Problems solved by technology

[0003] Among them, the scheme of using the rod-type FM antenna will affect the aesthetics and convenience of use of the mobile phone, and the reliability of the rod-type FM antenna is poor and the cost is high, so this structure has been gradually eliminated; the use of earphone wires as the FM antenna The solution needs to insert earphones when listening to the radio, which affects the normal use and convenience of the mobile phone, and when the earphone cable is used as the FM antenna, multiple people are not allowed to listen to the FM radio on one electronic device at the same time, so the earphone cable is used as the built-in FM antenna Broadcast applications have caused restrictions; the solution of using an independent built-in FM antenna, due to the size and headroom limitations of electronic equipment, requires the addition of high-cost built-in antenna components, and the number of channels searched and broadcast performance are poor
[0004] Moreover, with the development of science and technology, the structural design of electronic equipment is becoming more and more refined and complex, and the antenna clearance area required for setting FM broadcasting functions on electronic equipment is limited, and the realization of fully built-in FM antennas has fallen into a bottleneck

example 1

[0039] Example 1: If Figure 9 As shown, the structural component 11 can be the rear camera component 11a of the mobile phone, and the structure and size of the rear camera component 11a are designed according to the hardware structural conditions of the mobile phone and the requirements of the FM broadcasting circuit 2 . The rear camera assembly 11a in this embodiment includes a camera 11a-1 and a camera structural member 11a-2, wherein the camera structural member 11a-2 is formed with a mounting hole matching the camera 11a-1 to facilitate the installation of the camera 11a-1 The limit is fixed; the camera structure 11a-2 here is made of all-metal material to form the FM antenna, and one end of the conductive connector 4 is connected to the camera structure 11a-2 of the rear camera assembly 11A, and the other end is connected to the main board 3 ( Figure 9 (not shown in ) and is connected to the connecting shrapnel 21 of the FM radio circuit 2. Here, the conductive connect...

[0040] Example 2: If Figure 10 As shown, the structural component 11 can be the rear camera component 11a of the mobile phone, and the difference from Example 1 is that Figure 10 The camera structural member 11a-2 in the shown rear camera assembly 11a includes a structural member body A of insulating material and a metal ring A1 (the shaded area shown in Figure 10 ) embedded in the structural member body A. The metal ring A1 Arranged around the camera 11a-1, the metal ring A1 can form an FM antenna and be connected to the connection shrapnel 21 of the FM radio circuit 2 through the conductive connecting body 4; in addition, as Figure 10 The metal ring A1 shown is a certain distance away from the edge of the camera structure 11a-2. Therefore, compared with the structure of Example 1, the conductive connecting body 4 is extended a part toward the rear camera assembly 11a to couple with the metal ring A1. Of course, the metal ring A1 here can also be formed on the camera body...

example 3

[0041] Example 3: If Figure 11 As shown, the structural component 11 may be an earpiece dust-proof net component 11d of a mobile phone, and the earpiece dust-proof net component 11d may be made of all-metal material to form an FM antenna. Conductive connecting body 4 selects metal screw for use, and the afterbody of metal screw passes earpiece dust-proof net assembly 11d to main board 3 ( Figure 11 (not shown in ) extends to connect with the connection elastic piece 21 of the FM broadcasting circuit 2. It should be understood that for other structural introductions and broadcast signal receiving processing procedures in this example, reference may be made to the specific description of the above-mentioned example 1, and details are not repeated here.

Description

technical field [0001] The present application relates to the technical field of terminals, and in particular to an electronic device. Background technique [0002] The frequency modulation (FM) broadcasting (frequency modulation, FM) function of traditional electronic devices (such as mobile phones, tablet computers, etc.) generally uses a rod antenna, or uses an earphone cable as an FM broadcasting antenna, or uses an independent built-in FM broadcasting antenna (such as a dedicated flexible Line antenna or antenna device made of magnetic core copper wire) to achieve. [0003] Among them, the scheme of using the rod-type FM antenna will affect the aesthetics and convenience of use of the mobile phone, and the reliability of the rod-type FM antenna is poor and the cost is high, so this structure has been gradually eliminated; the use of earphone wires as the FM antenna The solution needs to insert earphones when listening to the radio, which affects the normal use and conv...
