Abstract
An audio device including: an audio signal input section that receives an audio signal; a signal processor that performs signal processing on the audio signal; an amplifier that amplifies the audio signal; an audio signal output section that outputs the amplified audio signal; a feeder that feeds electric power to an external device; a feed detector that detects a state of feeding of the electric power by the feeder; a controller that causes the signal processor to perform level limiting processing to limit a level of the audio signal in a case where the feed detector detects that the feeder is feeding the electric power to the external device.
Claims20
An audio device comprising:
- an audio signal input section that receives an audio signal;
- a signal processor that performs signal processing on the audio signal;
- an amplifier that amplifies the audio signal;
- an audio signal output section that outputs the amplified audio signal;
- a feeder that feeds electric power to a secondary battery that is not part of the audio device;
- a feed detector that detects a state of feeding of the electric power by the feeder;
- and
- a controller that causes the signal processor to perform level limiting processing to limit a level of the audio signal in a case where the feed detector detects that the feeder is feeding the electric power to the secondary battery.
An audio signal processing method comprising:
- receiving an audio signal;
- performing, by a signal processor, signal processing on the audio signal;
- amplifying the audio signal;
- outputting the amplified audio signal;
- feeding, by a feeder, electric power to a secondary battery that is not part of the audio device;
- detecting, by a feed detector, a state of feeding of the electric power by the feeder;
- and
- causing the signal processor to perform level limiting processing to limit a level of the audio signal in a case where the feed detector detects that the feeder is feeding the electric power to the secondary battery.
