Due to the high power of GSM itself, it is easy to cause stray radiation to exceed the standard. In the prior art, mobile terminals and other electronic devices that rely on antennas to radiate signals, with the development of portability and intelligence, electronic devices with multiple functions are integrated in mobile terminals, and the distance between these electronic devices and antennas is limited by the arrangement space. closer. For example, a Universal Serial Bus (Universal Serial Bus, USB) socket, a fingerprint chip, and the like. Generally speaking, the antenna is connected to the excitation source, and the excitation source is used to generate the excitation signal, and transmit the excitation signal to the antenna, and the antenna receives the excitation signal and generates an electromagnetic wave signal of a predetermined frequency (for example, GSM900GHZ ), and radiate the electromagnetic wave signal of the predetermined frequency. Due to the short distance between the USB socket, fingerprint chip, etc. and the antenna, the electromagnetic wave signal of a predetermined frequency generated by the antenna will be coupled to these devices, and these devices are often nonlinear, and these nonlinear devices will couple the energy through nonlinear effects. Generate harmonics, such as the second harmonic (1800GHZ) or the third harmonic (2700GHZ). When the lengths of these nonlinear devices match the harmonics, the nonlinear devices can act as radiators to radiate the harmonics, thereby causing radiation spurious to exceed the standard.

图1为本申请第一实施例提供的移动终端的结构示意图。所述移动终端10包括但不仅限于智能手机、互联网设备(mobile internet device，MID)、电子书、便携式播放站(Play Station Portable,PSP)或个人数字助理(Personal Digital Assistant，PDA)等通信设备。所述移动终端10还具有指纹识别与USB数据连接的功能，换言之，所述移动终端10包括指纹模组210和USB座220。所述移动终端10包括天线100及金属体200。所述天线100用于接收激励信号，根据所述激励信号产生第一电磁波信号并将所述第一电磁波信号辐射出去。所述金属体200距离所述天线100预设距离，所述第一电磁波信号耦合到所述金属体上产生谐波。所述金属体200设至少两个接地点，以改变所述金属体200的电长度，使得所述金属体200无法将所述谐波辐射出去。FIG. 1 is a schematic structural diagram of a mobile terminal provided in a first embodiment of the present application. The mobile terminal 10 includes, but is not limited to, communication devices such as smart phones, Internet devices (mobile internet device, MID), e-books, portable playback stations (Play Station Portable, PSP) or personal digital assistants (Personal Digital Assistant, PDA). The mobile terminal 10 also has the functions of fingerprint identification and USB data connection, in other words, the mobile terminal 10 includes a fingerprint module 210 and a USB socket 220 . The mobile terminal 10 includes an antenna 100 and a metal body 200 . The antenna 100 is used to receive an excitation signal, generate a first electromagnetic wave signal according to the excitation signal, and radiate the first electromagnetic wave signal. The metal body 200 is at a preset distance from the antenna 100 , and the first electromagnetic wave signal is coupled to the metal body to generate harmonics. The metal body 200 is provided with at least two grounding points to change the electrical length of the metal body 200 so that the metal body 200 cannot radiate the harmonic.
相较于现有技术，本申请的所述金属体200上设置的接地点的数目至少为两个，改变了金属体200的电长度，从而使得所述金属体200与辐射所述谐波所需要的尺寸不匹配，进而使得所述第一电磁波耦合到所述金属体200上产生的谐波无法辐射出去。进一步地，由于所述金属体200接地，可以使得所述第一电磁波信号耦合到所述金属体200上而产生的谐波传导至地极，从而消除所述谐波。Compared with the prior art, the number of grounding points set on the metal body 200 of the present application is at least two, which changes the electrical length of the metal body 200, so that the metal body 200 is compatible with the harmonic radiation. The required dimensions do not match, so that the harmonic generated by the coupling of the first electromagnetic wave to the metal body 200 cannot be radiated. Further, since the metal body 200 is grounded, the harmonics generated by the coupling of the first electromagnetic wave signal to the metal body 200 can be conducted to the ground, thereby eliminating the harmonics.
在本实施方式中，所述移动终端10还包括激励源300。所述激励源300用于产生激励信号，并将所述激励信号输出。所述天线100与所述激励源300电连接，用于接收所述激励信号，并根据所述激励信号产生第一电磁波信号，且所述天线100用于将所述第一电磁波信号辐射出去。由于所述金属体200距离所述天线100预设距离，位于所述天线100预设距离的金属体200通过耦合的方式接收所述第一电磁波信号，并由于所述金属体200的非线性作用，所述金属体200根据所述第一电磁波信号而产生谐波，若所述金属体200的电长度与辐射所述谐波所需的尺寸匹配的话，则所述金属体200则可以作为辐射体将所述谐波辐射出去，进而导致辐射杂散超标。举例而言，所述第一电磁波信号的频率为900GHZ，所述谐波可以为二次谐波(1800GHZ)或者三次谐波(2700GHZ)等，所述谐波构成了所述第一电磁波信号的辐射杂散。In this embodiment, the mobile terminal 10 further includes an excitation source 300 .

The antenna 100 is electrically connected to the excitation source 300 for receiving the excitation signal and generating a first electromagnetic wave signal according to the excitation signal, and the antenna 100 is used for radiating the first electromagnetic wave signal. Since the metal body 200 is at a preset distance from the antenna 100, the metal body 200 located at a preset distance from the antenna 100 receives the first electromagnetic wave signal through coupling, and due to the nonlinear effect of the metal body 200 , the metal body 200 generates harmonics according to the first electromagnetic wave signal, and if the electrical length of the metal body 200 matches the size required for radiating the harmonics, the metal body 200 can act as a radiation The body radiates the harmonics, which leads to excessive radiation spurious. For example, the frequency of the first electromagnetic wave signal is 900GHZ, the harmonic may be the second harmonic (1800GHZ) or the third harmonic (2700GHZ), etc., and the harmonic constitutes the frequency of the first electromagnetic wave signal radiation spurious.

For a rectangular metal body 200 , the electrical length of the metal body 200 is the length of the long side of the metal body 200 . For the arc-shaped metal body 200, the electrical length of the metal body 200 is the perimeter of the metal strip.

When the camera 700 is turned on to take pictures or shoot videos, when the light in the environment where the mobile terminal 10 is located is relatively dark, the brightness of the captured image or video is relatively dark, and the shooting effect of the image or video is not good. . The flash 800 is turned on to compensate for ambient light. To increase the brightness of the image or video captured by the camera 700 . Understandably, the mobile terminal 10 may not include the flashlight 800 , that is, the flashlight 800 is not an essential component of the mobile terminal 10 .
