Detailed Description
To make the objects, technical solutions and advantages of the present disclosure more apparent, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.
The embodiment of the disclosure provides a method for playing audio data, which can be implemented by a terminal connected with at least two audio devices. The terminal can be a terminal with an audio playing function, such as a notebook computer, a tablet computer or a mobile phone, and can be provided with a music playing application program; the audio equipment can be an earphone and a speaker of the terminal, and can also be an external speaker, such as a Bluetooth sound box and the like, and is used for playing audio data; there are also various connection modes between the terminal and at least two audio devices, for example, the connection may be through a data line, a bluetooth connection, a wireless connection, or the like.
The terminal may include a processor, memory, etc. The processor, which may be a CPU (Central processing unit), may be configured to determine, according to a correspondence between pre-stored audio playing information and audio devices, a first audio device corresponding to current audio playing information in the at least two audio devices, and perform other processing. The Memory may be a RAM (Random Access Memory), a Flash Memory, and the like, and may be configured to store received data, data required by the processing procedure, data generated in the processing procedure, and the like, such as audio data, audio playing information, and the like. The terminal may also include a transceiver, input components, display components, audio input components, and the like. The transceiver may be used for data transmission with a server, for example, may obtain audio data from the server, and may include an antenna, a matching circuit, a modem, and the like. The input means may be a touch screen, keyboard, mouse, etc. The audio input means may be a microphone or the like.
As shown in fig. 1, the processing flow of the method may include the following steps:
in step 101, the terminal obtains current audio playing information.
The audio playing information may include one or more of audio playing volume, ambient noise volume, echo attribute information, and preset relative position information of the target device and each audio device. The preset target device is a portable device that can be carried by the user, and is used to detect the relative position between the user and each audio device, for example, the preset target device may be the terminal, such as a mobile phone that the user carries with, or a bracelet that is worn on the user.
In a possible implementation process, when a user wants to listen to a song, the music playing application program can be started on the terminal, the song that the user wants to listen to (which can be recorded as a target song) is selected from a song list provided by the music playing application program, and the playing key is clicked, so that the terminal can select the audio device used last time to play the target song, or the audio device can be determined to play the target song according to a pre-configured priority order of the audio device. When the user clicks the play key, the terminal is also triggered to acquire current audio play information, for example, the current audio play volume can be detected, environmental noise volume and echo attribute information can be acquired through an audio input component (such as a microphone), and relative position information of the target device and each audio device can also be acquired.
In step 102, the terminal determines, according to a correspondence between pre-stored audio playing information and audio devices, a first audio device corresponding to the current audio playing information among the at least two audio devices.
In a possible implementation process, a storage of the terminal may be pre-stored with a corresponding relationship between the audio playing information and the audio device, for example, when echo attribute information exists and the echo attribute information is greater than a preset threshold, the corresponding audio device is an audio device with an echo cancellation function, such as an earphone. For another example, the corresponding relationship between the audio playing volume and the audio device, such as the audio playing volume being smaller than the first volume threshold corresponding to the earphone, the audio playing volume being larger than the first volume threshold and smaller than the second volume threshold corresponding to the own speaker, the audio playing volume being larger than the second volume threshold corresponding to the external speaker, wherein, for determining the external speaker, the terminal may select an appropriate external speaker from the external speakers according to the audio playing volume. Therefore, the terminal can determine the first audio device corresponding to the current audio playing information in at least two audio devices in a connection state with the terminal according to the corresponding relationship between the pre-stored audio playing information and the audio devices, for example, when the terminal detects that the current audio playing volume exceeds the second volume threshold, the terminal can determine the external speaker corresponding to the current audio playing volume in the self-contained speaker and the external speaker in the connection state with the terminal according to the corresponding relationship between the audio playing volume and the audio devices.
In step 103, the terminal plays the audio data through the first audio device.
