Background
With the development of science and technology, wearable equipment such as all kinds of mobile devices such as panel computer, cell-phone or intelligent wrist-watch all can install miniature camera. When using above-mentioned equipment to shoot at the staff, because the rocking of hand causes the shake for the picture of shooing is fuzzy, and the current reason that causes the picture to be fuzzy of shooing mainly has two aspects: (1) the object moves relative to the lens, causing a change in the imaging; (2) The deflection of the lens axis relative to the initial position of the lens axis causes a change in the image.
In order to solve the above problems, an anti-shake camera device is generally adopted, in which an OIS (Optical Image Stabilization) detects a minute movement through a gyroscope in a lens, then transmits a signal to a microprocessor, the microprocessor immediately calculates a displacement amount to be compensated, and then compensates the displacement amount according to a shake direction of the lens through a compensation lens group, thereby effectively overcoming an Image blur caused by vibration. However, moving-magnet four-side magnets or four-corner magnets are mostly adopted in the conventional OIS optical anti-shake system, and the moving-magnet four-side magnets or four-corner magnets are difficult to resist external magnetic field interference, so that the magnets on one side are interfered by the magnetic field to cause lens offset, and the optical axis of the lens deflects relative to the initial position of the optical axis of the lens to cause imaging change, so that the imaged picture is easy to be unclear. Further, the system in which the magnets are provided on four sides or four corners leads to a large weight and size of the lens moving part, and requires a high level of suspension spring, and further miniaturization of the driving device is difficult.

In this embodiment, two focusing coils 42 are included, both of which are wound around the X-axis direction and fixed on two opposite outer sidewalls of the lens holder 31 in the X-axis direction. The focusing coil 42 is wound in an oblong shape having two long sides substantially parallel to the Y-axis direction and two short sides substantially parallel to the Z-axis direction, and the short sides should be as short as possible for better driving effect. The first magnet assemblies 43 are fixed to the inside of the magnet holder 32, and are provided in one-to-one correspondence with the focusing coils 42 in the X-axis direction. In this embodiment, two sets of first magnet assemblies 43 are included, and are respectively disposed opposite to the two focusing coils 42. Each set of the first magnet assemblies 43 includes two dipole magnets arranged back and forth in the optical axis direction, each magnet being opposed to one long side of the focusing coil 42, and the two magnetic poles of the magnets being arranged back and forth in the X axis direction, respectively.

The second anti-shake coil 54 is fixed on the circuit board 11 and can be directly electrically connected to the circuit board 11.
In operation, when the focusing coil 42 is energized, the lens holder moves along the optical axis direction under the lorentn magnetic force in the optical axis direction in the magnetic field generated by the first magnet assembly 43, thereby achieving the focusing function. When the shake is detected, the circuit board 11 supplies power to the first anti-shake coil 52, the second anti-shake coil 54, or both the first and second anti-shake coils 52 and 54, so that the anti-shake coil in the magnetic field is subjected to the lorentz force in the X-axis direction or the Y-axis direction or the combined direction of the X-axis direction and the Y-axis direction, and the lens holder is controlled to move in the direction perpendicular to the optical axis to counteract the influence of the shake, thereby realizing the optical anti-shake function.

Fig. 2 (c) shows the positional relationship of the position detection element 6 and the second magnet assembly 53 in the optical axis direction when the anti-shake actuator 5 drives the lens to move in the Y-axis direction. The position detecting element 6 is used for detecting the magnetic field change, and the calculating unit on the circuit board can obtain the specific position of the magnet support 32 in the direction perpendicular to the optical axis according to the detected magnetic field change to form closed-loop control.

Compared with four groups of magnets and one focusing coil arranged on four sides or four corners in the prior art, the movable part supported by the second spring assembly 51 is lighter, so that the movement inertia is reduced, the strength requirement on the second spring assembly 51 is reduced, the reaction is more sensitive during OIS driving, the control is easier, and the structure is more compact. In addition, the magnet is arranged on the magnet support only in the X-axis direction, so that when a magnetic field exists on the outer side of the lens driving device in the Y-axis direction, the interference on the operation of the lens driving device is not easy to generate, and the device can normally operate. And also conveniently form the double cameras.
In this embodiment, the second anti-shake coil 54 is an independent wound coil fixed on the front side of the circuit board 11, and in other embodiments, the second anti-shake coil 54 may be a flat coil formed on the circuit board by etching or the like. In this embodiment, the focusing coil 42 is two coils fixed on two opposite outer sides of the lens holder, and in other embodiments, two or more coils may be disposed on each side, so that there are four or more focusing coils. The corresponding first magnet assembly can be split into a plurality of magnets. Similarly, each first anti-shake coil 52 may also be replaced by two or more coils arranged side by side. The second magnet assembly may also be secured directly to the base. Each set of second magnet assemblies may also include three or more magnets arranged side-by-side with a gap formed between adjacent magnets. Further, hall elements may be provided in both the X-axis direction and the Y-axis direction, so that there are two hall elements for detecting the movement positions of the mirror base in the X-axis direction and the Y-axis direction, respectively.
In other embodiments, only one set of focusing coils and one set of first magnet assemblies may be provided, i.e. only one set of focusing coils and first magnet assemblies is provided on one side of the lens holder in the X-axis direction and the other side is not provided. So that the other pair of focus actuators of the other lens driving device can be operated together when the two cameras are combined.
