Example

[0045] Example 1

[0046] Suppose the moving parts 13 are magnetic structural pieces, then, if Figure 5 As shown, the pressure emphasible component can also include a first magnetic member 14, and the first magnetic member 14 is disposed in the inner cavity 110, and is disposed opposite the moving member 13; wherein the first magnetic member 14 is configured to apply to the moving member 13. Magnetic force to drive the moving parts 13.

[0047] In this example 1, the structure of the first magnetic member 14 may correspond to the moving member 13, for example, when the moving member 13 is a ring structure, the first magnetic member 14 can also be a ring structure, which is not limited thereto.

[0048] Based on this, it is assumed that the first medium is a gas, the second medium is liquid, then combined below Figure 6A-Figure 6C The focus process of the liquid lens in this Example 1 will be described.

[0049] (1) In the natural state, no current is applied to the first magnetic ...

[0053] Example 2

[0054] Suppose the moving parts 13 are magnetic structural pieces, then, if Figure 7 As shown, the pressure-emphasis component can also include a second magnetic member 15, and the second magnetic member 15 can be disposed outside the lens barrel 11, and is disposed opposite the moving member 13; wherein the second magnetic member 15 is configured to move toward the moving parts. 13 Apply magnetic force to drive the moving parts 13 move.

[0055] In this example 2, the mutual attraction of the electromagnet (i.e., moving members 13) and the ferromagnetic fluid (ie, the second magnetic suctionater 15) is used to control the second magnetic suctionater 15 (active ring). 13 (from the rope ring), when moving up and down, the extrusion of the first medium or the second medium can cause the flexible membrane 12 to perform the switching of the concave lens-plane mirror-convex lens, increase the zoom range.

[0056] Here, the focusing process of the liquid lens given in...

Example

[0059] Example 3

[0060] Please refer to Figure 8 The pressure-emphasis module may also include a piezoelectric driving device 16, and a piezoelectric driving device 16 is disposed in the inner cavity 110 to move by a plurality of drive moving parts 13.

[0061] In this example 3, the piezoelectric driving device 16 may be a piezoelectric element made of a piezoelectric material, that is, in this example 3, the deformation characteristics of the piezoelectric material, to achieve the moving parts 13 (that is, The upper and lower movement of the ring), realizes the zoom effect.

[0062] It will be appreciated that the general piezoelectric material is divided into three major categories in crystallization, and the first type of single crystal structure such as quartz; second type is a polycrystalline ceramic such as barium titanate piezoelectric ceramics (Batio3), lead zirconate Piezoelectric ceramic (PZT); third type high molecular piezoelectric material such as polyvinylidene fl...

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...
