In this embodiment, it should be noted that, considering the low latency requirement of the user in the bluetooth transmission process, the mobile phone is connected to the bluetooth headset to implement the low latency sound effect, and the bluetooth packet sending interval parameter and the packet sending size need to be adjusted to implement the low latency of the sound. The current mobile phone mostly adopts the scheme of ADSP (advanced digital signal processing), and because ADSP belongs to a hard coding scheme, parameter setting is difficult, so that the prior art cannot conveniently adjust the Bluetooth packet transmission interval parameter and the packet transmission size. The soft coding is to directly deliver the audio data to the bluetooth protocol stack, the audio data is coded by the bluetooth protocol stack, and then the audio data is transmitted by the bluetooth without being processed by the chip of the ADSP, so that all parameters such as packet transmission intervals, packet transmission sizes, coding modes and the like can be subjected to parameter adjustment by the bluetooth protocol stack, but the problem caused by the soft coding is high power consumption. Therefore, in this embodiment, the two usage scenarios are fused, and the current bluetooth audio transmission mode is adaptively determined, so that power consumption and resource consumption of bluetooth audio transmission are reduced under the condition of low delay requirement, and delay of bluetooth audio transmission is reduced under the condition of high delay requirement, so that user experience is enhanced.

EXAMPLE five
Fig. 7 is a flowchart of a fifth embodiment of a bluetooth audio control method according to the present invention, based on the foregoing embodiments, in order to further determine that if the delay requirement is lower than the preset delay value, the audio to be transmitted is subjected to soft coding processing and transmitted through a bluetooth protocol stack, and if the delay requirement is higher than the preset delay value, the audio to be transmitted is subjected to hard coding processing and transmitted through a processor, in this embodiment:
s41, if the delay time is lower than the preset delay value, responding the audio playing request through the audio software soft decoding channel;
s42, if there are one or more audio playing requests with a delay time lower than the preset delay value in the two or more audio playing requests, responding to all the audio playing requests through the audio software soft decoding channel.
In this embodiment, first, if the delay time is lower than the preset delay value, the audio software soft decoding channel responds to the audio playing request; then, if one or more audio playing requests with the delay time lower than the preset delay value exist in the two or more audio playing requests, responding to all the audio playing requests through the audio software soft decoding channel.
Specifically, for a mobile phone as an example, the ADSP scheme of the mobile phone is that an audio module directly sends data to the ADSP module, and then transmits the processed data to a bluetooth connection module, thereby implementing a song listening function of the bluetooth headset, while the soft coding scheme is that the audio module sends data to a bluetooth protocol stack, and then codes the data through the bluetooth protocol stack, and transmits the processed data to the bluetooth connection module, thereby implementing the song listening function of the bluetooth headset. In this embodiment, an audio output management module and a bluetooth connection management module are added to implement a scheme of switching between soft coding and ADSP, the audio output management module is used to manage the transmission direction of data output by the audio module in two different schemes, and the bluetooth connection management module is used to manage currently connected bluetooth earphones, and simulate the currently connected bluetooth earphones into two different devices as output devices corresponding to the soft coding and ADSP schemes.
Specifically, for example, when a user connects to a bluetooth headset, the bluetooth connection management module simulates a new device for an output device of the soft coding scheme, and is in a connected but inactive state, so that in a non-game scene, the bluetooth module is an output device connected to and activated by the ADSP module; when a user starts playing audio, the system firstly judges whether the user is in a game scene; if not, maintaining the original output channel and equipment; if yes, the audio management module switches to switch audio output to a Bluetooth protocol stack, and meanwhile, the Bluetooth connection management module switches output equipment for the soft coding scheme to a connected and activated state for receiving Bluetooth audio data transmitted by the soft coding scheme. The method has the advantages that the user experience and better power consumption experience can be kept in the non-game scene, meanwhile, the scheme of low time delay is switched to the game scene sensitive to the sound delay of the user, so that the user experience is improved, meanwhile, the scheme can be applied to all third-party earphones, the earphones are not required to be adapted and modified, and the sound delay experience is improved.
The method has the advantages that the audio playing request is responded through the audio software soft decoding channel by judging whether the delay time is lower than the preset delay value; then, if one or more audio playing requests with the delay time lower than the preset delay value exist in the two or more audio playing requests, responding to all the audio playing requests through the audio software soft decoding channel. The more humanized Bluetooth audio control scheme is realized, the problems of power consumption and time delay balance in the Bluetooth audio transmission process are solved, and the playing experience of the Bluetooth audio is enhanced.

