Abstract: A display device includes at least one speaker, a signal transceiver and a processor. The at least one speaker outputs a sound according to a volume parameter. The signal transceiver receives incoming call information from a communication device. The processor is electrically coupled to the at least one speaker and the signal transceiver. The processor detects signal strength of the communication device and adjusts the volume parameter according to the incoming call information and the signal strength, in order to increase or decrease a volume of the sound.
