making a speaker

I made a speaker in school. Before I made that. I studied about sound. It moves by vibration like my vocal cords.
This story made me interesting. I started to make a speaker. Actually, it was the smae principle as the actual speaker.
And then I was making it. "Oh, my god." The cable that my teacher gives didn't fit with my Calibration Battery.
So, I couldn't make it. But my friend was no exception. So, we just saw that, My teacher also made it.
So, we looked around. But it was excited.
