MXPA01007784A - Improvements in sounds reproduction. - Google Patents

Abstract

This invention relates to the spatial production of sounds. The correspondent and necessary electrical signals for its correct processing by means of audio equipment can be originated in real scenes such as radio, television etc. Unlike stereo sound, which disposes of a place for hearing correctly, requiring two audio channels; the present invention produces the spatial sensation of sound origin in a plurality of places, using a single audio channel. Said channel processes electric signals correspondent to the desired sound produced, applying them to two speakers so that each can emit to the other the generated sound, for this reason both have to face each other. The interference of sounds produced like this in a space zone between the two speakers, creates the sound origin spatiality.

Description

IMPROVEMENTS IN SOUND REPRODUCTION BACKGROUND OF THE INVENTION Culminating a long journey of improvements in the reproduction of sounds, came the stereophonic system, which produces the sensation of a spatial distribution of sound. However, there is only one correct position to achieve the stereophonic effect. The improvement that is intended to protect, through the present application, produces the sensation that: the sound that is heard is spatially distributed and, unlike the stereophonic sound that associates an ideal position to perceive the spatial effect, this improvement achieves that this effect is perceived, from a plurality of places. Therefore, by applying the improvement to the audio signals of a television, or of a movie, etc. , it is possible to give the sound a spatial origin that increases the realism of the scenes.

DESCRIPTION OF THE INVENTION It is an improvement in the reproduction of sounds, which consists of increasing the intensity of sound in a zone of space, to produce the spatial sensation of its origin, in a plurality of places. The source of the sound in question may come from a recording, a radio signal, a television, a live show, etc. The electrical signal corresponding to the sound and processed by an audio amplifier must be applied to two facing speakers, so that they emit the same sound towards each other; the input signal may result from a mixture of signals, such as: stereo signals. The midpoint of the line that joins the speakers must be within area d where the intensity of the sounds should be increased; When the sound waves emitted by the loudspeakers are found and capable of interfering, the intensity of the sound sought is increased. Depending on the circumstances, either because of the volume of space that needs to be filled with the sound, or because of the quality that it must have, it is more convenient to use an amplifier or audio channel per speaker, since it would have twice the power in the first case and of less distortion in the second, if the two channels are used at low levels, but with sufficient power. The speakers must be adequately separated, so that the sound they generate is perceived in a plurality of places.

Claims (1)

1. CLAIMS Having sufficiently described my invention, I consider it a novelty and therefore claim as my exclusive property, what is contained in the following - Clauses. Improvements in the reproduction of sounds, which are characterized by two facing speakers, which emit each one towards the other, the sound that is wanted to reproduce to create a sense of spatiality of the origin of its undulations, which will be perceived in a plurality of places. Each speaker is connected to the same electrical signal that corresponds to the mentioned sound, with the purpose of causing the interference of the sound waves between the speakers; the increase in sound intensity, thus achieved, gives rise to the sensation of spatiality sought. Improvements in the reproduction of sounds, as claimed in the previous clause, characterized by the addition of an amplifier whose output is applied to each of the speakers faced. Improvements in the reproduction of sounds, as claimed in clause 1, characterized by the addition of two audio amplifiers; one for each of the speakers facing each other; The input signal of the amplifiers can be the same for the two amplifiers, or different if the reproduction is stereo.
