摘要：
Devices for improving the quality of sound output by a speaker. For example, the device may act to remove ultrasonic frequencies from an audio signal prior to the audio signal being output by a speaker. In other examples, the device may act to impede the progress of harmonic distortion, intermodulation distortion, and environmental noise feeding back into the source device.
