[0024] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the specific technical solution of the present application will be further described in detail below in conjunction with the drawings in the embodiments of the present application. The following embodiments are used to illustrate the present application, but are not used to limit the scope of the present application.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein are only for the purpose of describing the embodiments of this application and are not intended to limit this application.

[0026] In the following description, reference is made to “some embodiments”, which describe a subset of all possible embodiments, but it will be understood that “some embodiments” may be the same subset or different subsets of all possible embodiments and may be combined with each other without conflict.

[0027] It should be pointed out that the terms "first\second\third" involved in the embodiments of the present application are used to distinguish similar or different objects, and do not represent a specific ordering of the objects. It can be understood that "first\second\third" can be interchanged in a specific order or sequence where permitted, so that the embodiments of the present application described here can be implemented in an order other than that illustrated or described here.

[0028] The present application provides a wireless audio system. Figure 1 Schematic diagram of the structure of the wireless audio system of the present application embodiment. Figure 1As shown, the wireless audio system 100 includes: an audio gateway 101, a first audio output device 102, a second audio output device 103 and an audio source 104; wherein the first audio output device 102 has no wireless communication link with the second audio output device 103; the audio gateway 101 establishes a first wireless link 105 with the audio source 104, and sends a connection parameter 106 of the first wireless link 105 to the first audio output device 102 and the second audio output device 103; the first audio output device 102 and the second audio output device 103 receive the connection parameter 106, and receive the audio information 107 sent by the audio source 104 according to the connection parameter 106.

[0029] In some embodiments, the audio gateway 101 broadcasts the connection parameters 106 , thereby sending the connection parameters 106 to the first audio output device 102 and the second audio output device 103 .

[0030] The first audio output device 102 and the second audio output device 103 can each configure their transceivers according to the connection parameters 106 to receive audio information 107 from the audio source 104, establish a one-way wireless communication path 108 from the audio source 104 to 102, and a one-way wireless communication path 109 from the audio source 104 to 103. The communication path 108 enables the first audio output device 102 to spy, listen, or otherwise capture the audio information 107 sent by the audio source 104 through the communication path 108. The same is true for the communication path 109, enabling the second audio output device 103 to spy, listen, or otherwise capture the audio information 107 sent by the audio source 104 through the communication path 109.

[0031] It should be noted that the first wireless link 105 can be a connection of various protocol types. For example, the first wireless link 105 is a Bluetooth connection link, a proprietary protocol connection link, a point-to-point connection link, or a WiFi connection link. The so-called proprietary protocol refers to any wireless protocol other than a standard wireless protocol.

[0032] The connection parameters 106 enable the first audio output device 102 and the second audio output device 103 to receive the audio information 107 sent by the audio source 104. Taking the Bluetooth connection link as an example, the connection parameters 106 include but are not limited to the Bluetooth device address of the audio source 104, the local clock of the audio source 104, the logical transmission address and clock offset of the audio gateway 101, and the encryption parameters of the first wireless link 105 (such as a link key).

[0033] The present application embodiment further provides a wireless audio system, Figure 2 Schematic diagram of the structure of the wireless audio system of the present application embodiment. Figure 2As shown, the wireless audio system 200 includes: an audio gateway 101, a first audio output device 102, a second audio output device 103 and an audio source 104; and the wireless audio system 200 and Figure 1 The wireless audio system 100 shown in the figure is similar, and the similarities are not repeated here. Wherein, the connection parameter 106 is the connection parameter 201; the audio gateway 101 sends the connection parameter 106 of the first wireless link 105 to the first audio output device 102 and the second audio output device 103, including:

[0034] The audio gateway 101 sends the connection parameter 201 to the first audio output device 102 through the second wireless link 202 with the first audio output device 102; and sends the connection parameter 201 to the second audio output device 103 through the third wireless link 203 with the second audio output device 103; the connection parameter 201 enables the first audio output device 102 to extract the first channel information (CH1) in the audio information 204 (i.e., an example of the audio information 107) sent by the audio source 104, and the connection parameter 201 enables the second audio output device 103 to extract the second channel information (CH2) in the audio information 204.