Based on the foregoing embodiments, the present invention further provides a bluetooth audio control device, including a memory, a processor, and a computer program stored on the memory and executable on the processor, where the computer program when executed by the processor implements:
when the terminal equipment detects that the Bluetooth equipment is connected, monitoring an audio playing request;
if the audio playing request is received, determining a generating scene of the audio playing request;
acquiring a time delay requirement of the audio playing according to the generated scene, and judging whether the time delay requirement is lower than a preset time delay value;
if the delay requirement is lower than the preset delay value, soft coding processing is carried out on the audio to be sent through a Bluetooth protocol stack and the audio is sent, and if the delay requirement is higher than the preset delay value, hard coding processing is carried out through a processor and the audio is sent.

In this embodiment, it should be noted that, considering the low latency requirement of the user in the bluetooth transmission process, the mobile phone is connected to the bluetooth headset to implement the low latency sound effect, and the bluetooth packet sending interval parameter and the packet sending size need to be adjusted to implement the low latency of the sound. The current mobile phone mostly adopts the scheme of ADSP (advanced digital signal processing), and because ADSP belongs to a hard coding scheme, parameter setting is difficult, so that the prior art cannot conveniently adjust the Bluetooth packet transmission interval parameter and the packet transmission size. The soft coding is to directly deliver the audio data to the bluetooth protocol stack, the audio data is coded by the bluetooth protocol stack, and then the audio data is transmitted by the bluetooth without being processed by the chip of the ADSP, so that all parameters such as packet transmission intervals, packet transmission sizes, coding modes and the like can be subjected to parameter adjustment by the bluetooth protocol stack, but the problem caused by the soft coding is high power consumption. Therefore, in this embodiment, the two usage scenarios are fused, and the current bluetooth audio transmission mode is adaptively determined, so that power consumption and resource consumption of bluetooth audio transmission are reduced under the condition of low delay requirement, and delay of bluetooth audio transmission is reduced under the condition of high delay requirement, so that user experience is enhanced.
Specifically, in this embodiment, when the terminal device detects that the bluetooth device is connected, an audio playing request is monitored, where the bluetooth device includes multiple types, one is a closed bluetooth device such as a bluetooth headset, the other is an open bluetooth device such as a bluetooth speaker, the third is a bluetooth switching device, and the audio playing request also includes requests from multiple sources, one is a playing request sent by different application programs, and the other is a playing request generated by different functions; then, if the audio playing request is received, determining a generation scene of the audio playing request, that is, adaptively determining a delay requirement of subsequent bluetooth audio playing according to specific scene information, wherein the scene information includes the type of the bluetooth device, playing requests of different application programs or functions, and the like; then, acquiring the time delay requirement of the audio playing according to the generated scene, and judging whether the time delay requirement is lower than a preset time delay value, namely, pre-judging or pre-estimating the current time delay requirement according to actual scene information to obtain a pre-judged or pre-estimated time delay value, and then comparing the time delay value with the preset time delay value under each scene; finally, if the delay requirement is lower than the preset delay value, soft coding processing is performed on the audio to be transmitted through a bluetooth protocol stack and the audio is transmitted, and if the delay requirement is higher than the preset delay value, hard coding processing is performed through a processor and the audio is transmitted.
The method has the advantages that the audio playing request is monitored when the terminal device detects that the Bluetooth device is connected; then, if the audio playing request is received, determining a generating scene of the audio playing request; then, acquiring a time delay requirement of the audio playing according to the generated scene, and judging whether the time delay requirement is lower than a preset time delay value; and finally, if the delay requirement is lower than the preset delay value, performing soft coding processing on the audio to be transmitted through a Bluetooth protocol stack and transmitting the audio, and if the delay requirement is higher than the preset delay value, performing hard coding processing through a processor and transmitting the audio. The humanized Bluetooth audio control scheme is realized, the problems of power consumption and time delay balance in the Bluetooth audio transmission process are solved, and the playing experience of the Bluetooth audio is enhanced.
