    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.
