Problems solved by technology

[0002] Mobile phones generally use speaker components and PCB (Printed Circuit Board, printed circuit board) boards with RF matching circuits distributed on the left and right at the bottom of the mobile phone, such as figure 1 As shown, the speaker assembly 104 and the PCB board 105 are distributed left and right, the power supply 103 supplies power to other devices through the motherboard 102, the PCB board 105 obtains power from the motherboard 102 through the FPC ((Flexible Printed Circuit, flexible circuit board) 106, and the speaker assembly 104 passes through the FPC108 Power is obtained from the PCB board 105, and the RF matching circuit on the PCB board 105 is connected to the lower frame 1015 or the side frame 1013 of the metal frame 101 to realize the antenna function, but as the screen ratio of the display screen of the mobile phone increases, the antenna clearance Smaller and smaller, it is difficult to meet the antenna performance
