Abstract: A method of reproducing audio sound using low level electromagnetism applied to ambient air particles to create a new magnetic field. The method uses a device having at least one winding of electric wires that re wound onto a flexible polymer support. The impedance of the winding is 8 Ohms. The device is connected to an electric audio signal of an acoustic chamber or an acoustic supply. The device and method are useable with audio and audio-video systems, as well as other known methods of communication.

Abstract: The creation of sounds by musical instruments or sound reproduction systems is not perfect, but acoustic dissonances inherent in the production of sound generators can be corrected. The present method uses open volumes, such as a glass, possibly provided with a cutoff, a fragmentation creating at least one opening. This object placed close to or on a sound generator frees additional sound waves to harmonise with the sound generator by means of mechanical coupling or an air sound link due to the volume of the resonator and its fragmentation. A device made of a material with a Shore hardness of more than 60 makes it possible via its foot fixed to a piano to transmit mechanical sound vibrations. Method and device constitute an effective improvement in the reproduction and creation of sounds.

Abstract: For musical instruments or sound reproduction, finer sound definition is preferable. In sound reproduction, electro-acoustic transducers fitted with round membranes or electrostatic system stripes are common. No system states that the sound created is correct for the human ear. The present method concerns a fractal shape responding to criteria of the human ear shape. A membrane which, like the ear via its shape, is a set of resonators with different frequencies. The membrane shape, known as a harmony amplifier, has independent tongues emitting from a given surface, like fingers of a hand coming out of the palm. A membrane can be put into digital form by tongues. The membrane is placed in a musical instrument. Another variant is a membrane mounted on a sound frequency generator constituting an electro-acoustic transducer. This is effective for all types of musical instruments and particularly for audio and audio-visual applications.
