Abstract
Description
Descriotion <U>de l'invention</U> L'invention qui constitue ce dossier concerne le domaine de l'acoustique et ce décompose en deux sous parties A et B. Descriotion <U> of the invention </ U> The invention which constitutes this file relates to the field of acoustics and this decomposes into two subparts A and B.
La partie A est un schéma de câblage dont la décomposition est explicitée figure 2. II s'agit d'un seul et même câble dans lequel nous allons trouver trois conducteurs où une des extrémités sera raccordée au caisson décrit figure 1 au moyen d'un connecteur d'alimentation (4) et l'autre extrémité restante sera connectée â un amplificateur du commerce mono canal monté en pont appelé plus communément amplificateur bridgeable possédant très souvent une fonction nommée LPF (low pass frequency) qui est nécessaire au bon fonctionnement de l'ensemble (cf. notice d'utilisation du matériel concerné). Part A is a wiring diagram whose decomposition is explained in Figure 2. It is a single cable in which we will find three conductors where one of the ends will be connected to the box described in Figure 1 by means of a power connector (4) and the other end will be connected to a commercial single-channel bridge mounted amplifier more commonly called bridgeable amplifier very often having a function called LPF (low pass frequency) which is necessary for the proper functioning of the together (see instructions for use of the equipment concerned).
Pour le choix de ce dernier, il est recommandé de respecter la puissance nominale et l'impédance afin d'avoir une cohérence entre les maillons de cette chaîne et de ne pas donner possibilité à une détérioration quelconque par le manipulateur ou l'intervenant. For the choice of the latter, it is recommended to respect the nominal power and the impedance in order to have a coherence between the links of this chain and not to allow any possibility of deterioration by the manipulator or the speaker.
La partie B est un modèle possible de réalisation de caisson de basses avec un matériaux qui est le médium (matériaux se situant entre l'Isorel mou et le contre plaqué). Cette boite sans couvercle à l'aspect compact, discret et efficace, où la cotation est directement liée aux diamètres des haut-parleurs (1) et (2) est facile à mettre en oeuvre en terme de fabrication et de prix de revient. Part B is a possible model for making a subwoofer with a material that is the medium (materials lying between the soft Isorel and the plywood). This lidless box with compact appearance, discreet and efficient, where the quotation is directly related to the diameters of the speakers (1) and (2) is easy to implement in terms of manufacturing and cost.
<B><U>Explication et fonctionnement</U></B> Par le connecteur d'alimentation (4) nous recevons un signal audio prêt à l'emploi délivré par l'amplificateur qui va nous servir à alimenter la paire de haut-parleurs (1) et (2) monté en opposition de phase ; de ce fait, si on observe le phénomène lors d'une impulsion positive la membrane du haut-parleur (2) tend à pousser celle du haut-parleur (1) au biais d'un volume d'air emprisonné, de plus cette même impulsion traverse aussi la bobine du haut- parleur (1). L'ensemble du déplacement de ces membranes fournit un son qui est lissé par une portion d'exponentielle (3) sortant par l'évent. Dispositif concernant le domaine de la sonorisation moderne ayant comme valeur ajoutée un schéma unique de branchement reposant sur des lois générales de l'électricité bien connues par les électriciens et électroniciens qui sont la loi de Lenz d'une part, et la loi d'ohm d'autre part, un modèle de caisson de basse à la particularité d'utiliser deux haut-parleurs(ou plusieurs, en les clonant sur la première paire) celui-ci a pour but d'améliorer la qualité du son dans les basses fréquences. <B> <U> Explanation and operation </ U> </ B> </ B> </ B> By the power connector (4) we receive a ready-to-use audio signal from the amplifier that will be used to power the pair of loudspeakers (1) and (2) mounted in phase opposition; therefore, if one observes the phenomenon during a positive pulse the membrane of the loudspeaker (2) tends to push that of the speaker (1) through a volume of air trapped, more that same impulse also passes through the speaker coil (1). The entire displacement of these membranes provides a sound that is smoothed by an exponential portion (3) exiting through the vent. Device relating to the field of modern sound system having as added value a single connection diagram based on general electricity laws well known by electricians and electronics who are the law of Lenz on the one hand, and the law of ohm on the other hand, a subwoofer model with the particularity of using two speakers (or more, by cloning them on the first pair) this one aims to improve the quality of the sound in the low frequencies .
Le schéma s'applique facilement et aisément à la plus part des chaînes de sonorisation haute fidélité utilisant un filtrage actif et une source irréprochable, sans oublier bien entendu la fiabilité de tout autres préamplificateurs et amplificateurs de puissance. Les avantages qui résultent de cette conception sont la diminution de la section des cordons reliant cette fameuse enceinte de forme cubique à l'étage d'amplification à cause d'une finalité purement résistive où le travail restitué apparaît par l'effet joule. The schema is easily and easily applied to most high-fidelity sound systems using active filtering and an irreproachable source, without forgetting of course the reliability of any other preamplifiers and power amplifiers. The advantages that result from this design are the reduction of the section of the cords connecting this famous cube-shaped enclosure to the amplification stage because of a purely resistive purpose where the work restored appears by the joule effect.
Le rendement et la consommation énergétique fort aussi partie des atouts non négligeables du fait des propriétés des matériaux utilisés pour la légèreté des membranes à qui la proportionnalité de leurs surfaces vont être directement liés au carré de la vitesse. Efficiency and energy consumption are also important assets because of the properties of the materials used for the lightweight membranes whose proportionality of their surfaces will be directly related to the square of the speed.
La distorsion harmonique est nettement atténuée grâce l'emprisonnement d'un volume d'air entre la paire de haut-parleurs. Harmonic distortion is greatly reduced by trapping a volume of air between the pair of speakers.
Les domaines d'applications se situent au centre des pièces de concerts, ou autres salles de cinémas, voire palais des sports en passant par les sonorisations des véhicules sans oublier que l'effet reproduit sera néanmoins différent et variable du fait de la propagation des ondes par rapport au volume même de cet habitacle, ou enceintes de spectacle.The areas of application are at the center of the concert halls, or other cinemas, even sports halls through the sound systems of the vehicles without forgetting that the effect reproduced will nevertheless be different and variable because of the propagation of the waves compared to the same volume of this cabin, or show speakers.
