Description

Technical Field

[0001] The present disclosure relates to the field of wireless communications, and more specifically, to a speaker assembly, a wireless audio playback system, and a communication method. Background Art

[0002] DLNA was first proposed by Sony, Intel, Microsoft, etc. The full name is DIGITAL LIVING NETWORKALLIANCE, which aims to solve the interconnection of wireless and wired networks including personal PCs, consumer electronics, and mobile devices. For example, computers and other electronic products, such as mobile phones and tablets, can be interconnected through wireless or wired networks to share photos, videos, and music among the above devices. Smart terminal devices such as mobile phones, tablets, and PCs can play music by passing music files to DLNA-supported speakers through DLNA technology, but most music player software can only support connecting to one DLNA speaker device and cannot meet the playback needs of multi-channel stereo speakers. Summary of the invention

[0003] The present disclosure is proposed to solve the above technical problems in the prior art. The present disclosure aims to provide a speaker assembly, a wireless audio playback system and a communication method, which can realize audio playback of multi-channel stereo speakers without changing the original DLNA protocol of the smart device playing audio and only connect to one speaker device supporting the DLNA protocol, while improving the efficiency of audio data sharing.

[0004] According to a first scheme of the present disclosure, a speaker assembly is provided, which includes at least two speakers, wherein one of the speakers serves as a first speaker, the first speaker is configured to establish a first DLNA connection with a smart device, receive a first control instruction from the smart device based on the first DLNA connection and execute an instruction of the first control instruction, and the first speaker establishes a respective second DLNA connection with at least one second speaker other than the first speaker, sends a second control instruction to each second speaker based on the respective second DLNA connection, and the second speaker is configured to receive the second control instruction based on the respective second DLNA connection and execute an instruction of the second control instruction.

[0005] According to a second scheme of the present disclosure, a wireless audio playback system is provided, including the speaker assembly according to the various embodiments of the present disclosure, or the speaker assembly according to the various embodiments of the present disclosure and a smart device.

[0006] According to a third scheme of the present disclosure, a communication method between a smart device and a speaker assembly is provided, wherein the speaker assembly includes at least two speakers, and the communication method includes the smart device selecting one of the speakers as the first speaker, the first speaker establishing a first DLNA connection with the smart device, receiving a first control instruction from the smart device based on the first DLNA connection and executing an instruction of the first control instruction, and the first speaker establishing a respective second DLNA connection with at least one second speaker other than the first speaker, sending the second control instruction to the respective second speakers based on the respective second DLNA connections, the respective second speakers receiving the second control instruction based on the respective second DLNA connections, and executing an instruction of the second control instruction based on the second control instruction.

[0007] Compared with the prior art, the embodiments of the present disclosure have the following beneficial effects:

[0008] The smart device only needs to use the existing DLNA protocol to identify a first speaker that supports the DLNA protocol and establish a first DLNA connection with the first speaker. The first speaker receives the first control instruction from the smart device based on the first DLNA connection and executes the instruction of the first control instruction. At the same time, the first speaker establishes a second DLNA connection with at least one second speaker other than the first speaker, sends a second control instruction to each second speaker based on the respective second DLNA connection, and each second speaker receives the second control instruction based on the respective second DLNA connection and executes the instruction of the second control instruction. The first speaker and the second speaker can thus achieve synchronous and coordinated multi-channel stereo audio playback. The existing smart device can only be connected to one first speaker, and cannot establish multiple DLNA connections with multiple second speakers, and cannot achieve multi-channel stereo playback. In the embodiments disclosed herein, the original DLNA protocol of the smart device does not need to be modified, and a first speaker can establish multiple DLNA connections with multiple second speakers. The first speaker only needs to inform the second speaker of the download address of the audio through the second control instruction, and the second speaker downloads the audio data according to the address by itself, without establishing an additional channel between the first speaker and the multiple second speakers to forward the audio data. Therefore, the efficiency of audio data sharing is greatly improved.

