The following examples are illustrative of the present application, but are not intended to limit the scope of the present application.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing embodiments of the present application only and is not intended to be limiting of the present application.

In the following description, reference is made to "some embodiments" which describe a subset of all possible embodiments, but it is to be understood that "some embodiments" can be the same subset or different subsets of all possible embodiments and can be combined with one another without conflict.

It should be noted that the term "first/second/third" in reference to the embodiments of the present application is used to distinguish similar or different objects, and does not represent a specific ordering of the objects, it being understood that the "first/second/third" may be interchanged with a specific order or sequence, as permitted, to enable the embodiments of the present application described herein to be implemented in an order other than that illustrated or described herein.

It should be noted that the low-power audio transmission technology is a way to realize broadcast audio transmission, and it can work with lower power consumption to realize audio data transmission.

In the related art, in order to implement a low-power audio transmission technology, a broadcast source device and an audio playing device are generally required to be used, and audio data sent by the broadcast source device is received and played correspondingly based on the audio playing device.

For example: under the condition that the traditional Bluetooth earphone, the wired earphone and the like are used as audio playing equipment, the equipment cannot support a low-power-consumption audio transmission protocol, so that the equipment cannot directly communicate with broadcast source equipment, and cannot acquire audio data for playing in a low-power-consumption audio transmission mode.

In order to solve the above-mentioned problems in the related art, an audio transmission method is provided in the embodiments of the present application, and a practical application scenario of the audio transmission method is explained below.

Fig. 1 is a schematic view of an application scenario of an audio transmission method provided in an embodiment of the present application, please refer to fig. 1, and the scenario includes: broadcast source device 110, terminal device 120, and audio playback device 130.

The broadcast source device 110 may be a mobile phone with broadcasting capability, a signal initiating device, or any electronic device with a broadcast transmitting function, through which audio data may be transmitted in a broadcast form.

The terminal device 120 may be a mobile phone including, but not limited to, a mobile phone, a wearable device (e.g., smart watch, smart bracelet, smart glasses, etc.), a tablet computer, a notebook computer, a vehicle-mounted terminal, a PC (Personal Computer ), etc. The functions performed by the method may be performed by a processor in the relay device calling program code, which of course may be stored in a computer storage medium, it being seen that the relay device comprises at least a processor and a storage medium.

The audio playback device 130 may be, for example, a speaker, a headphone, or any device having audio output capabilities, without specific limitation.

It should be noted that, communication may be performed between the broadcast source device 110 and the terminal device 120 in a broadcast manner, that is, the broadcast source device 110 transmits data in a broadcast manner, and the terminal device 120 receives corresponding data.

The terminal device 120 and the audio playing device 130 may communicate with each other by a wired connection or a bluetooth connection, and it should be noted that, the audio playing device is a device that does not support broadcast communication with the broadcast source device.

The implementation process of the audio transmission method provided in the embodiment of the present application is explained below based on the above-mentioned practical application scenario.

Fig. 2 is a flowchart of an audio transmission method provided in an embodiment of the present application, please refer to fig. 2, the method includes:

s210: a broadcast signal of a broadcast source device is acquired.

Wherein the broadcast signal includes target audio data.

It should be noted that the main implementation body of the method may be the terminal device, and the terminal device may acquire a broadcast signal of the broadcast source device, where the broadcast signal may include target audio data sent by the broadcast source device, where the target audio data may be, for example, music, a recording, or any information that may be transmitted as audio data, and is not limited herein.

Wherein the broadcast source device may transmit a broadcast signal in the form of a broadcast, and the terminal device may receive the broadcast signal in a specific reception state, thereby acquiring the target audio data.

S220: and sending the target audio data to an audio playing device which establishes communication connection so as to play the target audio data through the audio playing device.

Wherein the audio playback device does not support broadcast communication with the broadcast source device.

