Description

Technical Field

[0001] This application relates to the field of communications, and in particular to a data transmission method, apparatus, and headset. Background Technology

[0002] True wireless earbuds communicate wirelessly with paired electronic devices without traditional cables. If the left and right earbuds communicate wirelessly, they can be called true wireless earbuds. Currently, true wireless earbuds consist of one master earbud and one slave earbud, and the communication mode between them can be either relay mode or monitoring mode. However, regardless of the relay or monitoring mode, when the master earbud communicates with the slave earbud, the master earbud cannot simultaneously communicate with the paired electronic device (e.g., a mobile phone). This limits the actual bandwidth between the true wireless earbuds and the electronic device, thus affecting the connection performance and user experience. Summary of the Invention

[0060] The terminology used in the implementation section of this application is for the purpose of explaining specific embodiments of this application only, and is not intended to limit this application.

[0061] Wireless earbuds communicate wirelessly with their paired electronic devices without traditional cables. If the left and right ears of a wireless earbud also communicate wirelessly, it can be called a true wireless earbud.

[0062] Wireless headphones can include various types such as in-ear, semi-in-ear, and over-ear. True wireless headphones can be used in in-ear, semi-in-ear, and other types of headphones.

[0063] Currently, there are two main ways to implement communication between the left and right earbuds in true wireless earbuds: relay mode and monitoring mode. Typically, one earbud in a true wireless earbud is the master earbud and the other is the slave earbud; for example, the master earbud can be the left earbud and the slave earbud can be the right earbud.

[0064] The working principle of true wireless earbuds using the repeater mode is as follows: Figure 1As shown in the diagram, a Bluetooth connection is established between the main earpiece (e.g., the left earpiece) and an electronic device (e.g., a mobile phone), and data (e.g., music, voice, or other data packets) is transmitted between the main earpiece and the electronic device. Afterward, the main earpiece disconnects from the electronic device and establishes a Bluetooth connection with the slave earpiece (e.g., the right earpiece), forwarding the data to the slave earpiece.

[0065] The working principle of true wireless earbuds using monitoring mode is as follows: Figure 2 As shown in the diagram, a Bluetooth connection is established between the main earpiece (e.g., the left earpiece) and an electronic device (e.g., a mobile phone), and data (e.g., music, voice, or other data packets) is transmitted between the main earpiece and the electronic device. The main earpiece transmits the relevant parameters of the Bluetooth connection with the electronic device to the slave earpiece. The slave earpiece (e.g., the right earpiece) listens for and directly receives the Bluetooth signal from the electronic device; this reception does not depend on the forwarding of Bluetooth data from the main earpiece. If the slave earpiece does not detect a Bluetooth signal, the main earpiece disconnects from the electronic device and establishes a Bluetooth connection with the slave earpiece (e.g., the right earpiece), forwarding the data to the slave earpiece.

[0066] Regardless of whether it's a forwarding mode or a monitoring mode, true wireless earbuds cannot have Bluetooth connections between the main earbud and the slave earbud, or between the main earbud and an electronic device, existing simultaneously. This results in limited actual bandwidth between the true wireless earbuds and the electronic device, and between the main earbud and the slave earbud.

[0067] In forwarding mode, the main earphone and the electronic device, as well as the main earphone and the slave earphone, need to transmit complete and valid data through Bluetooth connections. The amount of data transmitted is large, the reliability of Bluetooth transmission is low, and the main earphone consumes a lot of power, resulting in short battery life for true wireless earphones.

[0068] In the aforementioned monitoring mode, the amount of data transmitted between the master and slave earphones is reduced by having the master earphone transmit the relevant parameters of the Bluetooth connection with the electronic device to the slave earphone, which then listens to and directly receives the Bluetooth signal from the smart device. However, there is still data that needs to be transmitted between the master and slave earphones, and there is still room for improvement in the data transmission speed between them compared to actual needs.

[0069] Moreover, with the increasing number of microphones and sensors in headphones, processing data from only one ear is insufficient to achieve optimal performance. It is necessary for the left and right ears to exchange audio, sensor, and other data for collaborative data processing. The data transmission rate requirement can reach over 30Mbps in order to improve the overall performance and experience of wireless headphones, especially true wireless headphones.

