Zusammenfassung: | A simplified zoom lens module includes first to third lens units, first and second driving assemblies, and a housing. The lens units are arranged along an optical axis. The first driving assembly moves the second lens unit back and forth relative to the first lens unit, the second driving assembly moves the third lens unit back and forth relative to the second lens unit. The first driving assembly includes a first magnet which interacts with a second magnet, one being a permanent magnet, the other being an electromagnet. The first magnet is fixed inside the housing, the second magnet is fixed on the second lens unit. The first and second magnets are attracted to or repelled from each other by voltage and current fed to the electromagnet, thereby moving the lens and changing the focus of the lens module. A module and image-capturing device are also disclosed. |
