Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

With the development of wireless communication technology, more audio playing devices can establish a connection with electronic devices in a wireless communication manner, so that the electronic devices can transmit audio data to be played to the audio playing devices for playing through the connection. For example, taking the audio playing device as a wireless earphone, taking the electronic device as a smart phone as an example, the smart phone can establish connection with the wireless earphone in a wireless communication manner, and output audio data to be played to the wireless earphone for playing.

In some cases, audio data to be played by an electronic device may be played collectively by a plurality of audio playback devices. However, in the related manner, there is also a problem that the playback of the audio data to be played back by the electronic device is not synchronized enough by the plurality of audio plays. For example, electronic devices typically establish a connection with an audio playback device in response to a broadcast signal sent by the audio playback device. However, in the case of a plurality of audio playing devices, the electronic device usually establishes connection with the plurality of audio playing devices in sequence, and the audio playing devices can acquire the audio data to be played by the electronic device through the established connection after establishing connection with the electronic device, so that the plurality of audio playing devices cannot acquire the audio data to be played by the electronic device more synchronously, and further, the plurality of audio playing devices cannot play the audio data to be played by the electronic device more synchronously.

Therefore, in order to improve the above-mentioned problem, the present inventors propose an audio data output method, an audio data output device, an audio playing device, and an audio playing device, wherein after a broadcast signal is sent by a first audio playing device, the first audio playing device may receive audio data sent by an electronic device through a connection with the electronic device, and play the received audio data. Furthermore, the first audio playing device may enable the second audio playing device to obtain the audio data transmitted to the first audio playing device by the electronic device through the connection between the first audio playing device and the electronic device until the electronic device establishes a connection with the electronic device in response to the broadcast signal sent by the second audio playing device.

Therefore, before the second audio playing device establishes connection with the electronic device, the second audio playing device can acquire the audio data output by the electronic device through the connection established between the first audio playing device and the electronic device, and play the audio data. So that the first audio playing device and the second audio playing device can play the audio transmitted by the electronic device more synchronously.

An application scenario according to an embodiment of the present application is described below.

As shown in fig. 1, an application scenario according to an embodiment of the present application includes an electronic device 100 and a storage box 200. Wherein, the storage box 200 is configured with a first audio playing device 210 and a second audio playing device 220. When the storage box 200 transitions from the state shown in fig. 1 to the state shown in fig. 2, the first audio playing device 210 and the second audio playing device 220 may each start to transmit a broadcast signal, and the electronic device 100 may establish a connection with the first audio playing device 210 and the second audio playing device 220 in response to the broadcast signals transmitted by the first audio playing device 210 and the second audio playing device 220, respectively.

Optionally, the broadcast signal sent by the first Audio playing device is LE Audio broadcast, the broadcast signal sent by the second Audio playing device is LE Audio broadcast, the connection established between the first Audio playing device and the electronic device is LE Audio connection, and the connection established between the second Audio playing device and the electronic device is LE Audio connection.

It should be noted that the first audio playing device 210 and the second audio playing device 220 shown in fig. 2 may be understood as a pair of TWS (True Wireless Stereo) headphones. In the embodiment of the present application, the first audio playing device and the second audio playing device may be other than those shown in fig. 2, for example, the first audio playing device and the second audio playing device may be sound boxes.

Embodiments of the present application will be described in detail below with reference to the accompanying drawings.

Referring to fig. 3, an audio data output method provided by an embodiment of the present application is applied to an audio playing device, where the audio playing device includes a first audio playing device and a second audio playing device, and the method includes:

s110: after the first audio playing device sends a broadcast signal, the first audio playing device receives audio data sent by the electronic device through a first communication link with the electronic device and plays the received audio data, wherein the first communication link is established by the electronic device in response to the broadcast signal sent by the first audio playing device.

