The subject matter herein generally relates to a multi-lens module structure, and more particularly to a multi-lens module structure having a reduced size and improved magnetic interference prevention.
Dual-camera or three-camera modules are increasingly used in electronic devices. However, magnets in the lenses are prone to magnetic interference, which affects a focusing speed and accuracy of the lens. If a distance between adjacent lenses is increased to reduce magnetic interference, an optical axis distance of the two lenses is increased accordingly, which not only affects assembly precision of the two lenses, but also reduces an overlap of the images taken by the two lenses, thereby affecting a shooting performance of the lenses.
Implementations of the present disclosure will now be described, by way of embodiments, with reference to the attached figures.
It will be appreciated that for simplicity and clarity of illustration, where appropriate, reference numerals have been repeated among the different figures to indicate corresponding or analogous elements. Additionally, numerous specific details are set forth in order to provide a thorough understanding of the embodiments described herein. However, it will be understood by those of ordinary skill in the art that the embodiments described herein can be practiced without these specific details. In other instances, methods, procedures and components have not been described in detail so as not to obscure the related relevant feature being described. The drawings are not necessarily to scale and the proportions of certain parts may be exaggerated to better illustrate details and features. The description is not to be considered as limiting the scope of the embodiments described herein.
Several definitions that apply throughout this disclosure will now be presented.
The term “substantially” is defined to be essentially conforming to the particular dimension, shape, or other word that “substantially” modifies, such that the component need not be exact. For example, “substantially cylindrical” means that the object resembles a cylinder, but can have one or more deviations from a true cylinder. The term “comprising” means “including, but not necessarily limited to”; it specifically indicates open-ended inclusion or membership in a so-described combination, group, series and the like.
As shown in
As shown in
The connecting portion 31 includes a first surface 34 and a second surface 35. The first surface 34 is opposite the second surface 35. The first surface 34 is located in the first through hole 32, and the second surface 35 is located in the second through hole 33. In one embodiment, the antimagnetic structure 20 includes at least two antimagnetic plates 22. The antimagnetic plates 22 are respectively attached to the first surface 34 and the second surface 35. The antimagnetic plates 22 are used to prevent magnetic interference between the two lens modules 10 during operation.
As shown in
As shown in
In another embodiment, the antimagnetic plates 22 are replaced with an antimagnetic coating 24.
Specifically, as shown in
As shown in
In other embodiments, the antimagnetic plates 22 and the antimagnetic coating 24 can be applied at the same time between the two lens modules 10.
In another embodiment, the antimagnetic plates 22 and/or the antimagnetic coating 24 are applied surrounding the voice coil motors 12 of the lens modules 10. The antimagnetic plates 22 and/or the antimagnetic coating 24 prevent magnetic interference between the two lens modules 10 and prevent magnetic interference between the lens modules 10 and adjacent electronic components, such as an earpiece, a speaker, an antenna, or the like.
In other embodiments, the multi-lens module structure 100 may include three, four, or more lens modules 10, such that the antimagnetic structure 20 is located between each two adjacent lens modules 10.
Referring to
As shown in
The multi-lens module structure 100 not only prevents magnetic interference between the two lens modules 10 by providing the antimagnetic structure 20, the separation distance D1 between the two lens modules 10 is effectively reduced, thereby improving the photographing effect of the multi-lens module structure 100 and improving a miniaturization design of the multi-lens module structure 100.
The embodiments shown and described above are only examples. Even though numerous characteristics and advantages of the present technology have been set forth in the foregoing description, together with details of the structure and function of the present disclosure, the disclosure is illustrative only, and changes may be made in the detail, including in matters of shape, size and arrangement of the parts within the principles of the present disclosure up to, and including, the full extent established by the broad general meaning of the terms used in the claims.
