A conical driver refers to a speaker driver that uses a cone-shaped diaphragm to produce sound. This cone, typically made from materials like paper, plastic, or metal, moves in and out to push air and create sound waves. The conical shape is efficient at converting energy into sound across a wide range of frequencies and is common in many types of speakers. This shape helps in evenly distributing sound waves, contributing to the driver's ability to deliver clear and dynamic audio.
