The invention discloses an automobile warning tone system using an actuator to produce a sound. The system comprises a mechanical module and an electronic module, and the electronic module is powered by a 12V battery; the mechanical module comprises the actuator, and the actuator can be installed at any position of the surface of an automotive trim; and the electronic module comprises an ESD eletrostatic protection device, a power supply IC chip, a singlechip and a D-type digital input automobile-level power amplifier. The actuator is used as electromagnetic induction of a magnet and a coil for transmitting vibration in a common horn, electric energy is converted into mechanical energy, the mechanical energy is transmitted to the surface of the automotive trim for vibration and sound production, the horn and related original devices are not needed, and installation and use are more convenient; and the number of components in the whole system is reduced, the use experience in a severe environment is greatly improved, the service life is greatly prolonged, and the failure rate of the whole system can be reduced.
本发明公开了一种利用致动器发声的汽车提示音系统,包括机械模块和电子模块,所述电子模块通过12V电池供电;所述机械模块包括致动器,所述致动器可安装在汽车内饰表面的任意位置;所述电子模块包括ESD静电保护器、电源IC芯片、单片机和D类数字输入汽车级功率放大器。本发明利用致动器作为一般喇叭内部传递振动的磁铁和线圈的电磁感应,将电能转化成机械能,传递至汽车内饰表面振动并发声,不需要喇叭及相关原器件,安装与使用更加便捷;整个系统内的元器件数量减少,在恶劣环境下的使用体验、寿命得到极大提升,可以降低整个系统的故障率。
