Claims

[Scope of utility model registration request]

(1) Two disc-shaped magnets, each magnetized with different magnetic poles in the center and outer periphery, are stacked so that the same poles face each other, and a spiral shape is formed on both sides of the vibrating membrane made of electrically insulating film. In an electroacoustic transducer in which a diaphragm formed with a conductor is held between its magnets, a tongue piece is integrally formed on the periphery of the diaphragm to form a terminal part, and an external connection is made on the surface of the terminal part. a connecting terminal is formed, the outer end of the conductor is extended onto the surface of the terminal portion to be electrically connected to the connecting terminal, and the periphery on both sides of the vibrating membrane is coated with an electrically insulating material to form an integral An electroacoustic transducer characterized in that the diaphragm is configured as follows.

(2) The electroacoustic transducer according to claim 1, wherein the vibrating membrane is applied with tension in the diametrical direction and is held between the magnets.

(3) The electric power according to claim 1 or 2, wherein the vibrating membrane is electrically connected to the spiral conductors formed on both sides by through-hole plating at the center. acoustic transducer.
