As shown in Figure 1(a), the present application discloses a wireless audio/video device 100. FIG. 1(a) uses a speaker as an example of the wireless audio/video device 100 for illustration, but the present application is not limited thereto. The wireless audio/video device 100 may include but is not limited to speakers, wireless earphones, various devices (such as smart TVs, smart glasses, displays) carrying speakers or video playback components (such as display components), and the like. The wireless audio/video device 100 supports a WiFi-based wireless multimedia transmission protocol and is configured to communicate with a smart device 200 that supports the WiFi-based wireless multimedia transmission protocol. Although a mobile phone is used as an example of the smart device 200 in FIG. 1(a) , the smart device 200 is not limited thereto and may include but is not limited to personal PCs, mobile phones, portable audio players, portable game consoles, tablets, and smart wearable devices. (such as smart watches, etc.).

In some embodiments, the WiFi-based wireless multimedia transmission protocol may include any one of the DLNA protocol, the AirPlay protocol, the Miracast protocol, and improved versions of protocols based thereon. The AirPlay protocol was developed by Apple. It can wirelessly transmit pictures, audio, and videos on iOS devices such as iPhone, iPad, and iPod touch to audio/video playback devices that support the AirPlay protocol through WiFi. DLNA was first proposed by Sony, Intel, Microsoft, etc., and its full name is DIGITAL LIVING NETWORK ALLIANCE. It aims to solve the interconnection and interoperability of various electronic devices (such as but not limited to the above-mentioned wireless audio/video device 100 and smart device 200), so that such as photos, Video and music content can be shared among the above devices. The Miracast protocol was developed by the Wi-Fi Alliance in 2012 and is a wireless display protocol based on Wi-Fi direct. Electronic devices that support this protocol can share video images wirelessly. For example, mobile phones can use the Miracast protocol to wirelessly play videos or photos directly on TVs or other devices.

As shown in FIG. 1(a) , the wireless audio/video device 100 may include a first system-on-chip 101 configured to share audio/video content from the smart device 200 . Please note that in this article, various components, such as the processing unit 101a, memory 101b, WiFi communication module 101c, BLE communication module 101d, codec, etc., as shown in Figure 2, can be implemented through SOC (system on chip), such as Implemented as a first system-on-chip 101. For example, various RISC (reduced instruction set computer) processor IPs purchased from ARM, etc. can be used as SOC processing The unit 101a (and the communication module, etc.) is used to perform corresponding functions, so that it can be implemented as an embedded system. Specifically, there are many modules (IP) available on the market, such as but not limited to memory, various communication modules (such as WiFi communication module 101c, BLE communication module 101d, etc.), codecs, caches, etc. Devices and so on. In some embodiments, chip manufacturers can also develop customized versions of these modules based on off-the-shelf IP. In addition, other components such as the antenna, sensor component 101e, speaker 101f, microphone 101g, etc. can be externally connected to the IP. Users can implement various communication modules, codecs, etc. by building ASICs (Application Specific Integrated Circuits) based on purchased IP or self-developed modules to reduce power consumption and costs. For example, users can also use FPGA (Field Programmable Gate Array) to implement various communication modules, codecs, etc., which can be used to verify the stability of the hardware design. For various communication modules, codecs, etc., buffers can usually be equipped to temporarily store the data generated during processing.

Combining FIG. 1(a) and FIG. 2, the first system-on-chip 101 may take the following steps to perform wireless communication.

After the smart device 200 is connected to the router 300, the first system-on-chip 101 may receive configuration information of the router 300 from the smart device 200 (step 201). Among them, the router 300 is needed to establish a wireless local area network on which the WiFi-based wireless multimedia transmission protocol relies. For example, the configuration information of the router 300 may include the network name and password of the router 300 . In some embodiments, the configuration information of the router 300 may include the Service Set Identifier (SSID for short), the Basic Service Set Identifier (BSSID for short), the media access control (BSSID) of the wireless router 300 that needs to be connected. Media Access Control (MAC) address, key and other information. The smart device 200 capable of connecting to the router 300 knows the configuration information of the router 300, so that the configuration information can be sent to the first system-on-chip 101. This process is also called a network distribution process.

