Abstract
A Tonpilz transducer which includes a first stack of piezoceramic elements with a first plurality of electrodes connected to form a first pair of external connections. There is also a second stack of piezoceramic elements with a second plurality of electrodes connected to form a second pair of external connections, and the first and second stacks of piezoceramic elements have opposed polarizations.
Claims1
In a Tonpilz transducer comprising a first stack of piezoceramic elements with a first plurality of electrodes connected to form a first pair of external connections, wherein the improvement comprises a second stack of piezoceramic elements with a second plurality of electrodes connected to form a second pair of external connections, and said first and second stacks of piezoceramic elements have opposed polarizations, such that the opposing polarization make it possible to drive the transducer with a push-pull amplifier.
