Abstract
The invention discloses a rotary sound box for a stage. The rotary sound box comprises a sound box and a sound box separation plate; a sound box limiting device is fixedly installed over the sound box; a stretchable rod is arranged below the sound box; a sound amplification device is arranged in the middle of the sound box; a buffer rod is installed in an upper buffer device protective shell; a stretchable spring is arranged on the buffer rod; a lower buffer device protective shell is arranged below a rotary control device; and a lower connecting rod is arranged on the lower buffer device protective shell. Compared with the prior art, the rotary sound box disclosed by the invention has the benefits that: the rotary sound box for the stage is scientific and reasonable in structure and safe and convenient to operate; an LED stage lamp is installed on the sound box; the rotary control device is installed in the sound box; with the help of the LED stage lamp on the sound box, audiences can feel the visual feast of the sound box; and thus, the charm due to the whole stage can be greatly improved.
Description
technical field [0001] The invention relates to the technical field of audio, in particular to a rotary stage audio. 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. Audio probably includes power amplifiers, surrounding 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. [0003] However, there are some deficiencies in the existing stage speakers during use. The stage speakers are all placed in a fixed place and are only used for the amplification of the sound on the stage, so that the audience can not feel the sound. The visual effects brought about...
