A retractable cooling speaker

Abstract

The invention discloses a telescopic heat radiation sound box, which comprises a base, wherein a plurality of universal wheels are arranged at the bottom of the base; a braking mechanism is arranged on the universal wheels; a fixing plate is sleeved on the top of the outer wall of the base; a plurality of first hydraulic cylinders are arranged at the bottom of the fixing plate; an auxiliary plateis sleeved under the fixing plate at the outer side of the base; an outer box body is arranged on the top of the base; a sound box body is arranged inside the outer box body in a matched way; a waterstorage layer is arranged at the inner wall of the outer box body; a heat radiation layer is arranged on the outer wall of the sound box body; a plurality of water conveying pipes are arranged on thetop of the inner side of the water storage layer; a plurality of second hydraulic cylinders are arranged on the top of the fixing plate; regulating chambers are symmetrically arranged at the two sidesinside the water storage layer; a rotating rod, a first gear, a second gear, a second movable rod, a second rack, a push plate, a first movable rod, a first rack and a connecting block are horizontally arranged inside the regulating chamber; a first fixing block and a second fixing block are arranged on the outer wall of the heat radiation layer. The sound box has the advantages that the use is convenient and fast; the stability is high; the telescopic effects can be realized; the heat radiation effect cannot be influenced in the telescopic process.

Description

technical field [0001] The invention relates to the field of audio technology, in particular to a telescopic heat dissipation sound box. 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 audio technology can be divided into four stages: tubes, transistors, integrated circuits, and field effect tubes. [0004] A speaker refers to a device that converts an audio signal into sound. In layman's terms, it refers to t...
