Abstract: The present invention relates to nanocomposite materials based on a copolymer of at least two monomers selected from the group consisting of butadiene, isoprene and styrene and a clay mineral dispersed therein, and a process for preparing them. By using an organolithium as the initiator, an organic hydrocarbon solvent as the solvent and a polar additive as the microstructure modifier by means of a classical anionic solution polymerization process, at least two monomers selected from the group consisting of butadiene, isoprene and styrene are in-situ intercalation polymerized in the presence of an organoclay, thereby obtaining a delaminated nanocomposite material which is excellent in mechanical properties, heat resistance, barrier property, chemical resistance and is well balanced in its comprehensive properties.

Abstract: This invention is a loudspeaker that consists of some vibratory membranes and magnets. Every vibratory membrane is a part of a soft conductive tape and is put in a magnetic field. When the membranes conduct audio current, they vibrate air directly with their surfaces, and produce sound waves. This loudspeaker can be made into various shapes. It has overcome the defect of sound distortion caused by the diaphragm deformations in regular loudspeakers. Its distortion is lower, its transient response is excellent, and its voice quality and acoustic effects are admirable.
