押しボタンスイッチの振動発生装置、押しボタンスイッチ
Document Type and Number:
Japanese Patent JP7434741
Kind Code:
B2
Abstract:
To provide a vibration generation device that can obtain a large amount of vibration without requiring feedback control of resonance frequency despite its small size, and can vibrate a movable part lifted higher than default without requiring a large thrust.SOLUTION: A vibration generation device 1 comprises: a stationary part 10 that has a bobbin 11 and a coil 12 wound around the bobbin 11; a movable part 20 that has a magnet 21 and yokes 22, 23 and is assembled to the stationary part 10 such that the magnetic flux generated by the magnet 21 is interlinked to the coil 12; and a nonlinear characteristic coil spring 30 that is arranged in coaxial hole parts 15, 24 that are formed in the bobbin 11 and the movable part 20 and have a movable direction of the movable part 20 as an axial direction, and connects the stationary part 10 with the movable part 20.SELECTED DRAWING: Figure 2
