For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0036] like Figure 1 As shown, the present application provides an earphone, which includes a button assembly 100 and an ear shell 200. The earphone can be a head-mounted earphone, and the earphone can be configured with a call noise reduction function and / or an artificial intelligence noise reduction function, and at the same time, can also be configured with stereo surround and other functions.

[0037] Combination Figure 1 and Figure 2 It should be noted that a circuit board 300 is disposed inside the ear shell 200, an electronic button 310 is disposed on the circuit board 300, the button assembly 100 and the electronic button 310 are disposed opposite to each other, and the button assembly 100 will press the electronic button 310 when pressed.

[0038] like Figures 2 to 5 As shown, the key assembly 100 includes a buckling member 110 , a key body 120 and an elastic buffer pad 130 .

[0039] The buckle 110 is provided with an assembly hole 111 penetrating through both inner and outer sides thereof.

[0040] Specifically, the fastener 110 is used to fasten on the ear shell 200 to achieve the fixation of the button assembly 100 and the ear shell 200; wherein, the inner side of the fastener 110 refers to the side of the fastener 110 close to the inside of the ear shell 200, and the outer side of the fastener 110 refers to the side of the fastener 110 away from the inside of the ear shell 200.

[0041] Furthermore, the assembly hole 111 is a through hole, which is opened on the fastening component 110 and passes through both inner and outer sides of the fastening component 110 .

[0042] The button body 120 includes a pressing portion 121 passing through the assembly hole 111 , an anti-detachment portion 122 connected to the pressing portion 121 , and a trigger column 123 disposed at the inner end of the pressing portion 121 . The anti-detachment portion 122 is disposed opposite to the inner wall surface of the fastening member 110 .

[0043] Specifically, the pressing portion 121 is passed through the assembly hole 111, and the outer end of the pressing portion 121 is exposed from the buckle 110, so that the user can press it conveniently; the anti-detachment portion 122 is connected to the inner end of the pressing portion, and the anti-detachment portion 122 is arranged opposite to the inner wall surface of the buckle 110, so that the button body 120 can be prevented from falling off from the buckle 110; the trigger column 123 is connected to the inner end of the pressing portion 121, and when the pressing portion 121 is pressed, it can drive the trigger column 123 to move together.

[0044] It should be noted that the anti-detachment portion 122 and the inner wall surface of the fastening member 110 may be in contact with each other, or a gap may be reserved. By making the anti-detachment portion 122 face the inner wall surface of the fastening member 110, the button body 120 can be prevented from falling off the fastening member 110.

[0045] Furthermore, the cross-section of the assembly hole 111 is elliptical, and the cross-section of the pressing portion 121 is also elliptical. In this way, when the pressing portion 121 is inserted into the assembly hole 111, the pressing portion cannot rotate in the assembly hole 111, thereby maintaining the stability of the position of the button body 120 and the buckle 110.

[0046] Of course, in other embodiments, the cross-section of the assembly hole 111 and the cross-section of the pressing portion 121 may also be set to other shapes.

[0047] The elastic buffer pad 130 is arranged on the inner side of the button body 120. The elastic buffer pad 130 has a buffer portion 131 arranged opposite to the trigger column 123. A positioning blind hole 1311 for the trigger column 123 to pass through is provided on the side of the buffer portion 131 close to the button body 120. The trigger column 123 abuts against one end of the positioning blind hole 1311 away from the pressing portion 121.

[0048] Specifically, the buffer portion 131 protrudes from the inner wall surface of the elastic buffer pad 130, and a positioning blind hole 1311 is formed on the side of the buffer portion 131 close to the button body 120. The trigger column 123 is inserted into the positioning blind hole 1311, so that the elastic buffer pad 130 and the button body 120 can be positioned. In addition, the trigger column 123 abuts against one end of the positioning blind hole 1311 away from the pressing portion 121. When the pressing portion 121 is pressed, the force of the trigger column 123 will be directly transmitted to the buffer portion 131.

[0049] The elastic buffer pad 130 is made of silica gel, which has a better buffering effect.

[0050] In the button assembly 100 of the present invention, when the user presses the pressing portion 121, the trigger column 123 is driven to press the buffer portion 131, so that the buffer portion 131 presses the electronic button 310. If the earphone falls to the ground and the button assembly 100 happens to be in contact with the ground, the buffer portion 131 can also play a buffering role, reduce the destructive force, and reduce the force on the electronic button 310, thereby reducing the risk of the electronic button 310 being damaged.

