ABSTRACT:
A speaker in which the inner peripheral face of a ring-shaped soft ferrite core is cemented to a cylindrical projection extending from a lower portion of a bowl-shaped frame. An outer peripheral surface of a co-axially disposed ring-shaped bond magnet is fitted into a recess of the frame. Two magnetic gaps are formed between facing surfaces of the ring-shaped bond magnet and the ring-shaped soft ferrite core. Two voice coils are mounted on a cylindrical bobbin and suspended from a vibratory diaphragm such that the voice coils are inserted into the magnetic gaps.