It should be noted that, after the target audio data is obtained, the target audio data may be sent to the audio playing device. The audio playing device may be, for example, a wired earphone, or a conventional bluetooth earphone without broadcast receiving capability, or the like.

For wired headphones, the target audio data may be sent to the audio playing device by way of a physical line; for a conventional bluetooth headset without broadcast receiving capability, the target audio data may be transmitted to the audio playback device by means of bluetooth communication.

Because the audio playing device does not support the broadcast communication with the broadcast source device, the audio playing device cannot directly receive the broadcast signal sent by the broadcast source device, and the target audio data needs to be acquired after forwarding through the terminal device.

In the audio transmission method provided by the embodiment of the application, a broadcast signal of a broadcast source device can be obtained, wherein the broadcast signal comprises target audio data; and sending the target audio data to an audio playing device which establishes communication connection so as to play the target audio data through the audio playing device, wherein the audio playing device does not support broadcast communication with the broadcast source device. The terminal equipment acquires the broadcast signal of the broadcast source equipment, and the terminal equipment transmits the broadcast signal in a communication mode between the terminal equipment and the audio playing equipment, so that the audio playing equipment can receive corresponding audio information, corresponding audio playing is realized, and the universality of broadcast communication is improved.

The implementation procedure of determining the broadcast source apparatus based on the terminal apparatus provided in the embodiment of the present application is explained below.

Fig. 3 is another flow chart of an audio transmission method provided in an embodiment of the present application, referring to fig. 3, before acquiring a broadcast signal of a broadcast source device, the method includes:

s310: a target broadcast source is determined from the at least one broadcast source.

In the actual application scenario, the same terminal device may receive broadcast signals sent by multiple broadcast sources.

For example: in the case where two broadcast sources exist in one area, the terminal device may receive broadcast information of the two broadcast sources, but in the case where the terminal device transmits target audio data to the audio playback device, the target audio data in the broadcast information transmitted by one of the broadcast sources may be required.

On the basis, one of the broadcast sources may be determined from among the plurality of broadcast sources as the target broadcast source.

Correspondingly, acquiring the broadcast signal of the broadcast source device includes:

s320: target audio data is acquired from a target broadcast source by means of broadcast reception.

The broadcast receiving manner may be to receive the broadcast message according to a corresponding receiving frequency, for example: the receiving frequency of the first broadcast source is frequency a, and the receiving frequency of the second broadcast source is frequency B, and if the broadcast information of the first broadcast source needs to be received, the receiving frequency a can be used as the receiving frequency to receive, thereby obtaining the corresponding broadcast signal.

After the broadcast signals are acquired through the corresponding broadcast receiving mode, corresponding target audio data can be determined, and then the target audio data are sent to corresponding audio playing equipment to realize the output of the audio data.

In the audio transmission method provided by the embodiment of the application, a target broadcast source can be determined from at least one broadcast source; target audio data is acquired from a target broadcast source by means of broadcast reception. The method can more accurately receive the broadcast signal by determining the target broadcast source, avoid error propagation of the broadcast signal, and further obtain more accurate target audio data to be sent to the audio playing device.

The following explains a specific implementation procedure for determining a target broadcast source provided in the embodiment of the present application.

Fig. 4 is another flow chart of an audio transmission method provided in an embodiment of the present application, referring to fig. 4, before determining a target broadcast source from at least one broadcast source, the method includes:

s410: broadcast source information is acquired and a broadcast source list is established based on the broadcast source information.

Wherein the broadcast source list includes at least one broadcast source.

It should be noted that, before determining the target broadcast source, the broadcast source information may be acquired by a manner of detection of the terminal device itself, for example: the source of the broadcast signals which can be received by the terminal equipment can be determined in a detection mode, if the terminal equipment can receive N broadcast signals in a broadcast mode, the terminal equipment can be determined to acquire the signals sent by the N broadcast sources, and the information of the broadcast sources can be acquired respectively.

