APPARATUS AND METHOD FOR MOMENTARILY DECREASING AUDIO VOLUME

摘要

Instantaneous and momentary interruption or decrease in audio volume is accomplished by interposing a phototransistor (40) in series in an audio circuit between an audio source (10) and an amplifier (32) and subsequently randomly moving a light blocking opaque object (61) over a window (42, 60) shielding the phototransistor from ambient light.
