Loudspeaker device with integrated labyrinthine bass reflex port and multidirectional reflection structure

Abstract

Loudspeaker device with integrated labyrinthine bass reflex port and multidirectional reflection structure, comprising a box body (1) wherein a woofer (2) is mounted on the underside of the box body (1);characterized in that the box body (1) has an inner cavity of the box body (101), wherein a labyrinthine bass reflex channel (4) is arranged in the inner cavity of the box body (101), wherein an inlet of the labyrinthine bass reflex channel (4) is located in the inner cavity of the box body (101) and near a rear side of the woofer (2), wherein the labyrinthine bass reflex channel (4) comprises a first horizontal section (401) extending horizontally from the inlet, a vertical section (402) extending vertically downwards from an end of the first horizontal section (401), and a second horizontal section (403) extending horizontally from an end of the vertical section (402), wherein an end of the second horizontal section (403) is connected to a sound outlet opening (3) formed on a bottom flank of the box body (1);that a spherical reflection device (5) is located directly below the woofer (2), the spherical reflection device (5) having an arc-shaped reflection surface (501) facing the woofer (2) in order to reflect downward sound waves emitted by the woofer (2) and to direct them to a sound emission opening (9) formed on the underside flank of the box body (1); and that the sound emission opening (3) and the sound emission opening (9) are both formed on the underside flank of the box body (1) and are separated by a partition (8).
