Sonic transducer mounting
First Claim
1. A sonic transducer system for transmitting sonic signals in a medium comprising:
- a sonic transducer which is sheet-like and rigid and substantially incapable of flexural and diaphragm-like movement, said transducer having a front sonic energy-transmitting surface and a rear surface,said transducer comprising piezoelectric sonic energy generating means having opposed generally planar electrodes, sonic energy transmitting means which is sheet-like and rigid and substantially incapable of flexural and diaphragm-like movement, coupling means coupling said generating means to said transmitting means with said electrodes of said generating means oriented principally parallel to the general plane of said sheet-like transmitting means, and means for damping the natural resonant frequencies of said transmitting means,means for supporting said transducer, andresilient mounting means interposed between said transducer and said supporting means and secured to both said transducer and said supporting means.

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.
