[0003] Bluetooth headsets are unencumbered by wires and unrestricted by the interfaces of mobile phones and tablets. Their strong compatibility makes them popular with consumers. Headphone manufacturers have modified the output speakers of Bluetooth headsets to prevent sound leakage and protect the privacy of their voice output. However, due to the distance between the Bluetooth headset and the user's voice input, when a user inputs into the Bluetooth headset, the voice content is not only collected by the Bluetooth headset but also spreads to the surrounding area. This leaves the user's input voice unprotected, leading to privacy breaches. Technical issues

[0004] The embodiments of the present application provide an audio transmission method, device, terminal and readable storage medium to solve the problem in the prior art that the voice input by the user into the Bluetooth headset is not protected, resulting in the leakage of user privacy.

The first device receives the first audio data sent by the second device, that is, the second device transmits the first audio data to the first device. The remaining functions of the first device can be used normally. By controlling the second device to shorten the distance between the second device and the user's voice position, the possibility of the collected audio spreading to the surrounding area is reduced, thereby protecting the user's privacy.

[0039] In order to illustrate the technical solution described in this application, specific embodiments are provided below.

[0040] Referring to Figure 1, Figure 1 is a flowchart of an audio transmission method provided by an embodiment of the present application. As shown in Figure 1, an audio transmission method is applied to a first device, and the method includes the following steps:

[0041] Step 101: When detecting that a second device is powered on, establish a communication connection with the second device.

[0042] Specifically, in order to protect the voice content input by the user into the Bluetooth headset and ensure that the user's privacy is not leaked, this application proposes an audio transmission method, which is applied to the first device. The first device is a wireless headset, such as a head-mounted Bluetooth headset, a neck-hanging Bluetooth headset, a true wireless Bluetooth headset, and other Bluetooth headsets, as well as other wireless headsets. The second device has an audio acquisition function and can be a mobile device with an audio acquisition function. In order to facilitate portability, it is usually designed as a wearable device, such as a ring, a bracelet, or a necklace.

[0043] Specifically, as shown in Figure 2, Figure 2 is a device communication relationship diagram provided by the present application. It can be seen from Figure 2 that there is a communication connection between the first device and the second device, and there is also a communication connection between the first device and the external device. The external device refers to a terminal device such as a mobile phone, tablet and computer that can establish a communication connection with the first device. The second device can only establish a communication connection with the first device and cannot establish a communication connection with the external device. In addition to establishing a communication connection with the second device, the first device can also establish a communication connection with the external device. That is, the second device is an accessory of the first device. There is direct communication between the first device and the second device, and there is direct communication between the first device and the external device. This setting makes the operation interface of the external device only display the first device, and the interface is simple and easy to manage.

[0044] Specifically, the second device is an accessory to the first device. Therefore, before shipment or user use, the first and second devices must be bound to each other. This means that permission to establish a communication connection between the first and second devices is enabled. Binding the devices prevents random device connections from causing communication confusion.

[0045] It should be noted that the second device in this application refers to a device that has a binding relationship with the first device.

[0046] Specifically, after the first device is powered on, it sends a signal to the surrounding space to detect whether the second device is powered on. If the second device is detected to be powered on, a communication connection is established with the second device. The detection and communication connection establishment process occurs very quickly, facilitating subsequent user use.

[0047] Specifically, the communication connection mode between the first device and the second device may be Bluetooth Low Energy (BLE) or wireless communication technology (WIFI).

[0048] Step 102: Generate a privacy protection request in response to a first user operation; the privacy protection request is used to instruct the first device to turn off an audio collection function, and to instruct the second device to turn on the audio collection function.

[0049] The first user operation specifically refers to an operation performed by the user on the first device to trigger privacy protection. The privacy protection request is used to instruct the first device to turn off the audio collection function and to instruct the second device to turn on the audio collection function.