[0014] In order to enable those skilled in the art to better understand the technical solution of the present disclosure, the present disclosure is described in detail below in conjunction with the drawings and specific implementation methods. The embodiments of the present disclosure are further described in detail below in conjunction with the drawings and specific implementation methods, but are not intended to limit the present disclosure.

[0015] The words "first", "second" and similar words used in the present disclosure do not indicate any order, quantity or importance, but are only used to distinguish parts. The terms "first speaker" and "second speaker" used in the present disclosure are only used to distinguish. For example, in other embodiments, the "first speaker" may be the "second speaker" and the "second speaker" may be the "first speaker". Words such as "include" or "comprise" and similar words mean that the elements before the word include the elements listed after the word, and do not exclude the possibility of including other elements. "Up", "down", "left", "right" and the like are only used to indicate relative position relationships. When the absolute position of the described object changes, the relative position relationship may also change accordingly.

[0016] In the present disclosure, when a specific device is described as being located between a first component and a second component, there may or may not be an intermediary device between the specific device and the first device or the second device. When a specific device is described as being connected to other devices, the specific device may be directly connected to the other devices without an intermediary device, or may not be directly connected to the other devices but have an intermediary device. In the present disclosure, the arrows shown in the figures for each step are merely examples of the execution order, not limitations. The technical solution of the present disclosure is not limited to the execution order described in the embodiments. The various steps in the execution order may be combined, decomposed, or the order may be changed, as long as the logical relationship of the execution content is not affected.

[0017] All terms (including technical terms or scientific terms) used in the present disclosure have the same meanings as those understood by ordinary technicians in the field to which the present disclosure belongs, unless otherwise specifically defined. It should also be understood that terms defined in general dictionaries should be interpreted as having meanings consistent with their meanings in the context of the relevant technology, and should not be interpreted in an idealized or extremely formal sense, unless explicitly defined as such here. Techniques, methods and equipment known to ordinary technicians in the relevant field may not be discussed in detail, but where appropriate, the techniques, methods and equipment should be considered as part of the specification.

[0018] Figure 1 A schematic diagram showing the communication transmission between the speaker assembly and the smart device according to an embodiment of the present disclosure is shown. Figure 1 As shown, the speaker assembly includes at least two speakers, and the assembly of several speakers is set so that mobile users can obtain a good audio playback experience through the corresponding speakers at various locations. When each speaker is set to play audio data of different channels, the user can also enjoy a flexible and rich multi-channel audio playback experience. In some embodiments, one of the speakers can be used as the first speaker 101, and the first speaker 101 can be configured to establish a first DLNA connection with the smart device 102 based on the DLNA protocol, and receive a first control instruction from the smart device 102 based on the first DLNA connection and execute the instruction of the first control instruction. There are many ways to determine the first speaker 101. For example, when the DLNA protocol of the smart device 102 recognizes multiple speakers, the user can specify a speaker in the speaker assembly as the first speaker 101, or the smart device 102 randomly selects a speaker in the speaker assembly as the first speaker 101, etc., which are not listed here one by one.

[0019] The smart device 102 may be any portable smart terminal, including but not limited to a smart phone, a tablet computer, a laptop computer, a personal computer, a smart home, a wearable smart device, etc. For example, when the smart device 102 is a smart phone, the smart phone selects a speaker in the speaker assembly as the first speaker 101, and establishes a first DLNA connection with the first speaker 101. The smart phone sends a first control instruction to the first speaker 101 through the first DLNA connection, and the first control instruction may include the address of the audio data. After the first speaker 101 obtains the first control instruction through the first DLNA connection, it downloads the corresponding audio data based on the address of the audio data in the instruction.