[0070] Therefore, this application proposes a data transmission method, apparatus, and earphone that can improve the actual bandwidth between the wireless earphone and the electronic device, as well as between the left and right earphones, thereby improving the user experience.

[0071] It should be noted that the data transmission method of this application can be applied to wireless headphones, but is not limited to true wireless headphones. The wireless headphones in the embodiments of this application can be in-ear, semi-in-ear, over-ear, etc., and the embodiments of this application do not limit them.

[0072] Figure 3 This is a schematic diagram illustrating a scenario to which the data transmission method of this application applies. For example... Figure 3 As shown, where,

[0073] The wireless earphone includes a main earphone 31 and a slave earphone 32. Optionally, the main earphone 31 can be the left earphone and the slave earphone 32 can be the right earphone; or, the main earphone 31 can be the right earphone and the slave earphone 32 can be the left earphone.

[0074] The main earphone 31 includes a first transmission module 311 and a first Bluetooth module 312, and the secondary earphone 32 includes a second transmission module 321 and a second Bluetooth module 322.

[0075] The first Bluetooth module 312 of the main earphone 31 can establish a Bluetooth connection with a paired electronic device for data transmission, and / or establish a Bluetooth connection with the second Bluetooth module 322 of the slave earphone for data transmission. The second Bluetooth module 322 of the slave earphone 32 can establish a Bluetooth connection with itself for data transmission, and / or establish a Bluetooth connection with a paired electronic device, and / or listen to Bluetooth signals sent by the electronic device, etc.

[0076] Data transmission can occur between the first transmission module 311 and the second transmission module 321, and this data transmission can be achieved through wireless transmission technology or wired transmission technology. Wireless transmission technology may include, but is not limited to: human body communication (HBC), wireless fidelity (WiFi), ultra-wideband (UWB), Bluetooth Super, or ultrasonic communication, etc. Wired transmission technology may include, but is not limited to: serializing / deserializing circuitry (SERDes), or Ethernet, etc.

[0077] In this embodiment, the first transmission module 311 and the second transmission module 321 can transmit data between the two earpieces. This data may include: service data that the main earpiece needs to send to the secondary earpiece, such as service data of the other user during a call, music data to be played, control and scheduling data in the service, and data collected by the earpieces (e.g., the left or right earpiece) (e.g., noise reduction data). In particular, the two earpieces can transmit their own collected data (e.g., noise reduction data), allowing each earpiece to obtain complete binaural data. After processing the binaural data, the user receives a better audio experience.

[0078] It should be noted that, since data between the master and slave earphones can be transmitted through the first and second transmission modules in this embodiment, the second Bluetooth module 322 in the slave earphone can be omitted in some embodiments. Currently, the master earphone and electronic device generally communicate via Bluetooth module. However, this embodiment does not limit the specific communication method between the master earphone and electronic device; that is, the first Bluetooth module in the master earphone can be replaced with a module that supports other wireless communication technologies. This embodiment does not impose any limitations.

[0112] The clock signal can be generated by the PLL module in the first processor.

[0113] Step 504: The first codec transmits the second data to the first data processing module sequentially through the sixth data interface and the second data interface.

[0114] The second data may include, but is not limited to: data used for headphone noise reduction (hereinafter referred to as noise reduction data), such as audio signals collected by the aforementioned single feed-forward (FF) microphone and / or single feed-back (FB) microphone.

[0115] There is no restriction on the execution order between steps 501 to 503 above.

[0116] Steps 501 to 503 are optional steps, and only at least one of the above steps can be executed each time; that is to say, as long as at least one of the above steps is executed, the data processing of the first data processing module in step 505 can be triggered.

