Abstract
An electroacoustic transducer is provided that combines the properties and advantages of the known concepts of the thickness mode transducer and of the bending transducer with each other. For this purpose, an electroacoustic transducer is provided, which includes a housing and an oscillating structure. The oscillating structure is formed by at least one piezoelectric element, a diaphragm, and an acoustic transmitter. It is provided that the diaphragm is designed as a bending transducer, and the acoustic transmitter is designed as a thickness mode transducer.
