DUAL-FREQUENCY COAXIAL EARPHONE
First Claim
1. A dual-frequency coaxial earphone, comprising:
- an earphone housing, having a receiving space and an acoustic output orifice, the receiving space communicating with the acoustic output orifice;
a moving coil loudspeaker unit, disposed in the receiving space, comprising a moving coil vibrating diaphragm and an acoustic transmitting member, the moving coil vibrating diaphragm being assembled to face to the acoustic output orifice and comprising a central vibrating portion, the acoustic transmitting member comprising an acoustic transmitting hole corresponding to the central vibrating portion; and
a balanced armature loudspeaker unit, corresponding to the moving coil loudspeaker unit, comprising an armature vibrating diaphragm corresponding to the acoustic transmitting hole, so that the armature vibrating diaphragm and the moving coil vibrating diaphragm are respectively disposed at two ends of the acoustic transmitting member;
wherein high frequency acoustic waves generated from the armature vibrating diaphragm are transmitted to the central vibrating portion through the acoustic transmitting hole so as to supplement high acoustic frequency extensions the moving coil vibrating diaphragm lacks.

Abstract
A dual-frequency coaxial earphone includes an earphone housing, a moving coil loudspeaker unit and a balanced armature loudspeaker unit. The earphone housing has a receiving space and an acoustic output orifice. The receiving space communicates with the acoustic output orifice. The moving coil loudspeaker unit is assembled in the receiving space and includes a moving coil vibrating diaphragm and an acoustic transmitting member. The moving coil vibrating diaphragm is assembled to face the acoustic output orifice and includes a central vibrating portion. The acoustic transmitting member includes an acoustic transmitting hole corresponding to the central vibrating portion. The balanced armature loudspeaker corresponds to the moving coil loudspeaker unit and includes an armature vibrating diaphragm. The armature vibrating diaphragm corresponds to the acoustic transmitting hole, so that the armature vibrating diaphragm and the moving coil vibrating diaphragm are respectively disposed at two ends of the acoustic transmitting member.
