The invention relates to the technical field of sound posts, in particular relates to a multifunctional sound post. The multifunctional sound post comprises a mounting base, wherein a supporting pipeis vertically fixed to the upper portion of the mounting base; the supporting pipe comprises an outer pipe I fixed on the mounting base; an inner pipe I is fixed on the mounting base in the outer pipeI; a connecting cavity I in a sealed state is formed between the outer pipe I and the inner pipe I; the connecting cavity I is in a vacuum state; the connecting cavity I is a circular ring body; a loudspeaker is further fixed to the portion, inside the inner pipe I, of the mounting base; a fixing disc is further fixed to the portion, inside the inner pipe I, of the mounting base; a rotating motoris fixed to the fixing disc; a rotating shaft is fixed to an output end of the rotating motor; a fixing block is fixed to the upper end face of the rotating shaft; a mounting pipe is fixed to the fixing block; and a horn is further fixed to the mounting pipe. The single directivity of the sound post can be realized through utilizing the multifunctional sound post.
Description
【Technical field】 [0001] The invention relates to the technical field of sound columns, in particular to a multifunctional sound column. 【Background technique】 [0002] The sound column is divided into indoor sound column and outdoor sound column, and the broadcast motor generally uses an outdoor sound column. Generally, the sound column is loaded with four to ten paper cone speakers in sequence in the vertical direction. This arrangement makes the sound column There is a strong directionality. However, the current sound column cannot achieve complete unidirectionality, that is, only one direction can receive the sound from the sound column, and it is also impossible to change the direction of the sound from the sound column, and it is impossible to confirm that the sound is aimed at the sound column The sound from the position in the direction of the sound can only be broadcast in all directions through the outdoor sound column, but it cannot be broadcast in a precise dire...
