Disclosed are an apparatus and a method to adjust a burglar alarm sound for a vehicle, capable of simply adjusting a level of an alarm pressure through a sound level adjustment switch installed outside without modifying a structure, a sound source, a circuit, a logic, etc. of an alarm sound generation unit to output the alarm sound in burglary of the vehicle. According to the present invention, the apparatus comprises: the sound pressure adjustment switch installed outside the apparatus and selecting an output level to adjust the sound level of the alarm sound; a control unit determining a pulse wave modulation (PWM) duty ratio in accordance with the output level selected by the sound pressure adjustment switch and generating a PWM signal in accordance with the determined PWM duty ratio to apply the PWM signal to a boosting adjustment unit; the boosting adjustment unit boosting or lowering operation voltage of the alarm sound output unit in accordance with the PWM signal to vary the operation voltage; and an alarm sound output unit generating the alarm sound in accordance with the boosted or lowered operation voltage to output the alarm sound as an audible sound. According to the present invention, the apparatus can be used in common irrespective of vehicle model and a mounting position in accordance with the level of the alarm sound is also not restricted.

    본 발명은 차량 도난 시에 경보음을 출력하는 경보음 발생부의 구조, 음원, 회로, 로직 등의 변경 없이 외부에 구비된 음압 조절 스위치를 통해 간단히 경보음 레벨을 조정할 수 있도록 하는 장치 및 방법이 개시된다. 개시된 차량용 도난 경보음 레벨 조장 장치는, 장치의 외부에 구비되고, 경보음의 음압을 조절하기 위해 출력 레벨을 선택하는 음압 조절 스위치; 상기 음압 조절 스위치에 의해 선택된 출력 레벨에 따라 PWM 듀티비를 결정하고, 결정된 PWM 듀티비에 따라 PWM 신호를 생성하여 승압 조절부에 인가하는 제어부; 상기 PWM 신호에 따라 경보음 출력부의 동작 전압을 승압 또는 하강시켜 가변시키는 승압 조절부; 및 상기 승압 또는 하강된 동작 전압에 따라 경보음을 생성하여 가청음으로 출력하는 경보음 출력부를 포함한다. 본 발명에 의하면, 차종에 관계 없이 공용화 할 수 있고, 경보음 레벨에 따른 장착 위치의 제약도 받지 않도록 할 수 있다.
