Title:
ELECTRODYNAMIC TYPE PLANAR LOUDSPEAKER
Document Type and Number:
Japanese Patent JP2006054917
Kind Code:
A
Abstract:

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

The electrodynamic type speaker typically includes a diaphragm having a conductor applied to one of surfaces. The diaphragm is secured to a frame. The conductor is connected to a power supply for supplying an electrical current through linear traces of the conductor that interact with magnetic fields generated by magnets that are mounted to the frame. The diaphragm is driven by a motive force created when a current passes through the conductor within the magnetic field. The electrical current is varied to create an acoustical output from the electrodynamic type speaker.
