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 may be executed by a device having a wound eccentric motor.

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

[0030] The types of control signals include positive control signals or negative control signals. 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, a device with a wound eccentric motor can receive a control signal, and the control signal can be input by a user or automatically generated by the device with a wound eccentric motor according to specific conditions, for example: The wire eccentric motor device is a small motor used to generate vibration in the mobile phone. Users can...

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 may be executed by a device having a wound eccentric motor.

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

[0043] The types of control signals include positive control signals or negative control signals. 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 the cam and the center of gravity of the cam at the same time. E.g:

[0045] In practical applications, the fixing or unlocking of the rotating shaft of the wound eccentri...

Embodiment 3

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

[0063] The apparatus in this embodiment can be run on equipment with an eccentric motor.

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

[0065] The types of control signals include positive control signals or negative control signals. 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 rotating shaft 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 to control the sig...

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, and 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. One of the most important functions of eccentric motors is to enable the device to vibrate with a certain amplitude and frequency. For example, in mobile terminals such as mobile phones, it can realize the vibration reminder function of incoming calls. Among them, the micro eccentric motor; 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 intensity when using a massage chair. ...
