(특허 문헌) 일본특허공개 제2005-165350호
본 발명은 텔레비전 장치에 관한 것이다.
최근, 액정 디스플레이(liquid crystal display;LCD), 플라즈마 디스플레이 또는 유기 EL(organic eletro-luminescence) 디스플레이를 포함하는 박판형 디스플 레이 패널, 사운드 출력을 위한 스피커, 및 디스플레이 패널과 스피커를 그 안에 설치하는 하우징(housing)을 구비하는 텔레비전 장치가 제공되어 왔다(특허 문헌 1 참조).
그러나, 스피커들이 디스플레이 패널의 좌측, 우측, 및 아래에 설치되므로, 상기 텔레비전 장치는 그것의 디자인에서의 제한사항과, 그것의 디자인과 미적인 면을 향상시키기 위한 노력에서 한계가 있다.
본 발명은, 일본특허공개 제2005-333279호에 개시된 바와 같이, 플로팅(floating) 텔레비전 디스플레이의 부유감을 사용자에게 제공하는 새로운 디자인의 텔레비전 장치를 제안한다.
개시된 텔레비전 장치는, 박판형 텔레비전 디스플레이 장치, 디스플레이 장치에 배치된 제1 스피커, 일 장소에 배치된 장착부, 장착부로부터 위로 돌출한 장착부로부터 이격된 상부에서 디스플레이 장치를 그 자세를 변경가능하도록 지지하는 지지 메커니즘, 및 장착부에 배치되는 제2 스피커를 포함한다.
텔레비전 장치는 사용자가 플로팅 디스플레이 장치의 부유감을 갖고, 디스플레이 장치가 그 자세를 변경하도록 하는 방식으로 디스플레이 장치를 지지하도록 한다. 디스플레이 장치가 장착부의 앞으로 크게 당겨지면, 사용자의 귀로부터 제2 스피커로의 거리는 사용자의 귀로부터 제1 스피커로의 거리보다 더 멀어지게 된다.
그러므로, 제1 스피커로부터 출력된 사운드는, 제2 스피커로부터 출력된 사운드가 사용자의 귀에 도달하는 것보다 더 일찍 사용자의 귀에 도달하여, 사용자가 불편하고 부자연스럽게 느끼도록 한다.
본 발명의 일 실시예에 따르면, 양질의 사운드를 재생하는 데에 효과적인 텔레비전 장치를 제공하는 것이 바람직하다.
본 발명의 일 실시예에 따르면, 텔레비전 장치는, 박판형 디스플레이 장치, 일 장소에 배치되도록 적응되는 장착부, 장착부로부터 위로 돌출한 장착부로부터 이격된 상부에서 디스플레이 장치를 그 자세를 변경가능하도록 지지하는 지지 메커니즘, 디스플레이 장치에 장착된 제1 스피커, 장착부에 장착되는 제2 스피커, 제1 스피커에 제1 오디오 신호를 공급하고 제2 스피커에 제2 오디오 신호를 공급하는 신호 공급부, 및 신호 공급부로부터 제1 오디오 신호 출력의 타이밍과 신호 공급부로부터 제2 오디오 신호 출력의 타이밍 사이에 시간 차이를 조정하는 신호 처리기를 포함한다.
본 발명의 상술된 그리고 다른 특징과 이점이, 예를 통해 본 발명의 선호되는 실시예들을 설명하는 첨부 도면과 함께 고려될 때 다음 설명으로부터 명백해질 것이다.
<실시예>
본 발명의 실시예들에 따른 텔레비전 장치는 도면을 참조하여 아래 상세히 기재될 것이다.
제1 실시예:
도 1은 본 발명의 제1 실시예에 따른 텔레비전 장치(10)의 투시도를 나타낸 다.
도 1에 도시된 바와 같이, 텔레비전 장치(10)는, 디스플레이 장치(12), 디스플레이 장치(12)를 지지하는 스탠드(20), 제1 스피커(50), 제2 스피커(52), 및 거리 검출기(54)를 포함한다.
우선, 디스플레이 장치(12)가 아래 설명될 것이다.
도 1에 도시된 바와 같이, 디스플레이 장치(12)는 박판형 디스플레이 장치(1202), 프레임(1204), 및 디스플레이 구동 회로(1210)를 포함한다(도 8 참조).
