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...
