Specific embodiment
Below, with reference to accompanying drawing and specific embodiment, the present invention is described further：
Reference picture 1, a kind of miniature loudspeaker box described in the present embodiment, including housing 1 and the loudspeaker 2, circuit installed in the lower section of housing 1
Plate 3, guidance set 4 and telescopic resonance cavity 5.The telescopic resonance cavity 5 is connected with guidance set 4, housing 1 respectively.The loudspeaker 2
It is fixed on guidance set 4, and loudspeaker 2 are electrically connected with circuit board 3.
The housing includes 1 one outer cover bodies 11, a guard 12 and the mounting bracket 13 for installing the guard 12.
The outer surface of the outer cover body 11 is in circular arc planar, and its center offers the hole 14 that amplifies.The shape size in the hole 14 that amplifies
It is identical with the guard 12.
The inner hollow of the mounting bracket 13, and both ends open.The guard 12 is fixed on one end of mounting bracket 13.Peace
The end that guard 12 is installed on dress support 13 is convexly equipped with an annular wall 131 to surrounding.The annular wall 131 is interior with outer cover body 11
Surface is fixedly connected.The hole 14 that amplifies is completely covered the guard 12.The guard 12 is used to prevent the impurity such as dust from expansion
Sound hole 14 is entered into housing 1.
The guidance set 4 carries out guiding during stretching motion for the telescopic resonance cavity 5.The guidance set 4 includes that one connects
Fitting 41, the guide 43 of some first guides 42 and 1 second.First guide 42 is fixed on connector 41, described
Second guide 43 is fixed on the one end of telescopic resonance cavity 5, and second guide 43 is slidably matched with the first guide 42.
First guide 42 can be three to six.Each first guide 42 is in strip, and is respectively perpendicular the company
The surface of fitting 41 is set.A guide groove 420 is offered on each first guide 42 respectively.Second guide 43 is in annulus
Shape, is sleeved on the one end of telescopic resonance cavity 5.Quantity is convexly equipped with the periphery wall of second guide 43 to be led with described first
To the equal projection 430 of part 42.Each projection 430 respectively correspondingly coordinates with first guide 42.Preferably, each projection
430 are connected in a guide groove 420 respectively.Each projection 430 can be moved back and forth respectively along a guide groove 420.The circuit board 3
Be fixedly mounted in connector 41 towards on the surface of housing 1.
The telescopic resonance cavity 5 can be prior art, and such as its inner hollow, and perisporium is provided with some folding lines 51.
When the telescopic resonance cavity 5 is shunk so that its perisporium carried out along folding line 51 it is folding, so as to reduce flexible sympathetic response