[0050] Specifically, if the user performs the first user operation on the first device, such as pressing the privacy protection button, the first device generates the privacy protection request. This can be further categorized as: pressing and releasing the button generates the privacy protection request, activating the privacy protection function; pressing and releasing the button generates the privacy protection request, but the privacy protection function takes effect only if the button is pressed.

[0051] Specifically, after generating the privacy protection request in response to the first user operation, the method further includes: based on the privacy protection request, the first device turns off the audio collection function.

[0052] Specifically, after the first device generates the privacy protection request, the first device adjusts the function of the device itself according to the privacy protection request, that is, turns off the audio collection function of the first device.

[0053] Step 103: Send the privacy protection request to the second device, instructing the second device to enable the audio collection function.

[0054] Specifically, after generating the privacy protection request, the first device sends the privacy protection request to the second device via the communication connection. After receiving the privacy protection request, the second device enables the audio collection function of the second device according to the instruction of the privacy protection request.

[0055] Specifically, the generation of the privacy protection request, the sending of the privacy protection request, and the adjustment of the collection functions of the first device and the second device according to the privacy protection request also occur within a very short period of time.

[0056] Specifically, after the audio collection function of the second device is enabled, audio collection is no longer the responsibility of the first device, but is instead performed by the second device. The second device can then collect audio using an audio collection device included in the second device, such as a microphone.

[0057] Specifically, traditional Bluetooth headsets have a speaker and a microphone for outputting audio from external devices and collecting audio for the external device. A drawback of traditional Bluetooth headsets is that the headset is some distance away from the user's voice source. When a user inputs audio into the headset, the audio is not only picked up by the headset's microphone but also diffuses to the surrounding area, allowing people around the user to hear it or nearby devices to pick it up. This leaves the audio input into the headset unprotected, leading to privacy breaches.

[0058] Specifically, the first device in this application, i.e., the wireless headset, also has a speaker and a microphone. When the user does not use the privacy protection function, the first device is no different from a traditional Bluetooth headset in terms of usage. The first device in this application also outputs the audio of the external device through the speaker and collects the audio for the external device through the microphone. Here, the microphone of the first device is the audio collection device.

[0059] Specifically, the audio collection function of the first device is turned off, and the audio collection function of the second device is turned on, which means that the privacy protection function is turned on. As mentioned above, the second device may be a removable device. Therefore, after the privacy protection function is turned on, the second device can be moved to the user's voice position to collect audio. By moving, the distance between the microphone of the audio collection device and the user's voice position is reduced. The microphone of the second device and its sound cavity are optimized for low sounds and close to the mouth, such as high sensitivity to pick up low sounds, which can reduce the sound volume while shortening the distance, thereby protecting the user's audio data and preventing the user's privacy from being leaked. In addition, pointing the microphone and its sound cavity in a specific direction can further shield external noise.

[0060] It should be noted that, although the audio collection function of the first device is turned off at this time, other functions of the first device are not affected and can be used normally. For example, the speaker of the first device plays the audio from the external device normally.

[0061] Specifically, the second device can be a removable device such as a ring, a bracelet, and a necklace. This application prefers a ring as the second device. Taking a ring as an example, the second device is introduced. As shown in Figure 3, Figure 3 is a schematic diagram of a second device provided by this application. In Figure 3, the three rectangles in the ring are located on the outside of the ring and are function buttons. When worn, they face the same direction as the back of the hand. The circle is also located on the outside of the ring and is a microphone for collecting audio. When worn, it faces the same direction as the palm. In this way, when the user moves the ring to the user's voice position, such as the mouth, they can also make an open hand covering their mouth as if whispering, further reducing the risk of input audio being leaked. Moreover, the microphone faces the same direction as the palm and makes an open hand covering the mouth as if whispering, which can further block external noise.

[0062] Specifically, the audio collected by the second device is referred to as original audio.

[0063] Specifically, the response between devices is very fast, so the privacy protection function is enabled at the same time as the user's first operation occurs. After the privacy protection function is enabled, if the user triggers a privacy protection revocation request, the privacy protection function is disabled. After the privacy protection revocation request is generated, the first device enables the audio collection function, and the second device disables the audio collection function.

