detailed description

In order to enable those skilled in the art to better understand the solution of the present application, the technical solution 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.

With the increase in the types of audio playback devices and the improvement of playback sound effects, more users will choose to output audio to be played by electronic devices such as mobile phones and tablets to the audio playback device for playback. Among them, common audio playback devices include car music players, speakers, and headphones.

According to different connection methods, audio playback devices can be divided into wired audio playback devices and wireless audio playback devices. The electronic device can interact with the wireless audio playback device through a wireless network to transmit signals. The wireless network may be Bluetooth. , Wifi, LTE network or NFC, etc.

Exemplarily, as shown in FIG. 1, a block diagram of a voice system provided by an embodiment of the present application is shown. Specifically, the voice system includes an electronic device 100, a first wireless audio playback device 210, and a second wireless audio playback device 220. The electronic device 100 can be connected to the first wireless audio playback device 210 and the second wireless audio playback device 220 at the same time.

In the embodiment of the present invention, an application capable of playing audio is installed in the electronic device 100. Specifically, the application may be audio playing software, video playing software, or calling software. The electronic device 100 sends the audio to be played to the first wireless audio playback device 210 or the second wireless audio playback device 220, and the first wireless audio playback device 210 or the second wireless audio playback device 220 plays the voice.

In the embodiment of the present invention, the first wireless audio playback device 210 and the second wireless audio playback device 220 may both be Bluetooth speakers or Bluetooth headsets. The first wireless audio playback device 210 and the second wireless audio playback device 220 may be enabled with the Bluetooth function. A connection with the electronic device 100 is achieved, and after the connection is established, the electronic device 100 sends the voice that it needs to play to the Bluetooth audio, and the Bluetooth audio implements voice playback.

When the first wireless audio playback device 210 and the second wireless audio playback device 220 are both Bluetooth devices, the electronic device 100 can be connected to the first wireless audio playback device 210 and the second wireless audio playback device 220 through the Bluetooth module at the same time. In an implementation manner, the Bluetooth module in the electronic device may support multipoint connection, so that the electronic device shown in FIG. 1 can be connected to the first wireless audio playback device 210 and the second wireless audio playback device 220, respectively. After the connection, the electronic device 100 can obtain the identities of the first wireless audio playback device 210 and the second wireless audio playback device 220, and the identifications may be MAC addresses. Specifically, when the Bluetooth function of the electronic device is turned on, the electronic device scans the Bluetooth devices within a certain distance from the surrounding area. Specifically, after receiving the scan command from the electronic device's Bluetooth chip or other underlying network module, the preset Scan in the order of channel scanning. For example, scan the common channels 1, 7, and 13 first, and then scan the other unused channels, so as to obtain the identification of all Bluetooth devices in the current range and display them in the Bluetooth list interface of the electronic device. .

If there is a connected Bluetooth device with a better signal strength in the scanned Bluetooth device identification, the electronic device will automatically connect with the Bluetooth device, and the user can also select a Bluetooth device in the Bluetooth list interface to connect.

When the electronic device is connected to an external Bluetooth device, the system of the electronic device obtains a status value, which indicates that the electronic device is currently connected to the Bluetooth device. Therefore, the electronic device can detect that the Bluetooth device is already present, and thereby obtain the device identification of the Bluetooth device.

As another implementation manner, as shown in FIG. 2, the electronic device 100 is connected to the first wireless audio playback device 210 through Bluetooth, and then the first wireless audio playback device 210 is connected to the second wireless audio playback device 220 through Bluetooth. Therefore, the electronic device 100, the first wireless audio playback device 210, and the second wireless audio playback device 220 are simultaneously connected through networking, that is, the first wireless audio playback device 210 serves as the electronic device 100 and the second wireless audio playback device 220. Repeater.

Therefore, after the electronic device 100 is connected to the first wireless audio playback device 210 and the second wireless audio playback device 220 at the same time, different audio playback devices can play different audio data. Of course, it can also be played by different audio playback devices. Same audio data to achieve effects like stereo. It is also possible to use one of the wireless audio playback devices to play audio data while the other wireless audio playback device is on standby without playing audio.

However, the inventor found in the research that when the user abandons using one of the wireless audio playback devices to listen to the audio data, because the audio data played by the two wireless audio playback devices cannot be heard at the same time, the effect of mixing playback cannot be obtained , Resulting in poor user experience.

Therefore, in order to solve the above technical defects, an embodiment of the present application provides an audio playback method, which is applied to the above electronic device. Specifically, the method includes: S301 to S304.

S301: When two of the wireless audio playback devices are playing different audio data to achieve mixed audio playback, determine whether each of the wireless audio playback devices is in a preset state.