[0035] The first audio output device 102 and the second audio output device 103 receive the audio information 204 sent by the audio source 104 according to the connection parameter 201; and the first audio output device 102 extracts the first channel information (CH1) from the audio information 204 according to the connection parameter 201, and the second audio output device 103 extracts the second channel information (CH2) from the audio information 204 according to the connection parameter 201;

[0036] The audio gateway 101 determines, via the second wireless link 202 , whether the first audio output device 102 receives the audio information 204 ;

[0037] The audio gateway 101 determines whether the second audio output device 103 receives the audio information 204 through the third wireless link 203;

[0038] When the audio gateway 101 determines that the first audio output device 102 and the second audio output device 103 have received the audio information 204, the audio gateway 101 sends a third ACK information 205 to the audio source 104 through the first wireless link 105 in the next time slot of the current transmission time slot (recorded as time slot N+1, N is an arbitrary integer).

[0039] The audio source 104 receives the third ACK information 205 in the time slot N+1. At this point, a complete transceiver process is completed. The audio source 104 can send new audio information in the time slot N+2, or send new audio information in the idle time of the time slot N+1.

[0040] In some embodiments, the audio gateway 101 receives an indication corresponding to whether the first audio output device 102 has received the audio information 204 through the second wireless link 202 to determine whether the first audio output device 102 has received the audio information 204. For example, if the audio gateway 101 receives NACK information returned by the first audio output device 102, it is determined that the device 102 has not received the audio information 204. On the contrary, if the audio gateway 101 receives ACK information returned by the device 102, it is determined that the device 102 has received the audio information 204. For another example, if the audio gateway 101 does not receive ACK information returned by the first audio output device 102 within a predetermined time, it is determined that the device 102 has not received the audio information 204. On the contrary, if the audio gateway 101 receives ACK information returned by the device 102 within the predetermined time, it is determined that the device 102 has received the audio information 204.

[0041] In some embodiments, the audio gateway 101 receives an indication corresponding to whether the second audio output device 103 has received the audio information 204 through the third wireless link 203 to determine whether the second audio output device 103 has received the audio information 204. For example, if the audio gateway 101 receives NACK information returned by the second audio output device 103, it is determined that the device 103 has not received the audio information 204. On the contrary, if the audio gateway 101 receives ACK information returned by the device 103, it is determined that the device 103 has received the audio information 204. For another example, if the audio gateway 101 does not receive ACK information returned by the second audio output device 103 within a predetermined time, it is determined that the device 103 has not received the audio information 204. On the contrary, if the audio gateway 101 receives ACK information returned by the device 103 within the predetermined time, it is determined that the device 103 has received the audio information 204.

[0042] It should be noted that the second wireless link 202 can be a connection of various protocol types, for example, the second wireless link 202 is a Bluetooth connection link, a proprietary protocol connection link, a point-to-point connection link or a WiFi connection link.

[0043] Similarly, the third wireless link 203 may also be a connection of various protocol types. For example, the third wireless link 203 is a Bluetooth connection link, a proprietary protocol connection link, a point-to-point connection link, or a WiFi connection link. The so-called proprietary protocol refers to any wireless protocol other than a standard wireless protocol.

[0044] In some embodiments, the audio gateway 101 can automatically establish a connection with 102 and 103 according to the pre-saved connection information with 102 and 103 (e.g., Bluetooth pairing information) after 102 and 103 are powered on, that is, establish a second wireless link 202 with the first audio output device 102, and establish a third wireless link 203 with the second audio output device 103.

