Definitions
- a product such as the plasma enclosure was close to the physical performance of air since it acted on the level of air particles.
- the disadvantage of this process was a chemical transformation of the air composition and for this the means of implementation were relatively expensive.
- the present method is a complement to the current sound reproduction systems such as the loudspeakers used. These speakers create the necessary sound bases but without any refinement, and in particular have a characteristic defect which is the non respect of the sound intermodulation.
- the present method and apparatus superimposes the coarse sound signal of the loudspeakers, the fine sound information contained in the original audio electric signal. This sound information is the amplification and the precise order of the harmonics in space-time.
- the present method uses low level electromagnetism which is based on the particles of the ambient air thus creating a new magnetic field on the terrestrial magnetic field. So the air particles are agitated by the new variable magnetic field in opposition to the stable reference earth magnetic field.
- the new magnetic field is defined by the single use of at least one excited solenoid, activated by the electrical audio sound signal, of an acoustic amplifier.
- the present process amplifies the sound harmonics of low level but of great importance for the auditory perception and thus allow a very clear reproduction of the sound.
- the speed of sound execution of this process is characterized by the absence of inertia and mechanical drag as executed by the solenoid, with no apparent mechanical movement.
- the sound emission is thus produced by the agitation of the molecules in space on the one hand and can, on the other hand, depending on the types or modes of windings, be produced by the sound micro-vibrations of the electrical wires of the or solenoids.
- a variant of the method is a solenoid with at least one magnet inside or outside, which activates its effect but reduces its sensitivity due to the remanence of the magnetic field of the magnet which imposes its constant of magnetic field, masking the earth's magnetic field.
- This process is characterized by an apparatus consisting (Fig 1) of at least one winding of electric wires (1) in this case, 1/10 of a millimeter wound on a flexible support (2) made of polymer 10 cm long and 0.8 cm in diameter.
- the impedance of this winding is 8 Ohms, the winding is characterized in that each layer (3, 4) is wound in the same winding direction, the return wire (5) being placed along the winding.
- This winding mode allows micro-vibrations between the turns, given the voltage difference between the turns of the first and second layer. These micro-vibratio ⁇ s involved in the amplification of sound harmonics.
- This device is coupled to an audio electrical signal from a acoustic enclosure or acoustic power supply. This device complements the usual electro-acoustic transducers. This device is produced by a person skilled in the art and represents a non-limiting example of carrying out this process.
- This device (Fig 1) is integrated (Fig 2) in an acoustic enclosure (8) in front of the facade (1).
- the electro-acoustic transducer solenoid (2) of this device is mounted free in the ambient air next to the Tweeter (3).
- This new electro-acoustic transducer could be mounted directly on the general audio power supply between the amplifier and the acoustic enclosure. These new electro-acoustic transducers can be mounted together in series or in parallel or both. These acoustic transducers are harmonic amplifiers.
- the present electro-acoustic method and apparatus limited to a winding of electric wire without a membrane gives an unequaled acoustic finesse.
- Several windings one on the other also constitute an electro-acoustic transducer of the same kind as that presented in the present process, of a more complex embodiment.
- This device and method can be used on all audio systems, audiovideo and any mode of communication such as telephones, radio, as well as by the medical world for improving the hearing comfort of the hearing impaired.
