Breakthrough

The AudioTransformer Technology is one of the greatest if not the greatest invention in the third millennium. In sound technology, efficiency of the electronic parts manufactured by the AudioTransformer technology shows a very significant increase relative to the electronic parts manufactured by other technologies. Nonetheless, a significant improvement in sound quality and a reduction in electricity consumption of the system may be achieved simultaneously by the insertion of even a single AudioTransformer element.

The Base

The Magnetic Induction

The electromagnetic induction was observed about 1820, when a relatively large number of inventors made apparatuses working under this principle.

The law of induction was framed by Michael Faraday (1791-1867), an English physicist in 1831. The essence of this invention is that a time-varying voltage is generated i.e. induced in each electric wire, which is placed in a time-varying magnetic field. This phenomena is called induction.  Magnetic induction may be generated in several ways, but in any case, a time-varying magnetic field shall be present near the wire. If so, than a time-varying voltage is created (induced) in the wire. Three types of magnetic induction are known:

  • Motional induction
  • Static induction
  • Self-induction

In general, these three factors with the Lenz’s law added work together under conditions changing in every moment.

The Transformer

The transformer was invented in 1885 by three Hungarian scientists, Déry Miksa (1854-1938), Bláthy Ottó (1860-1939) and Zipernovszky Károly (1853-1942). The invention made is possible to conduct electric current over long distances from the place of generation. Previously, at the time of Edison and Siemens, electric current could be conducted over a maximum distance of 100m.

The referred scientists used the Farady’s invention of magnetic induction so as to be of human scale and to benefit all of us in practice. Two coils were placed near to each other so that the magnetic field lines was prevented from dispersal by a high permeability material instead of air.  This single change increased inductivity a thousandfold in comparison to the original value. On the first try, they created a piece of equipment, whose efficiency was more than 90%. Thanks to this invention, it became possible to conduct electric current extremely economically over long distances, even thousands of kilometres. Still today, this piece of equipment is used between electricity powerplants and consumer points.

The Electric Motor

From 1920, many introduced an electric motor, inter alia Michael Faraday, an English physicist, but Jedlik Ányos, a Hungarian Benedictine monk, naturalist as well. The first electric motors were born well before the Faraday’s law. They were made empirically by using the electromagnetic induction. They were presented under names such as "multiplier turning around an electromagnet with current transformation" and the like. Actually, an electric motor has two coils like a transformer has, except the only difference that the two coils are able to move relative to each other. Placed so as to face each other, several pairs of coils are put in a circle. If a varying voltage is used to generate induction in one of the facing coils, then according to Lenz’s law, an opposite voltage is induced in the other. If the two ends of the latter coil are connected together, then a current will flow in the coil and since the direction of this current is reverse to that of the exciting current in the other coil, the two coils will attract each other. If the induction is generated in the exciting coils with a time shift, then an excited rotational magnetic field is obtained. If the facing coils aren't allowed to move in the middle, then they will rotate on the outside, while if they are fixed on the outside, then the coils placed inside will rotate. Up to this point, the processes occurring in the transformer according to the laws of static induction are described.

Problems

electric motor

As regards the transformer described above, if the excited coil is short-circuited, then an enormous heat is generated in the transformer, causing it to burn out.

It’s an obvious question that why doesn’t it burn out in the electric motor, where the excited coil is short-circuited?

Well, it doesn’t burn out, since the coil excited with static induction in the electric motor is moving. If it’s moving, then another phenomenon appears together with the excited voltage (U=N*Dj/Dt). This phenomenon is the motional induction. According to Faraday’s interpretation, voltage of the motional induction is U=N*B*L*v. If the two coils are fixed both inside and outside, then they can’t move, consequently no motional induction appears. If there’s no motional induction, then according to Lenz’s law, no reverse voltage is induced, which could, via a reverse current, prevent the unrestricted travel of the exciting current through the system, whereby a high current causing the electric motor to become hot and burn out is generated. If this electric motor (rotating transformer) is allowed to rotate in its own comfort zone, then electric power may be converted into mechanical work with an efficiency of more than 90%.