In the embodiment of the application, the first audio playing device and the second audio playing device can start to send the broadcast signal for the electronic device to respond after being started, so that the electronic device can find the first audio playing device and the second audio playing device through the broadcast signal. After the electronic device discovers the first audio playing device through the broadcast signal sent by the first audio playing device, a first communication link can be established with the first audio playing device in response to the broadcast signal. Correspondingly, after the electronic device discovers the second audio playing device through the broadcast signal sent by the second audio playing device, a second communication link can be established with the second audio playing device in response to the broadcast signal.

The manner of starting corresponding to the first audio playing device and the second audio playing device in different embodiments may be different. Alternatively, if the first audio playing device and the second audio playing device are wireless headphones that can be placed in the storage box as shown in fig. 1 and 2, the first audio playing device and the second audio playing device are characterized to be started after the cover of the storage box is opened. Furthermore, optionally, the first audio playing device is a sound box, and the second audio playing device is a sound box, in which mode, the first audio playing device is activated when in an energized state, and correspondingly, the second audio playing device is activated when in an energized state.

Wherein, the communication link established between the electronic device and the first audio playing device and the second audio playing device can be established based on the corresponding communication protocol. Optionally, if the broadcast signal sent by the first Audio playing device is LE Audio broadcast and the broadcast signal sent by the second Audio playing device is LE Audio broadcast, then correspondingly, the first communication link established between the first Audio playing device and the electronic device is established based on the LE Audio protocol, and the second communication link established between the second Audio playing device and the electronic device is established based on the LE Audio protocol.

In one approach, the electronic device has begun to play audio before the first and second audio playback devices begin transmitting broadcast signals, except that the played audio is played through speakers configured by the electronic device itself. After the electronic device establishes a first communication link with the first audio playing device, the electronic device may transmit audio data to be played to the first audio playing device through the first communication link, so that the audio data to be played by the electronic device may be played by the first audio playing device.

It should be noted that, in one manner, after the electronic device establishes a connection (for example, a first communication link) with an external audio playing device (for example, a first audio playing device in the embodiment of the present application), if another external audio playing device is scanned again and there is no association between the other external audio playing device and the connected audio playing device, the electronic device may not establish a communication link with the other external audio playing device. Therefore, in the embodiment of the application, the first audio playing device and the second audio playing device may have an association relationship, so that after the electronic device first establishes a connection with the first audio playing device, the electronic device will establish a connection with the second audio playing device when the second audio playing device is scanned and the second audio playing device and the first audio playing device are identified to have an association relationship.

The association relationship between the first audio playing device and the second audio playing device may be understood that the first audio playing device and the second audio playing device correspond to the same device identifier. For example, the first audio playback device having the association relationship corresponds to the second audio playback device with the same combination identification resolution value SIRK (Set Identity Resolving Key).

S120: the second audio playing device acquires the audio data transmitted to the first audio playing device by the electronic device based on the first communication link to play.

The second audio playing device obtains audio data transmitted to the first audio playing device by the electronic device through connection between the first audio playing device and the electronic device, which can be understood as that the second audio playing device obtains audio data transmitted to the first audio playing device by the electronic device through link information corresponding to a first communication link between the first audio playing device and the electronic device, and can also be understood as that the second audio playing device directly obtains the audio data forwarded by the first audio playing device from the first audio playing device.

As one way, in order to facilitate the first audio playback device to timely transmit link information or transmit audio data to the second audio playback device, the first audio playback device and the second audio playback device may establish a connection with each other before transmitting a broadcast signal for establishing a connection with the electronic device. For example, after the first Audio playing device and the second Audio playing device are started, a connection may be established based on the classical bluetooth protocol, and then the first Audio playing device and the second Audio playing device start to send LE Audio broadcast. Furthermore, the connection between the first Audio playing device and the second Audio playing device can also be established based on the LE Audio mode.

S130: the second audio playing device responds to the second audio playing device to establish a second communication link with the electronic device, and audio data used for playing are replaced by audio data received based on the second communication link.

