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.
