example 1

[0046] Assuming that the moving part 13 is a magnetically permeable structure, then, as Figure 5 As shown, the pressure adjustment assembly can also include a first magnetic part 14, the first magnetic part 14 is arranged in the inner cavity 110, and is arranged opposite to the moving part 13; wherein, the first magnetic part 14 is configured to apply Magnetic force to drive the moving part 13 to move.

[0047] In Example 1, the structure of the first magnetic part 14 may correspond to that of the moving part 13 , for example, when the moving part 13 has a ring structure, the first magnetic part 14 may also have a ring structure, which is not limited here.

[0048] Based on this, assuming that the first medium is gas and the second medium is liquid, then the following combination Figure 6a-Figure 6c The focusing process of the liquid lens in Example 1 will be described.

[0049] (1) In the natural state, no current is applied to the first magnetic member 14 (also can be un...

example 2

[0054] Assuming that the moving part 13 is a magnetically permeable structure, then, as Figure 7 As shown, the pressure adjustment assembly can also include a second magnetic part 15, which can be arranged outside the lens barrel 11 and opposite to the moving part 13; wherein, the second magnetic part 15 is configured to move toward the moving part 13 applies a magnetic force to drive the moving part 13 to move.

[0055] In this example 2, the mutual attraction between the electromagnet (that is, the moving part 13) and the ferrofluid (that is, the second magnetic attraction part 15) is utilized, and the moving part is controlled by controlling the second magnetic attraction part 15 (active ring) 13 (driven ring) moves up and down, when the moving part 13 moves up and down, the extrusion of the first medium or the second medium can make the flexible film 12 complete the switching of concave lens-plane mirror-convex lens, increasing the zoom range.

[0056] Wherein, the focus...

example 3

[0060] Please refer to Figure 8 , the pressure regulating assembly may further include a piezoelectric driving device 16 disposed in the inner cavity 110 to drive the moving member 13 to move through deformation.

[0061] In this example 3, the piezoelectric driving device 16 can be a piezoelectric element made of piezoelectric material, that is to say, in this example 3, the deformation characteristics of the piezoelectric material are used to realize the moving part 13 (that is, the driven Ring) up and down to achieve zoom effect.

[0062] It can be understood that general piezoelectric materials are divided into three categories according to the crystallization method. The first type is single crystal structure such as quartz; the second type is polycrystalline structure ceramics, such as barium titanate piezoelectric ceramics (BaTiO3), lead zirconate titanate series Piezoelectric ceramics (PZT); the third type of polymer piezoelectric materials such as polyvinylidene flu...

Abstract

The invention discloses a liquid lens and electronic equipment, and belongs to the field of camera shooting. The liquid lens comprises a lens cone, a flexible film and a pressure intensity adjusting assembly. The lens cone is provided with an inner cavity, the flexible film divides the inner cavity into a first accommodating cavity and a second accommodating cavity, the first accommodating cavity is filled with a first medium, the second accommodating cavity is filled with a second medium, and the refractive indexes of the first medium and the second medium are different; and the pressure intensity adjusting assembly is connected with the lens barrel, and the pressure intensity adjusting assembly is used for adjusting the pressure intensity in the first accommodating cavity and / or the pressure intensity in the second accommodating cavity, so that the flexible film deforms towards the first accommodating cavity or the second accommodating cavity.

Description

technical field [0001] The application belongs to the field of imaging, and in particular relates to a liquid lens and electronic equipment. Background technique [0002] In recent years, there are more and more electronic devices integrated with cameras, such as smart phones, Ipads, notebooks, etc., and people's demand for electronic devices integrated with high-resolution cameras is also increasing. Among them, in order to allow electronic equipment to obtain a better zoom effect and meet people's needs for micro-zoom cameras, a new type of lens (liquid lens) has been proposed in related technologies, which can achieve focusing by changing the liquid form or the refractive index of the liquid. . [0003] However, the liquid lens provided in the related art has the problem of unsatisfactory zoom effect when focusing. Contents of the invention [0004] Embodiments of the present application provide a liquid lens and an electronic device, which can solve the problem of un...
