Detailed Implementation

[0058] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this invention. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this invention as detailed in the appended claims. It should also be understood that the term “and / or” as used herein refers to and includes any or all possible combinations of one or more of the associated listed items.

[0059] With the development of electronic devices, portless electronic devices without interfaces have emerged to avoid damage caused by wear or corrosion of interfaces. Because portless electronic devices lack interfaces, they can only project images to display devices wirelessly. For example, electronic devices and display devices can project images via Wireless Fidelity (WiFi). However, due to the slow signal transmission speed in WiFi, electronic devices experience high latency and poor display quality when projecting images via WiFi.

[0060] Based on this, the present disclosure provides a transmission module that uses a first wireless transmission module with a fast transmission speed to replace a wireless fidelity module with a slow transmission speed for image projection. This allows the image to be transmitted at a faster speed, thereby reducing the delay in image projection and improving the effect of image projection.

[0061] An exemplary embodiment of this disclosure provides a transmission module, such as... Figure 1 As shown, the transmission module includes a control circuit 10 and a first wireless transmission module 20. The control circuit 10 is used to output the image to be projected. The first wireless transmission module 20 is electrically connected to the control circuit 10 and is used for wireless transmission of the image to the electronic device accessory 30 at close range, so as to project the image onto the screen via the electronic device accessory 30.

[0062] In this embodiment, the transmission module includes a control circuit and a first wireless transmission module. The control circuit is electrically connected to the first wireless transmission module and is used to output the image to be projected. The first wireless transmission module is used for wireless transmission of images to electronic device accessories at close range, so as to project the images via the electronic device accessories. Because the first wireless transmission module performs wireless transmission of images to electronic device accessories at close range, the image transmission speed is fast. By using the first wireless transmission module to wirelessly transmit images to electronic device accessories to achieve image projection, the images can be transmitted at a relatively fast speed, thereby reducing the delay of image projection and improving the effect of image projection.

[0063] For example, after the control circuit 10 wirelessly transmits images to the electronic device accessory 30, the electronic device accessory 30 can wirely transmit images to the electrically connected display device so as to display the projected images on the display device.

[0064] For example, the control circuit 10 includes a processor. Because the processor can perform signal processing efficiently, it can accelerate the speed of image transmission with the electronic device accessory 30, thereby reducing image projection latency. Furthermore, since the processor can be a processor within the electronic device, the complexity of the electronic device's structure is reduced by reusing the processor in the electronic device.

[0065] In one embodiment, such as Figure 2 As shown, the first wireless transmission module 20 includes a first sub-wireless transmission module 21 and a second sub-wireless transmission module 22. The first sub-wireless transmission module 21 is electrically connected to the control circuit 10. The second sub-wireless transmission module 22 is electrically connected to the control circuit 10. The transmission speed of the first sub-wireless transmission module 21 is greater than the transmission speed of the second sub-wireless transmission module 22.

[0066] In this embodiment, since the image needs to transmit various types of signals during transmission, some types of signals require faster transmission speeds while others do not. Because the transmission speed of the first sub-wireless transmission module is greater than that of the second sub-wireless transmission module, the cost of the transmission module is reduced while ensuring that the image projection effect meets the requirements.

[0067] For example, the signals that need to be transmitted during image transmission include image signals and auxiliary signals. The image signals carry the screen information of the image projection and need to be transmitted at a relatively high speed. The auxiliary signals carry auxiliary information for image projection and do not need to be transmitted at a relatively high speed. The first sub-wireless transmission module 21 is used to transmit image signals to the electronic device accessory 30, and the second sub-wireless transmission module 22 is used to wirelessly transmit auxiliary signals with the electronic device accessory 30.

[0068] For example, before the first sub-wireless transmission module 21 transmits the image signal to the electronic device accessory 30, the display device can transmit auxiliary information such as the supported resolution and bandwidth to the control circuit 10 through auxiliary signals, and the control circuit 10 can also transmit auxiliary information such as the feedback resolution and bandwidth to the display device through auxiliary signals.

[0069] In one embodiment, the number of first sub-wireless transmission modules 21 is N, where N is a positive integer greater than or equal to 1.

[0070] In this embodiment, by setting up multiple first sub-wireless transmission modules, the control circuit can selectively transmit images to some or all of the first sub-wireless transmission modules to project images onto the screen at an appropriate resolution, thereby improving the reliability of the transmission modules. Furthermore, by setting up multiple first sub-wireless transmission modules, images can be transmitted simultaneously to electronic device accessories through different transmission channels, thus improving the image projection effect.

