Number it is converted into after voice signal, sound is passed.Acoustic aperture is offered at traditional loudspeaker respective hosts, by acoustic aperture by sound
Sound is well propagated, but traditional loudspeaker is generally mounted in main frame, and using a powerful loudspeaker, its tonequality
It is not good enough with volume.
For this problem, body proposes a kind of product back board structure for improving tonequality and volume.
Utility model content：
The purpose of this utility model is to overcome the deficiencies in the prior art to carry on the back there is provided a kind of product for improving tonequality and volume
Hardened structure.
In order to solve the above-mentioned technical problem, the utility model employs following technical proposals：Improve the production of tonequality and volume
Product back board structure, with a backboard, backboard is positively connected with main frame, and the back side offers air-vent, described backboard bottom shape
Into the cavity having for loudspeaker installation, it is provided between at least two loudspeakers, each loudspeaker and is arranged side by side simultaneously in inside cavity
And be connected in series, correspond on backboard at cavity and offer acoustic aperture；Pcb board is installed, loudspeaker is by leading on described backboard
Line is electrically connected with pcb board.
Furthermore, in above-mentioned technical proposal, described backboard includes：Back shroud and facing forward along the periphery of back shroud
The margin plate of extension is bent, the margin plate that back shroud bottom is formed is base.
Furthermore, in above-mentioned technical proposal, described acoustic aperture is opened on back shroud and base, and with cavity phase
Correspondence.
Furthermore, in above-mentioned technical proposal, described backboard is in inverted " t " type, when backboard is mutually assembled with main frame, main frame
Positioned at the centre of backboard inverted " t " type, loudspeaker is lived apart in the both sides of main frame.
Furthermore, in above-mentioned technical proposal, described loudspeaker is installed in cavity by the way that supporting plate is stable, is supported
Pass through screw locking between plate and cavity wall.
Furthermore, in above-mentioned technical proposal, it is fixedly connected between described supporting plate and loudspeaker, and in supporting plate
It is provided with the opening appeared for the vibrating diaphragm of loudspeaker.
Furthermore, in above-mentioned technical proposal, the power of described loudspeaker is：5w.
After adopting the above technical scheme, the utility model has the advantages that compared with prior art：This practicality
It is new in being provided with cavity in backboard, be connected in series in being provided with cavity between multiple loudspeakers, multiple loudspeakers, its tonequality
With volume more preferably, and by the structure setting of backboard, its sound effect is more preferably.
Brief description of the drawings：
Fig. 1 is structural representation of the present utility model；
Fig. 2 is upward view of the present utility model.
Embodiment：
The utility model is further illustrated with reference to specific embodiments and the drawings.
As shown in Fig. 1-2, the product back board structure of tonequality and volume is improved, with a backboard 1, the front connection of backboard 1
There is main frame, the back side offers air-vent, and the described bottom of backboard 1 is formed with the cavity 10 installed for loudspeaker 2, in cavity 10
Inside is provided between at least two loudspeakers 2, each loudspeaker 2 and is arranged side by side and is connected in series, and cavity 10 is corresponded on backboard 1
Place offers acoustic aperture 111；Pcb board is installed, loudspeaker 2 is electrically connected by wire with pcb board on described backboard 1.
Specifically, described backboard 1 includes：Back shroud 11 and the side for bending extension forward along the periphery of back shroud 11
Listrium 12, the margin plate 12 that the bottom of back shroud 11 is formed is base 12a.Acoustic aperture 111 is opened in back shroud 11 and base
On 12a, and it is corresponding with cavity 10.
In the present embodiment, backboard 1 is in inverted " t " type, when backboard is mutually assembled with main frame, and main frame is located at backboard inverted " t " type
Centre, the main frame that loudspeaker 2 is lived apart in the both sides of main frame, the present embodiment can be television set, and backboard 1 is used as television set
Backboard, display screen is provided with the front of backboard, and pcb board and other electric elements are provided between backboard 1 and display screen, when
So, according to different main frames, its pcb board and electric elements are different, but the loudspeaker 2 that main frame is connected is mounted on cavity
Interior 10.
Loudspeaker 2 is installed in cavity 10 by the way that supporting plate 21 is stable, and screwed lock is passed through between supporting plate 21 and cavity wall
Tightly, it is fixedly connected, and is provided with supporting plate 21 for opening that the vibrating diaphragm of loudspeaker 2 appears between supporting plate 21 and loudspeaker 2
