[0024] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0025] Figure 1 This is an example diagram of a scenario to which the embodiments of the present application can be applied. Figure 1 As shown, the scene 100 may include an electronic device 110 and an electronic device 120. The electronic device 110 and the electronic device 120 may communicate with each other.

[0026] The electronic device 110 may be an electronic device with a short-distance communication function. The short-distance communication function may include, for example, one or more of the following: Bluetooth, Wi-Fi, Zifeng, etc. In addition to the short-distance communication function, the electronic device 110 may also have an audio codec function. For example, the electronic device 110 may use a microphone (MIC) to collect an audio signal and send the audio signal outward through its antenna. For another example, the electronic device 110 may receive an externally transmitted audio signal through its antenna, thereby playing the audio signal through a speaker.

[0027] The electronic device 110 may be, for example, a handheld intelligent terminal, such as a smart phone ( Figure 1 The electronic device 110 is described by taking a smart phone as an example), a tablet computer, a virtual reality (VR) device, etc. Alternatively, the electronic device 110 may also be a wearable device, such as a smart watch, a smart bracelet, etc.

[0028] The electronic device 120 may be an electronic device with a short-distance communication function. The short-distance communication function may include, for example, one or more of the following: Bluetooth, Wi-Fi, Zifeng, etc. In addition to the short-distance communication function, the electronic device 120 may also have an audio codec function. For example, the electronic device 120 may collect an audio signal using a microphone and send the audio signal outward through its antenna. For another example, the electronic device 120 may receive an externally transmitted audio signal through its antenna, thereby playing the audio signal through a speaker.

[0029] The electronic device 120 may be, for example, a wearable device. The wearable device may be, for example, a wireless headset (such as a wireless Bluetooth headset, Figure 1 The electronic device 120 is taken as a wireless headset for example, a smart watch, a smart bracelet, a virtual reality device, etc. Alternatively, in some embodiments, the electronic device 120 may also be a handheld smart terminal, such as a mobile phone, a tablet computer, etc.

[0030] In scenario 100, the user may wish to perform stable data transmission between electronic device 110 and electronic device 120. For example, the user may use a mobile phone to transmit audio data to a wireless headset so that the user wearing the wireless headset can enjoy music quietly. However, in the process of the above audio data transmission, it is easy to be blocked by the human body, which may lead to the problem of low data transmission efficiency. Figure 2 Provide detailed distance description.

[0031] Figure 2 is another example diagram of a scenario to which the embodiments of the present application can be applied. Figure 2 As shown, whether the user holds the electronic device 110 in his hand or puts it on the table or in his trouser pocket, the electronic device 110 (such as a smart phone, Figure 2 Taking the electronic device 110 as a smart phone as an example, the electronic device 120 (such as a wireless Bluetooth headset, Figure 2 Taking the electronic device 120 as a wireless headset as an example for illustration), it will be blocked by the body, resulting in a significant reduction in the signal, which will in turn make it impossible to transmit and play high-definition audio sources or limit the playback of high-definition audio sources, resulting in a poor user experience.

[0032] In order to solve the above problems, the embodiment of the present application provides a data transmission method, which can establish a human body communication connection between a first electronic device (such as a smart phone) and a second electronic device (such as a wireless headset) through the user's body; in response to the signal quality of the human body communication connection being greater than a preset threshold, the first electronic device can send a target data signal to the second electronic device through the human body communication connection. In other words, the scheme in the embodiment of the present application can realize data transmission between the first electronic device and the second electronic device by means of human body communication based on the signal strength of human body communication, so as to effectively reduce the blocking effect of the user's body on the signal, thereby helping to improve the communication quality and user experience.

[0033] Combined with the following Figure 3 The data transmission method in the embodiment of the present application is introduced in detail. Figure 3 The method shown can be performed by a first electronic device (such as the electronic device 110 mentioned above) and a second electronic device (such as the electronic device 120 mentioned above). As an example, the first electronic device can be a smart phone, and the second electronic device can be a wireless Bluetooth headset.

[0034] It should be noted that the data signal transmission between the first electronic device and the second electronic device is mutual. If the first electronic device sends a data signal to the second electronic device, the second electronic device will receive the data signal sent from the first electronic device, and vice versa.

[0035] See also Figure 3 In step S320, a human body communication connection is established with the second electronic device through the user's body.