In step 202, the first system-on-chip 101 may be connected to the router 300 based on the configuration information of the router 300, and according to the WiFi-based wireless multimedia transmission protocol, receive data from the smart device 200 or Audio/video data from a cloud server (not shown). The router 300 works wirelessly and serves as an information exchange hub in a wireless local area network. Generally speaking, the networking role defined by the WiFi-based protocol is called an access point (AP). Usually the router 300 is integrated with a WiFi access point and is used as a WiFi access point. When the user moves freely and the wireless audio/video device 100 he carries moves with him, if the router 300 is available (or the connection status is good), try to connect to the router 300 to exchange the shared information from the smart device via the router 300. 200 or cloud server audio/video data, so that the available router 300 can be fully utilized to share audio/video data stably and conveniently with low power consumption.

In step 203, the first system-on-chip 101 can determine the availability of the router 300. When detecting that the router 300 becomes unavailable, open a local soft connection created according to the configuration information of the router 300. The entry point 102 directly receives audio/video data from the smart device 200 via the enabled soft access point 102 according to the WiFi-based wireless multimedia transmission protocol. Specifically, the first system-on-chip 101 can determine the availability of the router 300 by determining whether it can continue to connect to the router 300 , and can also learn the connection status between the smart device 200 and the router 300 by communicating with the smart device 200 . As shown in FIG. 1(b) , if the wireless audio/video device 100 cannot be connected to the router 300 normally, or it is learned that the smart device 200 cannot be connected to the router 300 normally, it is determined that the router 300 is unavailable. The so-called local soft access point 102 means that the WiFi access point is implemented in software and integrated on the wireless audio/video device 100, that is, the wireless audio/video device 100 is configured through software so that it can be used as a WiFi access point. Access Point. In this way, the first system-on-chip 101 can dynamically monitor the availability of the router 300 and rely on the wireless audio/video device 100 itself (without relying on other relay components) to connect to the smart device 200 when the router 300 becomes unavailable. Moreover, since the enabled soft access point 102 is created based on the configuration information of the router 300, the smart device 200 can automatically connect to the soft access point without performing a complex network configuration process on the wireless audio/video device 100. 102, continue to share and transmit audio/video data stably and conveniently, allowing users to maintain a good audio-visual experience throughout the entire process of free movement.

Please note that steps 201-203 are not necessarily executed in the order and number of times shown in Figure 2, but can be executed alternately. The execution order of steps 201-202 and step 203 can also be exchanged without affecting the logic of each other. Specifically, after step 203, if the detection router 300 becomes available, that is, the first system-on-chip 101 can connect to the router 300 based on the current configuration information, the soft access point 102 will no longer be turned on, and the software will be restored as required. The WiFi-based wireless multimedia transmission protocol receives audio/video data from the smart device 200 or the cloud server via the router 300, thereby saving the power consumption of the wireless audio/video device 100 until the router 300 becomes unavailable again. That is, the wireless audio/video device 100 consumes its own energy and computing resources to turn on the soft access point 102 only when the router 300 cannot perform its duties as a WiFi access point. In some embodiments, the soft access point 102 includes a WiFi hotspot, has the same configuration information as the router 300, and can not only be used to connect the smart device 200 to obtain audio/video data, but also can be used to obtain audio/video data when needed. Instead of the router 300, it is used to establish a wireless local area network on which the WiFi-based wireless multimedia transmission protocol relies.

In Figure 1 (a) and Figure 1 (b), the smart device 200 connected to the router 300 is the smart device 200 connected to the soft access point 102, which is only an example. In some embodiments, the smart device 200 connected to the router 300 may be different from the smart device 200 connected to the soft access point 102 . That is to say, after the wireless audio/video device 100 such as earphones (speakers) completes the network distribution process (that is, it can be connected to the router 300), different mobile phones can be connected to them (earphones, speakers). This also applies to soft access point 102. For example, two mobile phones A and B can cooperate in this way. Mobile phone A assists the earphones (or speakers) in configuring the network, and then mobile phone B pushes music to the earphones (or speakers) through the enabled soft access point 102.