After the terminal determines the first audio device, it may first detect the audio device in the current use state, if the currently used audio device is the first audio device, continue to play the audio data through the first audio device, and if the currently used audio device is not the first audio device, switch the currently used audio device to the first audio device, and play the audio data through the first audio device.
For example, after the user selects the target song and clicks the play button, the terminal may play the target song according to the audio device that was most recently used (e.g., with its own speaker), or according to the audio devices determined by the pre-configured priority order. In the process of playing the target song, the terminal may periodically acquire current audio playing information, for example, when the terminal detects that the current audio playing volume exceeds a second volume threshold, the external speaker corresponding to the current audio playing volume may be determined in the self-contained speaker and the external speaker connected to the terminal according to a corresponding relationship between the audio playing volume and the audio device. And then, the terminal switches the self-contained loudspeaker into an external loudspeaker and plays the target song through the external loudspeaker.
Based on the above, in the process of playing the audio data, the terminal can not only play the audio data according to the audio device determined by the preset priority order, but also select the audio device corresponding to the current audio playing information to play the audio data according to the corresponding relationship between the audio playing information and the audio device, so that the flexibility of the terminal in selecting the audio device to play the audio data can be improved.
In addition, the terminal determines the audio equipment based on the audio playing information, so that the determined audio equipment is matched with the audio playing information, the effect of the audio equipment is better exerted, the effect of playing audio data by the terminal can be further improved, and the auditory effect of a user is improved. For example, for an audio device with an echo cancellation function, playing audio data in an environment where echoes are easily generated can better exert the effect, so that when the terminal detects echo attribute information, the audio device corresponding to the echo attribute information can be selected to play the audio data, and the effect of playing the audio data by the terminal is further improved. For example, for an external speaker (such as an external speaker) with a shocking sound effect, the effect of playing the audio data is better under the condition that the audio playing volume is larger, so that when the terminal detects that the audio playing volume is larger, the audio device corresponding to the audio playing volume can be selected to play the audio data, and further, the effect of playing the audio data by the terminal is improved.
Optionally, the terminal determines the audio device according to the audio playing information, and the terminal may further select the audio device to be used according to the audio playing information and the currently used audio device, and correspondingly, the terminal determines the currently used second audio device first, and then determines, in the at least two audio devices, the current audio playing information and the first audio device to be used corresponding to the currently used second audio device according to the pre-stored audio playing information, the correspondence between the currently used audio device and the audio device to be used.
In a possible implementation process, in the process of playing audio data, when it is detected that audio playing information changes, if the volume of ambient noise in the audio playing information is greater than a preset threshold, a second audio device currently used is further detected, and then the current audio playing information and a first audio device to be used corresponding to the second audio device currently used are determined according to pre-stored audio playing information and a corresponding relationship between the audio device currently used and the audio device to be used.
For example, when the terminal detects that the volume of the environmental noise in the audio playing information is greater than a preset threshold, it is further determined that the currently used audio device, such as a self-contained speaker, corresponds to the self-contained speaker according to that the volume of the environmental noise stored in advance is less than the preset threshold, and corresponds to an external speaker according to that the volume of the environmental noise is greater than the preset threshold, it is further determined that the audio device to be used is an external speaker, and then the self-contained speaker is switched to the external speaker by the terminal.
One possible application scenario may be that the user plays music using the self-contained speaker in an environment where the ambient noise volume is smaller than a preset threshold, and in the process of playing music, the environment becomes noisy suddenly, and accordingly, the terminal detects that the ambient noise volume is larger than the preset threshold, so that the terminal can switch the self-contained speaker to an external speaker, continue to play music for the user through the external speaker, and does not need to manually switch the audio device.
For another example, when the terminal detects that the volume of the environmental noise in the audio playing information is greater than the preset threshold, but further detects that the currently used audio device is an earphone, the terminal may not switch the audio device, that is, the terminal continues to play the audio data through the earphone.
