The invention provides a vibration device which comprises a base, a guide shaft, a vibration head and induction magnetic steel, the lower end of the base is provided with an accommodating cavity, the upper end of the base is provided with a coil winding and a Hall element, the guide shaft is in sliding fit with the base, one end of the guide shaft is fixedly connected with the vibration head, and the other end of the guide shaft is fixedly connected with the induction magnetic steel. And after the Hall element is electrically connected with the coil winding in series, the two ends of the Hall element are connected to a power supply. By adopting the technical scheme, after the power supply is switched on, the guide shaft and the vibration head are driven to move downwards under the action of magnetic force generated by the coil winding, so that the distance between the Hall element at the upper end of the guide shaft and the induction magnetic steel is gradually increased, the power supply of the coil winding is finally cut off, and the power supply is switched on after the guide shaft and the vibration head are forced to move upwards again; the vibration head has the advantages of being compact in structure, small in size, light in weight, convenient to install, high in reliability and long in service life.
本发明提供一种振动装置,包括底座、导轴、振动头和感应磁钢,底座下端设有容纳腔,底座上端设置有线圈绕组和霍尔元件,导轴与底座滑动配合,导轴的一端与振动头固连,导轴的另一端与感应磁钢固连,并且感应磁钢与霍尔元件彼此相对对置,霍尔元件与线圈绕组电性串联连接后再将其两端接入电源。采用本发明的技术方案,当接通电源后,在线圈绕组产生磁力作用下驱使导轴和振动头向下运动,使导轴上端的霍尔元件与感应磁钢之间的间距逐渐增大,并最终切断线圈绕组的电源,迫使导轴和振动头重新向上运动后又接通电源,实现了振动头上下往复振动,具有结构紧凑,体积小,重量轻,便于安装,可靠性高,使用寿命长的优点。
