Abstract

The present invention relates generally to a structure of coupling a speaker to a media playback device, such as a set-top box, an audio player, and a video player. More particularly, the present invention integrally combines a speaker block equipped with a multi-channel speaker and a playback module block equipped with a media playback module through a docking interface, in order to overcome the disadvantage of the prior art in which a speaker and a media playback module are installed separately (e.g. cable cleanup, space restrictions, etc.). In particular, as a multi-channel speaker including a woofer speaker is structured in the form of a twin tower in which a block equipped with a media playback module and a block equipped with a woofer speaker are separated from each other, the present invention can resolve the problem of the durability of the media playback module caused by the vibrations of the woofer speaker while producing an interior effect.

Description

Hybrid media player with speaker combination

The present invention generally relates to a structure in which a speaker is coupled to a media player (eg, set-top box, audio player, video player).

More specifically, the present invention provides a speaker block and a media playback module equipped with a multi-channel speaker to overcome the disadvantages of the prior art (eg, track interior work, space limitation, etc.) for separately installing the speaker and the media playback module. The onboard playback module block is integrated through the docking interface.

In particular, in the case of a multi-channel speaker including a woofer speaker, the block in which the media playback module is mounted and the block in which the woofer speaker is mounted are separated and configured in a twin tower form to produce an interior effect and media generated by vibration of the woofer speaker. The durability problem of the regeneration module was also solved.

In general, the sound has an audible frequency for each frequency band divided into low, mid, and high frequencies.As such, a plurality of speakers made of sound optimized for the corresponding band are divided into multiple channels (for example, 6.1 channels). Done.

For example, a speaker having 6.1 channels includes six full range speakers and one woofer speaker that outputs only vibration.

Here, in the related art, in order to implement a so-called 'home theater' when watching a broadcast or watching a movie through a TV, a multi-channel speaker may be separately installed in place of a low quality speaker provided in the TV itself.

However, such a conventional multi-channel speaker installation is not only very cumbersome, but also has a disadvantage in terms of spatial constraints and aesthetic reasons because it is a pattern in which a TV, a set-top box, and a plurality of speakers are separately arranged.

To overcome this, a product called the so-called sound bar has been introduced, in which a multi-channel speaker is mounted in a long housing. However, even in this case, the set-top box, sound bar, and woofer speaker are separately installed, which solves some of the disadvantages and still has disadvantages.

The prior art found by the inventors in connection with the present invention is as follows.
