Description

Technical Field

[0001] This embodiment relates to a camera device. Background Technology

[0002] With the widespread adoption of various portable terminals and the commercialization of wireless internet services, consumer demand related to portable terminals has diversified, leading to the installation of various types of add-ons in portable terminals.

[0003] A typical example is a camera module that captures images or videos of a subject. Meanwhile, autofocus, which automatically adjusts the focus based on the distance to the subject, is being applied to more recent camera modules. Furthermore, image stabilization features are used to compensate for user hand shake.

[0004] However, in the prior art, if the portions for soldering the terminals of the lens drive device to the gyroscope sensor are arranged adjacent to each other on the printed circuit board, the soldering work becomes difficult. Therefore, the gyroscope sensor needs to be configured to be spaced apart from the lens actuator, which results in an increase in the size of the printed circuit board. Summary of the Invention

The dummy component 3230 may be disposed on the opposite side of the third magnet 3223 within the housing 3210. The weight of the dummy component 3230 may correspond to the weight of the third magnet 3223. However, the dummy component 3230 may have a lighter weight than the third magnet 3223. Alternatively, the dummy component 3230 may have a heavier weight than the third magnet 3223. The dummy component 3230 may be between 80% and 120% of the weight of the third magnet 3223. If the weight of the dummy component 3230 is less than the lower limit of the above values ​​or exceeds the upper limit of the above values, the weight balance of the OIS drive unit may collapse.

For example, the ratio of the number of turns in the second-third coil 3333 to the number of turns in the second-first coil 3331 and the second-second coil 3332 can be from 1.5:2.0 to 1:1. Ideally, the ratio of the number of turns of the second-third coil 3333 to the number of turns of the second-first coil 3331 and the second-second coil 3332 is 1:1, but due to space constraints, it can be set to 1.5:2.0.

[0361] The second-first magnet 2221 and the second-second magnet 2222 can be quadrupole magnets. A quadrupole magnet may include a neutral portion horizontally disposed in the central portion. Here, the neutral portion may be a gap. The second-first magnet 2221 and the second-second magnet 2222 can be bipolar magnetized.

The fourth coil 2330 may face the second magnet 2220. The fourth coil 2330 may electromagnetically interact with the second magnet 2220. In this case, when current is supplied to the fourth coil 2330 and a magnetic field is formed around the fourth coil 2330, the second magnet 2220 may move against the fourth coil 2330 due to the electromagnetic interaction between the fourth coil 2330 and the second magnet 2220.

Ideally, the ratio of the number of turns of the fourth-third coil 2333 to the number of turns of the fourth-first coil 2331 and the fourth-second coil 2332 is 1:1, but due to space constraints, it can be set to 1.5:2.0.