[0045] It can be understood that, since in the wireless audio system 200, the audio output devices 102 and 103 only establish one wireless link, their behaviors are consistent, and no distinction is made between a master device and a slave device. Thus, on the one hand, the power consumption of the two devices when working is lower; on the other hand, since the behaviors of the audio output devices 102 and 103 are completely consistent, when one audio output device stops working, the other audio output device can continue to work without any switching.

[0046] The present application embodiment further provides a wireless audio system, Figure 3 Schematic diagram of the structure of the wireless audio system of the present application embodiment. Figure 3 As shown, the wireless audio system 300 includes: an audio gateway 101, a first audio output device 102, a second audio output device 103 and an audio source 104; and the wireless audio system 300 and Figure 2 The wireless audio system 200 shown is similar, and the similarities are not repeated here. The difference is that when the audio gateway 101 determines that the first audio output device 102 and / or the second audio output device 103 have not received the audio information 204, it sends a NACK message 301 to the audio source 104 through the first wireless link 105 in the next time slot (i.e., time slot N+1) of the current transmission time slot.

[0047] The audio source 104 receives the NACK information 301 in the time slot N+1, and thus completes a complete transceiver process. The audio source 104 can resend the audio information 204 in the time slot N+2, or send new audio information in the idle time of the time slot N+1.

[0048] It should be noted that the audio gateway 101 described in the embodiment of the present application can be various electronic devices with wireless communication capabilities, for example, the audio gateway 101 is a charging box for audio output devices 102 and 103, a wearable device (such as a smart bracelet, a smart watch, or smart glasses, etc.), or another device of the same type that is not the same device as the audio source (such as another mobile phone), etc.

[0049] The audio source 104 may be any electronic device that has wireless communication capabilities and can transmit audio information, for example, the audio source 104 is any mobile phone, portable game console, portable media player (such as MP3 player, MP4 player, etc.), an audio / video (A / V) receiver as part of a home entertainment or home theater system, a tablet computer, a personal computer or a laptop computer, etc. For example, an A / V receiver may have wireless and wired speakers.

[0050] Audio output devices 102 and 103 can be wireless rear channel speakers or something similar. Audio output devices 102 and 103 are configured as any type of electroacoustic transducer for converting audio information into sound, such as home or professional speakers, headphones, earphones, or car headphones. The present application is not limited to any specific physical format or size of the audio source and audio output device configuration. The first audio output device 102 can be a left channel speaker, and the second audio output device 103 can be a right channel speaker, or vice versa. Any of the speakers can be configured as any stereo channel.

[0051] The present application embodiment further provides a wireless audio system, Figure 4 Schematic diagram of the structure of the wireless audio system of the present application embodiment. Figure 4 As shown, the wireless audio system 400 includes: an audio gateway 101, a first audio output device 102, a second audio output device 103 and an audio source 104; and the wireless audio system 400 and Figure 1 The wireless audio system 100 shown in FIG. 1 is similar in manner, and the similarities are not described again here. For the sake of simplicity, the connection parameter 201 is not shown in the figure, and can be referred to as Figure 3 .

[0052] When the first audio output device 102 receives the audio information 204 in the second predetermined part 401 of the current transmission time slot (recorded as time slot N), the first ACK information 402 corresponding to the audio information 204 is sent to the audio gateway 101 through the second wireless link 202 in the first predetermined part 403 of the current transmission time slot; wherein the first ACK information 402 indicates that the first audio output device 102 has received the audio information 204;

[0053] When the audio gateway 101 receives the first ACK information 402 corresponding to the audio information 204 in the first predetermined part 403 of the current transmission time slot through the second wireless link 202, it is determined that the first audio output device 102 has received the audio information 204; of course, if the audio gateway 101 does not receive the first ACK information 402 in the first predetermined part 403 through the second wireless link 202, it is determined that the first audio output device 102 has not received the audio information 204; for example, the audio gateway 101 receives the NACK information sent by the first audio output device 102 in the first predetermined part 403, then it is determined that the device 102 has not received the audio information 204; for another example, if the audio gateway 101 does not receive any information from the device 102 in the first predetermined part 403, then it is determined that the device 103 has not received the audio information 204.

