What Is A Balanced Armature Driver?

writer:admin pubdate:2016-08-11 16:00 view:()

A balanced armature is a sound transducer design which is primarily intended to increase the electrical efficiency of the element by eliminating the stress on the diaphragm characteristic of many other magnetic transducer systems. As shown schematically in the diagram, it consists of a moving magnetic armature that is pivoted so it can move in the field of the permanent magnet. When precisely centered in the magnetic field there is no net force on the armature, hence the term ‘balanced.’

As illustrated in the diagram, when there is electric current through the coil, it magnetizes the armature, causing it to rotate slightly one way or the other about the pivot thus moving the diaphragm to make sound.

In simple terms, the coil is held in the middle by two magnets until it’s stimulated by an electrical current, causing the diaphragm to vibrate thus creating a sound wave. This sound wave then moves its way through the sound hole of the driver, through the earphone and into your eardrum… BAM! musical nirvana!
