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.

As users have higher and higher requirements for electronic devices, in order to meet user needs and provide convenience to users, electronic devices have started to support playing audio data, such as playing audio, playing video, voice chat, video chat, and so on. Among them, the audio architecture of an electronic device is similar to that of a computer, and is mainly completed by a processor and a built-in audio CODEC (codec). Specifically, after receiving the input of audio data, the processor converts it into an I2S signal, transmits it to a CODEC, converts it into an analog signal, and then plays it.

Further, the electronic device may be connected to an external audio playback device and play audio data through the audio playback device. Specifically, the audio playback device may receive audio data transmitted from the electronic device and play the audio data. Audio playback devices may include headphones, speakers, and on-board equipment. In many cases, electronic devices and external audio playback devices need to use a network to perform data transmission. For example, electronic devices and audio playback devices need to use a wireless fidelity (WiFi) connection for data transmission, or electronic devices and The audio playback device needs to use Bluetooth (BT) connection for data transmission, etc. Optionally, under normal circumstances, the electronic device can be connected to the audio playback device via Bluetooth, and the audio data is transmitted to the audio playback device via Bluetooth for playback. .

Specifically, the current electronic device 100 generally has a Bluetooth (BT) module. The Bluetooth module may refer to a chip basic circuit set with integrated Bluetooth function, and is used for wireless network communication. Further, the electronic device 100 can perform a Bluetooth connection with a Bluetooth device (such as an audio playback device such as a Bluetooth headset, a Bluetooth speaker, and a video playback device such as a projector or a television) through a Bluetooth module. A Bluetooth headset is used as an example, as shown in FIG. 1 In one case, the Bluetooth headset includes a first Bluetooth headset 510 and a second Bluetooth headset 520, and the electronic device 100 establishes a communication link with the first Bluetooth headset 510 and the second Bluetooth headset 520 based on the aforementioned wireless communication protocol, respectively. . Furthermore, as shown in FIG. 2, the electronic device 100 may directly propose a communication link with the first Bluetooth headset 510 based on the foregoing wireless communication protocol, and then the first Bluetooth headset 510 and the second Bluetooth headset 520 may be based on the foregoing wireless communication. The communication protocol suggests a communication link. The wireless communication protocol may include a Wlan protocol, a Bluetooth protocol, or a ZigBee protocol.

However, when the current electronic device performs audio data transmission with two Bluetooth headsets separately, the transmitted audio data is fixed and both are mixed sounds, that is, the audio data transmitted to the two Bluetooth headsets for the Bluetooth headsets placed in the left ear The audio data is the same as that transmitted to the two Bluetooth headphones for placing in the user's right ear, the sound effect is poor, and the user experience is not good.

In view of the above problems, the inventor has discovered through long-term research and proposed the audio transmission method, device, electronic device and storage medium provided in the embodiments of the present application. The audio channels are established respectively by the electronic device and the left and right Bluetooth headphones, and the left and right Channel audio signals and right channel audio signals to left and right Bluetooth headsets to improve music playback and user experience. The specific audio transmission method is described in detail in the subsequent embodiments.

Examples

Please refer to FIG. 3, which is a schematic flowchart of an audio transmission method according to an embodiment of the present application. The audio transmission method is used to establish an audio channel between the electronic device and the left and right Bluetooth headsets, and respectively transmit the left channel audio signal and the right channel audio signal to the left and right Bluetooth headsets to improve the music playback effect and the user experience. In a specific embodiment, the audio transmission method is applied to an audio transmission device 200 as shown in FIG. 8 and an electronic device 100 (FIG. 10) configured with the audio transmission device 200. In the following, an electronic device is taken as an example to describe the specific process of this embodiment. Of course, it can be understood that the electronic device applied in this embodiment may be a smart phone, a tablet computer, a wearable electronic device, a vehicle-mounted device, a gateway, etc. This is not specifically limited. The process shown in FIG. 3 will be described in detail below. The audio transmission method may specifically include the following steps:

Step S110: When the electronic device and the two Bluetooth headsets are in a connected state, the use states of the two Bluetooth headsets are respectively acquired.

In this embodiment, the connection state between the electronic device and the two Bluetooth headsets is first detected. It can be understood that the connection state between the electronic device and the two Bluetooth headsets may include being in a connected state and not being in a connected state. Among them, not in the connected state includes the unconnected state and the connected state. As a method, the connection status between the electronic device and the two Bluetooth headsets can be detected separately, that is, the connection status between the electronic device and one of the two Bluetooth headsets is detected, and the electronic device and the two Bluetooth headsets are detected. The connection status of another Bluetooth headset among the two Bluetooth headsets is detected. Understandably, the detection result may include at least the electronic device and the two Bluetooth headsets are connected, the electronic device and the two Bluetooth headsets are not connected, the electronic device and one of the two Bluetooth headsets are connected, and the The other is not connected, and is not limited here.