[0071] For example, the number of first sub-wireless transmission modules 21 is related to the resolution supported by the image projection.

[0072] For example, such as Figure 3 As shown, there are four first sub-wireless transmission modules 21, and the highest resolution supported by the image projection is 4K. Because there are four first sub-wireless transmission modules, image signals can be transmitted simultaneously from four transmission channels, enabling the image projection to support a maximum resolution of 4K, thereby improving the display effect of the image projection.

[0073] For example, when the control circuit 10 transmits image signals to one first sub-wireless transmission module 21, the resolution of the image projection is 1K. When the control circuit 10 transmits image signals to two first sub-wireless transmission modules 21, the resolution of the image projection is 2K. When the control circuit 10 transmits image signals to four first sub-wireless transmission modules 21, the resolution of the image projection is 4K.

[0074] In one embodiment, the signals that need to be transmitted during image transmission also include hot-plug signals. The second sub-wireless transmission module 22 is also used for wireless transmission of hot-plug signals with the electronic device accessory 30.

[0075] In this embodiment, since the hot-plug signal reflects the connection status between the display device and the electronic accessory, the control circuit can determine whether the display device is connected based on the hot-plug signal to determine whether to continue image projection. When the display device and the electronic accessory are connected, the transmission module transmits images to the electronic accessory. When the display device and the electronic accessory are not connected, the transmission module stops transmitting images to the electronic accessory. By transmitting the hot-plug signal, the plug-and-play function of the display device is realized, thereby improving the reliability and security of image projection.

[0076] In one embodiment, there are multiple second sub-wireless transmission modules 22, and each second sub-wireless transmission module 22 is electrically connected to the control circuit 10.

[0077] In this embodiment, since images need to transmit various types of signals during transmission, multiple second sub-wireless transmission modules are configured to enable wireless transmission of these signals with electronic device accessories. Furthermore, because the multiple second sub-wireless transmission modules and electronic device accessories have different transmission channels, different types of signals can be transmitted through these channels, avoiding mutual interference and improving the reliability of the transmission modules.

[0078] For example, some of the second sub-wireless transmission modules 22 are used for wireless transmission of auxiliary signals with the electronic device accessory 30, and some are used for wireless transmission of hot-plug signals with the electronic device accessory 30. Because multiple second sub-wireless transmission modules are provided, wireless transmission of both auxiliary and hot-plug signals with the electronic device accessory is possible. Before transmitting images to the electronic device accessory, the relevant information for image projection can be determined separately through the hot-plug signal and the auxiliary signal, thereby improving the reliability of image projection. Furthermore, since the hot-plug signal carries the connection information of the display device, it does not need to be transmitted at a high speed. Transmitting the hot-plug signal through the slower-speed second sub-wireless transmission modules reduces the cost of the transmission module while ensuring that the image projection effect meets requirements. Simultaneously, since multiple second sub-wireless transmission modules have different transmission channels with the electronic device accessory, the hot-plug signal and the auxiliary signal can be transmitted through different transmission channels, avoiding mutual interference and improving the reliability of the transmission module.

[0079] In one embodiment, such as Figure 4 As shown, there is one second sub-wireless transmission module 22. The transmission module also includes a first signal processing module 40. The first signal processing module 40 is electrically connected between the second sub-wireless transmission module 22 and the control circuit 10, and is electrically connected to the second sub-wireless transmission module 22 via a first signal line. The first signal processing module 40 is electrically connected to the control circuit 10 via a second signal line, a third signal line, and a fourth signal line.

[0080] In this embodiment, by setting up a first signal processing module to merge and recover signals, only a second sub-wireless transmission module is needed for signal transmission, thereby reducing the complexity of the transmission module structure.

[0081] For example, to prevent the first sub-wireless transmission module 21 and the second sub-wireless transmission module 22 from failing to transmit signals properly due to mutual interference, the distance between the multiple first sub-wireless transmission modules 21 and the distance between the first sub-wireless transmission module 21 and the second sub-wireless transmission module 22 need to meet the requirements of a preset spacing.

[0082] For example, the first signal processing module 40 is used to combine the auxiliary signal and the hot-plug signal output by the control circuit 10 into a first signal and transmit it to the second sub-wireless transmission module 22, and to restore a second signal transmitted by the electronic device accessory 30 through the second sub-wireless transmission module 22 into an auxiliary signal and a hot-plug signal and transmit it to the control circuit 10.

