Description
Technical Field
The invention relates to the technical field of Bluetooth communication, in particular to a method and a terminal for playing audio through Bluetooth equipment.
Background
At present, the same terminal may establish a communication connection with two bluetooth devices, and after the communication connection is successfully established, the terminal also establishes a connection with A2DP (Advanced Audio Distribution Profile) and HFP (Hands-free Profile) data channels of each bluetooth device. The A2DP data channel is used for playing media audio of the terminal, and the HFP data channel is used for playing terminal call audio. But only one channel of one bluetooth device is in an active state, and the other channels are in a dormant state, namely, only one bluetooth device can play media audio or call audio.
In the prior art, when audio needs to be played through a bluetooth device, a terminal determines the bluetooth device used for playing the type of audio for the last time, and still adopts the bluetooth device used for the last time during the playing; for example, when media audio playing is started, if it is determined that the bluetooth device used when the media audio is played last time is the bluetooth device1, the terminal uses the bluetooth device1 to play the media audio; for another example, when the call audio is started, if it is determined that the bluetooth device used when the audio was played last time is the bluetooth device2, the terminal uses the bluetooth device2 to play the call audio. However, for the user, when the media audio or the call audio is played through the bluetooth device, only the bluetooth device which is used for playing the same type of audio at the last time can be adopted, so that it is difficult to ensure that the bluetooth device which is to be used for playing the media audio or the call audio at this time meets the user requirement; for example, the terminal establishes a connection with the bluetooth headset and the vehicle-mounted device at the same time, and when the terminal starts a call service, the user wants to play the call audio through the bluetooth headset, but since the bluetooth device used for playing the call service is played last time, the situation that the call audio is played through the vehicle-mounted device occurs.
To sum up, the current scheme for playing the terminal audio through the bluetooth device cannot reasonably select the bluetooth device to be used for playing the media audio or the call audio according to the requirement of the user, and the current scheme for playing the terminal audio through the bluetooth device is not flexible.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Bluetooth wireless communication technology has started from version 4.0 and includes two standards, namely, Bluetooth dual-mode standard, which includes two parts, namely, conventional Bluetooth (or Classic Bluetooth) and Bluetooth Low Energy (Bluetooth Low Energy). For example, a classic bluetooth device may be a bluetooth headset, a speaker, an in-vehicle device, etc.; the low-power consumption bluetooth equipment can be for intelligent wearing equipment, intelligent bracelet, mouse, keyboard etc.. Since the dual mode standard is supported, the terminal can theoretically connect a plurality of different bluetooth devices at the same time.
When the terminal is connected with the bluetooth device, besides a transmission link of information data stream is realized through a bluetooth bottom layer protocol, functions such as decomposition and recombination of data frames, quality of service control, group extraction and the like are completed through a bluetooth intermediate protocol, for each specific application scene and different protocol stacks of each application, Profile (configuration file) corresponding to a bluetooth high layer protocol is needed to realize combination of bottom-up protocols corresponding to a certain function, each Profile corresponds to different application functions, wherein the bluetooth device supporting audio playing comprises support HFP and A2DP which are respectively used for processing application scenes related to conversation audio and media audio. The bluetooth protocol framework is shown in fig. 1 and includes a bottom layer protocol, a middle layer protocol and an application high layer protocol; wherein the bottom layer protocol comprises a Link Management Protocol (LMP), a baseband (Base Band) and a Radio Frequency (RF); the intermediate protocol layer comprises a logical link control and adaptation protocol (L2CAP), a serial port simulation protocol (RFCOMM) and a Service Discovery Protocol (SDP); the application high-level protocols include A2DP, HFP, HSP, OPP, PBAP, PAN, HID, SPP, etc. (of which only A2DP and HFP are taken as examples in fig. 1), A2DP is used to process media audio according to AT commands, and HFP is used to process call audio according to AT commands.
After the terminal establishes a connection with two bluetooth devices supporting call audio and media audio simultaneously, an audio channel as shown in fig. 2 is established. Suppose that the terminal establishes a first media audio channel and a first call audio channel with the bluetooth device1, and the terminal establishes a second media audio channel and a second call audio channel with the bluetooth device 2. And the terminal controls the first media audio channel of the Bluetooth device1 and the second media audio channel of the Bluetooth device2 through the internal media audio channel control module, and controls the first call audio channel of the Bluetooth device1 and the second call audio channel of the Bluetooth device2 through the internal call audio control module. The media audio channel and the call audio channel are two mutually independent channels, and only one channel is in an activated state at the same time. In the audio playing mode in the prior art, when a terminal starts media audio or call audio playing, the terminal selects an audio channel to be used through respective corresponding audio channel control modules. For example, when the terminal starts a call audio, the call audio control module determines the bluetooth device used by playing last time, and if the bluetooth device1 is assumed, the call audio control module activates a first call audio channel of the bluetooth device1 and plays the call audio through the first call audio channel.