Among them, the two wireless audio playback devices play different audio data, and the user can obtain the visual effect of mixing playback by listening to the audio data played by the two wireless audio playback devices at the same time. For example, in order to enable the user to realize the special effect of music replay when playing music, the audio data played by the two wireless audio playback devices can be made the same, for example, the two audio data are the same song, and the two audio data are The sampling frequency, the number of sampling bits, the bit rate, and the corresponding content are all the same.

Therefore, when a user plays a song, the same song is played on two wireless audio playback devices at different frequencies, and the frequency represents the tone of the sound, for example, one imitates the tone of a male voice and the other imitates the tone of a female voice, thereby Realize the effect of male and female duet.

For another example, the audio data played by two wireless audio playback devices can achieve the effect of stereo playback. Specifically, among the two wireless audio playback devices, one wireless audio playback device is playing the left channel data of the audio data. A wireless audio playback device is playing the right channel data of the audio data to achieve stereo playback of the audio data. Specifically, the audio data played by the two wireless audio playback devices are the same song and recorded as the target song. The target song can be divided into left and right channel data, that is, left channel data and right channel data. Both the channel data and the right channel data correspond to the target song, then one of the wireless audio playback devices plays the left channel data of the target song, and the other wireless audio playback device plays the right channel data of the target song, and the user listens to the target at the same time Audio data of the left and right channels of the song to achieve a stereo effect.

As an implementation manner, in order to better implement the duet and stereo effects described above, the wireless audio playback device may be a wireless headset, specifically, a Bluetooth headset.

As another implementation manner, the wireless audio playback device may also be a wireless speaker, for example, a Bluetooth speaker. The effect of simultaneous translation can be achieved through the wireless speaker. Specifically,

After acquiring the first audio data, the electronic device generates second audio data according to the first audio data, wherein a language corresponding to the first audio data is different from a language corresponding to the second audio data. The first audio data and the second audio data may correspond to different languages, or may correspond to the same language and different languages. For example, if the language corresponding to the first audio data is Chinese and the language corresponding to the second audio data is English, the first audio data and the second audio data correspond to different languages. For another example, the language corresponding to the first audio data is Cantonese , And the language corresponding to the second audio data is Mandarin, the first audio data and the second audio data correspond to the same language, but the corresponding languages are different

Specifically, translation software is installed in the electronic device, and after acquiring the first audio data, the translation software is called to generate the first audio data into the second audio data. Then, the first audio data and the second audio data may be obtained in advance, for example, downloading the first audio data and the second audio data on a website. For example, if the content of the first audio data is "I am Chinese and I love my motherland", then the content of the second audio data is "I am Chinese, I love my country." When "I am Chinese", the second audio data starts playing, and when "I love my motherland" is played by the first audio data, the second audio data is also playing.

It should be noted that, when two users are in a voice chat, the first audio data is acquired in real time and continuously, and the second audio data is also acquired continuously in real time. The time difference between the starting point of the second playback time can be set according to experience. As an implementation, the time for a user to speak a sentence or a paragraph is a preset time. The preset time can be statistically obtained according to the habits of the user, and the time difference N times the preset time, where N is a value greater than 0 and less than 1.

An implementation manner of determining that the two wireless audio playback devices are playing different audio data to implement mixed audio playback may be that the electronic device is connected to the first wireless audio playback device and the second wireless audio playback device at the same time, and the user is playing the When audio data is selected, the music to be played can be selected on the audio playback interface of the electronic device, as shown in the display interface of the electronic device shown in FIG. 1 and FIG. 2. Select one or more of the audio data and click the play button to play it. The selected audio data. In addition, the user can also select a wireless audio playback device for playing audio data through the electronic device.

For example, as shown in FIG. 4, a device management interface of an electronic device is shown. In the device management interface, an operation interface of two wireless audio playback devices connected to the electronic device is displayed, and specifically includes two wireless audio playback devices. A device selection button, which is a selection button corresponding to each device in FIG. 4, for example, when the round button is on the left, the electronic device selects a wireless audio playback device to play audio data. After the connection is established, the audio data played by the electronic device can play the audio data through the connected wireless audio playback device.

In addition, in this interface, each wireless audio playback device also corresponds to a drop-down menu. The user can configure the user's audio playback application for the wireless audio playback device through the drop-down menu. For example, configure the first audio data for device 1 as The device 2 is configured with the second audio data. If the electronic device can control the playback of the first audio data and control the playback of the second audio data, the device 1 can play the first audio data and the device 2 can play the second audio data. To achieve the effect of mixed playback.

