Special Features: 1. Wireless Transmission: This musical Tesla has the function of wireless transmission and loudspeaker and can ignite gas pipes and various bubbles. It is the perfect teaching tool to stimulate students' interest in science and a great gift. 2. Protection Design: This musical Tesla features a circuit protection design that does not damage input devices and can play music with better quality than conventional arc plasma speakers. 3. Easy Operation: Bluetooth-compatible connection, convenient and fast. Using a newly designed PCB circuit board, the circuit design is reasonable. 4. Wide Application: This is a smart device for wireless transmission experiments. It can be used to generate high-voltage lightning and conduct various scientific experiments such as wireless power transmission, wireless lighting, and insulator withstand voltage testing. Teachers use it to demonstrate the principles of augmentation and high-frequency skinning effects to students. The gold-plated coil design features a clear and complete winding coil, making the basic structure of a Tesla coil easy to understand. It is beautiful and stylish, and has good durability. The interference-resistant circuit design is not affected by high-frequency electromagnetic signals, so you can use it with confidence. The Tesla coil can generate a high-frequency and high-pressure electromagnetic field, allowing lights containing conductive gases to be illuminated by the electromagnetic field. The Tesla coil is designed to be easy to use and operate. Through wireless transmission, the Tesla coil can generate high-temperature and high-pressure plasma, which can support wirelessly turning on your lights and ignite without contact. BT connection for playing mobile phone music, directly onboard the BT chip, with an antenna for searching for BT M18. Switch to music mode to start playing music.
