For example, the first camera and the second camera are used to distinguish different cameras rather than to describe a specific order of cameras.

In addition, in the description of the embodiments of the present invention, unless otherwise specified, the meaning of "multiple" refers to two or more.

[0039] The solution provided by the utility model can be used in application scenarios in which electronic devices are used in daily production or daily life to transmit signals to be transmitted through their own signal transmission modules. For ease of understanding, the application scenarios involved in the embodiments of the utility model are first briefly introduced below.

[0040] With the rapid development of science and technology, various electronic devices have appeared in people's daily lives. People can use electronic devices to establish connections in various ways such as networks and communications, and share the data they want to transmit through these connections.

[0041] Please refer to Figure 1 , which shows a schematic diagram of a scenario of network communication of an electronic device involved in an exemplary embodiment of the utility model. Figure 1 As shown, various electronic devices 101 are included therein.

[0042] Optionally, the electronic device 101 can be a mobile phone, a tablet computer, smart glasses, a smart watch, an MP3 player (Moving Picture Experts Group Audio Layer III), an MP4 (Moving Picture Experts Group Audio Layer IV) player, or the like, and one of the electronic devices can establish a network connection with other electronic devices through a communication network.

[0043] Optionally, the communication network can be a wired network or a wireless network. Optionally, the wireless network or wired network mentioned in the utility model uses standard communication technology and / or protocol. The network is usually the Internet, but it can also be any network, including but not limited to any combination of a local area network (LAN), a metropolitan area network (MAN), a wide area network (WAN), a mobile, wired or wireless network, a dedicated network or a virtual private network. In some embodiments, the data exchanged through the network is represented by technologies and / or formats including Hyper Text Mark-up Language (HTML), Extensible Markup Language (XML), etc. In addition, conventional encryption technologies such as Secure Socket Layer (SSL), Transport Layer Security (TLS), Virtual Private Network (VPN), Internet Protocol Security (IPsec) can also be used to encrypt all or some links. In other embodiments, customized and / or dedicated data communication technologies can also be used to replace or supplement the above-mentioned data communication technologies.

[0044] Among them, electronic devices such as mobile phones, smart watches, smart bracelets and other mobile communication terminal products usually need to support multi-mode and multi-frequency networks such as Global System for Mobile Communications (GSM), Wideband Code Division Multiple Access (WCDMA), Long Term Evolution (LTE), and New Radio (NR). Electronic devices need to have corresponding RF power amplifiers (PA) and RF switches for frequency band selection in hardware.

[0045] Please refer to Figure 2 , which shows a schematic diagram of the structure of an integrated circuit chip involved in an exemplary embodiment of the utility model. Figure 2 As shown, it includes an amplifier 201, a radio frequency switch 202, and various antenna interfaces 203. Figure 2 In the embodiment, the RF switch 202 may be a single-pole multi-throw type switch.

[0046] Generally, when different electronic devices want to transmit data based on the GSM network, the electronic device on the transmitting end needs to amplify the signal to be transmitted through the amplifier 201, and transmit it to the RF switch 202 after amplification, and the RF switch 202 turns on one of the antenna interfaces to transmit it. In the GSM network, the most common signal formats are GSM850, Extended Global System for Mobile (EGSM), Distributed Control System (DCS), and Personal Communications Service (PCS), with frequencies of 850MHz, 900MHz, 1800MHz, and 1900MHz respectively.

[0047] Optional, in the above Figure 2 In the present invention, electronic devices need to support the frequency bands below 960MHz and above 1710MHz to work simultaneously. However, in electronic devices, the signal to be transmitted is always output through a main port, and the switching switch inside the signal transceiver module selects which antenna to transmit. Since it is always output through a main port, it is not suitable for scenarios with changing frequencies, and there is a problem of inflexible signal transmission.

[0048] In order to solve the technical problems existing in the above-mentioned related technologies and improve the flexibility of electronic devices in transmitting signals to be transmitted, the utility model provides a signal transmission module, which can be connected to an external device through a first transmission interface, or can be connected to an internal first transmission module, and flexibly transmitted to the required device to achieve diversified design.

