The present invention relates to a bass speaker device of a television receiver.

Currently, a bass speaker is attached to the top of a television receiver. Since the speaker case is assembled into three or four parts, the assembly work is difficult and the parts cost a lot.

It is an object of the present invention to provide a bass speaker device of a television receiver with a sound effect is improved by configuring the bass speaker device into an upper case and a lower case to eliminate the above-mentioned disadvantages, and split the rear speaker into two. .

The present invention will be described below with reference to the accompanying drawings.

The bass speaker device of the present invention is composed of an upper case 1 shown in FIGS. 1 and 2 and a lower case 2 shown in FIG. 3 and FIG.

Referring to FIGS. 1 and 2, the upper case 1 has a diverging hole 10 through which a speaker sound is emitted at the right front, and the lower case 2 is coupled to the upper plate 3 of the upper case 1. Nut portions 11, 12, 13, and 14 which are joined to the protrusions up and down are formed. Meanwhile, an extension part 15 is formed at the left edge of the upper plate 3, and fastening protrusions 16 and 17 coupled to the rear corner coupling protrusion of the lower case 2 protrude from the lower end of the extension part 15. have.

Referring to FIGS. 3 and 4, the lower case 2 is formed with a speaker mount 20 to which a woofer speaker is attached at the center, and partition walls 21 and 22 from the speaker mount 20 to the right front side. This extension causes the speaker sound to be separated into the front sound and the rear sound by the partition walls 21 and 22, and two rear sound holes 23 and 24 are formed.

The bottom plate 4 of the lower case 2 is coupled to the nut (11), (12), (13) and (14) of the upper case (1) engaging projections (25), (26), (27) and (28) are formed, and fixing rods (29) and (30) are inserted into and fixed to the television receiver on the outer wall of the bottom plate (4). In addition, at the left edge of the bottom plate 4, coupling protrusions 31 and 32 to which the fastening protrusions 16 and 17 of the upper case 1 are coupled are formed.

5 shows a state in which the upper case 1 of the present invention is coupled to the lower case 2, and the nut parts 11, 12, 13, and 14 of the upper case 1 are The coupling protrusions 25, 26, 27, and 28 of the lower case 2 are coupled to each other and fastened by bolts, and the fastening protrusions 16 and 17 of the upper case 1 are connected to the lower case ( It is coupled with the engaging projections 31 and 32 of 2).

The bass speaker device of the television receiver of the present invention configured as described above is composed of the upper case (1) and the lower case (2) for easy assembly, and two rear mouths (23) and (24) are formed and the sound effect is improved Has an advantage.

Claims (1)
