Description

An integrated structure of flat panel TV sound box

technical field

The invention relates to the field of an integrated sound box for a TV or a display, and more specifically relates to an integrated structure of a sound box for a flat-panel TV with low cost and simple structure.

Background technique

The current flat-panel TVs or monitors, such as LCD TVs or plasma TVs, have gradually replaced traditional CRT TVs or projection TVs, and the thickness of existing flat-panel TVs is getting thinner and thinner. Now the thickness of the thinnest TVs on the market can reach 1~2cm. Although the flattening of TVs greatly reduces the installation space and makes the appearance more beautiful, for speakers that need a certain resonance space, the sound effect of TVs is greatly limited. In order to solve the contradictory problem between the volume of the sound box and the thickness of the flat-panel TV, most TVs in the prior art use patch-type speakers, but the sound quality is greatly reduced. In order to ensure sound quality, external speakers have gradually become a trend. The external speaker not only increases the cost, but also has many connectors, and its installation is very cumbersome. The weight of the speaker is equivalent to that of the TV. If the installation is not correct, the center will easily become unstable, and the TV will easily fall over after being placed.

The weight reduction brought about by the flattening of the TV has greatly improved the stability of the suspension installation method, but for the placement structure, the stability has decreased due to the use of external speakers. Most of the existing external speakers that match the flat-panel TV are horizontal-strip speakers that are suspended below the flat-panel TV. The length of the horizontal-strip speaker matches the width of the flat-panel TV. However, the existing placement structure brackets are all connected to the back of the TV, which is already an eccentric structure. In addition, the thicker speakers are suspended under the TV, which makes the structure of the eccentric support more prominent, and the weight of the speakers and the TV Not even. Therefore, the front-to-back ratio of the support needs to be adjusted. Generally, the length of the front support is slightly longer than the length of the rear support, otherwise it is easy to topple under the action of external force.

From the visual effect after installation, as shown in Figure 1, the existing external speaker 102 is generally connected with the flat panel TV 101 through the connector 103 on the back, and the back of the external speaker 102 is flush with the flat panel TV, but due to the thickness Larger, the front appears to protrude, not only the appearance is not beautiful, but also causes the center to be forward. Therefore, the length of the front side of the support 104 of the flat-panel TV 101 is greater than the length of the back side, and a wider space is required for a natural placement position. The TV is generally placed in a more conspicuous position in the living room, and the uncoordinated appearance and structure will have a great impact on the decoration style of the entire living room.

Contents of the invention

The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art, and design an integrated structure of flat panel TV sound box with simple structure, convenient installation, high stability after installation and low cost manufacturing.

The present invention realizes the above-mentioned object of the invention through the following technical solutions.

The present invention further improves the installation structure of the prior art, and designs an integrated structure of a flat panel TV sound box, including a flat panel TV, a long strip sound box and a bracket matching the width of the flat TV, and the improved structure lies in the The horizontal bar speaker is provided with a through hole that runs through the speaker up and down, the bracket passes through the through hole, the upper end of the bracket is connected with the flat TV to support the flat TV, and the lower end extends back and forth to support the entire structure, that is, the width or length of the lower end is greater than that of the through hole. hole. The present invention saves connecting components between the flat panel TV and the horizontal sound box through the installation method in which the bracket passes through the middle of the horizontal sound box, further simplifies the installation structure, thereby reducing the cost and the difficulty of assembly. On the other hand, passing through the middle of the horizontal sound box, the centers of gravity of the horizontal sound box and the flat-panel TV basically overlap after installation, which improves the stability of the structure. In addition to the center of gravity, the bracket passes through the horizontal sound box to form an integrated structure. The horizontal sound box is heavy, and the center of gravity of the entire support structure is relatively low, and the stability is improved, so that it can support a larger flat-panel TV. In terms of appearance, the protruding part of the horizontal bar speaker in front of the flat-panel TV is reduced, and the length of the front side of the base of the bracket can be further shortened, which makes the entire installation structure flatter both in terms of actual size and visual effect on the side. It is more convenient to place and the visual effect is more beautiful.