[0117] Optionally, the second and sixth data interfaces mentioned above can be PDM interfaces. To reduce the data transmission pressure on the PDM interface and improve its data transmission efficiency, data with relatively high latency requirements in the first codec (e.g., active noise reduction data) can be sent to the first data processing module through the PDM interface; data with relatively low latency requirements in the first codec (e.g., noise reduction data during a call) can be transmitted to the first processor through the data interface between the first codec and the first processor, and then sent to the first data processing module by the first processor through the fifth and first data interfaces mentioned above.

[0118] Step 505: The first data processing module converts the received data into data frames according to the clock signal, generates a corresponding clock synchronization sequence for the data frames, and sends the generated data frames and their corresponding clock synchronization sequences to the first transceiver module.

[0119] In one possible implementation, the aforementioned data frame can be, for example... Figure 6 The structure is shown below. In this structure, the DS frame represents a data frame transmitted from the master earpiece to the slave earpiece, and the US frame represents a data frame transmitted from the slave earpiece to the master earpiece. It can be specified that DS frames and US frames can be transmitted simultaneously, or it can be specified that DS frames and US frames cannot be transmitted simultaneously.

[0120] A DS frame can specifically include: a frame synchronization sequence, a frame header, and frame data. The frame synchronization sequence is the start marker of the data frame; the frame header records relevant information about the frame data, such as address information and error control information; and the frame data carries the specific data to be transmitted. Optionally, each DS frame can transmit only one type of data, such as only I2S data or PDM data. Figure 6 As shown, if a DS frame transmits I2S data, the DS frame may include: a frame synchronization sequence, an I2S frame header, and I2S frame data. Hereinafter, this frame transmitting I2S data will be referred to as an I2S frame. If a DS frame transmits PDM data, the DS frame may include: a frame synchronization sequence, a PDM frame header, and PDM frame data. Hereinafter, this frame transmitting I2S data will be referred to as a PDM frame. The above data type classification is based on the interface through which the first data processing module receives data. Other data type classification methods may exist, which are not limited here.

[0121] For details on the implementation of US frames, please refer to the above description of DS frames; they will not be repeated here.

[0122] In this implementation, the first data processing module can dynamically allocate time slots for data frames to be transmitted based on the preset priority of the data to be transmitted (i.e., the received first data and / or second data and / or first control data). For example, PDM data can have a higher priority than I2S data; therefore, the first data processing module can prioritize allocating time slots for PDM frames. When bandwidth is insufficient, the first data processing module can drop I2S frames and retransmit them to ensure the transmission delay of PDM frames.

[0123] It should be noted that, under this data frame implementation method, if active noise cancellation (ANC) is enabled when transmitting I2S data, then the transmission of PDM data may be delayed by at least one frame.

[0124] In another possible implementation, the aforementioned data frame can be, for example... Figure 7 The structure shown is as follows. In this implementation, a data frame can transmit data of at least two data types.

[0125] Taking a data frame containing two data types as an example, a DS frame can specifically include: a frame synchronization sequence, a mixed frame header, first type data, and second type data. For example, the first type data can be I2S data (corresponding to...). Figure 7 The I2S bits in the structure shown), the second type of data can be PDM data (corresponding to Figure 7 (PDM bits in the structure shown).

[0126] For details on the implementation of US frames, please refer to the above description of DS frames; they will not be repeated here.

[0127] In this implementation, the first data processing module can allocate bits in the data frame according to the preset bandwidth ratio of each type of data (e.g., I2S data and PDM data). This implementation can guarantee the latency of each type of data.

[0128] The two implementation methods described above can also be combined. That is, for data of a certain type (such as active noise reduction data with high latency requirements in PDM data), the first implementation method is used to encapsulate it into a separate data frame, while for data of other types (such as I2S data with relatively low latency requirements and noise reduction data during calls in PDM data), the second implementation method is used to encapsulate it in the same data frame.

[0129] Step 506: The first transceiver module sends the clock synchronization sequence and data frames to the slave headset.

[0130] The first transceiver module can use wireless communication technologies, especially high-bandwidth wireless communication technologies, to send the aforementioned clock synchronization sequence and data frames, such as HBC, WiFi, or UWB.

