[0025] Embodiment 1

[0026] See also Figures 1 to 4, shown is an earphone in an embodiment of the present utility model, comprising an earplug portion 110 and an ear stem portion 120 connected to the earplug portion 110, the ear stem portion 120 having a cavity, a touch structure 200 is provided on a side of the ear stem portion 120 facing the human ear, the touch structure 200 is at least partially provided in the cavity, the touch structure 200 comprises a pressing member 210 and a flexible circuit board 220 electrically connecting the pressing member 210 and the control chip of the earphone 100, the outer surface of the pressing member 210 is inclined from one side of the ear stem portion 120 away from the human ear to the other side, a pressure sensing module 230 is provided on a side of the flexible circuit board 220 away from the pressing member 210, the pressing member 210 squeezes the pressure rod module so that the flexible circuit board 220 transmits a corresponding electrical signal to the control chip, so that the earphone 100 achieves a control effect corresponding to the electrical signal.

[0027] In this embodiment, the pressure sensing module 230 is installed on the flexible circuit board 220 through SMT, and the flexible circuit board 220 is connected to the printed circuit board. A piece of silicone (i.e., the pressing piece 210) is placed between the pressure sensing module 230 and the shell of the ear stem part 120. The silicone interferes and squeezes the shell of the ear stem part 120 to apply a pre-pressure to the pressure sensing module 230. When the shell of the ear stem part 120 is pressed, the deformation of the shell of the ear stem part 120 is transmitted to the silicone. After the silicone is deformed, the pressure applied to the pressure sensing module 230 will change (△P>0, △P is the pressure increment), thereby transmitting a signal to the control chip to achieve a control effect.

[0028] It can be understood that the outer surface of the pressing member 210 is tilted from one side of the ear stem portion 120 away from the human ear to the other side, so that it can adapt to the irregular curved surface of the shell. The pressure-sensitive touch on the irregular full-curved surface can be achieved by both positive pressure and side pressure, and its hardness is 65A.

[0029] Furthermore, a fixing groove is provided on the side of the ear stem portion 120 facing the human ear, and the pressing member 210 at least partially exposes the fixing groove. A reinforcing plate 231 is provided on the side of the flexible circuit board 220 facing the pressing member 210 , and the reinforcing plate 231 is fixedly connected to the pressing member 210 .

[0030] The pressing piece 210 is partially embedded in the reinforcing plate 231, and the embedding depth is 0.15 mm. An adhesive piece is provided on the side of the pressing piece 210 facing the reinforcing plate 231, and the pressing piece 210 is bonded to the reinforcing plate 231 through the adhesive piece. Positioning columns 121 are provided on both sides of the reinforcing plate 231, and a gap is provided between the positioning columns 121 and the reinforcing plate 231.

[0031] It can be understood that the pressing member 210 is fixed to the outside of the ear stem 120 through the fixing groove, and the positioning column 121 is provided to effectively fix, position and support the entire touch structure 200, thereby avoiding the influence of the printed circuit board on the pressure sense and making the spatial size more stable.

[0032] Specifically, an epoxy film is laid between the reinforcing plate 231 and the flexible circuit board 220, and the thickness of the epoxy film is 0.025 mm. The flexible circuit board 220 includes a first contact portion 221 and a second contact portion 222 formed by bending the contact portion, the first contact portion 221 and the second contact portion 222 form a pressure-sensitive area, the pressing member 210 is arranged outside the pressure-sensitive area, the pressure-sensitive module 230 is arranged in the pressure-sensitive area, and a gap is provided between the second contact portion 222, and the distance between the second contact portion 222 and the inner wall of the ear stem portion 120 is not less than 2.15 mm.

[0033] It is understandable that during the assembly process, the pressure sensing module 230 needs to first fit onto the inner wall of the shell of the ear stem portion 120 so that the back plane of the pressing member 210 can be parallel to the outer surface of the pressure sensing module 230, thereby structurally improving the pressure sensing performance. A gap is set between the pressure sensing module 230 and the second contact portion 222 to provide space for the pressure sensing module 230 to sense deformation when receiving a load force.

[0034] In a specific implementation, when the user needs to operate the earphone 100, the user touches the pressing piece 210 by hand to apply a load force, and the pressing piece 210 squeezes the reinforcing plate 231 of the flexible circuit board 220 inside the earphone 100, so that the flexible circuit board 220 generates a corresponding signal according to the applied load force and the touch frequency of the load force, and transmits the signal to the printed circuit board. The printed circuit board transmits the signal to the control chip, thereby realizing the control effect of the earphone 100 through the control chip.

[0035] Embodiment 2

[0036] This embodiment provides an earphone, which is different from the earphone in the first embodiment in that: there are two touch structures 200, which are respectively arranged on both sides of the ear stem part 120 of one earphone 100 or respectively arranged on the side of the ear stem part 120 of two earphones 100 facing the human ear.

[0037] When in use, the two sides of the ear stem portion 120 of the earphone 100 on one side can enable the operation of the earphone 100 to be completed with only one hand, which greatly reduces the simplicity of the earphone 100; and the ear stem portions 120 of the two earphones 100 are respectively arranged on the side facing the human ear, so that the earphone 100 has more control methods, thereby achieving more control effects.

[0038] To sum up, the earphones in the above embodiments of the utility model, by setting a touch structure on the ear stem part, enable the control operation of the earphones to be realized through the touch structure. Furthermore, the touch structure includes a pressing piece and a flexible circuit board electrically connecting the pressing piece and the control chip of the earphone. The outer surface of the pressing piece is set to be inclined so that it can adapt to the irregular arc surface of the shell. The pressure-sensitive touch on the irregular full-curved surface can be achieved by both positive pressure and side pressure. According to the characteristics of pressure-sensitive touch, the technical feature of realizing pressure-sensitive touch on special-shaped surfaces is developed and realized with the pressure-sensitive module as the guide.

[0039] The above-mentioned embodiments only express several implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