One possible application scenario may be that the user uses the earphone to play music in an environment where the volume of the ambient noise is smaller than a preset threshold, and in the process of playing music, the environment becomes noisy suddenly, and accordingly, although the terminal detects that the volume of the ambient noise is larger than the preset threshold, since the currently used audio device is the earphone and the ability of the earphone to resist the ambient noise is strong, in order not to affect the music listening effect of the user, the audio device may not be switched, and the terminal continues to play music through the earphone.
The foregoing introduces a situation that the terminal determines the audio device based on the audio playing volume, the environmental noise volume, and the echo attribute information, and certainly, the terminal may also determine the audio device according to the comprehensive information of the audio playing volume, the environmental noise volume, and the echo attribute information, for example, when the terminal detects that the environmental noise volume is greater than a preset threshold, the audio playing volume is further determined, if the audio playing volume is greater than a first volume threshold and less than a second volume threshold, the terminal may select a speaker to play the audio data, and if the audio playing volume is greater than the second volume threshold, the terminal may select an external speaker to play the audio data. For another example, the terminal may further determine the audio device according to the audio playing volume, the ambient noise volume, and the component occupied by the echo attribute information, for example, if the audio playing volume is greater than the maximum component occupied by the second volume threshold, the terminal may select an external speaker to play the audio data, the echo attribute information exists in the environment where the terminal is located, and the echo is still relatively large, that is, the component occupied by the echo attribute information is relatively large, and the terminal may select an audio device with echo cancellation, such as an earphone, to play the audio data.
In the above description, the terminal determines the audio devices based on the audio playing volume, the ambient noise volume, and the echo attribute information, and may also determine the audio devices according to the preset corresponding relationship between the target device and each audio device and the audio devices, where correspondingly, the terminal may first determine the relative positions between the target device and each audio device, and then determine the audio device closest to the target device, and play the audio data through the audio device.
It can be known from the foregoing that the target device may be an execution main body terminal of this embodiment, such as a mobile phone, or a portable device carried by a user, such as a bracelet, a wristwatch, and the like, and the target device is used for reflecting relative position information between the user and each audio device. In the following, the target device is taken as an example of a portable device carried by a user, and the situation that the target device is a terminal is similar to the target device, and thus, the description is omitted.
In one possible implementation, the relative location information of the target device and each audio device may be the coordinate location of the target device in a coordinate system established with each audio device as a coordinate origin. For example, a plurality of audio devices (e.g., sound boxes) are placed in a room where a user is located, as shown in fig. 2, four audio devices, denoted as A, B, C and D, are placed in the room, and all of the four audio devices are in a connected state with the terminal, and four coordinate systems are established with A, B, C and D as coordinate origins, respectively, so that the coordinate positions of the target device in the four coordinate systems, respectively, are the relative position information of the target device and each audio device.
As shown in fig. 2, a region a is a better auditory effect for playing audio data using the a audio device, a region B is a better auditory effect for playing audio data using the B audio device, a region C is a better auditory effect for playing audio data using the C audio device, and a region D is a better auditory effect for playing audio data using the D audio device. Then, when the terminal detects that the target device is in the area a, the audio device corresponding to the audio device a may be selected to play the audio data, and when the terminal detects that the target device moves to the area B, the audio device corresponding to the audio device a may be switched to the audio device corresponding to the audio device B.
One possible application scenario may be that the user places an audio device in each room, for example, places an audio device in each of rooms E, F, and G, and the audio devices are connected to a terminal for controlling the audio devices to play audio data. The terminal can be a computer and can be placed in any room, the target device can be a portable device worn on a user, therefore, when the user is in the E room, the audio device in the E room plays audio data, the audio devices in other rooms do not need to play, when the user is transferred from the E room to the F room, at the moment, the terminal switches the audio device in the E room into the audio device in the F room, and the audio device in the F room plays audio data. Therefore, the user can hear the audio data when walking to any room, the flexibility of listening to the music of the user is improved, and the situation that the user cannot hear the music when changing to another room is avoided.
