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.

Abstract: According to an exemplary embodiment, a display apparatus includes: a display device configured to display a video data; and a plurality of integrated speakers configured to output a plurality of audio signals in a low-pitched tone band and a middle and high-pitched tone band. The plurality of integrated speakers may each include: a woofer speaker configured to output a first audio signal of the audio signals in the low-pitched tone band; and at least one front speaker which is adjacent to the woofer speaker and configured to output a second audio signal of the audio signals in the middle and high-pitched tone band.