[0020] Further, the first speaker 101 establishes respective second DLNA connections with at least one second speaker 103a, 103b, 103c, 103d and / or 103n other than the first speaker 101, and sends a second control instruction to each of the second speakers 103a, 103b, 103c, 103d and / or 103n based on the respective second DLNA connections. The first DLNA connection refers to a DLNA connection established between a smart device and a speaker. The second DLNA connection does not refer to a second DLNA connection, but refers to a DLNA connection established between one or more speakers and a speaker, so as to distinguish it from a DLNA connection established between a smart device and a speaker. For example, three speakers each establish three DLNA connections with a selected speaker (for example, as the first speaker 101), then these three DLNA connections are all referred to as second DLNA connections. If five speakers each establish five DLNA connections with a speaker, then these five DLNA connections are all referred to as second DLNA connections. The first DNLA connection and the second DLNA connection are used to distinguish different objects that are connected to each other. In addition, the second speaker does not refer to a certain speaker, but refers to a general term for one or more speakers that can establish one or more DLNA connections with a selected speaker (the first speaker 101 that establishes a first DLNA connection with the smart device 102). For example, there are five speakers in the speaker assembly, and one speaker is selected from the five speakers as the first speaker 101 to establish a first DLNA connection with the smart device 102. Then, among the remaining four speakers, if the remaining four speakers each establish their own second DLNA connection with the first speaker 101, then these four speakers are all called second speakers. Alternatively, if only three of the remaining four speakers establish their own second DLNA connection with the first speaker, then these three speakers are called second speakers.

[0021] like Figure 1As shown, in the case where the speaker assembly includes at least two speakers, in order to facilitate distinction, each speaker in the speaker assembly except the first speaker 101 is marked as 103a, 103b, 103c, 103d...103n. Since one speaker in the speaker assembly is selected as the first speaker 101, the remaining speakers in the speaker assembly can be used as the second speakers at the same time, or only some of the remaining speakers can be used as the second speakers. As an example, assuming that the speaker assembly includes four speakers, one of the speakers is selected as the first speaker 101, the first speaker 101 establishes a first DLNA connection with the smart device 102, and the first speaker 101 establishes respective second DLNA connections with the second speakers 103a and 103b (i.e., establishes two second DLNA connections), for example, the first speaker 101 and the second speaker 103a establish a second DLNA connection, and the first speaker 101 and the second speaker 103b establish another second DLNA connection. The first speaker 101 sends a second control instruction to the second speakers 103 a and 103 b based on their respective second DLNA connections. Figure 1 In the figure, the dotted line between the first speaker 101 and the second speaker 103c indicates that a second DLNA connection may be established between the first speaker 101 and the second speaker 103c. There is also a case where the second DLNA connection is not established. This is only an example and does not constitute a specific limitation on the protection scope.

[0022] Wherein, the second speakers 103a, 103b, 103c, 103d and / or 103n are configured to receive the second control instruction based on the respective second DLNA connections and execute the instructions of the second control instruction, and realize the communication between the first speaker 101 and each second speaker 103a, 103b, 103c, 103d and / or 103n through the respective second DLNA connections. For example, the second control instruction may include the download address of the audio to be played, and the second speakers 103a, 103b, 103c, 103d and / or 103n that establish their respective second DLNA connections with the first speaker 101 download the corresponding audio data after obtaining the second control instruction. The DLNA is the Digital Living Network Alliance, which aims to solve the interconnection and interoperability of wireless networks and wired networks including personal PCs, consumer electronics, and mobile devices. Specifically, Figure 1As a specific example, a mobile phone and a speaker assembly are used to form a local area network using a WIFI hotspot, wherein the specific form that does not rely on the WIFI hotspot can be an independent WIFI router or a WIFI hotspot integrated in the mobile phone. The first speaker 101 establishes a first DLNA connection with the mobile phone 102, wherein the mobile phone acts as DMC0 and the first speaker 101 acts as DMP0. At this time, the first speaker 101 acts as DMC1 and respectively establishes a second DLNA connection with the second speaker 103a (acting as DMP1) and the second speaker 103b (acting as DMP2).

