[0026] The embodiments of the present invention will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention and not for limiting the scope of protection of the present invention.

[0027] This application provides an in-vehicle system for playing panoramic sound sources. Figure 1 A block diagram of an in-vehicle system for playing panoramic sound sources, such as... Figure 1 As shown, the in-vehicle system includes: a personal computer, an audio processing system, an audio amplifier module, and an audio playback system. The input of the audio processing system is connected to the personal computer, and the output of the audio processing system is connected to the audio amplifier module. The output of the audio amplifier module is connected not only to the audio playback system but also to the input of the audio processing system, enabling the audio processing system to perform sound compensation on the amplifier's processed audio data.

[0028] A personal computer, or PC, uses USB transmission to send panoramic sound source control commands and initial audio data to the audio processing system. The audio processing system analyzes the panoramic sound source control commands and initial audio data, then sends them to the audio amplifier system. The audio amplifier system amplifies the initial audio data according to the panoramic sound source control commands, obtaining amplifier audio data, which is then sent to the audio playback system for playback. The vehicle is also equipped with sound sensors that collect audio playback data and send it to the audio processing system. The audio processing system determines whether the audio playback effect meets the preset effect based on the audio playback data. If it does, no further processing is performed; otherwise, if the preset effect is not met, sound compensation is applied to the amplifier audio data to achieve the preset audio playback effect.

[0029] In this application, the initial audio data, after being processed by the audio processing system and amplified by the power amplifier audio module, becomes power amplifier audio data. If the audio playback effect of the power amplifier audio data does not meet the preset effect, sound compensation is performed on the power amplifier audio data to achieve the preset effect. This application improves the audio playback effect of the panoramic sound source's audio data by achieving the preset effect through sound compensation.

[0030] Optionally, the audio processing system includes a high-speed digital signal processor and a digital audio processor. The input terminal of the high-speed digital signal processor is connected to the personal computer, the output terminal of the high-speed digital signal processor is connected to the input terminal of the audio power amplifier module, and the input terminal of the digital audio processor is connected to both the output terminal of the high-speed digital signal processor and the input terminal of the audio power amplifier module.

[0031] The personal computer uses USB transmission to send panoramic sound source control commands and initial audio data to a high-speed digital signal processor (DSP). The DSP performs logical judgments on the panoramic sound source control commands and transmits them to the audio amplifier module. The DSP and the digital audio processor (DAP) interact via SPI communication. The DSP sends the initial audio data to the DAP, which analyzes the data, including sound source encoding, synthesis, and decoding, before sending the analyzed data to the audio amplifier module. The audio amplifier module then amplifies the analyzed initial audio data and prepares it for playback.

[0032] Specifically, the output of the audio amplifier module is connected to the input of the digital audio processor. The audio amplifier module sends the processed audio data to the digital audio processor in I2C data transmission format. After the audio playback system plays the audio data, the sound sensor acquires the audio playback data output by the audio playback system and sends the audio playback data to the high-speed digital signal processor. Then, the high-speed digital signal processor compensates for the audio playback effect according to the preset loudness and preset gain. Specifically, if the loudness of the audio playback data does not reach the preset loudness, loudness compensation is performed on the audio playback data; if the loudness of the audio playback data does not reach the preset gain, gain compensation is performed on the audio playback data.

[0033] High-speed digital signal processors can not only determine sound compensation based on audio playback data, but also determine the adjusted position of the external player, thereby making the placement of the external player more reasonable and achieving bright highs, clear mids, and good bass texture and quantity. Figure 2This diagram illustrates the placement of external media players, showing that different speakers are positioned in different locations. Figure 2 In the center, the circled parts from left to right are: tweeter, door midrange speaker, and woofer.

[0034] Optionally, the digital audio processor includes: an audio processing module, an audio encoding module, and an audio decoding module. The input terminal of the audio processing module is connected to the output terminal of the high-speed digital signal processor and the output terminal of the audio power amplifier module, respectively. The input terminal of the audio encoding module is connected to the output terminal of the audio processing module, and the input terminal of the audio decoding module is connected to the output terminal of the audio encoding module and the input terminal of the audio power amplifier module.