디스플레이 장치(1202)는 한 쪽에 디스플레이 표면과 다른 쪽에 뒷면을 갖는다. 디스플레이 장치(1202)의 한 면은 앞면으로서 지칭되고, 그것의 다른 면은 뒷면으로서 지칭된다.
프레임(1204)은 디스플레이 장치(1202)의 뒷면을 덮는 박판형 판의 형태로 디스플레이 장치(1202)를 지지한다.
본 실시예에서, 디스플레이 장치(1202)는 유기 EL 디스플레이를 포함한다. 그러나, 디스플레이 디바이스(1202)는 플라즈마 디스플레이 또는 액정 디스플레이를 포함할 수 있다.
스탠드(20)는 아래 설명될 것이다.
도 1에 도시된 바와 같이, 스탠드(20)는 베이스(22), 지지대(24), 암(26), 및 평형추(28)를 포함한다. 본 실시예에서, 베이스(22)는 일 장소에 배치되는 장착부로서 역할을 한다.
지지대(24)는 베이스(22)로부터 위로 돌출하고, 암(26)은 지지대(24)의 윗단 에 지지되는 세로 방향의 중간 부분을 갖는다. 디스플레이 장치(12)는 암(26)의 앞단에 지지되고, 평형추(28)는 암(26)의 뒷단과 결합된다.
베이스(22)는 프레임과, 프레임을 덮는 덮개(2202)를 포함한다.
반구 지지체(30)는, 수직 축에 대한 선회 조절 움직임과 수직 방향에서의 요동 조절 움직임을 위해 프레임의 위쪽 부분에 배치된다. 지지체(30)는 덮개(2202)의 위 표면으로부터 윗 쪽으로 노출된다. 지지대(24)는 지지체(30)로부터 돌출된다. 본 실시예에서, 지지대(24)는 서로 간에 평행으로 연장된 2개의 봉(rods;2402)을 포함한다.
종래 기술의 선회(turning) 메커니즘과 수직요동 메커니즘이 프레임과 지지체(30) 사이에 제공된다. 선회 메커니즘과 수직요동 메커니즘과 연관되어 지지체(30)를 특정하게 선회되고 수직요동된 상태로 유지하기 위해 마찰 메커니즘이 또한 제공된다. 사용자가 디스플레이 장치(12) 또는 지지대(24)를 원하는 자세로 선회하거나 수직으로 스윙하고나서, 디스플레이 장치(12) 또는 지지대(24)를 릴리스(release)할 때, 프레임에 대한 지지대(24)의 각도가 유지된다.
도 2는 지지대(24)와 암(26) 사이의 접합부를 나타내는 확대된 측면도이고, 도 3은 도 2의 화살표 E의 방향으로 본 도면이고, 도 4는 도 3의 F-F 선에 따른 단면도이고, 도 5는 도 3의 G-G 선에 따른 단면도이다.
도 4 및 도 5에 도시된 바와 같이, 암(26)이 지지대(24) 상에 수직요동하게 지지되는 수직요동 메커니즘(33), 토션 코일 스프링(torsion coil spring;32), 및 마찰력 하에 지지대(24)에 대해 수직요동된 상태로 암(26)을 유지하는 마찰 메커니 즘(34)을 병합하는 접합부에서, 지지대(24)와 암(26)이 서로 접합된다.
토션 코일 스프링(32)은, 디스플레이 장치(12)의 중량에 기초하여 지지대(24) 상에서 동작하는 회전 모멘트와, 평형추(28)의 중량에 기초하여 지지대(24) 상에서 동작하는 회전 모멘트를 균형있게 유지하기 위한 역할을 한다. 지지대(24)와 암(26) 사이의 접합부에서, 평형추(28)의 중량에 의해 발생되는 회전 모멘트와 함께 토션 코일 스프링(32)의 반동에 의해 발생되는 회전 모멘트는, 디스플레이 장치(12)의 중량과 암(26)의 중량에 의해 발생되는 회전 모멘트에 반작용한다.
도 2 내지 도 5에 도시된 바와 같이, 2개의 봉(2402)의 선단에 대향하여 브래켓(bracket;2404, 2406)이 설치된다. 수 나사 부재(2408)는 브래켓(2404, 2406) 사이를 통과하여 연장된다. 암(26)의 중간 부분으로부터 돌출된, 큰 마찰 계수를 갖는 재료로 만들어진 평판 부재(tabular member;2602)는, 브래켓(2404, 2406) 사이에 샌드위치되어 있고, 수 나사 부재(2408)의 축부(shank) 상에서 회전되게 지지되어, 수직요동 메커니즘(33)을 제공한다.
