High Quality Passive Buzzer Module for arduino DIY Kit

The characteristics of the passive buzzer is:
1 passive internal without shock source, so if use dc signal can't make it.Must use 2 k ~ 5 k square wave to drive it.
For more than 2 sound frequency control, can make "m hair sola west" effect.
3 in some particular case, can reuse and LED a control.

The characteristics of the active buzzer is:
1 Active buzzer inside with shock source, so as long as the electricity will call.
2 Program control convenient, single chip microcomputer a high and low level can make the sound, and the passive buzzer is can't do.
Each weight is about 6 g.
