Detailed description of the invention
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings.It is understood that herein
Described specific embodiment is used only for explaining this utility model, rather than to restriction of the present utility model.Further need exist for
Bright, for the ease of describing, accompanying drawing illustrate only the part relevant to this utility model rather than entire infrastructure.
Embodiment one
The axonometric chart of the dust guard of acoustical device in the mobile terminal that Fig. 2 provides for this utility model embodiment one.As
Shown in Fig. 2, the dust guard of the present embodiment can be used for the dust-proof, waterproof of acoustical device and promotes the sound of acoustical device
The situation of quality.This dust guard specifically includes: dustproof membrane body.
Described dustproof membrane body includes curved face part 210, for the sound chamber between described dustproof membrane body and acoustical device
Vibrate under the effect of middle air pressure.The material of dustproof membrane body is elastomer, causes described dustproof membrane body at acoustical device sounding
And when the air pressure in the sound chamber between acoustical device changes, in order to curved face part 210 occurs under the effect of described air pressure
Vibration.When acoustical device not sounding, the air pressure in this sound chamber recovers to normal value, and correspondingly, curved face part 210 is also restored to former
Shape.Exemplary, described elastomer is silica gel, i.e. described dustproof membrane body is silica gel thin film.Other elasticity can also be used
Body substitutes silica gel, prepares dustproof membrane body, such as, styrene analog thermoplastic elastomer, polyvinyl chloride-base thermoplastic can be used elastic
Body or dienes thermoplastic elastomer (TPE) etc. replace silica gel, prepare dustproof membrane body.
Dustproof membrane body also includes that installation portion 220, described installation portion 220 are positioned at the edge of described curved face part 210, and being used for will
Described dustproof membrane body is installed on supporting part or the acoustical device of mobile terminal.
Fig. 3 is the top view of the dust guard of acoustical device in the mobile terminal in this utility model embodiment one.Such as Fig. 3
Shown in, dustproof membrane body includes the first groove 310.By the described dustproof membrane body first surface relative with described acoustical device to
Internal setting first degree of depth that extends forms described first groove 310, and the bottom surface of described first groove 310 is curved surface.
Fig. 4 shows in the mobile terminal in embodiment one in the top view of the dust guard of acoustical device along A-A face
Sectional view.As shown in Figure 4, described dustproof membrane body also includes the second groove 320.The second surface relative by described first surface
Extending inward setting second degree of depth and form the second groove 320, the bottom surface of described second groove 320 is curved surface, described first recessed
Position between bottom surface and the bottom surface of described second groove 320 of groove 310 is curved face part 210, to guarantee that curved face part 210 has enough
Space vibrate.
The bottom surface of the first groove 310 and the angle of side are fillet, and, the bottom surface of described second groove 320 and side
Angle be fillet.Fillet design makes curved face part 210 more firm with the connection of installation portion 220, it is to avoid because of repeatedly vibration and
Curved face part 210 is caused to rupture with installation portion 220.
Exemplary, curved face part 210 is wavy.As shown in Figure 4, curved face part 210 includes three regions, and regional
Surface be cambered surface.Wherein, the depth capacity of first area 211 exceedes the depth capacity of second area 212, and first area
The bottom surface of 211 is the concave surface of arc.The bottom surface of second area 212 is the convex surface of arc, and, the 3rd region 213 and the firstth district
Territory 211 is symmetrical about the axis of curved face part 210, thus, make whole curved face part 210 present wavy.The shape of curved face part 210
Being not limited to wavy, can be designed to other according to actual needs and be capable of air pressure level and die down, curved face part 210 vibrates width
Degree becomes the shape of big effect.
The technical scheme of the present embodiment, by using dustproof membrane body to replace the Air Filter of acoustical device, solves dust and blocks up
Live the problem mixing noise in the sound that Air Filter causes the acoustical device of mobile terminal to send.Meanwhile, dustproof membrane body sets
Some curved face part, vibration sounding under the effect of air pressure in the sound chamber between described dustproof membrane body and acoustical device, it is achieved
Bass frequency range, the Oscillation Amplitude of curved face part becomes big, makes up bass frequency range amplitude little, cause sound intracavity air pressure change the least and shadow
The defect of sound sound quality, meets the audio requirement of each frequency range.Waterproof function can also be realized, it is to avoid water is from acoustical device hole
It is flowed into inside mobile terminal, and damages internal circuit.

Exemplary, described reinforced sheet is polyethylene terephthalate sheet material or polycarbonate sheet.Reinforced sheet leads to
Cross injection molding manner to be integrated with described dustproof membrane bulk junction.The mode implemented is by by polyethylene terephthalate
The reinforced sheet 230 that sheet material or polycarbonate sheet are made is fixed in mould by fixing post, and this mould is dust-proof for being used for processing
The instrument of device.After fixing reinforced sheet 230, under the process conditions set, in mould, inject silica gel material, by note
After the mode moulded makes the dust guard that dustproof membrane body and reinforced sheet 230 are combined as a whole, by dust guard from mould point
From, position corresponding with fixing post on the installation portion 220 of dust guard leaves hole 410.
The mode being arranged in installation portion by reinforced sheet has multiple, however it is not limited to the mode that above-mentioned example is enumerated.All right
It is accomplished by the combination of reinforced sheet and installation portion.Setting is extended inward by least one surface of described installation portion
3rd degree of depth forms at least one cavity, is provided with described reinforced sheet in described cavity.
As it is shown in figure 5, with the side of dust guard as surface, the side along dust guard surrounding extends inward setting
Three degree of depth form a cannelure, arrange reinforced sheet in this cannelure, and unlike the sectional view shown in Fig. 5, using should
Mode does not fix hole corresponding to post 410 on installation portion 220.The mode that cavity is set is extended inward from the surface of installation portion
It is not limited to aforesaid way, it is also possible to be using the end face of installation portion or bottom surface as surface.The degree of depth extended inward by surface
Can also determine according to actual needs, can be to arrange by the cavity of the up/down perforation of end face to bottom surface, it is also possible to be set to not
Through cavity etc..
