Abstract

PURPOSE:To make it possible to form easily a diaphragm of a good characteristic, by using mixture materials of flaky aluminum boride AlB2 and matrix resin. CONSTITUTION:If mixture materials of flaky aluminum boride AlB2 and matrix resin are used, a high-quality diaphragm for speaker where the sound propagation speed is high can be formed easily. As matrix resin, thermosetting resin (epoxy, polyester, etc.,) can be used. Further, since compound materials of the mixture materials above, synthetic resin, carbon fiber, etc., are uniform in Young's modulus and density in an arbitrary direction of fibers, a high-quality diaphragm can be obtained by using the compound materials above.
