Description

Electronic equipment Technical Field The application relates to the technical field of electronic products, in particular to electronic equipment. Background In the related art, some electronic devices generally include an antenna in the form of a coil, for example, a Near Field Communication (NFC) antenna, and the coil of the antenna is generally disposed close to one or more camera assemblies in order to improve space utilization of the electronic device. Therefore, under the scene that the camera and the antenna coil work simultaneously, the radiation energy of the antenna coil can interfere the camera module, so that the problem of stripes in the shot photo is solved, and the shooting experience is affected. Therefore, in the related art, in a scenario that the camera and the antenna coil work simultaneously, there is a problem that radiation energy of the antenna coil can interfere with the camera module. Disclosure of Invention The embodiment of the application provides electronic equipment, which can solve the problem that in the related art, under the scene that a camera and an antenna coil work simultaneously, the radiation energy of the antenna coil can interfere with a camera module. In a first aspect, an electronic device is provided, comprising an antenna assembly and a camera module, wherein the antenna assembly comprises a first coil and a second coil, the first coil is arranged around the camera module, and the camera module is positioned outside the second coil; The camera module is in an open state, current in the first coil is first current, the camera module is in a closed state, current in the first coil is second current, the first current is smaller than the second current, and the second coil is in a working state when the camera module is in the open state. In the embodiment of the application, the first coil is arranged around the camera module, so that the current in the first coil is a first current when the camera module is in an open state, the current in the first coil is a second current when the camera module is in a closed state, and the first current is smaller than the second current, namely, when the camera module is in the closed state, the current in the first coil arranged around the camera module is reduced, and accordingly, the magnetic flux in the first coil is also reduced. Therefore, in the scene that the camera module and the antenna assembly work simultaneously, the magnetic flux in the first coil is reduced, so that the interference degree of the first coil on the camera module inside the camera module can be reduced. Meanwhile, as the camera module is in the open state and the second coil is in the working state, under the scene that the camera module and the antenna assembly work simultaneously, the antenna assembly can communicate based on the first coil and the second coil or one of the two at the same time, so that the antenna assembly has better antenna performance under the state, and as the second coil is positioned outside the camera module and does not surround the camera module, the interference degree to the camera module in the working process of the second coil is smaller. Therefore, the electronic equipment provided by the application can ensure that the antenna assembly has better antenna performance and simultaneously reduces the interference degree of the antenna assembly on the camera module inside the electronic equipment under the scene that the camera module and the antenna assembly work simultaneously.
