[0018] The electronic device 100 includes a frame 101, a first metal strip 102, and a second metal strip 103.

[0019] The frame 101 can be a rounded rectangular frame 101. The rounded rectangular frame 101 includes a bottom 1011, a first side 1012, a top 1013, and a second side 1014 connected in sequence, and the first side 1012 and the second side 1014 are oppositely arranged. The material of the frame 101 can be an insulating material, for example, the frame 101 is made of plastic, resin, or the like.

[0020] The first metal strip 102 and the second metal strip 103 can jointly form an FM antenna radiator. The first metal strip 102 and the second metal strip 103 can be integrated on the frame 101, and the frame 101 provides insulation protection for the first metal strip 102 and the second metal strip 103.

[0021] The first metal strip 102 is arranged along the first side 1012 and extends to the bottom 1011, and the second metal strip 103 is arranged along the second side 1014 and extends to the bottom 1011. The second metal strip 103 is arranged in a spaced manner with the first metal strip 102, and the first metal strip 102 and the second metal strip 103 are connected in series.

[0022] The first metal strip 102 and the second metal strip 103 jointly form an antenna radiator, and a free end of the second metal strip 103 forms a terminal end of the FM antenna radiator. The first metal strip 102 and the second metal strip 103 are located at a corner of the bottom 1011 of the electronic device 100, and can be covered by a user when the user holds the electronic device 100, so that the human body functions as an FM antenna, and better signal coupling effect can be achieved, which is beneficial to improve the FM radio function.

[0023] The metal strip can be made of aluminum alloy, stainless steel, etc.

[0024] Please refer to Figure 2 , Figure 2 The first metal strip, the first side edge and the back plate are shown in the structural diagram of the embodiment. The length of the first metal strip 102 can be 10-15 mm, and the length of the second metal strip 103 can be 20-30 mm. The length D1 of the first metal strip 102 or the second metal strip 103 extending to the bottom 1011 is 5-8 mm.

[0025] The width D2 of the first metal strip 102 or the second metal strip 103 is 3-5 mm, and the thickness D3 is about 1 mm.

[0026] The first metal strip 102 or the second metal strip 103 occupies a corner of the bottom 1011 of the electronic device 100 and extends along the first side edge 1012 and the second side edge 1014 of the electronic device 100. Specifically, taking the first metal strip 102 as an example, the length of the first metal strip 102 corresponding to the bottom 1011 is 5-8 mm, and the length of the first metal strip 102 corresponding to the first side edge 1012 is 10-20 mm, which passes around the corner of the frame 101 of the electronic device 100. As can be seen, the first metal strip 102 occupies a corner of the bottom 1011 and a part of the first side edge 1012 of the frame 101, so that the first metal strip 102 can be covered by the user when the user holds the electronic device 100, thereby better enhancing the FM receiving effect of the antenna radiator.

[0027] The material of the frame 101 is an insulating material. The first metal strip 102 is located inside the first side 1012 and the bottom 1011. The second metal strip 103 is located inside the second side 1014 and the bottom 1011. That is, the frame 101 and the first metal strip 102 are injection molded by insert molding, specifically, the first metal strip 102 is fixed in the injection mold in advance, and then plastic is injected for molding. The frame 101 and the second metal strip 103 are also injection molded by insert molding. The first metal strip 102 is clamped between the first side 1012 and the inside of the bottom 1011, and the second metal strip 103 is clamped between the second side 1014 and the inside of the bottom 1011. In the direction perpendicular to the thickness of the electronic device 100, the distance D6 between the first metal strip 102 and the outer surface of the first side 1012 is less than or equal to 0.8mm, and the distance D5 between the first metal strip 102 and the inner surface of the first side 1012 is less than or equal to 0.8mm, and similarly, the distance between the second metal strip 103 and the outer surface of the second side 1014 is less than or equal to 0.8mm, and the distance between the second metal strip 103 and the inner surface of the second side 1014 is less than or equal to 0.8mm. As can be seen, the plastic wrapping layer outside the first metal strip 102 and the second metal strip 103 is very thin, and the FM signal can be transmitted between the user and the first metal strip 102 (the second metal strip 103) through coupling, so when the user holds the electronic device 100, the user's hand covers the first metal strip 102 and the second metal strip 103, and the human body acts as an FM antenna function, which can enhance the FM receiving effect.

[0028] As can be seen, the first metal strip 102 is embedded in the first side 1012, and the second metal strip 103 is embedded in the second side 1014, and the first metal strip 102 and the second metal strip 103 are respectively wrapped by the first side 1012 and the second side 1014, which cannot be seen on the appearance of the electronic device 100, and will not be in direct contact with the user, and the user will not directly conduct the first metal strip 102 and the second metal strip 103, and the current will not directly flow between the user, the first metal strip 102 and the second metal strip 103.

[0029] Taking the first metal strip 102 as an example, in the thickness direction of the electronic device 100, the width of the first side 1012 and the bottom 1011 is 8mm, and the width of the first metal strip 102 is 4mm. The distance D7 between the first metal strip 102 and the surface of the first side 1012 in the thickness direction of the electronic device 100 is 2mm. The second metal strip 103 has the same setting as the first metal strip 102, which will not be described here.

