[0047] Various exemplary embodiments of the present specification will now be described in detail with reference to the accompanying drawings.

[0048] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the embodiments of the present specification and its application or uses.

[0049] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0050] In one embodiment of the present invention, a data transmission method is provided. The method is implemented by a speaker provided with a first wireless charging device. Figure 1 As shown, the data transmission method of this embodiment may include the following steps S110 to S150.

[0051] Step S110, in response to sensing that the terminal device is placed in the setting position of the first wireless charging device, using the first wireless charging device to send a request for obtaining a Bluetooth address to the terminal device.

[0052] The terminal device is a mobile phone, tablet computer or wearable device.

[0053] In one embodiment, before executing step S110, the method further includes: using the first wireless charging device to transmit Analog Ping and Digital Ping to complete foreign object detection. This achieves the placement detection of the terminal device. Transmitting Analog Ping and Digital Ping specifically includes the following stages: Selection, Ping (network packet exploration), Identification & Configuration, and Power Transfer.

[0054] In one embodiment, the first wireless charging device includes a first wireless charging chip and a first wireless charging coil, the second wireless charging device includes a second wireless charging chip and a second wireless charging coil, and the second wireless charging chip stores a Bluetooth address of the terminal device.

[0055] In this embodiment, step S110 specifically includes: using the first wireless charging chip, through the coupling of the first wireless charging coil and the second wireless charging coil, sending the acquisition request of the Bluetooth address to the second wireless charging chip. The acquisition request of the Bluetooth address is a modulated signal obtained after modulation by the first wireless charging chip. The modulation technology is FSK (Frequency Shift Keying) technology. The modulated signal is sent to the RX end of the second wireless charging chip through the TX end of the first wireless charging chip and the coupling of the first wireless charging coil and the second wireless charging coil. After receiving the modulated signal, the second wireless charging chip demodulates the modulated signal to obtain the acquisition request of the Bluetooth address. The second wireless charging chip modulates the Bluetooth address of the terminal device to obtain a modulated signal, and uses its TX end to send the modulated signal to the RX end of the first wireless charging chip through the coupling of the second wireless charging coil and the first wireless charging coil. It should be noted that when performing the above-mentioned foreign object detection, the first wireless charging chip informs the second wireless charging chip of the FSK parameters.

[0056] Step S120, receiving the Bluetooth address of the terminal device returned by the second wireless charging device, wherein the second wireless charging device is set in the terminal device.

[0057] In one embodiment, the Bluetooth address of the terminal device sent by the second wireless charging chip is received through the coupling of the second wireless charging coil and the first wireless charging coil. Specifically, the Bluetooth address of the terminal device is a modulated signal obtained after modulation by the second wireless charging chip. The modulated signal is sent to the RX end of the first wireless charging chip through the TX end of the second wireless charging chip and the coupling of the second wireless charging coil and the first wireless charging coil. After receiving the modulated signal, the first wireless charging chip demodulates the modulated signal to obtain the Bluetooth address of the terminal device.

[0058] Step S130, obtaining a Bluetooth address pairing list, wherein the Bluetooth address pairing list includes Bluetooth addresses that have been successfully paired in the past.

[0059] Step S140: When the Bluetooth address pairing list includes the Bluetooth address of the terminal device, establish a Bluetooth connection with the terminal device.

[0060] Specifically, the Bluetooth address of the terminal device is compared with each Bluetooth address in the Bluetooth address pairing list to obtain a comparison result. If the comparison result shows that the Bluetooth address of the terminal device is consistent with a Bluetooth address in the Bluetooth address pairing list, it is determined that the terminal device and the speaker have completed Bluetooth pairing before. At this time, the speaker automatically establishes a Bluetooth connection with the terminal device to ensure the security of the Bluetooth connection.

[0061] In one embodiment, the method further includes: when the Bluetooth address pairing list does not include the Bluetooth address of the terminal device, using the first wireless charging device to send a Bluetooth pairing request to the terminal device, so that the Bluetooth pairing request is displayed on the display interface of the terminal device.