[0083] In one embodiment, the first wireless transmission module 20 transmits wireless signals to the electronic device accessory 30 via millimeter-wave communication.

[0084] In this embodiment, because the signal transmission speed is fast and the transmission distance is short under millimeter wave communication, the first wireless transmission module and electronic device accessories can transmit a large number of signals in a short time and prevent wireless connection with incorrect electronic device accessories, thereby improving the efficiency and reliability of the transmission module.

[0085] An exemplary embodiment of this disclosure provides an electronic device, which includes the transmission module described above.

[0086] For example, the electronic device can be a mobile phone, a laptop, a tablet, or a wearable device.

[0087] In one embodiment, such as Figure 5 As shown, the electronic device also includes a first housing 50 and a first adsorption unit. A transmission module is disposed within the first housing 50. The first adsorption unit, disposed within the first housing 50, is used to adsorb the electronic device accessory 30.

[0088] In this embodiment, to facilitate matching between the electronic device and its accessories, a first adsorption part is provided within the first housing of the electronic device for matching with the adsorbed electronic device accessories. By providing a first adsorption part within the electronic device to adsorb the electronic device accessories, matching with the electronic device accessories only occurs after adsorption, avoiding mismatching and thus improving the reliability of the electronic device. Simultaneously, since millimeter-wave communication has a short range, matching with electronic device accessories via adsorption allows the electronic device to wirelessly transmit images with the accessories within an effective range, further enhancing the reliability of the electronic device. Furthermore, when users need wireless image transmission between the electronic device and its accessories, they only need to place the accessories on the electronic device, thus reducing the complexity of image transmission.

[0089] For example, the first housing 50 of the electronic device does not have a Universal Serial Bus (USB) interface for data transmission. The USB interface could be, for example, a Type-C interface. That is, the electronic device cannot be electrically connected to a data cable via a wired connection.

[0090] In one embodiment, the first adsorption unit includes a first magnetic adsorption unit 61 and a second magnetic adsorption unit 62. A first wireless transmission module 20 is disposed between the first magnetic adsorption unit 61 and the second magnetic adsorption unit 62.

[0091] In this embodiment, since only two magnetic units are needed to attract electronic device accessories, the first attraction part occupies less space in the electronic device, thereby reducing the complexity of the electronic device structure. Simultaneously, because the first wireless transmission module is positioned between the two magnetic units, after the electronic device accessories are attracted, the first and second wireless transmission modules can align for wireless signal transmission, thus improving the reliability of the electronic device.

[0092] For example, the polarities of the first magnetic unit 61 and the second magnetic unit 62 may be the same or different.

[0093] An exemplary embodiment of this disclosure provides an electronic device, such as... Figure 6 As shown, the electronic device includes a processor 420, a first sub-wireless transmission module 21, a second sub-wireless transmission module 22, a first signal processing module 40, a first housing 50, a first magnetic unit 61, and a second magnetic unit 62. There are four first sub-wireless transmission modules 21. The processor 420, the first sub-wireless transmission module 21, the second sub-wireless transmission module 22, the first signal processing module 40, the first magnetic unit 61, and the second magnetic unit 62 are all disposed within the first housing 50. The processor 420 is electrically connected to the first terminals of the four first sub-wireless transmission modules 21 and the first signal processing module 40, and the second terminal of the first signal processing module 40 is electrically connected to one second sub-wireless transmission module 22. The first sub-wireless transmission modules 21 and 22 are both disposed between the first magnetic unit 61 and the second magnetic unit 62.

[0094] An exemplary embodiment of this disclosure provides an electronic device accessory 30, such as... Figure 7 As shown, the electronic device accessory 30 includes a second wireless transmission module 31 and an interface 32. The second wireless transmission module 31 is used for wireless transmission of images to the electronic device 400 at close range. The first end of the interface 32 is electrically connected to the second wireless transmission module 31, and the second end of the interface 32 is used for electrical connection to the display device 70. The second wireless transmission module 31 transmits images to the display device 70 through the interface 32 for image projection.

[0095] In this embodiment, the electronic device accessory includes a second wireless transmission module and an interface. The interface is electrically connected between the second wireless transmission module and the display device. The second wireless transmission module is used for wireless image transmission with the electronic device at close range. Specifically, the second wireless transmission module transmits images to the display device through the interface for image projection. Because the second wireless transmission module transmits images wirelessly with the electronic device at close range, the image transmission speed is fast. By using the second wireless transmission module to wirelessly transmit images with the electronic device to achieve image projection, the image can be transmitted at a relatively fast speed, thereby reducing image projection latency and improving the image projection effect.

