A further object of the present invention is to provide a device for causing a motor to emit a specific audio, which can directly emit sound by the mechanism structure of the motor itself, thereby omitting the illuminating member or the display screen, and eliminating the need for a separate speaker, thereby saving Installation space and component cost.

In order to achieve the above object, the present invention provides a method for causing a motor to emit a specific audio, comprising the steps of: obtaining a starting resistance time of a motor, the starting resistance time being a time point from the start of energization until the rotor of the motor a time interval between the time points of the initial rotation, and a continuous, one-by-one, plurality of driving electrical energy input to the motor in a state in which the motor is not in operation, each of the driving electrical energy being continued for a predetermined duration, the predetermined duration It is shorter than the starting resistance time, and each of the driving electric energy is separated by an interval time; wherein each of the driving electric energy is accompanied by a carrier of a predetermined frequency.

By the above method, the sound can be directly emitted by the mechanism structure of the motor itself, and can be used to prompt the user. In addition, the illuminating member or the display screen can be omitted, and no additional speaker is required, which can save installation space and component cost.

In addition, in order to achieve the above object, the present invention also provides a device for causing a motor to emit a specific audio, comprising: a control unit; and a motor driving unit electrically connected to the control unit and electrically connected to a motor, The control unit is configured to control the motor driving unit to drive the motor; the motor corresponds to a starting resistance time, which is a time point from when the power is started until a time point when the rotor of the motor starts to rotate. a time interval; wherein, when driving, the control unit controls the motor drive unit to output a continuous and one-by-one plurality of driving power to the motor, each of the driving power sources continuing for a predetermined duration, the predetermined duration being shorter than the The starting resistance time is started, and each of the driving electric energy is separated by an interval time; wherein each of the driving electric energy is accompanied by a carrier of a predetermined frequency.

With the above structure, it is also possible to directly emit sounds by the mechanism structure of the motor itself, which can be used to prompt the user. In addition, the illuminating member or the display screen can be omitted, and no additional speaker is required, which can save installation space and component cost.

In order to explain the technical features of the present invention in detail, the following preferred embodiments will be described with reference to the drawings, wherein:

As shown in Figs. 1 to 2, a first preferred embodiment of the present invention describes a method of causing a motor to emit a specific audio, which mainly has the following steps:

A) The starting resistance time Ts of a motor 91 is obtained, which is the time interval between the time point at which the energization is started until the time when the rotor of the motor 91 starts to rotate. In practice, the starting resistance time Ts can be obtained directly by the actual operation experiment of the motor 91, generally between 0.1ms (milliseconds) and 5ms (milliseconds), which is used for example only. It is not intended to limit the scope of patent application in this case.

B) In the case where the motor 91 is not operating, a continuous and one-by-one plurality of driving electric power Dp is input to the motor 91, and each of the driving electric power Dp is continued for a predetermined duration Td, which is shorter than the starting resistance. The time Ts, and each of the driving powers Dp is separated by an interval time Ti; wherein each of the driving powers Dp is accompanied by a carrier Wc of a predetermined frequency. The frequency of the carrier Wc attached to the driving power Dp is between 200 Hz (hertz) and 10 kHz (kilohertz), and is audible to the human ear.

Therefore, when the driving power Dp is input to the motor 91, a coil (not shown) inside the motor 91 generates a magnetic field due to the input of the current, and the magnetic field can make the coil and the stator of the motor 91. Resonance occurs between the rotor (not shown) of the motor 91 and the rotor of the motor 91 (not shown), thereby forming a sound of a specific audio, wherein the coil, the stator and the rotor are well-understood and understandable components. Then show it in the schema. Since the predetermined duration Td of each of the driving electric power Dp is shorter than the starting resistance time Ts, it will end between the substantial rotation of the motor 91, and the rotation of the motor 91 will not be caused. As far as we can see, the technique of the present invention allows the motor 91 to emit a specific audio sound by resonance between its coil, stator and rotor when the motor 91 is not operating. As for the interval time Ti, it is related to whether the sound generated by each driving electric energy Dp input to the motor 91 makes people sound continuous, and the shorter the interval time Ti is, the more continuous the sound is, and in practice, the interval is The time Ti can be set to be less than the starting resistance time Ts. The less than the starting resistance time Ts is used for example only, and is not intended to limit the scope of the patent application. The setting of the starting resistance time Ts can also be used. Depending on the needs of the person.

In the first embodiment, the predetermined duration Td of each of the driving electric power Dp is the same, and each of the interval times Ti is also the same. Such a setting can be relatively simple in control. If the predetermined duration Td of each of the driving electric power Dp is to be different, an individual setting is required, which can be set as needed, but it is complicated. Similarly, each of the intervals Ti can be different depending on the requirements, but there are also complicated problems in setting.

In addition, in the first embodiment, the frequencies of the carriers Wc attached to the portion of the driving power Dp may be the same, and the frequencies of the carriers Wc attached to the remaining driving power Dp are different. Thereby, sounds of different frequencies can be sequentially emitted to form a melody that can be recognized by the user, such as a specific song melody or a specific prompt sound. Thereby, the user can make the motor 91 emit different melody or audio sounds by setting, so as to be used as a plurality of different sound signals for the user to recognize, thereby achieving the effect of prompting the user with different meaning messages.

As can be seen from the above, the technique of the present invention can directly emit sounds by the mechanism structure of the motor itself, and can be used to prompt the user. In addition, with the technology of the present invention, the illuminating member or the display screen can be omitted, and no additional speaker is required, which can save installation space and component cost.