After a second communication link is established between the second audio playing device and the electronic device, the second audio playing device may directly acquire the audio data transmitted by the electronic device through the second communication link. Wherein the second audio playback device establishing the second communication link with the electronic device in response to the second audio playback device may be understood as the second audio playback device determining that it has established itself a second communication link with the device, or may be understood as after the second audio playback device has established a second communication link with the electronic device. Furthermore, the second audio playing device may change the audio data for playing to the audio data received based on the second communication link, which may be understood that the second audio playing device may not acquire the audio data transmitted to the first audio playing device by the electronic device based on the first communication link, but directly play the audio data received based on the second communication link, or may be understood that the second audio playing device may still acquire the audio data transmitted to the first audio playing device by the electronic device based on the first communication link, but may not play the audio data acquired based on the first communication link, but rather play the audio data received based on the second communication link.

In one manner, in the embodiment of the present application, the first audio playing device and the second audio playing device may also negotiate a start playing time, where the start playing time is used for playing the audio data transmitted by the electronic device in synchronization with the first audio playing device and the second audio playing device. In this manner, after the first audio playing device transmits the broadcast signal, the first audio playing device may receive the audio data transmitted by the electronic device through the first communication link with the electronic device, and start playing the received audio data based on the start playing time negotiated with the second audio playing device. Correspondingly, after the second audio playing device obtains the audio data transmitted to the first audio playing device by the electronic device based on the first communication link, the second audio playing device starts playing the received audio data based on the starting playing time.

According to the audio data output method provided by the embodiment, after the first audio playing device sends the broadcast signal, the first audio playing device can receive the audio data sent by the electronic device through the first communication link between the first audio playing device and the electronic device, and play the received audio data. Furthermore, the second audio playing device obtains the audio data transmitted to the first audio playing device by the electronic device through a first communication link between the first audio playing device and the electronic device, and plays the audio data until the electronic device responds to a broadcast signal sent by the second audio playing device to establish connection with the second audio playing device. Therefore, before the second audio playing device establishes connection with the electronic device, the second audio playing device can acquire the audio data output by the electronic device through the connection established between the first audio playing device and the electronic device, and play the audio data. So that the first audio playing device and the second audio playing device can play the audio transmitted by the electronic device more synchronously.

Referring to fig. 4, an audio data output method provided by an embodiment of the present application is applied to an audio playing apparatus, where the audio playing apparatus includes a first audio playing device and a second audio playing device, and the method includes:

s210: after the first audio playing device sends a broadcast signal, the first audio playing device receives audio data sent by the electronic device through a first communication link with the electronic device and plays the received audio data, wherein the first communication link is established by the electronic device in response to the broadcast signal sent by the first audio playing device.

S220: the first audio playing device sends the link information of the first communication link to the second audio playing device.

The first communication link established between the first audio playing device and the electronic device is established in a wireless communication mode. Therefore, the wireless frequency band is used as a transmission channel between the electronic device and the first audio playing device to transmit the audio data. Optionally, the link information of the first communication link established by the electronic device and the first audio playing device may include a radio frequency band used for audio data transmission between the electronic device and the first audio playing device and a corresponding key. The second audio playing device can monitor the used radio frequency band, and then process the monitored transmission data based on the secret key, so as to obtain the audio data transmitted to the first audio playing device by the electronic device. In this way, after the second audio playing device obtains the link information, the second audio playing device can directly monitor the corresponding radio frequency band to obtain the audio data, so that the second audio playing device can obtain the audio data transmitted by the electronic device relatively synchronously with the first audio playing device.

It should be noted that, in one manner, the order in which the plurality of audio devices having the association relationship establish the communication link with the electronic device may be configured. In this manner, an audio playback device configured to previously establish a communication link with an electronic device may default to transmitting link information to other associated audio playback devices or forwarding audio data sent by the electronic device, so that the other associated audio playback devices may also have audio data to play before themselves establish a communication link with the electronic device. For example, in the embodiment of the present application, the first audio playing device is configured to establish a communication link with the electronic device before, and the second audio playing device is configured to establish a communication link with the electronic device after.

