Some DMP devices include televisions, home theaters, printers, PDAs, multimedia handsets, wireless screens, and some game terminals. Wherein DMS, DMP and DMC also include M-DMS (mobile DMS), M-DMP (mobile DMP) and M-DMC (mobile DMC), respectively.

The expressions "first DLNA connection" and "second DLNA connection" herein are merely to distinguish DLNA connections for the purpose of expression and are not intended to limit the number, and "first DLNA connection" and "second DLNA connection" may also be based on the same DLNA protocol or different DLNA protocol connections. In each flow described herein, the order of steps shown in the drawings is merely an example, and related steps may be flexibly executed in a different order from that shown in the drawings without affecting the logical relationship of the respective steps.

Fig. 1 shows a schematic diagram of a wireless audio playback system according to an embodiment of the present disclosure. As shown in fig. 1, the wireless audio playback system 10 is composed of a headphone assembly 101 and a smart device 102. The headset assembly 101 includes a pair of

headphones

1011 and 1012, each of which supports DLNA protocol, wherein either one of the

headphones

1011 and 1012 can be used as a master headphone, and the other one can be used as a slave headphone, and the headphones 1011 shown in fig. 1 currently take on the function of the master headphone. The master earpiece 1011 is configured to establish a first DLNA connection with the smart device 102 based on a DLNA protocol, receive a first control command from the smart device 102 using the first DLNA connection, and execute the first control command. As shown in fig. 1, the master earphone 1011 may also establish a second DLNA connection with the slave earphone 1012 based on a DLNA protocol, and send a second control instruction to the slave earphone 1012 by using the second DLNA connection; the slave headset 1012 is configured to receive the second control instruction using the second DLNA connection and execute the second control instruction.

According to the embodiment of the present disclosure, the master earphone 1011 establishes a first DLNA connection with the intelligent device 102 based on a DLNA protocol, and the master earphone 1011 also establishes a second DLNA connection with the slave earphone 1012 based on the DLNA protocol, so that a true wireless earphone system is established between the two earphones and the intelligent device 102 only through the DLNA connection, and no other proprietary protocol is required, thereby reducing the overhead of each earphone. Because the intelligent device 102 establishes the first DLNA connection with the master earphone 1011 and simultaneously establishes the second DLNA connection between the master earphone 1011 and the slave earphone 1012, the time delay for establishing a binaural system is shortened, the master earphone 1011 does not need to establish the DLNA connection with the intelligent device 102 first and then transmit audio data between the master earphone and the slave earphone by using other private protocols, a large amount of protocol overhead and data transmission time are saved, the wireless transmission efficiency is improved, and the consumption of precious communication resources and power of the wireless earphone is reduced.

Specifically, the master earphone 1011 according to an embodiment of the present disclosure establishes a first DLNA connection (denoted as DLNA 0) with the smart device 102, wherein the smart device 102 is a digital media controller (denoted as DMC 0) and the master earphone 1011 acts as a digital media player (denoted as DMP 0). The master earphone 1011 establishes a second DLNA connection (denoted DLNA 1) with the slave earphone 1012, where the master earphone 1011 acts as a digital media controller (denoted DMC 1) and the slave earphone 1012 acts as a digital media player (denoted DMP 1). The intelligent device 102 only needs to establish DLNA connection with the master earphone 1011 according to the existing DLNA protocol, so that the presence of the slave earphone does not need to be sensed, that is, the intelligent device 102 does not need to modify the existing DLNA protocol; and the software and hardware of the smart device 102 that supports only one DLNA connection need not be upgraded.

In other embodiments, both of the two earphones of the earphone assembly 101 may monitor the DLNA establishment process, the smart device 102 may discover one or both earphones of the earphone assembly 101, and randomly or according to a certain rule (for example, strength of a connection signal, etc.) establish a DLNA connection with one of the earphones, the earphone that establishes the DLNA connection with the smart device 102 serves as a master earphone (1011), the other earphone serves as a slave earphone (1012), and a DLNA connection is also established between the master earphone 1011 and the slave earphone 1012, so that as long as both earphones support the DLNA protocol, the two earphones can indiscriminately assume the role of the master earphone, and thus the master earphone and the slave earphone can be switched with each other. Specifically, in the wireless audio playing system 10, the smart device 102 may select one earphone as the DMP0 and the main earphone 1011 to establish a DLNA connection with the earphone. In the process of establishing the first DLNA connection by the smart device 102 (as the DMC 0), when the smart device 102 finds two earphones, any one of the earphones is selected as the DMP0 and establishes the first DLNA connection with the earphone, the selected earphone is used as the master earphone 1011, and the selected earphone can also be used as the DMC1 to establish a DLNA connection with another earphone while serving as the DMP0, and the other earphone is the slave earphone 1012. Therefore, the earphone and the intelligent device are connected through the DLNA only to establish a true wireless earphone system. Because each earphone is connected through the DLNA to establish the binaural system, the connection is not required to be established through other private protocols and audio data is forwarded, so that the overhead of each earphone is greatly reduced, the time delay of establishing the binaural system and sharing the audio data is shortened, the establishing process of the connection between the master earphone and the slave earphone is not required to be interfered by a user or configured to operate, and the convenience of the user is greatly improved.

