduction Device Equipped with Laser Communication in DSP
In this study, we designed a dentary bone conduction system that transmits and receives audio by laser. The main objective of this research was to propose a complete hardware design method, including a laser audio transmitter and receiver and digital signal processor (DSP) based digital signal proce...
