Diaphragm Parameters and Radiation Characteristics of Multilayer Piezoelectric Ceramic Loudspeakers
This paper presents diaphragm parameters and analysis of radiation characteristics for small size loudspeaker by a multilayer piezoelectric ceramic bimorph diaphragm. The multilayer ceramic wafer is suitable for buttery operated mobile phones because of its lower electrical impedance nature. Three diaphragm parameter measuring methods are compared to develop the optimum measurement of diaphragm parameters. Then, output sound pressure frequency characteristics of a loudspeaker model with actual acoustical loads are analyzed.
