Characteristic of Loudspeaker by a Multilayer Piezoelectric Ceramic
This paper presents construction and characteristics of a small size loudspeaker with a multilayer piezoelectric ceramic bimorph diaphragm for a mobile telephone use. The multilayer ceramic wafer is characterized by lower operation voltage due to lager capacitance than it of conventional ceramics. This is suitable for mobile equipment with a battery operation. Precise measurement of diaphragm parameters and analysis of loudspeaker response are described in this paper.