Due to the improvement of structural stability, the bracket structure can be further simplified, so that the product has space to further reduce the cost. The invention further simplifies the bracket: including the support seat at the upper end, the connecting part and the bottom that run through the horizontal sound box in the middle end base. Simplified installation structure, the weight of the horizontal bar is directly loaded on the base without other connecting parts. The flat-panel TV is connected to the support base, the connection method can be plug-in or the screw holes on the back of the flat-panel TV are connected by screws. The length of the connecting part basically matches the height of the horizontal sound box, and the weight of the flat-panel TV is transferred to the The base is distributed to the horizontal sound box, so the weight of the entire structure is directly loaded on the supporting part without any intermediate indirect transmission process, which is different from the transmission mode of the prior art sound box-TV-base, and the stability of the installation structure is further improved . Although the connecting part is a heavy main component, because it passes through the middle of the horizontal sound box, its thickness can be made very thin, and the insufficient thickness can be made up by distributing stress to the horizontal sound box body, thus The support for the flat-panel TV can be realized through a simple flat-panel.

It can be seen from the above analysis that the present invention not only simplifies the structure of the bracket, but also reasonably distributes the internal stress distribution of the installation structure, ensuring that the bracket has the same supporting force as the original complex structure. On the premise of solving the load-bearing problem, the inventor found that since the base part is mainly to prevent the entire structure from overturning during use, and the extension part of the base is mainly subjected to torque, the base can be simplified and grown according to the force characteristics. In order to ensure the transmission of gravity without causing more torque due to the imbalance of the center of gravity, the strip plate structure is perpendicular to the connecting part. This not only can further simplify the structure, but also ensures the stability of the structure. After the above-mentioned improvement, the protruding length of the front side of the base does not need to protrude longer to balance the center of gravity as in the prior art, and the length of the rear side can also be shortened accordingly. Therefore, compared with the prior art, the length of the entire base as a whole In this way, the horizontal space for placing the TV set can be further shortened, making the placement more flexible.

When the user hangs the flat-panel TV on the wall, the base is not needed as a support. Therefore, in order to meet the actual needs of different users, the base and the connecting part of the present invention are detachably connected, and the connecting part and the connecting end of the base wider than the through hole. In this way, when the hanging installation method is adopted, the base can be removed, and the horizontal bar speaker can be directly hung on the connecting part. The force-bearing structure is similar to the prior art, but the installation is simpler. The remaining part of the support can be connected to the flat-screen TV after passing through the horizontal sound box, without any screw connection.

Since the through holes used to pass through are provided on the horizontal bar sound box, in order to improve the sealing performance of the sound box and further ensure the sound quality of the sound box, a sealing structure is provided between the bracket and the through hole in the present invention. The sealed structure has the function of preventing dust and air leakage, so that the speakers in the horizontal bar box can keep resonating in a closed space and have better sound effects.

The sealing structure can have various forms. For the convenience of installation, the preferred solution of the present invention includes upper and lower sealing rings sleeved on the bracket and embedded between the bracket and the through hole. In order to improve the sealing performance, an I-shaped sealing rubber ring can also be preferred. The middle part runs through the horizontal bar sound box, and the upper and lower protruding parts cover the through hole. The sealing rubber ring is provided with a vertically penetrating channel for passing through the bracket.

A plurality of loudspeakers are arranged in a general horizontal bar sound box, and since a through hole is provided on the casing, a partition may also be provided between the loudspeaker and the through hole, so that the above-mentioned loudspeaker has an independent and airtight resonance space. The direction of the woofer is downward, and the horizontal bar speaker is supported by the base to keep a certain distance from the support surface. The downward direction of the woofer can form a natural sound reflection surface, which has the effect of further improving the subwoofer effect.

In the present invention, different numbers of bracket units with the same structure as the above-mentioned structure can be provided, and an appropriate number and an appropriate installation position can be selected according to the size of the flat-panel TV or flat-panel display. For example, for a flat-screen TV with a small size, the bracket generally includes a bracket unit, which is arranged in the middle of the flat-screen TV and the horizontal sound box. For a flat-screen TV with a larger screen, the bracket includes two bracket units, which are symmetrically arranged under the flat-panel TV and the horizontal sound box. Generally, there are rarely more than two bracket units, and a center bracket can be added in a few special cases. unit as an auxiliary.