In the prior art, a terminal establishes a media audio channel and a call audio channel for each Bluetooth device, a call audio control module is used for selecting the call audio channel, and the media audio control module is used for selecting the media audio channel and adopts the audio channel used by playing audio at the last time; however, before playing the audio, the user cannot know from which bluetooth device the audio to be played will be played, and cannot reasonably select the bluetooth device to be used for playing the media audio or the call audio according to the user's requirement.
An embodiment of the present invention provides a method for playing audio through a bluetooth device, as shown in fig. 3, the method includes:
The at least two Bluetooth devices connected with the terminal are Bluetooth devices supporting media audio playing and/or conversation audio playing; the audio to be played is media audio or call audio.
After the terminal establishes connection with at least two Bluetooth devices supporting audio playing, the terminal can determine a target Bluetooth device selected by a user from the Bluetooth devices connected with the terminal according to an operation instruction of the user; the terminal switches the audio channel to be played to the target Bluetooth equipment through the Bluetooth control interface, and the target Bluetooth equipment plays the audio to be played; according to the embodiment of the invention, the user sets the target Bluetooth equipment according to the self requirement, the terminal determines the target Bluetooth equipment set by the user, and the audio is played through the target Bluetooth equipment set by the user, so that the scheme for playing the terminal audio through the Bluetooth equipment provided by the embodiment of the invention can reasonably select the Bluetooth equipment for playing the audio according to the requirement of the user, and the flexibility of the method for playing the audio through the Bluetooth equipment is improved.
An optional way to implement the above playing audio through the bluetooth device is to add a channel switching preprocessing module in the terminal, where the channel switching preprocessing module maintains a bluetooth device list connected to the terminal and a target bluetooth device selected by a user. Before the terminal plays audio, the channel switching preprocessing module determines an audio channel required to be used according to the target Bluetooth device set by the user and informs the corresponding audio channel control module.
In the embodiment of the invention, after the terminal establishes connection with two Bluetooth devices which simultaneously support conversation audio and media audio, an audio channel as shown in figure 4 is established. Suppose that the terminal establishes a first media audio channel and a first call audio channel with the bluetooth device1, and the terminal establishes a second media audio channel and a second call audio channel with the bluetooth device 2. A channel switching preprocessing module, a media audio channel control module and a call audio control module are arranged in the terminal; the terminal determines that a target Bluetooth device set by a user is a Bluetooth device1 through a channel switching preprocessing module, and when the audio to be played is a call audio, the channel switching preprocessing module informs a call audio control module to activate a first call audio channel of the Bluetooth device1 and uses the first call audio channel to play the call audio; when the audio to be played by the terminal is the media audio, the channel switching preprocessing module informs the media audio control module to activate the first media audio channel of the bluetooth device1, and the first media audio channel is used to play the media audio.
In implementation, the bluetooth control interface mainly implements switching logic for controlling the output device of the audio channel; wherein, the output device of the audio channel comprises all connected Bluetooth audio devices, hands-free devices, earphones, wired earphones and the like.
After the terminal starts the bluetooth, any method in the prior art may be used to establish a connection with at least two bluetooth devices that support playing media audio and/or call audio, which is not limited herein.
After the terminal establishes connection with the Bluetooth equipment, a Bluetooth selection interface is presented to a user; the Bluetooth selection interface comprises a list of at least two Bluetooth devices connected with the terminal.
After the terminal presents the Bluetooth selection interface to the user, the user selects a target Bluetooth device for playing audio through the Bluetooth selection interface.
In implementation, a user can select one bluetooth device from a bluetooth device list contained in a bluetooth selection interface as a target bluetooth device; or the user selects two Bluetooth devices from a Bluetooth device list contained in the Bluetooth selection interface, and the two Bluetooth devices are respectively used as a first target Bluetooth device for playing the call audio and a second target Bluetooth device for playing the media audio.
The following is a detailed description of different numbers of target bluetooth devices.
Firstly, selecting a target Bluetooth device.
