Embodiment Construction

[0036] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0037] Such as figure 1 As shown, the generation of the motor drive signal usually passes through two major systems, namely the input system 10 and the control system 20 . The input system 10 means that when a certain event or request occurs, a signal will be sent out, which will contain all the information of the event, and the signal will be transmitted to the control system. A certain event may be an event that is not an instant operation such as the arrival of the alarm clock time, calendar reminder, etc., or it may be an instant operation such as the user pressing an APP or opening a certain video or game, or it may be a certain scene in the video. Non-manual operations such as incoming triggers, and even design-related operations such as user-defined motor vibration and duration, can be regarded as events. The function of the input system 10 is ...

Abstract

The present invention provides a signal generating method capable of accurately controlling a motor. The method includes the steps of generating a period compensation signal and a duration compensation signal, and can generate a control signal that is more in line with the actual vibration of the motor, so that the motor can be more accurately control.

Description

【Technical field】 [0001] The invention relates to the field of motor control, in particular to a signal generating method capable of precisely controlling a motor. 【Background technique】 [0002] Vibration has become an essential part of people's daily life, and most of them are used as a reminder source to remind users of the occurrence of a certain event. In addition to combining with audio and video to form complex vibration effects, simple vibrations also gradually have new functions. The reminder function is the simplest function, but as people's requirements become higher and higher, the function of simple vibration is also continuously expanded, such as relying on the duration of vibration to represent different levels of information. However, due to the limitations of existing motor technology and physical devices, it is impossible to precisely control the vibration duration of a vibration device with ordinary signals, especially for a very short time such as 10ms. ...
