ACOUSTIC CONVERTER DIAPHRAGM, AND ACOUSTIC CONVERTER

摘要

Disclosed is an acoustic converter diaphragm having characteristics of relatively high heat radiation, relatively high mold releasability, relatively low minimum resonance frequency and relatively large loss tangent, and an acoustic converter having the acoustic converter diaphragm. The acoustic converter diaphragm (1) comprises a substrate (11), and a damping layer (12) formed on one or two faces of the substrate (11). The damping layer (12) contains particles having a heat releasing function and peelable from the substrate (11), so that the damping layer (12) has the relatively high heat radiation, the modulus of storage elasticity smaller than that of the substrate of the acoustic converter diaphragm, and the loss tangent larger than that of the substrate of the acoustic converter diaphragm.
