Abstract

A vibration sensor includes casing, substrate, and elastic metal piece; two electrode areas separated by a separation zone being provided on the substrate; a vibration contact being provided on the separation zone; placement being executed by the metal piece on the substrate to contact or not to contact both electrode areas and produce connection or disconnection at the vibration contacts for selecting to turn on or off a power source and an electronic device connected to the vibration sensor and producing intermittent conduction by means of the sensor built in an object.

Claims

1. A vibration sensor built in an object includes the object containing a chamber to accommodate the vibration sensor;

the vibration sensor includes a casing, a substrate, an elastic metal piece, and a transmission contact;

the casing having one side disposed with an opening and screened by means of a substrate and containing an accommodation space;

a separation zone being provided on the substrate to segregate two electrode areas, a vibration contact separated from both electrode areas being disposed on the separation zone, and either electrode area being disposed with the transmission contact;

the elastic metal piece contained in the accommodation space of the vibration sensor to engage in displacement to simultaneously contact or not to contact both electrode areas, and causing the vibration contact to be conducted through or disconnected; and

the transmission contact being connected to a power source, the substrate, and an electronic device to selectively transmit the power from the power source to the electronic device through the substrate while enabling the electronic device to produce intermittent conduction.

2. A vibration sensor of claim 1, wherein the elastic metal piece includes a load, an outer coil, and an inner coil;

the load includes a column and a flange protruding from the column, and a nipple to contact the substrate being disposed on the distal side to the flange of the column.

3. A vibration sensor of claim 2, wherein the inner diameter of the outer coil is slightly greater than the diameter of the flange for the outer coil to be merely inserted onto the outer side of the flange.

4. A vibration sensor of claim 2, wherein the length of the outer coil is slightly greater than the height of the accommodation space.

5. A vibration sensor of claim 2, wherein the inner diameter of the inner coil is slightly greater than the diameter of the column for the inner coil to be merely inserted onto the outer side of the column of the load.

6. A vibration sensor of claim 1, wherein the object is related to apparel or a flashlight.

7. A vibration sensor of claim 6, wherein the flashlight is built in a shoe, a chamber is formed in the tongue of the shoe to accommodate the flashlight, and each electronic device disposed in the sole of the shoe is connected to the flashlight by means of a conductor.

8. A vibration sensor of claim 1, wherein the substrate is related to a circuit board.

9. A vibration sensor of claim 1, wherein multiple holes are disposed on the substrate for the transmission contact, multiple conductive posts in the same number as that of the holes receive insertion of their corresponding conductive posts;

and the circuit is connected among those conductive posts, the power source, and the electronic device.

10. A vibration sensor of claim 1, wherein the power source relates to a cell.

11. A vibration sensor of claim 1, wherein the electronic device is related to a light source or a loudspeaker.

12. A vibration sensor of claim 11, wherein the light source is comprised of one or a plurality of single color or multiple-color light emitting diode.

13. A vibration sensor of claim 1, wherein a SW indication is provided on the outer side of the casing to mark the conductive direction of the power source.