[0049] Please refer to Figure 3 , which shows a schematic diagram of the structure of a signal transmission module provided by an exemplary embodiment of the utility model. Figure 3 As shown, the signal transmission module 300 includes: a power amplification module 301, a first transmission module 302, and a first transmission interface 303;

[0050] exist Figure 3 In the embodiment, the output end of the power amplifier module 301 is electrically connected to the first transmitting interface 303; the power amplifier module 301 is used to amplify the signal to be transmitted and transmit it through the first transmitting interface 303. The first transmitting interface 303 is used to connect to the first transmitting module 302; or, to connect to an external device. Among them, the external device is equivalent to other circuit positions set separately, and corresponding antennas, modules, signal processing and other settings can be set at other circuit positions, so as to further process or transmit the received signal to be transmitted.

[0051] Optionally, the first transmitting interface 303 is formed by adjusting the circuit structure based on an original interface of the signal transmitting module. For example, a signal transmitting module usually includes multiple grounding interfaces or grounding pins. This solution can adjust the original grounding interface to form a first transmitting interface, so that the signal to be transmitted can be transmitted from the first transmitting interface to an external device or to the internal first transmitting module, thereby achieving a flexible transmission effect.

[0052] Optionally, when the first transmitting interface 303 is connected to the first transmitting module 302, the first transmitting interface 303 is disconnected from the external device, and the amplified signal to be transmitted is transmitted to each antenna unit of the first transmitting module 302 through the first transmitting interface 303 and transmitted; when the first transmitting interface 303 is connected to the external device, the first transmitting interface 303 is disconnected from the first transmitting module 302, and the amplified signal to be transmitted is transmitted to the external device through the first transmitting interface 303.

[0053] It should be noted that the external device is an electronic device independent of the signal transmission module, and can be an independent antenna, module or other device, so as to achieve selective transmission of the signal to be transmitted, without having to transmit according to each antenna in the fixed first transmission module, thereby realizing flexibility and diversity in the transmission of the signal to be transmitted.

[0054] In summary, the signal transmission module provided by the utility model includes: a power amplifier module, a first transmission module, and a first transmission interface; the output end of the power amplifier module is electrically connected to the first transmission interface; the power amplifier module is used to amplify the signal to be transmitted and transmit it through the first transmission interface; the first transmission interface is used to connect to the first transmission module; or, to connect to an external device. By electrically connecting the output end of the power amplifier module in the signal transmission module to the first transmission interface, and by setting the first transmission interface, it is possible to connect to the original first transmission module or to connect to the set external device, so that the signal to be transmitted can be selectively transmitted through each antenna unit in the first transmission module, and can also be transmitted to the external device, so as to adapt to different transmission requirements, and it is not necessary to transmit according to each antenna in the fixed first transmission module, thereby improving the flexibility of signal transmission.

[0055] In one possible implementation, the above Figure 3 When the signal transmission module shown is actually used, the developer can flexibly manually set the first transmission interface, or the developer can set a control module to control whether the first transmission interface is connected to the first transmission module or to an external device.

[0056] Please refer to Figure 4 , which shows a schematic diagram of the structure of a signal transmission module involved in an exemplary embodiment of the utility model. Figure 4 As shown, the signal transmission module 400 includes: a power amplification module 401 , a first transmission module 402 , a first transmission interface 403 , and a first control interface 404 .

[0057] Among them, Figure 4 As shown, the power amplifier module 401 includes a high-frequency amplifier unit 401a and a low-frequency amplifier unit 401b; the output end of the high-frequency amplifier unit 401a is electrically connected to the first transmitting interface 403; the output end of the low-frequency amplifier unit 401b is electrically connected to the first transmitting module 402. That is, the electrical connection between the output end of the power amplifier module 401 and the first transmitting interface 403 is based on the connection of the output end of the high-frequency amplifier unit 401a. If the signal to be transmitted is a high-frequency signal, after being amplified by the high-frequency amplifier unit in the power amplifier, it can be selectively transmitted to the first transmitting module or to an external device through the first transmitting interface, so as to achieve flexible selection. For the low-frequency signal to be transmitted, it can be directly connected to the first transmitting module 402 and transmitted through the first transmitting module 402.