Therefore, whether the electronic device is connected to the first wireless audio playback device can be determined through the button status in the interface. In addition, whether the device connected by the electronic device through Bluetooth is an audio playback device can be detected. In an electronic device, the type of the device currently connected via Bluetooth can be determined based on the return value obtained by instantiating the BluetoothClass.Device class. If the returned value is AUDIO_VIDEO_CAMCORDER, it is characterized as an image capture device; if the returned value is AUDIO_VIDEO_CAR_AUDIO, it is characterized as a car device; if the returned value is AUDIO_VIDEO_HIFI_AUDIO, it is characterized as an audio playback device or a video playback device, such as a Bluetooth headset; If the returned value is AUDIO_VIDEO_MICROPHONE, it indicates that it is a microphone.

When it is determined that the electronic device is connected to the wireless audio playback device, that is, after the electronic device is connected to the wireless audio playback device, it is detected whether the electronic device has received a playback request, and the playback request is a request for playing audio data. When the electronic device is connected to the first wireless audio playback device and the first wireless audio playback device is selected as a device for playing audio data of the electronic device, it is determined whether a playback request for audio data of the data is obtained when the user operates the electronic device, and if Upon the playback request, it is determined that the electronic device is playing audio data through the first wireless audio playback device.

Specifically, the playback request may be reminder information or a voice playback request. The reminder information includes call reminder information, short message reminder information, and alarm reminder information to remind the user that certain events have been triggered. For example, the call reminder information is used to remind the user of an incoming call.

As another implementation manner, the playback request may be a request to play a voice each time during the sounding process of the electronic device. The playback request may be an audio sound request, or a video sound request or a call sound request.

Specifically, if multiple audio playback software is installed in the electronic device, the software may be a music playback APP, a video playback APP, a recording APP, or the like. For example, the video playback interface is provided with a video playback button. By detecting the touch of the video playback button, it can be determined whether the electronic device currently receives a playback request for audio data. For example, the user selects a video, enters the video playback interface, and clicks. The playback button of the playback interface allows the application to detect what type of video the user is currently clicking by monitoring the user ’s touch operation. Specifically, the playback button is set with preset attributes to detect the acquired touch By operating the properties of the corresponding playback button, the user can determine the video to be played selected by the user, and then obtain a playback request and the audio corresponding to the playback request.

By using the electronic device to configure the audio data to be played when the two wireless audio devices are played and the acquired playback request for the audio data, it can be determined whether the two wireless audio playback devices are currently playing different audio data to To achieve the effect of mixing playback. If yes, determine whether each of the wireless audio playback devices is in a preset state.

The preset state indicates a use state of the wireless audio playback device. Specifically, the preset state may be a wearing state, a working state, a connection state, or a usage. The usage indicates a type of audio to be played by the wireless audio playback device, for example, for playback. Audio-only, call voice, or audio in video. Then, if the wireless audio playback device is in a preset state, it means that the user abandons using the wireless audio playback device to listen to the audio data being played, thereby abandoning the auditory effect of the mixed playback.

As an implementation manner, the working status of each of the wireless audio playback devices may be obtained. If the working status of the wireless audio playback device is offline, it is determined that the wireless audio playback device is in a preset state, otherwise, It is determined that the wireless audio playback device is not in a preset state.

Specifically, if the disconnected state is that the connection between the electronic device and the wireless audio playback device is disconnected, the wireless audio playback device may be turned off, and the connection between the electronic device and the wireless audio playback device may be disconnected. The failure of the communication link between the wireless audio playback device and the electronic device results in the connection between the electronic device and the wireless audio playback device being broken.

Specifically, the electronic device sends a beacon to each wireless audio playback device, and determines whether a return result returned by the wireless audio playback device based on the received beacon is received within a preset time. When the return result sent by the wireless audio playback device is obtained, it is determined that the connection between the electronic device and the wireless audio playback device is not disconnected, that is, the working state of the wireless audio playback device is connected, otherwise, the work of the wireless audio playback device is determined The status is offline. If the working state of the wireless audio playback device is offline, it is determined that the wireless audio playback device is in a preset state, and if the working state of the wireless audio playback device is connected, it is determined that the wireless audio playback device is not in a preset state .

In addition, whether the wireless audio playback device is in a preset state can also be determined according to the wearing state and the call status of the wireless audio playback device. For details, refer to the subsequent embodiments.

S302: Use the wireless audio playback device in a preset state as the first wireless audio playback device, and then the audio data played by the first wireless audio playback device during the mixing playback process is the first audio data.

S303: Use the wireless audio playback device that is not in the preset state as the second wireless audio playback device, and then the audio data played by the second wireless audio playback device during the mixing playback process is the second audio data.

