Title (EN) INDEPENDENT SOUND FIELD-FORMING DEVICE IN VEHICLE
(FR) DISPOSITIF DE FORMATION DE CHAMP SONORE INDÉPENDANT DANS UN VÉHICULE
(KO) 차량 내 독립 음장 형성 장치
Abstract:
(EN) An independent sound field-forming device according to an embodiment of the present invention may comprise: an A/D converter for converting, to a digital signal, a first sound source signal from an AVN device, for a vehicle, having a sound output means having N channels; a communication unit for receiving, from a mobile terminal, a user input including information on a first focusing area selected from a plurality of focusing areas; a storage unit for storing a first filtering coefficient for converting the first sound source signal such that sound is focused on the first focusing area; a processor for generating a first digital sound signal for the N channels by converting the digital signal from the A/D converter on the basis of the first filtering coefficient; and a D/A converter for converting the first digital sound signal for the N channels to an analog signal for the N channels and outputting same to the sound output means having the N channels.
(FR) Un dispositif de formation de champ sonore indépendant selon un mode de réalisation de la présente invention peut comprendre : un convertisseur A/N pour convertir, en un signal numérique, un premier signal de source sonore provenant d'un dispositif AVN, pour un véhicule, ayant un moyen de sortie de son ayant N canaux ; une unité de communication pour recevoir, en provenance d'un terminal mobile, une entrée d'utilisateur comprenant des informations sur une première zone de mise au point sélectionnée parmi une pluralité de zones de mise au point ; une unité de stockage pour stocker un premier coefficient de filtrage pour convertir le premier signal de source sonore de telle sorte que le son est focalisé sur la première zone de focalisation ; un processeur pour générer un premier signal sonore numérique pour les N canaux par conversion du signal numérique provenant du convertisseur A/N sur la base du premier coefficient de filtrage ; et un convertisseur N/A pour convertir le premier signal sonore numérique pour les N canaux en un signal analogique pour les N canaux et les délivrer au moyen de sortie sonore ayant les N canaux.
(KO) 본 발명의 실시예에 따른 독립 음장 형성 장치는 N채널의 음향출력수단을 갖는 차량용 AVN 장치로부터의 제 1 음원신호를 디지털신호로 변환하는 A/D 컨버터, 모바일 단말로부터 복수의 포커싱 영역 중에 선택된 제 1 포커싱 영역에 관한 정보가 포함된 사용자 입력을 수신하는 통신부, 상기 제 1 포커싱 영역에서 음향이 집중되도록 상기 제 1 음원신호를 변환하기 위한 제 1 필터링 계수를 저장하는 저장부, 상기 제 1 필터링 계수에 기초하여, 상기 A/D 컨버터로부터의 디지털신호를 변환하여 N채널의 제 1 디지털 음향신호를 생성하는 프로세서 및 상기 N채널의 제 1 디지털 음향신호를 N채널의 아날로그신호로 변환하여 상기 N채널의 음향출력수단으로 출력하는 D/A 컨버터를 포함할 수 있다.
