Finger ring for performing a magic act
View Patent ↗A ring for performing magic tricks is provided that has a miniaturized vibration motor, an on/off switch, a power supply element, a metallic contact blade, on which the power supply element is positioned, and a printed circuit board which receives wiring to interconnect the battery and the motor on the other, thereby closing the circuit.
1. A finger ring for performing a magic act, the finger ring comprising:
an annular body with an upper portion that forms a flat and recessed top face and a lower portion that has a first cavity and a second cavity disposed on an inner circumference thereof;
a power supply element and at least four magnet elements disposed in the flat and recessed top face;
a metal plate covering the flat and recessed top face and attached to the at least four magnet elements;
a vibration motor disposed in the first cavity;
a printed circuit board disposed in the second cavity and operable by a switch having an on/off button;
a first contact element in electrical communication with the power supply element and the printed circuit board; and
a second contact element in electrical communication with the vibration motor and the printed circuit board.
2. The finger ring according to claim 1 , further comprising: a stone disposed over the metal plate.
3. The finger ring according to claim 1 , wherein the at least four magnet elements are Neodymium magnets.
4. The finger ring according to claim 1 , wherein the second cavity has an opening through the annular body to an outer surface thereof and the switch is disposed in the second cavity so that the on/off button projects from the outer surface of the annular body through the opening.
5. The finger ring according to claim 1 , wherein the power supply element is a battery.
6. The finger ring according to claim 5 , wherein the battery is a rechargeable lithium battery.
7. The finger ring according to claim 6 , further comprising a recharging circuit board disposed in a third cavity on the inner circumference of the annular body, and wherein the printed circuit board is a control circuit board that has a microcontroller and a control driver configured to reverse the vibration motor.
8. The finger ring according to claim 7 , wherein the on/off button is a touch switch.
9. The finger ring according to claim 8 , wherein the touch switch energizes the vibration motor and selects a rotation direction of the vibration motor.
10. The finger ring according to claim 7 , further comprising: a Micro USB input connected on the recharging circuit board.
11. The finger ring according to claim 7 , further comprising: an LED recharge indicator connected on the recharging circuit board.