[0064] Specifically, if the privacy protection revocation request is generated by the first device, the first device directly receives the privacy protection revocation request and enables the audio collection function of the first device. Simultaneously, based on the communication connection, the first device sends the privacy protection revocation request to the second device. After receiving the privacy protection request, the second device disables the audio collection function of the second device. The audio is then collected by an audio collection device, such as a microphone, of the first device.

[0065] At this point, the privacy protection function is turned off. The first device directly collects audio and transmits it to the external device.

[0066] Step 104: Receive first audio data sent by the second device.

[0067] Specifically, after the second device collects the original audio, in order to better transmit the original audio, it is necessary to encode the original audio, that is, convert the analog signal into a digital signal to obtain the first audio data, and then send the first audio data to the first device.

[0068] Specifically, the original audio is encoded using audio transmission coding, and the audio transmission coding is subband coding (SBC), advanced audio coding (AAC), low complexity communications codec (LC3) or low-latency high-definition audio codec (LHDC), etc.

[0069] Specifically, the audio transmission encoding used between the first device and the second device is a first encoding, and the audio transmission encoding used between the first device and the external device is a second encoding. After receiving the first audio data sent by the second device, it also includes: determining whether the first encoding and the second encoding are the same; if the first encoding and the second encoding are the same, sending the received first audio data to the external device.

[0070] Specifically, this application defines the audio transmission coding used between the first device and the second device as a first coding, wherein the first coding is a non-customized audio transmission coding such as SBC, AAC, LC3 or LHDC, or a customized audio transmission coding. The audio transmission coding used between the first device and the external device is defined as a second coding, and the second coding is SBC, AAC, LC3 or LHDC, etc.

[0071] Specifically, the second device encodes the collected original audio according to the first encoding to obtain the first audio data, and then the second device can send the first audio data to the first device, thereby realizing the transmission of the original audio.

[0072] Furthermore, after receiving the first audio data sent by the second device, the first device needs to continue to transmit the first audio data backward, that is, send the audio data corresponding to the original audio to the external device. However, before continuing the backward transmission, it is necessary to first determine whether the first encoding and the second encoding are the same. If the first encoding and the second encoding are the same, it means that the external device is able to decode the first audio data and restore it to the original audio. The first device can directly send the received first audio data to the external device.

[0073] Specifically, after determining whether the first encoding and the second encoding are the same, it also includes: if the first encoding and the second encoding are not the same, decoding the first audio data based on the first encoding to obtain the original audio; encoding the original audio based on the second encoding to obtain second audio data; and sending the second audio data to the external device.

[0074] Specifically, if the determination reveals that the first encoding and the second encoding are different, this indicates that the external device cannot decode the first audio data and cannot restore it to the original audio. In this case, the first device decodes the first audio data according to the first encoding to obtain the original audio. The first device then encodes the original audio according to the second encoding to obtain the second audio data. The first device then sends the second audio data to the external device, thereby enabling further transmission of the original audio.

[0075] Optionally, in order to enable the external device to receive higher quality audio, the audio is processed using an audio processing algorithm, including noise reduction, sound enhancement, sound merging, and echo cancellation. The audio processing algorithm can be implemented in any one or more of the first device, the second device, and the external device.

[0076] Specifically, if the audio processing algorithm is implemented in the second device, after the second device collects the original audio, the original audio is first processed by the audio processing algorithm, and then encoded according to the first encoding.

[0077] Specifically, if the audio processing algorithm is implemented in the first device, after the first device receives the first audio data, the first audio data is first decoded according to the first encoding to obtain the original audio, and then the original audio is processed by the audio processing algorithm. After processing, the original audio is encoded according to the first encoding or the second encoding.

