The invention discloses a sound-level-adjustable horn and an adjusting method. In different environments, the sound level of the horn is fixed, and in some quiet environments, generated noise pollution is large, and physical and psychological health and comfort are affected. The automobile horn comprises a sensor (1) used for obtaining automobile speed signals or environment noise signals, a vehicle-mounted BCM (2) used for outputting different trigger signals, a drive circuit (3) used for adjusting the width ratio output by a horn drive circuit and controlling current flowing through a coil, the horn coil (4) and a horn diaphragm (5). The sensor is electrically connected with the vehicle-mounted BCM, the BCM is electrically connected with the drive circuit, and the drive circuit is electrically connected with the horn coil. The invention provides the sound-level-adjustable horn and the adjusting method.

    声级可调喇叭及调节方法。在不同的环境中,喇叭的声级是固定的,有些安静的环境,产生的噪音污染较大,影响身心健康和舒适性。本发明组成包括:用于获取车速信号或环境噪音信号的传感器(1),输出不同的触发信号的车载BCM(2),调整喇叭驱动电路输出的宽度比,控制流过线圈的电流的驱动电路(3),喇叭线圈(4)和喇叭膜片(5);所述的传感器与所述的车载BCM电连接,所述的BCM与所述的驱动电路电连接,所述的驱动电路与喇叭线圈电连接。本发明用于声级可调喇叭及调节方法。
