Abstract
Provided is a high-accuracy embedded audiphone. A transducer () made of a giant magnetostrictive element is provided in an intracorporeal unit () that is embedded in a skull (). An audible sound modulation transmission signal (S), which is amplitude-modulated by a sound collection signal generated in an extracorporeal unit (), is transmitted from an extracorporeal transmitter coil () to an intracorporeal receiver coil () provided in the intracorporeal unit () with the help of a transmission magnetic flux (). Moreover, because of an induced electromotive force of the intracorporeal receiver coil (), the transducer () expands and contracts. Therefore, it is possible to highly accurately conduct an audible sound signal through bone with no power source or demodulation circuit provided in the intracorporeal unit ().
