Abstract

The invention provides a vibration assembly, a motor control method and a terminal. The vibration assembly comprises a linear motor, a detection circuit and a control circuit, wherein the linear motorcomprises a stator and a rotor, a first pole plate is arranged on the stator, a second pole plate is arranged on the rotor and can form a capacitor with the first pole plate, the detection circuit iselectrically connected with the control circuit and the first pole plate and the second pole plate of the linear motor and is used for detecting an electrical parameter value and energization time ofthe linear motor under the condition of rotor vibration and transmitting the energization time and the electrical parameter value to the control circuit, and the control circuit is electrically connected with the detection circuit and the rotor of the linear motor and is used for adjusting the vibration amplitude of the rotor according to the energization time and the electrical parameter value.Therefore, the vibration amplitude of the rotor can be adjusted according to the electrical parameter value and the energization time of linear motor under the vibration condition of the rotor, and the vibration control flexibility of the liner motor can be improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to a vibration component, a motor control method, and a terminal. Background technique [0002] The terminal can generate vibration by controlling the vibration of the linear motor, so that the user can obtain a good tactile (Haptic) experience. At present, a high-voltage driver chip and a specific vibration waveform are generally used to drive the linear motor to generate a strong vibration, so that the user can obtain a tactile sensation close to that of a physical button. [0003] In the above solution, the driving voltage and vibration waveform of the high-voltage driving chip are predetermined. It can be seen that the flexibility of the existing linear motor control method is relatively low. Contents of the invention [0004] Embodiments of the present invention provide a vibrating component, a motor control method and a terminal to solve...
