Abstract

The invention consists in using the natural propagation of a loudspeaker (1) in the bass spectrum (2) by positioning it horisontally at head height on a column (3) and of combining it with a medium-high-frequency loudspeaker (4) in vertical position, placed at a distance (5) from the loudspeaker (1). The invention applies to high-fidelity sound reproduction.

Description

La présente invention a pour objet d'améliorer la reproduction du son. The object of the present invention is to improve the reproduction of sound.

Comparativement aux enceintes existantes, le hautparleur principal (1) Fig.l, selon l'invention est monté
horizontalement, le c8ne du haut-parleur (1) visant le plafond.Compared to existing speakers, the main speaker (1) Fig.l, according to the invention is mounted
horizontally, the speaker c8ne (1) aimed at the ceiling.

La hauteur (3) du haut parleur (1) sera comprise entre 90 cm correspondant à un homme assis et 1,70 mètre pour un homme debout.The height (3) of the loudspeaker (1) will be between 90 cm corresponding to a seated man and 1.70 meters for a standing man.

L'Analyse du spectre directionnel (2) d'un haut-parleur montre un écrasement des fréquences dans l'air au fur et à mesure que la fréquence baisse. Pour percevoir les fréquences les plus basses, la position horizontale du haut-parleur (1) devient la plus adaptée. The Directional Spectrum Analysis (2) of a loudspeaker shows an overwriting of frequencies in the air as the frequency decreases. To perceive the lowest frequencies, the horizontal position of the speaker (1) becomes the most suitable.

La position horizontale améliore la tenue mécanique du hautparleur (1) et permet de reproduire des fréquences les plus basses avec haute fidélité.The horizontal position improves the mechanical resistance of the loudspeaker (1) and makes it possible to reproduce the lowest frequencies with high fidelity.

Le diamètre du haut parleur (1) sera adapté au déplacement d'air souhaité. La puissance du haut-parleur (1) sera adaptée à la puissance électrique de la source. Le hautparleur(l) peut étre constitué d'un ou plusieurs haut-parleurs visant le plafond. The diameter of the loudspeaker (1) will be adapted to the desired air movement. The power of the loudspeaker (1) will be adapted to the electric power of the source. The loudspeaker (l) may consist of one or more loudspeakers aiming at the ceiling.

La colonne (4) sera de forme quelconque. La matière utilisée pour la colonne (4) sera de type quelconque. Voici quelques exemples indicatifs
- Bois
-PVC
- Béton
- Fibrociment
- Pierre
- Composite.Column (4) will be of any shape. The material used for column (4) will be of any type. Here are some indicative examples
- Wood
-PVC
- Concrete
- Fiber cement
- Pierre
- Composite.

Le volume de la colonne (4) sera adapté au type du hautparleur (1). La colonne (4) sera close ou accordée suivant les principes bien connus de fabrication des enceintes.The volume of the column (4) will be adapted to the type of speaker (1). Column (4) will be closed or tuned according to the well-known principles of enclosure manufacturing.

En positionnant un haut-parleur (5) Fig.l verticalement sur une face de la colonne à une distance (6) du haut-parleur (1), la couverture des médiums se fera d'une part par le hautparleur (1) et d'autre part par le haut-parleur (5).  By positioning a loudspeaker (5) Fig. L vertically on one side of the column at a distance (6) from the loudspeaker (1), the coverage of the mids will be done on the one hand by the loudspeaker (1) and on the other hand by the speaker (5).

La figure 2 fait apparattre le spectre des médiums. La distance (6) Fig.l doit étre comprise entre 15 et 30 cm pour obtenir l'effet de profondeur du son.Figure 2 shows the spectrum of mediums. The distance (6) Fig.l must be between 15 and 30 cm to obtain the sound depth effect.

La reproduction des aigus peut être confiée au hautparleur (5) Fig.3 ou à un autre haut-parleur (7) placé lui aussi dans les limites (6). Le haut-parleur (7) peut etre au dessus, au dessous ou sur les cOtés du haut-parleur (5). The treble reproduction can be entrusted to the loudspeaker (5) Fig.3 or to another loudspeaker (7) also placed within the limits (6). The loudspeaker (7) can be above, below or on the sides of the loudspeaker (5).

Chaque haut-parleur sera actionné par des filtres bien connus du type : Passif ou Actif. Each speaker will be operated by well-known filters of the type: Passive or Active.

Ce type d'enceinte de haute fidélité peut être utilisé pour toutes les sources de reproduction du son.  This type of high fidelity speaker can be used for all sources of sound reproduction.
