Abstract: A speaker system includes: a portable speaker including a first locking member; and a charging base including a second locking member. The first locking member is configured to slide in: a first direction relative to the second locking member to lock the first and second locking members together; and a second direction, which is opposite to the first direction, relative to the second locking member to release the first locking member from the second locking member.

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.

Abstract: An audio device includes: a first detector configured to detect a volume of a first audio signal; and a low-frequency component adjuster configured to generate a second audio signal in which a level of a low-frequency component of the first audio signal is adjusted based on the volume detected by the first detector.

Abstract: A speaker structure includes a first enclosure, a second enclosure, a partition plate and a bass reflex port. The partition plate has a communication hole that is provided between the first enclosure and the second enclosure and allows the first enclosure and the second enclosure to communicate with each other. The bass reflex port is disposed at least on either the first enclosure or the second enclosure.
