[0027] The embodiments of the utility model disclose an anti-mistouch key structure, earphones and hearing aids, which are used to solve the technical problem that conventional touch keys are prone to mistouch during use, causing inconvenience to users.

[0028] To help those skilled in the art better understand the present invention, the present invention is further described below in conjunction with the accompanying drawings and specific embodiments. Obviously, the embodiments described are only a portion of the present invention, not all of the embodiments. All other embodiments derived by those skilled in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0029] See also Figures 1 to 5 , an embodiment of the utility model provides an anti-accidental-touch key structure, comprising a housing 1, a keycap 2 and a trigger switch;

[0030] The trigger switch is installed inside the housing 1, and the central portion of the keycap 2 is elastically installed on the end of the housing 1. The central portion of the keycap 2 is connected to a pressing portion 4 extending into the housing 1 and used to press the trigger switch;

[0031] When the center portion of the keycap 2 is pressed, the pressing portion 4 presses against the trigger switch.

[0032] In the above design, only when the user presses the center of the keycap 2 can the pressing portion 4 connected to the keycap 2 press against the trigger switch to trigger a specific function. If the user accidentally touches the periphery of the keycap 2, the center of the keycap 2 is not subjected to sufficient force, and the pressing portion 4 cannot press against the trigger switch. This design effectively prevents users from accidentally pressing keys, greatly improving user convenience.

[0033] Furthermore, an elastomer 3 is provided at the end of the shell 1 in this embodiment, and an avoidance hole 301 is opened in the center of the elastomer 3. The central part of the keycap 2 protrudes toward the shell 1 to form a contact portion 201, and the contact portion 201 abuts against the surface of the elastomer 3. The top of the pressing portion 4 passes through the avoidance hole 301 and is fixedly connected to the contact portion 201.

[0034] In addition, the elastic body 3 in this embodiment is substantially fixed in a suspended manner on the housing 1 , thereby tending to move the keycap 2 toward the outside of the housing 1 .

[0035] It should be noted that when the center of the keycap 2 is pressed, the contact portion 201 presses downward on the surface of the elastic body 3, causing the elastic body 3 to undergo a certain elastic deformation. Simultaneously, the pressing portion 4 connected to the contact portion 201 presses downward on the trigger switch. When the external force acting on the center of the keycap 2 disappears, the elastic action of the elastic body 3 causes the keycap 2 to return to its original position, and the pressing portion 4 no longer presses on the trigger switch.

[0036] Furthermore, the abutting portion 201 in this embodiment is provided with a mounting hole 202 along its axial direction, and the top of the pressing portion 4 is fixed in the mounting hole 202 .

[0037] It should be noted that, through the above design, the connection between the pressing portion 4 and the abutting portion 201 can be made more compact.

[0038] Furthermore, in this embodiment, an adhesive layer is coated inside the mounting hole 202 , and the top of the pressing portion 4 is fixed inside the mounting hole 202 through the adhesive layer.

[0039] It should be noted that, through the above design, the connection between the pressing portion 4 and the abutting portion 201 can be tightened.

[0040] Furthermore, the elastic body 3 in this embodiment has multiple types, one of which is: the elastic body 3 is an elastic soft rubber layer integrally formed with the shell 1.

[0041] It should be noted that the housing 1 in this embodiment is specifically made of hard plastic material, and the elastic soft rubber layer and the housing 1 can be integrally formed by two-color injection molding, effectively eliminating the installation steps.

[0042] Another type is: the elastic body 3 in this embodiment is a metal spring fixed on the housing 1 .

[0043] It should be noted that this embodiment does not limit the specific type of the elastic body 3 , and designers can select a suitable elastic body 3 according to elasticity requirements.

[0044] Furthermore, the trigger switch in this embodiment includes a control circuit board 5 and a trigger bump 6 electrically connected to the control circuit board 5;

[0045] When the center portion of the keycap 2 is pressed, the pressing portion 4 presses against the trigger protrusion 6 .

[0046] It should be noted that the trigger bump 6 in this embodiment transmits an electrical signal to the control circuit board 5 when pressed.

[0047] Furthermore, a support base 7 is connected to the housing 1 in this embodiment, and the trigger switch is fixed on the support base 7 .

[0048] It should be noted that the above-mentioned support base 7 is specifically used to provide support for the trigger switch.

[0049] See also Figures 1 to 5 An embodiment of the present invention provides an earphone, comprising the above-mentioned anti-mistouch button structure.

[0050] It should be noted that in the headset of this embodiment, the pressing portion 4 connected to the keycap 2 can only press against the trigger switch to trigger a specific function when the user presses the center of the keycap 2. If the user accidentally touches the periphery of the keycap 2, the center of the keycap 2 is not subjected to sufficient force, and the pressing portion 4 cannot press against the trigger switch. This design effectively prevents users from accidentally pressing keys, greatly improving user convenience.

[0051] See also Figures 1 to 5 A hearing aid provided by an embodiment of the present invention includes the above-mentioned anti-accidental-touch button structure.

[0052] It should be noted that in the hearing aid of this embodiment, the pressing portion 4 connected to the keycap 2 can only press against the trigger switch to trigger a specific function when the user presses the center of the keycap 2. If the user accidentally touches the periphery of the keycap 2, the center of the keycap 2 is not subjected to sufficient force, and the pressing portion 4 cannot press against the trigger switch. This design effectively prevents users from accidentally pressing keys, greatly improving user convenience.

[0053] The above is a detailed introduction to the anti-mistouch key structure, earphones and hearing aids provided by the present invention. For those skilled in the art, based on the ideas of the embodiments of the present invention, there may be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
