Abstract
A dual drive system (1) has a drive shaft (A) and comprises a first magnet (2), a second magnet (3), a first coil (4) and a second coil (5). The first magnet (2), the second magnet (3), the first coil (4) and the second coil (5) are arranged in an at least partially overlapping manner in a direction perpendicular to the drive shaft (A). Operating the current in the first coil (4) generates a first movement (M1) along the drive shaft (a), operating the current in the second coil (5) generates a second movement (M2) along the drive shaft (a). The first movement (M1) and the second movement (M2) are independent of each other. By arranging the coils and the magnets of the dual drive system one above the other, a very compact solution is provided, which is advantageous for the appearance of the opto-mechanical system and the electronic device in which it is to be arranged.
Description
Technical Field
The invention relates to a dual drive system having a drive shaft, the drive system including magnets and coils.
Background
There are several difficulties with opto-mechanical systems for portable electronic devices. Preferably, electronic devices such as cell phones have as small an external size as possible, while opto-mechanical systems need to be sized to provide sufficient image clarity, spatial frequency, sensitivity, etc.
Conventional optical zoom cameras typically include two moving lens groups, one for focusing and one for zooming, which utilize separate actuators, such as voice coil actuators. The two drivers are separate units that occupy a certain volume and affect the appearance of the camera module. In particular, the opto-mechanical system comprising a deformable lens requiring mechanical deformation takes up a large space, since a high deformation force of several hundred millinewtons is required. The force generation efficiency of most common voice coil drivers is still relatively low with respect to power consumption, so the size of the magnet and coil must be a few millimeters.
Accordingly, the imaging zoom of portable electronic devices is mostly a digital zoom, which unfortunately affects the resolution of images taken using a camera. Digital zooming does not add any information to the image, but merely crops and scales a portion of the original image to a larger size. Optical zooming, on the other hand, uses lenses to magnify an object and provide more detail at the original resolution, thereby providing a higher resolution image.