In the present disclosure, a mobile phone is taken as an example of the smart device, and other terminals such as ipad, computer, etc. may also be taken as examples, which are not specifically limited herein. An application program such as a music player may be installed in an intelligent device such as a mobile phone. The earphone assembly 101 is a true wireless stereo earphone, and on the basis of an original DLNA protocol, the mobile phone establishes a first DLNA connection with one DLNA device, i.e., the master earphone 1011, and the master earphone supports establishment of a plurality of (at least two) DLNA connections, so that it can establish a second DLNA connection with the slave earphone 1012 under the condition of establishing the first DLNA connection with the smart device 102 such as the mobile phone. The user can realize the playing of the audio data in the earphone component 101 by operating the mobile phone and the audio player in the mobile phone.

In some embodiments, the first control instruction may include an address of audio data and/or a play control instruction of the audio data, and the second control instruction includes an address of audio data and/or a play control instruction of audio data. When the master earphone 1011 receives the address of the audio data from the smart device 102 using the first DLNA connection, the master earphone 1011 is further configured to acquire the audio data from the DMS terminal 20 and play the audio data based on the address of the audio data. The master earpiece 1011 receives the address of the audio data from the smart device 102 using the first DLNA connection. In some embodiments, the audio file or the audio data may be stored in the smart device 102 such as a mobile phone, or may be stored in the cloud, so that the address of the audio data may be a URL (Uniform Resource Locator), and after receiving the URL of the audio file or the audio data, the main headset 1011 may directly download the audio data from the DMS terminal 20 according to the URL and play the audio data. In some embodiments, the DMS terminal 20 may be a cloud server as shown in fig. 1.

Likewise, when the slave headset 1012 receives the address of the audio data using the second DLNA connection, the slave headset 1012 is further configured to acquire the audio data from the DMS terminal 20 and play it based on the address of the audio data. The master earpiece 1011 receives the address of the audio data from the smart device 102 using the first DLNA connection. Meanwhile, the master earphone 1011 transmits the address of the audio data to the slave earphone 1012 using the second DLNA connection. The smart device 102 controls the master headset 1011 to play the audio file or audio data designated by the user through the first DLNA connection. Meanwhile, the main earphone 1011 uses the second DLNA connection control to obtain information such as a URL of the downloaded audio data from the earphone 1012, and the audio data is downloaded from the earphone 1012 and played. For example, the master earphone 1011 transmits the URL of the audio file or the audio data to the slave earphone 1012 through the second DLNA connection, and the slave earphone 1012 downloads the audio data from the DMS terminal 20 for playing.

In some embodiments, the address of the audio data in the second control instruction may be the same as or different from the address of the audio data contained in the first control instruction. In playing stereo audio data, the master earphone 1011 and the slave earphone 1012 may play together or cooperatively, for example, split-channel playing, etc., and thus the master earphone 1011 and the slave earphone 1012 may play the same or different audio data. In some embodiments, the audio data of each channel in the multi-channel audio data may have a channel identifier, the audio data of different channels may be stored at different addresses, or may be stored at the same address, and the master earphone 1011 and the slave earphone 1012 may download the audio data of the corresponding channel from different addresses, or download the audio data from the same address, and then select the playing based on the channel identifier. In some embodiments, other personalized configurations may be further included in the related information of the audio data, so as to implement personalized playing of multi-channel stereo audio, flexible configuration of playing scenes, and the like, which are not listed here.

In some embodiments, the master earpiece 1011 receives playback control commands for audio data from the smart device 102 using the first DLNA connection, while the master earpiece 1011 sends playback control commands for audio data to the slave earpiece 1012 using the second DLNA connection. The playing control instruction is any one of playing, pausing, volume adjusting, fast forwarding and fast rewinding, and a user can select or input the playing control instruction based on actual needs so as to meet the actual requirements of the user. For example, the application software on the smart device 102 may be used to send a command or control information related to a play control function of controlling play, pause, volume adjustment, fast forward, fast backward, and the like to the master earphone 1011 through the first DLNA connection, and the master earphone 1011 uses the second DLNA connection to send a play control command related to the slave earphone 1012 for execution, so as to implement synchronous control of audio play of the master earphone 1011 and the slave earphone 1012 and personalized regulation of parameters such as volumes of audio data of different channels, thereby better implementing synchronous play of multi-channel stereo audio and configuration of various scenes, and various application manners are not listed. For the slave headphone 1012, the control command or control information comes from the master headphone 1011, and the audio data comes from the DMS terminal 20; the slave earphone 1012 receives the control command or the control information by using the second DLNA connection, and acquires the audio data from the DMS terminal 20, so that the control command/control information is separated from the audio data, the protocol overhead is low during data sharing, and the audio data does not need to be forwarded to the slave earphone 1012 after the master earphone 1011 has completed receiving, thereby improving the efficiency of wireless transmission and shortening the overall time delay for the audio data to reach the two earphones.

