Embodiment Construction
[0017] In order to facilitate the understanding of those skilled in the art, the structural principle of the present invention will be further described in detail below in conjunction with specific embodiments and accompanying drawings:
[0018] Such as figure 1 Shown is the connection diagram of the application structure of the device of the present invention on the mobile phone. On the circuit board PCB 1 of the mobile phone, a mobile phone antenna 2, an audio component 3, an audio circuit module 4, and other circuit modules 5 are arranged. Inductors 6-1 and 6-2 are respectively connected in series on the pins 3-1 and 3-2, and the inductors 6-1 and 6-2 are connected to the pins 4-1 and 4-2 of the audio circuit module. The resistance values of -1 and 6-2 are between 40 and 120nH, and the surroundings of the inductors 6-1 and 6-2 and the upper and lower copper clad grounds are cleaned, and the clearance area is 1 to 3mm around the inductors. If there is no clearance treatme...