[0054] Similarly, when the second audio output device 103 receives the audio information 204 in the second predetermined part 401 of the current transmission time slot (recorded as time slot N), the second ACK information 404 corresponding to the audio information 204 is sent to the audio gateway 101 through the third wireless link 203, in the third predetermined part 405 after the first predetermined part 403 of the current transmission time slot; wherein the second ACK information 404 indicates that the second audio output device 103 has received the audio information 204;

[0055] When the audio gateway 101 receives the second ACK information 404 corresponding to the audio information 204 in the third predetermined part 405 through the third wireless link 203, it is determined that the second audio output device 103 has received the audio information 204; of course, when the audio gateway 101 does not receive the second ACK information 404 corresponding to the audio information 204 in the third predetermined part 405 through the third wireless link 203, it is determined that the second audio output device 103 has not received the audio information 204; for example, the audio gateway 101 receives the NACK information sent by the second audio output device 103 in the third predetermined part 405, then it is determined that the device 103 has not received the audio information 204; for another example, the audio gateway 101 does not receive any information from the device 103 in the third predetermined part 405, then it is determined that the device 103 has not received the audio information 204. Among them, the timing relationship between the second predetermined part 401, the first predetermined part 403 and the third predetermined part 405 is as follows: Figure 5 shown.

[0056] When the audio gateway 101 receives the first ACK information 402 and the second ACK information 404, it sends the third ACK information 205 to the audio source 104 in the time slot N+1 through the first wireless link 105. The audio source 104 receives the third ACK information 205 in the time slot N+1, and thus completes a complete transceiver process. The audio source 104 can send new audio information in the time slot N+2, or send new audio information in the idle time of the time slot N+1.

[0057] Of course, if the audio gateway 101 does not receive the first ACK information 402 and / or the second ACK information 404, the NACK information 301 is sent to the audio source 104 through the first wireless link 105 in the next time slot of the current transmission time slot (that is, time slot N+1). The scene of sending the NACK information 301 is not shown in the figure. The audio source 104 receives the NACK information 301 in the time slot N+1 through the first wireless link 105. At this point, a complete transceiver process is completed. The audio source 104 can resend the audio information 204 in the time slot N+2, or send new audio information in the idle time of the time slot N+1.

[0058] In some embodiments, the audio source 104 may wirelessly transmit an audio stereo information stream in the form of one or more packets. Each packet incorporates stereo audio information in the form of compressed or uncompressed stereo samples. The stereo audio information includes stereo samples of first channel information and second channel information (such as left and right channels or the like).

[0059] Figure 5 501 to 509 are timing diagrams of nine different scenarios of the wireless audio system 400 between two consecutive time slots N and time slot N+1, as shown in FIG. Figure 5 As shown, wherein, scene 501, the scene 501 is that both audio output devices 102 and 103 can receive audio information sent by the audio source. In the scene 501, during slot N (i.e., the second predetermined part 401 of the current transmission slot), the audio source sends dual-channel stereo wireless audio information, at which time the audio gateway may not receive the audio information, and the audio output devices 102 and 103 receive the audio information by monitoring, and during the remaining idle time of slot N, during the first predetermined part 403 of the current transmission slot, the first audio output device sends the first ACK information to the audio gateway, and during the third predetermined part 405 of the current transmission slot, the second audio output device sends the second ACK information to the audio gateway, and when the audio gateway receives the ACK information sent by the audio output devices 102 and 103 during these two periods, during the next slot N+1, the audio gateway sends the third ACK information to the audio source, thus completing a complete transceiver process.

[0060] For abnormal scenarios, that is, scenarios 502 to 509; in scenario 502, both audio output devices 102 and 103 can receive audio information, and both send ACK information to the audio gateway after receiving the audio information, but the audio gateway only receives the second ACK information sent by the second audio output device. In this scenario, the audio gateway sends a NACK message to the audio source during the next time slot N+1.

