Abstract

In this paper, a method is presented to study the sound radiation of laminated composite plates subjected to transient vibration. A finite element model is constructed to model the laminated composite plate-type sound radiator of a flat-panel speaker. The response of the laminated composite plate subjected to transient vibration is obtained in a finite element analysis. The response of the plate is then used in the first Rayleigh integral to calculate the sound pressure produced by the plate. Different types of impulses are used to excite the plate to study the capability of the plate to produce sounds of high fidelity. The effects of lamination arrangement, material constants, and damping on the sound radiation capability of the plate are investigated by means of a number of examples. The results obtained in this paper will be useful for the audio engineers to design better composite flat-panel speakers.