[0096] In one embodiment, such as Figure 8 As shown, the second wireless transmission module 31 includes a third sub-wireless transmission module 311 and a fourth sub-wireless transmission module 312. The third sub-wireless transmission module 311 is electrically connected to the interface 32. The fourth sub-wireless transmission module 312 is electrically connected to the interface 32. The transmission speed of the third sub-wireless transmission module 311 is greater than that of the fourth sub-wireless transmission module 312.

[0097] In this embodiment, since the image needs to transmit various types of signals during transmission, some types of signals require faster transmission speeds while others do not. Because the transmission speed of the third sub-wireless transmission module is greater than that of the fourth sub-wireless transmission module, the cost of electronic device accessories is reduced while ensuring that the image projection effect meets the requirements.

[0098] For example, the signals that need to be transmitted during image transmission include image signals and auxiliary signals. The image signals carry the screen projection information and need to be transmitted at a relatively high speed. The auxiliary signals carry auxiliary information for image projection and do not need to be transmitted at a relatively high speed. The third sub-wireless transmission module 311 is used to receive the image signals transmitted by the electronic device, and the fourth sub-wireless transmission module 312 is used to wirelessly transmit auxiliary signals with the electronic device 400.

[0099] For example, before the electronic device 400 transmits the image signal to the third sub-wireless transmission module 311, the display device 70 can transmit auxiliary information such as the supported resolution and bandwidth to the electronic device 400 through auxiliary signals, and the electronic device 400 can also transmit the feedback auxiliary information such as the resolution and bandwidth to the display device 70 through auxiliary signals.

[0100] In one embodiment, the number of third sub-wireless transmission modules 311 is N, where N is a positive integer greater than or equal to 1.

[0101] In this embodiment, by setting up multiple third sub-wireless transmission modules, the electronic device can selectively transmit images through some or all of the third sub-wireless transmission modules to project images onto the display device at a suitable resolution, thereby improving the reliability of the electronic device accessories. Furthermore, by setting up multiple third sub-wireless transmission modules, images can be transmitted to the electronic device accessories simultaneously through different transmission channels, thus improving the image projection effect.

[0102] For example, the number of third sub-wireless transmission modules 311 is related to the resolution supported by the image projection.

[0103] For example, such as Figure 9 As shown, there are four third-generation wireless transmission modules 311, and the highest resolution supported by the image projection is 4K. Because there are four third-generation wireless transmission modules, image signals can be transmitted simultaneously from four transmission channels, enabling the image projection to support a maximum resolution of 4K, thereby improving the display effect of the image projection.

[0104] For example, when electronic device 400 transmits image signals to one third sub-wireless transmission module 311, the resolution of the image projection is 1K. When electronic device 400 transmits image signals to two third sub-wireless transmission modules 311, the resolution of the image projection is 2K. When electronic device 400 transmits image signals to four third sub-wireless transmission modules 311, the resolution of the image projection is 4K.

[0105] In one embodiment, the signals that need to be transmitted during image transmission also include hot-plug signals. The fourth sub-wireless transmission module 312 is also used for wireless transmission of hot-plug signals with the electronic device 400.

[0106] In this embodiment, since the hot-plug signal reflects the connection status between the display device and the electronic device accessory, the electronic device can determine whether the display device is connected based on the hot-plug signal to decide whether to continue image projection. When the display device and the electronic device accessory are connected, the electronic device transmits images to the display device through the accessory. When the display device and the electronic device accessory are not connected, the electronic device stops transmitting images to the accessory. By transmitting the hot-plug signal, the plug-and-play function of the display device is achieved, thereby improving the reliability and security of image projection.

[0107] In one embodiment, there are multiple fourth sub-wireless transmission modules 312, and each fourth sub-wireless transmission module 312 is electrically connected to the interface 32.

[0108] In this embodiment, since images need to transmit various types of signals during transmission, multiple fourth sub-wireless transmission modules can be set up to enable wireless transmission of various signal types with the electronic device. Furthermore, because the multiple fourth sub-wireless transmission modules have different transmission channels with the electronic device, different signal types can be transmitted through different channels, avoiding mutual interference and improving the reliability of the electronic device accessories.

