It should be noted that the conductive frame 220 is an annular frame, and a hollow area is formed in the annular frame, and the hollow area is also used for placing other devices, such as a power module, a camera module, and the like.

It should be noted that the conductive unit 221A may directly obtain an antenna electrical signal from a feeding end (not shown) on the motherboard (that is, the feeding end directly feeds the antenna electrical signal into the conductive unit 221A), and couple and feed the antenna electrical signal to the first radiator 221B through the slot G, so that resonance is generated between the conductive unit 221A and the first radiator 221B, and the resonant frequency may be adjusted by adjusting the antenna electrical signal fed from the feeding end, so that the conductive unit 221A and the first radiator 221B radiate a preset frequency band signal.

It should be understood that, referring to fig. 2, a plurality of gaps G are further disposed between the conductive bezel 220 and the middle plate 210, and the gaps G may include two portions, one of which is an opening P formed through the conductive bezel 220 in a direction from the middle plate 210 to the conductive bezel 220; the second is a parasitic portion Q communicating with the opening P.

Although the touch panel 731 and the display panel 741 are two independent components in fig. 7 to implement the input and output functions of the mobile phone, in some embodiments, the touch panel 731 and the display panel 741 may be integrated to implement the input and output functions of the mobile phone.

WIFI belongs to short-distance wireless transmission technology, and the mobile phone can help a user to receive and send electronic mails, browse webpages, access streaming media and the like through the WIFI module 770, and provides wireless broadband internet access for the user. Although fig. 7 illustrates the WIFI module 770, it can be understood that the antenna assembly includes a radiation segment of the WIFI frequency band, that is, the fourth radiator 223 or the first parasitic radiator 226 or the second parasitic radiator 227, and the radiators can implement signal transceiving of the WIFI frequency band, so the WIFI module 770 does not belong to an essential component of the mobile phone 700 and can be omitted as needed.

The processor 780 is a control center of the mobile phone, connects various parts of the entire mobile phone by using various interfaces and lines, and performs various functions of the mobile phone and processes data by operating or executing software programs and/or modules stored in the memory 720 and calling data stored in the memory 720, thereby integrally monitoring the mobile phone.