According to the embodiment of the disclosure, the problems that most of music player software only supports connection of one DLNA device (for example, one wireless earphone in the disclosure) and causes low data transmission efficiency, unbalanced audio quality between the earphones and poor synchronism are solved, and the playing requirement of the stereo audio of the true wireless earphone can be better met.

In some embodiments, the DMS side may also be the smart device itself. Fig. 2 is a schematic diagram of a wireless audio playback system according to further embodiments of the present disclosure, in which the DMS end is a smart device 102. In some embodiments, the audio file or audio data may be stored locally on the smart device 102, in which case the smart device 102 is also a DMS side, and specifically, may be a Local digital media server (Local DMS), and the master headset 1011 and the slave headset 1012 may also access the audio file or audio data locally on the smart device 102 via the URL. Other parts of the wireless audio playing system 10 shown in fig. 2 are similar to those in fig. 1, for example, a first DLNA connection is established between the master earphone 1011 and the smart device 102, a second DLNA connection is established between the master earphone 1011 and the slave earphone 1012, and so on, which are not described herein again.

In the earphone assembly according to an embodiment of the present disclosure and the wireless audio playback system as shown in fig. 1 or 2, the first DLNA connection and the second DLNA connection may be established based on a WIFI channel or a bluetooth channel. The mobile phone, the master earphone and the slave earphone form a local area network by utilizing the WIFI hotspot, the local area network is independent of the specific form of the WIFI hotspot, for example, the local area network can be formed by an independent WIFI router and the mobile phone, the master earphone and the slave earphone and is not limited specifically.

In some embodiments, the handset, master and slave headsets may form a local area network using a bluetooth network. When first DLNA is connected and the WIFI network is utilized to realize with the connection of second DLNA, the true wireless earphone that uses the bluetooth to realize relatively can obtain better tone quality and with the farther transmission distance of smart machine and stronger interference killing feature.

In some embodiments, the wireless audio playing system comprises a headset pair consisting of any one of the pair of headsets and another other headset also supporting DLNA protocol in a headset assembly, and a smart device according to embodiments of the present disclosure. In the present disclosure, both of the earphones in the earphone assembly support the DLNA protocol, and may serve as DLNA devices, and the smart device also supports the DLNA protocol. The headset assembly according to the embodiment of the present disclosure establishes DLNA connection between two headsets, and between any one of the headsets (master headset) and the smart device, also based on the DLNA protocol. Thus, for example, when one of the paired earphones according to an embodiment of the present disclosure is damaged or lost, the other earphone may be paired with the other earphone supporting the DLNA protocol for use, regardless of whether the earphone is the same model or brand as the original paired earphone. In some embodiments, if the other earphones are limited in functionality although supporting the DLNA protocol, for example, a second DLNA connection cannot be established with another earphone while a first DLNA connection is established with the smartphone, then when stereo audio data playback is required, one of the original pair of earphones may be used as the master earphone, and the other earphones used for replacement may be used as the slave earphones. As such, the headset assembly according to embodiments of the present disclosure provides greater flexibility and convenience for the user to use.

Fig. 3 shows a flow diagram of a method of communication between a smart device and a headset assembly according to an embodiment of the disclosure. The communication method between a smart device and a headset assembly including a pair of headsets each supporting DLNA protocol as shown in fig. 3 begins at step S1 where one of the pair of headsets may be selected as a master headset and the other as a slave headset for the smart device. In some embodiments, the smart device may select one headset as the primary headset whenever it is found, according to the existing DLNA protocol of the smart device. In other embodiments, when the smart device can discover multiple DLNA devices at the same time, for example, two headsets, one of the headsets may be designated as a master headset by the user, or one headset may be selected as a master headset and the other headset may be selected as a slave headset by the smart device randomly or according to connection quality, and the specific determination manner of the master headset is not limited in this disclosure.

Step S2, a first DLNA connection may be established between the master earphone and the smart device based on a DLNA protocol, and the first DLNA connection may be used to receive a first control command from the smart device and execute the first control command. The smart device sends the address of the audio data over the first DLNA connection, the smart device may act as a DMC, the primary earpiece acts as a DMP, and the audio data is downloaded from the DMS and used for playback based on the address of the audio data received via the first DLNA connection. The intelligent device can also send playing control instructions such as playing, pausing, volume adjusting, fast forwarding, fast rewinding and the like of the audio data through the first DLNA connection, so that playing control, scene configuration and the like of the earphone assembly by the intelligent device are achieved.

Step S3, a second DLNA connection may be established between the master earphone and the slave earphone based on a DLNA protocol, and a second control command may be sent to the slave earphone by using the second DLNA connection. In some embodiments, the second control instruction includes an address of the audio data and/or a play control instruction of the audio data, and the specific content may include forwarding of related content in the first control instruction, or may be a related control instruction that the master earphone sends to the slave earphone according to the requirement of audio play, which is not limited in this disclosure.
