Specific embodiment

Before describing the embodiments in more detail, it should be understood that the utility model is not limited in the application hereafter or attached drawing Described in detailed construction or arrangement of elements.The utility model can be the embodiment that other manner is realized.Moreover, it should it manages Solution, wording used herein and term are solely for description purposes, should not the explanation of being construed as limiting property." packet used herein Include ", "comprising", the similar wording such as " having " meant comprising items listed thereafter, its equivalent and other additional things.It is special It is not that, when describing " certain element ", the utility model does not limit the quantity of the element as one, can also include more It is a.

As shown in Figure 1, this specification introduces technical scheme of the present invention by taking mobile phone protecting case 10 as an example.It should be appreciated that The present invention is also applied to other electronic device protection cases, such as protective case for panel computer 10.Mobile phone protecting case 10 includes shell Body 12, housing 12 enclose the storage tank 16 that can house mobile phone 14.Housing 12 corresponds to acoustical device (receiver, the microphone of mobile phone 14 And loud speaker) equipped with acoustic holes position 18.

Fig. 2 is the partial enlarged view at the A of Fig. 1, and housing 12 further includes the mesh members 20 of covering acoustic holes position 18, netted Component 20 prevents foreign objects to enter to stop foreign objects (such as greasy dirt, oil smoke or syrup) into acoustic holes position 18 Or the waterproof and dustproof structure surface inside mobile phone 14 is remained in, such as waterproof screen cloth surface.And the sound sent out from mobile phone 14 Or the sound inputted from the external world to mobile phone 14 can penetrate the mesh members 20.

More specifically, mesh members 20 are the acoustics screen cloth of reticular structure, possess fine hole position, can stop ash Dirt, and using the intrusion of tension liquid barrier (such as water, oil).

Acoustics screen cloth with micropore position can obstruct foreign objects, can also hinder the transmission of sound to a certain degree.It is preferred that , the acoustic resistance of the acoustics screen cloth of the utility model is less than 50 Rayleighs (Rayls), to meet the needs of being installed on acoustic holes position 18. Accordingly, if 18 corresponding acoustical device of acoustic holes position is microphone, microphone sensitivity loss is less than 0.5DB/KHZ.If acoustics 18 corresponding acoustical devices of hole position are loud speakers, then loudspeaker sensitivity loss is less than 0.5DB/KHZ.If acoustic holes position 18 corresponds to Acoustical device be microphone, then sensitivity of microphone loss be less than 0.5DB/KHZ.

It should be understood that this only as the preferred embodiment of the utility model, in other embodiments, acoustic resistance also may be used To be more than 50 Rayleighs, the utility model does not limit this, as long as not stopping voice transmission.

In the present embodiment, the aperture of acoustics screen cloth is less than 40 μm, such as between 10 μm to 40 μm.Preferably, acoustics The aperture of screen cloth is less than 30 μm, such as in 20um between 30um.

In the present embodiment, the thickness of acoustics screen cloth is less than 100 μm, it is preferred that the thickness of acoustics screen cloth is less than 50 μm.

In the shown embodiment, it is the acoustic holes position 18 for the loudspeaker position that corresponding mobile phone 14 is covered with mesh members 20 For, it should be appreciated that this is only as an embodiment of the utility model.In other embodiments, mesh members 20 The acoustic holes position of corresponding microphone or receiver position can also be covered.Can be that whole acoustic holes positions are covered with above-mentioned mesh members 20, i.e. the quantity of mesh members can be consistent with the quantity of acoustic holes position.Alternatively, only acoustic holes position in part is covered with above-mentioned netted Component 20.

Mesh members 20 can be installed using various modes to acoustics hole site.For example, such as Fig. 3, mesh members 20 utilize double Face glue 22 is sticked in the inner surface of housing 12.Double faced adhesive tape 22 is set along the periphery of acoustic holes position 18, by the edge of mesh members 20 It is fixed on housing 12.

Such as Fig. 4, as an improvement, washer 24 is also provided in mesh members 20, by mesh members 20 and mobile phone Ontology 26 is spaced a distance.It is sticked specifically, mesh members have to the first surface 28 of shell inner surface and opposite In the second surface 30 of first surface 28.Washer 24 is arranged on the edge of second surface 30 so that when mobile phone protecting case install to When on mobile phone, second surface 30 and one preset distance of surface interval of mobile phone body 26.The setting of the preset distance causes to sound The obstruction that sound transmits can be reduced further..

In the fig. 4 embodiment, washer 24 extends along the continuous edge of the second surface 30 of mesh members 20, forms an envelope The annular closed.In other embodiments, which can not also be extended continuously, that is, form the annular with opening.

In the 5 embodiment of figure 5, the mesh members 20 are fixed in housing 12 in a manner of embedded.Specifically, Mesh members 20 include an edge 32 and the central portion 34 surrounded by the edge 32.Edge 32 is embedded to be fixed on housing 12 It is interior, and central portion 34 is located in acoustic holes position 18.This mode being embedded in housing 12 significantly increases its fixing intensity, because This effectively reduces amplitude of the mesh members 20 with acoustical vibration, therefore effectively reduces the influence to sound quality.

In conclusion the utility model provides a kind of mobile phone protecting case, mobile phone protecting case corresponds to each acoustical device of mobile phone (such as microphone, receiver and loud speaker etc.) protects acoustic holes position equipped with acoustic holes position, and equipped with mesh members so that extraneous The foreign objects such as water, oil will not be entered by acoustic holes position in mobile phone or the waterproof and dustproof structure of contact interior of mobile phone.Work as mobile phone It can be cleaned, be recycled when residue is excessive in the mesh members of protective shell.Therefore, the utility model can be very good Second protection is carried out to the acoustic holes position of mobile phone.In addition to this, the utility model is also applicable to the protection of other electronic devices In shell.

Concepts described herein may be embodied to other forms in the case of without departing from its spirit and characteristic.It is disclosed Specific embodiment should be considered as illustrative rather than restricted.Therefore, the scope of the utility model is by appended right It is required that it rather than is determined according to these descriptions before.It is any in the letter of claim and equivalency range Change should all belong to these the scope of the claims.
