Embodiment Construction

[0018] Embodiments of the present application are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals designate the same or similar elements throughout. The embodiments described below by referring to the figures are exemplary, and are intended to explain the present application, and should not be construed as limiting the present application.

[0019] The embodiment of the present application aims at using a fixed frequency to drive the motor to vibrate. Due to the difference of the motor monomer, the aging of the components, the drop of the mobile device and other factors, there are differences in the vibration of different motors, and the vibration of the same motor in different time periods exists. The difference affects the vibration feedback effect of mobile devices and affects the user experience. A motor control method is proposed.

[0020] The motor control method provided by the emb...

Abstract

The present application provides a motor control method, device, electronic device and storage medium, belonging to the field of electronic technology. The method comprises the following steps: acquiring a current first falling state of the mobile device; Acquiring a current driving frequency of a motor in the mobile device if the first falling state of the mobile device satisfies a preset condition; Determining each candidate driving frequency corresponding to the motor according to the current driving frequency and the preset error range; Sequentially driving the motors at each candidate driving frequency to obtain acceleration values of the mobile device at each candidate driving frequency; A target drive frequency of that motor is determine based on the acceleration value of the mobiledevice at each candidate drive frequency. Thus, the motor control method realizes the automatic calibration of the driving frequency of the motor when the driving frequency of the motor and the resonant frequency do not match, ensures the consistency of the motor vibration quantity, improves the vibration feedback effect of the mobile device, and improves the user experience.

Description

technical field [0001] The present application relates to the field of electronic technology, and in particular to a motor control method, device, electronic equipment and storage medium. Background technique [0002] With the continuous development of science and technology, various mobile devices are constantly being introduced, adapting to people's various needs and bringing great convenience to people's lives. Vibration feedback is a very common way of human-computer interaction in mobile devices, such as incoming call reminder, information push, alarm, tactile feedback, etc. [0003] Vibration feedback is generally achieved through motor vibration. A linear resonant motor consists of a spring, a magnetic mass and a coil. Springs suspend the coil inside the linear resonant motor, and when current flows through the coil, the coil generates a magnetic field. The coil is connected to a mass with magnetism. When the current flowing through the coil changes, the direction ...
