[0042] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0043] The sound signal processing method provided in the embodiment of the present application can be applied to Figure 1 In the application environment shown. Among them, the terminal 120 communicates with the server 130 through the network. The data storage system can store the data that the server 130 needs to process. The data storage system can be integrated on the server 130, or it can be placed on the cloud or other network servers. The terminal 120 can communicate with the wireless headset 110 based on Bluetooth technology. The wireless headset 110 can send the audio signal to one or more other nearby wireless headsets 111 in a broadcasting manner. Among them, the terminal 120 can be, but is not limited to, various personal computers, laptops, smart phones, tablet computers, Internet of Things devices and portable wearable devices. The Internet of Things devices can be smart speakers, smart TVs, smart air conditioners, smart car devices, projection devices, etc. Portable wearable devices can be smart watches, smart bracelets, head-mounted devices, etc. The head-mounted devices can be virtual reality (VR) devices, augmented reality (AR) devices, smart glasses, etc. The server 130 can be an independent physical server, a server cluster or distributed system composed of multiple physical servers, or a cloud server that provides cloud computing services. The wireless earphone 110 may be implemented based on an existing True Wireless Stereo (TWS) earphone, a headphone, or the like.

[0044] In an exemplary embodiment, Figure 2 As shown, a sound signal processing method is provided, and the method is applied to Figure 1 The wireless headset 110 in the embodiment is taken as an example to illustrate, and the method includes the following steps S202 to S208. Among them:

[0045] Step S202 : in response to detecting an activation operation of the first target function, obtaining a user's voice signal.

[0046] The operation of opening the first target function may be a touch operation on the touch-sensitive area / pressure-sensitive control on the surface of the wireless headset 110, a voice command containing identification information of the first target function, an opening command of the first target function sent by the terminal, etc. The touch operation may include gesture operations such as single-click, double-click, and long-press. The wireless headset 110 may recognize and execute the voice command through a built-in voice recognition component.

[0047] Exemplarily, when the user needs to give an explanation, the first target function of the wireless headset 110 can be turned on. At this time, the wireless headset 110 can continuously obtain the sound signal of the user's explanation through its own sound collection component (for example, a microphone, a bone conduction sensor, etc.).

[0048] Step S204: generating a first broadcast signal based on the user's voice signal.

[0049] Optionally, the wireless headset 110 can receive a sound signal sent by other devices, synthesize the user's sound signal with the sound signal sent by other devices, and generate a first broadcast signal. The sound signal sent by other devices may include a pre-stored audio file, an audio stream transmitted in real time over the network, a second broadcast signal broadcast by other wireless headsets, etc.

[0050] Optionally, the wireless headset 110 can suppress the noise in the user's voice signal through an internally integrated digital signal processing (DSP) component to generate the first broadcast signal. The digital signal processing component can be used to execute an environmental noise cancellation (ENC) algorithm, an active noise cancellation (ANC) algorithm, etc.

[0051] Step S206: broadcast the first broadcast signal so that other wireless headsets within the effective broadcast range of the wireless headset receive and play the first broadcast signal.

[0052] The effective broadcast range of the wireless headset 110 may be determined according to the signal transmission power, antenna design, etc. of the wireless headset 110. It is understandable that there may be one or more other wireless headsets within the effective broadcast range of the wireless headset 110. In response to detecting the activation operation of the second target function, the other wireless headsets may receive and play the first broadcast signal.

[0053] For example, the wireless headset 110 may send the first broadcast signal to other nearby wireless headsets based on low-power audio Bluetooth technology, BIS (Broadcast Isochronous Streams) mode, or the like.

[0054] Step S208, in response to detecting the activation operation of the second target function, receiving and playing a second broadcast signal; the second broadcast signal is broadcast by other wireless headphones.