[0078] Specifically, if the audio processing algorithm is implemented in the external device, after the external device receives the first audio data or the second audio data, the external device decodes the first audio data according to the first encoding, or decodes the second audio data according to the second encoding to obtain the original audio, and then processes the original audio through the audio processing algorithm to complete the audio quality improvement operation of the original audio.

[0079] In addition, the first device can also receive a function adjustment request sent by the second device. The function adjustment request here does not involve the privacy protection function. The function of the external device is adjusted according to the function adjustment request. Please refer to steps 501 to 503 for the specific implementation process.

[0080] In an embodiment of the present application, when the first device detects that the second device is turned on, a communication connection is established between the first device and the second device. Then, based on the user's first operation, the first device generates a privacy protection request and sends the privacy protection request to the second device through the communication connection. The first device turns off the audio collection function according to the instructions of the privacy protection request, and the second device turns on the audio collection function according to the instructions of the privacy protection request. This operation causes the audio collection end to change, and the second device begins to be responsible for collecting audio. The first device receives the first audio data sent by the second device, that is, the second device transmits the first audio data to the first device. The remaining functions of the first device can be used normally. By controlling the second device to shorten the distance between the second device and the user's voice position, the possibility of the collected audio spreading to the surrounding area is reduced, thereby protecting the user's privacy.

[0081] Referring to Figure 4, Figure 4 is a flowchart of a second method for audio transmission provided by an embodiment of the present application. As shown in Figure 4, an audio transmission method is applied to a second device, and the method includes the following steps:

[0082] Step 401: When it is detected that the first device is powered on, a communication connection is established with the first device.

[0083] Specifically, in order to protect the voice content input by the user into the Bluetooth headset and ensure that the user's privacy is not leaked, this application proposes an audio transmission method, which is applied to the second device. The first device is a wireless headset, such as a head-mounted Bluetooth headset, a neck-hanging Bluetooth headset, a true wireless Bluetooth headset, and other Bluetooth headsets, as well as other wireless headsets. The second device has an audio acquisition function and can be a removable device with an audio acquisition function. In order to facilitate portability, it is usually designed as a wearable device, such as a ring, a bracelet, or a necklace.

[0084] Specifically, in this embodiment, the device communication connection relationship between the first device, the second device, and the external device is the same as that described in step 101. Similarly, the second device is an accessory of the first device, and a binding relationship exists between the first device and the second device, i.e., permission to establish a communication connection has been enabled between the first device and the second device.

[0085] Specifically, after the second device is powered on, it sends a signal to the surrounding space to detect whether the first device is powered on. If the first device is detected to be powered on, a communication connection is established with the first device. Here, the detection process and the communication connection establishment process also occur in a very short time, which is convenient for the user's subsequent use.

[0086] Here, the second device serves as a communication detection device and a request generating device, and the first device serves as a communication detected device and a request receiving device.

[0087] Specifically, the communication connection mode between the first device and the second device may be Bluetooth Low Energy (BLE), Zigbee or wireless communication technology (WIFI).

[0088] Step 402: Generate a privacy protection request in response to a second user operation; the privacy protection request is used to instruct the first device to turn off the audio collection function and instruct the second device to turn on the audio collection function.

[0089] The second user operation specifically refers to an operation performed by the user on the second device to trigger privacy protection. The privacy protection request is used to instruct the first device to turn off the audio collection function and to instruct the second device to turn on the audio collection function.

[0090] Specifically, if the user performs the second user operation on the second device, such as pressing the privacy protection button, the second device generates the privacy protection request. This can be further categorized as: pressing and releasing the button generates the privacy protection request, activating the privacy protection function; pressing and releasing the button generates the privacy protection request, but the privacy protection function takes effect only if the button is pressed.

[0091] Specifically, after the second device generates the privacy protection request, the second device adjusts the function of the device itself according to the privacy protection request, that is, turns on the audio collection function of the second device.

