Description

Electronic equipment Technical Field The application relates to the technical field of communication, in particular to electronic equipment. Background With the rapid development of mobile communication technology and the popularization of smart phones, the requirements of electronic devices are increasing, and particularly, the requirements of the communication capability of the electronic devices are increasing. Currently, a common antenna solution of an electronic device with an all-metal architecture is to utilize a non-display area of a display screen to perform an antenna layout, so as to implement a communication function of the electronic device. However, the antenna for signal transmission by using the non-display area of the display screen mainly covers the space on the side of the display screen facing away from the rear cover, so that the signal beam coverage on the side of the rear cover facing away from the display screen of the electronic device is poor. Resulting in poor communication performance of the electronic device. Disclosure of Invention The electronic equipment provided by the application is used for improving the communication performance of the electronic equipment. The application provides an electronic device, which comprises a rear cover, a camera decorating assembly, a first antenna and a floor. The rear cover comprises a mounting hole, the camera decorating assembly comprises a metal decorating plate, and the metal decorating plate is mounted in the mounting hole. In the application, the first antenna comprises the metal decorative plate, and the metal decorative plate comprises a slit and a first feeding point. In addition, the metal decorative plate is arranged at intervals with the floor, and the metal decorative plate and the floor enclose a cavity. That is, in the present application, the first antenna is a cavity antenna. In the electronic equipment provided by the application, the first antenna is arranged by utilizing the partial structure of the camera decoration assembly, so that the integration level of the electronic equipment is improved. In addition, as the signal of the first antenna can be transmitted to the side of the rear cover, which is far away from other parts of the electronic equipment, the signal coverage of the electronic equipment, which is positioned on one side of the rear cover, can be realized, so that the communication requirement between the electronic equipment and the communication equipment on the side is met, and the communication performance of the electronic equipment is improved. In one possible implementation of the application, the floor comprises a circuit board, at least part of the edge of the metal trim panel being connected to a ground plane of the circuit board. Therefore, the metal decorative plate and the circuit board can jointly enclose a cavity of the first antenna, and the structure of the first antenna can be simpler, so that the implementation difficulty of the scheme is reduced. And because the edge of the metal decorative plate is connected with the grounding layer of the circuit board, the cavity enclosed by the metal decorative plate and the circuit board is larger, so that the signal transmission performance of the first antenna is improved. The connection mode of the metal decorative plate and the grounding layer of the circuit board is not limited, for example, in one possible implementation mode, at least part of the edge of the metal decorative plate is connected with the grounding layer of the circuit board through a conductive connecting piece, and the conductive connecting piece comprises at least one of conductive foam or metal shrapnel. The connection reliability of the metal decorative plate and the grounding layer of the circuit board is improved, so that the boundary integrity of the cavity of the first antenna is improved, and the signal transmission performance of the first antenna is improved. In one possible implementation of the application, the projection of the circuit board onto the rear cover covers the mounting hole. Thus, the cavity of the first antenna is increased, and the signal transmission performance of the first antenna is improved. In one possible implementation of the present application, the metal decorative board includes a first metal pillar, the first metal pillar is disposed on a surface of the metal decorative board facing the circuit board, and the first metal pillar serves as the first feeding point. This may facilitate the connection of the first feed point to the radio frequency circuitry of the first antenna. In another possible implementation of the present application, the metal decorative board may further include a second metal post, where the second metal post is disposed on a surface of the metal decorative board facing the circuit board. In addition, the first antenna further comprises a tuning circuit, and the tuning circuit is connected with the second metal post a