[0055] Among them, the turning on operation of the second target function may include the turning off operation of the first target function. For example, the second target function and the first target function can be switched by long pressing / double clicking / triple clicking or other methods that are not easily triggered by mistake. Alternatively, the second target function and the first target function can be turned on at the same time without interfering with each other. Other wireless headphones can obtain the user's sound signal in response to detecting the turning on operation of the first target function; generate a second broadcast signal based on the sound signal; broadcast the second broadcast signal, so that the wireless headset 110 receives and plays the second broadcast signal in response to detecting the turning on operation of the second target function.

[0056] For example, a new input path for broadcast signals can be added to the wireless headset 110. When the user needs to receive explanation information, the second target function of the wireless headset 110 can be turned on. At this time, the wireless headset 110 can switch from the input path of the current audio source to the input path of the broadcast signal, and transmit the broadcast signal to the speaker of the wireless headset 110 for playback.

[0057] In some application scenarios, when a specific person is required to give an explanation and other people receive the explanation information, the relevant person can wear a wireless headset that supports the first target function and the second target function to participate in the broadcasting / receiving of the explanation information. At the same time, one or more people can broadcast the explanation information, and other people can choose to receive one or more of the broadcast signals for playback.

[0058] In the above-mentioned sound signal processing method, by integrating the explanation and receiving functions in the wireless headset, when it is detected that the explanation function (the first target function) is turned on, the user's voice will be collected in real time and processed and then broadcast, so that the explanation information can be transmitted to one or more wireless headsets with a receiving function in a broadcast manner. When it is detected that the receiving function (the second target function) is turned on, the received broadcast is played, so that the explanation information can be obtained in a timely and convenient manner. It is suitable for explanation scenarios with multiple participants and the participants can flexibly switch between the roles of explainer and receiver.

[0059] In an exemplary embodiment, Figure 3 As shown, the above step S204:

[0060] Step S2041, receiving a sound signal sent by a terminal.

[0061] The sound signal sent by the terminal may include music, sound effects, background sounds, pre-collected explanation voices, etc. For example, when the user is explaining, other sound signals for assisting the explanation may be sent to the wireless headset 110 through the terminal as needed. For example, when explaining artworks, music of the corresponding historical period may be superimposed on the real-time explanation. When explaining product functions, the operation sound effects of the functions may be superimposed on the real-time explanation.

[0062] Step S2042: synthesize the user's voice signal and the voice signal sent by the terminal to obtain a first broadcast signal.

[0063] Exemplarily, in response to receiving the activation instruction of the third target function sent by the terminal, the wireless headset 110 may receive the sound signal sent by the terminal, decode it into an audio format that can be synthesized with the user's sound signal, then synthesize it with the user's sound signal, and encode the synthesized signal into a format that can be broadcast to obtain a first broadcast signal. Here, the synthesized signal may be encoded by LC3 (Low Complexity Communication Codec).

[0064] In this embodiment, by synthesizing the collected user's voice signal with other voice signals in the wireless headset and then broadcasting them, it is possible to enrich the explanation function of the headset and improve the vividness and interactivity of the explanation.

[0065] In an exemplary embodiment, Figure 4 As shown, the above step S206 may include:

[0066] Step S2061, receiving the target transmit power sent by the terminal; the target transmit power is positively correlated with the number of target users.

[0067] Step S2062: broadcast the first broadcast signal according to the target transmission power.

[0068] Among them, the number of target users can be the number of users within a certain distance range. Exemplarily, the user who is giving the explanation can select the target transmission power of the strong / medium / weak transmission gear through the application in the terminal according to the size of the flow of people in the scene, and the application can set the transmission power of the wireless headset 110 to the target transmission power through the Bluetooth connection. When the wireless headset 110 is restarted, it can broadcast according to the current transmission power. When the number of target users is large, or the current flow of people is large, and the distribution of broadcast signal receivers is relatively scattered, the target transmission power can be increased so that people who are farther away can also receive clearer broadcast signals. When the number of target users is small, or the current flow of people is small, and the distribution of broadcast signal receivers is relatively dense, the target transmission power can be reduced to reduce the power consumption of the wireless headset 110.

[0069] In this embodiment, by dynamically adjusting the transmission power according to the actual number of listeners, it is possible to improve the battery life of the wireless headset while ensuring that the broadcast signal can effectively cover the required area.

