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 comprises a voice coil motor, a seat body and a circuit board, wherein the seat body is arranged between the voice coil motor and the circuit board. The voice coil motor comprises a conductive shell. The circuit board comprises a conducting circuit, the conducting circuit comprises a circuit to be shielded, a grounding pad and a closed grounding ring arranged around the circuit tobe shielded and the grounding pad, and the grounding ring is electrically connected with the grounding pad. The seat body comprises a seat body main body and a conductive ring sleeved on the outer side of the seat body, one side of the conductive ring is electrically connected with the conductive shell, and the other side of the conductive ring is electrically connected with the grounding ring; the conductive shell, the conductive ring and the grounding ring jointly form a shielding structure; the shielding structure is used for shielding electromagnetic signals. In addition, the invention also provides an electronic device with the camera module.
