Abstract: Provided is a button assembly, a terminal device, and a control method. The button assembly is for electrical connection to the terminal device and includes a base body with a through-hole, a touch assembly movably connected therein, and a vibration assembly in contact with the touch assembly. The touch assembly is exposed on one side of the through-hole and is configured to detect press information. The vibration assembly includes a base plate that supports the base body and encloses to form accommodating space, and a piezoelectric vibration portion on the base plate corresponding to the accommodating space. The accommodating space is in communication with the through-hole. One end of the touch assembly facing the vibration assembly is in the accommodating space and is connected to the piezoelectric vibration portion or the base plate. The button assembly enables the user to obtain diversified tactile feedback when pressing the touch assembly.

Abstract: Embodiments of the present disclosure provide a tactile feedback system for a terminal device. The tactile feedback system includes: at least one pressing portion which is disposed in the through hole and partially exposed out of the middle frame; at least one pressure sensor which is fixed on an inner side of the at least one pressing portion and is in one-to-one correspondence with the at least one pressing portion, and is configured to collect pressure parameters generated after the at least one pressing portion is pressed; and a tactile feedback vibrator configured to perform corresponding vibration feedback drive according to the pressure parameters collected by the at least one pressure sensor. Compared with the prior art, the tactile feedback system of the present disclosure can save installation space, adapt to multiple scenarios, and provide a good user experience.
