ELECTROMAGNETIC TRANSDUCER

摘要

An electromagnetic transducer is disclosed. The transducer includes a bracket, a magnetic circuit part receiving in the bracket and having a weight, a voice generating part actuated by the magnetic circuit part for generating sound, the magnetic circuit part sandwiched by two spring-plates for vibrating along a direction. The weight further includes a plurality of supporting protrusions for anchoring the two spring-plates, respectively. Each of the two spring-plates has a ring plane lamina and two helical wound springs extending inwardly from the ring plane lamina.
