Abstract

It is common to use current filters for electroacoustic transducers, which are generally frequency mixers. Audio electrical signals have pulse response and excellent frequency control. With respect to the electroacoustic transducer, the modification to the electroacoustic transducer is not done properly. The electric pulse travels at the speed of electrons, but the membrane and its motor have a certain weight. The weight has dynamic inertia that hinders the immediate response to electrical effects. The present invention is directed to a method present for modifying at least one modulation of an initial electrical pulse with a micro electrical phase shift. The micro phase shift is caused by the impedance of the device. The device consists of several simple-type elements mounted in parallel, thus forming a magnetic oscillator activated by the initial electrical signal. The device is mounted in a circuit for powering the container.

Description

ELECTRIC SIGNAL PROCESSING FOR ELECTROACOUSTIC TRANSDUCER}

It is common to use current filters for electroacoustic transducers. These filters are usually frequency attenuators with equalizing slopes of 6 Hz, 12 Hz and 18 Hz. The mixer uses a rather complex filter to modify the audio bandwave frequencies. On the other hand, it is common to get the electrical signal curve as complete as possible, i.e. as complete square wave response as possible.

In current technology, audio electrical signals are known to have excellent characteristics in pulse response and frequency stability. In the context of electroacoustic transducers, the conversion of electrical signals is incorrectly performed by the transducer.

In fact, the electric pulses are transmitted at the speed of electrons, but the diaphragm and its driving source constitute an electromechanical assembly having a certain weight. The weight of this mobile assembly has mechanical inertia that hinders the immediate response to the electrical stress of the audio signal, causing distortion, even if the diaphragm cannot respond simultaneously to all electrical values. Lack occurs.

The method of the present invention allows the original electric pulse to be modulated with a micro electric phase shift that shifts at least one modulation, pulses, instantaneous electric pulse into a delayed electric micro-pulse. Therefore, the starting driving force of the motion on the diaphragm is distributed at very short time intervals so that the coil is not saturated by the current, so that the motor of the mechanical assembly in motion is subjected to the original current pulse once the acceleration factor is obtained. Can absorb the rest. These micro-currents are generated by the impedance through which the original electrical signal passes, and electric oscillation occurs by their reverse electric drive force.

These devices are installed in parallel at at least two levels.

Devices installed at three parallel levels respond better to an electrical phase shift for the absorption of the transducer.

Thus, the method of the present invention is to determine the position of the self-feeding oscillator activated by the original audio signal passing through the device configured to achieve an oscillation signal having a very low amplitude and a very large oscillation frequency (FIG. 1). This new signal 2 retains the overall aspect of the original signal 1 which is continuously modulated. Thus, this parallel installation of elements of the same kind but of different values enables the modulation of the audio, digital and electroacoustic transducer supply signals of at least one acoustic transducer or one acoustic speaker. In fact, this method is placed between the amplifier on the power supply line and the acoustic speaker or transducer.

This method does not change the overall curve of the signal at all, but causes micro-interference to the original electrical signal that provides the apparent parasitic shape of the original signal. The elements of this method may be electrical passive elements or active elements, microprocessors, integrated circuits or future technologies.

This method is shown in FIG. 1, where curve 1 of the electrical audio signal is modulated to curve 2 by a method of modulating a completely smooth signal into a signal comprising at least one ripple.

The method also has a device composed of several electrical elements, in this case winding resistors, installed in parallel, as shown in FIG. 2. The first channel 1 consists of at least one element and the second parallel channel 2 consists of at least one element, in this case two elements arranged in series. The third channel 3 is also made up by at least one electrical element, in this case two elements in series. The assembly thus constructed is an interface module mounted between the amplifier 4 and the acoustic speaker 5 and activated by the original electrical signal. The electrical supply wiring 6 of + has an interface module of the present method. In addition to these examples, other examples may be practiced by those skilled in the art. The device, consisting of the same kind of elements with different values, is mounted on any power supply of an acoustic speaker or at least one acoustic transducer.

The method shown in FIG. 3 comprises a first channel 1 having a winding resistor 4 having at least one electrical element, in this case 3.3 kW, and a winding resistor having at least one electrical element, 8.2 kW in this case. It is another example of the process which consists of the 2nd channel 2 which has (6). The third channel 3 is composed of a magnetic induction coil 5 having 18 turns. All elements are installed in parallel in the electricity supply line of at least one electroacoustic transducer 8 of the television connected to the audio generator 7. The values of the elements are micro oscillations similar to some stable interference due to the electrical phase shift caused by the elements acting directly on the supply current of the electrical signal, although the original analog or digital audio signal is not entirely altered by frequency attenuation. Will be affected.

Such a module is an interface device between an analog or digital audio signal and an electroacoustic transducer, which makes it easier to absorb electrical pulses that are converted into mechanical motion (FIG. 3).

It should be noted, however, that this module must not constitute more than 6 kHz attenuation frequency filters.

The method and apparatus of the present invention are to improve the comfortable state of electroacoustic reproduction and to improve the characteristics of acoustic reproduction that can be used in the fields of sound, audio and audiovisual reproduction.
