Development High Stiffness Ratio of Stiffened Membranes for Small Flat Speakers

Abstract:

This research for the membrane stiffening manufacture, thickness, weight, manufacturing parameters, stiffness and surface uniformity was discussed. The used of hand rough paper as membrane substrate, and used of roller coating, spray coating of coating methods, and it carried on membrane stiffening process of carbon nanotubes. On the increase smallest weight, it had been a large increase in stiffness, and the flat speakers sound pressure curve smoother. Used different proportion of carbon nanotubes mixture of different resin to membrane stiffening, used SEM to detect the carbon nanotubes stiffening of the membrane surface coating uniformity, even different coating of compare thickness with weight of increase percentage. It used tensile test to explore different coating methods of Young's modulus of the difference. Then, we was manufactured the small plane speaker (L33mm×W21mm×H12mm) according to the various membrane stiffening and measure the sound pressure curve, and it contrasted with computer-aided analysis software obtained the theory of sound pressure curves.
