Automobile key switch sound design method

Abstract

The invention discloses an automobile key switch sound design method, which comprises the following steps: determining a switch sound quality perception dimension with relatively high subjective scoring stability to form a switch sound subjective evaluation scale final edition, cutting a switch sound sample, and carrying out psychoacoustics objective parameter analysis to select an objective evaluation parameter initial edition; evaluating the switch sound sample according to the switch sound quality perception dimension, and selecting a switch sound design reference sample; quantifying objective evaluation parameters of the reference sample under the corresponding switch sound quality perception dimension, and performing correlation analysis and correlation credibility judgment on the preliminary objective quantification parameters and subjective evaluation scores of the corresponding switch sound quality perception dimension to obtain a final switch sound design psychological acoustics objective evaluation parameter edition; and determining subjective evaluation and objective evaluation parameter requirements of the switch sound design. According to the invention, the automobileswitch sound is designed by establishing a subjective and objective evaluation parameter design target system of the automobile switch sound, and the development of the automobile key switch sound quality is realized.

Description

Technical field[0001]The invention belongs to the technical field of automobile parts design and development, and specifically relates to a method for designing automobile key switch sound.Background technique[0002]Automobile key switches are important auto parts that control the working status of some parts of the vehicle. Their performance will directly affect the driving experience of the people in the car. Among them, the car key switches mainly include: key switches on the dashboard, and auxiliary dashboard The upper button switch, the button switch on the steering wheel and the button switch on the door trim panel.[0003]In the prior art, the design of automotive switches by technicians is embodied in the form of the switch, the structure of the switch or the shape of the switch. For example, for the inconvenience of operating the switch during night driving, a silicone button is designed to replace the traditional metal return spring. In order to solve the problem of difficult...
