Title:
ELECTRO-DYNAMIC PLANAR LOUDSPEAKER
Document Type and Number:
Japanese Patent JP2006060851
Kind Code:
A
Abstract:
To provide a method for improving and manufacturing an electro-dynamic planar loudspeaker.
The electro-dynamic loudspeaker typically includes a diaphragm having a conductor applied to one of its surfaces. The diaphragm is secured to a frame. 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 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.
