Muting apparatus in car audio system |
摘要 |
A muting apparatus can mute sounds when a voltage drops even in a car audio system in which a digital audio signal is transmitted between audio components units. In the apparatus the drop of the voltage supplied to each of the audio component units is detected in each of the audio component units and, when the drop of the voltage is detected in any one of the audio component units, an analog audio signal is muted immediately before it is converted into an acoustic energy.
