ELECTRO-DYNAMIC PLANAR LOUDSPEAKERS

摘要

Electro-dynamic loudspeaker (100) typically includes a diaphragm (104) having a conductor (106) applied to one of its surfaces. The diaphragm is secured to a frame (102). The conductor is connected to a power supply for providing electrical current through linear traces of the conductor that interact with magnetic fields generated by magnets (202) that are mounted to the frame. The diaphragm is driven by a motive force created when current passes through the conductor within the magnetic field. The electrical current is varied to create an acoustical output from the electro-dynamic loudspeaker.