평판(2602)은, 수 나사 부재(2408)의 축부가 연장되는 내부 관부(2604)와, 반경방향 외측으로 배치되어 내부 관부(2604)에 접합되는 외부 관부(2606)를 구비한다. 외부 관부(2606)는, 브래켓(2404, 2406)의 외부 직경과 실질적으로 같은 외부 직경을 갖는다.
토션 코일 스프링(32)은 내부 관부(2604)와 외부 관부(2606) 사이에 환형의(annular) 공간에 배치된다. 토션 코일 스프링(32)은 브래켓(2404)의 벽 면(2410)과 맞물린 일단(3202)과, 도 4에서 점선 화살표에 의해 표시된 것과 같은 토션 코일 스프링(32)의 바이어스에 대향하여 배치되는 평판(2602)의 벽 면(2610)과 맞물리는 타단(3204)을 구비한다. 토션 코일 스프링(32)은 지지대(24)와 암(26) 사이에서 수 나사 부재(2408)의 원주 방향으로 작용하는 그것의 탄성력을 인가한다.
수 나사 부재(2408)가 느슨해지거나 또는 죄어졌을 때, 브래켓(2404, 2406) 사이의 평판 부재(2602)를 죄는 경향이 있는 힘이 조정된다, 즉, 브래켓(2404, 2406)과 평판 부재(2602) 사이에 발생되는 마찰력이 조정된다. 그러므로, 지지대(24)에 대해 수직요동된 상태에서 암(26)을 유지하는 마찰 메커니즘(34)이 제공된다.
마찰 메커니즘(34)은 위의 구조에 제한되지 않고, 임의의 다양한 구조일 수 있다. 본 실시예에서, 마찰 메커니즘(34)의 수 나사 부재(2408), 브래켓(2404, 2406), 및 평판 부재(2602)는 또한 수직요동 메커니즘(33)의 컴포넌트로서도 역할을 한다.
사용자가 암(26) 또는 디스플레이 장치(12)를 쥐고 디스플레이 장치(12)가 지지대(24)에 대해 원하는 위치에 오도록 회전하여, 암(26) 또는 디스플레이 장치(12)를 릴리스할 때, 지지대(24)에 대한 암(26)의 각도는, 토션 코일 스프링(32), 평행추(28), 및 마찰 메커니즘(34)에 의해 유지된다.
도 6은 디스플레이 장치(12)의 평면도이고, 도 7은 수직요동 메커니즘(36)의 단면도이다.

도 9는 오디오 신호 처리 회로(4008)를 상세한 블럭도로 나타낸다.
도 9에 도시된 것처럼, 오디오 신호 처리 회로(4008)는, 마이크로컴퓨터(56), A/D 변환기(58), 신호 처리 블럭(60), 2개의 D/A 변환기(62H, 62L), 및 2 개의 증폭기(64H, 64L)를 포함한다.
마이크로컴퓨터(56)는, 거리 검출기(54)로부터 공급되는 검출된 거리 신호와, 타이밍 제어기(4202)로부터 공급되는 제어 신호를 기초로 지연 제어 회로를 발생시킨다.
A/D 변환기(58)는, 스위칭 회로(4004)로부터 공급되는 좌측과 우측 채널 아날로그 오디오 신호를 디지털 신호로 변환한다
신호 처리 블럭(60)은 지연 조정기(6002)와 톤 교정기(6004)를 포함한다.
톤 교정기(6004)는, A/D 변환기(58)로부터 공급되는 오디오 신호를, 중저 주파수 범위의 오디오 신호와 고 주파수 범위의 오디오 신호로 분리하여, 그 분리된 오디오 신호들의 출력 레벨을 증가시키거나 또는 감소시켜서, 사운드의 톤을 조정한다, 즉, 주파수 특성을 조정한다. 제어부(42)의 톤 조정 버튼이 눌러질 때, 톤 교정기(6004)는 사운드의 톤을 조정한다.
톤 교정기(6004)는 지연 조정기(6002)로 고 주파수 범위의 오디오 신호를 공급하고, D/A 변환기들(62L) 중의 하나로 중저 주파수 범위의 오디오 신호를 공급한다.
