Abstract: A detachable display device includes a main box including a microphone and a main processor, and a display including an amplifier configured to amplify an audio signal received from the main processor and a speaker configured to convert the amplified audio signal into a sound and output the sound. The main processor is configured to perform acoustic echo cancellation (AEC) on the audio signal based on the audio signal output by the main processor, equalization information, and volume information.
