Description::
Passive buzzer without oscillating source inside, so if you use DC signal, you can't make it scream. It must be driven by a square wave of 2K~5K.
The sound frequency is controllable, and the effect of ''do re mi fa so la si do'' can be made.
In some special cases, a control port can be multiplexed with the LED.
Equipped with fixture nuts for convenient mounting.
The module is driven by 9012 transistor.Uses 3 pin control port.
