What type of microphone is characterized as bulky and uses physical movement to create an electrical signal?

The dynamic microphone is characterized by its bulkiness and its method of generating an electrical signal through physical movement. This type of microphone operates using a diaphragm attached to a voice coil. When sound waves hit the diaphragm, it moves, causing the voice coil to move within a magnetic field. This motion induces an electrical current, which is converted into an audio signal.

Dynamic microphones are often favored for their durability and ability to handle high sound pressure levels, making them suitable for live performances and various recording situations. The design of these microphones typically includes rugged materials, which contributes to their bulkiness compared to other types, such as condenser or ribbon microphones, which can be more delicate and sensitive. This quality further emphasizes the dynamic microphone's role in applications requiring robust equipment.
