Abstract

The invention discloses a loudspeaker mesh cover design method based on a finite element method. The loudspeaker mesh cover is simulated and designed by the finite element method, and the loudspeakermesh cover shape can be optimized in the prophase of the design to adjust the loudspeaker performance, speed up the loudspeaker design and development progress, and reduce the development cost. A loudspeaker mesh cover design method based on finite element method comprises the following steps: S1, making a three-dimensional model of the loudspeaker with the mesh cover; 2, establishing a finite element model of that loudspeaker with a mesh cover accord to the three-dimensional model; S3, exciting the loudspeaker to the finite element model; S4, setting the parameters of the screen cover; S5, solving the finite element model by the control variable method and the parameterized scanning model, calculating the frequency response curves corresponding to the screen covers with different parameters, and comparing and selecting the optimal solution.

Description

technical field [0001] The invention relates to the field of loudspeakers, in particular to a method for designing loudspeaker grilles based on the finite element method. Background technique [0002] With the continuous improvement of people's living standards, music has become an indispensable part of people's lives. The sound quality and appearance of speakers have become the two focuses of the current market. At present, the general design scheme of loudspeaker grilles is to make samples, test, improve samples, and repeat the process. This kind of scheme has a long development cycle and high cost. Contents of the invention [0003] In view of the above problems, the present invention provides a method for designing speaker grilles based on the finite element method. The speaker grille is simulated and designed by the finite element method, which can optimize the shape of the grille in the early stage of design to adjust the performance of the speaker and speed up the ...
