Assembled speaker kit PSK-1 130-270 1 set

The structural principle of the speaker can be easily understood. We will experiment with a simple coil made from a paper cup and a ferrite magnet, and show that passing an electric current through it turns it into a speaker. If you connect a lead wire with an electronic melody to a simple coil and attach a magnet to the bottom of a paper cup, it will act as a vibrating plate and play the melody. The speaker is assembled so you can easily understand the structural principle of the speaker. Simple coil (600 turns): Inner diameter 40 mm, outer diameter 50 mm, thickness 7 mm, resistance approx. 50 Ω x 1 Ferrite magnets: 3 1 lead with electronic melody Battery box: For 2 AA batteries (batteries not included) Paper cups: 5 x 500 mL Product code: 130-270
