由于现代汽车电器的飞速发展,汽车上除有低压报警器外,有些车上还增添了转向蜂鸣器.但由于此电器在我国还未大量生产,经常供不应求.笔者设计了一种不需添置任何设备,只需加接一根导线,即可让低压报警器(一般解放牌车已装此电器)兼作转向蜂鸣器用(但必须是负极搭铁车型).方法是在低压报警器的负极线上再引出一根线,接到闪光继电器标有“开关”的接柱上即可(见右图). Due to the rapid development of modern automotive electronics, in addition to the car on the low-pressure alarm, some cars also added a steering buzzer, but because of this appliance has not yet been mass-produced in our country, often in short supply. I designed a need to purchase Any device, just add a wire, you can let the low-voltage alarm (the general liberation of the car has been installed with this device) also serves as a steering buzzer (but must be a negative pole on the car.) Method is in the low-voltage alarm negative The line leads to a line, connected to the flash relay labeled “switch” on the post (see right).
