Disclosed herein is a virtual multi-channel speaker unit. The virtual multi-channel speaker unit basically comprises a case partially formed with a permeable portion for use as a passage of sound, a solenoid coil provided inside the case and used to transmit sound signals, a magnetic substance on which the solenoid coil is wound to produce a magnetic field, and a vibrator plate, one surface of which faces the magnetic substance to vibrate by the magnetic field, causing sound waves to be propagated through the permeable portion. In addition to the above components, the speaker unit of the present invention further comprises a transmission tube connected to a prescribed position of a rear portion of the case. The transmission tube has an inlet for use as an entrance of the sound waves and air pressures produced at a rear side of the vibrator plate during vibration of the vibrator plate, and an outlet hole formed toward a front side of the vibrator plate for propagating the sound waves and air pressures, which were entered through the inlet hole, to the outside. The virtual multi-channel speaker unit has an effect of relieving listener fatigue and improving sound quality, thereby transmitting sounds similar to original sounds. |
