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. The voice coil is attached by adhesives to the back of the loudspeaker cone. The voice coil and the magnet form a linear electric motor.
What are speaker woofers made of?
Most manufacturers of monitoring speakers make woofers out of paper. Polypropylene — Polypropylene or plastic cones are easy to work with and perform quite well. Since they are reasonably rigid and extremely damped, plastic woofers have a controlled breakup, resulting in a smoother high end roll-off.
What is inside a speaker?
The “Voice Coil” is a coil of wire, typically aluminium or copper which the electrical audio signal flows. The voice coil sits in front of the stationary (fixed) magnet and is connected to the cone allowing amplification of the electromagnetic vibrations, releasing sound waves into the air.
What is inside a powered subwoofer?
A kit for a powered subwoofer contains the subwoofer, an amplifier, audio connectors, and hookup wire. The hookup wire connects the subwoofer to the amplifier internally and permanently, while the audio connectors allow the subwoofer to be connected to a sound source, such as an audio interface or stereo receiver.
How does a woofer work?
When the amplifier sends audio signals to the subwoofer, electric current flows through the voice coil creating a magnetic field that pulls and pushes the voice coil against the magnetic gap. By alternating this current, the voice coil moves upward and downward to produce sound.
What is woofer in speaker?
low-frequency speaker is called a woofer, and the high-frequency speaker is called a tweeter. In many sound reproduction systems a third, or midrange, speaker is also used, and in a few systems there are separate “subwoofers” and “supertweeters” to reproduce the extremities of the audible spectrum.
What is bass in speaker?
Bass corresponds to anything up to 150Hz, or 150 oscillations per second. These are 'low' sounds that when loud you can feel. They are normally produced by a subwoofer in an Orbitsound speaker. The Bass control will cause your speaker to boost or cut these frequencies in what you are listening to.
What is inside Bluetooth speaker?
The main component of the Bluetooth section is a CSR8635 Bluetooth system. This IC, made by CSR, is intended to be used wireless audio products just like this Bluetooth speaker. This Bluetooth module supports Bluetooth 4.0, wireless stereo audio, wired-in audio, ect.
What does the spider do in a speaker?
The Spider fits around the speaker voice coil and is attached to the speaker basket. It is one of the components (along with the cone) that help to keep the voice coil centered in the magnetic gap and affects excursion (movement).