For each wireless audio playback device, determine whether it is in a preset state, use the wireless audio playback device in the preset state as the first wireless audio playback device, and use the wireless audio playback device that is not in the preset state as the second wireless audio. A playback device, wherein the audio data played by the first wireless audio playback device during the mixing playback is used as the first audio data, and the audio data played by the second wireless audio playback device during the mixing playback is used as the second audio data That is, the first audio data is used as a reference for the audio data played by the first wireless audio playback device during the mixing playback, and the second audio data is used as the second wireless audio playback device played during the mixing playback. The reference of audio data is not a limitation on the audio data played by the first wireless audio playback device and the second wireless audio playback device.

It should be noted that if the two wireless audio playback devices are not in a preset state, it means that the user is still using the two wireless audio playback devices to listen to the audio played by the mixed audio, and then the method ends or returns to execute S301. In addition, if both wireless audio playback devices are in a preset state, it means that the user has given up using the two wireless audio playback devices to listen to the audio, then the method is ended or the process returns to S301.

S304: Control the second wireless audio playback device to play the first audio data and the second audio data at the same time, so as to implement mixing playback.

Specifically, the second wireless audio playback device is controlled to continue to play the second audio data, and at the same time, the first audio data played by the first wireless audio playback device is also handed over to the second wireless audio playback device to play, so that the user can continue to pass The second wireless audio playback device plays different audio data to achieve a mixing playback effect.

Specifically, the first playback progress of the first audio data played by the first wireless audio playback device is recorded. As an embodiment, when the first wireless audio playback device is determined, it is determined that the two wireless audio playback devices are in a preset state. When the wireless audio playback device is recorded, the time point at this time is recorded as the first time point, the playback progress of the first audio data corresponding to the first time point is determined as the first playback progress, and the second wireless audio playback device is controlled at the same time A specific implementation manner of playing the first audio data and the second audio data is to control the second wireless audio playback device to continue playing the second audio data, and continue to play the first audio data at a first playback progress.

In addition, in order to better achieve the effect of mixing playback, when the first audio data and the second audio data are played, there is a corresponding relationship in time, for example, the two are played at the same time or the two are delayed for a certain time. When the first playback progress lag is acquired, it is determined that during the mixing playback, the second playback progress of the second audio data corresponding to the first playback progress of the second audio data is controlled, and the second wireless audio playback device is controlled to play simultaneously A specific implementation manner of the first audio data and the second audio data is to control the second wireless audio playback device to play the second audio data at a second playback progress while continuing to play the first audio data at a first playback progress.

Taking stereo as an example, and the wireless audio playback device is a wireless headset, the user wears a first wireless headset and a second wireless headset, and the first wireless headset plays the left channel data of the target audio, and the second wireless headset plays the target audio. The right channel data, and the first wireless headset and the second wireless headset simultaneously play the target audio, then the user can listen to the stereo effect of the target audio through the first wireless headset and the second wireless headset. When the user takes off or turns off the first wireless headset or uses the first wireless headset to answer the call, the user can control the second wireless headset through the electronic device to continue playing the left channel data and the right channel data of the target audio to achieve the Two wireless headphones listen to stereo effects.

Among them, as a method, the Android recording generates a pcm file by default, that is, the Android stereo pcm data structure. Assuming that the sampling rate is set to 16K, the recording type is AudioFormat.CHANNEL_IN_STEREO (stereo recording), and the data type is AudioFormat.ENCODING_PCM_16BIT, then The data structure of the pcm file is roughly 2byte left channel, 2byte right channel, 2byte left channel, 2byte right channel .... Therefore, the Android stereo pcm data structure can be split into a left channel audio signal and a right channel. Audio signal, and transmit the left channel audio signal obtained after processing the split signal to the first wireless earphone input user's left ear, and transmit the right channel audio signal obtained after processing the split signal to the second wireless Headphone input into the user's right ear, which can improve the audio playback effect and user experience

In addition, the wireless audio playback device is a wireless headset. The user wears two wireless headsets to play audio data. If one of the wireless headsets is taken off, the other wireless headset is controlled to play different audio data at the same time to achieve the effect of mixing playback. Specifically, please refer to FIG. 5, which shows an audio playback method provided by another embodiment of the present application, which is applied to the above electronic device. Specifically, the method includes S501 to S505.

S501: When two of the wireless audio playback devices are playing different audio data to achieve mixed audio playback, obtain a wearing state of each of the wireless audio playback devices.

