Description

a horizontal speaker

technical field

The utility model relates to the field of integrated sound boxes for televisions or monitors, in particular to a horizontal bar sound box 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 utility model is to overcome the deficiencies of the prior art, and design a horizontal bar sound box with simple structure, convenient installation, high stability after installation and low cost manufacturing.

The utility model saves the connecting components between the flat panel TV and the horizontal sound box through the installation mode 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 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.

In order to facilitate installation, the preferred solution of the utility model is to include 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.

The structure of the utility model is very simple, and the manufacturing process is further simplified. The through hole is formed by extending the top surface of the sound box body to the bottom surface of the sound box body, so that a channel isolated from the inside of the sound box body is naturally formed, and there is no need to add a sealing structure. Or the main body of the speaker is integrally stretched and formed by an aluminum extrusion process. This process can mass-produce the main body of the speaker at high speed and low cost. Compared with the existing process of reassembling after injection molding, the production efficiency is greatly improved. The through hole is The holes corresponding to the top and bottom of the speaker body respectively can be further sealed by the sealing structure.

In order to improve the sound effect of the flat panel TV, the speaker further includes a subwoofer. 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. Wherein the woofer faces the bottom of the main body of the speaker, the horizontal bar speaker is supported by the base to keep a certain distance from the support surface, and the woofer facing downward can form a natural sound reflection surface, which can further improve the subwoofer effect.

Because the weight of the woofer is heavy and the vibration is strong, it is used to directly support the flat-panel TV or monitor, which will have a certain impact on the viewing quality. In order to improve the viewing quality, the weight of the entire structure should be balanced. The utility model comprises at least one pair of subwoofer speakers, and the two subwoofer speakers are separately arranged at both ends of the sound box main body, and the speakers of other channels are arranged between the pair of subwoofer speakers.

The preferred structure of the utility model is that the horizontal bar sound box is provided with two through holes which run through the main body of the sound box up and down and are used to pass through the bracket. between holes. This structure fully considers the weight of the flat-panel TV to be supported, the uniform distribution of internal stress when the gravity is transmitted to the supporting structure, and the impact on the superstructure caused by the improvement of the sound quality. Considering the above factors, two through holes are set separately on the main body of the speaker, and two brackets are pierced. The length of the connecting part of the bracket is roughly the same as the height of the horizontal bar speaker. After installation, the upper and lower surfaces of the horizontal bar speaker are close to the support. The seat and base are more conducive to the transmission and distribution of force, and can directly distribute the weight of the flat-panel TV installed on the support seat evenly to the horizontal sound box, which is conducive to improving the stability of the structure. In addition, it is also possible to further reduce the influence of the vibration of the subwoofer on the flat-screen TV.

The utility model can be provided with different numbers of support units with the same structure as the above-mentioned structure, and selects a suitable number and a suitable installation position 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.
