Embodiment 1

[0029] Such as figure 1 , figure 2 Shown, the casing 1 of present embodiment is cuboid, symmetrical with the center line of casing 1 width direction; Casing body 1 can be manufactured with mold-opening injection molding method, also can use other materials such as metal material (as aluminum, iron) , timber or plastic board etc. manufacturing; The casing 1 of present embodiment adopts mold-opening injection molding method to manufacture, and casing 1 is carried out industrial design earlier, carries out mold-opening after appearance design is good, then manufactures with injection molding machine.

[0030] The first speaker group 3 of this embodiment is installed on the right end box wall 7 at one end of the box body 1, and the diaphragm of the first speaker group 3 is arranged towards the outside of the box body 1; the second speaker group 4 is installed on the other side of the box body 1 On the left end box wall 8 at one end, the diaphragm of the second speaker group 4 is...

Embodiment 2

[0035] Such as image 3 , Figure 4As shown, the difference between this embodiment and Embodiment 1 is that the box body 1 is divided into two identical and independent cavities, namely the left box body 12 and the right box body 13, and the middle is connected by a partition box wall 11 and completes the left box body. , the isolation of the right box body 12,13; meanwhile, the first bass radiator 5 and the second bass radiator 6 are separated into two identical bass radiators respectively, that is, the first bass radiator 5 is separated by the partition box wall 11 The left first bass radiator 14, the right first bass radiator 15, the second bass radiator 6 is separated by the partition box wall 11 into the left second bass radiator 16, the right second bass radiator 17. The partition box wall 11 is located in the middle of the box body 1 , and the left box body 12 and the right box body 13 are symmetrical to the partition box wall 11 . The first loudspeaker group 3 is in...

Embodiment 3

[0037] Such as Figure 5 , Figure 6 As shown, the difference between this embodiment and Embodiment 1 is that the first bass radiator 5 is installed on the rear box wall of the box body 1, the second bass radiator 6 is installed on the front box wall of the box body 1, and the rear box The part where the first bass radiator 5 is installed on the wall is recessed to the inside of the box body 1 to form the second inner box wall 18, and the left and right ends of the second inner box wall 18 and the unsag part of the rear box wall are respectively separated by a second wall. The inner box wall 19; the part where the second bass radiator 6 is installed on the front box wall is sunken to the inside of the box body 1 to form the first inner box wall 9, and the left and right ends of the first inner box wall 9 are not sunken with the front box wall Between the parts are the first inner box walls 10 respectively. In this embodiment, the first inner box wall 9 , the second inner bo...

Abstract

The invention relates to sound boxes of sound equipment, and specifically relates to a two-end-type double-diaphragm resonance sound box. Two loudspeaker groups are respectively and symmetrically installed on end surfaces of left and right two ends of a box body. Two bass radiators are respectively installed on box walls of the box body between the two loudspeaker groups, and the two bass radiators are opposite to each other. The part, provided with any one bass radiator, of the box wall is concave towards the inner part of the box body so as to form an inner box wall, or the parts, provided with the two bass radiators, of the box wall are respectively concave towards the inner part of the box body so as to form inner box walls, and the parts between the inner box walls and the non-concave box walls are inner side box walls. Medium-high frequency sound waves of the loudspeakers are directly radiated to space from two ends of the box body, low frequency sound air flows drive the two passive bass radiators to vibrate symmetrically, the bass diaphragm area in increased by times, low frequency resonance is generated, and the resonance enables the amplitude of low frequency sound waves to zoom, so that a satisfactory bass effect can be obtained by small loudspeakers or the small sound box, and the size of the whole sound box is substantially reduced.

Description

technical field [0001] The invention relates to a sound box, in particular to a double-membrane resonant sound box with two ends. Background technique [0002] In recent years, with the development of the Internet and smart phones, people have higher and higher requirements for the sound quality of audio playback, and require smaller and smaller volume and weight. 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); These loudspeakers of public technology, either volume is too big, or bass sound reproduction effect is not good. Portable speakers and desktop speakers with ideal playback effects cannot be made with small speakers and small speakers. Contents of the invention [0003] In order to solve the problem of poor bass playback effect of existing sound boxes, the object...
