COMSOL software-based loudspeaker frequency curve analysis method and device

Abstract

The invention discloses a COMSOL software-based loudspeaker frequency curve analysis method and device. The method comprises the following steps of: establishing a 2D or 3D loudspeaker simulation model and endowing the loudspeaker simulation model with material characteristics; carrying out finite element analysis on the loudspeaker simulation model; judging whether a frequency response curve of the loudspeaker simulation model accords with a design requirement or not; if the judging result is positive, taking structure parameters and material parameters as design parameters of a loudspeaker; and if the judging result is negative, adjusting the structure parameters and the material parameters until the frequency response curve accords with the design requirement. According to the method and device disclosed by the invention, acoustic-structure coupling analysis is carried out on the loudspeaker simulation model on the basis of COMSOL software, so that peak values and valley points on the loudspeaker frequency response curve can be decreased, thereby improving the tone quality and performance, avoiding the problem that the tone quality and parameters of the loudspeaker are unqualified as the loudspeaker is designed according to rules of thumb, improving the production efficiency and decreasing the production cost.

Description

technical field [0001] The invention relates to the technical field of loudspeakers, in particular to a method and device for analyzing frequency curves of loudspeakers based on COMSOL software. Background technique [0002] In modern society, cars have become an indispensable tool in people's lives. Private cars and buses facilitate people's travel. Cars are replacing bicycles as an important means of transportation in people's lives. In recent years, with the continuous improvement of people's requirements for automobiles, especially the increasing requirements for various personalized enjoyment in the car, major car manufacturers in the world have paid more and more attention to the sound-generating parts of the speakers in the car. joyful. For major speaker manufacturers, improving performance is very important, and the frequency response curve is an important indicator for judging the overall sound quality of speakers. How to optimize the frequency response curves of d...

Problems solved by technology

At present, the traditional method of developing loudspeakers is always to make molds for each component based on past experience, and then assemble samples for testing. If the frequency response curve does not meet the requirements, especially in terms of early development costs and time planning, it will be disadvantageous. influences