The information of the broadcast source may be, for example, a receiving frequency of a broadcast signal transmitted by the broadcast source, a signal strength of the broadcast signal, etc., which are not particularly limited herein, and any relevant information that may be used to represent the broadcast source may be obtained as one of the broadcast source information based on actual requirements.

After the broadcast source information of the plurality of broadcast sources is obtained respectively, a broadcast source list can be established based on the broadcast source information, and the plurality of broadcast sources and the corresponding broadcast source information thereof can be recorded in the broadcast source list, wherein the broadcast sources can be broadcast sources which can receive broadcast signals by the terminal equipment.

It should be noted that, based on the above manner, a plurality of broadcast sources may be established to obtain a broadcast source list, and based on the broadcast source list, a subsequent target broadcast source determination task may be performed.

Accordingly, determining a target broadcast source from the at least one broadcast source includes:

s420: a target broadcast source is determined from the broadcast source list.

After the broadcast source list is obtained, one of the broadcast sources may be set as a target broadcast source from the broadcast source list. Wherein the at least one broadcast source comprises the target broadcast source.

The target broadcast source may be determined from the broadcast source list, or if a new broadcast source is temporarily added by the user, if the new broadcast source is used as the target broadcast source, the broadcast source information of the new broadcast source may be stored in the broadcast source list by the terminal device.

In the audio transmission method provided by the embodiment of the application, broadcast source information can be acquired, and a broadcast source list is established based on the broadcast source information; a target broadcast source is determined from the broadcast source list. By establishing the broadcast source list, the target broadcast source can be determined more quickly and accurately, so that broadcast signals sent by the target broadcast source can be received more efficiently, and corresponding target audio data can be determined.

The method for determining the target broadcast source from the broadcast source list may be various, and a process for determining the target broadcast source in various ways will be explained below.

In one embodiment, determining a target broadcast source from a broadcast source list includes: in response to the selection operation, a target broadcast source is determined from the broadcast source list.

It should be noted that the terminal device may be a mobile phone or other types of devices with display interfaces, where a list of broadcast sources may be displayed in the corresponding display interface of the device, for example, a name of each broadcast source and corresponding broadcast source information may be displayed in a list manner.

The target broadcast source may be determined from the broadcast source list based on a user selection operation, for example: if the broadcast source list includes N broadcast sources, a corresponding selection control may exist based on the N broadcast sources, and the user may select one of the broadcast sources as the target broadcast source through the selection control.

In another embodiment, determining a target broadcast source from a broadcast source list includes: determining identification information of each broadcast source in a broadcast source list; and under the condition that the identification information of the broadcast source is the same as the preset identification information, determining the broadcast source as a target broadcast source.

It should be noted that, a preset identification information may be configured in advance in the terminal device, where the preset identification information may be used to indicate identification information of a required broadcast source, after the broadcast source list is obtained, since the broadcast source list may include broadcast source information, these information may include identification information of the broadcast source, and the broadcast source may be compared with the preset identification information based on the identification information of each broadcast source, if the broadcast source is the required broadcast source, the corresponding broadcast source may be used as the target broadcast source; in contrast, if the broadcast source is different, the broadcast source may be determined to be an unnecessary broadcast source, and the corresponding determination may be performed based on the next broadcast source in the broadcast source list until the target broadcast source is determined or all the broadcast sources in the list cannot be used as the target broadcast source.

The identification information may be a name of a broadcast source or a reception frequency, etc., and is not particularly limited herein. If there are a plurality of broadcast sources that can be targeted broadcast sources in the broadcast source list, one of the broadcast sources may be targeted broadcast sources in order.

In one embodiment, determining a target broadcast source from a broadcast source list includes: determining the signal intensity of each broadcast source in the broadcast source list; and taking the broadcast source with the highest signal strength as a target broadcast source.