지연 조정기(6002)는, 마이크로컴퓨터(56)로부터 공급되는 지연 제어 신호에 기초하여 결정되는 지연 시간에 의해 톤 교정기(6004)로부터 공급되는 고 주파수 범위의 오디오 신호를 지연시키고, 다른 D/A 변환기(62H)로 지연된 오디오 신호를 공급한다.
지연 조정기(6002)는 예를 들어, RAM(6002A)과, RAM(6002A)으로(부터) 데이 터의 읽기/쓰기를 제어하는 제어기(6002B)를 포함한다. 제어기(6002B)가 RAM(6002A)에 고 주파수 범위의 오디오 신호의 데이터를 기록한 후, 제어기(6002B)는 RAM(6002A)으로부터 데이터를 읽어서 고 주파수 범위의 오디오 신호를 지연 시간만큼 지연시킨다.
D/A 변환기(62H)는 지연 조정기(6002)로부터 공급되는 고 주파수 범위의 디지털 오디오 신호(본 실시예에서, 제1 오디오 신호)를 아날로그 오디오 신호로 변환하고, 증폭기(64H) 중의 하나로 그 아날로그 오디오 신호를 공급한다.
D/A 변환기(62L)는 톤 교정기(6004)로부터 공급되는 중저 주파수 범위의 디지털 오디오 신호(본 실시예에서, 제2 오디오 신호)를 아날로그 오디오 신호로 변환하고, 아날로그 오디오 신호를 다른 증폭기(64L)로 공급한다.
증폭기(64H)는 D/A 변환기(62H)로부터 공급되는 고 주파수 범위의 오디오 신호를 증폭하고, 그 증폭된 오디오 신호를 제1 스피커(50), 즉, 스피커부(50A, 50B)로 공급한다.
증폭기(64L)는 D/A 변환기(62L)로부터 공급되는 중저 주파수 범위의 오디오 신호를 증폭시키고, 그 증폭된 오디오 신호를 제2 스피커(52), 즉, 스피커부(52A, 52B)로 공급한다.
그러므로, 제1 스피커(50)로부터 사운드 출력의 타이밍은 지연 시간만큼 제2 스피커(52)로부터 사운드 출력의 타이밍을 늦춘다.
오디오 신호 처리 회로(4008)는 제1 스피커(50)와 제2 스피커(52)로 오디오 신호를 공급하는 신호 공급부를 포함한다.
오디오 신호 처리 회로(4008)는 또한, 신호 공급부로부터 출력되는 고 주파수 범위의 오디오 신호(제1 오디오 신호)의 타이밍과, 신호 공급부로부터 출력되는 중저 주파수 범위의 오디오 신호(제2 오디오 신호)의 타이밍 사이의 시간 차이를 조정하기 위한 신호 처리기를 제공한다.
텔레비전 장치(10)의 동작과 이점은 아래 설명될 것이다.
도 10은, 텔레비전 장치(10)의 제1과 제2 스피커(50, 52)로부터 출력되는 사운드와 사용자 P 사이의 관계를 개략적으로 나타낸다.
도 10에 도시된 것처럼, 디스플레이 장치(12)는 베이스(22)의 앞으로 크게 당겨진다.
이 시점에서, 디스플레이 장치(1202)의 앞에 위치된 사용자 P의 귀로부터 제2 스피커(52)로의 거리 L2는, 사용자 P의 귀로부터 제1 스피커(50)로의 거리 L1보다 거리(L2 - L1)만큼 더 크다.
그러므로, 제2 스피커(52)로부터 출력된 중저 주파수 범위의 사운드가 사용자 P의 귀에 도달하는 것보다, 제1 스피커(50)로부터 출력된 고 주파수 범위의 사운드가 사용자 P의 귀에 더 일찍 도달한다.
고 주파수 범위의 사운드가 사용자 P의 귀에 도달하는 시간과, 중저 주파수 범위의 사운드가 사용자 P의 귀에 도달하는 시간 사이의 시간 차이 △t는 다음과 같이 표현된다:
△t = (L2 - L1)/Vs
여기서, Vs는 사운드 속도를 나타낸다.
시간 차이 △t의 크기에 따라, 사용자 P는 그가 듣는 사운드에 대해 불편하고 부자연스럽다고 느낄 것이다.
