Patent abstract
A capacitive touch switch system for use in an audio application includes a detecting circuit with a capacitive sensing device and a filtering circuit. The capacitive sensing device senses changes in capacitance. The filtering circuit filters external and/or internal interference that may affect the sensing of a capacitance change and/or the sound quality of an audio device. The capacitive touch switch system may be incorporated into a speaker and/or other components of the audio device. The capacitive touch switch system may control various audio parameters such as volume, bass, treble, balance, channel, and the like.
