ABSTRACT:
A sound transducer having a high impedance relative to air is coupled with mechanical transformers. The output transformer is in the shape of a dish having the center coupled to a piezoelectric transducer, the outer portion of the dish is unsupported and more flexible than the center section at resonance this allows large amplitude movement and a better impedance match to air.