[0131] In this method, the main earphone encapsulates the data to be transmitted to the slave earphone and transmits it to the slave earphone through a wireless communication method other than the original Bluetooth module in the main earphone. This eliminates the need to occupy the transmission resources of the Bluetooth module in the main earphone, increases the transmission bandwidth between the main earphone and the electronic device, and further increases the transmission bandwidth between the main earphone and the slave earphone. This can improve the business processing effect of the wireless earphone (such as the audio playback effect) and enhance the user experience.

[0132] exist Figure 4 The processing procedures performed from the earphone 42, as shown in the structure of the earphone 42, are as follows: Figure 8 As shown, it includes:

[0133] Step 801: Receive the clock synchronization sequence and data frame sent by the main headset from the second transceiver module of the headset, and send the clock synchronization sequence and data frame to the second data processing module.

[0134] Step 802: The second data processing module recovers the clock signal according to the clock synchronization sequence and obtains the corresponding data from the data frame according to the clock signal.

[0135] The data obtained from the data frame in this step may include: first data, and / or second data, and / or first control data.

[0136] Optionally, this step may also include: the second data processing module sending a clock signal to the PLL module of the second processor through the second clock interface and the fourth clock interface.

[0137] Optionally, the second data processing module may include a clock recovery submodule and a deframe submodule. The clock recovery submodule is used to recover the clock signal according to the clock synchronization sequence, and the deframe submodule is used to obtain the corresponding data from the data frame according to the clock signal.

[0138] Step 803: The second data processing module sends the first data to the second processor sequentially through the third data interface and the seventh data interface.

[0139] Step 804: The second data processing module sends the first control data to the second processor sequentially through the second control interface and the fourth control interface.

[0140] Step 805: The second data processing module sends the second data to the second codec sequentially through the fourth data interface and the eighth data interface.

[0141] There is no restriction on the execution order between steps 803 and 805 above.

[0142] Steps 803 to 805 above are optional steps. Whether each step is executed depends on the data obtained by the second data processing module from the data frame. For example, if only the first data is obtained, only step 803 is executed; if the first data and the first control data are obtained, then steps 803 and 804 are executed; and so on.

[0143] The second codec can perform noise reduction and other processing based on the audio signal in the second data.

[0144] Optionally, the aforementioned second and sixth data interfaces can be PDM interfaces. To reduce the data transmission pressure on the PDM interface and improve its data transmission efficiency, data with relatively high latency requirements (e.g., active noise cancellation data) in the received second data can be sent to the second codec via the PDM interface; data with relatively low latency requirements (e.g., noise cancellation data during a call) in the received second data can be transmitted to the first processor via the data interface between the second data processing module and the second processor, and then sent to the second codec by the second processor via the data interface between the second processor and the second codec.

[0145] In this method, the slave earphone can cooperate with the master earphone and use other devices besides the Bluetooth module, thus avoiding the occupation of the transmission resources of the Bluetooth module in the master earphone, increasing the transmission bandwidth between the master earphone and the electronic device, and increasing the transmission bandwidth between the master earphone and the slave earphone, thereby improving the service processing effect of the wireless earphone (such as audio playback effect) and enhancing the user experience.

[0146] Figure 9 This is a schematic diagram illustrating another embodiment of the data transmission method of this application. Figure 4 The main difference in the scenarios shown is that there are no data transmission interfaces between the first codec and the first transmission module, and between the second codec and the second transmission module; that is, no second data interface and a sixth data interface are provided. For example, if the second data interface is a PDM interface, and the first codec mode is an external or integrated codec that does not support the PDM interface, then the PDM interface of the first transmission module cannot connect to the codec.

[0147] In this scenario, Figure 5 Step 503 shown can be replaced by the following steps: the first codec sends the second data to the first processor through the data interface between the first codec and the first processor; the first processor transmits the second data to the first data processing module in sequence through the fifth data interface and the first data interface.

[0148] Correspondingly, Figure 8 Step 805 shown can be replaced by the following steps: the second data processing module sends the second data to the second processor in sequence through the third data interface and the seventh data interface, and the second processor sends the second data to the second codec.