It is shown in FIG. 1(a) and FIG. 1(b) that a wireless audio/video device 100 such as a headset (speaker box) is successfully configured with a single router 300, which is only as an example. In fact, the wireless audio/video device 100 such as a headset (speaker) may have successfully configured with multiple routers 300 and save configuration information of the multiple routers 300 . The first system-on-chip 101 can select one from multiple configuration information to create the soft access point 102 according to the operating instructions from the mobile phone.

In some embodiments, the local soft access point 102 may be created in advance according to the configuration information of the router 300 before being turned on. For example, before it is detected that the router 300 becomes unavailable, the soft access point 102 can be pre-created and kept in a closed state until it is detected that the router 300 becomes unavailable and then enabled. In some embodiments, when it is detected that the router 300 becomes unavailable, the local soft access point 102 can be created and turned on according to the configuration information of the router 300 .

In step 201, the first system-on-chip 101 has obtained the configuration information of the router 300, which can be stored in, for example, the memory 101b (as shown in Figure 3). When the soft access point 102 is to be created, the stored configuration information of the router 300 may be called and the soft access point 102 may be created accordingly. That is to say, monitoring the available status (such as connection status) of the router 300 and creating and/or starting the soft access point 102 accordingly can be automatically implemented without manual intervention by the user, and there is no need to manually complete the pairing of the wireless audio/video device 100 During the network configuration process of the soft access point 102, there is no need to manually set the relevant configuration information of the soft access point 102 by the smart device 200, thereby further improving the user's experience of using the wireless audio/video device 100. In some embodiments, a user's manual input option may also be provided, allowing the user to manually input configuration information, so that the first system-on-chip 101 creates the soft access point 102 based on the manually input configuration information.

FIG. 4 shows a schematic diagram of a first example of a wireless communication process between a speaker (an example of a wireless audio/video device) and a mobile phone (an example of a smart device) according to an embodiment of the present application. As shown in Figure 4, the wireless communication mode of the speaker dynamically switches between mode one and mode two. In step 401, the mobile phone is connected to the router, which is used to establish a wireless LAN on which the Airplay protocol relies. In step 402, the mobile phone sends the configuration information of the router to the speaker through the WAC protocol defined by Apple or a custom method, which is also called the network configuration process of the mobile phone to the speaker. In step 403, the speaker connects to the router using the configuration information received in step 402. The configuration information usually includes the network name and password of the router. After connecting to the router, the speaker and the mobile phone establish a connection according to the Airplay protocol (referred to as "establishing Airplay connection" in this article) (step 404). In step 405, the mobile phone pushes the music data to the speaker for playback through the Airplay connection.

When the speaker is in an environment without a router, the speaker switches the wireless communication mode to mode two (step 406). At this time, the speaker can no longer try to connect to the router, but first uses the configuration information of the router obtained from the mobile phone distribution network to create and open a soft access point (SoftAP) with the same configuration. The number of WiFi hotspots created can be one or more (step 407). Next, the mobile phone connects to the soft access point created by the speaker (step 408). Since the mobile phone has already been connected to the router with the same configuration in step 401, it can automatically connect to the soft access point (WiFi hotspot) created by the speaker without the user having to manually enter network configuration information. Based on the enabled soft access point instead of the router, the speaker and the mobile phone establish a new Airplay connection according to the Airplay protocol (step 409). In step 410, the mobile phone pushes music to the speaker for playback through the newly established Airplay connection.

In some embodiments, the wireless audio/video device 100 may include at least one or a combination of audio devices, video devices, and smart devices with audio and/or video functionality that work together. The specific combination method may depend on the user's application scenario. For example, the wireless audio/video device 100 includes a combination of earphones and a display screen (when watching a movie), or may include a combination of earphones and smart glasses (when playing games). wait.

