description: LED and other electrical power supply circuits are the same. If the switching power supply circuit is used, the load can get a good quality DC power supply, but the circuit diagram is complicated and inconvenient to make. Here is a simple circuit for the LED driver power supply circuit diagram. The components in the LED driving power supply circuit are also few, which are convenient to manufacture, and the component parameters are in the circuit for reference. The LED driver power supply circuit diagram is as follows:
Headband Headphones have good sound field and are comfortable to wear, Bluetooth Headband Headphones can avoid scratching the ear canal; the sound quality of high, medium,and bass are very good, have a good sense of hearing even when playing symphony; The midrange effect of the headphones is thick, pop songs' hearing effect is very contagious, music effect is great.
Advantages:
1: Sound field is good, comfortable to wear.
2: No in-ear, avoid scratching the ear canal.
3: longer time to use, compare to in-ear earphone.