[0036] In some embodiments, before the first electronic device establishes a human body communication connection with the second electronic device through the user's body, it also includes detecting whether the first electronic device and the second electronic device support the human body communication connection.

[0037] In some embodiments, after determining that both the first electronic device and the second electronic device support the human body communication function, the method may further include turning on the human body communication function of the first electronic device and the second electronic device.

[0038] The embodiments of the present application do not specifically limit the method of detecting whether the first electronic device and the second electronic device support human body communication. For example, the device manuals of the first electronic device and the second electronic device can be checked to determine whether the human body communication function is supported. For another example, actual measurements can be performed: when the electronic device is close to the user's body, it can be detected whether data signals can be sent and received through the human body.

[0039] Human body communication (HBC) is also called intra-body communication (IBC). It can be understood as a short-distance wireless communication method. Human body communication can refer to a communication method that uses the human body as a signal (information) channel to transmit communication signals. Its feasibility is based on the electrical conductivity of human biological tissue. (This article will be combined with Figure 4 The principle of human body communication is explained with examples, see Figure 4 The description of the part will not be elaborated here).

[0040] In step S340, in response to the signal quality of the human body communication connection being greater than a preset threshold, a target data signal is sent to the second electronic device through the human body communication connection.

[0041] The target data signal may be referred to as target data for short. The target data signal may be, for example, video data or audio data, etc., and the present application does not impose any specific limitation on this.

[0042] The preset threshold of the signal quality of the human body communication connection can be set according to demand, and this application does not impose any specific restrictions on this.

[0043] In some embodiments, a first wireless communication connection can be established between a first electronic device and a second electronic device; in response to the signal quality of the human body communication connection between the first electronic device and the second electronic device being less than or equal to a preset threshold, a target data signal can be sent to the second electronic device via the first wireless communication connection, and accordingly, the second electronic device can receive the target data signal sent by the first electronic device via the first wireless communication connection.

[0044] In some embodiments, a first wireless communication connection can be established between the first electronic device and the second electronic device before the signal quality of the human body communication connection between the first electronic device and the second electronic device is less than or equal to a preset threshold; or a first wireless communication connection can be established between the first electronic device and the second electronic device after the signal quality of the human body communication connection between the first electronic device and the second electronic device is less than or equal to a preset threshold. The present application does not impose any specific restrictions on this.

[0045] In the embodiment of the present application, the communication method between the first electronic device and the second electronic device is selected based on the signal quality of the human body communication. If the signal quality of the human body communication is greater than a preset threshold, the human body communication method can be used to achieve data transmission between the first electronic device and the second electronic device, so as to effectively reduce the blocking effect of the user's body on the signal, thereby helping to improve the communication quality and user experience. Furthermore, if the signal quality of the human body communication is less than or equal to the preset threshold, the first wireless communication method can be used to achieve data transmission between the first electronic device and the second electronic device, so as to take into account the communication quality and communication stability between the first electronic device and the second electronic device, which helps to better improve the user experience.

[0046] In some embodiments, after establishing a human body communication connection with the second electronic device through the user's body, the method may further include: obtaining a signal quality of the human body communication connection.

[0047] The embodiments of the present application do not specifically limit the method for obtaining the signal quality of the human body communication connection. For example, the signal quality of the human body communication connection can be determined by detecting the packet loss rate of the human body communication connection. For another example, in some embodiments, in order to more conveniently obtain the signal quality of the human body communication connection, the signal quality of the human body communication can be determined based on the distance between the first electronic device and the user's body and / or the distance between the second electronic device and the user's body.

[0048] It is understandable that the human body communication connection mainly uses the human body as a signal channel to transmit communication signals. If the first electronic device or the second electronic device is far away from the user's body, the signal quality of the human body communication connection will be relatively poor.

[0049] In some embodiments, a mapping relationship table between the distance between the first electronic device and the user's body and / or the distance between the second electronic device and the user's body and the signal quality of human body communication can be pre-established and stored. Then, the corresponding signal quality of human body communication can be determined by looking up the table according to the distance between the first electronic device and the user's body and / or the distance between the second electronic device and the user's body.

[0050] In some embodiments, the first electronic device and the second electronic device may include a distance sensor for detecting the distance from the user's body.

