Portable square sound box

Abstract

The invention discloses a portable square sound box which comprises a box body, supporting legs, a pulling rod and universal wheels. The supporting legs and the universal wheels are respectively and uniformly mounted at the bottom end of the box body, and anti-collision protection sleeves are uniformly mounted at positions of four corners of both sides of the box body; anti-collision reinforcing plates are uniformly mounted at both sides of the box body; a handle is mounted at the center of the top of the box body; the pulling rod is mounted at one side of the box body; a dustproof reinforcingnet plate is mounted at the center of the other side of the box body; a fixed seat is mounted at one side inside the box body, which faces away from the dustproof reinforcing net plate; and sound boxes are uniformly mounted at one side of the fixed seat, which faces away from a heat dissipation fan, and inside the box body. According to the invention, by mounting the sound box, the supporting legs, the pulling rod and the universal wheels and arranging sound absorption cotton at the centers inside sound absorption barriers mounted at both ends of the sound boxes, the portable square sound boxis convenient to absorb noise by the sound absorption cotton in the playing process of the device and a noise reduction effect of the device is improved, thereby facilitating use of the device.

Description

technical field [0001] The invention relates to the technical field of sound boxes, in particular to a portable square sound box. Background technique [0002] Sound refers to sounds other than human language and music, including sounds of the natural environment, sounds of animals, sounds of machine tools, and various sounds from human actions. A machine that extends the range of sound transmission. [0003] Most of the existing sound boxes for squares are large in size, inconvenient to hold and move, poor in convenience and applicability during use, and most of the existing sound boxes have poor compression and anti-collision capabilities, and are easily affected by external forces. Extruded and deformed, it is easily damaged by impact force, and it is not convenient for fixed use. At the same time, most of the existing square audio boxes have mixed sound, poor reverberation effect, poor dynamic performance, poor heat dissipation effect, and cannot be quickly identified a...
