Triode transistor in buzzer role is the role of the voice signal amplification. Triode is a control component, mainly used to control the current size to a total emitter Connection Example (signal from the base input, the output from the collector , emitter grounded), when the base voltage UB has a small change, base current IB will follow a small change, subject to the control of base current IB, the collector current IC will be a great change , the greater the base current IB, the greater the collector current IC, whereas the smaller base current, collector current is smaller, that is, the base current controls the collector current changes. However, changes in the collector current changes than the base current is much greater, this is the transistor’s amplification.