[0070] In an exemplary embodiment, Figure 5 As shown, the above step S206 may include:

[0071] Step S2063, split the first broadcast signal to obtain multiple first broadcast signals.

[0072] Step S2064: Transmit one of the multiple first broadcast signals to the signal transmitting component of the wireless headset for broadcasting, and transmit another first broadcast signal to the sound output component of the wireless headset for playing.

[0073] The signal transmitting component may be a Bluetooth chip with a Bluetooth transmitting function. The sound output component may be a speaker. Exemplarily, when the user is giving a lecture, the first broadcast signal may be transmitted to the signal transmitting component of the wireless headset for broadcasting. At this time, if the user is in a noisy environment, the fourth target function may be turned on. In response to detecting the activation operation for the fourth function, the wireless headset 110 may split the first broadcast signal and transmit one path of the first broadcast signal to the sound output component of the wireless headset for playback.

[0074] In this embodiment, the explanation sound collected by the wireless headset is transmitted back to its own sound output component for playback, so that the user can clearly understand the effect of his own explanation and adjust his own voice and broadcast effect in time.

[0075] In an exemplary embodiment, Figure 6As shown, the above step S208 may include:

[0076] Step S2081: In response to detecting a start operation on a second target function, receiving a second broadcast signal.

[0077] Step S2082: When there are multiple second broadcast signals, in response to detecting a target switching instruction, another second broadcast signal different from the current second broadcast signal is selected from the multiple second broadcast signals for playback.

[0078] Among them, the target switching instruction may include but is not limited to a touch operation, a voice instruction, and an instruction sent by the terminal. Exemplarily, the wireless headset 110 can actively scan the Bluetooth broadcast in response to detecting the activation operation of the second target function. When there are multiple people broadcasting explanation information, or there are other broadcast signals in the broadcast frequency band, the wireless headset 110 can capture multiple second broadcast signals and store them in the broadcast signal list. The user can switch the broadcast signal in the playlist through the target switching instruction so that the user can receive the explanation information of interest.

[0079] Furthermore, the above-mentioned target switching instruction may include identification information of the target broadcast signal sent by the terminal, which can be used by the terminal to display description information of multiple second broadcast signals, and in response to detecting a selection operation of the target broadcast signal among multiple second broadcast signals, send the identification information of the target broadcast signal to the wireless headset.

[0080] Specifically, the application in the terminal may provide a user interface design (UI) for displaying the description information of multiple second broadcast signals. When the wireless headset 110 captures multiple second broadcast signals, the terminal may display the description information such as the broadcast name, broadcast number, channel, etc. of the multiple second broadcast signals on the UI of the application for the user to select. The wireless headset 110 may switch from the current second broadcast signal to the input path of the target broadcast signal input to the broadcast signal according to the identification information of the received target broadcast signal.

[0081] Optionally, when the wireless headset broadcasts a broadcast signal, a password can be set for the broadcast signal. When the user enters the corresponding password on the application UI and feeds back the correct password result to other wireless headsets that receive the broadcast signal, the other wireless headsets can play the broadcast signal.

[0082] In this embodiment, by integrating a response mechanism for broadcast signal switching in the wireless headset, the user can quickly and conveniently switch between different broadcast contents. Furthermore, by displaying playable broadcast signals on an intuitive terminal interface, the user can quickly find and select a broadcast signal of interest from among numerous broadcast signals, further improving the convenience of obtaining explanation information.

[0083] To summarize, by integrating the functions of explanation and reception in wireless headphones, when it is detected that the explanation function (first target function) is turned on, the user's voice will be collected in real time and processed and then broadcast, so that the explanation information can be transmitted to one or more wireless headphones with a receiving function in a broadcast manner. When it is detected that the receiving function (second target function) is turned on, the received broadcast is played, so that the explanation information can be obtained in a timely and convenient manner. It is suitable for explanation scenarios with multiple participants and participants can flexibly switch between the roles of explainer and receiver.
