ABSTRACT:
Disclosed herein is a vibration generation module capable of generating inertial and impact vibrations. The vibration generation module includes a magnetic force generation unit, an elastic force provision unit, a permanent magnet, a contactor, and an impact transmission panel. The permanent magnet is configured such that when periodic electrical energy having a specific duty or voltage is supplied to the magnetic force generation unit, the permanent magnet alternates between a position in which the permanent magnet is completely spaced apart from the magnetic force generation unit and a completely lowered position in which the permanent magnet collides with an upper surface of the magnetic force generation unit, and such that periodic electrical energy having another specific duty or voltage is supplied to the magnetic force generation unit, the permanent magnet alternates between a position in which the permanent magnet is partially spaced apart from the magnetic force generation unit and a partially lowered position in which the permanent magnet is close to the upper surface of the magnetic force generation unit.
