DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION This invention relates <br/> can Angeles speaker system using the display apparatus using such as a cathode ray tube for use in an output display device in a television receiver or computer equipment .

[0002]

2. Description of the Related Art A display device for outputting an image or the like in a television receiver or a computer device using a cathode ray tube or a liquid crystal (hereinafter, these are collectively referred to as "C
RT device ". )), All of which use speakers with built-in speakers . Among them, recently, CRT devices for computers have spread to the world of audio-vidual, which includes not only display of images but also sound and music. I have.

[0003]

However, the speakers incorporated in the conventional CRT device for a computer are all small in size in relation to the CRT device, and the speakers used in audio equipment are high in performance. remarkable difference is the is currently found for the said, when adding the speaker on the CRT device, placing a speaker box incorporating a small speaker on the side of the CRT device or, CR
The T device is processed and the speaker is retrofitted with screws or the like.

[0004] When a speaker is added to such a CRT device, a mere arrangement of the speaker box requires a place where the speaker box is placed, but it is not appropriate in a limited space. In addition, since the additional speaker box is usually located on the right and / or left of the CRT device and smaller than the CRT device, the sound of the speaker is emitted below the ears for the operator facing the CRT device, so that the sound quality is reduced. Is not good, and a stereo feeling cannot be obtained. Also, the method of machining the mounting portion on a CRT device is extremely difficult and expensive, and is virtually impossible unless a skilled technician.

In view of the above situation, the present invention makes it possible to add a desired speaker to a CRT device by extremely simple and easy means, and to easily increase the directivity of the added speaker.
It is an object to provide a speaker system that can be changed .

[0006]

It is assumed that.

In the present invention, a display device equipped with a pair of left and right speaker systems means a display device (CRT device) for outputting an image or the like in a television receiver or a computer device using a cathode ray tube or liquid crystal . Such a CRT device usually has a rectangular or square cubic shape in front, and the speaker system is arranged on the left and right of the cubic CRT device.

In each of the speaker units, a speaker box is mounted on a mounting member to a display device so that the directivity of the speaker is variable. Specifically, a vertical leg of a mounting member having an L-shaped cross section is used. In addition, a speaker box is attached so that the directivity of the speaker is variable.

The mounting members constituting this speaker unit are mounted on upper right and left corners of the front of the CRT device, respectively, and are basically made of metal or synthetic resin and have an L-shaped cross section. Oh Ru, but mounting
In order to minimize damage to the CRT device,
The speaker box is preferably made of resin.
The vertical leg which is in contact with the side surface portion of the CRT device of the shaped member, in the vertical direction is intended to attach preparative rotatably.

The horizontal leg of the L-shaped member is a CRT.
In which the upper surface portion of the apparatus and the abutment, the engaging hole is provided et al, to CRT device abutting for attaching the rope member for Tsunagigi each other speaker units disposed on the upper corner portion of the right and left CRT device A non-slip member is attached to all or part of the site.

A cable member for connecting a pair of speaker units arranged on the left and right sides of the CRT device to each other includes a wire or a wire.
Is a belt-type CRT to be mounted
Preferably, the length can be adjusted freely according to the size of the device.

[0012] In particular, when the cable member is constituted by a belt,
By attaching a hook-and-loop fastener to the back of the left and right tip of the belt, inserting the tip of the belt into the engaging hole formed in the horizontal leg of the mounting member, turning it back, and engaging the hook-and-loop fastener with each other The length can be adjusted freely.

[0013]

In the speaker system according to the present invention, a pair of mounting members each having a speaker box mounted thereon are connected by a cable member. Therefore, the cable member is disposed on the upper surface of the CRT device to be mounted. with the left and right ends of the rope member
By arranging the connected attachment members on the left and right side surfaces of the CRT device, a speaker can be easily added to the CRT device, and the speaker box for holding the speaker box can be provided.
The speaker box by loosening the
It can be moved up and down to change the directivity.