For example, after the terminal starts the bluetooth, the terminal establishes connection with two bluetooth devices supporting audio playing, and the two bluetooth devices are respectively a bluetooth device1 and a bluetooth device 2; as shown in fig. 5, a bluetooth selection interface of the terminal includes a list of bluetooth devices 1 and 2;
in addition, the Bluetooth selection interface also comprises a default option which indicates that the user does not select the target Bluetooth equipment when the user selects the default option;
it should be noted that, when the user does not select the target bluetooth device, and the audio to be played is the call audio, the terminal switches the call audio channel to be played to the bluetooth device used when the call audio is played last time through the bluetooth control interface, and the bluetooth device used when the call audio is played last time plays the call audio to be played; when the audio to be played is the media audio, the terminal switches the media audio channel to be played to the Bluetooth device used for playing the media audio last time through the Bluetooth control interface, and the Bluetooth device used for playing the media audio last time plays the media audio to be played; the Bluetooth device used for playing the media audio last time can be the same as or different from the Bluetooth device used for playing the call audio last time.
After the user selects the bluetooth device1, the terminal has a bluetooth selection interface as shown in fig. 6 according to the operation instruction of the user. Indicating that the user sets the bluetooth device1 as a target bluetooth device.
It should be noted that the foregoing description of the bluetooth selection interface in the embodiment of the present invention is only exemplary, and other manners of presenting the bluetooth selection interface are also applicable to the present invention.
An optional implementation manner is that, in the embodiment of the present invention, the terminal defines a static variable, targetglobothdevice, for recording information of a target bluetooth device selected by a user; after a user selects a target Bluetooth device in a Bluetooth selection interface through an operation command, the terminal sets the value of a static variable targetBluetooth device as identification information of the target Bluetooth device selected by the user; for example, when the user selects the bluetooth device1 as the target bluetooth device through the operation instruction, the value of the targetbluetooth device is set as the identification information of the bluetooth device 1; or, when the user selects the bluetooth device2 as the target bluetooth device through the operation instruction, the value of the targetbluetooth device is set as the identification information of the bluetooth device 2.
In addition, when the user selects the "default" option in the bluetooth selection interface, which indicates that the user has not selected the target bluetooth device, the value of the static variable targetglobothdevice is set to "null" at this time.
After a target Bluetooth device is set in the mode, before audio is played, the terminal obtains the value of a static variable targetBlueToothdevice, and the target Bluetooth device selected by a user is determined according to the value of the static variable targetBlueToothdevice;
for example, if the value of the static variable targetblockothdevice is the identification information of the bluetooth device1, the terminal switches the audio channel to be played to the bluetooth device1, and the bluetooth device1 plays the audio to be played; and if the value of the static variable targetBlueTothdevice is the information of the Bluetooth device2, the terminal switches the audio channel to be played to the Bluetooth device2, and the Bluetooth device2 plays the audio to be played.
It should be noted that, when only one target bluetooth device is set, and when the audio to be played is a call audio or a media audio, the terminal sends the audio to be played to the same target bluetooth device selected by the user.
The method for playing audio via a bluetooth device when selecting a target device will be described in detail below with reference to fig. 7.
Suppose that the terminal establishes a connection with two bluetooth devices after bluetooth is turned on, and both bluetooth devices support call audio and media audio.
As shown in fig. 7, a flowchart of playing audio through a bluetooth device according to an embodiment of the present invention:
And II, selecting two target Bluetooth devices.
The two target bluetooth devices selected by the user are respectively: the device comprises a first target Bluetooth device used for playing conversation audio and a second target Bluetooth device used for playing media audio.
For example, after the terminal starts the bluetooth, the terminal establishes connection with two bluetooth devices supporting audio playing, and the two bluetooth devices are respectively a bluetooth device1 and a bluetooth device 2;
the bluetooth selection interface of the terminal is shown in fig. 8, and the bluetooth selection interface of the terminal includes a selection area of a first target bluetooth device and a selection area of a second target bluetooth device; the selection area of the first target bluetooth device contains a bluetooth device list (bluetooth device1 and bluetooth device 2) connected with the terminal, and the selection area of the second target bluetooth device contains a bluetooth device list (bluetooth device1 and bluetooth device 2) connected with the terminal.
It should be noted that the first target bluetooth device and the second target bluetooth device in the embodiment of the present invention may be the same or different, that is, the user may select the same bluetooth device to play the media audio and the call audio, or select different bluetooth devices to play the media audio and the call audio, respectively.
In addition, the selection area of the first target Bluetooth device and the selection area of the second target Bluetooth device both comprise a default option;
specifically, if the user selects the default option in the selection area of the first target bluetooth device, it indicates that the user does not select the first target bluetooth device for playing the call audio; under the condition, when the audio to be played is the call audio, the terminal switches the call audio channel to be played to the Bluetooth device used for playing the call audio last time, and the Bluetooth device used for playing the call audio last time plays the call audio to be played;
if the user selects the default option in the selection area of the second target Bluetooth device, the user does not select the second target Bluetooth device for playing the media audio; under the condition, when the audio to be played is the media audio, the terminal switches the media audio channel to be played to the bluetooth device used for playing the media audio last time, and the bluetooth device used for playing the media audio last time plays the media audio to be played.
