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
The present invention relates to a kind of voice coil motor, particularly relate to a kind of voice coil loudspeaker voice coil being applicable to multiple photographic head being set up in parallel
Motor.
Background technology
Voice coil motor has high frequency sound, high-precision feature.Its cardinal principle is in a permanent-magnetic field, by changing
The DC current size of motor interior loop, controls the stretch position of spring leaf, thus drives up and down motion.Mobile phone camera is wide
General use VCM realizes automatic focusing function, can be regulated the position of camera lens by VCM, presents image clearly.Such as Fig. 1 institute
Showing, voice coil motor includes the parts such as shell 1 ', upper shell fragment 2 ', lower shell fragment 3 ', coil 4 ', Magnet 5 ', lower cover 6 ', and Magnet 5 ' all sets
Put the side at coil 4 '.This traditional voice coil motor, its Magnet 5 ' is made up of four blocks of bar magnets, is arranged in coil
Four limits of 4 ', or as in figure 2 it is shown, Magnet 5 " be made up of four blocks of square Magnet, be arranged in coil 4 " four angles.This
Traditional voice coil motor, when being applied to the camera installation of dual camera, the adjacent Magnet 5 ' on two voice coil motors or magnetic
Ferrum 5 " can interfere, affect the normal work of voice coil motor.
Summary of the invention
It is an object of the invention to provide a kind of sound being applicable to multiple photographic head being set up in parallel that will not interfere
Coil motor.
The present invention is a kind of voice coil motor being applicable to multiple photographic head being set up in parallel, including shell, upper shell fragment, lower bullet
Sheet, coil, Magnet, lower cover；Described lower cover is fixed on the bottom of shell, has one and allow the camera lens pass in the middle part of lower cover
Hole, upper shell fragment and lower shell fragment are all nested with in the enclosure and lay respectively at above and below coil；Outside described Magnet is arranged on
In shell and be positioned at the outside of coil；In described shell and be positioned at the outside of coil and have four accommodation spaces, described Magnet by
Two short Magnet are constituted, and these two short Magnet are separately positioned on the centre position of two accommodation spaces of coil relative side, often
Leaving spacing between the left and right sides and the housing interior side-wall of short Magnet, described another two is not provided with the accommodation space of short Magnet
Outside be the sides adjacent being set up in parallel.
Two described short Magnet are rectangular magnet.
The present invention is a kind of voice coil motor being applicable to multiple photographic head being set up in parallel, in the shell of this voice coil motor and
There are four accommodation spaces in the outside being positioned at coil, and the centre position of the accommodation space that two of which is oppositely arranged is provided with short Magnet,
And leaving spacing between the left and right sides of every short Magnet and housing interior side-wall, it is meant that voice coil motor exists two and does not have magnetic
The sides adjacent of interference, if multiple photographic head is transversely set up in parallel, its sides adjacent being set up in parallel can solve without magnetic disturbance
Multiple side by side and the problem that there is magnetic disturbance between the photographic head that is disposed proximate to.
The present invention is further illustrated with specific embodiment below in conjunction with the accompanying drawings.

Detailed description of the invention
As it is shown on figure 3, the present invention is a kind of voice coil motor being applicable to multiple photographic head being set up in parallel, in embodiment
Being two photographic head being set up in parallel, this voice coil motor includes shell 1, upper shell fragment 2, lower shell fragment 3, coil 4, Magnet 5, lower cover 6.
Described lower cover 6 is fixed on the bottom of shell 1, has a mesopore allowing camera lens pass, upper shell fragment in the middle part of lower cover 6
2 and lower shell fragment 3 be all nested with in shell 1 and lay respectively at above and below coil 4；Described Magnet 5 is arranged in shell 1
And it is positioned at the outside of coil 4.
As shown in Figure 3,4, in described shell 1 and be positioned at the outside of coil 4 and have four accommodation spaces 11,12,13,14,
Described Magnet 5 is made up of two short Magnet 51,52, and these two short Magnet 51,52 are separately positioned on the two of coil 4 relative side
The centre position of individual accommodation space 11,13, leaves spacing between the left and right sides and shell 1 medial wall of two short Magnet 51,52
111,131, the outside of the accommodation space 12,14 that described another two is not provided with Magnet 5 is the sides adjacent being set up in parallel, i.e. ginseng
As shown in Figure 4, two photographic head 10 are transversely set up in parallel, and the Magnet 5 in voice coil motor on two photographic head 10 is positioned at line
The longitudinal direction of circle 4, i.e. coil 4 adjacent surface (outside of accommodation space 12, the 14) non-magnet on two voice coil motors.
The operation principle of the present invention:
In the shell 1 of voice coil motor of the present invention and be positioned at the outside of coil 4 and have four accommodation spaces 11,12,13,14, wherein two
The centre position of the individual accommodation space being oppositely arranged is provided with Magnet 5, and the left and right sides of every short Magnet and shell 1 medial wall it
Between leave spacing 111,131, it is meant that voice coil motor exist two sides adjacent without magnetic disturbance, if multiple photographic head 10
(as shown in Figure 4) being transversely set up in parallel, its sides adjacent being set up in parallel can solve multiple arranged side by side and next-door neighbour without magnetic disturbance
The problem that there is magnetic disturbance between the photographic head arranged.
The emphasis of the present invention is that and uses two Magnet relatively set.
The above, only present pre-ferred embodiments, therefore can not limit, with this, the scope that the present invention implements, i.e. depend on
Equivalence change and the modification that scope of the present invention patent and description are made, all should still belong to the model that patent of the present invention contains
In enclosing.
