The difference between the installation buzzer circuit

Posted on 15-05-2009 by microbuzzer

Passive electromagnetic and piezoelectric buzzer to install passive
Buzz passive electromagnetic inductive load devices are the ideal square wave input is usually recorded as being: VO-P.
Buzz passive pressure load is capacitive devices, the ideal square wave input is usually recorded as two-way: VP-P.
However, if the IC is the reverse, such as device 4049, from a non-door [...]
