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. Mixers use rather complex filters 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 pulse response and frequency control characteristics. With regard to electroacoustic transducers, the alteration of the electrical signal is incorrectly performed by the transducer.

In fact, electric pulses are transmitted at the speed of electrons, but the diaphragm and its motor constitute an electrodynamic assembly of some weight. The weight of this moving assembly has a dynamic inertia that hinders the immediate response to the audio signal, thereby causing distortion, and even lack of sound when the diaphragm cannot respond simultaneously to all electrical values. .

This process allows the first electric pulse to be modified with a micro electric phase shift that shifts at least one modulation, pulse, instantaneous electric pulse into a delayed electric micro-pulse. Thus, the starting driving force for movement over the diaphragm is distributed in a very short time so that the coil is not saturated by the current, so that the motor of the moving dynamic assembly will absorb the rest of the initial current pulse once the acceleration index is obtained. Can be. These micro-currents are generated by the impedance across the original electrical signal, and generate electrical oscillations by their reverse electric drive force.

These devices are mounted in parallel on at least two levels.

Devices mounted at three parallel levels respond well to the electrical phase shift for the electrical absorption of the transducer.

Thus, this process is to determine the position of the self-oscillating oscillator activated by the first audio signal across the device that is close to the oscillating signal with a very low amplitude and very large frequency oscillation (FIG. 1). This new signal 2 maintains the overall shape of the original signal 1 which is continuously modulated. Thus, this parallel mounting process of elements of the same shape but of different values enables the modification of the audio, digital and electroacoustic transducer supply signals of at least one acoustic transducer or one acoustic speaker. In fact, this process is located between the amplifier on the supply line and the acoustic speaker or transducer.

This process creates micro interference in the first electrical signal that does not change the overall curve of the signal at all, but provides the apparent parasitic shape of the original signal. The devices of such a process may be electrically passive or active devices, microprocessors, integrated circuits or future technologies.

This process is represented by FIG. 1 and curve 1 of the electrical audio signal is modified to curve 2 by the above process of correcting the complete smoothing signal to at least one ripple signal.

This process also has a device consisting of several electrical elements, in this case a winding resistor mounted in parallel (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 mounted in series. The third channel 3 is also made up of 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 initial electrical signal. The supply wiring 6 of + has the interface module of the said process. Indefinite examples are made by those skilled in the art. The device, which consists of elements of the same type with different values, is mounted in any power supply of an acoustic speaker or at least one acoustic transducer.

The process of FIG. 3 comprises a channel 1 having a winding resistor 4 with at least one electrical element, in this case 3.3 kV, and a winding resistor 6 with at least one electrical element, in this case 8.2 kV. It is an alternative example of the process which consists of the channel 2 which has. The channel 3 is composed of a magnetic induction coil 5 having 18 turns. All the elements are mounted in parallel to the supply line of at least one electroacoustic transducer 8 of the television connected to the audio generator 7. The values of the elements are similar to slightly stable interference due to the electrical phase shift caused by the elements directly intervening due to their shape in the supply current of the electrical signal, although the original analog or digital audio signal is not entirely changed by the frequency attenuation. It is enough to make micro oscillation.

Such a module is an interface device between an analog or digital audio signal and an electroacoustic transducer that enables the mechanical operation to absorb electrical pulses that are more readily modified (FIG. 3).

Note that this module should not constitute more than 6 kHz attenuation frequency filters.

This process and apparatus is intended to improve the comfortable state of electroacoustic reproduction and to improve the properties of acoustic reproduction that can be used in the fields of sound, audio and audiovisual reproduction.