[0023] The application software (such as a player) on the mobile phone sends a first control instruction to the first speaker 101 through the first DLNA connection. For example, the first control instruction controls the playback control functions of the first speaker 101 such as play, pause, volume adjustment, fast forward or fast rewind. At the same time, the first speaker 101 uses the respective second DLNA connections to send a second control instruction to the second speaker 103a and the second speaker 103b. The second control instruction can be the same control instruction as the first control instruction, or it can include other instructions. Each second speaker that establishes its own second DLNA connection with the first speaker 101 executes downloading audio data, playing, pausing, fast forwarding, or fast rewinding according to the instructions of the second control instruction. This embodiment solves the problem that most music player software can only support connecting to one DLNA speaker device, resulting in low data transmission efficiency and inability to balance the audio quality and synchronization of multiple speakers, and can meet the playback requirements of multi-channel stereo speakers.

[0024] In the above embodiment, the DMC is a digital media controller, which can be a smart terminal device with a basic operating interface. The DMP is a digital media player, which generally refers to the ability to find and play or output any media files provided by the DMS online. Some DMP devices include televisions, home theaters, printers, PDAs, multimedia phones, wireless screens, and some game console terminals. The full name of the DMS is digital media server, which provides the ability to acquire, record, store and serve as a source for media files. DMS, DMP, and DMC also include M-DMS, M-DMP, and M-DMC, namely mobile-DMS, mobile-DMP, and mobile-DMC, namely mobile DMS, mobile DMP, and mobile DMC.

[0025] In some embodiments, the first control instruction includes the address of the audio data and / or the playback control instruction of the audio data. For example, the user selects the audio data to be played by controlling the smart device 102, and sends the first control instruction to the first speaker 101, the first control instruction includes the address of the audio data to be played, and the first speaker 101 obtains the address and downloads the corresponding audio data. The first speaker 101 downloads the corresponding audio data based on the address of the audio data, which has a higher wireless transmission efficiency than using the smart device 102 to transmit the audio data to the first speaker 101. In addition, the first control instruction can also include the playback control instruction of the audio, for example, the smart device 102 informs the first speaker 101 to play the audio data. The playback control instruction includes the playback instruction of the audio data, the pause playback instruction, the volume adjustment instruction, the fast forward instruction or the fast rewind instruction, etc. The first speaker 101 performs the playback, pause, volume increase, volume decrease, fast forward or fast rewind of the audio data based on the first control instruction. The user can select or input the playback control instruction based on actual needs to meet the actual needs of the user.

[0026] DLNA is also used between the first speaker 101 and each second speaker 103a, 103b, 103c, 103d and / or 103n, so each second speaker 103a, 103b, 103c, 103d and / or 103n can also obtain audio data based on the address, avoiding the smart device 102 sending smart data to multiple speakers, or the audio data being transmitted again between multiple speakers. The shared audio data transmission efficiency is high, and the data delay is small, which is conducive to synchronous playback, etc.

[0027] In some embodiments, the second control instruction may include one or more of the address of the audio data, the channel configuration information of each second speaker, and the playback control instruction of the audio data. Through the respective second DLNA connections, the first speaker 101 sends the second control instruction to each second speaker to control each second speaker to obtain the audio data and play it. Among them, the second control instruction includes the address of the audio data, and the address of the audio data may be the same as or different from the address of the audio data contained in the first control instruction. Each second speaker, such as speakers 103a, 103b, 103c, 103d and / or 103n, plays together or in coordination with the first speaker 101 during the process of playing the audio data. The second control instruction may also include the channel configuration information of each second speaker. After each second speaker 103a, 103b, 103c, 103d and / or 103n obtains the channel configuration information, it plays the audio to be played respectively. In some embodiments, the audio data of each channel in the multi-channel audio data may be accompanied by a channel identifier, and the audio data of different channels may be stored at different addresses or at the same address, and each speaker downloads the audio data of the corresponding channel from different addresses, or downloads the audio data from the same address and selects to play based on the channel identifier. In some embodiments, the channel configuration information may also include personalized configuration of different audio data, for example, in the channel configuration information, it is specified that the first channel of the first song to be played is played by the first speaker 103a, and the second channel is played by the second speaker 103b, while the first channel of the second song to be played is played by the second speaker 103b, and the second channel is played by the first speaker 103a, and the like, so as to realize personalized playback of multi-channel stereo audio and flexible configuration of playback scenarios.

