The concept is an easy one to understand. An accelerometer mounted to the woofer voice-coil is used to continuously monitor the motion of the woofer cone. ... With the servo system, the circuit senses that the woofer is not moving as fast as it should, and it applies more current to make it move faster.
How does a servo woofer work?
Direct Servo uses a very thin sensing coil which is wound adjacent to the voice coil. The coil acts as a custom made microphone which creates a signal which is then used to correct any difference from the original signal. Any non linearities are instantly corrected.
What is a servo audio amplifier?
In the context of audio circuits, a servo is usually an active element used in feedback in order to null or reduce an amplifier's offset voltage. "Servos provide a sophisticated way to reduce offset voltages in audio circuits"Dec 6, 2006
How does a Rotary subwoofer work?
A rotary woofer is a subwoofer-style loudspeaker which reproduces very low frequency content by using a conventional speaker voice coil's motion to change the pitch of an impeller rotating at a constant speed.
What is servo woofer?
The Genesis® Servo-Controlled Bass System reduces distortion to imperceptible levels at any reasonable loudness. In order to convey the bass frequencies accurately, a woofer has to move extremely forcefully in the air load of the room. ... The solution for this is the Genesis Servo-Controlled Bass System.
What is the difference between a subwoofer and a woofer? There are no stark differences between these two speaker systems as both are used to reproduce low-frequency sound notes. Subwoofers are designed to reproduce a band of frequencies below 30Hz level and woofers produce sounds above it.Apr 1, 2007
What is a servo controlled amplifier?
Servo amplifiers, or servo amps for short, are drives that are used to power electronic servomechanisms, such as servo motors. A servo amp transfers signals from the command module of the robot, and translates them for the servo motor, so the motor knows how much it should move at any given time.
What does a servo controller do?
The job of the servo motor controller (or commonly referred to as the motion controller) is to close the loop on the system by constantly looking at the encoder signal and applying a torque to the motor in order to control it. The simplest form of this is to hold a specific position.
How does a sub work?
The subwoofer amplifies the current and converts it to sound through the use of a magnetic coil that causes vibration of the driver's cone. This vibration results in low frequency sound waves being sent out through the air.
