Claims

[Claims for Utility Model Registration] 1. A voice coil, a lower plate with a hollow center pole erected in the center, a ring-shaped magnet, and a ring-shaped plate stacked together to form a structure between the outer circumferential surface of the hollow center pole and the inner circumferential surface of the ring-shaped plate. a field portion forming a magnetic gap in which the voice coil is disposed; a housing portion housing the field portion; and a field portion formed integrally with the housing portion and suspending the voice coil within the magnetic gap. a first center suspension that elastically supports the first center suspension; a cushioning material that is adhered to the surface of the first center suspension that faces the ring-shaped plate; a second cylindrical driving body that is disposed so as to penetrate therethrough; a second cylindrical driving body that elastically supports the cylindrical driving body between the lower end of the cylindrical driving body and the housing part;
An electromechanical vibration transducer equipped with a center suspension. 2. A utility model registration claim characterized in that the second center suspension is a rubber-like elastic ring body that forms a flange at the lower end of the cylindrical drive body and is attached between the flange and the lower plate. An electromechanical vibration transducer according to scope 1.