[0061] Scenario 503 is that both audio output devices 102 and 103 can receive audio information, and after receiving the audio information, both send ACK information to the audio gateway, but the audio gateway only receives the ACK information sent by the first audio output device. In this scenario, the audio gateway sends a NACK message to the audio source during the next time slot N+1.

[0062] Scenario 504 is that both audio output devices 102 and 103 can receive audio information, and after receiving the audio information, both send ACK information to the audio gateway, but the audio gateway does not receive ACK information from any headset. In this scenario, the audio gateway sends NACK information to the audio source during the next time slot N+1.

[0063] Scenario 505 is that only the second audio output device receives the audio information. After receiving the audio information, the second audio output device sends a second ACK information to the audio gateway, and the audio gateway receives the second ACK information sent by the second audio output device. In this scenario, the audio gateway sends a NACK message to the audio source during the next time slot N+1.

[0064] Scenario 506 is that only the first audio output device receives the audio information, and the first audio output device sends a first ACK message to the audio gateway after receiving the audio information, and the audio gateway receives the first ACK message sent by the first audio output device. In this scenario, the audio gateway sends a NACK message to the audio source during the next time slot N+1.

[0065] Scenario 507 is that only the second audio output device receives the audio information. After receiving the audio information, the second audio output device sends a second ACK message to the audio gateway, but the audio gateway does not receive the second ACK message sent by the second audio output device. In this scenario, the audio gateway sends a NACK message to the audio source during the next time slot N+1.

[0066] Scenario 508 is that only the first audio output device receives the audio information, and the first audio output device sends the first ACK information to the audio gateway after receiving the audio information, but the audio gateway does not receive the first ACK information sent by the first audio output device. In this scenario, the audio gateway sends a NACK message to the audio source during the next time slot N+1.

[0067] Scenario 509 is an abnormal scenario in which both audio output devices do not receive the audio information sent by the audio source. If the audio gateway does not receive the ACK information returned by the two audio output devices during 510 and 511, the audio gateway sends a NACK message to the audio source during the next time slot N+1.

[0068] Abnormal scenarios are not listed here, and other abnormal scenarios can be permutations and combinations of the above abnormal scenarios. In short, the scenario where the audio gateway does not receive ACK information during at least one of the agreed 510 period and 511 period is an abnormal scenario. In this scenario, the audio gateway sends NACK information to the audio source during the next time slot N+1.

[0069] In some embodiments, after receiving the NACK information, the audio source may resend the audio information sent last time in the next time slot N+1 or the next time slot N+2 of the next time slot.

[0070] Related TWS technologies, such as Figure 6 As shown, two earphones are distinguished as a main earphone 61 and an auxiliary earphone 62, and simultaneously monitor the wireless audio information sent by the audio source 63. The main earphone 61 establishes a two-way auxiliary wireless link with the audio source 63 to receive and confirm the receipt of the audio information. The main earphone 61 and the auxiliary earphone 62 communicate with each other via the main wireless link. The audio source 63 transmits the audio information to the main earphone 61 via the auxiliary wireless link configured according to the standard wireless protocol. The main earphone 61 confirms the successful reception of the audio information via the auxiliary wireless link.

[0071] However, the main earphone 61 has to connect to two wireless links at the same time, acting as both a master and a slave, which consumes more power, resulting in a large difference in power consumption between the main earphone 61 and the slave earphone 62.

[0072] Moreover, before the main earphone 61 is inserted into the charging box, it is necessary to switch roles with the auxiliary earphone 62, which makes the design more complicated.

[0073] Based on this, an exemplary application of an embodiment of the present application in a practical application scenario will be described below.

