Abstract

PURPOSE:To obtain a good-appearance sounding body for analog alarm by using a transparent piezoelectric ceramic of such a composition that it is provided with a windshield glass and a transparent piezoelectric ceramic-metallic case having a transparent exciting electrode and that the transparent electrode is directly connected to the metallic case, etc. CONSTITUTION:The transparent electrode 1a is tightly attached onto reverse side of the windshield glass 1, and the driven electrode 2b is also tightly attached onto reverse side 2' of the transparent piezoelectric ceramic 2. And the top surface 2a of the transparent piezoelectric ceramic 2 is fixed onto reverse side of the windshield glass 1 in a coaxially circular form with a thin bonding material, and the transparent electrode 1a is directly connected to the step 3a of the matallic case 3 electrically and mechanically when the windshield glass is inserted. On the other hand, a part of the metallic case 3 is provided with a groove 3a', in which a thin plate spring 6 is fixed through an insulating member 5, and a connecting terminal 6a protrudes. This width may safely be made narrower as far as electrical connection is possible. It is possible, by using such a simple structure, to obtain a good-appearance sounding body for analog alarm.