[0028] The channel configuration information may be set by the user, for example, the user sets the channel configuration information on the smart device 102 according to the quality or sound effect of the audio to be played. Alternatively, it is not necessary to include the channel configuration information in the second control instruction. In this case, each speaker in the speaker assembly may be pre-configured with its own channel identifier, so that each speaker can select the audio data of the corresponding channel according to the channel identifier for playback, thereby realizing multi-channel stereo playback of audio data. In some embodiments, for example, each speaker in the speaker assembly has been set at the factory or the user manually sets their own channel identifier after leaving the factory, such as the second speakers 103a and 103d are bass speakers for playing bass channel audio data, and the frequency band of the audio signal of the bass speakers is generally within 100Hz, 150Hz or 200Hz, while the second speakers 103b and 103c are used to play audio data outside the bass channel, etc. In some other embodiments, the audio data playback control instructions may also include instructions for executing playback, pause, volume up, volume down, fast forward, fast rewind or other controls of the audio data, so as to achieve synchronous control of audio playback of multiple speakers, and personalized adjustment of parameters such as the volume of audio data of different channels, so as to better realize the synchronous playback of multi-channel stereo audio and the configuration of various scenarios. Various application methods are not listed one by one.

[0029] In some embodiments, when the first speaker 101 receives the address of the audio data from the smart device 102 based on the first DLNA connection, the first speaker 101 is further configured to obtain the audio data from the DMS end based on the received address of the audio data and play it. For example, the application software on the mobile phone controls the first speaker 101 to play the audio file specified by the user through the first DLNA connection, such as the mobile phone transmits the URL (network address) of the audio file to the first speaker 101 through the first DLNA connection, and the first speaker 101 obtains the address of the audio file and downloads the audio data from the cloud server through the local DMPO (i.e., the first speaker 101) for playback.

[0030] In some embodiments, when the second speakers receive the address of the audio data based on their respective second DLNA connections, each second speaker is further configured to obtain the audio data from the DMS end based on the received address of the audio data and play it. Specifically, the first speaker 101 uses its respective second DLNA connection to control each second speaker to obtain information such as the URL for downloading audio data through its respective second DLNA connection, thereby downloading the audio data for playback. For example, the first speaker 101 transmits the URL of the audio file to each second speaker 103a, 103b, 103c and / or 103n through its respective second DLNA connection, and each second speaker 103a, 103b, 103c and / or 103n downloads the audio data from the cloud server for playback according to the audio data address.

[0031] Further, when each second speaker receives the address of the audio data and the channel configuration information of each second speaker based on its own second DLNA connection, each second speaker is further configured to obtain the audio data from the DMS end based on the address of the received audio data, and play one or more channels in the audio data based on the channel configuration information. Each second speaker 103a, 103b, 103c and / or 103n obtains the channel configuration information, and decides to play one or more channels in the audio file according to the channel configuration information. Each second speaker plays the audio data played by each second speaker according to its own channel identifier and the channel configuration information. Therefore, according to the embodiments of the present disclosure, it is possible to implement the media data transmission function and the playback control function for the DLNA multi-channel stereo speakers without changing the existing player software of smart terminals such as mobile phones and tablet computers, and achieve a multi-channel stereo experience effect. In this embodiment, the DMS end may be a smart device 102. For example, the audio data to be played is stored in the smart device 102. The first speaker 101 and each second speaker 103a, 103b, 103c and / or 103n access and download the audio data on the smart device 102 through the audio data address.

[0032] In some embodiments, the first DLNA connection and the second DLNA connection are established based on a WIFI channel or a Bluetooth channel. For example, the smart device 102 senses a speaker in the speaker assembly as the first speaker 101 and establishes a first DLNA connection. The smart device 102 sends a first control instruction to the first speaker 101 through the first DLNA connection. The first speaker 101 obtains the address of the audio data to be played in the first control instruction. The first speaker 101 uses the WIFI channel or the Bluetooth channel to download the corresponding audio data from the cloud server and play it.

