Title:
ELECTRODYNAMIC TYPE PLANAR LOUDSPEAKER
Document Type and Number:
Japanese Patent JP2006050665
Kind Code:
A
Abstract:

To improve an electrodynamic type planar loudspeaker, and to provide a method for manufacturing the electrodynamic type planar loudspeaker.

The electrodynamic type loudspeaker typically includes a diaphragm, having a conductor applied to one of the surfaces. The diaphragm is secured to a frame. The conductor is connected to a power supply for providing electrical current via linear traces of the conductor that interact with magnetic fields generated by magnets that are mounted on 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 electrodynamic type loudspeaker.
