A display device according to an embodiment disclosed herein may include: a microphone for receiving an audio signal; a controller for determining whether the audio signal is an alarm signal; and a speaker for outputting a signal corresponding to the alarm signal. A display device according to an embodiment disclosed herein may include a display for outputting a signal corresponding to an alarm signal. ## Claims ### Claim 1 A display device comprising: a microphone receiving an audio signal; a controller determining whether the audio signal is an alarm signal; and a speaker outputting a signal corresponding to the alarm signal, wherein the controller: extracts a music signal from the received audio signal, and registers the extracted music signal as an alarm signal based on the extracted music signal being received at a predetermined time or at a predetermined period. ### Claim 2 (depends on 1) The display device of claim 1, further comprising: a display outputting a signal corresponding to the alarm signal. ### Claim 3 (depends on 2) The display device of claim 2, wherein the controller recognizes a trigger signal added to an alarm signal among the audio signals and outputs a signal corresponding to the trigger signal. ### Claim 4 (depends on 3) The display device of claim 3, wherein the trigger signal is connected to and added to an end portion of the alarm signal. ### Claim 5 (depends on 3) The display device of claim 3, wherein the controller recognizes the trigger signal and generates a control signal corresponding to the trigger signal to drive at least one of the speaker or the display. ### Claim 6 (depends on 3) The display device of claim 3, wherein the controller recognizes the trigger signal, generates a control signal corresponding to the trigger signal, and transmits the control signal to a peripheral device. ### Claim 7 (depends on 2) The display device of claim 2, wherein when an alarm signal is recognized, the controller displays a QR code or barcode on the display and provides connection to a user device. ### Claim 8 (depends on 2) The display device of claim 2, wherein when an alarm signal is recognized, the controller generates a control signal set corresponding to the recognized alarm signal and drives at least one of the speaker or the display. ### Claim 9 (depends on 1) The display device of claim 1, wherein the audio signal received by the microphone includes a voice signal and a music signal, and wherein the controller determines whether the received music signal is an alarm signal. ### Claim 10 (depends on 1) The display device of claim 1, wherein the controller: registers the extracted music signal as an alarm signal, for the extracted music signal, based on at least one of a similarity comparison value with a music signal stored in a database, a reception time coincidence comparison value, or a reception period comparison value satisfying a preset criterion. ### Claim 11 (depends on 10) The display device of claim 10, wherein a music signal that is not received again until a certain period of time has elapsed among the music signals registered as the alarm signals is released from the registered alarm signal. ### Claim 12 (depends on 1) The display device of claim 1, wherein the audio signal is generated from a device located around the microphone. ### Claim 13 (depends on 1) The display device of claim 1, wherein the controller outputs an audio signal or a video signal to inquire whether to register an alarm based on an alarm signal being recognized. ### Claim 14 (depends on 1) The display device of claim 1, wherein when an alarm signal is recognized, the controller transmits a control signal set corresponding to the recognized alarm signal to a peripheral device.