[0033] In some embodiments, the first speaker 101 is further configured to identify the channel configuration information based on the first control instruction from the smart device 102, or, after the first speaker 101 obtains the audio data, automatically analyze the audio data to obtain the corresponding channel configuration information. For example, the first control instruction may include the channel configuration information, and the first speaker 101 can automatically identify the channel configuration information based on the first control instruction and play the audio data according to the respective channels. Of course, after obtaining the audio data, the first speaker 101 automatically analyzes the audio data, obtains the channel configuration information corresponding to the audio data, and sends the channel configuration information to each second speaker through the respective second DLNA connection, such as the second speakers 103a, 103b, 103c and / or 103n.

[0034] In some embodiments, the first speaker 101 and the second speaker can switch with each other. For example, when the smart device 102 wants to play the first audio file, in the speaker assembly composed of multiple speakers, the smart device 102 does not need to perceive the existence of multiple speakers. As long as the existing DLNA protocol finds a speaker device, the speaker device can be selected as the first speaker 101, that is, DMP0, and a first DLNA connection is established with the first speaker 101. The selected first speaker 101 is used as DMC1 to establish respective second DLNA connections with other second speakers, wherein the second speakers can be 103a, 103b, 103c and / or 103n. After playing the first audio file, when continuing to play the second audio file, the smart device 102 can select the second speaker 103c as the first speaker and establish a first DLNA connection with it, and the first speaker selected when playing the first audio file may establish a second DLNA connection with the first speaker when playing the second audio file, or may be in a standby state. The smart device 102 may select which speaker in the speaker assembly to serve as the first speaker 101 randomly, or may be selected by the user, or may be matched based on the audio quality of the audio file to be played, or may be switched based on factors such as the physical location of each speaker and the quality of its connection with other speakers, etc., which are not listed here one by one.

[0035] According to the embodiment of the present invention, each speaker in the speaker assembly establishes a multi-box playback system only through DLNA connection. Each speaker only needs to establish a connection with the smart device 102 or the interactive information between different speakers through DLNA, and the delay in establishing the multi-box playback system is shortened. There is no need for the first speaker 101 to establish a DLNA connection with the smart device 102 first, and then establish other connections between the first speaker 101 and the other second speakers. The user also does not need to intervene or manually configure the establishment of the connection between the first speaker 101 and the second speaker, which simplifies the operation and provides greater convenience for the user.

[0036] Figure 2 A timing diagram showing a process flow for switching a second speaker with a first speaker according to an embodiment of the present disclosure.

[0037] In some embodiments, the second speaker to be switched with the first speaker 101 is further configured to establish a first DLNA connection with the smart device 102 within a predetermined time period before the switch, receive the first control instruction from the smart device 102, and temporarily store the first control instruction in a memory (not shown) for sending to other speakers as the first speaker after the switch. Figure 2 As shown, the second speaker (step 201) that is switched with the first speaker 101 establishes a first DLNA connection with the mobile phone within a predetermined time period (i.e., the period from t1 to t2), and the second speaker (step 201) that is switched with the first speaker 101 receives a first control instruction based on the first DLNA connection (step 202), and temporarily stores the acquired first control instruction in a memory. In some embodiments, the length of the predetermined time period (i.e., the period from t1 to t2) is long enough so that the second speaker that is about to be switched to the first speaker has enough time to receive information related to assuming the responsibility of the first speaker and performing related control operations. In step 203, that is, switching is performed within the period from t2 to t3, and the switched first speaker 101 (assuming the responsibility of 103c) sends a second control instruction to other speakers (step 204), and the second control instruction can be exactly the same as the first control instruction, or other control instructions can be added on the basis of the first control instruction. For example, the first control instruction only includes the address of the audio data to be played. However, the first speaker 101 can obtain the channel configuration information of the audio data by automatically analyzing the audio data. At this time, the first speaker 101 obtains the first control instruction from the memory and then adds the channel configuration information to form a second control instruction and sends it to each second speaker, such as the second speakers 103a, 103b and / or 103n.

