Abstract
PURPOSE:To expand a piston motion region by increasing primary resonance frequency by strengthening the rigidity of the entire diaphragm, by forming a surface material of a material composed principally of carbon. CONSTITUTION:On both the sides of hollow diaphragm 1 using a coil in a honeycomb shape, etc., surface materials 2 and 3 are bonded which are a kneaded mixture of plastics such as vinyl chloride and graphite. Consequently, the rigidity can be increased several times as high as that of aluminium.
