The capacitive touch shoulder key comprises a touch chip 2 and a touch pad 3, wherein the touch pad 3 comprises more than two independent touch areas 31, each touch area 31 is respectively connected with the touch chip 2 to form a touch signal channel corresponding to the touch chip, and specifically, the schematic diagram takes the case that one touch pad 3 is provided with two independent touch areas 31 as an example.

In this embodiment, it should be noted that the capacitive touch shoulder key of this embodiment is suitable for mobile terminals such as mobile phones, tablet computers, and game machines equipped with shoulder keys.

Specifically, the capacitive touch shoulder key is a self-capacitance type capacitive touch shoulder key, and includes a touch pad 3 for sensing touch operation and forming a touch signal and a touch chip 2 for processing the touch signal. The touch panel 3 includes more than two independent touch areas 31, and each touch area 31 is connected to one excitation and sampling circuit of the touch chip 2, so as to form a touch signal channel corresponding to each touch area 31. When a touch event occurs, the touch event of the mobile terminal is judged by detecting the capacitance change of the electrode at the touch area 31. Specifically, the touch area 31 is connected to an excitation and sampling circuit of the touch chip 2 to realize the capacitance variation identification, and the capacitance of the touch area 31 depends on the sum of a first capacitance Cgnd between the touch area 31 and the system ground and a second capacitance Cbody between the human finger and the touch area 31; when a human finger touches a certain touch area 31 of the capacitance touch shoulder key, the third capacitance C detected by the touch chip 2 is Cgnd + Cbody; when the human finger leaves, the touch chip 2 only detects the first capacitance Cgnd. Based on the method, the detection and identification of the pressing and lifting of the human finger by the capacitive touch shoulder key can be realized. The capacitive touch shoulder key provided by this embodiment sets more than two independent touch areas 31 on the touch pad 3, so that one touch pad 3 can implement more than two touch signal channels, and a user can flexibly set the functions of different touch areas 31 according to the size of the palm and the length of the finger of the user. For example, only the touch area 31 which is most convenient to operate is provided with the corresponding function, so that the flexibility and the comfort level of operation are improved; or, the touch area 31 most convenient to operate is set as the function which is operated more frequently, and the less-used functions are set in the touch area 31 which is not convenient to operate, so that the flexibility and the function diversity of the capacitive touch shoulder key are improved; corresponding functions can be set for the combination of different touch areas 31, for example, an independent function is corresponding to two adjacent touch areas 31 when the touch areas are simultaneously touched, so that the functional diversity of the capacitive touch shoulder key is further improved.

Alternatively, the touch panel 3 is provided on an FPC (Flexible Printed Circuit).

Specifically, the installation difficulty of the touch pad 3 can be reduced by arranging the touch pad 3 on the FPC, so that the connection between the touch pad 3 and the touch chip 2 is easier to implement.

Optionally, the touch area 31 is formed by laying solid copper.

Specifically, the touch area 31 formed by laying solid copper is used as an electrode of a capacitor, and when a touch event occurs, the touch event of the mobile terminal is judged by detecting the capacitance change of the electrode of the touch area 31.

In one embodiment, each of the touch areas 31 corresponds to a preset first operation function.

In this embodiment, the first operation functions corresponding to different touch areas 31 may be the same or different. Specifically, when the first operation functions corresponding to the different touch areas 31 are the same, the user does not need to perform any setting, and the user can directly operate the most comfortable touch area 31 to realize the preset function, so that the adaptability and flexibility of the capacitive touch shoulder key are improved. When the first operation functions corresponding to different touch areas 31 are different, different function operations can be realized by operating different touch areas 31 of one touch pad 3, so that the functional diversity of the capacitive touch shoulder key is improved. The specific correspondence between the touch area 31 and the first operation function may be set according to actual needs, and the specific correspondence is not limited in this embodiment.

In one embodiment, the combination of two or more touch areas 31 corresponds to a preset second operation function.

In this embodiment, corresponding functions are set for different combinations of the touch areas 31, for example, an independent function is corresponding to when two adjacent touch areas 31 are touched simultaneously, so as to further improve the functional diversity of the capacitive touch shoulder keys. Those skilled in the art can understand that the second operation function may be the same as or different from the first operation function, and the specific correspondence between the combination of the touch area 31 and the second operation function may be set according to actual needs, and the specific correspondence is not limited in this embodiment.