[0030] Please continue to refer to Figure 1The electronic device 100 further comprises a cover plate 104, a first circuit board 105 and an FM chip 106. The cover plate 104 and the frame 101 form a containing space. The first circuit board 105 is arranged in the containing space and close to the top 1013. The FM chip 106 is arranged on the first circuit board 105, and the FM chip 106 is electrically connected with the first metal strip 102. For example, viewed from the side of the cover plate 104, the first metal strip 102 is arranged on the right side of the electronic device 100, and the second metal strip 103 is arranged on the left side of the electronic device 100. Because most users are used to holding the electronic device 100 with the right hand, when the user holds the electronic device 100, the right hand can cover the second metal strip 103, and the second metal strip 103 is at the end of the FM antenna radiator, and the hand covering can achieve better signal coupling effect, which is conducive to the performance improvement of the FM antenna radiator.

[0031] In some scenarios, when the user does not hold the electronic device 100, the first metal strip 102 and the second metal strip 103 serve as the FM antenna radiator to receive signals. When the user's hand holds the electronic device 100, the human body acts as the FM antenna radiator to couple the FM signal to the first metal strip 102 and the second metal strip 103 to the FM chip 106 on the first circuit board 105 for signal enhancement.

[0032] When used in an open environment, the external FM signal is strong, and even if the user puts the electronic device 100 in the clothes pocket, good FM listening effect can be achieved. At this time, the FM signal received by using the first metal strip 102 and the second metal strip 103 as the FM antenna radiator is already sufficient. When used in an indoor environment or the like, the external FM signal is weak, and at this time the user can hold the electronic device 100 in the hand, and at this time the human body enhances the FM signal receiving capability of the electronic device 100, so that good listening effect can be achieved.

[0033] The electronic device 100 further comprises a signal transmission line 107 extending along the first side 1012. One end of the signal transmission line 107 is connected with the FM chip 106, and the other end is connected with the first metal strip 102. The signal transmission line 107, the first metal strip 102 and the second metal strip 103 can jointly form the FM antenna radiator.

[0034] The signal transmission line 107 is used for transmitting the FM signal output by the FM chip 106 and receiving signals. The signal transmission line 107 can have no shielding layer, only an inner core and an outer wrapping insulating material layer.

[0035] The electronic device 100 also comprises a battery, which is arranged in the accommodating space. The signal transmission line 107 can be arranged between the battery and the first side edge 1012, and the distance between the signal transmission line 107 and the battery is approximately 1 mm, and the distance between the signal transmission line 107 and the first side edge 1012 is approximately 1 mm.

[0036] The material of the surrounding structure of the signal transmission line 107 is insulating material, so as to facilitate FM transmission.

[0037] Specifically, the electronic device 100 further comprises a first elastic sheet 108, which is arranged on the first circuit board 105 and electrically connected with the FM chip 106 and the signal transmission line 107.

[0038] The electronic device 100 further comprises a second circuit board 110 and a fourth elastic sheet 109, the second circuit board 110 is arranged in the accommodating space and close to the bottom 1011, and the fourth elastic sheet 109 is electrically connected with the signal transmission line 107 and the first metal strip 102 respectively.

[0039] The distance between the end of the first metal strip 102 close to the second metal strip 103 and the end of the second metal strip 103 close to the first metal strip 102 is greater than or equal to 40 mm, for example, 50 mm.

[0040] Therefore, the first metal strip 102 and the second metal strip 103 are arranged in a spaced manner, which can provide a reserved position for the cellular communication antenna, i.e., corresponding to the bottom 1011 of the frame 101, the cellular communication antenna is arranged in the middle position, and the first metal strip 102 and the second metal strip 103 are arranged on both sides of the cellular communication antenna, so that the FM and the cellular communication antenna can coexist in the bottom 1011.

[0041] The electronic device 100, for example, a mobile phone, uses a communication antenna, i.e., a cellular communication antenna, for daily telephone and data browsing, and the middle position of the bottom 1011 of the electronic device 100 is a position that is more conducive to the performance of the antenna. Reserving this position for the cellular communication antenna can ensure that the basic telephone and data browsing functions of the mobile phone are not affected.

[0043] The signal transmission line 107 can also be a third metal strip 112, which is integrally formed with the first metal strip 102. The third metal strip 112 is directly electrically connected with the FM chip 106, or the third metal strip 112 is electrically connected with the FM chip 106 through the fourth elastic sheet 109.

[0044] The electronic device 100 further comprises a second circuit board 110 and a feed line 111, the second circuit board 110 is arranged in the accommodating space and is close to the bottom 1011, the feed line 111 is arranged on the second circuit board 110, and the feed line 111 is electrically connected with the first metal strip 102 and the second metal strip 103 respectively. The second circuit board 110 can be an antenna circuit board. The signal transmission line 107, the first metal strip 102, the feed line 111 and the second metal strip 103 can jointly form an FM antenna radiator.

[0045] The first metal strip 102 and the second metal strip 103 are electrically connected through the feed line 111 on the second circuit board 110. The feed line 111 is wrapped by GND (ground terminal of wire), the feed line 111 has an impedance of 50Ω, for example, the feed line 111 can be a microstrip line. By connecting the first metal strip 102 and the second metal strip 103 through the feed line 111, the normal transmission of FM can be maintained. The feed line 111 is fixed on the second circuit board 110, which can improve the reliability of the structure and save the internal space of the electronic device 100.

[0046] The electronic device 100 further comprises a second elastic sheet and a third elastic sheet, the second elastic sheet and the third elastic sheet are arranged on the second circuit board 110 in a spaced manner, one end of the feed line 111 is connected with the second elastic sheet, the other end is connected with the third elastic sheet, the first metal strip 102 is connected with the second elastic sheet, and the second metal strip 103 is connected with the third elastic sheet.
