26 results about "Woofer" patented technology

A woofer or bass speaker is a technical term for loudspeaker driver designed to produce low frequency sounds, typically from 20 Hz up to 500 Hz. The name is from the onomatopoeic English word for a dog's bark, "woof" (in contrast to the name used for speakers designed to reproduce high-frequency sounds, tweeter). The most common design for a woofer is the electrodynamic driver, which typically uses a stiff paper cone, driven by a voice coil surrounded by a magnetic field.