[0109] For example, some of the fourth sub-wireless transmission modules 312 are used for wireless transmission of auxiliary signals with electronic devices, and some are used for wireless transmission of hot-swap signals with electronic devices. Because multiple fourth sub-wireless transmission modules are provided, wireless transmission of both auxiliary and hot-swap signals with electronic devices is possible. Before transmitting image signals from the electronic device accessory, information related to image projection can be determined separately through the hot-swap signal and auxiliary signal, thereby improving the reliability of image projection. Furthermore, since the hot-swap signal carries the connection information of the display device, it does not need to be transmitted at a high speed. Transmitting the hot-swap signal through the slower-speed fourth sub-wireless transmission modules reduces the cost of electronic device accessories while ensuring the image projection effect meets requirements. Simultaneously, because multiple fourth sub-wireless transmission modules have different transmission channels with the electronic device, the hot-swap signal and auxiliary signal can be transmitted through different channels, avoiding mutual interference and improving the reliability of image transmission.

[0110] In one embodiment, such as Figure 10 As shown, there is one fourth sub-wireless transmission module 312. The electronic device accessory also includes a second signal processing module 33, which is electrically connected between the fourth sub-wireless transmission module 312 and the interface 32. The second signal processing module 33 is electrically connected to the fourth sub-wireless transmission module 312 via a fifth signal line. The second signal processing module 33 is electrically connected to the interface 32 via a sixth, seventh, and eighth signal line.

[0111] In this embodiment, by setting a second signal processing module to merge and recover signals, only a fourth sub-wireless transmission module is needed for signal transmission, thereby reducing the complexity of the electronic device accessory structure.

[0112] For example, to prevent the third sub-wireless transmission module 311 and the fourth sub-wireless transmission module 312 from interfering with each other and failing to transmit signals normally, the distance between the multiple third sub-wireless transmission modules 311 and the distance between the third sub-wireless transmission module 311 and the fourth sub-wireless transmission module 312 need to meet the requirements of a preset spacing.

[0113] For example, the second signal processing module 33 is used to combine the auxiliary signal and hot-plug signal output by the display device 70 into a second signal and transmit it to the fourth sub-wireless transmission module 312, and to restore a first signal transmitted by the electronic device 400 through the fourth sub-wireless transmission module 312 into an auxiliary signal and a hot-plug signal and transmit it to the display device 70.

[0114] In one embodiment, the second wireless transmission module 31 transmits wireless signals to the electronic device 400 via millimeter-wave communication.

[0115] In this embodiment, because the signal transmission speed is fast and the transmission distance is short under millimeter wave communication, the second wireless transmission module and electronic device can transmit a large number of signals in a short time and prevent wireless connection with the wrong electronic device, thereby improving the efficiency and reliability of wireless transmission.

[0116] In one embodiment, interface 32 is a DP interface.

[0117] In this embodiment, since the DP interface supports high resolution and high refresh rate, transmitting images via the DP interface improves the image projection effect. Furthermore, because the DP interface eliminates the need for power cables, grounding wires, and other wiring, the wiring in electronic device accessories is simplified, thereby reducing the complexity of the electronic device accessory structure.

[0118] In one embodiment, interface 32 is an HDMI interface.

[0119] In this embodiment, since the HDMI interface is widely used, transmitting images through the HDMI interface improves the versatility of electronic device accessories.

[0120] In one embodiment, such as Figure 11 As shown, the electronic device accessory 30 also includes a second housing 34 and a second adsorption part. A second wireless transmission module 31 is disposed within the second housing 34. The second adsorption part is disposed within the second housing 34 and is used to adsorb the electronic device 400.

[0121] In this embodiment, to facilitate matching between the electronic device and its accessory, a second adsorption part is provided within the second housing of the accessory to match the adsorbed electronic device. By providing a second adsorption part within the accessory to adsorb the electronic device, matching only occurs after adsorption, thus avoiding mismatch and improving the reliability of the accessory. Furthermore, since millimeter-wave communication has a short range, adsorption-based matching allows the accessory to wirelessly transmit images within an effective distance, further enhancing its reliability. Moreover, when the user needs wireless image transmission between the electronic device and its accessory, they only need to place the electronic device on the accessory, reducing the complexity of signal transmission.

[0122] For example, the surface of the second housing 34 is also provided with an interface 32.

[0123] In one embodiment, the second adsorption unit includes a third magnetic adsorption unit 351 and a fourth magnetic adsorption unit 352. The second wireless transmission module 31 is disposed between the third magnetic adsorption unit 351 and the fourth magnetic adsorption unit 352.