[0058] Optionally, in this solution, the signal to be transmitted is a communication signal in a GSM network. A high-frequency signal may refer to a frequency band above 1710 MHz, and a low-frequency signal may refer to a frequency band below 960 MHz. For different high-frequency signals, the signal transmission module provided by the utility model can be flexibly transmitted through an external device or a first transmission module, and does not always need to be transmitted through the first transmission module inside the module, thereby improving the adaptability of signal transmission.

[0059] The first transmitting module 402 further includes at least one antenna unit 402a and a radio frequency selection unit 402b; the radio frequency selection unit 402b is further used to select a required radio frequency path to be connected to the at least one antenna unit 402a.

[0060] In the above Figure 4 In the embodiment, at least one antenna unit 402a in the first transmitting module 402 is connected via the antenna pin ANT. In the RF selection unit 402b, interfaces TRX1 to TRX14 of various selectable RF paths are included, and the selection switch can flexibly select a RF path connected to one of the interfaces, so that the selected RF path is connected to the at least one antenna unit 402a, and can provide a corresponding RF signal.

[0061] Optionally, in the first transmitting module 402, the above-mentioned multiple RF paths and the interfaces through the multiple RF paths are exemplary, and the selection switch can be a single-pole multi-throw switch, which can be flexibly designed in practical applications, and the specific number and structure are not limited here.

[0062] Optionally, the first control interface 404 is electrically connected to the first transmitting module 402. In the present invention, in order to reduce the design of circuit routing, a first control interface 404 can be provided like the first transmitting interface, and the first transmitting interface 403 can be connected or disconnected with the first control interface 404 by being electrically connected with the first transmitting module 402, thereby realizing the control of the first transmitting interface and the first transmitting module being connected or disconnected.

[0063] For example, when using the signal transmission module, developers can set a single-pole double-throw switch, one side of which can be connected to the path connected to the external device, and the other side of which can be connected to the path connected to the first control interface 404, so as to achieve switching between the external device and the first transmission module, so that the signal to be transmitted is connected to the external device, or the signal to be transmitted is connected to the first transmission module. The signal to be transmitted is transmitted in a selected manner.

[0064] Optionally, the first transmitting interface and the first control interface mentioned above can be formed by adjusting the circuit structure based on the original ground interface of the signal transmitting module.

[0065] Please refer to Figure 5 , which shows that an exemplary embodiment of the utility model relates to Figure 4 A schematic diagram of the interface structure of an integrated circuit. Figure 5 As shown, it includes various functional interfaces 501 and grounding interfaces 502. Figure 4 In the schematic diagram of the various interfaces of the integrated circuit, the signal transmission module shown is presented, and each functional interface 501 may include the connection end of each antenna unit in the first transmission module, the input end of the power amplifier module, etc. In the integrated circuit, in order to make the circuit work normally, the multiple grounding interfaces 502 set can be grounded. In the utility model, two of the grounding interfaces can be used as the first transmission interface and the first control interface respectively. On the basis of the original grounding interface, the output end of the high-frequency amplification unit in the power amplifier module is connected to the first transmission interface, and the first transmission module is connected to the first control interface to adjust the circuit. The two grounding interfaces can be renamed as the first transmission interface and the first control interface.

[0066] Please refer to Figure 6 , which shows that an exemplary embodiment of the utility model relates to Figure 5 Another schematic diagram of the interface structure of an integrated circuit. Figure 6 As shown, for the above Figure 5 After adjustment, the two original grounding interfaces are set to be the first transmitting interface 601 and the first control interface 602. The first transmitting interface 601 is named as the GSM HB OUT interface and can be introduced to other positions of the circuit. The first control interface 602 can be named as the TRX 15 interface and can be connected to the first transmitting module.

