Description
Harmonic amplifier and corresponding electro-acoustic transducer Field of the invention The invention relates to a device that improves an audio sound emitted by at least one acoustic baffle.
Background of the invention 1o In the field of sound reproduction, it is normal practice to use membranes excited by diamond motors or electrostatic strip systems.
It is normal to identify these products by acoustic efficiencies and acceleration speeds.
AII these products have significant masses in movements to produce the sound.
On the other hand, sound is an impact between air particles which have infinitely small masses conferring high sound propagation speeds, namely about 300 meters per second.
One product, such as the plasma chamber, was close to the physical performances of air since it acted on the level of the air particles. The drawback of this method was that it went through a chemical transformation of the composition of the air, and in order to do this, relatively expensive means were used.
Summary of the invention The present method is a complement to current sound reproduction systems, such as the acoustic chambers used. These chambers create the required sound bases but are not refined and in particular have a characteristic defect in that they do not observe sound intermodulation. The present method and device superimpose on the coarse sound signall of the chambers the fine sound information contained in the original electric audio signal. This sound information has the precise order and amplification of space-time harmonics.
The present method uses low level electro-magnetism which is applied to the ambient air particles, thus creating a new magnetic field on the terrestrial magnetic field. Thus, the air particles are agitated by the new magnetic field which varies in opposition to the stable reference terrestrial magnetic field.
Thus, the present method amplifies the Iow-level sound harmonics, but to a larger 1o extent for auditive perception and thus permit extremely clear sound reproduction. The speed of sound execution of this method is characterised by the absence of inertia and mechanical viscosity as it is executed by the solenoid without any apparent mechanical movernent. Sound emission is therefore effected by firstly agitating the molecules iri space, and secondly, according to the types of methods of winding, can be effected by the sound micro-vibrations of electric wires or solenoids.
A variant of the method is a solenoid added to at Ieast one magnet inside or outside which has its effect but reduces its sensitivity owing to the residual magnetism of the magnetic field of the magnet which imposes its magnetic field constant masking the terrestrial magnetic fieWd.
The invention also relates to a device that improves an audio sound emitted by at least one acoustic baffle, the device delivering an electric signal to the at least one acoustic baffle, the device comprising (i) means for superimposing on the audio sound refined sound information contained in a source signal of the audio sound; and (ii) at least one coil of wire in free ambient air to which is supplied an electric signal, which is the same of the signal of the device delivers to the at least one acoustic baffle, wherein the device is adapted to provide a harmonic amplifying electro-acoustic transducer to supplement at least one of electro-acoustic baffles and a transducer.
