Loudspeaker box capable of realizing directional sound production and multi-angle rotation

Abstract

The invention discloses a loudspeaker box capable of realizing directional sound production and multi-angle rotation. The loudspeaker box comprises a directional sound production box; the surface of the directional sound production box is movably connected with the surface of a locking clamp; the side surface of the locking clamp is fixedly connected with an adjusting device; the adjusting deviceis fixedly connected with the surface of a rotating table through a bearing; the bottom surface of the rotating table is fixedly connected with one end of a rotating shaft; the rotating shaft is movably connected with the surface of an upper base through a bearing; the upper surface of the upper base is movably connected with a fine adjusting switch; the upper base is rotationally connected with the surface of a rough adjusting switch through a bearing; and the upper base is fixedly connected with a lower base through a rotary shaft. According to the loudspeaker box capable of realizing directional sound production and multi-angle rotation, the rotating shaft is driven to rotate by rotating the rough adjusting switch, so that the directional loudspeaker box is enabled to horizontally rotate; the fine adjusting switch moves up and is rotated, so that the directional loudspeaker box is finely adjusted in a horizontal direction; and the rotation of the directional loudspeaker box in a vertical direction is adjusted through the adjusting device.

Description

technical field [0001] The invention relates to the technical field of sound boxes, in particular to a sound box capable of directional sound emission and multi-angle rotation. Background technique [0002] Directional speakers use ultrasonic technology to combine sound waves and sound waves that can be heard by the human ear, and take the strengths of ultrasonic waves to make up for the shortcomings of audible sound waves. Audible sound waves have no directionality, while ultrasonic waves have good directionality. Therefore, ultrasonic It can be used as a medium for carrying audible sound waves in one direction, and the propagation distance can be as long as 100 meters. It can realize sound transmission and encryption, and only people in the covered area can hear the sound. However, the existing directional speakers can only be placed simply, can only be adjusted horizontally, and cannot be adjusted at multiple angles. When people move their positions, it is very difficult ...