As a method, whether the electronic device is connected to the two Bluetooth headsets can be determined by viewing the status value of the electronic device. Specifically, when the electronic device is connected to a Bluetooth headset, a first status value is returned. When the electronic device is connected to two Bluetooth headsets, two first status values are returned; when the electronic device is disconnected from one Bluetooth headset, a second status value is returned. When the electronic device is disconnected from two Bluetooth headphones, Two second status values are returned, so that it can be determined whether the electronic device is in a connected state with the two Bluetooth headsets by detecting the first status value and the second status value. As another method, the Android system sends a broadcast when a Bluetooth headset is connected or disconnected, so an electronic device can monitor the broadcast to determine whether the electronic device is in a connected state with the two Bluetooth headsets.

In one embodiment, when it is determined that the electronic device is connected to two Bluetooth headsets at the same time, the usage states of the two Bluetooth headsets are obtained separately. Among them, as the first method, the use status of the two Bluetooth headsets can be determined by judging whether the two Bluetooth headsets transmit audio data. It can be understood that when the Bluetooth headset is detected to be transmitting audio data, it can indicate that the Bluetooth headset is in use. State, when it is detected that the Bluetooth headset is not transmitting audio data, it can indicate that the Bluetooth headset is in a non-use state. For example, when it is detected that both Bluetooth headsets are transmitting audio data, it indicates that both Bluetooth headsets are in use; when it is detected that both Bluetooth headsets are not transmitting audio data, it indicates that both Bluetooth headsets are in an unused state; When it is detected that one of the two Bluetooth headsets is transmitting audio data and the other headset is not transmitting audio data, it indicates that one Bluetooth headset is in use and the other Bluetooth headset is in non-use.

As the second method, the use status of the two Bluetooth headsets can be determined by determining whether the two Bluetooth headsets are placed on the user's ears. It is understandable that when the Bluetooth headsets are detected on the user's ears, the user can be considered Audio data is being received through the Bluetooth headset to indicate that the Bluetooth headset is in use. When it is detected that the Bluetooth headset is not placed on the user's ear, it can be considered that the user has not received audio data through the Bluetooth headset, indicating that the Bluetooth headset is in a non-use state. For example, when it is detected that two Bluetooth headsets are placed in the user's ear, that is, one Bluetooth headset is placed in the user's left ear and the other Bluetooth headset is placed in the user's right ear, it indicates that both Bluetooth headsets are in use; when it is detected, When two Bluetooth headsets are not placed on the user's ear, it indicates that both Bluetooth headsets are not in use; when one of the two headsets is detected as being placed on the user's ear, the other Bluetooth headset is not placed on the user's ear It indicates that one Bluetooth headset is in use and the other Bluetooth headset is not in use.

Of course, this application may also include other methods for judging the use status of the two Bluetooth headsets, which are not repeated here.

Step S120: When the two Bluetooth headsets are both placed on the user's ear, determine a first Bluetooth headset placed on the user's left ear and a second Bluetooth headset placed on the user's right ear.

In this embodiment, optionally, it is determined whether the two Bluetooth headsets are in a use state by judging whether the two Bluetooth headsets are placed on the user's ears. When both the Bluetooth headsets are placed on the user's ears, One of the two Bluetooth headsets is placed on the user's left ear, the other Bluetooth headset is placed on the user's right ear, and both the Bluetooth headset placed on the user's left ear and the Bluetooth headset placed on the user's right ear are in use, further As a method, the Bluetooth headset placed in the left ear of the user among the two Bluetooth headsets is determined as the first Bluetooth headset, and the Bluetooth headset placed in the right ear of the two Bluetooth headsets is determined as the second Bluetooth headset. It is noted that the first Bluetooth headset and the second Bluetooth headset have no primary and secondary differences, and are only used to distinguish between being placed on the user's left ear and being placed on the user's right ear.

Step S130: transmitting the left channel audio signal of the electronic device to the first Bluetooth headset, and transmitting the right channel audio signal of the electronic device to the second Bluetooth headset.

In this embodiment, the electronic device establishes an audio channel with the first Bluetooth headset and the second Bluetooth headset separately, that is, the electronic device can transmit audio data through the audio channel with the first Bluetooth headset. To the first Bluetooth headset, and audio data can be transmitted to the second Bluetooth headset through an audio channel with the second Bluetooth headset.

