Embodiment Construction

[0012] Such as image 3 As shown, the present invention is a voice coil motor suitable for a plurality of cameras arranged in parallel, which is two cameras arranged in parallel in the embodiment. The voice coil motor includes a casing 1, an upper elastic piece 2, a lower elastic piece 3, and a coil 4. Magnet 5, lower cover 6.

[0013] The lower cover 6 is fixed on the bottom of the housing 1, and the middle part of the lower cover 6 has a middle hole through which the lens passes. Both the upper elastic piece 2 and the lower elastic piece 3 are nested in the outer casing 1 and are located above and below the coil 4 respectively. ; The magnet 5 is installed in the shell 1 and located outside the coil 4 .

[0014] Such as image 3 , 4 As shown, there are four accommodating spaces 11, 12, 13, 14 inside the housing 1 and outside the coil 4, the magnet 5 is composed of two short magnets 51, 52, the two short magnets 51 , 52 are respectively arranged in the middle of the two ac...

Abstract

The invention relates to a voice coil motor suitable for multiple cameras in parallel arrangement, including a shell, an upper spring, a lower spring, a coil, a magnet and a lower cover. The magnet is arranged inside the shell and at the outer side of the coil. Also in the shell and at the outer side of the coil, there are four holding spaces. The magnet is composed of two short magnets, which are placed at the central positions of two holding spaces respectively relative to the side edge of the coil; gaps are reserved between the left side of each short magnet and the inner wall of the shell as well as between the right side of each short magnet and the inner wall of the shell. The outer sides of the other two holding spaces without short magnets are adjacent sides in parallel arrangement, which means that the voice coil motor has two adjacent sides that are free of electromagnetic interference. If a plurality of cameras is laterally arranged in parallel, their adjacent sides in parallel arrangement are free of electromagnetic interference, thus addressing the problem that electromagnetic interference exists between two closely adjacent cameras among a plurality of camera in parallel arrangement.

Description

technical field [0001] The invention relates to a voice coil motor, in particular to a voice coil motor suitable for a plurality of parallel cameras. Background technique [0002] The voice coil motor has the characteristics of high frequency response and high precision. Its main principle is to control the stretching position of the spring leaf by changing the DC current of the inner coil of the motor in a permanent magnetic field, thereby driving the up and down movement. Mobile phone cameras widely use VCM to realize the auto-focus function, through which the position of the lens can be adjusted to present a clear image. Such as figure 1 As shown, the voice coil motor includes a casing 1', an upper elastic piece 2', a lower elastic piece 3', a coil 4', a magnet 5', a lower cover 6' and other components, and the magnet 5' is all arranged on one side of the coil 4'. In this traditional voice coil motor, its magnet 5' consists of four bar magnets, which are respectively a...
