摘要： This application discloses a linkage apparatus, a camera module, and an electronic device. The linkage apparatus is used in the camera module with continuous zooming, and includes a base, and a first carrier and a second carrier that are slidably connected to the base. A first positioning element is disposed on the base, a first sensing element and a second positioning element are disposed on the first carrier, and a second sensing element is disposed on the second carrier. The first sensing element is disposed opposite to the first positioning element, to detect a location of the first carrier relative to the base. The second sensing element is disposed opposite to the second positioning element, to detect a location of the second carrier relative to the first carrier. A movement relationship between the first carrier and the second carrier is set as an associated movement.
