Abstract

PURPOSE:To reduce thickness and permit easy assembling, parts exchanging, etc. by the constitution consisting of housing a vibration diaphragm affixed with a piezoelectric element into the hole of a module. CONSTITUTION:A hole 13 is formed in part of a module 3, and the under side of the hole 13 is sealed and waterproofed by a rubber packing 14. Lead conductors 15 project to the inner side of the hole 13 in an eaves shape, and a rubber ring 16 of an H shape in section is fitted freely removably to these. A vibration diaphragm 8 affixed with a piezoelectric element 7 on the top surface is freely attachable and detachable fitted to the inside circumferential side of the rubber ring 16. The vibration diaphragm 8 is easily detached from the under side of the hole 13. As a result, good assembling characteristic is obtained and the vibration diaphragm 8 affixed with the element 7 is easily exchanged independently.
