High frequency compression drivers

摘要

The compression driver includes an annular diaphragm with a voice coil which is disposed in a magnetic gap of a magnet assembly which supplies a magnetic field to the voice coil. The annular diaphragm has a first support portion, a second support portion, a first curved resilient portion, a second curved resilient portion and a voice coil support portion which is disposed between the first and second resilient curved portions. The voice coil is wound on the voice coil support portion. The voice coil is disposed in the magnetic gap of the magnet assembly. The compression driver also includes an inner support ring and an outer support ring. The inner support ring has a bottom surface with a first curved groove. The outer support ring has a bottom surface with a second curved groove and is disposed concentrically around the inner support ring.
