도 1은 본 고안의 바람직한 실시예에 따른 스피커출력제어장치의 블록구성도로서, 본 고안의 실시예는 이어폰(1), 키입력부(10), 튜너(12), 음성처리부(14), 증폭부(16), 잭(18), 플러그삽입검출부(20), 제어부(22), 뮤팅부(24)로 구성된다.1 is a block diagram of a speaker output control apparatus according to a preferred embodiment of the present invention, an embodiment of the present invention is an earphone 1, a key input unit 10, a tuner 12, a voice processing unit 14, amplification The part 16, the jack 18, the plug insertion detection part 20, the control part 22, and the muting part 24 are comprised.
키입력부(10)는 운전석 전방의 대시보드상에 설치되어 운전자 또는 다른 탑승객에 의해 조작되는 바, 그 키입력부(10)는 볼륨업/다운버튼, 채널선택버튼 등을 갖춘다.The key input unit 10 is installed on a dashboard in front of the driver's seat and operated by a driver or another passenger, and the key input unit 10 includes a volume up / down button, a channel selection button, and the like.
튜너(12)는 안테나(A)에 유기되는 복수의 라디오방송채널의 신호중에서 후술하는 제어부(22)의 채널선국제어신호(VT)에 의해 선택한 라디오방송채널을 선국하여 그 채널의 신호를 중간주파신호로 변환시킨 후 출력시킨다.The tuner 12 tunes a radio broadcast channel selected by the channel line international language signal V T of the control unit 22 to be described later among the signals of a plurality of radio broadcast channels transmitted to the antenna A, and intermediates the signal of the channel. Convert it to a frequency signal and output it.
음성처리부(14)는 상기 튜너(12)에서 출력되는 중간주파신호를 음성재생처리한다.The voice processor 14 performs voice reproduction on the intermediate frequency signal output from the tuner 12.
증폭부(16)는 그 음성재생부(14)에서 출력되는 음성신호를 소정레벨 증폭시킨 후에 스피커(SP1,SP2,SP3,SP4)로 인가하게 된다.The amplifier 16 amplifies a voice signal output from the voice reproducer 14 by a predetermined level and then applies it to the speakers SP1, SP2, SP3, SP4.
잭(18)은 이어폰(1)의 플러그가 삽입될 수 있도록 차량내에 설치된 스피커(SP1,SP2,SP3,SP4)의 주위에 각각 설치되는 바, 도 2에 예시적으로 나타낸 바와 같이 복수개(18a,18b...)로 이루어진다. 도 2에서는 2개를 도시하였으나 실질적으로는 스피커의 수만큼 설치된다.The jacks 18 are respectively installed around the speakers SP1, SP2, SP3, and SP4 installed in the vehicle so that the plug of the earphone 1 can be inserted. As shown in FIG. 2, a plurality of jacks 18a, 18b ...). Although two are shown in FIG. 2, they are installed as substantially as the number of speakers.
플러그삽입검출부(20)는 그 잭(18)에 이어폰(1)의 플러그가 삽입되는지를 검출하는 바, 그 플러그삽입검출부(20)는 도 3에 나타낸 바와 같이 잭(18a)내부의 저부에 고정설치된 고정단자(K) 및 이어폰(1)플러그가 삽입됨에 따라 그 고정단자(K)와 접촉되는 가동단자(L)로 구성된다.The plug insertion detection unit 20 detects whether the plug of the earphone 1 is inserted into the jack 18, and the plug insertion detection unit 20 is fixed to the bottom inside the jack 18a as shown in FIG. The fixed terminal (K) and the earphone (1) is installed as a plug is composed of a movable terminal (L) in contact with the fixed terminal (K).
제어부(22)는 그 키입력부(10)로부터의 키입력신호에 따라 카오디오시스템의 일반적인 동작을 제어하는 한편, 그 플러그삽입검출부(20)로부터의 검출신호에 의해 스피커출력을 뮤팅시킴과 더불어 음성처리부(14)에서 재생처리되는 음성신호를 이어폰(1)측으로 전달되게 제어한다.The control unit 22 controls the general operation of the car audio system according to the key input signal from the key input unit 10, while muting the speaker output by the detection signal from the plug insertion detecting unit 20. The audio signal reproduced by the processor 14 is controlled to be transmitted to the earphone 1 side.
