Description

Display device {DISPLAY DEVICE}

The present invention relates to a display device, and more particularly, to a display device capable of improving the sound quality of a speaker without requiring an enclosure by providing a chamber inside the case for shielding soundproofing after the speaker.

A display device such as a television receiver includes a speaker for outputting sound. The speaker includes a diaphragm that generates sound through vibration, and the diaphragm generates sound at the front and rear. However, since the sound after the diaphragm has a phase opposite to that of the diaphragm before the diaphragm, there is a problem that the sound quality is deteriorated due to the destructive interference caused by mixing the diaphragm front sound and the sound after the diaphragm.

On the other hand, it is preferable that a chamber having a constant volume is formed behind the diaphragm. The air in the chamber acts as an air suspension that supports the diaphragm and provides a restoring force, thereby performing a function of smoothly vibrating the diaphragm. However, when the chamber volume is too small as compared with the diaphragm area, the air suspension function is deteriorated. On the other hand, when the chamber volume is too large, the suspension function is also deteriorated due to pressure balance.

Fig. 1 shows a speaker 10 incorporating a conventional chamber. 1, the front face of the diaphragm 11 is exposed through the opening of the speaker case 12 and the rear face of the diaphragm 11 is sealed by the speaker case 12, Is shielded by the speaker case (12) and the front soundproofing of the diaphragm (11). On the other hand, the speaker case 12 seals the rear surface of the diaphragm 11, and the space inside the case 12 on the rear surface of the diaphragm 11 functions as a chamber.

The conventional chamber-embedded speaker 10 has the following problems.

 First, since the speaker case 12 includes a chamber below the diaphragm, there is a problem that the speaker height H1 increases. The increase in the speaker height (H1) is a factor that makes it difficult to reduce the thickness of the flat panel display and the slim bezel according to recent design trends.

Secondly, it is difficult to secure an appropriate chamber volume in comparison with the area of the diaphragm for the reason described above, so that the air suspension effect by the air in the chamber is deteriorated and the sound quality is deteriorated.

Third, the conventional speaker 10 is connected to the main board of the display device through an extension line extending from the voice coil and the pad 13 to receive a voice signal. The pad 13 is usually connected to the output terminal of the main board through a conductive member such as solder. Therefore, the internal structure of the TV becomes complicated due to the speaker wiring, and it is difficult to mount or replace the speaker 10. For example, when replacing the speaker 10 with the failure of the speaker 10, a skilled artisan disassembles the TV case and removes the solder of the pad 13 to separate the failed speaker 10 from the main board, ) Is mounted on the main board through soldering, and a complicated and specialized procedure for assembling the TV case is performed, thereby increasing time and cost for the AS.

2 and 3 show a speaker 20 in which a chamber is formed on the outside. First, the speaker 20 includes a frame 22 which does not include the case 12 and at least one side is open, unlike the speaker 10 of FIG. Such a structure of the speaker 20 is disclosed in Korean Patent Registration No. 1179893 "Speaker ". On the other hand, when the bottom case, not the frame, is used, an air hole is formed in the bottom of the case 12 so that air can flow into and out of the chamber inside the enclosure 30. Such a speaker structure is disclosed in Korean Patent Registration No. 1174833, "Speaker Module Incorporating a Rectangular Damper ".

The enclosure 30 includes a chamber therein and includes a speaker seating groove that is open to allow the speaker 20 to engage. The enclosure 30 is formed to have an area equal to or larger than the area of the diaphragm 10 so as to secure a sufficient space therein. The diaphragm 21 is attached to the outside of the enclosure 30 while the enclosure 30 and the speaker 20 are coupled and the soundproofing of the diaphragm 21 is isolated from the chamber inside the enclosure 30, It is isolated from sound insulation. Next, the chamber of the enclosure 30 is formed in a volume suitable for providing an air suspension to the diaphragm 21, thereby providing an effect of improving the sound quality of the speaker 20.

However, the speaker 10 coupled with the enclosure 30 has the following problems.

First, the manufacturing cost of the speaker unit is increased due to the enclosure 30 using the large panel. In currently commercially available display component speakers, the enclosed speaker of FIG. 3 trades at about five times more than the internal chamber speaker of FIG. As a result, the enclosure 30 increases the manufacturing cost of the display device as well as the manufacturing cost of the speaker.

Second, Fig. 4 shows a cross section of the display with the enclosure 30 mounted on the display case 40. Fig. The enclosure 30 is mounted inside the display panel 42 and the display case 41. The thickness w1 of the enclosure 30 is a factor that increases the thickness W2 of the display device do. That is, the display thickness W2 of the enclosure 30 is increased by the thickness of the upper plate and the lower plate. As a result, there is a problem that it becomes difficult to make the display device slim down, which is a recent tendency.

3, the speaker 20 of FIGS. 2 and 3 is connected to the main board of the display device through an extension line extending from the voice coil and a pad 23 to receive a voice signal to be. Therefore, there is a problem that it is difficult to mount and replace the speaker 20. Furthermore, since the operation of separating the speaker 20 from the enclosure 30 is further required when the speaker 20 is replaced or the speaker 20 is replaced by the enclosure 30, There is a problem of further increase.