Further, after the first Bluetooth headset and the second Bluetooth headset are determined, the stereo audio data to be transmitted in the electronic device may be split to obtain a left channel audio signal and a right channel audio signal. 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 the left channel audio signal obtained after processing the split signal is transmitted to the first Bluetooth headset input user's left ear, and the right channel audio signal obtained after processing the split signal is transmitted to the second Bluetooth The headset is input to the user's right ear, which can improve the audio playback effect and user experience.

In the audio transmission method provided by an embodiment of the present application, when an electronic device and two Bluetooth headsets are in a connected state, the usage statuses of the two Bluetooth headsets are obtained respectively. When both Bluetooth headsets are placed in the user's ear, two are determined. The first Bluetooth headset placed in the left ear of the user and the second Bluetooth headset placed in the right ear of the user transmit the left channel audio signal of the electronic device to the first Bluetooth headset, and the right channel audio of the electronic device The signal is transmitted to the second Bluetooth headset, so that the electronic device and the left and right Bluetooth headsets respectively establish an audio channel, and respectively transmit the left channel audio signal and the right channel audio signal to the left and right Bluetooth headsets, improving the music playback effect and the user experience.

Please refer to FIG. 4, which is a schematic flowchart of an audio transmission method according to another embodiment of the present application. The audio transmission method is applied to the above-mentioned electronic device, in which both Bluetooth headsets include a headphone body and a contact sensor provided on the headphone body. The process shown in FIG. 4 will be described in detail below. The audio transmission method It can include the following steps:

Step S210: When the electronic device and the two Bluetooth headsets are in a connected state, the use states of the two Bluetooth headsets are obtained respectively.

The contact sensor is disposed on an outer surface of the headset body. When the Bluetooth headset is placed on a user's ear, The contact sensor is in contact with the user's ear to generate a contact signal. Specifically, when both Bluetooth headsets are placed on the user's ears, the two touch sensors provided on the two headset bodies can be used to detect the contact parameters with the user's ears, respectively. It is understandable that the two A contact sensor on the first headset body detects a contact parameter between the first Bluetooth headset and the user's ear, and a contact sensor provided on the second headset body detects a contact parameter between the second Bluetooth headset and the user's ear.

The contact parameter may include at least a contact area and a contact point, that is, the contact parameter may be a contact area, a contact point, or both. Therefore, the contact area and / or contact point between the two Bluetooth headsets and the user's ear can be detected by the touch sensor.

Step S230: Determine the first Bluetooth headset and the second Bluetooth headset based on the contact parameters.

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 a target position of the headset body. When the Bluetooth headset is placed in the left ear of the user, the contact sensor can detect the distance between the Bluetooth sensor and the left ear of the user. 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 the first Bluetooth headset and the second Bluetooth headset among the two Bluetooth headsets can be determined based on the contact parameter. Bluetooth earphone.

Step S240: transmitting the left channel audio signal of the electronic device to the first Bluetooth headset, and transmitting the right channel audio signal of the electronic device to the second Bluetooth headset.

For a detailed description of step S240, please refer to step S130, and details are not described herein again.

Step S250: Monitor the use state of the first Bluetooth headset and the use state of the second Bluetooth headset, respectively.

Further, during the process of transmitting the left channel audio signal to the first Bluetooth headset and the right channel audio signal to the second Bluetooth headset, the usage status of the first Bluetooth headset and the second Bluetooth headset are monitored separately. The state of use, wherein whether the first Bluetooth headset is always placed on the user's left ear and whether the second Bluetooth headset is always placed on the user's right ear can be monitored. As a method, it is possible to determine whether the first Bluetooth headset is placed in the left ear of the user and whether the second Bluetooth headset is placed in the right ear of the user by monitoring the change of the contact sensor, and details are not described herein again.

Please refer to FIG. 5, which is a schematic flowchart of step S250 of the audio transmission method provided by the embodiment shown in FIG. 4 of the present application. The process shown in FIG. 5 will be described in detail below. The method may specifically include the following steps:

Step S251: Monitor the movement track of the first Bluetooth headset and the movement track 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.

Step S252: Determine whether the first Bluetooth headset is detached from the left ear of the user based on the movement track of the first Bluetooth headset.

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.

Step S253: Determine whether the second Bluetooth headset is detached from the right ear of the user based on the movement track of the second Bluetooth headset.

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. For the right ear, it can be understood that when the motion trajectory of the second Bluetooth headset has a significant radian change, it can be considered that the second Bluetooth headset is detached from the user's right ear. When the motion trajectory of the second Bluetooth headset has no obvious radian change It can be considered that the second Bluetooth headset is not separated from the user's right ear.

