Abstract

A mobile terminal includes: a terminal body; and a camera module provided at one side of the terminal body, wherein the camera module includes: a first lens assembly; a second lens assembly provided below the first lens assembly; a diaphragm disposed between the first and second lens assemblies, and having its aperture changed; and an actuator disposed close to the first lens assembly, and configured to reciprocate the first lens assembly, wherein the diaphragm includes: a first blade having a through hole therein; a second blade having a through hole therein, and configured to change an aperture of the diaphragm by a relative motion with respect to the first blade; a link member coupled to end parts of the first and second blades, and configured to move the first and second blades by being rotated; and a motor coupled to one side of the link member, and configured to rotate the link member.

Dependent claims

A mobile terminal, comprising:

a terminal body;
and
a camera module located at one side of the terminal body,
wherein the camera module includes:
a first lens assembly;
a second lens assembly located below the first lens assembly;
a diaphragm located between the first lens assembly and the second lens assembly, and being shaped to have an aperture;
and
an actuator configured to provide reciprocal movement of the first lens assembly relative to the second lens assembly,
wherein the diaphragm includes:
a first blade shaped to define a hole;
a second blade shaped to define a hole and being configured to change the aperture of the diaphragm according to relative motion with respect to the first blade;
a link member coupled to respective end parts of the first blade and the second blade, and configured to move the first blade and the second blade according to rotation of the link member;
and
a motor coupled to one side of the link member and being configured to cause the rotation of the link member,
wherein the actuator includes:
a bobbin shaped to define a region within which the first lens assembly is located;
a housing formed to enclose side surfaces of the bobbin;
one or more magnetic members provided between the bobbin and the housing;
a coil located proximate to the one or more magnetic members, and being configured to generate an electromagnetic force between the coil and the one or more magnetic members;
an upper spring formed on an upper surface of the housing;
a lower spring formed on a lower surface of the housing;
and
a supporting member configured to connect the upper spring with the lower spring.