It is assumed that the first target bluetooth device and the second target bluetooth device selected by the terminal according to the operation instruction of the user are as shown in fig. 9; it means that the user sets the first target bluetooth device as bluetooth device1 and sets the second target bluetooth device as bluetooth device 2. When the audio to be played is a call audio, the terminal switches the call audio channel to be played to the bluetooth device1, and the bluetooth device1 plays the call audio channel; when the audio to be played is the media audio, the terminal switches the media audio channel to be played to the bluetooth device2, and the bluetooth device2 plays the audio.
It should be noted that the above description of the bluetooth selection interface in the embodiment of the present invention is only exemplary, and other presentation manners of the bluetooth selection interface are also applicable to the present invention.
An optional implementation manner is that, in the embodiment of the present invention, the terminal defines two static variables, which are respectively used to record information of the first target bluetooth device and information of the second target bluetooth device set by the user; for example, the two static variables are targetbiunterothdevice 1 and targetbiunterothdevice 2, respectively, where targetbiunterothdevice 1 is used to record identification information of a first target bluetooth device set by a user, and targetbiunterothdevice 2 is used to record identification information of a second target bluetooth device set by the user.
For a first target bluetooth device: after a user selects a first target Bluetooth device from a corresponding Bluetooth device list in a selection area of the first target Bluetooth device in a Bluetooth selection interface through an operation command, the terminal sets the value of a static variable targetBlueToothdevice1 as identification information of the first target Bluetooth device selected by the user; for example, when the user selects the bluetooth device1 as the first target bluetooth device through the operation instruction, the value of the targetglobothdevice 1 is set as the identification information of the bluetooth device 1; or when the user selects the bluetooth device2 as the first target bluetooth device through the operation instruction, setting the value of the targetbluetooth device1 as the identification information of the bluetooth device 2;
in addition, when the user selects the "default" option while selecting the first target bluetooth device, which means that the user does not select the first target bluetooth device, the value of the static variable targetglobothdevice 1 is set to "null" at this time.
For a second target bluetooth device: after a user selects a second target Bluetooth device from the corresponding Bluetooth device list in a selected area of the second target Bluetooth device in the Bluetooth selection interface through an operation command, the terminal sets the value of a static variable targetBluetooth device2 as the identification information of the second target Bluetooth device selected by the user; for example, when the user selects the bluetooth device1 as the second target bluetooth device through the operation instruction, the value of the targetglobothdevice 2 is set as the identification information of the bluetooth device 1; or when the user selects the bluetooth device2 as the second target bluetooth device through the operation instruction, setting the value of the targetbluetooth device2 as the identification information of the bluetooth device 2;
in addition, when the user selects the "default" option while selecting the second target bluetooth device, which means that the user does not select the second target bluetooth device, the value of the static variable targetglobothdevice 2 is set to "null" at this time.
After the first target Bluetooth device and the second target Bluetooth device are set in the manner, the terminal determines a first target Bluetooth device selected by the user from the list of the at least two Bluetooth devices and used for playing the call audio according to a first operation instruction of the user; and according to a second operation instruction of the user, determining a second target Bluetooth device selected by the user from the list of the at least two Bluetooth devices and used for playing the media audio.
Specifically, when the audio to be played is a call audio, the terminal obtains a value of a static variable targetblockothdevice 1, and determines a first target bluetooth device according to the value of the static variable targetblockothdevice 1; for example, if the value of the static variable targetblockothdevice 1 is the identification information of the bluetooth device1, the terminal determines that the first target bluetooth device for playing the call audio is the bluetooth device 1; or, if the value of the static variable targetbetalotythevice 1 is the identification information of the bluetooth device2, the terminal determines that the first target bluetooth device for playing the call audio is the bluetooth device 2.
When the audio to be played is media audio, the terminal obtains the value of a static variable targetBlueTothdevice 2, and determines a second target Bluetooth device according to the value of the static variable targetBlueTothdevice 2; for example, if the value of the static variable targetbetalotythevice 2 is the identification information of the bluetooth device1, the terminal determines that the second target bluetooth device for playing the media audio is the bluetooth device 1; or, if the value of the static variable targetbetalotythevice 2 is the identification information of the bluetooth device2, the terminal determines that the second target bluetooth device for playing the media audio is the bluetooth device 2.