It should be noted that, in the actual implementation process, there may be a scenario where there is no hard requirement on the specific content broadcast by the broadcast source, for example: when any one of the broadcast sources is selected as the target broadcast source, in order to ensure normal transmission of the broadcast signals, the signal strength of the broadcast source can be used as a standard, and the broadcast source with high signal strength can be used as the target broadcast source.

The signal intensity of each broadcast source can be recorded in the broadcast source list, and in the process of determining the target broadcast source, the broadcast source with the highest signal intensity in the broadcast source list can be used as the target broadcast source.

In addition to the above three manners of determining the target broadcast source from the broadcast source list, the transmission of the audio signal may be achieved by selecting the desired broadcast source from the broadcast source list as the target broadcast source according to the actual application scenario, which is not particularly limited herein.

The following explains a specific implementation procedure implemented by bluetooth transmission in the audio transmission method provided in the embodiment of the present application.

Fig. 5 is another flow chart of an audio transmission method provided in an embodiment of the present application, please refer to fig. 5, for sending target audio data to an audio playing device for establishing a communication connection, which includes:

s510: in the case where the communication connection is a bluetooth communication connection, the format of the target audio data is converted into an audio stream format supporting bluetooth transmission.

It should be noted that, the initial format of the target audio data received by the terminal device may be a format of a broadcast audio stream, and the audio stream in the format may be converted into an audio stream format supporting bluetooth transmission.

The above format conversion may be performed on the premise that the communication connection is determined to be a bluetooth connection, so as to obtain the target audio data in the audio stream format supporting bluetooth transmission.

In the actual conversion process, a corresponding conversion mode may be preconfigured in the terminal device, for example: the conversion of the two audio stream formats can be realized by a pre-configured conversion mode in the terminal equipment, so that the audio stream format supported by Bluetooth transmission is obtained.

The audio stream format supported by bluetooth transmission may be, for example, an audio stream in the format of a2dp (Advanced Audio Distribution Profile, bluetooth audio transmission model agreement).

S520: and transmitting the target audio data to the audio playing device through the Bluetooth communication connection.

It should be noted that, after converting the format of the target audio data, determining whether the audio playing device is in the bluetooth receiving mode, if so, transmitting the target audio data to the audio playing device in a bluetooth transmission mode.

The bluetooth reception mode may be, for example, a mode in which an acl connection (Asynchronous Connection Link) is established between the terminal device and the audio playback device, and it is determined that the audio playback device is in a br (basic rate) mode, in which the audio playback device may receive the target audio data after format conversion.

In addition, except for the case of bluetooth transmission, if the audio playing device is a wired earphone, the terminal device can directly transmit the target audio data to the wired earphone through the corresponding physical line in a bluetooth transmission mode, and the earphone plays the corresponding target audio data.

In the audio transmission method provided by the embodiment of the application, the format of the target audio data can be converted into the audio stream format supported by Bluetooth transmission; and under the condition that the audio playing device is in the Bluetooth receiving mode, transmitting the target audio data to the audio playing device in a Bluetooth transmission mode. The method comprises the steps that through format conversion, the audio playing device can receive target audio data sent by the broadcast source device, and accordingly the audio source device can play the corresponding target audio data.

It should be noted that, in the implementation process, there may be a cause such as a failure of the broadcast source, so as to ensure that the audio playing device can play the target audio data normally, the broadcast source may be switched and selected, and one possible switching manner is explained below.

In one embodiment, after the target audio data is sent to the audio playing device communicatively connected to the terminal device, the method further includes: determining the signal strength of a current broadcast source; and switching the broadcasting source under the condition that the signal intensity of the current broadcasting source is lower than a preset signal intensity threshold value.

It should be noted that, the signal strength of the broadcast source may be obtained in real time by the terminal device, and a preset signal strength threshold may be preconfigured, where the preset signal strength threshold may be set correspondingly according to the actual requirement, and is not limited by a specific numerical value.

