DIAPHRAGM FOR PLANAR SPEAKER AND PLANAR SPEAKER

摘要

There is provided a highly reliable diaphragm of a planar speaker exhibiting long term stability and ensuring flat sound pressure frequency characteristics. A planar speaker is also provided. The diaphragm (1) for a planar speaker comprises a voice coil (2) formed by winding a linear conductor, two adhesive layers (3, 3') sandwiching the voice coil (2), and substrates (4, 4') stuck to the two adhesive layers (3, 3') on the side opposite to the voice coil (2). The planar speaker employs that diaphragm.
