Embodiment 1

[0047] Such as Figure 1A , Figure 1B As shown, the end face of the large box body 5 of the present embodiment is a rectangle (quadrilateral), and the end face of the small box body 6 is a regular hexagon. Small casing 6 is nested in large casing 5, and the volume of large casing 5 is greater than the volume of small casing 6, and the end faces of front and back ends of big casing 5 are coplanar with the end faces of small casing 6 front and rear ends respectively, can like this Reduce the thickness of subwoofer 2.

[0048] Have the second sound outlet 10 on the front end face of big box 5 and small box 6 coplanar, be installed in the small box 6 and communicate with ambient atmosphere through this second sound outlet 10, in small box 6 and the second sound guide tube 11 that conducts the sound wave airflow between the ambient atmosphere. The first sound outlet 8 is arranged on the large box body 5, and the first sound wave airflow is connected with the ambient atmosphere t...

Embodiment 2

[0051] Such as Figure 2A , Figure 2B As shown, the difference between this embodiment and the first embodiment is that the two sides of the large box body 5 are designed as curved surfaces, which can be applied to different installation conditions, and the others are the same as the first embodiment.

Embodiment 3

[0053] Such as Figure 3A , Figure 3B As shown, the difference between this embodiment and Embodiment 1 is that the end faces of the large box body 5 and the small box body 6 are all regular pentagons, and among the five sides of the large box body 5, one side at the upper left of the small box body 6 There is a first sound outlet 8 on the side where it is located, and the first sound guide tube 9 is located in the large box 5, and one end is installed at the position where the first sound outlet 8 is opened. Present embodiment is all equipped with a loudspeaker unit 7 on five side surfaces of small cabinet 6, and all loudspeaker units 7 are identical woofers, and loudspeaker unit can be circular also can be oval, and the size of loudspeaker unit 7 It is 20~200mm, and the circular woofer used in this embodiment has a size of 52mm in diameter. The installation directions of the five speaker units 7 are the same or different. This embodiment adopts the same installation direc...

Abstract

The invention relates a bass sound box, and specifically relates to a dual-box subwoofer and a television set internally provided with the same. A small box of the subwoofer is disposed inside a large box of the subwoofer. The small box and the large box are cylinder-shaped, and the end surfaces of the small box and the large box are polygon-shaped. At least one end surface of the small box is coplanar with at least one end surface of the large box, and the coplanar end surface of the large box and the small box is provided with a second sound port. A second sound guiding tube is disposed inside the small box, wherein the second sound guiding tube is communicated with the ambient atmosphere through the second sound port, and sound wave airflow is transmitted between the small box and the ambient atmosphere through the second sound guiding tube. The large box is provided with a first sound port, and a first sound guiding tube is disposed inside the large box, wherein the first sound guiding tube is communicated with the ambient atmosphere through the first sound port, and the sound wave airflow is transmitted between the large box and the ambient atmosphere through the first sound guiding tube. The first sound port is arranged in the end surface at the other end of the large box, or in the side surface provided with any edge of the polygon, or is coplanar with the second sound port. Loudspeaker units are mounted on the small box. The dual-box subwoofer is advantaged by good bass effects, small size and non-distortion.

Description

technical field [0001] The invention relates to a subwoofer sound box, in particular to a double-box subwoofer and a television set with the double-box subwoofer built in. Background technique [0002] As we all know, TV technology, especially flat-panel TV technology, is developing rapidly, and people have higher and higher requirements for TV; and the quality of TV is two pursuits, one is good picture, and the other is good sound. The current flat-panel TV is getting thinner and thinner, and the picture is getting better and better, but the sound is getting worse and worse as it gets thinner. The effect of the bass pronunciation is poor. In the "Speaker and Sound Box Design Manual" published by Fujian Science and Technology Press in July 2008, the closed sound box (60-67 pages), the open-type sound box (67-77 pages), the passive radiation sound box (77 pages) are disclosed. ~78 pages). When these open technologies are used in flat-panel TVs, because flat-panel TVs are t...