본 실시예에 따르면, 거리 검출기(54)는 제1과 제2 스피커(50, 52) 사이의 거리 △L을 (L2 - L1)으로서 검출한다. 고 주파수 범위의 사운드의 타이밍은 사운드가 거리 △L를 이동하는 데 필요한 시간만큼 지연되고, 그 고 주파수 범위의 지연은 제1 스피커(50)로부터 출력된다.
더 구체적으로, 마이크로컴퓨터(56)는 시간 차이 △t를 제거하는 지연 제어 신호를 발생시키고, 발생된 지연 제어 신호를 지연 조정기(6002)로 공급한다. 달리 설명하면, 마이크로컴퓨터(56)는 고 주파수 범위의 사운드를 조정하여, 제1 스피커(50)로부터의 사운드 출력과 제2 스피커(52)로부터의 사운드 출력이 텔레비전 장치(10)의 앞쪽 위치, 즉, 사용자 P의 귀에 같은 시간에 도달한다.
결과적으로, 사용자 P가 시간 차이 △t로 인해 불편하거나 또는 부자연스럽게 느끼는 것이 방지되고, 좋은 톤의 사운드를 들을 수 있다.
엄격히 말하면, 제1과 제2 스피커(50, 52) 사이의 거리 △L와 그 차이(L2 - L1)는 서로 같지 않다. 그러나, 실제 사용에서, 사용자 P와 텔레비전 장치(10) 사이의 위치 관계와 거리의 관점에서, 제1과 제2 스피커(50, 52) 사이의 거리 △L과 차이 (L2 - L1) 사이의 차이가 사운드 타이밍의 조정에 갖는 임의의 효과는 무시할 만하다.
이 분야에서, 인간 청각 특성에 따르면, 고 주파수 범위의 사운드가 중저 주파수 범위의 사운드보다 더 일찍 들리고, 만약 고 주파수 범위의 사운드가 중저 주 파수 범위의 사운드보다 더 늦게 들리면, 사운드는 온화하게(부드럽게) 인지됨이 알려졌다.
그러므로, 고 주파수 범위의 사운드가 너무 크게 들리면, 고 주파수 범위의 사운드가 중저 주파수 범위의 사운드보다 더 늦게 들리도록 사운드를 조정하는 것이 바람직하다. 환언하면, 사운드가 불명료하게 들리면, 고 주파수 범위의 사운드가 중저 주파수 범위의 사운드보다 더 일찍 들리도록 사운드를 조정하는 것이 바람직하다.
본 실시예에 따르면, 타이밍 제어기(4202)에 의해 발생되는 제어 신호가 마이크로컴퓨터(56)에 공급될 때, 마이크로컴퓨터(56)는 지연 조정기(6002)에 지연 제어 신호를 공급하여, 제2 스피커(52)로부터의 중저 주파수 범위 출력의 사운드 타이밍에 대해 제1 스피커(50)로부터의 고 주파수 범위 출력의 사운드 타이밍을 앞당기거나 또는 지연시켜서, 사운드의 명료성 또는 부드러움을 자유롭게 조정한다. 결과적으로, 텔레비전 장치(10)는 사용자 p의 선호에 따라 사운드를 제공할 수 있다는 이점이 있다.
일부 텔레비전 장치에서, 전체 주파수 범위는 복수의 주파수 범위로, 예를 들어, 고 주파수 범위와 저 주파수 범위로 분리되고, 각 주파수 범위의 출력 사운드 레벨이 조정된다. 그러나, 본 실시예에 따르면, 주파수 범위의 출력 사운드 레벨들 사이의 밸랜스(balance)가 전혀 변경되지 않고, 일정하게 유지되고, 사운드의 명료성 또는 부드러움이 자유롭게 조정된다. 결과적으로, 텔레비전 장치(10)는 사용자에게 양질의 사운드를 제공할 수 있다는 이점이 있다.
본 실시예에 따르면, 또한, 마이크로컴퓨터(56)로부터 지연 조정기(6002)로 공급되는 지연 제어 신호는, 거리 검출기(54)로부터 공급되는 검출된 거리 신호에 따른 거리 △L에 따라 발생되는 지연 제어 신호와, 타이밍 제어기(4202)로부터 공급되는 제어 신호에 따라 발생되는 지연 제어 신호에 기초된다.
