Composite laminates for generating an amplification effect by the drive and the drive for the composite laminate to a panel speaker formed by having an gyeokjin driving a result, the material for the composite laminate has a public address function is of particular fiber angle and the orthogonality with stacked by having a fiber-reinforced composite layer yirueojim, is formed on the edge strength of the periphery of the laminate and this portion is formed to each other biasing the strip, these biasing strip the laminate is uniformly distributed than the sound pressure sensitivity in a certain frequency range, It is to adjust the mode of vibration. On the other hand, and the high area of the laminate and dividing into two public address area of hyoneungwa low efficacy, fixed on a specific position pre-installed in the high efficiency amplification region of an above gyeokjin the laminate in order to improve the amplification efficiency of the composite laminate . On the periphery of the composite laminate it is connected to a hanging system for supporting the flexible composites of the laminate for the public address and, in the hanging system to remove the noise that is generated on the periphery of the public address by the tamper plate. ; Composites, laminates, remote oscillator, panels, speakers, public address