[0149] Figure 10 This is a schematic diagram illustrating another embodiment of the data transmission method of this application. Figure 4 The main difference between the scenarios shown is that the first transceiver module and the second transceiver module transmit data via a wired connection, and the DS frame and the US frame are transmitted through the same wired link.

[0150] Figure 11 This is a schematic diagram illustrating another embodiment of the data transmission method of this application. Figure 10 The main difference in the illustrated scenario is that the first transceiver module is replaced by a first wired receiving module and a first wired transmitting module, and the second transceiver module is replaced by a second wired receiving module and a second wired transmitting module. Accordingly, the first wired transmitting module can be connected to the second wired receiving module for transmitting DS frames; the first wired receiving module can be connected to the second wired transmitting module for transmitting US frames. In other words, this embodiment has two wired links, one for transmitting DS frames and one for transmitting US frames.

[0151] In this scenario, Figure 5 The first transceiver module in the steps of the method shown can be replaced with a first wired transmission module. Figure 8 The second transceiver module in the steps of the method shown can be replaced with a second wired receiver module, which will not be elaborated here.

[0152] It should be noted that the above Figure 10 and Figure 11 In the scenario diagram shown, there may be no data transmission interface between the first codec and the first transmission module, or between the second codec and the second transmission module. For specific implementation structures and principles, please refer to [reference needed]. Figure 9 The corresponding explanations will not be repeated here.

[0153] It should be noted that the master earphone and slave earphone in the above embodiments can be interchanged. In this case, the slave earphone acts as the data sender and the master earphone acts as the data receiver. The specific implementation structure and processing flow can be referred to the above embodiments, and will not be repeated here.

[0154] It should be noted that the above embodiments take the inclusion of a second processor (e.g., a SOC) in the earphone as an example. In other embodiments provided in this application, the second processor may not be included in the earphone described above. The business processing logic in the main earphone and the earphone is completed by the first processor (e.g., a SOC) in the main earphone. In this case, the earphone may mainly include the second transmission module and the second codec mentioned above. The second codec can be connected to the earphone's speaker, microphone, noise-canceling microphone, etc. Optionally, the earphone may also include other devices such as sensors (e.g., gyroscopes), which can be directly connected to the second transmission module through a data interface. The following examples illustrate this:

[0155] For example, the above Figure 10 This can be extended to the scenario described above where the headphones do not include a second processor; see details below. Figure 12 In contrast Figure 10 The schematic diagram shows that no second processor is installed in the earphone. Accordingly, the second transmission module does not have a second control interface or a second clock interface. Devices such as sensors that were originally connected to the second processor are directly connected to the second data processing module in the second transmission module through the third data interface.

[0156] In this scenario, the second codec of the earphone can send the acquired noise reduction data to the first transmission module of the main earphone through the second transmission module, and then the first transmission module of the main earphone can send it to the first processor and / or the first codec for processing; the aforementioned sensors and other devices of the earphone can send their own operating parameters to the second transmission module through the data interface, and then the second transmission module can send them to the first transmission module of the main earphone. The first transmission module can send the aforementioned operating parameters to the first processor for processing.

[0157] The service data (e.g., audio data) processed by the first processor in the main earphone and / or the noise reduction data obtained by the first codec can be transmitted from the first transmission module to the second transmission module, and then sent by the second transmission module to the second codec for further processing (e.g., noise reduction processing of the audio data based on the noise reduction data, sending the audio data to the speaker for playback, etc.). The operating parameters of the sensors and other devices in the slave earphone processed by the first processor in the main earphone can be transmitted from the first transmission module to the second transmission module, and then transmitted by the second transmission module to the aforementioned sensors and other devices through the third data interface, thereby enabling the first processor to set and adjust the operating parameters of the sensors and other devices in the slave earphone. Since the first processor performs service processing in both the main and slave earphones, the aforementioned service control data generally does not need to be transmitted to the slave earphone.

[0158] It should be noted that the above Figure 4 , Figure 9 and Figure 11 The scenario shown can also be extended to the scenario described above where the headphones do not include a second processor; please refer to the above for details. Figure 12 The corresponding description in [the document] will not be repeated here.
