Patent ID: 10334367

Abstract:
There is provided an electroacoustic transducer capable of reproducing high-quality sound particularly in a low frequency range, including: a cylindrical yoke; a drive magnet placed coaxially with the yoke so as to circumferentially face the yoke; a diaphragm fixed at the cylindrical tip end portion of the yoke so as to face each other; and a voice coil fixed to one surface of the diaphragm, wherein the diaphragm is formed, with the central region having rigidity so as to be less flexible compared with an outer circumferential region surrounding the central region, and the voice coil is inserted between the drive magnet and the yoke, and configured to cause the diaphragm to vibrate by a voice signal applied to the both-end lead wire. The both-end lead wire of the voice coil is led out to the outside through the central region of the diaphragm.
