Abstract
Disclosed herein is a slit-firing speaker apparatus capable of full frequency band reproduction. The speaker apparatus includes a speaker unit configured to generate sound, an enclosure, in which the speaker unit is installed, configured to block rearward sound to prevent the rearward sound of the speaker unit from being mixed with forward sound of the speaker unit, and a reflection plate configured to cover the speaker unit and coupled to the enclosure to form an acoustic path through which the generated sound travels. The acoustic path includes a radiation part formed at one end of the acoustic path and radiating the generated sound, and an opening part formed at the other end of the acoustic path.
