The following application is described in further detail in conjunction with the accompanying figures 1-4.

The embodiment of the application discloses a mobile phone film.

Example 1:

referring to fig. 1, a mobile phone film comprises a glass layer 1 and a glue layer 2 adhered to one end of the glass layer 1, wherein the glass layer 1 is arranged in a cuboid shape, the glass layer 1 is arranged in a cuboid plate shape, and any two adjacent side surfaces of the glass layer 1 are in arc transition so as to be attached to a mobile phone screen. The glass layer 1 is preferably made of high-alumina glass with a thickness of 0.33mm, and in other embodiments of the present application, the glass layer 1 may also be made of medium-alumina glass or low-iron glass. Glue film 2 covers the whole surface of one end on the glass layer 1 thickness direction, and glue film 2 preferred adoption AB glue to the laminating of glass layer 1 and cell-phone screen is convenient for.

Referring to fig. 1, a clearance hole 11 is formed at one end of the glass layer 1 in the length direction, and the clearance hole 11 is formed along the thickness direction of the glass layer 1. When the mobile phone film is attached to the mobile phone, the clearance hole 11 is located at the mobile phone receiver and exposes the mobile phone receiver to the environment, so that the sound emitted by the receiver can be directly transmitted through the air, and the influence of the mobile phone film on the sound volume and the tone color is reduced. The clearance hole 11 penetrates through one end of the glass layer 1 in the length direction. Circular arc transition between the adjacent lateral walls of clearance hole 11 not only is favorable to reducing the dust and piling up between the adjacent lateral walls of clearance hole 11, is convenient for clean between the adjacent lateral walls of clearance hole 11 moreover. The hole wall of the clearance hole 11 and the side wall of the glass layer 1 are in arc transition, so that the probability that the joint of the hole wall of the clearance hole 11 and the side wall of the glass layer 1 is damaged due to collision is reduced.

In the experiment, when L =12.5mm and W =1.4mm, the glass layer 1 just can not cover and shield the earphone, so that the influence on the vibration of the earphone is reduced; when L =15.2mm and W =1.5mm, the size of the clearance hole 11 enables the mobile phone film to just pass a failure test and meet the production standard; preferred dimensions for clearance holes 11 are L =13.2mm, W =1.42 mm.

Referring to fig. 1 and 2, a circular imaging hole 12 is further formed in the glass layer 1, and the imaging hole 12 is formed in the thickness direction of the glass layer 1. When the mobile phone film is attached to the mobile phone, the camera hole 12 is located at the mobile phone camera and is concentrically arranged with the mobile phone camera. The hole wall of the camera hole 12 and one side of the glass layer 1, which is far away from the glue layer 2, are in arc transition. The camera is directly contacted with the outside due to the opening of the camera hole 12, so that the occurrence of imaging blurring caused by light loss in the glass layer 1 is reduced. The diameter of the camera hole 12 is D, wherein D is more than or equal to 3mm and less than or equal to 3.5mm, when D =3mm, the glass layer 1 just can not cover and shield the camera, so that the influence of the glass layer 1 on the camera quality is reduced; when D =3.5 mm. The size of the camera hole 12 enables the mobile phone film to just pass a destructive test, and the strength standard of the mobile phone film is met; the preferred size of the camera hole 12 is D =3.12 mm.

Referring to fig. 1 and 2, an arc surface 13 is arranged between the side surface of the glass layer 1 and the end surface of the glass layer 1 far away from the glue layer 2, so that discomfort or damage to the hand of a user caused by the edge of the glass layer 1 when the user uses a mobile phone is reduced. The projection width of the cambered surface 13 in the plane direction of the glue layer 2 is H, wherein H is more than or equal to 0.4mm and less than or equal to 0.5 mm. In actual production, H =0.4mm is a processing limit in consideration of cost; when H =0.5mm, the arc surface 13 just does not affect the normal display of the screen, and the influence of the arc surface 13 on the screen display is avoided.

The implementation principle of the embodiment 1 is as follows: the arrangement of the glue layer 2 is convenient for the adhesion of the mobile phone film and the mobile phone screen; due to the arrangement of the glass layer 1, the screen is prevented from being scratched due to friction between a hard object and the screen, and the probability of breakage of the screen when the screen is impacted is reduced; through opening clearance hole 11 on glass layer 1 for clearance hole 11 is just to the cell-phone earphone, makes the sound that cell-phone earphone department produced directly pass through the air and spreads, thereby has reduced the influence of cell-phone membrane to sound volume and tone quality.

Example 2:

referring to fig. 3 and 4, the difference between this embodiment and embodiment 1 is that the mobile phone film further includes a dust-proof piece 3, the dust-proof piece 3 covers and fills the clearance hole 11 and is fixedly connected to the glass layer 1, and one side of the dust-proof piece 3 away from the glass layer 1 is flush with the corresponding side of the glass layer 1. One side of the dustproof piece 3 close to the glue layer 2 is bonded with a dustproof adhesive strip 31, and the dustproof adhesive strip 31 is positioned at one end of the dustproof piece 3 far away from the glass layer 1. The arrangement of the dustproof adhesive strip 31 enables the dustproof piece 3 to be tightly attached to the earphone, so that the occurrence of dust entering the earphone is reduced.

Referring to fig. 3 and 4, the dust-proof member 3 is provided with a plurality of sound conduction holes 32, the plurality of sound conduction holes 32 are uniformly arranged on the dust-proof member 3 in an array, and the plurality of sound conduction holes 32 are all arranged along the thickness direction of the dust-proof member 3.
