Title (EN) SPEAKER ENCLOSURE, SPEAKER SYSTEM HAVING THE SPEAKER ENCLOSURE, AND MULTI-CHANNEL STEREO SYSTEM
(FR) ENCEINTE ACOUSTIQUE, HAUT-PARLEUR MULTIVOIE L’UTILISANT ET SYSTÈME STÉRÉO MULTIVOIE
(JA) スピーカエンクロージャ、これを備えたスピーカシステムおよび多チャンネルステレオシステム
Abstract:
(EN) It is possible to provide a speaker enclosure, a speaker system, and a multi-channel stereo system capable of maintaining an excellent phase frequency characteristic and not causing turbulence on a wavefront of an acoustic wave emitted from a speaker unit. The speaker enclosure includes a unit arrangement plane (27) having an arc-shaped cross section similar to a virtual circle R having a center at a standard listening position P on the front surface of a baffle plate (21) or a unit arrangement plane (27) having a partially spherical shape similar to a virtual globe (globe R) having a center at the standard listening position P on the front surface of the baffle plate (21).
(FR) La présente invention concerne une enceinte acoustique, un haut-parleur multivoie et un système stéréo multivoie permettant de maintenir une excellente caractéristique de fréquence de phase et de ne pas créer de turbulence sur un front d’onde d’une onde acoustique émise par une unité de haut-parleur. L’enceinte acoustique comprend un plan d’agencement d’unité (27) à coupe transversale en arc similaire à un cercle virtuel R ayant un centre à une position d’écoute standard P sur la surface avant d’un écran acoustique (21) ou un plan d’agencement d’unité (27) à forme partiellement sphérique similaire à un globe virtuel (globe R) ayant un centre à une position d’écoute standard P sur la surface avant de l’écran acoustique (21).
(JA)  優れた位相周波数特性を維持すると共に、スピーカユニットから放射される音響波の波面に乱れが生ずることのないスピーカエンクロージャ、スピーカシステムおよび多チャンネルステレオシステムを提供することを課題とする。  本発明のスピーカエンクロージャは、バッフル板21の前面に、標準聴取位置Pを中心とする仮想円Rに倣った断面円弧状のユニット配設面27を備え、或いはバッフル板21の前面に、標準聴取位置Pを中心とする仮想球(球R)に倣った部分球面状のユニット配設面27を備えたものである。