[0092] In addition, the privacy protection request may also be generated by the external device. In the case where the privacy protection request is generated by the external device, the external device sends the privacy protection request to the first device. After receiving the privacy protection request, the first device turns off the audio collection function of the first device. Simultaneously, based on the communication connection, the first device sends the privacy protection request to the second device. After receiving the privacy protection request, the second device turns on the audio collection function of the second device, and the microphone of the second device collects audio.

[0093] It's important to note that if at least one of the first and second devices is not enabled, the privacy protection request will not be generated and the privacy protection feature will not be activated. For example, for an external device, a prompt will pop up stating "No relevant device detected, privacy protection feature not activated!"

[0094] Step 403: Send the privacy protection request to the first device, instructing the first device to disable the audio collection function.

[0095] Specifically, after generating the privacy protection request, the second device sends the privacy protection request to the first device via the communication connection. After receiving the privacy protection request, the first device disables the audio collection function of the first device according to the instruction of the privacy protection request.

[0096] Specifically, similar to the above embodiment, the generation of the privacy protection request, the sending of the privacy protection request, and the functional adjustment of the first device and the second device according to the privacy protection request also occur within a very short period of time.

[0097] Specifically, after the audio capture function of the second device is enabled, audio capture is no longer the responsibility of the first device, but is instead performed by the second device. Audio capture can now be performed using an audio capture device, such as a microphone, included in the second device. The advantages of using the second device for audio capture are described in detail in step 103 and will not be further elaborated here.

[0098] Specifically, with respect to the privacy protection revocation request, if the privacy protection revocation request is generated by the second device, the second device directly receives the privacy protection revocation request and disables the audio collection function of the second device. Simultaneously, based on the communication connection, the second device sends the privacy protection revocation request to the first device. After receiving the privacy protection revocation request, the first device enables the audio collection function of the first device, and the audio is collected by the audio collection device of the first device, such as a microphone.

[0099] Specifically, the privacy protection revocation request may also be generated by the external device. If the privacy protection revocation request is generated by the external device, the external device sends the privacy protection revocation request to the first device. After receiving the privacy protection revocation request, the first device turns on the audio collection function of the first device, and the audio collection device of the first device, such as a microphone, collects audio. Simultaneously, based on the communication connection, the first device sends the privacy protection revocation request to the second device. After receiving the privacy protection revocation request, the second device turns off the audio collection function of the second device.

[0100] At this point, the privacy protection function is turned off. The first device directly collects audio and transmits it to the external device.

[0101] Step 404: Encode the collected original audio to obtain first audio data.

[0102] Specifically, the second device starts to collect audio and collects the original audio. After the second device collects the original audio, in order to better transmit the original audio, it needs to encode the original audio, that is, convert the analog signal into a digital signal to obtain the first audio data.

[0103] Specifically, the audio transmission encoding used between the first device and the second device is a first encoding, and the encoding processing of the collected original audio to obtain the first audio data includes: encoding the collected original audio based on the first encoding to obtain the first audio data.

[0104] Specifically, the content of the first encoding is described in the above embodiment. The second device encodes the collected original audio according to the first encoding to obtain the first audio data.

[0105] Step 405: Send the first audio data to the first device.

[0106] Specifically, the first audio data obtained after encoding processing is sent to the first device.

[0107] Furthermore, the first device can receive the first audio data sent by the second device. The subsequent audio data transmission process is the same as the implementation process of step 104 in the above embodiment, and will not be repeated here.

[0108] In an embodiment of the present application, when the second device detects that the first device is turned on, a communication connection is established between the second device and the first device. Then, based on the user's second operation, the second device generates a privacy protection request and sends the privacy protection request to the first device through the communication connection. The second device turns on the audio acquisition function according to the instructions of the privacy protection request, and the first device turns off the audio acquisition function according to the instructions of the privacy protection request. This operation causes a change in the audio acquisition end, and the second device begins to be responsible for collecting audio. The second device collects the original audio, and after encoding processing, transmits the first audio data corresponding to the original audio to the first device. Without affecting the use of other functions of the first device, the distance between the second device and the user's voice position can be shortened by controlling the second device, reducing the possibility of the collected audio spreading to the surrounding area, thereby protecting the user's privacy.

