ACOUSTIC CONVERTER DIAPHRAGM AND ACOUSTIC CONVERTER

摘要

It is possible to provide an acoustic converter diaphragm having characteristics such as a comparatively high heat radiation function, a comparatively high mold releasing property, a comparatively small lowest resonance frequency, and a comparatively large loss tangent. It is also possible to provide an acoustic converter using the acoustic converter diaphragm. The acoustic converter diaphragm (1) includes a base (11) and a damping layer (12) formed on one or both sides of the base (11). The damping layer (12) contains particles having the heat radiation function and has a comparatively high heat radiation function. The acoustic converterdiaphragm has a storage elastic modulus smaller than that of the base of the acoustic converter diaphragm. Moreover, the acoustic converter diaphragm has a loss tangent greater than that of the base of the acoustic converter diaphragm.
