Improved shell speaker system for television

The present invention relates to a shell-type speaker device that is installed when the installation space due to the CRT installed inside the TV front mask is narrow. More specifically, the grille is integrally formed on the front and side of the front mask where the CRT is installed. The front and rear of the upper and lower sides of the high information bulge respectively, the fixing piece of the sounding plate is screwed, the sounding plate is formed in a b-shape so that the grill side portion of the front mask is opened and wrapped, the rear center of the speaker mounting The groove is integrally formed so that the speaker is coupled, and upper and lower cover plates are integrally formed.

Accordingly, when installing the shell-type speaker of the TV, by installing a ring plate without installing a separate speaker ring conduit in the front mask, manufacturing cost is reduced, and various sounds are emitted through grills formed on the front and side surfaces of the front mask. The present invention relates to a shell-type speaker device of a television, which improves sound quality and eliminates the need for a separate vibration absorber such as a black woven fabric, thereby allowing a speaker installation space to be improved, thereby improving the assembly productivity of the television.

In general, in a television, when the speaker cannot be directly installed because there is little space between the CRT and the side walls of the left and right front masks, a shell-type speaker using a ringing conduit extending from the rear of the front mask and extending rearward is installed.

In the conventional shell type speaker of the related art, as shown in Figs. 1 and 2, the front mask is provided on the fixed ribs 115 provided on the front and upper and lower sides of the ring conduit 111 for the shell speaker 110. The high information 102 installed on the inner side of the inner side of the 101 is screwed, the speaker grill 103 is integrally formed on both front sides of the front mask 101, through the speaker grill 103 Long grooves 112 and 112 ′ are respectively formed in the front and rear centers so as to emit sound, and the speaker 114 is screwed into the coupling grooves 113 formed at the upper and lower sides of the rear conduit 111, respectively. It is made of a structure in which the black woven fabric 104, which is a sound absorbing material to absorb the vibration between the outer surface of the ring conduit 111 and the inner surface of the front mask 101 is coupled.

In such a conventional TV shell type speaker, as shown in Figs. 1 and 2, when the space due to the front mask 101 and the cathode ray tube (not shown) inside thereof is narrow, the rear surface is enlarged. After installing the ringing conduit 111, the speaker 114 is mounted to the rear of the ringing conduit 111 to process the sound of the television 100, wherein the front of the ringing conduit 111 is a front mask ( 101) narrowly formed so as to be installed in the free space between the CRT.

However, in the conventional shell-type speaker for television as described above, as shown in FIGS. 1 and 2, the vibration generated in the ring conduit 111 during speaker vibration is reduced as the sound absorbing material 104 such as black woven fabric. To some extent, the front mask 101 is affected, and when the front mask 101 vibrates, vibration is transmitted to the CRT installed in the front mask 101 so that the image of the CRT becomes unstable (screen distortion). , There was a disadvantage that a separate space for attaching the black woven fabric 104 is required.

In addition, there is a need for additional work for attaching the sound absorbing material 104, and the manufacturing cost of the hermetic ringing conduit 111 is increased to increase the manufacturing cost of the shell type speaker 110.

The present invention has been devised to improve the various problems as described above, the purpose of which is, when installing the shell-type speaker of the TV, by installing an open ring plate on one side without installing a separate speaker ring conduit in the front mask In addition, the manufacturing cost is reduced, and grills are formed on the front and side surfaces of the front mask, so that the sound quality is improved by various sound emission, and the speaker installation space is more spacious. SUMMARY OF THE INVENTION An object of the present invention is to provide an improved shell-type speaker device for televisions, in which the portion is narrowed to make the appearance of the television more beautiful.
