发明名称 Dual coil drive with multipurpose housing
摘要 An improved electromagnetic transducer able to produce more power per mass than a conventional transducer. This increased power per mass is made possible by combining a properly designed housing, a neodymium magnet and a dual coil structure. This design dissipates the heat generated by the transducer, increasing the efficiency and power of the transducer. Also, by dissipating heat more efficiently, the transducer can be made smaller and more powerful than conventional transducers.