loudspeaker

  • the efficiency of a loudspeaker that has a sensitivity of 92 dB is 1%;
  • the sound intensity of a falling leaf is very close to 0dB, that is total silence, which needs a power of 10-12 watt.
  • The human ear can’t hear a sound intensity difference of less than 3dB, though such an increase in sound intensity requires the double of the electric power related to the previous sound intensity. So 1watt power requirement is achieved at 92dB, which is the value of sensitivity measured at 1m distance. Public address systems aim to reach an acoustic pressure of 117dB. An acoustic pressure of 120dB may cause permanent hearing loss. Even a 117dB load on the human ear can be applied only intermittently.
  • Let’s say we have a home audio system with an electricity consumption of 200 watts. Since a party will be held, we buy a 400 watt audio system. It would be a serious mistake to think that a double sound intensity will be present at the party. The sound intensity will be higher almost imperceptibly. This is also the case, if we change our 3,000 watt home audio system. If changing it for a 5,000 watt type, we won’t even notice the increase in acoustic intensity, since a bit more loudness would be heard only at 6,000 watts. This is due to the specific exponential characteristic of the human ear. This characteristic ensures that we can hear even the whisper, but even a clap of thunder will not destroy our ears.
  • In summary, if 12,000 watt power is used for public address in a hall, then due to the loudspeakers’ efficiency, only 120 watts are used for public address, while 11,880 watts are converted to heat.
  • The question is whether there’s an audio set-up, which in case of the same sound intensity, consumes nearly 100 times less power than the present audio system. Yes, there is! That’s the AudioTransformer.

The first problem with currently produced loudspeakers is that efficiency of the currently produced loudspeakers is 1% or a bit more or even less as the load is increased.

The second problem with currently produced loudspeakers follows directly from the first problem. Let’s just think about, if hundredfold electric power shall be supplied to generate sound from at least 1 per cent of it, then harmful consequences mustn’t be avoided. A harmful consequence is that the loudspeaker will radiate self-generated direct current signals. These generated signals will actuate the loudspeaker membrane, but otherwise as expected. It will produce absolutely hysterical motions, clearly visible to the naked eye. These visible motions have no audible sound, however by their direct current character, they consume extraordinary electric power, while divert the loudspeaker membrane from its comfort zone. The consequence is that

  • the loudspeaker consumes a lot of electric power, while
  • the loudspeaker sound will have a very poor quality. It will radiate a quasi self-excited sound rather than the sound of singers and musical instruments.

Epiphany

The Soundtransformer

For the loudspeaker, electric signals are amplified, then inputted to the moving (swinging) coil, which were generated previously from sounds so that this sound  is caused to carry out mechanical work and by using this work, electromagnetic motional induction is generated. Having generated by electromagnetic motional induction, these electric signals are amplified, then reconverted to mechanical motion in the loudspeaker via motional induction. The mechanical motion generates the sound, which becomes perceptible with the mediation of acoustic waves created by the vibration of the loudspeaker membrane.

It’s an essential question whether what proportion of the available electrical signals is converted to sound. And what happens to the electrical signals, which is not converted to sound. Everybody knows that those electrical signals become heat... This proportion is called efficiency.

What’s the solution?

The solution is the Soundtransformer Technology!

The Soundransformer audio system is a piece of equipment produced by the Soundtransformer Technology, which combines the operation of the transformer and the electric motor. The efficiency of more than 90% is reached by this special technology named as Soumdtransformer Technology.

The Soundtransformer technology is used to produce loudspeakers, which

  • has an extraordinary low power consumption;
  • radiates the musical instruments’ and the performers’ own sound.

The Soundtransformer Technology allows for the coil moving (swinging) in the magnetic field, which moves like a motor via electric signals generated from the sound by the means of magnetic induction to move in the magnetic field as a generator too, which generator creates a voltage of reverse direction than that of the exciting voltage. As a result, only an amount of current allowed by the difference between the exciting voltage and the voltage generating from the motional induction will flow in the system. Since one of the voltage is U=N*Dj/Dt and the other is U=N*B*L*v, where N, B, L and v are the same, the voltage difference shall not be more than the one caused by the loudspeaker membrane resistance to air and the moving mass inertia as a phase lag.

In addition to the low electric power consumption, a sound of such a plasticity is resulted, which expression is used by mankind for the colours of Michelangelo alone.

The AudioTransformer Technology is one of the greatest if not the greatest invention in the third millennium. In sound technology, efficiency of the electronic parts manufactured by the AudioTransformer technology shows a very significant increase relative to the electronic parts manufactured by other technologies. Nonetheless, a significant improvement in sound quality and a reduction in electricity consumption of the system may be achieved simultaneously by the insertion of even a single AudioTransformer element. Some preferred application areas are included but not limited to the following:

  • Manufacture of loudspeakers;
  • Manufacture of guitar pickups;
  • Manufacture of microphone cables and XLR cables (analogue signal transmission cables);
  • Unbalanced guitar cables;
  • Power supply cables.
