Title (EN) ACOUSTIC REPRODUCTION DEVICE
(FR) DISPOSITIF DE REPRODUCTION ACOUSTIQUE
(JA) 音響再生装置
Abstract:
(EN) Provided is a lightweight acoustic reproduction device. This acoustic reproduction device is provided with a plurality of flat speakers 11, the plurality of flat speakers 11 being disposed such that normals to sound emitting faces thereof cross each other at a common listening position P. Preferably, the plurality of flat speakers 11 are supported by a support 100 having a shape of a truncated icosahedron, and respectively disposed on a plurality of regular pentagonal faces of the truncated icosahedron. Preferably, the center of the support 100 is the listening position P at which the head of a listener is located.
(FR) L'invention concerne un dispositif de reproduction acoustique de faible poids. Ce dispositif de reproduction acoustique est pourvu d'une pluralité de haut-parleurs plats (11), la pluralité de haut-parleurs plats (11) étant disposés de sorte que leurs normales aux faces d'émission de son se croisent à une position d'écoute commune P. De préférence, la pluralité de haut-parleurs plats (11) sont supportés par un support (100) présentant une forme d'un icosaèdre tronqué, et disposés respectivement sur une pluralité de faces pentagonales régulières de l'icosaèdre tronqué. De préférence, le centre du support (100) est la position d'écoute P au niveau de laquelle se trouve la tête d'un auditeur.
(JA) 軽量な音響再生装置が提供される。この音響再生装置は、複数の平面スピーカ11を備え、複数の平面スピーカ11は、それぞれの放音面の法線が共通の受聴位置Pにおいて交差するように配置されている。好ましくは、複数の平面スピーカ11は、切頂二十面体の形状を有する支持体100に支持され、切頂二十面体の複数の正五角形の面にそれぞれ配置される。好ましくは、支持体100の中心は、聴者の頭部が位置する受聴位置Pとなる。
