Technology Field

[0002] As the distribution of various mobile devices has become widespread and wireless internet services have been commercialized, consumer demands related to mobile devices are also diversifying, leading to the installation of various types of accessory devices on mobile devices.

[0003] A representative example among these is the camera module, which captures subjects as photos or videos. Meanwhile, recent camera modules are equipped with optical image stabilization (OIS) features to compensate for user hand shake during shooting. Furthermore, as mobile devices enhance functionality and increase pixel counts, the size of image sensors and lens apertures are also increasing.

[0004] However, as the lens aperture increases, when vibration and shock occur in the camera module, the stress applied to the support member supporting the OIS drive increases, causing deformation and disconnection of the support member, which results in the inability to drive the OIS and oscillation failure.

The second portion (612) of the wire (610) may be coupled to the lower surface of the first substrate (420) by a conductive member.

[0127] In this embodiment, the upper portion of the wire (610) is connected to the first elastic member (510), which is a suspension spring portion, and the lower portion can be connected to a stator (400), such as a base (410), a first substrate (420), or a second coil (430). Although stress may be concentrated in the lower portion of the wire (610) due to falling, impact, or vibration, causing deformation and breakage, in this embodiment, the wire (610) may be provided with a reinforcing structure made of an injection-molded material. Through this, fatigue accumulation caused by the injection-molded material can be relieved. Additionally, the spring constant in the optical axis direction can be increased. Furthermore, as the spring strength increases, the resonance frequency increases, and frequency characteristics can be improved.