In another manner, the order in which the plurality of audio devices having the association relationship establish the communication link with the electronic device may not be configured. In this manner, the audio playback device that establishes a communication link with the electronic device may detect whether it is necessary to transmit link information to other audio playback devices associated therewith or to forward audio data sent by the electronic device. Optionally, an audio playback device (e.g., a first audio playback device) that has established a communication link with the electronic device may detect whether link information transmitted by other audio playback devices is stored; and if no link information is transmitted by other audio playing equipment, the link information of the first communication link is sent to the second audio playing equipment.

Under the condition that the first audio playing device detects that the link information transmitted by other audio playing devices is not stored, the first audio playing device can be determined to establish a communication link with the electronic device before the second audio playing device, and in order to facilitate the second audio playing device which can establish the communication link with the electronic device later to play with the first audio playing device more synchronously, the second audio playing device can acquire the audio data transmitted to the first audio playing device by the electronic device through the first communication link between the first audio playing device and the electronic device. Alternatively, the stored link information may be deleted after the first audio playback device or the second audio playback device is turned off. For example, if the first audio playing device and the second audio playing device are wireless headphones that can be placed in the same storage box, after the first audio playing device and the second audio playing device are placed in the storage box and the storage box closes the box cover, it is determined that the first audio playing device or the second audio playing device is closed. For another example, if the first audio playing device and the second audio playing device are speakers, if the first audio playing device and the second audio playing device are powered on, it is determined that the first audio playing device or the second audio playing device is turned off.

S230: the second audio playing device monitors the first communication link based on the link information of the first communication link to acquire audio data transmitted to the first audio playing device by the electronic device for playing.

After the second audio playing device acquires the link information of the first communication link, the second audio playing device can start to monitor the first communication link.

S240: and the second audio playing device responds to the second audio playing device to establish a second communication link with the electronic device, and stops monitoring the first communication link.

S250: the second audio playing device receives the audio data sent by the electronic device based on the second communication link and plays the received audio data.

According to the audio data output method provided by the embodiment, before the second audio playing device is connected with the electronic device, the audio data output by the electronic device can be obtained through the connection between the first audio playing device and the electronic device, and the audio data are played. So that the first audio playing device and the second audio playing device can play the audio transmitted by the electronic device more synchronously. In addition, in this embodiment, the first audio playing device may send the link information between the first audio playing device and the electronic device to the second audio playing device, so that the second audio playing device may directly obtain the audio data output by the electronic device through a listening manner, which is favorable for enabling the second audio playing device to better synchronize with the first audio playing device to play the audio data transmitted by the electronic device.

Referring to fig. 5, an audio data output method provided by an embodiment of the present application is applied to an audio playing apparatus, where the audio playing apparatus includes a first audio playing device and a second audio playing device, and the method includes:

s310: after the first audio playing device sends a broadcast signal, the first audio playing device receives audio data sent by the electronic device through a first communication link with the electronic device and plays the received audio data, wherein the first communication link is established by the electronic device in response to the broadcast signal sent by the first audio playing device.

S320: the first audio playing device transmits the audio data transmitted by the electronic device through the first communication link to the second audio playing device through the communication link between the first audio playing device and the second audio playing device, so that the audio data is played by the second audio playing device.

As one way, the connection may be established with each other before the first audio playback device and the second audio playback device each start transmitting the broadcast signal. In this way, the first audio playing device may then retransmit the audio data transmitted from the electronic device to the second audio playing device based on the connection established in advance with the second audio playing device.

S330: and the second audio playing device responds to the second communication link established between the second audio playing device and the electronic device, and sends a request for stopping sending audio data to the first audio playing device.