[0067] Optionally, the above-mentioned control of the connection between the first transmitting interface and the first transmitting module, or the control of the connection between the first transmitting interface and the external device, in addition to manual control by the developer or user, can also be achieved through a control module. For example, in one possible implementation method, the signal transmission module provided by the utility model also includes a control module; the control module is used to control the connection or disconnection of the first transmitting interface and the first transmitting module; and control the connection or disconnection of the first transmitting interface and the external device. In the above-mentioned scheme of the first control interface, the control module is also used to control the conduction or disconnection of the first transmitting interface and the first control interface to achieve control of the conduction or disconnection of the first transmitting interface and the first transmitting module.

[0068] Optionally, the control module can be separately set inside or outside the signal transmission module to separately control how the first transmission interface is connected. If it is necessary to control the first transmission interface to be connected to the first transmission module, it can be achieved by executing corresponding control instructions. Of course, if it is necessary to control the first transmission interface to be connected to an external device, it can also be achieved by executing corresponding control instructions. For example, in the above Figure 5 or Figure 6 In the process, it is only necessary to control whether the double-pole switch is hit at the first control interface or at the connection with the external device.

[0069] Optionally, the external device mentioned above is equivalent to other circuit positions that are set separately, and corresponding antennas, modules, signal processing and other settings can be set at other circuit positions to further process or transmit the received signal to be transmitted. For example, the external device includes an antenna unit, and the external device is used to transmit the received signal to be transmitted through its own antenna unit.

[0070] In one possible implementation, the control module is also used to obtain the frequency of the signal to be transmitted, and when the frequency of the signal to be transmitted is higher than a preset power threshold, control the first transmitting interface to be connected to the external device. For example, in the signal transmission module, the control module can obtain the frequency of the signal to be transmitted and detect the frequency. If the frequency of the signal to be transmitted is higher than the preset power threshold, the first transmitting interface can be controlled to be connected to the external device so that the high-frequency signal to be transmitted is transmitted through the external device. Among them, the preset power threshold can be pre-set by the developer. For example, the preset power threshold is 1700MHz. Optionally, if the frequency of the signal to be transmitted is not higher than the preset power threshold, the first transmitting interface can be controlled to be connected to the first transmitting module and transmitted through one of the antenna units of the first transmitting module.

[0071] In one possible implementation, the control module is also used to obtain signal interference data, which includes signal interference between the signal to be transmitted and the signals being transmitted in each antenna unit of the first transmitting module; the control module is also used to control the first transmitting interface to be connected to the external device when the signal interference data exceeds a preset interference threshold.

[0072] For example, in the signal transmission module, the control module can also obtain signal interference data and detect the signal interference data. If the interference data exceeds the preset interference threshold, the first transmission interface can be controlled to be connected to the external device so that the signal to be transmitted is transmitted through the external device to avoid mutual interference between signals. Among them, the preset interference threshold can also be pre-set by the developer. Optionally, if the interference data does not exceed the preset interference threshold, the first transmission interface can be controlled to be connected to the first transmission module and transmitted through one of the antenna units of the first transmission module.

[0073] In one possible implementation, the above Figure 4 When the signal transmitting module transmits a signal, if the signal transmitted from the low-frequency amplifying unit to the first transmitting module is transmitted through the first antenna unit, the signal transmitting module also needs to transmit the signal to be transmitted transmitted by the high-frequency amplifying unit. The control module can obtain the signal interference between the signal to be transmitted and the signal transmitted by the first antenna unit, thereby obtaining the signal interference data required here, and detecting the signal interference data. If the interference data exceeds the preset interference threshold, the first transmitting interface can be controlled to be connected to the external device, and the high-frequency signal can be controlled to be transmitted through the external device to avoid mutual interference with the signal transmitted by the first antenna unit, thereby improving the accuracy of the transmission.