[0035] The high-speed digital signal processor (DSP) sends initial audio data to the audio processing module via the SPI communication protocol. After analyzing the initial audio data, the audio processing module sends it to the audio encoding module, which encodes the initial audio data. The encoded initial audio data is then sent to the audio decoding module, which decodes the encoded initial audio data. The transmission of audio data between the various processing hardware components is achieved through the data transmission module.

[0036] In addition, the audio amplifier module sends the amplifier audio data to the audio processing module. The audio processing module performs sound compensation on the amplifier audio data based on the sound compensation information, and then encodes it through the audio encoding module and decodes it through the audio decoding module before inputting it back to the audio amplifier module. The audio amplifier module amplifies the audio data and performs pre-playback preparation work. Finally, the audio playback system plays the sound-compensated amplifier audio data.

[0037] Optionally, the audio playback system includes: an audio playback module, an external player, and a 4D vibrator. The input terminals of the audio playback module, the external player, and the 4D vibrator are respectively connected to the output terminal of the audio amplifier module. The audio playback module, the external player, and the 4D vibrator jointly play panoramic sound sources.

[0038] Optionally, the system further includes a power module, which is connected to the personal computer, the audio processing system, the audio amplifier module, and the audio playback system. In addition to supplying power, the power module is also used to filter the initial audio data sent by the personal computer, so that the initial playback data used subsequently is filtered, which can make the voltage more stable.

[0039] Figure 3This is a schematic diagram of the hardware structure of the vehicle power amplifier system according to an embodiment of this application. The PMIC is used to power the ADSP-21565SHARC DSP (Digital Audio Processor) and MCU (High-Speed ​​Digital Signal Processor), and the BOOSTER is used to power the AMP (Audio Amplifier Module). It can be seen that the digital audio processor and the high-speed digital signal processor use the SPI communication protocol, the high-speed digital signal processor and the audio amplifier module use the I2C communication protocol, or the TMD communication protocol (not shown in the figure), and the digital audio processor and the audio amplifier module use the I2S and TDM communication protocols.

[0040] Figure 4 This is an architecture diagram of a digital audio processor used for frequency modulation in an audio system, according to an embodiment of this application. Analysis Figure 4 It is known that the panoramic sound source control command of the USB flash drive can use the system's upper-level chip SOC or MCU microprocessor to analyze and process the audio data. The processed audio data is transmitted to the digital audio processor through the SPI full-duplex bus communication protocol for further processing of the audio data. After processing, the signal is amplified and finally played through the external player and 4D oscillator.

[0041] Figure 5 This is a schematic diagram of an in-vehicle music external amplifier system according to an embodiment of this application. Figure 5 It can be seen that a proper configuration of the hardware, audio processing software, audio processing algorithms, and matching car amplifier hardware is necessary to ensure that the audio files play to the desired effect.

[0042] This application configures the vehicle amplifier hardware and software so that, during the data interaction process between the digital audio processor, high-speed digital signal processor, and audio amplifier module, the audio data is played back with the help of a third-party audio processing algorithm, and the external player achieves the preset playback effect, so that the vehicle audio system can deliver bright highs, clear mids, and good bass quality and quantity.

[0044] Step 601: The PC uses USB transmission to send the panoramic sound source control command and initial audio data to the high-speed digital signal processor.

[0045] Step 602: The high-speed digital signal processor sends the panoramic sound source control command to the audio power amplifier module through the TMD communication protocol, and sends the initial audio data to the digital audio processor using the SPI data format.

[0046] Step 603: The audio amplifier module amplifies the initial audio data and sends the amplified audio data to the digital audio processor via the I2C communication protocol. At the same time, the audio amplifier module sends the amplified audio data to the audio playback system.

[0047] Step 604: The sound sensor collects the audio playback data played by the audio playback system and sends the audio playback data to the high-speed digital signal processor.

[0048] Step 605: The high-speed digital signal processor determines the sound compensation information based on the audio playback data and sends the sound compensation information to the digital audio processor.

[0049] Step 606: The digital audio processor compensates the power amplifier audio data based on the sound compensation information.
