What is the voice coil controller?
voice coil drive is an electromagnetic device that adds control movement for secondary mechanisms. Similarly, in the operating principle as conventional solenoids, it varies in that the control coil moves in a static magnet field. The voice coil drive is also able to produce two -way movement. In addition, its output movement range can be controlled by external triggers and system feedback. Also known as Voice Coil Motors engines can be configured to produce linear and rotary outputs. The most common application of this phenomenon is a simple solenoid. These ubiquitous devices consist of static wire spool and movable piston used as an output transmission agent. When the coil is under electrical voltage, a strong magnetic field is generated that causes a plunger to move in a way to it. This movement is then used to perform work.
voice -drive driveIt also relies on this electromagnetic power to supply its output movement, but does in another way. These drivers have a static magnet field and a movable coil that is used to transmit movement. When electric current passes through the coil, the magnetic field is generated in the same way as a conventional solenoid. This field interacts with the field of static magnet and attracts or repels the coil depending on the phase relationship of both fields. This theory of work can be easily demonstrated by two small magnets of the type that either push each other or towing each other depending on which way they face.
In this way, a voice coil controller or voice coil motor, as are also known, can be used to create a series of finely controlled two -way liniephyb. The drive can also be configured to create a final rotary movement, usually less than 360 degrees. Voice coil drive can also be configured as part of the servic system where the dictation JThe movement range is used by feedback or installation inputs. A very common application for voice coil drivers is the head for reading and writing to your computer's hard disk.
However, one of the most famous uses of the voice coil is the audio speaker. The speaker cone is attached to the voice coil and is moved back and forwards with an alternating polarity of the sound signal passing through the coil. This in turn creates waves of air pressure that produce the sound output of the speaker.
