A large diaphragm microphone is a type of microphone that uses a large diaphragm, with a diaphragm diameter typically greater than or equal to 3/4 inches, and some large diaphragm microphones even have a diaphragm area greater than 1 inch (25.4mm). This design allows the large diaphragm microphone to capture more sound details and produce a significant low-frequency response, making it particularly ideal for recording sound with specific characteristics, such as vocals.