[0051] In some embodiments, the button body 120 is provided with a first positioning groove 124 arranged around the trigger column 123 , and the elastic buffer pad 130 is provided with a positioning portion 134 penetrating into the first positioning groove 124 .

[0052] Specifically, the trigger column 123 is connected to the inner end of the pressing portion 121, and a first positioning groove 124 is formed around the trigger column 123. A positioning portion 134 penetrating into the first positioning groove 124 is provided on the side of the elastic buffer pad 130 close to the pressing portion 121. In this way, the positioning accuracy of the button body 120 and the elastic buffer pad 130 can be further improved.

[0053] like Figure 5 As shown, further, the inner side wall of the fastening member 110 is provided with a second positioning groove 112 , and the anti-slip portion 122 is disposed in the second positioning groove 112 and positioned and matched with the second positioning groove 112 .

[0054] It can be understood that the inner end of the assembly hole 111 passes through the groove wall of the second positioning groove 112. After the key body 120 is inserted into the assembly hole 111, at least a part of the anti-detachment part 122 can be set in the second positioning groove 112, thereby realizing the positioning of the elastic buffer pad 130 and the key body 120.

[0055] like Figure 5 As shown, in some embodiments, the periphery of the elastic buffer pad 130 has a positioning protrusion 132 extending toward the buckle 110 , and the positioning protrusion 132 is arranged around the anti-detachment portion 122 .

[0056] It can be understood that a positioning protrusion 132 is provided on the edge of the elastic buffer pad 130 on one side close to the pressing portion 121. The positioning protrusion 132 can be surrounded to form a positioning groove. The anti-slip portion 122 is inserted into the positioning groove and surrounded by the positioning protrusion 132. In this way, the elastic buffer pad 130 and the button body 120 can be further positioned.

[0057] Combination Figure 6 and Figure 7 The ear shell 200 is provided with a button hole 210; the circuit board 300 is arranged inside the ear shell 200, and the electronic button 310 is arranged opposite to the button hole 210; the button assembly 100 is passed through the button hole 210, and the buffer part 131 is arranged opposite to the electronic button 310.

[0058] In the earphone of the present invention, the electronic button 310 on the circuit board 300 is arranged opposite to the buffer part 131. When the user presses the pressing part 121, the trigger column 123 will be driven to squeeze the buffer part 131, so that the buffer part 131 squeezes the electronic button 310. If the earphone falls to the ground and the button assembly 100 happens to be in contact with the ground, the buffer part 131 can also play a buffering role, reduce the destructive force, and reduce the force on the electronic button 310, thereby reducing the risk of damage to the electronic button 310.

[0059] In some embodiments, the ear shell 200 is further provided with a snap-fit ​​hole 220 spaced apart from the button hole 210 , and the fastening member 110 is provided with a snap 113 penetrating through the snap-fit ​​hole 220 and snapping with the inner wall of the ear shell 200 .

[0060] Specifically, there are two snap-fit ​​holes 220, which are respectively arranged on both sides of the button hole 210, and the buckle 110 is provided with two buckles 113, which are respectively inserted into the two snap-fit ​​holes 220. In this way, the connection reliability between the buckle 110 and the ear shell 200 can be further improved.

[0061] Combination Figure 5 and Figure 6 Furthermore, a positioning platform 211 is provided on the hole wall of the button hole 210 , and the periphery of the elastic buffer pad 130 is arranged opposite to the positioning platform 211 .

[0062] It is understandable that the positioning platform 211 abuts against the peripheral portion of the elastic buffer pad 130. If the earphone falls to the ground and the button assembly 100 is in contact with the ground, the positioning platform 211 and the elastic buffer pad 130 can also prevent the button body 120 from being pressed excessively and damaging the electronic button 310.

[0063] Combination Figure 5 and Figure 7Furthermore, a positioning convex strip 133 which is positioned and matched with the inner wall of the positioning platform 211 is provided on a side of the elastic buffer pad 130 away from the button body 120 .

[0064] Specifically, the positioning platform 211 is an annular structure. The positioning convex strip 133 passes through the positioning platform 211 and contacts the inner wall of the positioning platform 211 , so as to realize the positioning of the positioning platform 211 and the elastic buffer pad 130 .
