Abstract
Disclosed is an output device that outputs an audio signal. An output device which outputs an audio signal includes a battery, a sensing module including a plurality of sensors, a communication circuit configured to communicate with at least one of an external electronic device and another output device coupled to the output device, and a processor electrically connected with the battery, the sensing module, and the communication circuit. The processor is configured to obtain information about a level of the battery, to obtain information about a level of another battery included in the another output device using the communication circuit, and to assign a task associated with one of the plurality of sensors to the output device and/or the another output device based on the information about the level of the battery and the information about the level of the another battery.