[0109] Referring to Figure 5, Figure 5 is a flowchart of a third embodiment of an audio transmission method provided by the present application. As shown in Figure 5, an audio transmission method is applied to a second device, and the method includes the following steps:

[0110] Step 501: When it is detected that a first device is powered on, a communication connection is established with the first device.

[0111] The implementation process of this step is the same as the implementation process of step 401 in the aforementioned embodiment, and will not be repeated here.

[0112] Step 502: Generate a function adjustment request in response to a third user operation; the function adjustment request is used to instruct the first device to adjust the function of the external device.

[0113] Specifically, in addition to providing audio capture for the privacy protection function, the second device can also adjust the functions of the external device, such as answering and hanging up calls, increasing and decreasing the volume, swiping up and down to switch screens, and taking photos and videos.

[0114] Specifically, as long as the second device and the first device successfully establish a communication connection, the second device can adjust the function of the external device through the first device.

[0115] Specifically, the third user operation refers to an operation performed by a user to trigger a function adjustment. The function adjustment herein does not involve the privacy protection function. The third user operation is an operation performed by the user on the second device, such as a touch or click. There are multiple types of third user operations, and different third user operations correspond to different function adjustment purposes, but the implementation process is basically the same.

[0116] Specifically, in response to the third user operation, the second device generates the function adjustment request, where the function adjustment request is used to instruct the first device to adjust the function of the external device.

[0117] Step 503: Send the function adjustment request to the first device, instructing the first device to adjust the function of the external device based on the function adjustment request.

[0118] Specifically, after the second device generates the function adjustment request, the second device sends the function adjustment request to the first device.

[0119] Specifically, here the request is sent to the first device, which performs subsequent operations, rather than the second device directly adjusting the external device, to avoid functional disorders caused by an increase in devices.

[0120] Specifically, after the first device receives the function adjustment request, it directly adjusts the function of the external device according to the function adjustment request, that is, the first device parses the function adjustment request and adjusts the function of the external device. The adjustment process is the same as the process of directly adjusting the function of the external device through the first device.

[0121] Specifically, the first device, especially when the first device is a true wireless Bluetooth headset, is small in size, with few clickable buttons and touchable positions. Often, some operations such as controlling the volume, previous song, and next song require double-clicking, triple-clicking, double-clicking and long pressing, and other continuous operations to implement, which makes the user operation complicated and unfriendly.

[0122] The present application can expand the functions of the first device and simplify the control operations by providing an accessory for the first device, that is, providing the second device. At the same time, since the second device is a movable device, the user can operate the second device intuitively and at close range, that is, indirectly adjust the function of the external device by clicking or touching the second device, without the user having to touch the first device, and is less likely to cause erroneous operations.

[0123] Specifically, as previously mentioned, the second device is an accessory to the first device, and only the first device is displayed on the external device's interface. However, the effect of the function adjustment request triggered by the second device is the same as the effect of the adjustment directly made by the first device on the external device. For example, if you press the volume up button on the second device, the external device will see the same effect as if you pressed the volume up button on the first device.

[0124] In an embodiment of the present application, after the second device establishes a communication connection with the first device, based on the user's third operation, the second device generates a function adjustment request and sends the function adjustment request to the first device, instructing the first device to adjust the function of the external device according to the function adjustment request, to facilitate the user to make adjustments.

[0125] The embodiment of the present application also provides an audio transmission device.

[0126] Optionally, the audio transmission apparatus includes a first device communicatively connected to a second device; the first device is used to execute the first audio transmission method disclosed in the embodiment of the present application.

[0127] Alternatively, the application sharing device includes the second device communicatively connected to the first device; the second device is used to execute the second and third audio transmission methods disclosed in the embodiments of the present application.

For portability, it is usually designed as a wearable device, such as a ring, bracelet, or necklace.
