PURPOSE:To attain flat frequency characteristic, high elasticity, high loss and ease of manufacture by constituting a diaphragm for speaker with a composition comprising a denatured polyolefin, a flaky graphite and carbon fibers. CONSTITUTION:In constituting the composition of the diaphragm for speaker, the polyolefin denatured by an unsaturated carboxylic acid and/or its derivative, the flaky graphite and carbon fibers are mixed. The flat frequency characteristic is obtained by forming uniformly the total of the flaky graphite and carbon fibers to 5-70wt% of all the components. |
