Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The sound effect experience of the real vehicle is more and more concerned and designed by the vehicle factory, and the quality of the sound effect experience of the real vehicle is continuously improved through software and hardware design. However, the design debugging and evaluation work of the real vehicle sound effect is mainly performed between a vehicle factory and a multimedia manufacturer, a terminal vehicle user can hardly participate in the design evaluation, and the final sound effect design result can not completely meet the different listening requirements of the user and can not meet the requirement of the user on the real vehicle environment for performing later effective optimization design.

Referring to fig. 1 and fig. 2, to achieve the above object, the system for designing and debugging sound effects of an actual vehicle provided by the present embodiment includes a client and a server.

Wherein

The client provides an interactive window and is pre-installed with a sound effect debugging application program;

and the server side provides a data debugging interface and receives and responds the sound effect debugging data transmitted by the client side.

The system architecture is built based on a Client/Server structure, and the vehicle-mounted multimedia is used as a Server end and provides a data debugging interface; and an application program of the mobile phone end serves as a client to provide an interactive window for a user, and the mobile phone and the vehicle-mounted multimedia are connected with interactive sound effect debugging data through a common mobile phone data line.

Specifically, the vehicle-mounted multimedia serves as a server end and comprises a CPU, an audio processor DSP and an audio power amplifier which are sequentially connected, and further comprises a USB port which is bidirectionally connected with the CPU and is unidirectionally connected with the audio processor DSP.

The USB port of the vehicle-mounted multimedia is communicated with the client through a data line. The USB interface of the vehicle-mounted multimedia host is used as a debugging interface, so that the defect that a user vehicle needs to be disassembled to connect a special debugging interface inside the audio host is overcome.

According to a specified vehicle-mounted multimedia communication protocol, a sound effect debugging application program of a mobile phone end is utilized to carry out real-time communication with a sound host CPU, the CPU is used as a vehicle-mounted multimedia server end to interactively transmit corresponding sound effect debugging data, and the sound host CPU and an audio processor DSP carry out debugging and writing-in of real-time sound effects through an integrated circuit built-in audio bus I2S, so that adjustment of DSP sound effect parameters is realized.

The audio processor DSP is also connected with a BT/MCU. The CPU and the audio processor DSP are connected through an audio bus I2S. Other audio media input ports of the vehicle-mounted multimedia such as BT and BT music transmit audio data to an MCU (microprogrammed control unit) through a UART (universal asynchronous receiver/transmitter) communication protocol, the MCU manages sound source signals, the audio data are transmitted to an audio processor DSP (digital signal processor) through an integrated circuit built-in audio bus I2S, and the DSP converts the audio data into analog audio signals or directly transmits the digital audio signals through a digital-analog converter according to the type of power amplification and then outputs the analog audio signals to a vehicle body loudspeaker through the amplification of a rear-stage audio power amplifier; therefore, the effect of the sound effect debugging parameters is evaluated in real time.

The vehicle-mounted sound effect debugging is mainly carried out on a preceding stage audio processor DSP of a power amplifier, and corresponding key sound effect parameters such as time delay, distortion, filtering, gain, bandwidth, frequency response and the like can be debugged in real time through the setting of sound effect debugging application software of a mobile phone; after the sound effect parameters take effect, the sound effect parameters can be embodied on the currently played BT music in real time, and the unsatisfactory sound effect can be debugged and improved in time so as to meet the user-defined sound effect requirement.

The real vehicle sound effect debugging application program at the mobile phone end can set the personal height, weight, listening hobby and other information of the user so as to quickly locate the parameter demand value of sound effect debugging of the user. The application program can be suitable for installation of Android and iOS systems.

According to the method and the device, the sound effect debugging application program of the mobile phone can realize that the vehicle terminal user debugs the vehicle sound effect parameters in real time according to the individual listening requirement, so that the user experience of the product is improved, and the competitiveness of the product in the market is improved.

The above-described embodiments do not limit the scope of the present invention. Any modification, equivalent replacement, and improvement made within the spirit and principle of the above-described embodiments should be included in the protection scope of the technical solution.
