Description of the drawings：
Fig. 1 is the front view of the utility model；
Fig. 2 is the vertical view of the utility model；
Fig. 3 is the sectional view along A-A in Fig. 1；
Fig. 4 is use state sectional view in the utility model.
Specific embodiment：
The utility model is further illustrated with reference to specific embodiments and the drawings.
As shown in Fig. 1-Fig. 3, the utility model is a kind of Baffle Box of Bluetooth, including：The module bodies 1 of bluetooth sounding and
The housing 2 being set in outside module bodies 1.
Module bodies 1 include：Stent 11, loud speaker 3, circuit board 4, interface 5 and switch 6.Wherein, the loud speaker 3,
Interface 5 and switch 6 are electrically connected on circuit board 4, form the bluetooth power amplifier of a routine, indigo plant is integrated in circuit board 4
Tooth transmission module.Interface 5 is a power interface, certainly, also can be by connecing for charging to the battery in circuit board 4
Mouth 5 is directly powered circuit board 4.The interface 5 is revealed by the side of stent 11.Interface 5 is adopted in the present embodiment
It is USB interface.Switch 6 is touch-pressure switch, for opening and closing circuit.
Stent 11 is used as supporting body, for the installation of above-mentioned bluetooth power amplifier.11 main body of stent is in a cylinder moulding,
Setting is there are one partition board 110 among it, so as to which stent 11 is separated into two spaces up and down.It is offered on partition board 110 several
Through-hole enables two spaces connection up and down, wherein being used to install loud speaker 3, circuit board 4, interface positioned at 110 space above of partition board
5th, switch 6, battery etc. are located at the space below partition board 110.
The pronunciation end (one side for setting vibrating membrane) of the loud speaker 3 is set up, its end of pronouncing is enabled to be located at stent
At 11 upper end opening.The module bodies 1 further include a bottom cover 8, which is sealed on 11 lower ending opening of stent, and
In being provided with a button 9 on bottom cover 8, which corresponds to the switch 6.By pressing button 9 come trigger switch 6, realization electricity
Road is turned on and off.
The outer rim of 11 upper end opening of stent is formed with an outward flange 111, which is used for module bodies
1 slip forms interference, this point can elaborate below.111 surface of outward flange is provided with rubber strip 7.
The housing 2 is in the sleeve-shaped coordinated with stent 11, and the outside of stent 11 is set in by the trepanning of lower end,
And the sound hole 20 is offered in the top surface of housing 2.Size, the quantity of sound hole 20 are according to circumstances set.
Since housing 2 is directly set in the outside of stent 11, so upper glide can be achieved between housing 2 and module bodies 1
It is dynamic, it is detached between housing 2 and module bodies 1 in use in order to prevent, the 2 lower end inner surface of housing is formed with one
Inward flange 21 is limited by slip of the interference between inside and outside flange 21,111 between housing 2 and module bodies 1.Such as
As shown in Figure 4, when relative movement is to maximum distance between housing 2 and module bodies 1, inside and outside flange 21,111 mutually forms
Blocking can not just continue opposite slide at this time between housing 2 and module bodies 1.
Since housing 2 is set on stent 11, so a space, the sky can be formed between 11 top surface of housing 2 and stent
Between be exactly the utility model sound chamber 10.Sound chamber 10 can change with the relative sliding position between housing 2 and module bodies 1.
As shown in figure 3, in this case, the spacing between inside and outside flange 21,111 is maximum, the space of sound chamber 10 is in minimum shape at this time
State.As shown in Figure 4, in this case, inside and outside flange 21,111 contacts with each other, and the space of sound chamber 10 is in maximum rating at this time.
Since loud speaker 3 is the top surface with stent 11, when loud speaker 3 starts sounding, sound is pushed up after 10 internal resonance of sound chamber by housing 2
The sound hole 20 in face is sent out, so the size sounding when sound chamber 10 changes, the sound quality finally passed out can also change.It is logical
Often, becoming larger with sound chamber 10, the stereophonic effect of sound quality is also just stronger, and user can play according to module bodies 1
Music type adjust the size of sound chamber 10, that is, shell 2 is pulled to be moved with module bodies 1, so as to adjust the size of sound chamber 10.
As noted previously, as being to realize to position by force of sliding friction between shell 2 and module bodies 1, rub to increase
Power is wiped, the inner surface that rubber strip 7 or the inward flange 21 can be provided on 11 surface of outward flange is provided with rubber strip 7.
Rubber strip 7 can enable the cooperation between shell 2 and module bodies 1 even closer, so that it is guaranteed that shell due to the toughness of itself
Between 2 and module bodies 1 in sliding process, it can stop any position in the range of stroke, and keep the state.Shell 2
It will not gradually glide under the effect of gravity.
It is to be limited by inside and outside flange 21,111 to be formed to the slip of module bodies 1 and shell 2 in above-described embodiment,
Other structures realization can also be used in it, for example, by using thread fitting, changes the size of sound chamber 10 by the feeding of screw thread.
Certainly, the foregoing is merely specific embodiment of the utility model, are not to implement to limit the utility model
Range, all equivalent change or modifications done according to construction, feature and principle described in present utility model application the scope of the claims, should all wrap
It includes in present utility model application the scope of the claims.