In some embodiments, the wireless audio/video device 100 may include groups of wireless audio devices that work together, with each group of wireless audio devices including a first wireless audio device and a second wireless audio device. For example, the set of wireless audio devices may include earphones having a first earphone and a second earphone, or a speaker assembly having a plurality of speakers corresponding to respective channels. The following description takes a wireless audio device - a wireless pair of earphones including a first earphone and a second earphone - as an example. Specifically, the first earphone is used as an example of the "first wireless audio device" and the second earphone is used as the "second wireless audio device". audio device” For example, the first system-on-chip included in the first earphone and the second system-on-chip included in the second earphone are uniformly represented by reference numeral 101 without distinction.

However, it should be noted that the following embodiments can also be flexibly applied to other wireless audio devices (such as wireless speakers), wireless video devices, or smart devices with audio and/or video functions, which will not be described again here.

In some embodiments, at least one wireless audio device, such as the first earphone 100 and/or the second earphone 100 , is configured to store configuration information received from the router of the smart device 200 . Wherein, the first headset 100 includes a first system-on-chip 101, and the first system-on-chip 101 is further configured to: when it is determined that the router becomes unavailable, turn on the router according to the configuration information of the router. The local first soft access point 102 directly receives the audio data from the smart device 200 via the enabled first soft access point 102 according to the DLNA protocol; and forwards the received audio data to the second headset. 100. As shown in Figure 5, the wireless connection 1 for transmitting audio data from the smart device 200 to the first soft access point 102 of the first earphone adopts the WiFi communication mode, and the first system-on-chip 101 forwards the audio data to the second The wireless connection 2 of the earphone 100 (actually the second system-on-chip 101 on the second earphone 100) can adopt different communication modes, such as Bluetooth communication mode (including but not limited to BLE mode, conventional Bluetooth communication mode, improved Bluetooth Communication mode, LE Audio communication mode, etc.), NFC communication mode, etc. By adopting a communication mode different from the WiFi communication mode between the first earphone 100 and the second earphone 100 , especially a communication mode that does not rely on wireless LAN, the first soft access point is only turned on at the first system-on-chip 101 102 can be applied to the current conventional DLNA protocol restrictions on access points. Specifically, the current conventional DLNA protocol usually adopts a 1-to-1 inherent configuration and only supports the first soft access point 102 to transmit the received audio data to the first headset 100 itself, for example, to store it in the memory of the first headset 100 itself. , using the Bluetooth communication module, NFC communication module, etc. usually provided on the first earphone 100, the audio data can be forwarded to the second earphone 100, which is also usually equipped with a Bluetooth communication module, etc. In this way, you can minimize the number of hotspots that are turned on. After all, hotspots bring the risk of privacy exposure. On the other hand, it can also reduce power consumption. Currently, many smart devices on the market, such as mobile phones, pads, etc., only support the conventional DLNA protocol, that is, smart devices can only send audio data to a wireless audio device through the DLNA protocol. Therefore, it is of great practical significance for multiple wireless audio devices (such as two headphones) to obtain audio data from smart devices that support the conventional DLNA protocol through the above method.

In some embodiments, the DLNA protocol can also be customized. As shown in FIG. 6 , the customized DLNA protocol allows the router or the first soft access point 102 of the first headset 100 that supports it to act as a repeater. Forward the received audio data to several wireless audio devices, including but not limited to One earphone 100 itself and a second earphone 100 . The first earphone 100 supports the customized DLNA protocol and is configured to communicate with the smart device 200 supporting the customized DLNA protocol. That is to say, through the customized DLNA protocol, the wireless connection 1 between the smart device 200 and the first earphone 100 is used to transmit audio data, and the wireless connection 1 between the first earphone 100 and the second earphone 100 is used to transmit audio data. The WiFi communication mode can be adopted, thereby significantly improving the relay utility of opening the first soft access point 102 without opening other WiFi hotspots. It is also applicable to wireless audio devices that only set up a single WiFi communication.

