Abstract:
1. An earphone device, comprising: a crossover unit configured to convert an electrical signal into a first component comprising a first frequency range and a second component comprising the second frequency range; a first speaker unit corresponding to one of a left or right channel and including a first balanced armature transducer signal, wherein configured to be responsive to the electrical signal at the first frequency range and a second balanced armature transducer configured to be responsive to the electrical signal at the second frequency range; a second speaker unit corresponding to the other of the left or right channel and including a third balanced armature transducer configured to be responsive to the electrical signal at the first frequency range, and a fourth balanced armature transducer configured to be responsive to the electrical signal at the second frequency range; an impedance correction unit configured to: a plug that interfaces with an amplifier; a first wire corresponding to the left channel that couples the crossover unit to the to the plug; a second wire corresponding to the right channel that couples the crossover unit to the plug; a third wire and a fourth wire that couple the first speaker unit to the crossover unit; and a fifth wire and a sixth wire that couple the second speaker unit to the crossover unit; wherein the first and second wires are mechanically coupled to form a Y-junction of the wires, and wherein the crossover unit is positioned at or near the Y-junction of the wires.
