The touch module of claim 5, wherein the tapping detection area and the pressing detection area are rectangular and arranged in parallel, the first sub-sensors are provided with two sub-sensors and located at two ends of one side of the tapping detection area, which is far away from the pressing detection area, the second sub-sensors are provided with a plurality of sub-sensors and arranged in two rows, one row of the second sub-sensors is arranged at one side of the pressing detection area, which is close to the tapping detection area, and the other row of the second sub-sensors is arranged at one side of the pressing detection area, which is far away from the tapping detection area.

7. The touch module of any of claims 1-4, wherein the plurality of sensors further comprises at least one second sensor, and an end of the second sensor away from the touch pad is a free end that is suspended.

8. The touch module of claim 7, wherein the circuit board is rectangular, the first and second sensors are disposed in plural numbers, some of the first sensors are disposed at four corners of the circuit board, another part of the first sensors are disposed at intervals at a long side of one side of the circuit board, and the second sensors are disposed at intervals at a long side of the other side of the circuit board.

9. The touch module of any one of claims 1-4, further comprising a display module disposed between the touch pad and the sensor module, wherein the sensor module is fixed to the display module by gluing, and wherein the display module is fixed to the bracket by snapping; and/or the presence of a gas in the gas,

the touch module further comprises a reinforcing sheet, the reinforcing sheet is arranged between the sensor module and the bracket, and an avoidance concave part for avoiding the sensor is arranged on the reinforcing sheet; and/or the presence of a gas in the gas,

the bracket is configured to be fixed to a housing of the electronic device, or the bracket is configured to be integrally formed with the housing of the electronic device.

10. An electronic device, comprising the touch module of any one of claims 1-9.
