An installation structure of a rotating outdoor sound column

Abstract

The invention discloses a mounting structure of a rotary outdoor sound post, and relates to the technical field of sound posts. Themounting structure comprises a mounting sleeve and a loudspeaker column body, wherein one side of the loudspeaker column body is provided with a connecting piece along the length direction; A sliding plate is arranged on one side of the connecting piece; The sliding plate is of an arc-shaped plate structure, and the column loudspeaker body is rotationally matched with the peripheral side of the mounting sleeve through the sliding plate; The mounting sleeve is of acylinder structure, and limiting pieces are arranged at the two ends of the cylinder; The two limiting pieces are of a circular ring structure, and a groove channel is formed in one surface of the circular ring. The two ends of the sliding plate are in sliding fit in the two channels respectively; Arc-shaped guide rails are evenly distributed on the peripheral side face of the mounting sleeve. Thecolumn loudspeaker body is mounted on the mounting sleeve through the arc-shaped guide rail, the position of the column loudspeaker body on the mounting sleeve is limited through the two limiting pieces, electric rotation of the column loudspeaker body on the mounting sleeve is achieved, broadcast information can be spread in different directions conveniently, and the mounting cost of the broadcast terminal is reduced.

Description

technical field [0001] The invention belongs to the technical field of sound columns, and in particular relates to an installation structure of a rotary outdoor sound column. Background technique [0002] Outdoor sound column is a kind of speaker. Generally, the sound column is loaded with 4-10 paper cone speakers in the vertical direction. This arrangement results in strong directivity in the vertical direction, and the high-frequency directivity is more prominent. [0003] At present, in order to obtain a wider broadcasting effect, the existing outdoor sound columns generally install sound columns in two different directions on the column at the same time, so as to make the sound spread wider and farther, but in this way This causes an increase in cost, and when the sound column is damaged, the installation cost is increased, which is not convenient for large-scale popularization and use. Contents of the invention [0004] The purpose of the present invention is to pr...
