The circuit element includes a circuit board and a circuit control element. The light emitting diodes are mounted on and electrically connected to the circuit board. The power supplies electrically connect with the circuit element for supplying power. The vibrating switch electrically connects to the circuit board. The transparent encapsulation body covers the circuit element, the light emitting diodes, the power supplies, and the vibrating switch. Thereby, the vibrating and twinkling device is waterproof. When the vibrating switch is vibrated, the light emitting diodes can be driven to glow and twinkle, which offers splendid effects when the stationery or textile product is used.
