Speaker calm piece shape design


The calm piece is in the electrodynamic loud speaker vibrating system an important part, usually uses the circle ring-like corrugated sheet together which the textile material makes. When its stress has the vibration often will have the non-linear deformation, this will cause the speaker to have the nonlinear distortion, will affect speaker's quality scale. Has carried on the survey to the actual calm piece, obtained the calm piece under different load displacement real value. Finally will simulate the value and the actual observed value has carried on the contrast, confirmed uses the finite element analysis the method to simulate the calm piece displacement load curve the feasibility and the validity. In confirmation simulation valid foundation, also the reason which produces to the calm piece non-linearity has carried on the brief analysis
