【Specific implementation mode】
Below in conjunction with drawings and embodiments, the utility model is described in further detail.
Please refer to Fig. 1-6, the utility model provides a kind of loud speaker 100, and the loud speaker 100 includes frame
20, it is fixed on the protecgulum 30 of the frame 20 and is set to the breathable barrier 10 of the protecgulum 30, correspondence opens up on protecgulum 30
There is acoustic aperture, loud speaker 100 is successively through 10 outside sounding of the acoustic aperture and the breathable barrier.The breathable barrier 10 includes
Top layer 1, bottom 2 annular in shape and sandwiched are fixed on the screen cloth 3 between the top layer 1 and the bottom 2.
The top layer 1 includes cricoid main part 101 and from 101 outwardly extending tearing portion 102 of the main part.It is described
The setting in tearing portion 102 removes the top when loud speaker 100 can be facilitated to be assembled to loudspeaker enclosure or other-end equipment
Layer 1.
The breathable barrier 10 further includes the layers of two-sided 40 being folded between the main part 101 and the screen cloth 3,
The main part 101 and the layers of two-sided 40 are detachably connected, and the main part 101 includes viscous with the layers of two-sided 40
Lower surface 101a, the upper surface 101b opposite with the lower surface 101a, the connection upper surface 101a and the following table connect
The medial surface 101c of the face 101b and lateral surface 101d opposite with the medial surface 101c；The main part 101 is equipped with extremely
A few designated port 100, the designated port 100 extend to the lateral surface 101d through the medial surface 101c and run through institute from top to bottom
State the upper surface 101b and lower surface 101a；The designated port 100 with closest to the tearing portion 102 of the designated port 100 it
Between distance no more than the main part 101 outer perimeter one third, preferably less than or equal to 1/5th.In this reality
It applies in example, the quantity of designated port 100 is 1, and is arranged close to tearing portion 102, and the designated port 100 is described in as can be seen from Figure 3
The junction of the tearing portion 102 and lateral surface 101d extends inwardly to the medial surface 101c.When taking top layer 1 off, tearing portion
102 stress along annular body portion 101 at designated port 100 through circumferentially gradually taking top layer off, and therefore, the external force for removing top layer is relatively free of
The structure smaller of designated port, and effectively avoid taking up layers of two-sided 40.In present embodiment, the top layer 1 is to take off paper.Certainly,
Its material and shape is without being limited thereto.
The bottom 2 is identical as 101 shape of the main part, structure annular in shape.More preferably, the top layer 1 is to the bottom
The orthographic projection in 2 direction of layer is overlapped with the bottom 2.
In present embodiment, the bottom 2 is foam.Certainly, material and shape are without being limited thereto.
Folded set of the screen cloth 3 is fixed between the top layer 1 and the bottom 2.2 phase of the i.e. described top layer 1 and the bottom
When in forming frame protection structure, being used to support the protection screen cloth 3, orthographic projection of the screen cloth 3 on the top layer 1 is located at
It in the top layer 1, and is not overlapped with the outer edge of the top layer 1, i.e. the edge of the screen cloth 3 is to contract so that part institute
It states and forms gap between top layer 1 and the part bottom 2, so that the fracture of wire at screen cloth edge is all housed in gap.
Above structure makes the screen cloth 3 after cross cutting, and the fracture of wire that the screen cloth 3 generates is by top layer 1 and the pressing packet of bottom 2
It wraps up in, avoids fracture of wire and fall off and fall into the terminal with the breathable barrier 10 and influence performance, to improve ventilative isolation
The reliability of part；Meanwhile because the screen cloth 3 is formed sandwiched package structure by top layer 1 and bottom 2, aesthetic appearance degree is more preferable.
More preferably, in order to reinforce the fixing intensity of the top layer 1, the bottom 2 and the screen cloth 3, institute is further increased
The structural stability of breathable barrier 10 is stated, between the screen cloth 3 and the top layer 1 and the screen cloth 3 and the bottom 2
Between be equipped with glue-line 41.Being fixedly connected for the two is realized by the glue-line 41, and structural stability is stronger.
In addition, being also sticked far from 3 side of the screen cloth for the bottom 2 is fixed with the adhesive linkage 42.The adhesive linkage 42
So that the breathable barrier 10 is preferably fixed on loud speaker 100, facilitate combination.
In present embodiment, the glue-line 41 and adhesive linkage 42 are double faced adhesive tape.Certainly, the glue-line 41 and adhesive linkage 42 be simultaneously
Without being limited thereto or other materials with adhesive property are made.
It is further preferred that the quantity of the designated port 100 can also be two and two or more, as shown in fig. 7, in this reality
With in novel another preferred embodiment, the designated port 100 includes two, is arranged at least between the two neighboring designated port 100
One tearing portion 102.When taking top layer 1 off, multiple tearing portions 102 while stress effectively promote efficiency of assembling.In the present embodiment
In, the other structures of loud speaker are similar with the embodiment of above-mentioned Fig. 1-6, and this will not be repeated here.
Compared with the relevant technologies, the breathable barrier of the utility model and the loud speaker with the breathable barrier will
The breathable barrier is arranged to include that the multilayered structures such as the top layer, screen cloth and the bottom are formed by stacking, and make described
Air bound off member is located between the top layer and the bottom,
Layers of two-sided is set between the annular body portion of top layer and screen cloth, since top layer and layers of two-sided are detachably connected,
By the way that designated port is arranged in main part and tearing portion adjacent position, when loud speaker is installed to loudspeaker enclosure or mobile terminal, only need
Top layer can be removed by applying certain dynamics in tearing portion, keeps layers of two-sided exposed, then by by layers of two-sided with it is right
The position of shell is answered to be adhesively fixed, you can to realize fixation of the loud speaker in terminal.Simultaneously because being provided with designated port, avoid
Entire breathable barrier is taken away into loud speaker, or peeling layers of two-sided etc. when removing top layer and causes speaker fail, is improved
The effective percentage of product, to improve the reliability of breathable barrier and loud speaker；Meanwhile because top layer and bottom are by the screen cloth
Screen cloth form sandwiched package structure, aesthetic appearance degree is more preferable.
The above description is only the embodiments of the present invention, and it does not limit the scope of the patent of the present invention, every
Equivalent structure or equivalent flow shift made based on the specification and figures of the utility model, is applied directly or indirectly in
Other relevant technical fields, are equally included in the patent within the scope of the utility model.
