Power supply input voltage: 24V DC;
Power supply current: 2A-3A;
Power supply interface: Both positive and negative in 5.5-2.1;
Circuit board size: 5.4CMx5.4CM;
Coil size: The diameter of 5.05CM is about 7CM
DIY bulk weight: 135 grams; Finished product: 115 grams;
Coil number: The 250 circle, the enameled wire with a coil diameter of 0.2, is wrapped around the coil.
The volume of the volume will be larger than the volume of the headset;
Audio interface: The 3.5 socket can pick up the audio source of mobile phone, MP3 and computer.(the computer audio interface is 3.5, the audio line used 3.5 to 3.5 audio line, mobile phone and MP3 interface is different, please use the corresponding audio line to turn 3.5).If there are other voltage and current sources which are not up to the requirements, or devices will burn out, the loss will be borne by the buyer.
Some buyers think that the power supply is 24V, then the input 12V device will not be damaged. This understanding is wrong. The circuit will eventually constitute an oscillating circuit.
If the voltage and current are not enough, the circuit will not oscillate, which will cause the transistor to directly connect to the ground, and the transistor will burn down.
