HANDHELD KTV MICROPHONE

A microphone converts sound into electrical signals for recording, amplification, or transmission. Types include dynamic, condenser, lavalier, and shotgun microphones, each suited for different applications. They have various polar patterns (e.g., cardioid, omnidirectional) to determine sound pickup. Microphones can be wired (e.g., 3.5mm, XLR, USB) or wireless (e.g., Bluetooth). They are used for recording, communication, public speaking, and video production. Key considerations include frequency response, sensitivity, and durability.
