Description

Sound bar with adjustable height and thickness

The present disclosure relates to a sound bar used with a display device.

A sound bar is mainly used to enhance the sound quality of a display device, for example, a TV. Therefore, it is common to install and use a sound bar together with a display device.

The sound bar is formed such that a sound transducer and a circuit board driving the sound transducer are included in one body.

In general, when viewed from the front, sound bars are of a first type having a rectangular box shape with a height smaller than a thickness, a second type having a rectangular box shape having a height greater than a thickness, and a third type having a square box shape having the same height and thickness. can be distinguished by type.

The type of sound bar to be used may be determined according to the installation type of the display device.

For example, when the display device is installed on the same floor as the upper surface of the TV bench, that is, when the display device is installed in a stand type, a first type sound bar having a low height is used so as not to cover the screen of the display device.

However, when the display device is installed in a wall-mounted type, a second type sound bar having a small thickness is used so that the sound bar does not protrude too much from the wall when viewed from the side.

In recent years, as TVs have become larger and larger, there are many cases in which TVs are installed in a wall-mounted type. Accordingly, more and more products of the second type suitable for the wall-mounted type of sound bar are also increasing.

In this case, a sound bar having a thickness as thin as possible is required, but since the sound transducer and the circuit board are all installed in one box, it is difficult to make the sound bar thin.

In addition, in the case of purchasing the first type sound bar, if the sound bar is installed in a wall-mounted type, there is a problem in that it does not look good.

On the other hand, when a sound bar of the second type is purchased, there is a problem in that the TV screen or the remote control sensor may be covered when the sound bar is installed on the floor.
