[0031] Working principle: the device is provided with a vibration sensor (not shown in the figure), the magnet is an electromagnet for generating a magnetic field, the ball is directly installed on the module of the camera or the mobile phone and is composed of a rolling ball and a supporting ring. The axial movement of the ball bearing is realized by the position and movement of the ball, so as to eliminate the shaking of the camera or the mobile phone lens. The vibration sensor is used for detecting the shaking of the camera or the mobile phone, and the direction and amplitude signals of the shaking movement are transmitted to the magnet, and the ball bearing generates reverse movement to offset the shaking of the camera or the mobile phone;
[0032] The interaction of the magnetic field and the ball bearing is used to eliminate the shaking of the camera or mobile phone. When the vibration sensor detects the shaking of the camera or mobile phone, it will transmit these signals to the magnet through the circuit. Under the action of the magnetic field, the ferromagnetic balls in the ferromagnetic ball bearing are magnetized and produce adsorption force, so as to move a certain distance under the action of the magnetic field to offset the shaking of the camera or mobile phone. The moving distance and speed are determined by the current size and direction of the control magnetic field. With the change of the shaking direction and intensity of the camera or mobile phone, the ball bearing also moves accordingly. Therefore, the shaking effect of the camera or mobile phone is eliminated, and a more stable image is obtained. It can perceive the shaking of the photographic equipment, adjust the reverse shaking to balance the image, so as to provide clearer and more stable image shooting effect.
[0033] It should be noted that the motion state, motion trajectory, etc. of each mechanism of the device can be automatically controlled through numerical control program or PLC programming, and automatic start-stop and automatic operation can be realized by cooperating with position switches.
