Lightning Tesla Coil Speaker

Why choose it:
1.It is a perfect teaching tool to spark students' interest of science, also a great gift.
2.Make the use more cool and fascinating：This music tesla has the function of wireless transmission and loudspeaker, can light gaseous tube and kind of bubbles.
3.Make teaching more convenient：It is a smart device for wireless transmission experiments. It can be used to create high-voltage lightning and do various scientific experiments, such as wireless power transmission, wireless lighting, and insulator withstand voltage test.
4.Provide better quality than ordinary products：This music tesla has circuit protection design, can play music in better quality than normal arc plasma loudspeaker.Adopt a newly designed PCB circuit board, the circuit design is reasonable.
5.More convenient to use：BT connection, convenient and fast.

Attention:
1.  In Bluetooth and lightning mode it is recommended to use the device for about 10 minutes, then you need to disconnect the power supply to let the device stand for a period of time until the bottom of the heat dissipation and then use it again, if you use it for a long period of time uninterruptedly, it is easy to burn the MOS tube of the device
2.  After connecting the Bluetooth mode, you need to adjust the volume of the phone's sound to the maximum, the Tesla coil in order to release the electric arc
