Title (EN) VEHICLE-MOUNTED ACOUSTIC DEVICE
(FR) DISPOSITIF ACOUSTIQUE EMBARQUÉ SUR VÉHICULE
(JA) 車載音響装置
Abstract:
(EN) The objective of the present invention is to control the output of a sound beam in the interior of a vehicle in accordance with the state of the interior of the vehicle. In the interior of a vehicle 100, a speaker array device 14 provided with a speaker array 145 in which a plurality of speakers are arranged is provided on an upper surface of a dashboard 133. A vehicle-mounted acoustic device 10 determines the status of occupants (for example the number of occupants and the positions in which the occupants are sitting) present in the interior of the vehicle 100. The vehicle-mounted acoustic device 10 supplies an input sound signal to some or all of the plurality of speakers in the speaker array 145 with timings corresponding to the status of the occupants, thereby causing a sound beam to be output by the speaker array device 14. The sound beam reaches the positions of the occupants either directly or having been reflected from glass members (for example side windows 122) provided in the vehicle 100.
(FR) L'objectif de la présente invention est de commander la production d'un faisceau sonore à l'intérieur d'un véhicule en fonction de l'état de l'intérieur du véhicule. Dans l'intérieur d'un véhicule (100), un dispositif à ensemble de haut-parleurs (14) pourvu d'un ensemble de haut-parleurs (145) dans lequel une pluralité de haut-parleurs est agencée est situé sur une surface supérieure d'un tableau de bord (133). Un dispositif acoustique embarqué sur véhicule (10) détermine l'état de passagers (par exemple le nombre de passagers et les positions dans lesquelles les passagers sont assis) présents à l'intérieur du véhicule (100). Le dispositif acoustique embarqué sur véhicule (10) fournit un signal sonore d'entrée à une partie ou à la totalité de la pluralité de haut-parleurs dans l'ensemble de haut-parleurs (145) avec des synchronisations correspondant à l'état des passagers, ce qui provoque la production d'un faisceau sonore par le dispositif à ensemble de haut-parleurs (14). Le faisceau sonore atteint les positions des passagers soit directement soit par réflexion par des éléments en verre (par exemple des vitres latérales (122)) présents dans le véhicule (100).
(JA) 車両の車室における音声ビームの出力を、車室の状況に応じて制御する。 車両100の車室において、複数のスピーカを配列したスピーカアレイ145を備えたスピーカアレイ装置14が、ダッシュボード133の上面に設けられている。車載音響装置10は、車両100の車室に存在する乗員の状況(例えば、乗員の数や、乗 員が着席した位置)を判定する。車載音響装置10は、入力された音声信号を、乗員の状況に応じたタイミングでスピーカアレイ145の複数のスピーカの一部又は全てのスピーカに供給することで、スピーカアレイ装置14によって音声ビームを出力する。音声ビームは、直接又は車両100に設けられたガラス部材(例えば、サイドウィンドウ122)で反射して、乗員の位置に到達する。
