Abstract

The embodiment of the invention relates to the technical field of electronic devices and discloses a motor driving signal generating method which comprises a step of acquiring an acceleration segmentsignal, a constant segment signal and an attenuation segment signal, wherein the frequencies of the constant segment signal and the attenuation segment signal are smaller than that of the accelerationsegment signal, a step of connecting the acceleration segment signal and the constant segment signal and reserving a silent period without signal output between the braking segment and the constant segment to obtain a first motor driving signal, a step of adjusting the constant segment signal parameters of the first motor driving signal according to a vibration sensing demand and splicing the attenuation segment signal to the adjusted first motor driving signal to obtain a second motor driving signal, and a step of adjusting the attenuation segment signal parameters of the second motor driving signal to obtain the second motor driving signal with the highest braking efficiency and determining the second motor driving signal with the highest braking efficiency as a final motor driving signal. A low-frequency heavy tactile effect can be achieved when the motor vibration is controlled, and the fidelity of a specific tactile effect in scenes such as game and car central control screens isimproved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of electronic equipment, and in particular, to a method for generating a motor driving signal for providing tactile feedback, an electronic equipment, and a storage medium. Background technique [0002] Electrical signals with specially designed waveforms can be used to drive linear motors to complete vibrations that meet the tactile intensity requirements within a specified time. Due to the short duration, usually a few milliseconds to more than ten milliseconds, this electric signal driving the motor is also called a short signal. A short signal can be divided into two sections functionally. The function of the first section is to drive the motor to increase the vibration intensity from zero level to the level required by the tactile intensity in the shortest possible time; the function of the second section is to drive the motor Reduce vibration intensity from peak level to zero lev...