[0074] Of course, the above calculation of the signal interference between the two signals is exemplary. In actual applications, if multiple antenna units of the first transmitting module are transmitting signals, the control module can also calculate the signal interference between the signals transmitted by the multiple antenna units and the current signal to be transmitted. If one of the signal interference exceeds the preset interference threshold, it can be regarded as interference data exceeding the preset interference threshold, thereby controlling the first transmitting interface to be connected to the external device and controlling the high-frequency signal to be transmitted through the external device.

[0075] That is to say, the control module is used to control the conduction or disconnection between the first transmitting interface and the first transmitting module; and to control the conduction or disconnection between the first transmitting interface and the external device; wherein, when the first transmitting interface and the first transmitting module are connected, the first transmitting interface and the external device are disconnected, and the amplified signal to be transmitted is transmitted to each antenna unit of the first transmitting module through the first transmitting interface and transmitted; when the first transmitting interface and the external device are connected, the first transmitting interface and the first transmitting module are disconnected, and the amplified signal to be transmitted is transmitted to the external device through the first transmitting interface.

[0076] Optional, please refer to Figure 7 , which shows that an exemplary embodiment of the utility model relates to Figure 4 A schematic diagram of the structure of another integrated circuit. Figure 7 In the embodiment, the signal transmission module 700 includes: a power amplification module 701, a first transmission module 702, a first transmission interface 703, a first control interface 704, and a signal controller 705. The circuits are connected in the following manner: Figure 7 By setting the first transmitting interface 703 and the first control interface 704 to work according to the above principle, the signal to be transmitted is selectively transmitted from each antenna unit in the first transmitting module, or transmitted to an external device and transmitted by the antenna of the external device, which will not be repeated here.

[0077] in, Figure 7 The signal controller 705 may be a complementary metal oxide semiconductor (CMOS) controller in an integrated circuit, and may be used to provide signals received based on a mobile industry processor interface (MIPI) protocol. Figure 7 is equivalent to Figure 4 A more detailed circuit structure diagram, of course, the above Figure 7 The structure in can also be applied to Figure 5 and Figure 6 middle.

[0078] exist Figure 7 In the process, high-frequency signals are input through high-frequency pins HB_SWOUT and TX_HB_IN, and low-frequency signals are input through low-frequency pins LB_SWOUT and TX_LB_IN. The VCC and / or VBATT interfaces are connected to the power supply for operation. The VRAMP, VIO, SCLK, and SDATA pins transmit the signals required by the MIPI protocol respectively.

[0079] In summary, the signal transmission module provided by the utility model includes: a power amplifier module, a first transmission module, and a first transmission interface; the output end of the power amplifier module is electrically connected to the first transmission interface; the power amplifier module is used to amplify the signal to be transmitted and transmit it through the first transmission interface; the first transmission interface is used to connect to the first transmission module; or, to connect to an external device; wherein, when the first transmission interface is connected to the first transmission module, the first transmission interface is disconnected from the external device, and the amplified signal to be transmitted is transmitted to each antenna unit of the first transmission module through the first transmission interface and transmitted; when the first transmission interface is connected to the external device, the first transmission interface is disconnected from the first transmission module, and the amplified signal to be transmitted is transmitted to the external device through the first transmission interface. By electrically connecting the output end of the power amplifier module in the signal transmission module to the first transmission interface, and by setting the first transmission interface, it is realized to connect to the original first transmission module or to connect to the set external device, so that the signal to be transmitted can be selectively transmitted through each antenna unit in the first transmission module, and can also be transmitted to the external device, so as to adapt to different transmission requirements, and it is not necessary to transmit according to each antenna in the fixed first transmission module, thereby improving the flexibility of signal transmission.

[0082] The processor 810 is the control center of the electronic device, and uses various interfaces and lines to connect various parts of the entire electronic device. By running or executing software programs and / or modules stored in the memory 820, and calling data stored in the memory 820, the processor 810 performs various functions of the electronic device and processes data, thereby monitoring the electronic device as a whole.
