PURPOSE: To provide an assembly of a voice diaphragm and an inhalation valve with a reduced number of penetrating parts equipped on the face part, at the same time, with a small sized shape and remarkably improved voice transmission effect. CONSTITUTION: This voice diaphragm inhalation valve assembly comprises a valve main body 12 with a central opening part 20 and a valve seat part 26, a ring shaped valve member 28 supported movably against the valve seat part 26 of the valve main body 12, a spring 40 to attach the valve member 28 onto the valve seat part 26, and a voice diaphragm 44 supported by the valve member 28. The assembly is made so that the valve member 28 and the voice diaphragm 44 are moved and the valve member 28 leaves the valve seat part 26 by inhalation. |
