Description

  The present invention relates to a speaker box having a function as a television stand.

The television has a display device for displaying an image, and a speaker for generating sound. Meanwhile, conventional general television speakers are arranged on both sides of the display device or on the lower side. That is, it has a structure in which the speaker is incorporated in the housing constituting the display device.
In order to prevent the vibration of the speaker from being transmitted to the housing when the speaker is fixed, the speaker is generally attached to the housing via a vibration isolating material such as an insulator or a vibration absorbing material.

By the way, a speaker may be provided not on the housing of the display device but on a pedestal portion of a stand that supports the display device.
For example, “Stand and display device” according to Japanese Patent Application Laid-Open No. 2008-154084 prevents the display device from vibrating due to the vibration of a speaker provided in the television.
The television includes a display device and a stand, and the display device and the stand are configured to be easily detachable. The stand includes a stand base that hits the pedestal and a cylindrical column, and the column includes first and second speakers.

A “stand with a speaker” according to Japanese Patent Application Laid-Open No. 2011-239371 is a TV mount that reproduces a TV or the like as more powerful voice / sound and improves strength.
That is, a pedestal having a pedestal on which an article can be placed, and a plurality of speakers are incorporated in the pedestal, and has at least two strut plates in a vertical direction partitioning the internal space of the pedestal, At least a part of the partitioned space constitutes a duct having an opening to the outside of the pedestal, and at least one speaker (preferably a subwoofer) is incorporated inside the pedestal and is directed to the duct.

In addition to these, a “thin display device” according to Japanese Patent Laid-Open No. 2009-267577, a “display housing and a television receiver” according to Japanese Patent Laid-Open No. 2014-195165, and the like are known.
“Stand and display device” according to Japanese Patent Application Laid-Open No. 2008-154084 “Mount with speaker” according to Japanese Patent Application Laid-Open No. 2011-239371 “Thin Display Device” according to Japanese Patent Application Laid-Open No. 2009-267577 “Display device casing and television receiver” according to Japanese Patent Application Laid-Open No. 2014-195165

As described above, various televisions in which a speaker is incorporated in a stand are known. However, there is no known stand that can efficiently suppress vibration based on heavy bass emitted from speakers, particularly woofer speakers.
The present invention is configured by incorporating a speaker into a stand, and this point is in common with a conventional stand. The problem to be solved by the present invention is to provide a speaker box having a TV stand function configured to suppress vibration based on heavy bass of a woofer speaker.

  A television set according to the present invention includes a display device and a stand, and the display device is attached to the stand and stands vertically. Here, the stand is configured not only to support the display device but also as a speaker box that accommodates the speaker, and a woofer speaker capable of generating heavy bass is attached downward (toward the floor) at the center. On both sides, speakers that generate medium and high sounds are arranged facing the front.

A plurality of poles stand up at the center of the bottom plate of the speaker box, and woofer speakers are arranged at the upper ends of the poles. Is fixed.
Here, the shape of the woofer fixing bracket is not limited, but generally, a hole is passed through the bottom plate, and a pressing portion is erected on the outer side of the bottom plate.

In addition, a plurality of pillars stand in addition to the poles at the center of the bottom plate of the speaker box, and these pillars are covered with pressing parts provided on the woofer fixing bracket. An upper cover is attached to the bottom plate to which various speakers are attached.
By the way, a display device fixture is attached to the display device, and this display device fixture is screwed on a support column provided upright on the bottom plate. In this case, the woofer fixing bracket is screwed together with the support column, and simultaneously the load of the display device acts on the woofer fixing bracket via the pressing portion.

The speaker box of the present invention accommodates a speaker therein, and a display device is placed at the same time. Therefore, the display device fixture attached to the lower end of the central portion of the display device is placed on the central portion of the speaker box in which the woofer speakers are arranged, and the woofer speakers can be fixed. That is, the weight of the display device is designed to hold the woofer fixing bracket to which the woofer speaker is attached.
Therefore, it is possible to suppress vibration based on low-duty sound emitted from the woofer speaker, and to provide high sound quality. Here, the structure for attaching the woofer fixing bracket and the woofer speaker is not limited.
