Abstract

The present invention provides a method, a device and a storage medium for controlling the vibration frequency of a linear motor. The method for controlling the vibration frequency of the linear motor includes: defining the basic vibration waveform, the driving voltage waveform and the waveform splicing mode of the vibration frequency of the linear motor; calculating the duration of the specified basic vibration waveform; calculating the first coefficient of the driving voltage waveform; calculating obtaining the second coefficient of the driving voltage waveform; calculating the calculated voltage value of the driving voltage waveform according to the first coefficient and the second coefficient; comparing the calculated voltage value with the maximum output voltage value to obtain the vibration of the linear motor driven and a driving voltage waveform composed of a plurality of the driving voltage values; splicing the driving voltage waveforms, and outputting the driving voltage waveform of the basic vibration waveform. The present invention realizes precise control of the vibration frequency of the linear motor, improves the vibration effect of the linear motor, and provides users with a richer vibration experience.

Description

【Technical field】 [0001] The invention relates to the technical field of tactile perception, in particular to a method, device and storage medium for controlling the vibration frequency of a linear motor. 【Background technique】 [0002] As an electromagnetic induction transducer, linear motors are widely used in industrial production and daily use. With the advancement of technology and the improvement of people's quality of life, the application of linear motors in portable devices plays an increasingly important role. Linear motors can provide a rich vibration experience. At the same time, due to the size limitation of linear motors in portable devices, they are generally made very small. Then, how to precisely control the linear motor so that the linear motor can produce rich shock effects is an important problem that plagues signal design engineers. [0003] As we all know, a high-quality shock effect mainly depends on the amplitude and frequency of the vibration wavef...