[0051] In some embodiments, the first electronic device can detect and obtain the distance between the first electronic device and the user's body and / or the distance between the second electronic device and the user's body; the second electronic device can also detect and obtain the distance between the first electronic device and the user's body and / or the distance between the second electronic device and the user's body, and transmit the distance data to the first electronic device. Of course, the first electronic device can also obtain the distance between the first electronic device and the user's body, and the second electronic device can obtain the distance between the second electronic device and the user's body, and then the second electronic device can transmit the distance data between the second electronic device and the user's body detected by it to the first electronic device.

[0052] It can be understood that if the distance between the first electronic device and the user's body and / or the distance between the second electronic device and the user's body is greater than a preset distance threshold, it can be determined that the signal quality of the human body communication connection does not meet the requirements.

[0053] The first wireless communication may be Bluetooth, Wireless Fidelity, or Zifeng, etc., and this application does not impose any specific limitation on this.

[0054] In some embodiments, in order to reduce the cost and volume of the electronic device, the human body communication connection and the first wireless communication connection can share the same antenna for data transmission. That is, the human body communication in the first electronic device and the first wireless communication can share the antenna for data transmission and reception, and / or the human body communication in the second electronic device and the first wireless communication can share the antenna for data transmission and reception.

[0055] In some embodiments, if the human body communication connection and the first wireless communication connection can share the same antenna for data transmission, the human body communication and the first wireless communication can be performed alternately; that is, data transmission using human body communication and data communication using the first wireless communication can be performed alternately.

[0056] In some embodiments, the second electronic device includes a first sub-device and a second sub-device. If the signal quality between the first sub-device and the first electronic device is higher than the signal quality between the second sub-device and the first electronic device, the first sub-device can be used to receive a target data signal sent from the first electronic device; then, based on the human body communication connection between the first sub-device and the second sub-device, the first sub-device can be used to synchronize the target data signal to the second sub-device.

[0057] In some embodiments, if the signal quality of the human body communication connection between the first sub-device and the first electronic device is higher than the signal quality of the human body communication connection between the second sub-device and the first electronic device, the first sub-device can be used to receive the target data signal sent from the first electronic device through the human body communication connection (the human body communication connection between the first sub-device and the first electronic device); then, based on the human body communication connection between the first sub-device and the second sub-device, the first sub-device can be used to synchronize the target data signal to the second sub-device.

[0058] In some embodiments, if the signal quality of the wireless communication connection (e.g., a Bluetooth connection) between the first sub-device and the first electronic device is higher than the signal quality of the wireless communication connection (e.g., a Bluetooth connection) between the second sub-device and the first electronic device, the first sub-device can be used to receive a target data signal sent from the first electronic device via the wireless communication connection (e.g., a Bluetooth connection); and then, based on the human body communication connection between the first sub-device and the second sub-device, the first sub-device can be used to synchronize the target data signal to the second sub-device.

[0059] In some embodiments, before synchronizing the target data signal to the second sub-device using the first sub-device, it also includes establishing a human body communication connection between the first sub-device and the second sub-device.

[0060] according to Figure 2 It can be seen from the description of some contents that when the first electronic device is located on one side of the user's body, the signal quality of the communication between the first electronic device and the first sub-device may be different from the signal quality of the communication between the first electronic device and the second sub-device. In the embodiment of the present application, the first sub-device with better communication quality with the first electronic device is used to receive the target data signal sent by the first electronic device, and then the target data signal is synchronized to the second sub-device, so as to ensure the communication quality between the first sub-device and the second sub-device.

[0061] It is understandable that the second electronic device may include multiple sub-devices, and the multiple sub-devices may include a first sub-device and a second sub-device. For the convenience of description, this application is described by taking the first sub-device and the second sub-device as examples. The first sub-device may refer to a sub-device with the best communication quality with the first electronic device among the multiple sub-devices, and the second sub-device may refer to any sub-device among the multiple sub-devices except the first sub-device.

[0062] The following takes the first electronic device as an example. Figure 4 The human body communication technology in the embodiments of the present application is illustrated in more detail.

