Embodiment 1

[0027] Embodiments of the present invention provide a method for controlling vibration intensity, such as figure 1 shown, including:

[0028] The method flow described in this embodiment can be executed by a device having a wound-type eccentric motor.

[0029] Step 101, detecting the type of the received control signal.

[0030] Wherein, the type of the control signal includes a positive control signal or a negative control signal, the positive control signal is used to trigger the device to increase the vibration intensity, and the negative control signal is used to trigger the device to reduce the vibration intensity.

[0031] Specifically, in this embodiment, the device with a wound-type eccentric motor can receive a control signal, and the control signal can be input by the user or automatically generated by the device with a wound-type eccentric motor according to specific conditions, for example: with a wound The device of the linear eccentric motor is a small motor us...

Embodiment 2

[0040] Embodiments of the present invention provide a method for controlling vibration intensity, such as image 3 shown, including:

[0041] The method flow described in this embodiment can be executed by a device having a wound-type eccentric motor.

[0042] Step 301, detecting the type of the received control signal.

[0043] Wherein, the type of the control signal includes a positive control signal or a negative control signal, the positive control signal is used to trigger the device to increase the vibration intensity, and the negative control signal is used to trigger the device to reduce the vibration intensity.

[0044] In this embodiment, when the device is not triggered by the control signal, the rotating shaft of the wound eccentric motor is fixed on the slot of the cam, and the slot passes through the center of circle and the center of gravity of the cam at the same time. E.g:

[0045] In practical applications, the rotation shaft of the wound eccentric motor c...

Embodiment 3

[0062] Embodiments of the present invention provide a device for controlling vibration intensity, such as Figure 4 shown, including:

[0063] The device in this embodiment can operate on equipment with an eccentric motor.

[0064] The control signal detection module 41 is configured to detect the type of the received control signal.

[0065] Wherein, the type of the control signal includes a positive control signal or a negative control signal, the positive control signal is used to trigger the device to increase the vibration intensity, and the negative control signal is used to trigger the device to reduce the vibration intensity.

[0066] The intensity control module 42 is configured to increase the distance of the rotation axis of the eccentric motor relative to the center of gravity of the cam if the received control signal is a positive control signal, wherein the increased distance is a specified value.

[0067] Further, the intensity control module 42 is also used t...

Abstract

The invention discloses a method and device for having control over vibration strength, and relates to the technical field of electromotor application. The method and device for having control over the vibration strength can achieve control over the vibration strength of a device in a low-cost mode. The method for having control over the vibration strength comprises the steps of (1) detecting the type of a received control signal, wherein the control signal comprises a positive control signal or a negative control signal; (2) increasing the distance between a rotary shaft of an eccentric electromotor and the gravity center of a cam when the received control signal is the positive control signal, wherein the increased distance is an assigned value; (3) reducing the distance between the rotary shaft of the eccentric electromotor and the gravity center of the cam when the received control signal is the negative control signal, wherein the reduced distance is an assigned value. The method and device for having control over the vibration strength is beneficial to having control over the vibration strength of the device with the eccentric electromotor.

Description

technical field [0001] The invention relates to the technical field of motor application, in particular to a method and device for controlling vibration intensity Background technique [0002] Eccentric motors are gradually being used in more and more devices. Among them, the most important function of eccentric motors is to enable devices to vibrate with a certain amplitude and frequency, for example: to realize the vibration reminder function of incoming calls in mobile terminals such as mobile phones The miniature eccentric motor among them; massage chairs and other physiotherapy equipment also massage and physiotherapy the human body through the vibration formed by the eccentric motor. [0003] In the application process of equipment equipped with eccentric motors, it is often necessary to control the amplitude of the equipment to meet the needs of different users for vibration intensity. For example, users often need massage strength when using a massage chair, that is,...
