Description

TECHNICAL FIELD

On one aspect, the present disclosure relates to the field of multimedia playing, and particularly to a multimedia playing device.

BACKGROUND

The components of some existing multimedia playing devices, e.g., a smart TV set, have been integrated together, and the inventors of the disclosure have identified a number of problems in such an integrated multimedia playing device, for example:

None of the respective components of the multimedia playing device can be upgraded separately, and if one of the components in the multimedia playing device can not meet the requirement of its user, for example, function of a controller of the multimedia playing device can not meet the requirement of the user, then the entire multimedia playing device may be replaced, thus resulting in a serious waste of resources.

Moreover there is also such a growing demand of the user for the appearance of the multimedia playing device that the appearance thereof is typically expected to be more light-weighted and thinner as preferred, so the size of a speaker in the integrated multimedia playing device is typically so small that there is a poor sound effect of the multimedia playing device.

SUMMARY

The disclosure provides a multimedia playing device to reduce wasting of resources as a result of upgrading the multimedia playing device, and to improve a sound effect thereof.

An embodiment of the disclosure provides a multimedia playing device including an acoustic sub-system and a display sub-system connected with the acoustic sub-system, wherein:

the acoustic sub-system is configured to obtain some image data in a preset format according to one or more external devices' signals, and to transmit the image data in the preset format to the display sub-system; and to play an audio according to the one or more external devices' signals; and

the display sub-system is configured to display an image according to the image data in the preset format transmitted by the acoustic sub-system.

The multimedia playing device according to the embodiments of the disclosure includes the two components, i.e., the acoustic sub-system and the display sub-system, both of which can be upgraded separately, thus reducing the waste of resources as compared with the prior art; and the appearances of the two components can be designed separately so that the display sub-system can be made light-weighted and thin for a pleasing appearance thereof without compromising the size of the speaker in the acoustic sub-system so as to ensure the sound effect of the multimedia playing device.
