Abstract:
A multifunctional electromagnetic transducer includes a bracket, a vibrating unit including a magnetic circuit part receiving in the bracket, and a plurality of elastic members assembled to the bracket for sustaining the magnetic circuit part. The magnetic circuit part defines a pole plate, a first magnet disposed at a center portion of the pole plate, and a plurality of second magnets surrounding the first magnet and forming a magnetic gap corporately with the first magnet. Each of the second magnets forms a receiving gap corporately with an adjacent second magnet. Each of the receiving gap receives a weight therein. A voice coil is partially inserted into the magnetic gap.