[0074] In the embodiment of the present application, an audio gateway is introduced for the audio transmission mode of TWS earphones. It can be an earphone charging box or a wearable device (such as a smart watch or bracelet). The audio gateway can save the pairing information with the two earphones at the factory, such as Figure 7In the wireless audio system 700 shown, once the two headphones 701 and 702 are powered on, the audio gateway 101 automatically establishes a connection with the two headphones. The audio gateway 101 will establish a second wireless link 202 (the second wireless link) with the headphone 701, that is, the speaker 1 (LOUDSPEAKER1, an example of the first audio output device 102), and establish a third wireless link 203 (the third wireless link) with the headphone 702, that is, the speaker 2 (LOUDSPEAKER2, an example of the second audio output device 103). Once the audio gateway 101 establishes a connection with the two headphones, it also automatically establishes a connection with the audio source (audio source) 104 (such as a mobile phone), that is, the first wireless link 105 (the first wireless link). After the audio gateway 101 and the audio source 104 establish a connection, the audio gateway 101 passes the connection parameters with the wireless link 105 (the parameters include but are not limited to the Bluetooth device address (BD ADDR) of the audio source 104 and the local clock (CLKN) of the audio source 104, the logical transmission address (LT ADDR) and clock offset of the audio gateway 101, and the encryption parameters of the link between the audio gateway 101 and the audio source 104, such as the link key, etc.) to the earphone 701 and the earphone 702 through the wireless link 202 and the wireless link 203. Thereafter, when the audio source 104 sends a stereo audio data packet, the earphone 701 and the earphone 702 both receive the stereo audio data packet through wireless monitoring, and each plays the audio of one of the channels.

[0075] When the headset 701 receives the audio data packet, it sends an ACK packet to the audio gateway 101 at a fixed time in the remaining idle time of the current time slot. Similarly, when the headset 702 receives the audio data packet, it also sends an ACK packet to the audio gateway 101 at another fixed time in the remaining idle time of the current time slot. After the audio gateway 101 receives two ACK packets, it sends an ACK packet to the audio source 104 in the next time slot. A complete sending and receiving process is completed.

[0076] In the embodiment of the present application, the audio gateway is introduced. On the one hand, it can ensure that the left and right earphones only establish an asynchronous connectionless (ACL) link, and the behaviors are consistent, so theoretically the power consumption should be basically the same. Moreover, compared with the relevant wireless audio system, the wireless audio system provided in the embodiment of the present application does not distinguish between the primary and secondary earphones, so it is more power-saving.

[0077] On the other hand, the left earphone and the right earphone of the embodiment of the present application behave in exactly the same way. When one earphone is placed in the charging box, the other earphone can continue to work without any switching.

[0078] In the embodiment of the present application, an audio gateway is introduced, which communicates with the mobile phone as an intermediary to ensure that there is only one wireless link with the mobile phone, thereby ensuring that no compatibility changes are required on the mobile phone side, and the audio gateway is responsible for passing the relevant parameters connected to the mobile phone to the left and right earphones, allowing the left and right earphones to monitor the audio data, and then sending an ACK packet to the audio gateway, which returns the ACK packet to the mobile phone as an intermediary. The advantage of this method is that it unifies the implementation methods of the left and right earphones, reduces the power consumption of the left and right earphones, and entrusts the work of synchronizing with the mobile phone to the audio gateway device with higher power consumption.

[0079] The key point of the technical solution of this application is to introduce an audio gateway. Step A is to establish a wireless link between the audio gateway and the audio source. Step B is to establish a wireless link between the audio gateway and the left earphone and the right earphone respectively, so as to synchronize the wireless link parameters established with the audio source to the left earphone and the right earphone, so that the left and right earphones can monitor the audio data sent by the audio source.

[0080] In some embodiments, step B can be replaced by step B', where B' means that the audio gateway can also notify the left earphone and the right earphone of the wireless link parameters established by the audio gateway and the audio source by broadcasting without establishing a wireless link, so that the left earphone and the right earphone can monitor the audio data sent by the audio source.