[0038] In the embodiment according to the present disclosure, the first speaker 101 and each second speaker transmit control commands or control information through their respective second DLNAs, and each second speaker obtains audio data based on the download address rather than the forwarding of the first speaker 101, which can greatly improve the transmission efficiency of the audio data that needs to be shared, reduce the overall delay of the audio data reaching each speaker, and thus improve the playback effect of multi-channel stereo audio. In addition, the first speaker 101 does not need to establish an additional data channel to forward audio data, which can also reduce the burden of data processing and transmission of the first speaker 101, reduce power consumption, and also reduce the interference that may be caused by multi-channel data transmission of the speaker device.

[0039] According to an embodiment of the present disclosure, a wireless audio playback system is also provided, including the speaker assembly described in each embodiment of the present disclosure, or including the speaker assembly described in each embodiment of the present disclosure and a smart device (such as Figure 1 The wireless audio playback system according to the embodiment of the present disclosure solves the problem that the smart device (taking a mobile phone as an example) only supports establishing a DLNA connection with one speaker, resulting in that the audio file can only be played on one speaker, so that multi-channel stereo audio playback based on multiple speakers can be achieved without changing the original DLNA protocol of the smart device.

[0040] Figure 3 A flow chart of a communication method between a smart device and a speaker assembly according to an embodiment of the present disclosure is shown, wherein the speaker assembly includes at least two speakers. In step 301, the smart device selects one of the speakers as the first speaker. Each speaker in the speaker assembly can listen to the establishment of DLNA, and the smart device only needs to sense one speaker in the speaker assembly as the first speaker and establish a first DLNA connection, and it does not need to sense the existence of the remaining speakers. Of course, the smart device can also replace the first speaker based on the user's choice or according to the characteristics of the audio data played each time. For example, assuming that there are four speakers in the speaker assembly, respectively marked as 103a, 103b, 103c, and 103d, when playing the first audio file, the smart device selects 103d as the first speaker, and the first speaker establishes a respective second DLNA connection with the second speakers 103a, 103b or the second speakers 103a, 103b and 103c. When playing the second audio file, the smart device replaces the first speaker, selects 103c as the first speaker, and establishes a second DLNA connection with the second speaker 103a. The first speaker and the second speaker are interchangeable, and the first speaker can select all remaining speakers except the first speaker as second speakers to establish their own second DLNA connection, or select only some of the remaining speakers as second speakers to establish their own second DLNA connection.

[0041] In step 302, the first speaker establishes a first DLNA connection with the smart device, receives a first control instruction from the smart device based on the first DLNA connection and executes an instruction of the first control instruction, and the first speaker establishes a respective second DLNA connection with at least one second speaker other than the first speaker, and sends the second control instruction to each second speaker based on the respective second DLNA connection, thereby realizing media data transmission function and playback control function for the DLNA multi-channel stereo speakers without changing the existing smart device playback software, thereby improving the transmission efficiency of audio data and user experience.

[0042] In step 303, each of the second speakers receives the second control instruction based on the respective second DLNA connection, and executes the instruction of the second control instruction based on the second control instruction.

[0043] In some embodiments, the method further includes pre-setting which channel's audio signal each speaker is to play, and after acquiring the audio data, extracting and converting the audio signals of each channel from the audio data to achieve a multi-channel stereo playback effect.

[0044] In some embodiments, when the first speaker receives the address of the audio data from the smart device based on the first DLNA connection, the audio data is obtained from the DMS based on the obtained address of the audio data. Each of the second speakers receives the address of the audio data based on the respective second DLNA connection, obtains the audio data from the DMS based on the address of the audio data and plays it. Or, when each of the second speakers receives the address of the audio data and the channel configuration information of each of the second speakers based on the respective second DLNA connection, the second speaker obtains the audio data from the DMS based on the received address of the audio data, and plays one or more channels in the audio data based on the channel configuration information.

[0045] In some embodiments, the first speaker and the second speaker can switch with each other, and the second speaker that switches with the first speaker establishes a first DLNA connection with the smart device within a predetermined time period before the switching, receives a first control instruction from the smart device, and temporarily stores the first control instruction in a memory for sending to other speakers after the switching.
