Microphone Types and Functions

What fundamental principle do both dynamic and condenser microphones share?

• They both use a coil and magnet.

• They both require external power.

• They both convert acoustic energy into electrical voltage.

• They both have a heavy moving diaphragm.

Which set of components is essential for a dynamic microphone to function?

• Diaphragm, backplate, amplifier

• Diaphragm, coil, magnet

• Capacitor, resistor, inductor

• Transmitter, receiver, antenna

What is a crucial characteristic for the material used in a dynamic microphone's diaphragm?

• It must be metallic.

• It must be heavy.

• It must be lightweight.

• It must be transparent.

How does a dynamic microphone generate an electrical signal?

• By changing the distance between a charged diaphragm and a backplate.

• By vibrating a coil within a magnetic field.

• By converting light energy into electrical energy.

• By using a piezoelectric crystal.

What are the three key elements of a condenser microphone?

• Diaphragm, coil, magnet

• Diaphragm, backplate, amplifier

• Ribbon, transformer, power supply

• Crystal, preamplifier, housing

How does a condenser microphone produce an electrical signal?

• By the movement of a coil in a magnetic field.

• By changes in the electrical field between a conductive diaphragm and a charged backplate.

• By the friction of air against a sensitive membrane.

• By converting sound waves directly into digital data.

Why does a condenser microphone require an electrical circuit (impedance converter)?

• To make the signal more vulnerable to interference.

• To reduce the output voltage.

• To add more current and make the signal suitable for amplification.

• To convert the electrical signal back into acoustic energy.

What is a common source of external power for a condenser microphone?

• A standard AA battery.

• Phantom power from a console.

• Solar energy.

• Kinetic energy from sound waves.

Which type of microphone is generally considered more precise due to its lightweight diaphragm construction?

• Dynamic microphone

• Ribbon microphone

• Condenser microphone

• Crystal microphone

Which microphone type is better suited for accurately capturing fast bursts of energy, such as from a snare drum or piano?

• Dynamic microphone

• Condenser microphone with a small diaphragm

• Ribbon microphone

• Carbon microphone
