Patent number: 9921386Abstract: A lens module includes a lens barrel having a top wall that has a bottom surface, and a lens group received by the lens barrel. The lens group includes a first lens adjacent to the top wall and a second lens attached to the first lens. A first complementary configuration is arranged between the first lens and the top wall of the lens barrel for ensuring a concentricity between the lens group and the lens barrel, and a second complementary configuration is arranged between the first lens and the second lens for ensuring a concentricity between the first lens and the second lens.Type: GrantFiled: March 12, 2015Date of Patent: March 20, 2018Assignee: AAC ACOUSTIC TECHNOLOGIES (SHENZHEN) CO. LTD.Inventors: Junjie Yan, Chuandong Wei, Chunhuan Fang, Lei Zhang, Liangwei Wan

Patent number: 9857551Abstract: A lens module includes a lens barrel, and a lens group received by the lens barrel. The lens barrel includes an first supporter, a second supporter extending vertically from the first supporter, and a receiving space formed by those supporters, the first supporter having a light aperture, the second supporter having an inner surface facing the receiving space. The lens group includes a first lens abutting against the inner surface of the second supporter, a second lens stacked on the first lens and abutting against the inner surface of the second supporter, a third lens stacked on the second lens and abutting against the inner surface of the second supporter, and a fourth lens stacked on the third lens and abutting against the inner surface of the second supporter, for ensuring the concentricity among the lenses and keeping the lens group coaxial with the lens barrel.Type: GrantFiled: March 13, 2015Date of Patent: January 2, 2018Assignee: AAC ACOUSTIC TECHNOLOGIES (SHENZHEN) CO., LTDInventors: Junjie Yan, Chuandong Wei, Chunhuan Fang, Lei Zhang, Liangwei Wan

Patent number: 9759885Abstract: A lens module includes a lens supporter, and a lens group received by the lens supporter. The lens supporter includes an aperture plate, a main body extending downwardly from the aperture plate and a receiving space formed by the aperture plate and the main body, the aperture plate having a light aperture, the main body having an internal surface facing the receiving space. The lens group includes a first lens abutting against the aperture plate for forming a first alignment accuracy, a second lens stacked on the first lens and keeping a distance from the internal surface of the main body, a third lens stacked on the second lens and keeping a distance from the internal surface of the main body, and a fourth lens stacked on the third lens and abutting against the internal surface of the main body.Type: GrantFiled: March 12, 2015Date of Patent: September 12, 2017Assignee: AAC ACOUSTIC TECHNOLOGIES (SHENZHEN) CO., LTDInventors: Junjie Yan, Chuandong Wei, Chunhuan Fang, Lei Zhang, Liangwei Wan

Patent number: 9507118Abstract: Disclosed is lens module. The lens module includes a barrel and a lens group disposed in the barrel. The lens group includes a first lens element connecting with the barrel and a second lens element connecting with the first lens element. The first lens element connecting with the barrel makes the lens module have a first matching precision. The first matching precision makes the barrel and the lens group be concentric. The first lens element has a first arc surface and the second lens element has a second arc surface engaging with the first arc surface which makes the lens module have a second matching precision. The second matching precision makes the first lens element and the second lens element be concentric.Type: GrantFiled: March 10, 2015Date of Patent: November 29, 2016Assignee: AAC Acoustic Technologies (Shenzhen) Co. Ltd.Inventors: Junjie Yan, Chuandong Wei, Chunhuan Fang, Lei Zhang, Liangwei Wan
