The disclosure relates to a content reproducing electronic apparatus. The disclosure more particularly relates to an electronic apparatus outputting an audio signal of a content at a volume based on a state of an external electronic apparatus located around the electronic apparatus.
In a related art content reproducing electronic apparatus, it might be difficult to effectively provide a sound of a content to a user, if an ambient noise is comparatively large.
In order to solve such a problem, an electronic apparatus including a microphone for measuring a noise and adjusting a volume of a voice of a content by considering the measured noise via the microphone has been developed.
However, in the related art electronic apparatus which does not include the microphone, it is difficult to execute automatic volume adjustment by considering the noise.

In accordance with an aspect of the disclosure, there is provided a content reproducing electronic apparatus including a communicator including circuitry, an audio output device, and a processor configured to receive state information indicating a state of an external electronic apparatus from the external electronic apparatus located around the electronic apparatus via the communicator, obtain noise information corresponding to the received state information, and control the audio output device to output an audio signal of a content based on a volume corresponding to the obtained noise information.
In accordance with an aspect of the disclosure, there is provided a method for controlling a content reproducing electronic apparatus, the method including receiving state information indicating a state of an external electronic apparatus from the external electronic apparatus located around the electronic apparatus via a communicator, obtaining noise information corresponding to the received state information, and outputting an audio signal of a content based on a volume corresponding to the obtained noise information.

The volume setting history corresponds to a history in which volumes of audio signals of the contents output by the audio output device 120 are set by a user command. The user command herein may be received from an apparatus for controlling the electronic apparatus 100 such as a remote control, or a smartphone or a set-top box installed with a remote control application, via the communicator 110. In addition, the user command may be input via a user input device or a user input unit 150 of the electronic apparatus 100 (see

The above example is an embodiment of the volume setting history corresponding to the state of the external electronic apparatus according to the received state information, but the volume setting history corresponding to the noise level according to the obtained noise information may be used.
For example, a history, in which the volume is set to “5” by the volume setting of a user in a state where the noise level of the obtained noise information is 5 dB, may be assumed. If the noise information corresponding to the noise level of 5 dB is obtained again later, the processor 130 may identify the optimal volume corresponding to the obtained noise information as “5”.
If it is determined that there is no volume setting history corresponding to the state of the external electronic apparatus according to the received state information, the processor 130 may identify the volume corresponding to the obtained noise information among the volumes predetermined for each noise information as shown in
The processor 130 may directly identify the optimal volume by using the volume predetermined for the state of the external electronic apparatus corresponding to the received state information.
