The embodiments described below by reference to the accompanying drawings are exemplary and are intended to explain the present application, and cannot be understood as limiting the present application.

[0026] The entertainment system, method, vehicle and storage medium of a vehicle according to an embodiment of the present application are described below with reference to the accompanying drawings. In the related art mentioned in the above background section, the use of the vehicle microphone is limited by hardware and physical location, which has poor effects in sound pickup, noise reduction, etc., high data transmission delay, and the same voice channel is shared with the interactive system, which requires additional processing on the system side.

Thus, the technical problems of the related art, such as the use of the vehicle microphone being limited by hardware and physical location, poor effects in sound pickup, noise reduction, etc., high data transmission delay, and the same voice channel being shared with the interactive system, which requires additional processing on the system side, are solved.

[0027] Specifically, Figure 1 A structural diagram of an entertainment system for a vehicle according to an embodiment of the present application is provided.

[0028] As Figure 1 shown, the entertainment system 10 for a vehicle includes at least one microphone 100, a signal processing module 200 and an application layer module 300.

[0029] Specifically, the at least one microphone 100 is built into the vehicle to capture human voice audio data of people in the vehicle.

[0030] In actual implementation, when the entertainment function, such as the singing function, is enabled, the embodiment of the application can capture the voice of the person in the vehicle through at least one microphone 100 built in the vehicle, so as to obtain the voice data of the person in the vehicle, without external equipment, thereby reducing the cost.

[0031] The signal processing module 200 is configured to pre-process the voice data of the person to obtain dry voice data.

[0032] In some embodiments, the captured voice data of the person can be transmitted to the signal processing module 200, so as to pre-process the voice data of the person through the signal processing module 200 to realize voice enhancement and noise reduction, thereby obtaining the dry voice data.

[0033] Optionally, in an embodiment of the application, the signal processing module 200 comprises a preprocessing unit configured to perform noise reduction processing on the voice data of the person while eliminating the echo in the voice data of the person.

[0034] It can be understood that the vehicle microphone is generally a far-field microphone, which is omnidirectional and suitable for voice interaction, and has poor effects in sound pickup, noise reduction, etc. Many environmental noises can be collected, and the effects of anti-howling and echo elimination are affected by the physical position of the hardware, which is difficult to solve. Therefore, the embodiment of the application can pre-process the voice data of the person through the signal processing module 200, obtain pure voice dry sound through echo elimination and noise reduction processing, and further generate voice dry sound data.

[0035] The application layer module 300 has an audio HAL interface, which is configured to use a preset reverberation algorithm to perform reverberation on the dry voice data to generate wet voice data, and send the wet voice data and the accompaniment audio data to the signal processing module 200 through the audio HAL interface, so that the signal processing module 200 mixes the wet voice data and the accompaniment audio data to generate entertainment audio data.

[0036] As a possible implementation manner, taking the Android side application layer as an example, the application layer module 300 of the embodiment of the application can comprise an ear return application, a singing application, etc. The ear return application can directly obtain the voice dry sound data through the audio HAL interface, which greatly shortens the time delay caused by the uplink transmission and processing of the audio stream. The singing application can directly obtain the voice dry sound data from the interface of the ear return application to realize the corresponding business logic, such as scoring, recording, etc., by using the voice dry sound data.

[0037] Further, the embodiment of the present application can send the corresponding accompaniment audio data to the earphone application through the singing application, and utilize a preset reverb algorithm in the earphone application to realize the reverb effect of the vocal dry sound and generate vocal wet audio data. The preset reverb algorithm can be set by a person skilled in the art based on the actual situation, and is not specifically limited herein.

[0038] The earphone application can call the audio HAL interface to send the accompaniment audio data and the wet audio data to the signal processing module 200 for mixing, thereby greatly shortening the time delay caused by transmission and processing when the audio stream is downlink to the driver.

[0039] Optionally, in an embodiment of the present application, the entertainment system 10 of the vehicle further comprises an interaction module and a control module.

[0040] The interaction module is configured to receive the entertainment interaction instruction of the user and generate a corresponding entertainment signal based on the entertainment interaction instruction.

[0041] The control module is configured to start at least one microphone 100 based on the entertainment signal, and control the application layer module 300 to generate corresponding accompaniment audio data.

[0042] In actual execution process, the embodiment of the present application can obtain the entertainment interaction instruction of the user, including the entertainment function selection, the song selection, etc., through the interaction module, such as the vehicle central control screen interaction and the mobile terminal interaction bound with the vehicle, and generate the corresponding entertainment signal based on the entertainment interaction instruction.

[0043] The embodiment of the present application can control at least one microphone 100 to start based on the entertainment signal through the control module, so as to capture the vocal audio data, and control the application layer module 300 to generate the accompaniment audio data corresponding to the entertainment interaction instruction.

[0044] Optionally, in an embodiment of the present application, the application layer module 300 comprises a matching unit.

[0045] The matching unit is configured to retrieve the preset accompaniment database with the entertainment signal as an index to obtain the accompaniment audio data.

[0046] In some embodiments, the application layer module 300 can comprise the matching unit. The embodiment of the present application can determine the accompaniment instruction of the user in the entertainment interaction instruction based on the entertainment signal through the matching unit, retrieve the corresponding accompaniment in the preset accompaniment database, match to obtain the accompaniment data, so as to be mixed with the wet audio data.

[0047] Optionally, in an embodiment of the present application, the entertainment system 10 of the vehicle further comprises a power amplifier module.

[0048] The power amplifier module is used to control at least one audio playback device in the vehicle to play entertainment audio data.

