A liftable and rotatable anti-drop sound box

Abstract

The invention discloses a liftable and rotatable anti-drop sound box. The sound box comprises a mounting back plate and a lifting seat; the mounting back plate is fixedly mounted on a wall surface, aU-shaped groove is formed in the front surface of the mounting back plate, and two first screw rods are symmetrically and rotationally mounted on the left side and the right side of the U-shaped groove; The first screw rod is further in threaded connection with screw sleeves, the two screw sleeves are in sliding connection with the U-shaped groove, and the left side and the right side of the lifting base are fixedly connected with the two screw sleeves correspondingly; A mounting plate is arranged on the lower side of the lifting base, the left side and the right side of the mounting plate arefixedly connected with the lifting base through supports, and a rotating disc is rotationally mounted in the mounting plate. A sound installation base is further arranged on the lower side of the rotating disc, the sound installation base is of a hollow box structure, and a sound is arranged in the sound installation base. The loudspeaker box can be driven to move up and down, the loudspeaker boxcan be driven to rotate, meanwhile, vibration force is absorbed and converted when the loudspeaker box mounting base falls off accidentally, and the loudspeaker box is protected from being damaged.

Description

technical field [0001] The invention relates to the field of audio technology, in particular to a liftable and rotatable anti-drop audio system. Background technique [0002] Sound refers to sounds other than human language and music, including sounds from the natural environment, animals, machines and tools, and various sounds from human actions. [0003] Audio probably includes power amplifiers, peripheral equipment (including compressors, effects, equalizers, VCD, DVD, etc.), speakers (speakers, speakers), mixers, microphones, display devices, etc. add up to a set. Among them, speakers are sound output devices, speakers, subwoofers and so on. A speaker includes high, low, and medium speakers, three but not necessarily three. The development history of technology can be divided into four stages: tube, transistor, integrated circuit, and field effect tube. [0004] Most of the existing audio and sound effects are controlled by internal electronic technology, but the loca...

AI Technical Summary

Problems solved by technology

[0004] Most of the existing audio and sound effects are controlled by internal electronic technology, but the location of the audio installed in the room is different, the refraction and reflection of the sound are also different, and the sound effect will change accordingly. Most of the installation positions are fixed and cannot be adjusted, which will affect the use of the sound
