Specific embodiment

Below in conjunction with the attached drawing in the embodiment of the present application, technical solutions in the embodiments of the present application carries out clear, complete Site preparation description.It is understood that specific embodiment described herein is only used for explaining the application, rather than to the limit of the application It is fixed.It also should be noted that illustrating only part relevant to the application for ease of description, in attached drawing and not all knot Structure.Based on the embodiment in the application, obtained by those of ordinary skill in the art without making creative efforts All other embodiment, shall fall in the protection scope of this application.

Referring to Fig. 1, Fig. 1 is the structural schematic diagram of an embodiment of electronic device provided by the present application.

The electronic device of the present embodiment may include earpiece screen 10, glass panel 20, center 30, rear shell 40 and receiver 50.Earpiece screen 10 may be detachably retained on glass panel 20, and glass panel 20, center 30, rear shell 40 stack gradually Setting, receiver 50 are fixed in the space between center 30 and rear shell 40.

Electronic device includes smart phone, tablet computer, intelligent wearable device, digital audio & video players, electronic reading The electronic equipments such as device, handheld game machine and vehicle electronic device.Receiver 50 is widely used in electronic device, and receiver 50 is also named Earpiece, English are Receiver, and receiver 50 is a kind of in voiceless sound leakage (or high/low suction ring of 3.2 types by ITU standard) Under the conditions of audio electrical signal is converted into the electro-acoustic element of voice signal, during voice signal caused by receiver 50 sequentially passes through Earpiece screen 10 on frame 30 and glass panel 20 and enter human ear.

Glass panel 20 is exactly outermost layer glass of the display screen towards user, and 20 main function of glass panel is protection electronics Touch screen and display screen inside device, and play the role of decorative appearance.

Referring to Fig. 2, Fig. 2 is the section signal of an embodiment in 10 region of earpiece screen of electronic device provided by the present application Figure.

Specifically, center 30 includes bottom wall 31 and side wall 32, and side wall 32 extends from the edge bending of bottom wall 31, side wall 32 Can vertically bottom wall 31 it extend, side wall 32 can also be extended with substantially vertical bottom wall 31, and side wall 32 and bottom wall 31 can be individually Two assembling parts form, and side wall 32 and bottom wall 31 are also possible to the different component parts of an individual part.Glass panel 20 lids are located on bottom wall 31 and are connected on side wall 32, to complete the fixed installation to glass panel 20.Center 30 penetrates through bottom wall 31 offer intercommunicating pore 33, and receiver 50 is mounted on the side of the separate earpiece screen 10 of bottom wall 31.

The lateral surface of glass panel 20 offers accommodation groove 21 so that for placing earpiece screen 10, glass panel 20 is through accommodating The bottom of slot 21 offers through hole 22, and through hole 22 and intercommunicating pore 33 are interconnected, and the outer shape of accommodation groove 21 can be Circle, the outer shape of accommodation groove 21 are also possible to ellipse, and the outer shape of accommodation groove 21 is also possible to track type, accommodation groove 21 shape can also be the other shapes such as rectangular, it is not limited here.

The lateral surface shape of earpiece screen 10 is close or identical with the outer shape of accommodation groove 21, and earpiece screen 10 is placed in It sets in slot 21, and is connect by way of bonding with glass panel 20, such as double-sided adhesive or glue 70, to realize earpiece screen 10 purposes being detachably connected with glass panel 20.

Optionally, the lateral surface of earpiece screen 10 is no more than the lateral surface of glass panel 20, to avoid electronic device daily Earpiece screen 10 is directly scratched in use process, and influences the normal work of earpiece screen 10.The lateral surface of earpiece screen 10 can also be with It is flushed with the lateral surface of glass panel 20, to guarantee the globality of electronic device appearance.

Earpiece screen 10 offers sound outlet hole 11, sound outlet hole 11, through hole 22, intercommunicating pore 33 position correspond to each other and each other It is connected to, voice signal caused by receiver 50 sequentially passes through intercommunicating pore 33, through hole 22 and sound outlet hole 11 and enters human ear.

The material of earpiece screen 10 may include the metal materials such as stainless steel, aluminium or magnesium alloy, the material of earpiece screen 10 It may include PC (polycarbonate), ABS (acrylonitrile-butadiene-styrene copolymer), TPU (thermoplastic polyurethane elastomer) Or the plastic cement materials such as PMMA (polymethyl methacrylate).

The beneficial effect that the technical solution of the present embodiment is different from the prior art is: earpiece screen 10 is placed in accommodation groove 21 In, and connect by way of bonding with glass panel 20, glass panel 20, center 30, rear shell 40 are cascading, called Device 50 is fixed in the space between center 30 and rear shell 40.During the routine use of electronic device, earpiece screen 10 goes out Sound hole 11 can be lived by foreign matters from being blocked such as dusts, at this point, because earpiece screen 10 is to be connect in a manner of bonding with glass panel 20, institute Earpiece screen 10 can be taken out from accommodation groove 21 under the premise of not disassembling out other parts of electronic device.It is cleaning out After earpiece screen 10, earpiece screen 10 can be fitted into accommodation groove 21 from the lateral surface of glass panel 20, and viscous with glass panel 20 It connects in succession.Therefore the entire cleaning process of earpiece screen 10 is reduced, to improve the cleaning efficiency of earpiece screen 10.

Referring to Fig. 2, earpiece screen 10 includes mainboard 12, mainboard 12 offers sound outlet hole 11, and mainboard 12 is placed in accommodation groove In 21, and the bottom bonding connection of the side of mainboard 12 and accommodation groove 21, such as double-sided adhesive or glue 70.The outside of mainboard 12 Face is no more than the lateral surface of glass panel 20, and earpiece screen 10 is directly scratched during routine use to avoid electronic device, And influence the normal work of earpiece screen 10.The lateral surface of mainboard 12 can also be flushed with the lateral surface of glass panel 20, to guarantee The globality of electronic device appearance.Optionally, 12 elasticity of mainboard is connected on the side of accommodation groove 21, to enhance earpiece screen 10 Stability.

Referring to Fig. 3, further, earpiece screen 10 further includes side plate 13, side plate 13 extends from the edge of mainboard 12 with shape At deformation space 14, mainboard 12 passes through the end of side plate 13 and the bottom bonding connection of accommodation groove 21, such as double-sided adhesive or glue Water 70.Further, mainboard 12 is connected on the side of accommodation groove 21 by 13 elasticity of side plate, to enhance the stabilization of earpiece screen 10 Property.

Side plate 13 can by with mainboard 12 it is at right angle in a manner of from the edge of mainboard 12 extend, earpiece screen 10 can be borrowed at this time The interference fit between the deformation completion and accommodation groove 21 of mainboard 12 itself is helped, such as the material of earpiece screen 10 is Elastic plastic-rubber material Matter is made.

Side plate 13 can also by with mainboard 12 it is obtuse-angulate in a manner of from the edge of mainboard 12 extend.Specifically, side plate 13 from The edge of mainboard 12 extends to the direction away from deformation space 14, so that the angle between side plate 13 and mainboard 12 is obtuse angle.This When, sectional dimension of the side plate 13 on the direction from one end close to mainboard 12 to one end far from mainboard 12 is gradually increased, when When 13 elasticity abutting of side plate to the side of accommodation groove 21, the meeting of side plate 13 Stepwize Shrink on the direction of close deformation space 14, with The expansionary force of side plate 13 is incrementally increased until earpiece screen 10 and accommodation groove 21 reach an equilibrium state.
