Embodiment Construction

[0015] In order to facilitate the understanding of those skilled in the art, the structural principles of the present invention will be further described in detail below in conjunction with specific embodiments and accompanying drawings.

[0016] like figure 1 As shown, an image stabilization device, its image stabilization device includes a housing 1, a base 2, a coil carrier 3, an upper elastic piece 4, a lower elastic piece 5, a coil 6, a magnet 7, a circuit board 8, and the coil carrier 3 is installed on the base 2 , the shell 1 is covered on the base 2, and the upper and lower parts of the coil carrier 3 are respectively provided with an upper elastic piece 4 and a lower elastic piece 5. The elastic coefficient K of the upper elastic piece 4 is much smaller than that of the lower elastic piece 5.

[0017] like figure 1 As shown, four corners of the base 2 are provided with four protrusions 10 , the cross-section of the protrusions 10 is triangular, and the four corners...

Abstract

The invention discloses an image stabilization device comprising a housing, a base, a coil carrier, an upper elastic sheet, a lower elastic sheet, a coil, a magnet, and a circuit board. The coil carrier is installed on the base. The base is covered by the housing. The upper elastic sheet and the lower elastic sheet are arranged above and under the coil carrier separately. The elasticity coefficient K value of the upper elastic sheet is less than the elasticity coefficient K value of the lower elastic sheet. The image stabilization device of the invention can be used to perform movement compensation on images timely when the lens is subjected to translation to realize the anti-shake effect.

Description

technical field [0001] The invention relates to a small imaging device, in particular to an image stabilization device. Background technique [0002] Existing portable mobile phones with cameras, supported computers, and touch-control entertainment equipment, when taking pictures with hands, shake due to the shaking of hands, making the pictures taken blurred. The lens in the camera is generally placed on a coil carrier, elastic pieces are respectively arranged on the upper and lower sides of the coil carrier, and coils and magnets are arranged on the outer periphery of the coil carrier. By changing the size of the coil current, the purpose of lifting the coil carrier is achieved. There are two main aspects of blurred pictures caused by taking pictures at present, one, such as image 3 As shown, as the object moves, the object moves relative to the lens, causing the position of the image to move; Figure 4 As shown, when the object is not moving, due to hand shake, the len...
