Abstract

The present invention relates to the technical field of electronic devices, and discloses a motor vibration control method and apparatus. The method comprises: acquiring an input signal obtained according to a desired motor vibration curve; inputting a digital signal sequence of the input signal into an equalizer to obtain an output signal processed by an equalizer; and inputting the output signalto the motor to control vibration of the motor, wherein the equalizer is a digital filter constructed according to a damping coefficient zeta, a resonance frequency [omega]n, a preset system samplingrate fs, a preset damping coefficient [zeta]d and a preset cutoff frequency [omega]d of the motor. The motor vibration control method and apparatus provided by embodiments of the present invention have an advantage that an actual vibration effect of the motor can conform to a desired motor vibration curve.

Description

technical field [0001] The invention relates to the technical field of electronic equipment, in particular to a motor control method and device. Background technique [0002] With the rapid upgrading of hardware and related software applications, apart from the basic function of communication, smartphones continue to bring surprises to users in the process of visual, auditory experience and human-computer interaction, allowing mobile phones to be used in social, entertainment, learning and work. It has a profound impact on the daily life of individuals. [0003] With the technological development and evolution of the mobile phone industry and the improvement of users' professional level, the tactile experience is no longer just the auxiliary vibration of ringtones and message prompts. Gradually, the tactile experience began to be deeply integrated with the process of human-computer interaction, visual scenes and sound effects in applications, interpreting and developing new...