[0063] See also Figure 4The first electronic device may include a human body communication chip (not shown in the figure) and a human body communication antenna (also referred to as an electrode), and the human body communication chip is connected to the human body communication antenna. In some embodiments, the front of the first electronic device may be a display screen, and the human body communication antenna may be arranged on the back of the first electronic device. When the user holds the first electronic device or the user approaches the human body communication antenna, capacitive coupling is performed between the human body communication antenna and the user's body, thereby forming an equivalent capacitor. Based on the equivalent capacitor, the first electronic device can input a weak electrical signal into the user's body through the human body communication antenna, thereby realizing information transmission.

[0064] It is understandable that the second electronic device also includes a human body communication chip and a human body communication antenna. The human body communication antenna of the second electronic device also forms an equivalent capacitance path with the user's body, so that a human body communication loop can be formed between the human body communication antenna of the first electronic device, the user's body and the human body communication antenna of the second electronic device to transmit the target data signal.

[0065] In some embodiments, in order to accurately measure the distance between the human body communication antenna and the human body, the distance sensor in the first electronic device and the second electronic device can be correspondingly set on their human body communication antennas. The distance sensor can be used to detect the distance between the human body communication antenna of the first electronic device or the human body communication antenna of the second electronic device and the user's body.

[0066] In some embodiments, the signal frequency of human body communication may be 10 MHz to 20 MHz.

[0067] In some embodiments, if the first wireless communication is Bluetooth communication, the first wireless communication usually operates in the 2.4G or 5G frequency band. It is understandable that through reasonable filtering control, the coexistence interference problem between the human body communication and the first wireless communication can be effectively avoided.

[0068] It should be noted that the first electronic device and the second electronic device in the embodiment of the present application can be any of the electronic devices mentioned above. For example, the first electronic device can be a smart phone, and the second electronic device can be a Bluetooth headset; for another example, the first electronic device can be a smart phone, and the second electronic device can be a smart bracelet or a smart watch. For another example, the first electronic device can be a head device of a VR device, and the second electronic device can be a hand device (such as a handle) of the VR device. This application does not make specific restrictions on this.

[0069] In order to deepen the understanding of the above data transmission method, the following takes the first electronic device as a smart phone (can be referred to as a mobile phone) and the second electronic device as a wireless Bluetooth headset (can be referred to as a Bluetooth headset) as an example. Figure 5 and Figure 6The above data transmission method is described in more detail with examples.

[0070] Figure 5 Another data transmission method is shown. Figure 5 As shown, it may specifically include steps: S501 to S508.

[0071] In step S501: determine whether the mobile phone and the Bluetooth headset support human body communication connection, if so, jump to step S502, otherwise, jump to step S506.

[0072] In step S502: a human body communication connection is established between the mobile phone and the Bluetooth headset.

[0073] It is understandable that before establishing a human body communication connection between the mobile phone and the Bluetooth headset, the human body communication function of the mobile phone and the Bluetooth headset may be turned on. For example, after the Bluetooth headset recognizes the box opening signal, the human body communication function of the Bluetooth headset may be automatically turned on.

[0074] In step S503: determine whether the signal quality of human body communication is greater than a preset threshold, if it is greater than the preset threshold, jump to step S504, otherwise, jump to step S506.

[0075] In step S504: the Bluetooth headset receives the audio data sent by the mobile phone through the human body communication connection.

[0076] In step S505: the audio data is played using a Bluetooth headset.

[0077] In step S506: a Bluetooth connection is established between the mobile phone and the Bluetooth headset.

[0078] In step S507: the Bluetooth headset receives the audio data sent by the mobile phone via the Bluetooth connection. It is understandable that, in order to save energy consumption, after selecting Bluetooth for data transmission, the human body communication connection can be disconnected.

[0079] In step S508: the audio data is played using a Bluetooth headset.

[0080] According to the above Figure 5 From the description in the content, it can be seen that the use of human body communication connection and Bluetooth communication connection in coordination with each other can better improve the data transmission quality between the wireless Bluetooth headset and the mobile phone, which helps to improve the user experience.

[0081] Figure 6 Another data transmission method is shown. Figure 6 As shown, it may specifically include steps: S601 to S612.

[0082] In step S601: determine whether the mobile phone and the Bluetooth headset support human body communication connection. If not, jump to step S602; otherwise, jump to step S610.

[0083] In step S602: a Bluetooth connection is established between the mobile phone and the Bluetooth headset.

