Voice coil motor, camera module, and electronic device

A camera module, comprising an image obtaining apparatus and a voice coil, wherein the voice coil motor comprises:

• a support component;
• a transmission component, wherein the transmission component moves relative to the support component;
• and
• a lubrication structure, wherein the lubrication structure is disposed between the support component and the transmission component, the lubrication structure comprises lubricating oil and a plurality of spherical particles dispersed in the lubricating oil, at least a part of the spherical particles have one side in contact with the support component and another side in contact with the transmission component, and when the support component and the transmission component move relative to each other, at least the part of the spherical particles roll relative to the support component and the transmission component, wherein a diameter of the spherical particle is 10 μm to 500 μm;
• wherein the image obtaining apparatus is connected to the transmission component of the voice coil motor;
• the support component of the voice coil motor is provided with a second hole, and the image obtaining apparatus obtains an external image through the second hole;
• one of the support component and the transmission component is provided with the coil, the other of the support component and the transmission component is provided with the third magnetic member, and the coil and the third magnetic member are spaced from each other in a direction parallel to a center line of the second hole;
• and
• under drive of the transmission component, the image obtaining apparatus moves in a direction perpendicular to the center line of the second hole, to compensate for a jitter amount of the camera module.
