Description

TECHNICAL FIELD This application relates to the field of electronic devices, and in particular, to a camera apparatus and an electronic device. BACKGROUND With the development of science and technology, anti-shaking demand for camera apparatuses is increasing. One of existing anti-shaking technologies is implemented based on motion of a chip. Compared with an anti-shaking technology that is implemented based on motion of a lens, this anti-shaking technology has the following advantages: Because the chip is smaller and lighter, power consumed in driving the chip to move for shake prevention is less, and an entire anti-shaking mechanism can be designed smaller. Therefore, the chip motion-based anti-shaking technology is widely applied to camera apparatuses, helping the camera apparatuses implement shake prevention during shooting, and further enabling the camera apparatuses to develop toward weight reduction and lower power consumption. However, in a currently used chip-based anti-shaking technology, a hardware structure usually uses a flexible printed circuit (FPC) for connection and conduction of a chip. Because the flexible printed circuit occupies large space due to its own structural feature, an entire chip-based anti-shaking mechanism cannot be further minified. This prevents a camera apparatus provided with the chip-based anti-shaking mechanism from further developing toward weight reduction and miniaturization. US 2020036898A1 discloses an image sensor driving mechanism. US 20190141248A1 discloses optical image stabilization with voice coil motor for moving image sensor. CN 111683454A discloses a circuit board structure of a miniature anti-shake holder. SUMMARY This application provides a camera apparatus and an electronic device, as defined in the appended set of claims, to resolve a problem that an anti-shaking mechanism of a camera apparatus occupies large space. Beneficial effects of this application are as follows: In the camera apparatus of this application, an anti-shaking driving mechanism includes a substrate, an anti-shaking elastic member, and a base. The substrate is movably connected to the base through the anti-shaking elastic member. A photosensitive chip and a second driving member are disposed on the substrate, so that when a first driving member drives the second driving member, the photosensitive chip is enabled to follow the substrate, thereby achieving the purpose of shake prevention. According to the design of this application, the size of the anti-shaking driving mechanism can be reduced, so that the overall size of the camera apparatus is reduced, an integration level is improved, and an electronic device provided with the camera apparatus is enabled to further develop toward weight reduction and miniaturization.
