Abstract
An acoustic device includes a detection unit configured to detect a timing to transition to each of a first power-saving mode and a second power-saving mode, a battery, a monitoring unit configured to monitor a remaining capacity of the battery, a signal processing unit configured to process a sound signal, a sound emitting unit configured to acoustically output the processed sound signal, a communication unit configured to transmit and receive a signal to and from a communication terminal and transmit the processed sound signal to the communication terminal, and a control unit configured to stop an operation of the signal processing unit based on the detection of the timing to transition to the first power-saving mode.
