ABSTRACT

The main purpose of this paper is developed the membrane, produced exciter, selected surround, optimal design method to manufacture gamut planar loudspeakers. Used nano-carbon tubes and foam board to combine the sandwich membranes which are applied the large planar loudspeakers. The optimal sandwich membranes which are including the stiffed pattern, minimum weight and stiffness are affected high frequency sound quality and sound pressure curve. Because of the sandwich membranes such as high stiffness and strong, and has received much attention as a new material for industrial applications. This creation of flat-panel speakers has the properties of light weight, thin exciter, and broad response of frequency, and also has the live sound quality and clear. The optimal programs are used finite element analysis and Fortran software to search optimal design parameters which are optimal sound quality and smooth curve of sound pressure at the 20Hz ~ 20KHz. Therefore, the optimal manufacturing parameters are manufactured sandwich planar loudspeakers which are measured experimental sound pressure curves to compare theory values.