그러므로, 사운드 명료성 또는 부드러움이 타이밍 제어기(4202)에 의해 원하는 레벨로 조정된 후, 디스플레이 장치(12)가 앞으로 또는 뒤로 이동되어도, 거리 검출기(54)가 거리 △L의 변경을 검출하고 마이크로컴퓨터(56)가 거리 △L의 검출된 변경에 따른 지연 제어 신호를 조정하므로, 사운드 명료성 또는 부드러움은, 디스플레이 장치(12)가 앞으로 또는 뒤로 이동하기 전에 얻었던 레벨을 유지한다. 결과적으로, 디스플레이 장치(12)가 앞 또는 뒤 방향으로 그것의 위치를 변경할 때도, 타이밍 제어기(4202)는 다시 조정될 필요가 없다. 그러므로, 텔레비전 장치(10)는 단순하게 동작되고 사용하기 용이하다는 이점이 있다.
달리 설명하면, 타이밍 제어기(4202)는 시간 차이를 설정하고, 제1 스피커(50)로부터의 사운드 출력과 제2 스피커(52)로부터의 사운드 출력은 텔레비전 장치(10) 앞의 사용자 P에 특정 시간 차이로 도달한다. 이 시점에서, 거리 검출기(54)가 제1 스피커(50)와 제2 스피커(52) 사이의 거리 △L = (L2 - L1)의 변경을 검출하면, 오디오 신호 처리 회로(4008)(신호 처리기)는, 제1 스피커(50)로부터의 사운드 출력과 제2 스피커(52)로부터의 사운드 출력이 사용자 P에게 특정 시간 차이로 도달하도록, 시간 차이를 조정한다.
제2 실시예:
본 발명의 제2 실시예에 따른 텔레비전 장치가 아래 설명될 것이다.
제2 실시예에 따른 텔레비전 장치는, 거리 검출기가 종래 기술의 각도 센서를 포함한다는 점에서 제1 실시예에 따른 텔레비전 장치와는 상이하고, 다른 세부사항들에서는 제1 실시예에 따른 텔레비전 장치와 동일하다.
도 11은 각각의 각도 센서(5410, 5412)에 의해 검출되는 각도 θ1, θ2를 개략적으로 나타내고, 도 12는 검출된 각도 θ1, θ2에 기초하여 제1과 제2 스피커(50, 52) 사이의 거리 △L의 계산을 개략적으로 나타낸다.
제1 실시예에 따른 텔레비전 장치의 것들과 동일한 제2 실시예에 따른 텔레비전 장치의 부분들은 동일한 참조 부호로 표시된다.
도 11에 도시된 바와 같이, 제2 실시예에 따른 텔레비전 장치(10)는 제1 각도 센서(5410)와 제2 각도 센서(5412)를 갖는다.
암(26)과 수평 축 사이에 형성된 각도 θ1를 검출하기 위해, 지지대(24)와 암(26) 사이의 접합부에 제1 각도 센서(5410)가 배치된다.
각도 θ1이 수평 축 위에 존재하면, 그것은 양의 값을 갖고, 각도 θ1이 수평 축 아래 존재하면, 그것은 음의 값을 갖는다.
지지대(24)와 수직 축 사이에 형성된 각도 θ2를 검출하기 위해, 베이스(22)의 프레임과 지지체(30) 사이의 접합부에 제2 각도 센서(5412)가 배치된다.
각도 θ2가 수직 축의 좌측에 존재하면, 그것은 양의 값을 갖고, 각도 θ2가 수직 축의 우측에 존재하면, 그것은 음의 값을 갖는다.
검출된 각도 θ1, θ2를 나타내는 각도 센서(5410, 5412)에 의해 발생되는 검출된 각도 신호는 마이크로컴퓨터(56)(도 9 참조)에 공급된다.
도 12에 도시된 바와 같이, 수평 축이 좌표 시스템의 X-축으로서 주어지고, 수직 축이 좌표 시스템의 Y-축으로서 주어지고, 프레임과 지지체(30) 사이의 접합점은 좌표 시스템의 원점 P0(0, 0)에 좌표를 갖고, 암(26)과 디스플레이 장치(12) 사이의 접합점(수직요동 메커니즘(36))은 제1 좌표 P1(x1, y1)을 갖고, 암(26)과 지지대(24) 사이의 접합점(마찰 메커니즘(34))은 제2 좌표 P2(x2, y2)를 갖고, 제1 좌표 P1(x1, y1)로부터 제2 좌표 P2(x2, y2)로의 거리는 LA1으로 표현되고, 제2 좌표 P2(x2, y2)로부터 원점까지의 거리는 LA2로 표현된다고 가정된다.
