Embodiment Construction

[0021] In order to describe in detail the technical characteristics of the present invention, the following preferred embodiments are given and described as follows in conjunction with the accompanying drawings, wherein:

[0022] Such as Figure 1 to Figure 2 As shown, the first preferred embodiment of the present invention describes a method for making a motor emit a specific audio frequency, which mainly has the following steps:

[0023] A) Acquiring the starting resistance time Ts of a motor 91 , the starting resistance time Ts is the time interval between the time point when the power is started and the time point when the rotor of the motor 91 starts to rotate. In practice, the starting resistance time Ts can be obtained directly by means of the actual operation experiment of the motor 91, generally between 0.1 ms (milliseconds) and 5 ms (milliseconds). to limit the scope of protection in this case.

[0024] B) Under the condition that the motor 91 is not running, input...

Abstract

The invention discloses a method for enabling a motor to send specific audio. The method comprises the following steps: firstly, obtaining starting resistance time of the motor, wherein the starting resistance time is a time interval from a time point for starting energization to a time point when a rotor of the motor starts rotating; under the condition that the motor does not rotate, inputting multiple continuous and one-by-one driving electric energy into the motor, wherein each driving electric energy continues for a preset duration time, the preset duration time is shorter than the starting resistance time, and a spacing interval is formed between every two driving electric energy; each driving electric energy is provided with a carrier with preset frequency. For realizing the method, the action of inputting the driving electric energy into the motor is performed by means of a device consisting of a control unit and a motor driving unit.

Description

technical field [0001] The present invention is related to the sounding technology of motors, in particular to a method and device for making motors emit specific audio. Background technique [0002] Common motors are operated for the purpose and function of driving. There is no technology to directly use the mechanism structure of the motor itself to produce sound without connecting a speaker. [0003] And existing electronic device, for example the electronic speed changer on the bicycle, when it wants to prompt the user's state, mostly shows with light-emitting element (LED) or display screen (LCD), or prompts the user with the loudspeaker sending prompting sound. In the way of using luminous parts or display screens, users may need to look down, or may be affected by sunlight or night and cannot see clearly; using speakers, it is necessary to arrange the installation position of the speakers and the electronic device for driving the speakers. [0004] Therefore, if the ...
