    • Disclosed is a vibration motor for a portable terminal, including a flat spring; a cylindrical magnetic substance mounted on the flat spring; an annular magnetic substance disposed around the cylindrical magnetic substance mounted on the flat spring; and a coil disposed between the cylindrical magnetic substance and the annular magnetic substance, wherein the magnetic substances perform a linear reciprocal movement by the electromagnetic force generated between the magnetic substances and the coil and by the elastic force of the flat spring as an electric current is applied to the coil. The vibration motor operates at higher resonant frequencies than those of conventional vibration motors, thereby improving the sense of an after-vibration and realizing a delicate haptic feedback function.
    • 公开了一种便携式终端的振动电动机,包括平板弹簧; 安装在平板弹簧上的圆柱形磁性物质; 设置在安装在所述板簧上的所述圆筒形磁性物质周围的环状磁性物质; 以及设置在所述圆筒形磁性物质与所述环状磁性物质之间的线圈,其中,所述磁性物质通过所述磁性物质与所述线圈之间产生的电磁力和所述板簧的弹力作为电流进行线性的往复运动 应用于线圈。 振动电动机以比常规振动电动机更高的谐振频率工作,从而改善了后振动的感觉并实现了微妙的触觉反馈功能。
