Abstract
A haptic vibration device includes a stator assembly, a vibrator assembly, and a touch-control assembly. The touch-control assembly can detect a pressing information in a first direction. The stator assembly includes a fixing frame assembly, and a magnetic circuit system fixed to the fixing frame assembly and having a magnetic gap. The vibrator assembly includes a shell elastically connected to the fixing frame assembly and provided outside the magnetic circuit system, and a solenoid assembly located in the magnetic gap. The magnetic circuit system can drive the solenoid assembly to reciprocate in a second direction with an angle to the first direction. A terminal and a control method are provided. The haptic vibration device can reduce the effect of the driving force in the non-pressing direction on the whole device, and has small space requirement for the terminal device in the pressing direction, and is suitable for various terminal devices.
