Problems solved by technology
[0002] In the prior art, in order to solve the problem of electromagnetic interference of the mobile phone camera module, a metal shielding shell is added outside the camera module, and then the metal shielding shell is welded on the circuit board. However, in order to avoid short circuit, the lead of the metal shielding shell The feet need to avoid the soldering position of the circuit board, so that the camera module cannot be completely surrounded by the metal shielding shell, resulting in the inability to form effective electromagnetic shielding; at the same time, adding a metal shielding shell will increase the number of components of the mobile phone camera module, which increases the complexity of production and manufacturing costs; moreover, the addition of a metal shielding case design will lead to an increase in the size of the mobile phone camera module, which is not in line with the development trend of thin and light mobile phones and high screen-to-body ratio

A camera module includes a voice coil motor, a seat body and a circuit board, and the seat body is arranged between the voice coil motor and the circuit board. The voice coil motor includes a conductive housing. The circuit board includes a conductive line, the conductive line includes a line to be shielded, a grounding pad, and a closed grounding ring arranged around the line to be shielded and the grounding pad, and the grounding ring is electrically connected to the grounding pad . The base body includes a base body and a conductive ring sleeved on the outside of the base body, and one side of the conductive ring is electrically connected to the conductive housing, and the other side is electrically connected to the grounding ring. Sexual connection, wherein, the conductive housing, the conductive ring and the grounding ring jointly form a shielding structure, and the shielding structure is used for shielding electromagnetic signals. In addition, the invention also provides an electronic device with the camera module.
