  • SECOND DEGREE OF FREEDOM SPEAKER FOR CAVITY RESONANCE CANCELLATION
    Publication number: 20240098404
    Abstract: A speaker produces acoustic frequencies within a housing that outputs the acoustic frequencies to a port. The produced frequencies travel through a cavity to the port which may have a cavity resonance that amplifies certain frequencies, affecting the frequency sensitivity of the speaker. To mitigate the cavity resonance, the speaker includes a membrane with regions having different breakup frequencies. One region is tuned to break up at a desired bandwidth of the speaker, and another region is tuned to break up at the cavity resonance, mitigating the distortion on frequency response due to the cavity resonance.

  • Esterified poly(vinyl acetal) resin compositions, layers, and interlayers having enhanced properties
    Patent number: 10428167
    Abstract: Resin compositions, layers, and interlayers comprising an acetoacetylized poly(vinyl acetal) resin are provided. Such compositions, layers, and interlayers can exhibit enhanced or optimized properties as compared to non-acetoacetylized poly(vinyl acetal) resins. The acetoacetylized poly(vinyl acetal) resins may be used in a layer or an interlayer for in an architectural application, or the acetoacetylized poly(vinyl acetal) resins may be used in a layer or interlayer, or combined with other layers, to provide an interlayer having good acoustic and other properties.

  • Cross-cancellation of audio signals in a stereo flat panel speaker
    Patent number: 9749750
    Abstract: A method of minimizing edge reflections of vibrational waves in a flat panel speaker assembly for a stereo device by characterizing the impulse response of the flat panel and associated components in response to a test signal to produce a cancellation signal, and applying the cancellation signal for each stereo channel to the opposing stereo channel.