Step S260: When the first Bluetooth headset is separated from the left ear of the user and the second Bluetooth headset is placed on the right ear of the user, the stereo audio signal of the electronic device is transmitted to the second Bluetooth headset.

Further, when it is detected that the first Bluetooth headset is detached from the user's left ear and the second Bluetooth headset is placed for the right ear, indicating that the first Bluetooth headset is in a non-use state and the second Bluetooth headset is in a use state, the electronic The stereo audio signal of the device is transmitted to the second Bluetooth headset, so that the audio signal input to the user's ear is a stereo audio signal to ensure the music playback effect and user experience. Understandably, at this time, the first Bluetooth headset is in a non-use state, and the electronic device does not need to transmit audio signals to the first Bluetooth headset. Therefore, the connection between the electronic device and the first Bluetooth headset can be disconnected, and the control can be controlled. The first Bluetooth headset sleeps or is turned off to save power consumption and power of the electronic device and the first Bluetooth headset.

Step S270: When the first Bluetooth headset is placed on the left ear of the user and the second Bluetooth headset is detached from the right ear of the user, the stereo audio signal of the electronic device is transmitted to the first Bluetooth headset.

Similarly, when it is detected that the second Bluetooth headset is detached from the user's right ear and the first Bluetooth headset is placed for the left ear, indicating that the first Bluetooth headset is in use state and the second Bluetooth headset is in non-use state, the electronic The stereo audio signal of the device is transmitted to the first Bluetooth headset, so that the audio signal input to the user's ear is a stereo audio signal to ensure the music playback effect and user experience. Understandably, at this time, the second Bluetooth headset is not in use, and the electronic device does not need to transmit audio signals to the second Bluetooth headset. Therefore, the connection between the electronic device and the second Bluetooth headset can be disconnected and the first The second Bluetooth headset sleeps or shuts down to save power consumption and power of the electronic device and the second Bluetooth headset.

In the audio transmission method provided by another embodiment of the present application, when an electronic device and two Bluetooth headsets are in a connected state, the usage statuses of the two Bluetooth headsets are obtained, and when both Bluetooth headsets are placed on the user's ears, respectively, The contact parameters between the two touch sensors and the user's ear. Based on the contact parameters, the first Bluetooth headset and the second Bluetooth headset are determined, and the left channel audio signal of the electronic device is transmitted to the first Bluetooth headset. The channel audio signal is transmitted to the second Bluetooth headset, and the usage status of the first Bluetooth headset and the second Bluetooth headset are monitored separately. When the first Bluetooth headset is separated from the user's left ear and the second Bluetooth headset is placed in the user's right ear, The stereo audio signal of the electronic device is transmitted to the second Bluetooth headset. When the first Bluetooth headset is placed in the user's left ear and the second Bluetooth headset is separated from the user's right ear, the stereo audio signal of the electronic device is transmitted to the first Bluetooth headset. Compared with the audio transmission method shown in FIG. 3, in this embodiment, the left and right can be determined by the contact parameters detected by the touch sensor. The earphone converts the audio signal into a stereo audio signal when one of the earphones is separated from the user's ear, and transmits it to the other earphone placed in the user's ear to ensure the user's audio experience.

Please refer to FIG. 6, which is a schematic flowchart of an audio transmission method according to another embodiment of the present application. This method is applied to the above-mentioned electronic device, where both Bluetooth headsets include a headset body and a contact sensor provided on the headset body. The following describes the process shown in FIG. 6 in detail. The audio transmission method may specifically include: The following steps:

Step S310: When the electronic device and the two Bluetooth headsets are in a connected state, the use states of the two Bluetooth headsets are obtained respectively.

For a detailed description of step S310, refer to step S210, and details are not described herein again.

Step S320: When the two Bluetooth headsets are both placed on the ear of the user, obtain the contact areas between the two touch sensors and the ear of the user.

In this embodiment, both Bluetooth headsets include a headset body and a contact sensor, and the contact sensor is disposed on the headset body. The contact sensor is disposed on an outer surface of the headset body. When the Bluetooth headset is placed on a user's ear, The contact sensor is in contact with the user's ear to generate a contact signal. Specifically, when the two Bluetooth headsets are both placed on the user's ears, the contact area with the user's ears can be detected by two contact sensors provided on the two headset bodies. It is understandable that the two A contact sensor on the first headset detects a contact area between the first headset and a user's ear, and a contact sensor provided on the second headset detects a contact area between the second headset and the user's ear.

Step S330: Determine the first Bluetooth headset and the second Bluetooth headset based on the contact area.
