Above-mentioned camera module 100, the second magnetic assembly 173 can generate magnetic field when being powered, and magnetic fields are in the second mangneto
It can drive the second magnetostrictive film 171 flexible when Flexible film 171 and drive lens unit 121 moves in a second direction, when taking the photograph
When generating shake in shooting process as head mould group 100, mobile lens unit 121 can be in second direction to camera module
100 are compensated by, and to reduce influence of the shake to shooting, and then can promote the quality of shooting.Due to using magnetostrictive film
As actuator, magnetostrictive film can produce relatively large displacement under relatively small magnetic fields, magnetic field strength
Increasing can be realized by increasing electric current, therefore the second regulating mechanism 170 can provide relatively large driving force to meet
The stabilization requirement of high-pixel camera mould group 100, and be conducive to the Miniaturization Design of camera module 100.It is generated using coil
Magnetic field, and by magnetic fields in the second magnetostrictive film 171, the structure of the second regulating mechanism 170 of this structure is more simple
It is single, be conducive to miniaturization, the lightening design of camera module 100, and relatively high control precision can be obtained.First adjusts
It saves mechanism 130 and the second regulating mechanism 170 and combines setting, camera module 100 may be implemented in a first direction and second direction
Stabilization, be conducive to promote the quality that camera module 100 is shot, and the miniaturization for being advantageously implemented camera module 100 is set
Meter.
Each technical characteristic of embodiment described above can be combined arbitrarily, for simplicity of description, not to above-mentioned reality
It applies all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, all should be considered as described in this specification.
The several embodiments of the application above described embodiment only expresses, the description thereof is more specific and detailed, but simultaneously
The limitation to claim therefore cannot be interpreted as.It should be pointed out that coming for those of ordinary skill in the art
It says, without departing from the concept of this application, various modifications and improvements can be made, these belong to the protection of the application
Range.Therefore, the scope of protection shall be subject to the appended claims for the application patent.
