ABSTRACT:
Electric circuitry to correct for spurious sound pressure responses of audio transducers is disclosed. In particular, electric circuitry to compensate for "pre-shoot" of an audio transducer system is disclosed. The circuitry includes a delay line electric circuit carrying the bulk of the electric signal energy to the audio transducers and a parallel circuit to feed forward in real time an electric signal replica of diminished amplitude to the audio transducers. The replica thereby cancels or greatly minimizes the "pre-shoot" or prior undesired significant sound pressure responses of the audio transducers. The circuits include, in combination with the feed forward circuit, additional circuitry to counteract subsequent undesired significant sound pressure amplitude responses such as resonance (ringing). The new circuits utilize series resonant circuits in parallel to ground with the audio transducers as the preferred means to counteract the subsequent undesired sound pressure responses.
