Specific embodiment
As Figure 1-Figure 4, the present invention is a kind of dual camera voice coil motor, including housing 1, support 2, coil 3, Magnet
4th, lower cover 5.
Described lower cover 5 is fixed on the bottom of housing 1, coil 3 on support 2, Magnet 4 in housing 1 and
It is located at the outside of coil 3.
In the present embodiment, described coil 3 has two kinds installed in the mode of support 2：
The first mounting means is：Described coil 3 is runway coil 3, is respectively equipped with three in the left side wall and right side wall of support 2
Individual projection 21, on 2 two relative side walls of support（That is, left side wall and right side wall）Runway coil 3 is separately installed with, which is installed
Mode is projection 21 peripheral coiling of the described coil 3 along support 2, is wrapped in support so as to form runway coil, i.e. coil 3
2 projection 21.Two containing cavities 11 being arranged side by side are provided with described housing 1, two supports 2 for being provided with coil 3 are side by side
In two containing cavities 11 of housing 1.Described Magnet 4 has three pieces, and three blocks of Magnet 4 are separately mounted to two supports 2
Outside and two supports 2 between, Magnet 4 between two supports 2 is for sharing Magnet.
If it should be noted that coil is the coil for etching, coil directly can be fitted on the outer wall of support.
Described Magnet 4 can be conventional Magnet, or bipolar magnet 4.
With reference to shown in Fig. 5, for bipolar magnet 4, bipolar magnet 4 between two supports 3 in its three pieces of bipolar magnets 4, is located at
Magnetic pole with installed in two 3 outside bipolar magnet of support, 4 opposite faces magnetic pole identical, i.e. three pieces of bipolar magnets 4 from a left side to
The right side, it is N/S that the upper magnetic pole of first piece of bipolar magnet 41 is S/N, lower magnet, and the upper magnetic pole of second piece of bipolar magnet 42 is
N/S, lower magnet are S/N, and it is N/S that the upper magnetic pole of the 3rd piece of bipolar magnet 43 is S/N, lower magnet.It should be noted that：
4 magnetic pole of bipolar magnet also can be conversely, but must positioned at the direction of 2 both sides Magnet 4 of support and the active force of the interaction generation of coil 3
Must be consistent.That is the coil of support both sides must be subject to power up or down simultaneously.
Described bipolar magnet 4 refers to that upper magnetic pole and the middle setting of lower magnet have NULL 44, be one into
Type is out；And can also be wrapped up in one NULL 44 of middle setting again with two panels conventional magnet.The NULL 44
Cross central line just to runway coil 3（As shown in Figure 3）.
Second mounting means be（Do not regard in figure）：Described coil 3 is wrapped on the outer wall of support 2.Described Magnet 4
There are three pieces, three blocks of Magnet are separately mounted between the outside of two supports 2 and two supports 2.
As Figure 6-Figure 8, for described coil 3 is wrapped in the structure on the outer wall of support 2, three blocks of Magnet 4 '
In be located at two supports 2 ' between Magnet 4 ' magnetic pole be arranged on two 2 ' outer magnet of support, 4 ' opposite faces magnetic pole phase
With, i.e. from left to right, the magnetic pole of first block of Magnet 41 ' is S/N to three blocks of Magnet 4 ', and the magnetic pole of second block of Magnet 42 ' is N/S, the
The magnetic pole of three blocks of Magnet 43 ' is S/N（As shown in Figure 9）.Ensure to be located at 2 ' both sides Magnet 4 ' of single support and 3 ' phase interaction of coil
Must be consistent with the direction of the active force for producing.
It should be noted that the start part of voice coil motor can be spring-piece type, or ball-type.
