This is used in the lift button on a circuit through the hardware circuit to achieve the buzzer background about the driver as follows:
1. Due to the limited space available in the circuit can only choose SMD passive buzzer (original height-saving considerations, the high active), which implies the need for oscillation circuit, he can work.
2. [...]

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 [...]