[0062] Specifically, the Bluetooth address of the terminal device is compared with each Bluetooth address in the Bluetooth address pairing list to obtain a comparison result. When the comparison result is that the Bluetooth address of the terminal device is inconsistent with each Bluetooth address in the Bluetooth address pairing list, it means that the terminal device and the speaker have not completed Bluetooth pairing before. At this time, the first wireless charging chip is used to send a Bluetooth pairing request to the second wireless charging chip through the coupling of the first wireless charging coil and the second wireless charging coil. The Bluetooth pairing request is a modulated signal obtained after modulation by the first wireless charging chip. The modulated signal is sent to the RX end of the second wireless charging chip through the TX end of the first wireless charging chip and the coupling of the first wireless charging coil and the second wireless charging coil. After receiving the modulated signal, the second wireless charging chip demodulates the modulated signal to obtain a Bluetooth pairing request. After receiving the Bluetooth pairing request, the terminal device displays the Bluetooth pairing request on the display interface. After the user triggers the Bluetooth pairing operation, the second wireless charging chip modulates the Bluetooth pairing determination instruction to obtain a modulated signal, and uses its TX end to send the modulated signal to the RX end of the first wireless charging chip through the coupling of the second wireless charging coil and the first wireless charging coil. The first wireless charging chip demodulates the modulated signal, obtains a confirmation instruction for Bluetooth pairing, and establishes a Bluetooth connection with the terminal device. After the user confirms the Bluetooth pairing, the Bluetooth connection between the speaker and the terminal device is executed, which can ensure the security of the Bluetooth connection.

[0063] Step S150: performing data transmission with the terminal device based on the Bluetooth connection established with the terminal device.

[0064] In one embodiment, step S150 specifically includes: based on the Bluetooth connection established with the terminal device, obtaining the audio data currently played by the terminal device; playing the audio data currently played by the terminal device. In this way, the audio data currently played by the terminal device can be played through the speaker. Since the speaker has a higher speaker configuration than the terminal device, the sound quality can be improved, and a more delicate, full and realistic sound effect can be presented.

[0065] In one embodiment, the method further includes: determining the distance between the speaker and the person in the room; and adjusting the volume of the audio data played by the speaker according to the distance between the speaker and the person in the room. In this way, the playback volume of the speaker can be automatically adjusted to an appropriate volume according to the distance between the speaker and the user, thereby improving the user experience.

[0066] Specifically, the speaker stores the correspondence between the distance between the speaker and the person in the room and the speaker playback volume value. Using the distance between the speaker and the person in the room, the corresponding speaker playback volume value is searched from the correspondence between the distance between the speaker and the person in the room and the speaker playback volume value, and is used as the volume value of the speaker playing the current audio data.

[0067] In one embodiment, the speaker includes a millimeter wave radar. The method also includes: obtaining point cloud data collected by the millimeter wave radar; determining whether there is a person in the room based on the point cloud data collected by the millimeter wave radar. The millimeter wave radar emits electromagnetic waves and receives its reflected signals, which form point cloud data. Using a clustering algorithm, clustering processing is performed on the point cloud data collected by the millimeter wave radar to determine whether the category corresponding to the detected target object includes a person. Specifically, a clustering algorithm is used to cluster the point cloud data collected by the millimeter wave radar to determine the shape and size of the target object, and the category corresponding to the target object is determined based on the shape and size of the target object. When the category corresponding to the detected target object includes a person, it is determined that there is a person in the room. The category corresponding to the detected target object is a person and / or an object.

[0068] In this embodiment, when there is a person in the room, an operation of determining the distance between the speaker and the person in the room is performed.

[0069] In one embodiment, a millimeter wave radar is used to determine the distance between the speaker and the person in the room. Specifically, a signal is transmitted to the person in the room using the transmitting antenna of the millimeter wave radar. When the transmitted signal reaches the person in the room, it is reflected back. The reflected signal is received using the receiving antenna of the millimeter wave radar. The distance between the speaker and the person in the room is calculated based on the propagation speed of the signal and the time difference between the transmitted signal and the reflected signal. The millimeter wave radar includes multiple antennas and uses a multi-transmit and multi-receive method to determine the distance between the speaker and the person in the room.

[0070] In one embodiment, the speaker includes a camera. The method further includes: acquiring image data collected by the camera; and determining whether there is a person in the room according to the image data collected by the camera. The image data collected by the camera is input into an image processing model to determine whether there is a person in the image. If it is determined that there is a person in the image, it is determined that there is a person in the room.

[0071] In this embodiment, when there is a person in the room, an operation of determining the distance between the speaker and the person in the room is performed.

[0072] In one embodiment, the speaker includes an infrared camera. The infrared camera is used to determine the distance between the speaker and the person in the room.