Specifically, if the wireless audio playback device is a Bluetooth headset, the Bluetooth headset includes a casing, a Bluetooth module, and a playback module. The Bluetooth module and the playback module are both located in the casing, and the Bluetooth module is used to establish a connection with the electronic device. Connect the relationship and transfer data, etc., and the playback module is used to play the acquired audio data. The case is provided with a contact sensor, which can detect the contact parameters entered by the user when contacting the case of the Bluetooth headset. The contact sensor may be Pressure sensor, proximity light sensor, etc., the contact parameter may be a pressure value or an optical signal intensity value.

When two of the wireless audio playback devices are playing different audio data for mixing playback, the contact parameters of the two Bluetooth headsets are obtained, and based on the contact parameters, the first Bluetooth headset and the second Bluetooth headset are determined. Wearing status of Bluetooth headset.

Further, after obtaining the contact parameters between the two Bluetooth headsets and the user's ear, the first Bluetooth headset in contact with the user's left ear and the second Bluetooth in contact with the user's right ear can be determined from the two Bluetooth headsets. headset. A Bluetooth headset is taken as an example for description. The contact sensor of the Bluetooth headset is fixedly set at the target position of the headset body. When the Bluetooth headset is placed in the left ear of the user, the contact sensor can detect Contact area and contact point of the Bluetooth headset when the Bluetooth headset is placed in the user's right ear, the contact sensor can detect the contact point area and contact point between the user's right ear. Since the setting position of the contact sensor is unchanged, When the Bluetooth headset is switched between the user's left ear and the user's right ear, the contact area and contact point are different. Therefore, after detecting the contact parameters of the Bluetooth headset, the contact parameters and the pre-stored Bluetooth headset can be placed. The contact parameters of the user's left ear and the contact parameters of the Bluetooth headset placed in the user's right ear are compared to determine the placement position of the Bluetooth headset, that is, the Bluetooth headset is determined to be the first Bluetooth headset or the second Bluetooth headset. Similarly, another Bluetooth headset can also be determined as the first Bluetooth headset or the second Bluetooth headset in the above manner, so that it can be determined whether the two Bluetooth headsets are worn on the user's ear based on the contact parameters. The ear, it is determined that the wearing state of the Bluetooth headset is a worn state, and if it is not worn on the user's ear, it is determined that the wearing state of the Bluetooth headset is an unworn state.

In addition, it is also possible to detect whether the first Bluetooth headset and the second Bluetooth headset are worn on the user's ear by the motion trajectory, and specifically detect the motion trajectory of the first Bluetooth headset and the motion trajectory of the second Bluetooth headset, respectively.

As a method, the Bluetooth headset further includes an acceleration sensor and / or a gyroscope, and the acceleration sensor and / or the gyroscope is disposed in the headset body, and is configured to detect the motion trajectory of the Bluetooth headset and send the detected motion trajectory. To the electronic device connected to it, use the power supply device to detect the movement track of the Bluetooth headset. Specifically, the movement track of the first Bluetooth headset can be detected by a first acceleration sensor provided in the first Bluetooth headset and sent to the electronic device, and the second Bluetooth headset can be detected by a second acceleration sensor provided in the second Bluetooth headset. The motion trajectory of the first Bluetooth headset and the second trajectory of the second Bluetooth headset are monitored separately.

Taking the gyroscope as an example, according to the gyroscope's axiality and the known preset attitude of the Bluetooth headset with respect to the rotation axis direction of the gyroscope, when a difference occurs between the attitude of the Bluetooth headset and the preset attitude, pitching occurs. , Yaw or roll movement in a certain direction, because the rotation axis of the gyroscope remains the same direction, it is possible to detect the change in the angle relationship between the Bluetooth headset lever with respect to the rotation axis and the angle relationship between the preset attitude and the rotation axis. Determine the attitude change of the Bluetooth headset, and determine the movement track of the Bluetooth headset.

The wearing state of the two Bluetooth headsets is determined based on the motion trajectories of the two Bluetooth headsets.

In this embodiment, after detecting the motion trajectory of the first Bluetooth headset through an acceleration sensor and / or a gyroscope provided in the headset body of the first Bluetooth headset, it is determined whether the first Bluetooth headset is detached from the user based on the motion trajectory. For the left ear, it can be understood that when the motion trajectory of the first Bluetooth headset has a significant radian change, it can be considered that the first Bluetooth headset is detached from the user's left ear. When the motion trajectory of the first Bluetooth headset has no obvious radian change It can be considered that the first Bluetooth headset is not separated from the left ear of the user.

In this embodiment, after detecting a motion trajectory of the second Bluetooth headset through an acceleration sensor and / or a gyroscope provided in the headset body of the second Bluetooth headset, it is determined whether the second Bluetooth headset is detached from the user based on the motion trajectory.
