ABSTRACT:
The invention provides an electroacoustic transducer capable of efficiently carrying out conversion from electric signals to sound or from sound to electric signals at low distortion, which requires no special shape nor processing as a magnet, requires no minute setting of the magnetization direction, and sets a distribution of higher magnetic flux densities for effective action with respect to an electric conductor of an acoustic diaphragm than in a magnet plate magnetized in the radius direction although the production process thereof is remarkably simple as in a magnet plate magnetized in the radius direction.