Under the condition that the signal intensity of the current broadcast source is lower than a preset signal intensity threshold value, it can be determined that the currently used broadcast source is unstable, and the situation that signal packet loss and the like possibly exist when the broadcast signal is continuously acquired based on the current broadcast source can be avoided, and the broadcast source can be switched.

Accordingly, if the signal strength of the current broadcast source is not lower than the preset signal strength threshold, it can be determined that the currently used broadcast source is stable, and the situation that signal packet loss and the like cannot occur due to the fact that the broadcast signal is continuously acquired based on the current broadcast source does not need to be switched.

The signal strength may be calculated by packet loss rate or other related data, for example: the farther the terminal device is from the broadcast source, the lower the signal strength; the more interference signals that are present around, the lower the signal strength.

The following explains the implementation process of switching the current broadcast source to other broadcast sources in the process of implementing the broadcast source switching.

In one embodiment, switching the broadcast source in the case that the signal strength of the broadcast source is lower than a preset signal strength threshold value includes: determining at least one associated broadcast source of the same type as the current broadcast source; and under the condition that the signal intensity of the current broadcast source is lower than a preset signal intensity threshold value, switching the current broadcast source into an associated broadcast source of the current broadcast source.

It should be noted that at least one associated broadcast source of the same type as the current broadcast source may be determined, where the broadcast source type may be determined by information of the broadcast source, and the associated broadcast source may be determined based on the broadcast source list described above.

For example: and traversing the information of all the broadcast sources in the broadcast source list, and taking the broadcast source B as an associated broadcast source if the current broadcast source is the broadcast source A and the broadcast source B is the same as the broadcast source A.

It should be noted that the broadcast sources may be the same or similar in type, or the broadcast sources may be the same or similar in frequency, which is not particularly limited herein, and may be represented by a certain association relationship between the broadcast sources, and the associated broadcast sources are determined based on the association relationship.

Wherein, the associated broadcast source can be one or a plurality of broadcast sources.

In addition, besides determining the associated broadcast source in the above manner, one or more broadcast sources may be obtained as the associated broadcast source through active setting by the user or automatic detection by the terminal device based on the broadcast source information.

After determining the associated broadcast source, the current broadcast source may be switched to the associated broadcast source of the current broadcast source if the signal strength of the current broadcast source is below a preset signal strength threshold.

For example, if the broadcast source a is a current broadcast source and the broadcast source B is an associated broadcast source of the broadcast source a, the current broadcast source may be switched to the broadcast source B if the signal strength of the broadcast source a is lower than a preset signal strength threshold.

The above-mentioned process is a process of switching broadcast sources based on the terminal device itself, and in the actual implementation process, the corresponding switching may be performed by a user operation manner, which is not limited herein.

The following explains the interaction among the broadcast source device, the terminal device, and the audio playing device in the embodiments of the present application.

Fig. 6 is an overall interaction schematic diagram of an audio transmission method provided in an embodiment of the present application, referring to fig. 6, the interaction step includes interaction between a broadcast source device and a terminal device and interaction between the terminal device and an audio playing device, where, according to an execution sequence, the interaction between the broadcast source device and the terminal device may include:

determining, by the broadcast source device, a manner of transmitting the broadcast signal, for example, determining whether to delay transmission or to transmit at a fixed time, and determining, by the broadcast source device, target audio data to be transmitted; in addition, determining a storage space of the target audio data in the broadcast signal and establishing a data path of the target audio data; the broadcast signal is transmitted by the broadcast source device to the terminal device.

In order of execution, the interaction between the terminal device and the audio playback device may include:

establishing acl connection and determining that the audio playing device is in br mode; the terminal equipment sends a Bluetooth transmission request to the audio playing equipment, and the audio playing equipment returns a request result to the terminal equipment; and sending the target audio data to the audio playing device by the terminal device.

The audio playback device may play the target audio data after receiving the target audio data.
