Abstract:
An apparatus includes a horn bracket, a magnet system and a vibration system, where the horn bracket includes a through hole configured for positioning the magnet system, the magnet system includes an inner magnetic ring and an outer magnetic ring sleeved on an exterior of the inner magnetic ring, the inner magnetic ring is coaxial with the outer magnetic ring, a gap is provided between an inner annular surface of the outer magnetic ring and an outer annular surface of the inner magnetic ring, where the inner annular surface and the outer annular surface have opposite magnetic polarities, magnetic flux lines formed in the gap by the outer magnetic ring and the inner magnetic ring are radially disposed, the vibration system includes a voice diaphragm, a voice coil having one end coupled to the voice diaphragm, and a winding coupled to the other end of the voice coil.

Claim (Index 17):
The headphone of  claim 15 , wherein the magnet system further comprises a magnetic shield assembly, wherein the magnetic shield assembly comprises:\n a first magnetic shield assembly disposed on one side of the inner magnetic ring and the outer magnetic ring and directly opposite to the voice diaphragm and comprising:\n a first inner magnetic member in an annular shape and coupled to one side of the inner magnetic ring; and \n a first outer magnetic member sleeved on an exterior of the first inner magnetic member and coupled to one side of the outer magnetic ring, wherein both a side face of the first outer magnetic member and a side face of the first inner magnetic member, facing towards the voice diaphragm configured to:\n comprise opposite magnetic polarities; and \n form a closed first annular magnetic circuit therebetween; and \n \n a second magnetic shield assembly disposed on another side of the inner magnetic ring and the outer magnetic ring and comprising:\n a second inner magnetic member in the annular shape and coupled to the other side of the inner magnetic ring; and \n a second outer magnetic member sleeved on the exterior of the second inner magnetic member and coupled to the other side of the outer magnetic ring, wherein both a side face of the second inner magnetic member and a side face of the second outer magnetic member, facing away from the voice diaphragm are configured to:\n comprise opposite magnetic polarities; and \n form a closed second annular magnetic circuit therebetween.
