Embodiment 1
[0021] Embodiment 1 of the present invention discloses a camera module. The camera module includes: a lens, a voice coil motor, a base, a filter, a circuit board and an image sensor. The lens is mounted on the voice coil motor.
[0022] Wherein, the base has an opposite first surface, a second surface and an inner cavity passing through the first surface and the second surface, the voice coil motor is installed on the first surface, and the second surface of the base is installed on the circuit board;
[0023] The image sensor is built into the inner cavity of the base, and is coaxially installed on the circuit board with the lens, and the optical filter is attached to the upper surface of the image sensor. The area of the light sheet.
[0024] In practical applications, when the camera module focuses, the lens can pass through the inner cavity of the base and approach the image sensor driven by the voice coil motor, so as to form a clear image surface on the image sensor. ...
Embodiment 2
[0037] Referring to the first embodiment, the second embodiment is based on the first embodiment, a circuit board is provided with an accommodating cavity, and the image sensor is fixed in the accommodating cavity.
[0038] More preferably, the image sensor can be fixed in the housing cavity by insulating glue. After the image sensor is fixed in the housing cavity, it can be soldered with gold wires and preset solder pins on the circuit board to form an electrical connection. The depth of the housing cavity can be set to After the image sensor is fixed, the upper surface of the image sensor is in the same plane as the upper surface of the circuit board.
[0039] In order to enable those skilled in the art to better understand Embodiment 2 of the present invention, the following is illustrated by specific examples:
[0040] Such as image 3 Shown is a schematic structural diagram of a camera module according to Embodiment 2 of the present invention. The camera module includes:...
Embodiment 3
[0049] Embodiment 3 of the present invention discloses a mobile terminal. The mobile terminal includes a camera module. The camera module includes: a lens, a voice coil motor, a base, an optical filter, a circuit board, and an image sensor. The lens is installed In the voice coil motor, wherein,
[0050] The base has an opposite first surface, a second surface, and an inner cavity passing through the first surface and the second surface, the voice coil motor is installed on the first surface, and the second surface of the base mounted on the circuit board;
[0051] The image sensor is built into the inner cavity of the base, and is coaxially installed on the circuit board with the lens, the optical filter is attached to the upper surface of the image sensor, and the inner cavity of the base The minimum cross-sectional area in the direction perpendicular to the axis of the lens is larger than the area of the optical filter.
[0052] Preferably, the lens approaches the image...
