With the improvement of user requirements and the development of technologies, the performance of electronic equipment is better and better. Current electronic devices are typically configured with pressure keys. The pressure key can deform when pressed by a user, so that the sensor arranged in the electronic equipment can acquire the pressure key and the pressure key is finally converted into a control signal which plays a corresponding function. The pressure key is different from the traditional mechanical key, and the pressure key does not need to protrude out of the outer side surface of the shell of the electronic equipment, so that the appearance performance of the electronic equipment can be improved.

Because the pressure button triggers the sensor to collect signals through self deformation in the working process, the assembly of the pressure button needs to have the condition of being capable of deforming. In the current electronic device, a certain gap is required to be formed between the component where the pressure key is located and other adjacent components, so that the gap can allow the pressure key to deform after being pressed. But the gap is relatively easy to collect dust, eventually resulting in dust filling the gap. Under the condition, the gap does not exist, so that the pressure key cannot be normally pressed, the function of the pressure key is further influenced, and the problem that the pressure key of the conventional electronic equipment is unstable in work is seen.

In the embodiment of the present invention, the pressure button region may be a part of the housing 100 or the display module 200, so as to ensure the appearance performance of the electronic device. Of course, the shape and structure of the pressure key region may be various, as long as it can ensure that the pressure sensor 300 can deform and transmit the deformation to the inner cavity of the casing 100 when pressed.

When the user presses the pressure button region, deformation can take place for the pressure button region, because the pressure button region contains in casing 100 or display module assembly 200, consequently under the condition that deformation took place for the pressure button region, deformation also can take place for first assembly gap, and the emergence of pressure button region deformation can be guaranteed better for first assembly gap.

In the embodiment of the present invention, the first fitting slit is filled with the elastic member 400. The elastic member 400 may be elastic rubber, and the kind of the elastic member 400 may be various as long as it has elasticity.