[0073] The data transmission method provided by the present invention realizes automatic Bluetooth connection between the speaker and the terminal device on the one hand, and realizes interaction between the speaker and the terminal device based on the established Bluetooth connection on the other hand.

[0074] In one embodiment of the present invention, a data transmission method is provided. The method is implemented by a terminal device provided with a second wireless charging device. The terminal device is a mobile phone, a tablet computer or a wearable device.

[0075] according to Figure 2 As shown, the data transmission method of this embodiment may include the following steps S210 to S230.

[0076] Step S210: When the terminal device is placed in the setting position of the first wireless charging device in the speaker, a request for obtaining the Bluetooth address of the terminal device sent by the speaker is received by using the second wireless charging device.

[0077] In one embodiment, the first wireless charging device includes a first wireless charging chip and a first wireless charging coil, the second wireless charging device includes a second wireless charging chip and a second wireless charging coil, and the second wireless charging chip stores a Bluetooth address of the terminal device.

[0078] In this embodiment, the second wireless charging chip is used to receive a request for obtaining a Bluetooth address through coupling of the first wireless charging coil and the second wireless charging coil.

[0079] The request to obtain the Bluetooth address is a modulated signal obtained after modulation by the first wireless charging chip. The modulation technology is FSK (Frequency Shift Keying) technology. The modulated signal is sent to the RX end of the second wireless charging chip through the TX end of the first wireless charging chip and the coupling of the first wireless charging coil and the second wireless charging coil. After receiving the modulated signal, the second wireless charging chip demodulates the modulated signal to obtain the request to obtain the Bluetooth address.

[0080] Step S220, in response to the request for obtaining the Bluetooth address of the terminal device, the Bluetooth address of the terminal device is sent to the speaker using the second wireless charging device.

[0081] In one embodiment, the second wireless charging chip is used to send the Bluetooth address of the terminal device to the first wireless charging chip through the coupling of the second wireless charging coil and the first wireless charging coil. Specifically, the second wireless charging chip modulates the Bluetooth address of the terminal device to obtain a modulated signal, and uses its TX terminal to send the modulated signal to the RX terminal of the first wireless charging chip through the coupling of the second wireless charging coil and the first wireless charging coil.

[0082] Step S230, when the speaker establishes a connection with the terminal device based on the Bluetooth address of the terminal device, data is transmitted with the speaker.

[0083] In one embodiment, the speaker obtains a Bluetooth address pairing list, wherein the Bluetooth address pairing list includes Bluetooth addresses of historical successful pairings. When the Bluetooth address pairing list includes the Bluetooth address of the terminal device, a Bluetooth connection with the terminal device is established. When the Bluetooth address pairing list does not include the Bluetooth address of the terminal device, a Bluetooth pairing request sent by the first wireless charging device is received using a second wireless charging device, and the Bluetooth pairing request is displayed on a display interface.

[0084] Specifically, through the coupling of the first wireless charging coil and the second wireless charging coil, the second wireless charging chip is used to receive the Bluetooth pairing request. The Bluetooth pairing request is a modulated signal obtained after modulation by the first wireless charging chip. The modulated signal is sent to the RX end of the second wireless charging chip through the TX end of the first wireless charging chip and the coupling of the first wireless charging coil and the second wireless charging coil. After receiving the Bluetooth pairing request, the terminal device displays the Bluetooth pairing request on the display interface. After the user triggers the Bluetooth pairing operation, the second wireless charging chip modulates the Bluetooth pairing confirmation instruction to obtain a modulated signal, and uses its TX end to send the modulated signal to the RX end of the first wireless charging chip through the coupling of the second wireless charging coil and the first wireless charging coil. The first wireless charging chip demodulates the modulated signal, obtains the Bluetooth pairing confirmation instruction, and establishes a Bluetooth connection with the terminal device. After the user confirms the Bluetooth pairing, the Bluetooth connection between the speaker and the terminal device is executed to ensure the security of the Bluetooth connection.

[0085] In one embodiment, step S230 specifically includes: based on the Bluetooth connection established with the terminal device, sending the currently played audio data to the speaker, so that the speaker plays the currently played audio data. In this way, the audio data currently played by the terminal device can be played through the speaker. Since the speaker has a higher speaker configuration than the terminal device, the sound quality can be improved, and a more delicate, full and realistic sound effect can be presented.

[0086] The data transmission method provided by the present invention realizes automatic Bluetooth connection between the speaker and the terminal device on the one hand, and realizes interaction between the speaker and the terminal device based on the established Bluetooth connection on the other hand.
