Low-thickness voice coil motor for camera

The utility model discloses a low-thickness voice coil motor for a camera. The electromagnetic relay comprises an upper shell, a lower shell, an upper elastic sheet, a lower elastic sheet, a carrier,a coil, a positioning rod, a positioning block, a magnet, a magnetism blocking sheet and a conductive terminal, two conductive ends are arranged on the lower shell; a lower elastic sheet is arranged on the lower shell; a coil is arranged above the lower elastic sheet; the coil is wound on the outer side of the carrier; an upper elastic sheet is arranged above the carrier; a gasket is arranged above the upper elastic piece, an upper shell is arranged above the gasket, the upper shell and the lower shell form a magnet yoke, magnets are arranged on the four sides of the upper shell, magnetism blocking pieces are arranged on the upper shell and the lower shell respectively, the positioning rod is arranged on the lower shell, and the positioning blocks are arranged on the four sides of the coil. The structure is ultrathin, magnetic flux leakage can be effectively prevented, the magnetic field intensity of the magnet yoke can be maintained, coil short circuit can be prevented, and practicality is high. 本实用新型公开了一种摄像头用低厚度的音圈电机，包括上壳体、下壳体、上弹片、下弹片、载体、线圈、定位杆、定位块、磁石、阻磁片和导电端子，所述下壳体上设置有两个导电端，所述下壳体上设置有下弹片，所述下弹片上方设置有线圈，所述线圈绕装在载体外侧，所述载体上方设置有上弹片，所述上弹片上方设置有垫圈，所述垫圈上方设置有上壳体，所述上壳体和下壳体组成磁轭，所述上壳体四侧设置有磁石，所述上壳体和下壳体上均设置有阻磁片，所述定位杆设置在下壳体上，所述定位块设置在线圈四侧。本实用新型结构超薄且能够有效防止漏磁，维持磁轭的磁场强度，同时能够防止线圈短路，实用性强。
