Abstract:
The present invention relates to a speaker apparatus for reproducing a sound from an electrical signal and, more specifically, to a voice coil speaker apparatus capable of reproducing a high-fidelity sound over a wide frequency band.

Claim (Index 1):
In a speaker apparatus using magnet and voice coil means, the speaker apparatus comprising:\n a magnetic circuit part for applying DC (direct current) magnetic flux to the voice coil, which configured by stacking a magnet, a pole piece, and two plates, thus having two magnetic air gaps in a ring shape; a speaker frame fixedly attached to the magnetic circuit part; two voice coils divided into a first voice coil and a second voice coil to apply different currents to the voice coils, respectively; a voice coil bobbin, the two voice coils being wound around the voice coil bobbin so as to be positioned in the two magnetic air gaps and performing vibrational motion according to a difference between forces generated by currents applied to the two voice coils; a diaphragm bonded to one side of the voice coil bobbin to convert the vibrational motion of the voice coils into vibration of air to generate sound; a displacement sensor module to sense the vibration displacement of the diaphragm for feedback to a driving device; a vibration part support attached to an outer periphery of the voice coil bobbin to support the voice coil bobbin on a speaker frame; and a hinge configured to connect the vibration part support to the speaker frame to allow a speaker vibration part to perform accurate vibrational motion in the magnetic air gaps along a central axis of speaker, the speaker vibration part including the two voice coils, the voice coil bobbin, the vibration part support and the diaphragm.
