Buzzer - 10 - DUERR

What is a buzzer?

• An electronic device that produces an audible sound or tone.

• A device that controls the flow of electricity in a circuit.

• A device that measures the amount of light in a room.

• A tool used for cutting metal.

What is the primary purpose of a buzzer?

• Controlling the temperature in a room.

• Measuring the amount of water in a container.

• Generating a warning or notification signal.

• Turning on a light switch.

What is the mechanism used to generate sound in a buzzer?

• A series of buttons that are pressed to produce sound.

• An electromechanical mechanism that vibrates a diaphragm.

• A digital signal that is converted into an analog sound wave.

• A light beam that is interrupted to produce sound.

What are some applications of a buzzer?

• Alarms.

• Timers.

• Confirmation of user input.

• All of the above.

What are the two types of buzzers?

• Electromagnetic and piezoelectric.

• Passive and active.

• Digital and analog.

• Mechanical and electronic.

What is the main difference between a passive buzzer and an active buzzer?

• A passive buzzer generates a tone using an internal oscillator, while an active buzzer requires an AC signal.

• A passive buzzer requires an AC signal to make a sound, while an active buzzer generates a tone automatically.

• An active buzzer generates a tone using an internal oscillator, while a passive buzzer requires an AC signal to make a sound.

• A passive buzzer generates a tone automatically, while an active buzzer requires an external power source.

What kind of voltage is needed for an active buzzer to generate a tone?

• AC voltage.

• DC voltage.

• Both AC and DC voltage.

• No voltage is needed.

Can a passive buzzer differentiate between positive and negative polarity?

• False.

• True.

How does a passive buzzer produce sound?

• By vibrating a diaphragm.

• By generating a tone using an internal oscillator.

• By converting a digital signal into an analog sound wave.

• By interrupting a light beam.

Is there any similarity between passive buzzers?

• No, there is no similarity between passive buzzers.

• Yes, there is a little similarity between passive buzzers.

• Yes, all passive buzzers are exactly the same.

• It depends on the specific model of the buzzer.
