Piezoelectric buzzer as the audio signal generator has a wide range of uses, low power consumption as they are, sound clarity and penetration. External buzzer drive circuit or drive circuit requirements of oscillation in the resonant frequency of piezoelectric components. Piezoelectric element at its resonant frequency to provide the maximum output sound pressure. However, a [...]

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. [...]

Electrical equipment rated current is defined as the baseline ambient temperature in the working conditions of rated voltage, the heat does not exceed the long-term temperature by allowing heat to allow the greatest long-term through the current. Ambient temperature for long-term allows the maximum current has a great impact , as the equipment installation location [...]
