Vibration generation module capable of generating inertial and impact vibrations
First Claim
1. A vibration generation module capable of generating inertial and impact vibrations, comprising:
- a magnetic force generation unit made of magnetic material to generate magnetic force when electrical energy is supplied from an external source;
an elastic force provision unit fixedly mounted above the magnetic force generation unit, and configured to provide elastic force in a vertical direction;
a permanent magnet coupled to the elastic force provision unit, and configured such that when electrical energy is not supplied to the magnetic force generation unit, the permanent magnet is lowered to a position in contact with or near an upper surface of the magnetic force generation unit by its own magnetic force, so that the elastic force provision unit enters a state of holding elastic restoring force, such that when periodic electrical energy having a duty or voltage higher than a reference value 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, thereby generating impact vibrations, and such that periodic electrical energy having a duty or voltage lower than a reference value 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, thereby generating inertial vibrations;
a contactor fastened to one side of the permanent magnet, and configured to be selectively raised and lowered as the permanent magnet is moved; and
an impact transmission panel configured to collide with a front end of the contactor and generate impact when the permanent magnet is moved to the completely raised position.

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.