[0084] It is understandable that establishing a Bluetooth connection between a mobile phone and a Bluetooth headset may include: establishing a Bluetooth connection between the mobile phone and a left-ear Bluetooth headset (which may be referred to as the left-ear headset), and at the same time, establishing a Bluetooth connection between the mobile phone and a right-ear Bluetooth headset (which may be referred to as the right-ear headset).

[0085] In step S603: determine whether the signal quality of the left earphone is higher than that of the right earphone. If the signal quality of the left ear Bluetooth headset is higher than that of the right ear Bluetooth headset, jump to step S604, otherwise jump to step S607.

[0086] In step S604: the left ear Bluetooth headset is used to receive audio data sent by the mobile phone.

[0087] In step S605: the audio data received by the left-ear Bluetooth headset is synchronized to the right-ear Bluetooth headset via the human body communication connection (the human body communication connection between the left-ear Bluetooth headset and the right-ear Bluetooth headset). It should be understood that before the audio data received by the left-ear Bluetooth headset is synchronized to the right-ear Bluetooth headset via the human body communication connection, it also includes: establishing a human body communication connection between the left-ear Bluetooth headset and the right-ear Bluetooth headset.

[0088] In step S606: the audio data is played using the left-ear Bluetooth headset and the right-ear Bluetooth headset.

[0089] In step S607: the right ear Bluetooth headset is used to receive audio data sent by the mobile phone.

[0090] In step S608: the audio data received by the right-ear Bluetooth headset is synchronized to the left-ear Bluetooth headset via the human body communication connection (the human body communication connection between the left-ear Bluetooth headset and the right-ear Bluetooth headset). It should be understood that before the audio data received by the right-ear Bluetooth headset is synchronized to the left-ear Bluetooth headset via the human body communication connection, it also includes: establishing a human body communication connection between the left-ear Bluetooth headset and the right-ear Bluetooth headset.

[0091] In step S609: the audio data is played using the left-ear Bluetooth headset and the right-ear Bluetooth headset.

[0092] In step S610: a human body communication connection is established between the mobile phone and the Bluetooth headset.

[0093] It is understandable that when the mobile phone actively initiates a human body communication connection with the Bluetooth headset, after the human body communication is successfully established, the Bluetooth headset can also send an ACK message to the mobile phone.

[0094] It is understandable that before establishing a human body communication connection between the mobile phone and the Bluetooth headset, the human body communication function of the mobile phone and the Bluetooth headset may also be turned on.

[0095] In step S611: the Bluetooth headset receives the audio data sent by the mobile phone through the human body communication connection.

[0096] In step S612: the audio data is played using a Bluetooth headset.

[0097] According to the above Figure 6 From the description in the content, it can be seen that when the mobile phone is on one side of the body and the user's body blocks the signal of the earphone on the other side, by combining the Bluetooth communication connection and the human body communication connection, the signal attenuation caused by body blocking can be effectively avoided, thereby improving the audio data transmission quality and user experience.

[0098] Combination of the above Figures 1 to 6 The method embodiment of the present application is described in detail. Figures 7 to 11 The device embodiment of the present application is described in detail. It should be understood that the description of the method embodiment corresponds to the description of the device embodiment, so the parts not described in detail can refer to the previous method embodiment.

The electronic device may be, for example, the first electronic device mentioned above. The electronic device 700 includes: a first human body communication chip 710 and a first processor 720.

[0100] The first human body communication chip 710 is used to establish a human body communication connection with the second electronic device through the user's body.

[0101] The first processor 720 is connected to the first human body communication chip, and is used for sending a target data signal to the second electronic device through the first human body communication chip in response to a signal quality of the human body communication connection being greater than a preset threshold.

[0102] Optionally, the electronic device 700 also includes: a first wireless communication chip 730, used to establish a first wireless communication connection with the second electronic device in response to the signal quality of the human body communication connection being less than or equal to the preset threshold; the first processor 720 is also used to send the target data signal to the second electronic device through the first wireless communication chip.

[0106] In some embodiments, the first processor 720 may be a general-purpose processor or a special-purpose processor. For example, the processor may be a central processing unit (CPU). Alternatively, the processor may also be other general-purpose processors, digital signal processors (DSP), application specific integrated circuits (ASIC), field programmable gate arrays (FPGA) or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, etc. A general-purpose processor may be a microprocessor or the processor may also be any conventional processor, etc.