Optionally, the terminal may determine the audio device according to one or more of the audio playing volume, the ambient noise volume, the echo attribute information, and the preset relative position information between the target device and each audio device, and may switch the audio device in use according to the playing noise volume of the audio device, correspondingly, the terminal may acquire the playing noise volume of the currently used audio device in the process of playing the audio data, and if the playing noise volume is greater than the preset threshold, determine a fourth audio device other than the currently used audio device in the at least two audio devices, and play the audio data through the fourth audio device.
The volume of the playing noise of the audio device is the volume of the playing noise related to the audio device, for example, the playing noise generated when the audio device is faulty, for example, the playing noise generated when data loss occurs in the transmission process from the terminal to the audio device of the audio data, for example, the playing noise generated when the audio data is interfered by other signals in the transmission process, for example, the playing noise generated when a microphone is too close to the audio device in use also generates howling, and the like.
In a possible implementation process, in the process of playing the audio data, the terminal may detect the playing noise through the microphone, and when it is detected that the volume of the playing noise is greater than a preset threshold, determine, among the at least two audio devices, a fourth audio device other than the currently used audio device, and play the audio data through the fourth audio device. That is to say, when the terminal detects that the audio device in use is playing audio data, the terminal sends out playing noise, and the volume of the playing noise is greater than the preset threshold, the audio device in use is switched. And if the switched audio equipment also emits playing noise, and the volume of the playing noise is greater than the preset threshold value, switching the audio equipment again until the volume of the playing noise emitted by the audio equipment is less than the preset threshold value. Therefore, when the audio equipment in use breaks down and the volume of playing noise is larger than the preset threshold value, the terminal can automatically switch the audio equipment without manually switching the audio equipment by a user, and compared with the related art, the user experience can be improved.
Optionally, when the terminal switches the audio device being used, the terminal may perform a delayed switching for a less abrupt switching, and correspondingly, if the terminal currently plays the audio data through the second audio device, the terminal plays the audio data through the first audio device when a preset time is reached after determining the target audio device corresponding to the current audio playing information.
In a possible implementation process, if the terminal is playing audio data using the second audio device, when it is detected that the audio playing information changes and the audio device corresponding to the changed audio playing information is the first audio device, the terminal determines that the time length of the first audio device reaches a preset time length, for example, when it is determined that the time length of the first audio device reaches 1 second, the second audio device is switched to the first audio device, and the audio data is played through the first audio device. Therefore, the user experience can be improved by switching the audio equipment in a delayed manner, and the discomfort of hearing of the user caused by suddenly switching the audio equipment is avoided.
Optionally, after the terminal determines the first audio device and before the audio device being used is switched, a switching prompt may be sent to the user, and correspondingly, if the terminal currently plays audio data through the second audio device, a prompt window for switching to the first audio device is displayed; and when the terminal receives a switching confirmation instruction triggered by the prompt window, the terminal plays the audio data through the first audio equipment.
In one possible implementation, after the terminal determines the first audio device to be used and the second audio device being used, as shown in fig. 3, a prompt window for switching to the first audio device may be displayed through a display screen of the terminal. After the user sees the prompt window, if the user intends to switch, the user can click to determine, the terminal can receive a switching confirmation instruction triggered by the prompt window, then the terminal switches the second audio device to the first audio device, and the audio data is played through the first audio device. And if the user does not intend to switch and can click to cancel, the terminal can receive a switching canceling instruction triggered by the prompt window, and then the terminal continues to play the audio data through the second audio equipment. In another case, if the user does not notice the prompt window displayed on the display screen of the terminal, and correspondingly, the terminal does not receive the switching confirmation instruction or the switching cancellation instruction triggered by the prompt window within the preset time period, the terminal may automatically switch the second audio device to the first audio device from the viewpoint of improving the audio data playing effect, and play the audio data through the first audio device.
Optionally, the terminal determines an audio device according to a change of the audio playing information, of course, the user may also select an audio device according to his/her own will, and after the audio device is determined by the terminal based on the selection instruction of the user, the terminal may no longer switch the audio device according to the audio playing information.
