Acoustic Transducer

摘要

An acoustic transducer (104) is shown, which may be configured as either a loudspeaker or a microphone. The acoustic transducer includes a magnet system (401), and a diaphragm (303) having a conductive element (402) disposed on it. The conductive element has a first outer conductive portion (405) and a second outer conductive portion (407) for generating force parallel to the magnet system. It also has a central conductive portion (406) for generating force normal to the magnet system. In this way, application of an audio frequency signal to the conductive element, possibly via positive and negative input terminals (202, 203), causes oscillation of the diaphragm.
