什么是“麦克风效应” |
Ah Tai means "microphonic".
When the tube shows microphonic, you will hear poping noise from the speaker when you hit the tube. It more or less like a noise pickup transducer or a microphone.
The rubber band surrounding the tube is to damp the airborn vibrations
from the sound wave that hit the tube to make noise.
