Problems solved by technology
[0003] With the continuous development of digital camera technology, the body of the camera is often small and light, which is easy to cause hand shake, resulting in blurred images
The following three situations are likely to produce blurred images: 1. When shooting with a long focus, since the long lens will amplify the amplitude of the camera, slight shaking will also cause greater blur, so the impact of hand vibration on the image clarity is greater than that of using wide-angle lens
2. Shooting in low-light environments. In low-light environments such as indoors and at dusk, the camera will adjust the shutter speed slower to increase the amount of light, so hand shake is more likely to occur.
These conditions can cause jitter, making the image blurred

Embodiment Construction
[0036] Please also see figure 1 and figure 2 , the first embodiment of the technical solution provides an elastic piece 100, which includes an integrally formed matching part 110, a first elastic part 120, a second elastic part 130, a first fixing part 140, a second fixing part 150 and a connecting first The fixed connection section 160 between the fixing part 140 and the second fixing part 150 .
[0037] The matching part 110 is used for fixed connection with the movable component of the voice coil motor. In this embodiment, the matching portion 110 is located between the first elastic portion 120 and the second elastic portion 130 . The mating part 110 is roughly in the shape of a rectangular sheet, which has a first side 111 extending along the width direction, a second side 112 opposite to the first side 111, a third side 113 extending along the length direction, and a second side 113 extending along the length direction. The fourth side 114 opposite to the three sides...

The invention relates to a spring plate comprising a matching part, a connecting part, a first elastic part, a second elastic part, a first fixed part and a second fixed part, wherein the first elastic part and the second elastic part are respectively connected with the matching part and the connecting part; and the first fixed part and the second fixed part are formed by extending both sides of the connecting part, and an avoidance port is arranged on the matching part. The invention also relates to a voice coil motor adopting the spring plate.
Description
technical field [0001] The invention relates to optical anti-shake technology, in particular to a voice coil motor applicable to optical anti-shake and a shrapnel applied to the voice coil motor. Background technique [0002] The camera module uses the shutter to control the length of time that the light is projected to the image sensor. For example, when the shutter speed is 1 / 2 second, it means that the time for the image sensor to receive light is 1 / 2 second. If within this 1 / 2 second When the same beam of light moves on the image sensor due to shaking, the image sensor will record the movement track of the light, making the captured photo blurred. In order to compensate for the light offset caused by shaking, camera modules using image stabilization systems to prevent shaking began to appear in the 1990s. For details, please refer to the paper "Optical image stabilization for digital cameras" published by Cardani B. et al. in Control Systems Magazine, IEEE (Volume26, Is...
