1. An electronic device comprising:
a speaker;
a temperature sensor disposed in at least some area inside the speaker; and
at least one processor,
wherein the at least one processor is configured to,
obtain a first temperature of the at least some area using the temperature sensor,
obtain a second temperature based on measuring impedance of a voice coil included in the speaker,
identify an operation state of the electronic device,
identify a weight of the first temperature and a weight of the second temperature corresponding to the operation state of the electronic device,
determine a temperature of the speaker based on the weight of the first temperature and the weight of the second temperature, and
based at least on the determined temperature of the speaker, change a function of the electronic device.
