Structure of vibration sensor
First Claim
1. A base, an electrically conductive hopper, a spring in the form of a winding extending between said hopper and said base and supporting said hopper over said base, an electrically conducting element extending into said hopper without touching said hopper when said spring is in an equilibrium position at rest, said winding of said spring having its greatest diameter at a middle point of said spring between said hopper and said base and decreasing in diameter proceeding from said middle point toward said hopper and said base, said winding having its least density at said middle point and increasing in density proceeding from said middle point to said hopper and said base.

Abstract
A new structure of vibration sensor mainly comprising two metal conducting plates on its body, one of which is installed with an adjusting screw and the other with a fixing screw connecting to a vibrating spring which is connected to a hopper conductor at the other end. The adjusting screw is located in such a manner that its tip is in the middle of the hopper conductor, so that when the vibrating spring detects shock signals it causes contact between the hopper conductor and the adjusting screw.
