Embodiment Construction

[0032] see image 3 and Figure 4 , there is a gap δ1 between the speaker 2 in the TV and the speaker base 9 on the casing 1, the gap δ1 should depend on the diaphragm area of ​​the speaker 2 and the frequency value to be increased, generally 0.10-1.50mm, the preferred range is 0.30 -1.0mm.

[0033] In order to make the speaker 2 in a slightly movable state, or "suspension" state, the connection assembly structure between the speaker 2 and the casing 1 has been improved as follows:

[0034] The inner side of the stud 10 of the casing 1 is provided with an inner limit block 8, the outer end surface of the inner limit block 8 protrudes from the end face of the speaker base 9, and the outer limit block is arranged at the outer end of the stud 10. In this embodiment , the outer limit block is the washer 7 fixed by the screw 5 .

[0035] The connecting hole of the basin frame 4 of the loudspeaker 2 is embedded in the shock-absorbing sleeve 6, so that the basin frame 4 and the sh...

Abstract

The invention provides a TV set with a built-in loud speaker and capable of solving the problems of the prior art such as TV vibration and poor low-frequency response of a loud speaker. The invention adopts the following technical proposal: a clearance Delta 1 is arranged between a loud speaker and a loud speaker holder; a speaker frame is movably sleeved on the double-ended bolt of a casing; both the inside and the outside of the double-ended bolt are provided with stop blocks; the speaker frame is arranged between the inside stop block and the outside stop block with a clearance Delta 2 set aside. The TV set overcomes the technical prejudice of acoustic short circuit close connection and adopts a clearance structure form different from close connection, thereby solving the problems such as TV vibration and poor low-frequency response.

Description

technical field [0001] The present invention relates to television sets, in particular to the improvement of the built-in loudspeaker assembly structure in the television set. Background technique [0002] The assembly structure form of the built-in loudspeaker in the existing television is designed based on solving "acoustic short circuit". see figure 1 and figure 2 , the speaker seat on the casing 1 and the bead 3 of the speaker 2 are close to each other to form a closed space V (of course, there are mesh holes on the casing), and the screw 5 passes the speaker 2 tightly through the speaker frame 4. It is fixed on the stud 10 of the casing 1, so that the loudspeaker 2 is connected and fixed with the casing 1. The so-called acoustic short circuit means that the sound waves emitted from the back of the speaker diaphragm go around the front of the diaphragm and interfere with the sound waves emitted in front of the diaphragm, which deteriorates the overall sound frequency...
