Abstract

The invention provides a driving circuit for a vehicle-mounted sound-control flashing humidifier. The driving circuit comprises a voltage conversion unit, a sound control unit, a light emitting diode, a piezoelectric ceramic piece, wherein a positive electrode access end of the voltage conversion circuit is connected with a positive electrode of a power socket, and a negative electrode access end of the voltage conversion circuit is connected with a negative electrode of the power socket; a positive electrode output end of the voltage conversion circuit is connected with a positive electrode input end of the sound control unit, and a negative electrode output end of the voltage conversion circuit is connected with a negative electrode input end of the sound control unit, and the sound control unit is connected with the light emitting diode and the piezoelectric ceramic piece; and the driving circuit can use the power socket on a vehicle directly to achieve sound control on flash of a melody lamp and amount of humidifying mist. The driving circuit for the vehicle-mounted sound-control flashing humidifier has the advantages of simple and reasonable design, low cost and convenient use.

Description

technical field [0001] The invention relates to a drive circuit for a vehicle-mounted sound-controlled flashing humidifier. Background technique [0002] As one of the most commonly used means of transportation, the current use of automobiles is still growing rapidly. The power socket on the car can be used to provide power to external devices, but because the voltage of the power socket is 12V, some external devices cannot be directly applied. In the use of the car, in order to provide comfort and increase the lively atmosphere, an external LED light flashing is an option, and an external humidifier can also be connected to increase the air humidity to prevent the air from being too dry. However, how to quickly realize the connection of LED lamps at a relatively low cost is a problem that should be considered and solved in the design and production process of LED lamps. Contents of the invention [0003] The purpose of the present invention is to provide a drive circuit...