[0049] As one possible implementation, embodiments of this application can use a power amplifier module to control at least one audio playback device in the vehicle, such as a car speaker, to play entertainment audio data mixed and generated by the signal processing module 200, thus completing the entertainment singing process. Combined with... Figure 2 and Figure 3 As shown, the working principle of the vehicle entertainment system 10 of this application embodiment will be described in detail with reference to one embodiment.

[0050] like Figure 2 As shown, embodiments of this application may include at least one microphone 100, a signal processing module 200, an application layer module 300, and a power amplifier module 400.

[0051] The signal processing module 200 is taken as the DSP (Digital Signal Processor) built into the DMC host SOC (System on Chip). The SOC is a multi-operating system (QNX+Android) software environment based on a virtual machine. The application layer module 300 can include singing applications, earphone monitoring applications, etc. The singing application and vocal reverb can be deployed in the Android system. The sound noise reduction and vocal reverb are processed by software modules and deployed in the DSP coprocessor, i.e., the signal processing module 200.

[0052] In practical applications, when singing, the human voice is captured by the vehicle microphone 100. The human voice audio stream is sent to the signal processing module 200, where echo cancellation and noise reduction are performed to obtain a pure human voice.

[0053] The human voice audio stream is sent to the Linux kernel audio subsystem of the Android side of the application layer module 300. The singing application of the application layer module 300 bypasses the audio subsystem of the Android Framework layer and directly calls the audio HAL interface to obtain the human voice audio data stream, so that the time delay caused by the transmission and processing of the audio stream in the Android Framework when the audio stream is transmitted to the application layer is greatly shortened. The singing application can use the obtained human voice audio stream to implement corresponding business logic, such as scoring, recording, and the like. The ear return application mixes the human voice to obtain a wet voice audio data stream. The singing application sends the accompaniment audio stream of the song to the signal processing module 200 by calling the audio HAL interface of the ear return application. This operation also bypasses the audio subsystem in the Android, and greatly shortens the time delay caused by the transmission and processing of the audio stream in the Android Framework when the audio stream is transmitted to the driver. After the human voice audio stream is mixed in the signal processing module 200, the human voice audio stream is transmitted to the power amplifier through a digital audio interface such as TDM (time-division multiplexing) and is played by the power amplifier module 400.

[0054] As shown in Figure 3 the embodiments of the present application can include the following steps:

[0055] Step S1: capturing human voice audio data by at least one microphone 100 and transmitting the human voice audio data to the signal processing module 200.

[0056] Step S2: performing echo cancellation and noise reduction processing in the signal processing module 200 to obtain pure human voice dry audio data.

[0057] Step S3: transmitting the dry audio data to the Linux kernel audio subsystem of the Android side of the application layer module 300.

[0058] Step S4: the ear return application of the application layer module 300 bypasses the audio subsystem of the Android Framework layer and directly calls the audio HAL interface to obtain the dry audio data, so that the time delay caused by the transmission and processing of the audio stream in the Android Framework when the audio stream is transmitted to the application layer is greatly shortened.

[0059] Step S5: the singing application can directly obtain the dry audio data from the interface of the ear return application, and use the obtained human voice audio stream to implement corresponding business logic, such as scoring, recording, and the like.

[0060] Step S6: the singing application simultaneously and in real time sends the accompaniment audio stream of the singing song to the ear return application, and uses a reverberation algorithm in the ear return application to implement the reverberation effect of the human voice dry sound to obtain wet audio data.

[0061] Step S7: The ear return application calls the audio HAL interface to send the accompaniment audio data and the wet audio data of the song to the signal processing module 200 for mixing. This operation also bypasses the audio subsystem in Android, greatly shortening the time delay caused by transmission and processing in the Android Framework when the audio stream is sent down to the driver.

[0062] Step S8: After the wet audio data and the accompaniment audio data are mixed and processed in the signal processing module 200, they are transmitted to the power amplifier module 400 through a digital audio interface such as TDM, and are driven by the power amplifier module 400 to play through the car speakers.

[0063] The entertainment system of the vehicle according to the embodiments of the present application can reduce costs by using the built-in microphone, preprocess the human voice audio data of the people in the vehicle captured by the built-in microphone, perform human voice enhancement and noise reduction to obtain dry audio data, use a preset reverberation algorithm to perform reverberation on the dry audio data to obtain wet audio data, mix the wet audio data and accompaniment audio data to generate entertainment audio data, and implement the use of the in-vehicle entertainment function. The dry audio data, the wet audio data, and the entertainment audio data can all be transmitted through the audio HAL interface, which can reduce data transmission delay and improve user experience. Thus, the technical problems in the related art that the use of the vehicle microphone is limited by hardware and physical location, the sound pickup and noise reduction are not good, the data transmission delay is high, the same voice channel is shared with the interactive system, and additional system processing is required are solved.

[0064] Next, the entertainment method of the vehicle according to the embodiments of the present application is described with reference to the accompanying drawings.

[0065] Figure 4 is a flowchart of the entertainment method of the vehicle according to the embodiments of the present application.

[0066] As shown in Figure 4 , the entertainment method of the vehicle includes the following steps.

[0067] In step S401, human voice audio data of people in the vehicle is captured.

[0068] In step S402, the human voice audio data is preprocessed to obtain dry audio data.

[0069] In step S403, a preset reverberation algorithm is used to perform reverberation on the dry audio data to generate wet audio data, and the wet audio data and accompaniment audio data are mixed to generate entertainment audio data.

[0070] Optionally, in an embodiment of the present application, preprocessing the human voice audio data includes eliminating echo in the human voice audio data and performing noise reduction processing on the human voice audio data.

Therefore, the technical problems in the related art that the use of the vehicle microphone is limited by hardware and physical position, the sound pickup, noise reduction and other aspects are not good, the data transmission delay is high, the same voice channel is shared with the interaction system, and additional processing is required on the system side are solved.
