Understanding of Woofer Designing and Manufacturing
A woofer is commonly known as a loudspeaker driver designed to produce low-frequency sound. It can produce sounds ranging from about 40 hertz to about 1 kilohertz or more. The name comes from the barking of dogs, woof in contrast with the tweeter. The name was given to speakers designed to reproduce high-frequency sound. The most common design for woofers is the electrodynamic driver. These use a cone powered by a voice coil surrounded by a magnetic field. The combination of a voice coil and magnet forms a linear electric motor. And when current flows through the voice coil, the coil moves with respect to the frame, pushing or pulling the driver cone in the same way that the coil does a piston. The voice coil is attached to the back of the speaker cone using adhesive. The resulting movement of the cone creates sound waves as it moves in and out. Designing and manufacturing woofers is a difficult task. While designing a woofer , keep in mind the following: By controlling the movement o...
