Panel-form loudspeakers










Image Number 4 for United States Patent #6198831.

A panel form loudspeaker/microphone combination has a distributed resonant bending wave member and two transducers mounred on the member at sites where the number of vibrationally active resonance anti-nodes is relatively high. One transducer is capable of vibrating the member to couple to and excite resonant bending wave modes in the member and cause the member to produce an acoustic output. The other transducer also is capable of coupling to he resonant bending wave modes in the member, but it produces an output signal in response to resonance of the member due to incident acoustic energy. The combination may be part of a loudspeaker system including an amplifier for the source signal coupled to the first transducer, and a signal receiver coupled to the second transducer for treating the output signal.
