Abstract

The invention discloses a sound post capable of freely combining directions of loudspeakers. The sound post comprises a housing which comprises a mounting plate; and two groups of sound box components which are symmetrically arranged on the surface of the mounting plate. Each sound box component comprises two loudspeakers and a passive radiator, the passive radiators are positioned on the outermost side, and the loudspeakers are fixed on the mounting plate through inclined fixing seats capable of changing the orientations of the loudspeakers. The two bass passive radiators are additionally arranged on the two sides of the sound post, the function that the bass of the four loudspeakers in the middle is insufficient is made up, meanwhile, the sound of the sound post can be rounder, and low frequency is better facilitated.

Description

technical field [0001] The invention relates to the field of audio technology, in particular to a sound column capable of freely combining directions of loudspeakers. Background technique [0002] The sound column is formed by arranging and combining multiple speakers and connecting them in phase. The directional characteristic of the sound column is similar to that of a single speaker in the horizontal direction, but it is greatly improved in the vertical direction. It spreads in a wave pattern in the horizontal direction, but in the vertical direction, it has a strong directional characteristic, forming a "plate" shape. Stereo radiation effect. In layman's terms, the speaker refers to the built-in power amplifier in the main box of the speaker or the subwoofer box. After the audio signal is amplified, the sound is played back by the speaker itself to make the sound louder. [0003] At present, when the existing sound column is in use, the user cannot change the direction...
