ABSTRACT:
A sonic transducer incorporating a rigid plate-like transmitting member coupled to electromechanical compression wave generating means such as a piezoelectric crystal for transmitting sonic energy in a medium. The transmitting means is damped to prevent ringing, and the transducer is particularly responsive to the high frequency audio spectrum. The sheet-like configuration of the transducer enables it to be recessed within a generally flat panel such as a front panel of a speaker cabinet while nevertheless being separated from the inside of the cabinet to avoid interaction with a conventional cone-type speaker that may be mounted in the same cabinet. The sheet-like transducer is resiliently mounted in a direction contrary to the principal direction of sonic energy propagation in the transducer to minimize loss of sonic energy to supporting structure such as a speaker cabinet.
