Embodiment 1）

[0070] See figure 1 , diagram 2-1 , Figure 2-2 , Figure 2-3 with image 3 , The plastic high-fidelity combination speaker of this embodiment includes a box body 100, an inverter tube 5, a speaker base 6, a woofer 7, a midrange speaker 8, a tweeter 9, a silicone foam strip 10 and a partition 11. There is one woofer 7, two midrange speakers 8, and one tweeter 9.

[0071] See Figure 2-2 , Figure 2-3 with image 3 , the box 100 is a cuboid box. The box body 100 is provided with several reinforcing ribs. The box body 100 is formed by fixing the front cover 12 on the rear cover 1 from the front through fasteners (not shown in the figure). Both the rear cover 1 and the front cover 12 are injection-molded integral parts. The materials of the rear cover 1 and the front cover 12 are all reinforced polypropylene materials, preferably reinforced polypropylene with 20% calcium carbonate added. The reinforced polypropylene is manufactured by Qingdao Zhongxin Huamei Plastic C...

Abstract

The invention relates to a plastic high-fidelity combinedloudspeaker box. The combined loudspeaker box comprises a box body, a subwoofer and a partition plate. The box body is provided with a plurality of reinforcing ribs and the box body is a cuboid box body. It also includes an invertertube, a mid-range speaker and a tweeter. The box body is formed by fixing a front cover on a rear cover from the front. The front cover and the rear cover are all injection molded as one piece. The partition plate is arranged in the middle part of the box body to form an upper sound cavity and a lower sound cavity, so that the combined sound box is divided into an upper part of the sound box and a lower part of the sound box by the partition plate. The tweeter and the mid-range loudspeaker are located in that upper cavity. A subwoofer and invert tube are located in that lower cavity. The combined loudspeaker box of the invention is small in volume and is made of plastic instead of wood. The upper soundcavity and the lower sound cavity are separated by a partition plate and are not communicated with each other, and the lower sound cavity is an independent bass cavity, so as to realize the independence of the bass audio and ensure the sound quality of the loudspeaker.

Description

technical field [0001] The invention relates to a sound box, in particular to a high-fidelity combined sound box with a plastic box body. Background technique [0002] At present, the cabinets of most speakers are made of wood. On the one hand, it accelerates the destruction of forest resources. On the other hand, the process of wood processing is long, and there is deformation of wood. The life of wooden cabinets is not long. At the same time, most of the current combination speakers arrange the treble, midrange, woofer and circuit board in the same box. Although this arrangement can facilitate assembly and processing, the treble, midrange and woofer are in the same box In a box, the audio of each speaker interferes with each other, especially the sound effect of the bass part is greatly affected. In order to achieve a better sound effect, the speaker usually adopts a split structure, which generally includes a power amplifier and at least two speaker cabinets, but the spl...
