본 고안은 헤드폰 스테레오 장치에서 외부 충격에 의해 데크 및 제어 회로의 오동작을 방지하기 위한 헤드폰 스테레오 외부 충격 감지 및 제어회로에 관한 것이다.The present invention relates to a headphone stereo external shock detection and control circuit for preventing malfunction of the deck and the control circuit by an external shock in the headphone stereo device.
헤드폰 스테레오 장치는 일반적으로 휴대형이기 때문에 외부 충격을 쉽게 받게 된다. 외부 충격은 세트가 구동하지 않는 경우에는 그 충격이 대단히 크지 않는 한 큰 문제로 나타나지 않게 되지만, 세트 구동시 외부 충격을 받게되면 데크나 세트 제어회로에 무리가 가서 오동작을 유발하게 된다.Headphone stereo devices are generally portable, so they are easily subject to external shocks. The external shock does not appear as a big problem unless the impact is very large when the set is not driven, but if an external shock is received during the set driving, the deck or the set control circuit may be overwhelmed and cause a malfunction.
본 고안은 외부 충격에 의해 동작중인 헤드폰 스톄레오가 받게 될 위험 요소를 사전에 배제시킬 수 있는 헤드폰 스테레오 외부 충격 감지 및 제어회로를 제공하는데 그 목적이 있다.It is an object of the present invention to provide a headphone stereo external shock detection and control circuit that can preemptively remove a risk that a headphone stereo is in operation by an external shock.
이하 첨부한 도면을 참고로하여 본 고안을 설명하면 다음과 같다.Hereinafter, the present invention will be described with reference to the accompanying drawings.
제1도는 헤드폰 스테레오 장치에서 외부 충격을 감지하기 위한 압전센서(11-14)의 설치 위치를 보이고 있다. 상기 압전 센서(11-14)는 헤드폰 스테레오 본체(10)의 4모서리 부위에 설치하는 것이 충격 감지에 가장 효율적 이다.FIG. 1 shows an installation position of the piezoelectric sensor 11-14 for detecting an external shock in a headphone stereo device. The piezoelectric sensors 11-14 may be installed at four corners of the headphone stereo main body 10 to be most effective for shock detection.
제2도는 상기 압전센서로부터 얻어진 감지신호를 처리하는 제어회로 구성도로써, 압전센서(11-14)에서 발생되는 전기적 신호는 모두 오어게이트(16)로 오어링되어 마이콤(17)의 인터럽트 단자(INT)로 입력되게 연결하고, 상기 마이콤(17)은 인터럽트 단자(INT)의 입력신호에 기조하여 스톱단자(STOP)에서 데크 제어부(18)로 스톱 로직 신호를 출력하게 연결하여 구성한다.2 is a control circuit diagram for processing the detection signal obtained from the piezoelectric sensor, all electrical signals generated from the piezoelectric sensor 11-14 are ordered to the orifice 16, the interrupt terminal of the microcomputer 17 ( INT), and the microcomputer 17 is configured to connect a stop logic signal from the stop terminal STOP to the deck controller 18 based on the input signal of the interrupt terminal INT.
이와같이 구성된 본 고안의 작용 및 효과를 설명하면 다음과 같다.Referring to the operation and effects of the present invention configured as described above are as follows.
헤드폰 스테레오 장치가 외부 충격을 받으면 충격을 받는 쪽의 압전센서에서 전기적 신호가 발생된다.When the headphone stereo device receives an external shock, an electrical signal is generated by the piezoelectric sensor on the shocked side.
이러한 전기적 신호는 4개의 압전센서(11-14)중 1개이상의 압전센서에서 나타나게 되며, 오어 게이트 (16)에서 오어링된다. 따라서 몇개의 어느쪽 압전센서에서 전기적 신호가 발생되는가를 불문하고 충격이 감지되기만하면 마이콤(17)의 인터럽트 단자(INT)에는 하이레벨 로직 신호가 입력된다.This electrical signal appears in one or more piezoelectric sensors of the four piezoelectric sensors 11-14 and is ored at the or gate 16. Accordingly, a high level logic signal is input to the interrupt terminal INT of the microcomputer 17 as long as a shock is detected regardless of which piezoelectric sensor is generated.
이때 마이콤(17)은 외부 충격이 있음을 인식하고 데크 제어부(18)에 데크스톱신호를 출력하여 헤드폰 스테레오의 파워 공급을 차단한다.At this time, the microcomputer 17 recognizes that there is an external shock and outputs a deck stop signal to the deck controller 18 to cut off the power supply of the headphone stereo.
따라서 본 고안은 외부 충격시 신속하게 세트 파워를 차단함으로써, 충격을 받은 상태에서 더이상 데크등이 동작되지 않게 하여 데크나 제어회로가 입을 손상을 사전에 예방할 수 있게 된다.Therefore, the present invention is to quickly cut off the set power during an external shock, so that the deck or the like no longer operates in the shocked state to prevent damage to the deck or the control circuit in advance.