In some embodiments, when the smart device 200 only supports the conventional DLNA protocol, there is no need to use other communication protocols or communication methods to implement audio transmission between multiple wireless audio devices, or the DLNA protocol is used to implement multiple wireless audio devices. Audio transmission between audio devices. In addition to turning on the first soft access point 102 at the first earphone 100, an additional second soft access point 102 is also turned on at the second earphone 100 to realize the connection between the smart device 200 and the first earphone 100 and the second earphone. Sharing of audio data between 100's. Specifically, as shown in FIG. 7 , the first earphone 100 supports the DLNA protocol and is configured to communicate in WiFi communication mode via the first wireless connection 1 with the smart device 200 that supports the conventional DLNA protocol. The second headset 100 includes a second system-on-chip 101, and the second system-on-chip 101 is configured to: when the first headset 100 wants to forward audio data received from the smart device 200, create and open a local the second soft access point 102; directly receiving the audio data from the first earphone 100 via the turned-on second soft access point 102 according to the DLNA protocol. The first system-on-chip 101 is further configured to: create a new DLNA connection 1a; and forward the audio data to the second headset 100 via the first soft access point 102 through the new DLNA connection 1a. In some embodiments, the second soft access point 102 can also be turned on at the first earphone 100 to enable the first earphone 100 to transmit audio data to the second earphone 100 through a DLNA connection. In this embodiment, the first soft access point 102 and the second soft access point 102 can implement their functions at the same soft access point.

The following uses pairs of earphones as an example to give a detailed explanation of the use of AirPlay protocol.

At least one of the first earphone 100 and the second earphone 100 is configured to store the received configuration information of the router. Wherein, the first headset 100 includes a first system-on-chip 101, and the first system-on-chip 101 is configured to: when it is determined that the router becomes unavailable, enable local operation according to the configuration information of the router. The first soft access point 102 of the smart device directly receives the audio data from the smart device through the enabled first soft access point 102 according to the AirPlay protocol and sends it to the second wireless device via the first soft access point 102. audio devices. Unlike regular DLNA protocols, AirPlay is not limited to a one-to-one fixed configuration, but can relay audio data to multiple receivers For example, the first earphone 100 and the second earphone 100, or even other speakers, smart glasses, etc., thereby making the shared communication process more convenient.

Regarding the creation of the first soft access point 102, the first system-on-chip 101 may be further configured to: when it is determined that the router becomes unavailable, create the first soft access point 102 and turn it on. Alternatively, the first system-on-chip 101 page may be further configured to pre-create the local device after obtaining the configuration information of the router and before determining that the router becomes unavailable (that is, while the router is still available). The first soft access point 102 is just not turned on until the router is unavailable and then turned on. In this way, when the user is listening to music, for example, when the user moves outdoors and cannot connect to the previous router, it takes less time to activate the first soft access point 102 and the response is faster, so that the user does not feel the interruption of the router. Turn on to improve the smooth experience of music listening.

Returning to Figure 3, the first system-on-chip 101 typically includes a BLE communication module 101d. Smart devices usually also contain BLE communication modules. In some embodiments, the BLE communication module 101d can be utilized to maintain continuous and almost real-time monitoring of information about audio transmissions from smart devices with lower power consumption. Specifically, the first system-on-chip 101 may be configured to continuously communicate with the smart device via the BLE communication mode to learn whether the smart device indicates each wireless audio device (such as but not limited to the first earphone 100 and the second earphone). 100) To receive and/or play audio data; upon learning that the smart device instructs each wireless audio device to receive and/or play audio data and the router becomes unavailable, turn on the locally created first soft access point 102. Specifically, a smart device such as a mobile phone sends an instruction to receive and/or play audio data when the user opens the audio playback software or when the user clicks on the music file. When the smart device wants to transmit audio data and the router becomes unavailable, turning on the first soft access point 102 can reduce the power consumption of the wireless audio device when it is in standby or when it does not need to receive audio data. The privacy risk of WiFi hotspot being turned on for a long time can be sensitive to the fact that audio data needs to be played but the router becomes unused or becomes unavailable due to the distance, so as to achieve smooth transmission of audio data. On the contrary, in the case where the smart device does not instruct each wireless audio device (such as the first earphone 100) to receive and/or play audio data, the first earphone 100 continues to communicate with the smart device via the BLE communication mode, and the first earphone 100 continues to communicate with the smart device via the BLE communication mode. A soft access point 102 shuts down. For example, the smart device may stop playing audio data after a period of time. Then the first earphone 100, especially the first system-on-chip 101, can be converted to a state in which the BLE communication module 101d keeps working and the first soft access point 102 is turned off, so that it can Lower power consumption maintains continuous and near real-time monitoring of information about audio transmissions from smart devices while reducing wireless audio The power consumption of the device when it is in standby or when it does not need to receive audio data reduces the privacy risk of WiFi hotspots being turned on for a long time.