제1 좌표 P1(x1, y1)은 다음 수학식 1로 표현된다:
Figure 112007018745624-PAT00001
본 실시예에 따르면, 제1 좌표 P1(x1, y1)는 제1 스피커(50) 가까이 위치되고, 원점(0, 0)은 제2 스피커(52) 가까이에 위치된다.
그러므로, 원점으로부터 제1 좌표 P1(x1, y1)까지의 거리, 즉, 제1 스피커와 제2 스피커(50, 52) 사이의 거리 △L = Lpanel은, 수학식 1에 따른 제1 좌표 P1(x1, y1)를 사용하여, 다음 수학식 2로 표현된다:
Figure 112007018745624-PAT00002
수학식 1과 2에 기초하여, 마이크로컴퓨터(56)는 제1과 제2 스피커(50, 52) 사이의 거리 △L를 계산한다.
본 발명의 본 실시예에 따르면, 거리 검출기는 제1 각도 센서(5410), 제2 각도 센서(5412), 및 마이크로컴퓨터(56)를 포함한다.
다른 컴포넌트들은 제1 실시예에서 언급된 것과 동일하다.
제2 실시예에 따른 텔레비전 장치는 제1 실시예에 따른 텔레비전 장치의 것들과 동일한 이점을 제공한다. 제1 실시예에 따르면, 적외선 또는 초음파 거리 검출기는 이들의 송신기와 수신기를 노출시켜 볼 수 있도록 할 필요가 있다. 그러나, 제2 실시예에 따르면, 제1 각도 센서(5410)와 제2 각도 센서(5412)가 비노출 위치에 배치될 수 있으므로, 제2 실시예에 따른 텔레비전 장치(10)는 더 나은 외관을 갖는다.

설명된 실시예들에서, 제1 스피커(50)로부터의 사운드 출력의 주파수 범위는 제2 스피커(52)로부터의 사운드 출력의 주파수 범위보다 더 높다. 본 발명은 또한 텔레비전 장치에도 적용가능하고, 제1과 제2 스피커(50, 52)는 동일한 주파수 범위 를 갖는다.
제1과 제2 스피커(50, 52)가 동일한 주파수 범위를 가져도, 텔레비전 장치는, 스피커들 중의 하나로부터 사용자 P에 도달하는 사운드 출력의 타이밍과, 다른 스피커로부터 사용자 P에 도달하는 사운드 출력의 타이밍을 조정하여 사운드의 양질을 제공할 수 있다.
제1과 제2 스피커(50, 52)가 동일한 주파수 범위를 가져도, 텔레비전 장치는, 스피커들 중의 하나로부터 사용자 P에 도달하는 사운드 출력의 타이밍과 다른 스피커로부터 사용자 P에 도달하는 사운드 출력의 타이밍 사이의 시간 차이를 조정하여 톤 조정을 할 수 있다.
설명된 실시예에서, 제1 스피커(50)는 디스플레이 장치(12) 상에 장착되고, 제2 스피커(52)는 베이스(22) 상에 장착된다. 그러나, 제1과 제2 스피커(50, 52)가 서로로부터 분리되어 있는 한, 제1과 제2 스피커(50, 52) 중의 하나 또는 모두는 디스플레이 장치(12) 또는 베이스(22)로부터 분리될 수 있다.
본 발명의 특정하게 선호되는 실시예들이 상세히 도시되고 기재되었지만, 첨부된 청구범위의 범위를 벗어나지 않고 다양한 변경과 수정이 만들어질 수 있슴을 이해해야 한다.
본 발명에 따르면, 제1 스피커로부터 출력된 오디오 신호와, 제2 스피커로부터 출력된 오디오 신호를 사용자의 귀에 동일한 타이밍으로 전달시킬 수 있으므로, 사용자가 오디오 신호로부터 불편함이나 부자연스러움을 느끼게 하는 것을 방지할 수 있어서 양호한 음질의 오디오 신호를 제공할 수 있다.