[0124] In this embodiment, since only two magnetic units are needed to attach the electronic device, the second attachment portion occupies less space in the electronic device accessory, thereby reducing the complexity of the accessory structure. Simultaneously, because the second wireless transmission circuit is positioned between the two magnetic units, the second and first wireless transmission modules can be aligned for wireless signal transmission after the electronic device is attached, thus improving the reliability of the electronic device accessory.

[0125] For example, interface 32 is disposed on one side of the second housing 34.

[0126] For example, the polarities of the third magnetic unit 351 and the fourth magnetic unit 352 may be the same or different. Specifically, the polarities of the third magnetic unit 351 and the first magnetic unit 61 are opposite, and the polarities of the fourth magnetic unit 352 and the second magnetic unit 62 are opposite.

[0127] For example, when the first adsorption part and the second adsorption part are adsorbed, the plurality of first sub-wireless transmission modules 21 of the electronic device 400 are respectively matched with the plurality of third sub-wireless transmission modules 311 of the electronic device accessory 30, and the second sub-wireless transmission module 22 of the electronic device 400 is matched with the fourth sub-wireless transmission module 312 of the electronic device accessory 30. That is, each first sub-wireless transmission module 21 is correspondingly set with a matched third sub-wireless transmission module 311, and each second sub-wireless transmission module 22 is correspondingly set with a matched fourth sub-wireless transmission module 312. The first adsorption part and the second adsorption part are used to reliably match the first sub-wireless transmission module 21 with the third sub-wireless transmission module 311 and the second sub-wireless transmission module 22 with the fourth sub-wireless transmission module 312.

[0128] For example, even when the number of the first sub-wireless transmission modules 21 of the electronic device 400 differs from the number of the third sub-wireless transmission modules 311 of the electronic device accessory 30, the electronic device 400 can still project images onto the display device 70 via the electronic device accessory 30. When the electronic device 400 has four first sub-wireless transmission modules 21 and the electronic device accessory 30 has two third sub-wireless transmission modules 311, the electronic device 400 can project images at a maximum resolution of 2K via the electronic device accessory 30. Similarly, when the electronic device 400 has two first sub-wireless transmission modules 21 and the electronic device accessory 30 has four third sub-wireless transmission modules 311, the electronic device 400 can also project images at a maximum resolution of 2K via the electronic device accessory 30.

[0129] An exemplary embodiment of this disclosure provides an electronic device accessory, such as... Figure 12 As shown, the electronic device accessory 30 includes an interface 32, a third sub-wireless transmission module 311, a fourth sub-wireless transmission module 312, a second signal processing module 33, a second housing 34, a third magnetic unit 351, and a fourth magnetic unit 352. There are four third sub-wireless transmission modules 311. The interface 32, the third sub-wireless transmission module 311, the fourth sub-wireless transmission module 312, the second signal processing module 33, the third magnetic unit 351, and the fourth magnetic unit 352 are all disposed within the second housing 34. The interface 32 is electrically connected to the first ends of the four third sub-wireless transmission modules 311, the second signal processing module 33, and the display device 70. The second end of the second signal processing module 33 is electrically connected to the fourth sub-wireless transmission module 312. The third sub-wireless transmission modules 311 and 312 are both disposed between the third magnetic unit 351 and the fourth magnetic unit 352.

[0130] For example, such as Figure 13As shown, the electronic device 400 and the electronic device accessory 30 transmit the first auxiliary signal AUX+, the second auxiliary signal AUX-, and the hot-plug signal HDP through the second sub-wireless transmission module 22 and the fourth sub-wireless transmission module 312. The electronic device 400 transmits four video signals to the four third sub-wireless transmission modules 311 through the four first sub-wireless transmission modules 21, respectively. The video signals are transmitted through the first transmission channel Lane1, the second transmission channel Lane2, the third transmission channel Lane3, and the fourth transmission channel Lane4, respectively, so that the display device 70 can project images at a maximum resolution of 4K.

Each front-facing camera module and rear-facing camera module may be a fixed optical lens system or have focal length and optical zoom capabilities.

[0136] Audio component 410 is configured to output and / or input audio signals.

The received audio signals may be further stored in memory 404 or transmitted via communication component 416. In some embodiments, audio component 410 also includes a speaker for outputting audio signals.

[0137] I / O interface 412 provides an interface between processing component 402 and peripheral interface modules, such as keyboards, click wheels, buttons, etc. These buttons may include, but are not limited to, home buttons, volume buttons, power buttons, and lock buttons.