뮤팅부(24)는 그 제어부(22)의 제어신호에 의해 음성처리부(14)에서 스피커(SP1,SP2,SP3,SP4)측으로 전달되는 음성신호를 뮤팅시키게 되는 바, 그 뮤팅부(24)는 베이스가 제어부(22)의 제어신호단에 접속되고 컬렉터가 그 음성처리부(14)의 각 출력단에 접속된 복수의 스위칭트랜지스터(Q1,Q2,Q3,Q4)로 이루어진다.The muting unit 24 mutes the voice signal transmitted from the voice processing unit 14 to the speaker SP1, SP2, SP3, SP4 by the control signal of the control unit 22, and the muting unit 24 The base consists of a plurality of switching transistors Q1, Q2, Q3, Q4 connected to the control signal terminal of the control unit 22 and the collector connected to each output end of the audio processing unit 14.
이어, 상기와 같이 구성된 본 고안의 실시예에 따른 스피커출력제어장치의 동작에 대해 설명하면 다음과 같다.Next, the operation of the speaker output control apparatus according to the embodiment of the present invention configured as described above is as follows.
일단, 키입력부(10)로부터의 카오디오시스템동작신호가 입력된 후 임의의 채널이 선택되면 그 선택된 채널의 라디오방송신호가 음성재생되어 스피커(SP1,SP2, SP3,SP4)출력된다.Once a certain channel is selected after the car audio system operation signal from the key input unit 10 is input, the radio broadcast signal of the selected channel is reproduced as voice and output to the speakers SP1, SP2, SP3, SP4.
이와 같이 임의의 채널의 음성이 출력되고 있는 상태에서, 내부탑승객중에서 어느 한 사람이 스피커(SP1)부근에 설치된 잭(18a; 도 4참조)에 이어폰(1)플러그를 삽입시켰다고 설정한 경우 그 플러그삽입에 따른 가동단자(L)와 고정단자(K)와의 접촉신호가 제어부(22)로 인가되므로, 그 제어부(22)는 현재 이어폰(1)플러그가 삽입된 것으로 인식하고서 뮤팅부(24)를 구성하는 복수의 스위칭트랜지스터(Q1,Q2,Q3,Q4)를 도통시켜 현재 음성처리부(14)에서 출력되는 음성신호를 뮤팅시키는 한편, 음성처리부(14)를 제어하여 현재 재생처리되는 음성신호를 이어폰(1)측으로 전달시키게 된다.In the state where the audio of any channel is output in this way, when one of the internal passengers sets the plug of the earphone 1 into the jack 18a (see Fig. 4) installed near the speaker SP1, the plug is set. Since the contact signal between the movable terminal L and the fixed terminal K according to the insertion is applied to the control unit 22, the control unit 22 recognizes that the earphone 1 plug is currently inserted and recognizes the muting unit 24. The plurality of switching transistors Q1, Q2, Q3, and Q4 are configured to conduct electricity to mute the voice signal currently output from the voice processor 14, and the voice processor 14 is controlled to control the voice signal currently reproduced. It is delivered to (1) side.
따라서, 그 이어폰(1)을 삽입시킨 탑승객만이 현재 선택된 라디오채널의 음성을 청취할 수 있게 되는 것이다.Therefore, only the passenger who inserted the earphone 1 can listen to the voice of the currently selected radio channel.
이상 설명한 바와 같은 본 고안에 의하면, 스피커출력음을 선택적으로 청취할 수 있게 되므로, 주위사람의 수면을 방해하지 않을 뿐만 아니라 청취를 거부하는 탑승객의 기분을 거스리지 않게 된다.According to the present invention as described above, it is possible to selectively listen to the speaker output sound, not only do not disturb the sleep of the people around, but also does not disturb the passengers refusing to listen.