In some embodiments, regarding the determination of whether the router becomes unavailable, one or a combination of the connection status of the smart device and the router and the connection status of the first earphone 100 where the first system-on-chip 101 is located and the router can be considered. made. For example, the first system-on-chip 101 may be further configured to: via continuous communication with the smart device in the BLE communication mode, to learn whether the smart device cannot connect to the router, and if so, determine whether the smart device is unable to connect to the router. The router becomes unavailable. For another example, the first system-on-chip 101 may be further configured to determine whether the router cannot be connected, and if so, determine that the router has become unavailable. Specifically, it can be determined within a predetermined time period, such as several seconds, tens of seconds, etc., whether the connection continues to be unavailable. If so, it is determined that the router has become unavailable.

The router can be restored to a normal working state, similar to the above monitoring of the unavailable state of the router. The return to the normal state can also be detected by the first headset 100 itself, or the smart device can be informed in real time from the smart device via BLE communication. Check out the router and return to normal state. Specifically, the first system-on-chip 101 may be configured to continuously communicate with the smart device via the BLE communication mode to learn whether the smart device indicates each wireless audio device (such as but not limited to the first earphone 100 or the second earphone). 100) To receive and/or play audio data and whether the smart device is connected to the router; upon learning that the smart device instructs each wireless audio device to receive and/or play audio data and is connected to the router, according to the DLNA protocol or Airplay A protocol receives audio data from the smart device via the router. That is to say, once the router returns to normal working status and the smart device does have audio data to be pushed to the wireless audio device for playback, it will resume relaying audio data via the router according to the DLNA protocol or Airplay protocol, thereby reducing the number of wireless audio devices. power consumption, and disable soft access points that do not need to be enabled.

Information about whether the smart device instructs each wireless audio device (such as but not limited to the first earphone 100 or the second earphone 100) to receive and/or play audio data can be obtained from the smart device or through the current status of the wireless audio device. status to infer.

Take wireless in-ear headphones as an example for explanation. The first system-on-chip 101 of the first earphone 100 may be configured to: determine whether it is taken out from the charging box or whether it is in the ear, and if so, and the router becomes unavailable, open the locally created earphone. First soft access point 102. This setting cleverly takes into account the use of wireless in-ear headphones. When people want to use wireless headphones to play audio data, they usually take the headphones out of the charging box (or keep them outside the charging box without charging), or The person wears the headphones in their ears. When the first earphone 100 is taken out of the charging box or placed in the ear, it usually means that it may be used to play audio data. When the first earphone 100 is in the charging box or not worn in the ear, it means that it is not used to play audio data. The first soft access point 102 at the first earphone 100 can be turned off, thereby reducing the risk of not playing audio data. Power consumption and privacy exposure risks when using data.

In some embodiments, the first system-on-chip 101 can learn whether the first earphone 100 is in the charging box by performing wired (whether the contacts are in contact) or wireless communication (such as but not limited to BLE communication) with the charging box, and also Whether the first earphone 100 is in the charging box can be known through the sensor component 101e (see FIG. 3), such as but not limited to an optical sensor. Typically when inside the charging case, the optical sensor will detect a significant decrease in the energy of the incident light.

In some embodiments, the first system-on-chip 101 may perform in-ear detection through a sensor component 101e (see FIG. 3), such as but not limited to a capacitive sensor, an optical sensor, etc. Once the first earphone 100 is inserted into the ear, the detected light or capacitance will change significantly.