In the case that the second audio playing device has established the second communication link with the electronic device, it is characterized that the second audio playing device may have directly obtained the audio data to be played by the electronic device from the electronic device, and therefore, a request for stopping sending the audio data may be sent to the first audio playing device. After receiving the request for stopping sending the audio data, the first audio playing device will not send the audio data acquired from the first communication link to the second audio playing device.

S340: the second audio playing device receives the audio data sent by the electronic device based on the second communication link and plays the received audio data.

In some modes, a plurality of audio playing devices with association relations can play audio data of different channels simultaneously, so that a user can have better stereo experience. For example, one audio playback device may play left channel audio data and another audio playback device may play right channel audio data, thereby providing a better stereo experience for the user. In some cases, the audio data to be played by the electronic device may be mono audio data or may be multi-channel audio data. In one mode, if the audio data sent to the first audio playing device by the electronic device includes first channel audio data and second channel audio data, the first audio playing device receives the audio data sent by the electronic device and plays the first channel audio data, and then the second channel audio data is transmitted to the second audio playing device for playing.

Correspondingly, in this manner, the electronic device may transmit the first channel audio data and the second channel audio data to the audio playing device that has already been connected currently when detecting that only one audio playing device has been connected, and transmit the first channel audio data to one audio playing device and the first channel audio data to the other audio playing device when detecting that another audio playing device has been connected.

According to the audio data output method provided by the embodiment, before the second audio playing device is connected with the electronic device, the audio data output by the electronic device can be obtained through the connection between the first audio playing device and the electronic device, and the audio data are played. So that the first audio playing device and the second audio playing device can play the audio transmitted by the electronic device more synchronously. In addition, in this embodiment, the first audio playing device may forward the audio data transmitted from the electronic device to the second audio playing device for playing, so that the first audio playing device and the second audio playing device may play the audio transmitted from the electronic device more synchronously.

Furthermore, in this embodiment, when the audio data output by the electronic device includes the left channel audio data and the right channel audio data, the electronic device may output both the left channel audio data and the right channel audio data to the first audio playing device, so that the first audio playing device may play the first channel audio data, and then transmit the second channel audio data to the second audio playing device for playing, so that the first audio playing device and the second audio playing device may play the audio transmitted by the electronic device more synchronously, and also make the played audio data have better stereo experience.

Referring to fig. 6, an audio data output method provided by an embodiment of the present application is applied to a first audio playing device, where the first audio playing device is associated with a second audio playing device, and the method includes:

s410: after the first audio playing device sends a broadcast signal, the first audio playing device receives audio data sent by the electronic device through a first communication link with the electronic device and plays the received audio data, wherein the first communication link is established based on the broadcast signal sent by the electronic device in response to the first audio playing device.

S420: and enabling the second audio playing device to acquire the audio data transmitted to the first audio playing device by the electronic device based on a first communication link between the first audio playing device and the electronic device, and playing until the electronic device responds to a broadcast signal sent by the second audio playing device to establish a second communication link with the second audio playing device.

According to the audio data output method provided by the embodiment, before the second audio playing device is connected with the electronic device, the audio data output by the electronic device can be obtained through the connection between the first audio playing device and the electronic device, and the audio data are played. So that the first audio playing device and the second audio playing device can play the audio transmitted by the electronic device more synchronously.

Referring to fig. 7, an audio data output method provided by an embodiment of the present application is applied to a second audio playing device, where the second audio playing device is associated with a first audio playing device, and the method includes:

s510: after the first audio playing device and the second audio playing device respectively send broadcast signals, the second audio playing device obtains audio data transmitted to the first audio playing device by the electronic device through a first communication link between the first audio playing device and the electronic device, and plays the audio data.

S520: in response to the second audio playback device establishing a second communication link with the electronic device, the second audio playback device exchanges audio data for playback with audio data received based on the second communication link.
