Device and method for debugging sound effect parameters of a vehicle entertainment system

Abstract

The invention provides an on-board entertainment system sound effect parameter debugging device and a debugging method. The debugging device comprises an on-board entertainment system module, a sound effect parameter debugging module, and a wireless communication module. The on-board entertainment system module and the sound effect parameter debugging module are connected with the wireless communication module, and the wireless communication between the on-board entertainment system module and the sound effect parameter debugging module can be realized by the wireless communication module. The sound effect parameter debugging module is used for the real-time modification of the sound effect parameters, and is used for the generating of the sound effect parameter debugging files. The sound effect parameters and the sound effect parameter debugging files can be transmitted to the on-board entertainment system module by the wireless communication module. The on-board entertainment system can be used to play the entertainment files according to the sound effect parameters, and can be used to store the sound effect parameter debugging files. By adopting the technical scheme provided by the invention, the own wireless communication module can be used for the sound effect parameter debugging, and the introducing of the wire harness is not required, and in addition, the sound effect parameter can be stored independently, and therefore the debugging device and the debugging method are compatible with different vehicle models.

Description

technical field [0001] The invention relates to the field of sound effect parameter debugging, in particular to a device and method for matching sound effect parameters of a vehicle entertainment system. Background technique [0002] With the development of automotive electronics technology, the car entertainment system has also become an important part of the car, and users have higher and higher requirements for the sound quality of the car entertainment system. Due to the particularity of the space inside the car, it is necessary to match the sound parameters of the real car in order to achieve the best sound quality. The existing matching of sound effect parameters usually has the following three processing methods: 1. Do not perform real vehicle parameter matching, only test and adjust objective parameters in the laboratory, and do not conduct field sound effects based on the actual vehicle model used by the entertainment system Parameter debugging, this will cause the...

The existing matching of sound effect parameters usually has the following three processing methods: 1. Do not perform real vehicle parameter matching, only test and adjust objective parameters in the laboratory, and do not conduct field sound effects based on the actual vehicle model used by the entertainment system Parameter debugging, this will cause the sound effect not to match the model, and the sound quality is poor; 2. Connect directly to the DSP inside the entertainment system through the IIC for debugging, such as figure 1 As shown, this method needs to solder the connecting wires from the entertainment system and connect them to the computer. The operation is complicated, and because the MCU and the computer may communicate with the DSP at the same time, it will cause communication conflicts and affect the correctness of parameter debugging; 3. Through UART Connect to the inside of the entertainment system for debugging, such as figure 2 As shown, the UART inside the entertainment system is connected to the connector of the external device, and then connected to the computer through the serial port, and the computer communicates with the MCU of the entertainment system. This method needs to occupy the harness interface of the connector, which will increase the cost and security issues

In addition, both the second and third methods above need to connect wiring harnesses, which is inconvenient for debugging. After debugging, the debugged data is usually integrated into the software code, and then solidified in the flash memory inside the system. It will cause the entertainment system to change the application scenario, and the software needs to be modified
