ELECTROMAGNETIC TRANSDUCTION ACOUSTIC BRIDGE AND RELATED METHODS

摘要

An electromagnetic transduction acoustic bridge appliance may include an electro-acoustic transducer including a housing, and a coil carried by the housing, and a piezoelectric paste adjacent the electro-acoustic transducer and including metallic powder embedded therein for picking up audio information of a magnetic field lost from the coil. The electromagnetic transduction acoustic bridge appliance may include a link coupling the piezoelectric paste to the housing. The piezoelectric paste may form an acoustic bridge for picking up the audio information and transmitting the audio information to the housing using the link.
