Title: CAMERA MODULE AND MOBILE TERMINAL
Abstract:
A camera module and a mobile terminal, the module comprising: a support plate arranged on a substrate; and a shell sealingly connected to the support plate; the lens assembly comprises: an image sensor and a lens; a voice coil drive device comprises: a permanent magnet fixedly connected to the lens and an electromagnet coil surrounding a permanent magnet and fixedly connected to the support plate; the image sensor is arranged between the substrate and the support plate; and the lens is located in a space formed by the shell and a sealing plate, and the shell is filled therein with liquid which provides buoyancy for the lens and the permanent magnet. According to the described technical solution, the electromagnet coil is externally arranged to facilitate heat dissipation, and the buoyancy of liquid is used as part or all of the force to overcome the gravity of the lens and the permanent magnet; when the magnetic force of the electromagnet coil and the permanent magnet is needed to serve as a force to provide part of the force to overcome the gravity no matter where the lens is, energy consumption is thereby reduced and a photographing effect is improved.
