ELECTROACOUSTIC TRANSDUCER FOR HEARING AID COMPATIBILITY AND COMMUNICATIONS DEVICE COMPRISING THE SAME

摘要

An electroacoustic transducer for hearing aid compatibility and a communication device comprising the same are provided to enable a user wearing a hearing aid to more clearly recognize a voice by supporting an auxiliary coil to operate at an induced coil through magnetism. In an electroacoustic transducer(110) for hearing aid compatibility, a protector(150) has a plurality of sound discharging holes. A frame supports the outer frame of the protector(150), and forms a predetermined inner space with the protector(150). A diaphragm is supported by the frame, and generates sound by vibration. A voice coil is mounted to the lower end of the diaphragm. A magnet is mounted to the frame corresponding to the voice coil. An upper plate supports the magnet together with the frame by being formed at the upper part of the magnet. An auxiliary coil(140) is formed at the outside of the frame. The auxiliary coil(140) forms a magnetic field corresponding to an induction coil of a hearing aid, and is supported by a magnetic body.
