Abstract

The invention relates to the technical field of combined sound equipment, and discloses a sound equipment folding and unfolding device for solving the problem that the use effect is influenced by dustpollution, the sound equipment folding and unfolding device comprises a shell, and the top of the shell is movably connected with a cover plate; through the combined action of the toothed bar and themovable assembly, the placement condition of the combined sound equipment is controlled according to the use requirements, and the opening and closing operation is triggered by utilizing the operation condition of the combined sound equipment, so that the cover plate does not shield the sound equipment any more, the sound equipment is convenient to move out, the sound equipment is retracted and released under the non-use condition, and the dust pollution is reduced; and the sound equipment can be normally used, is protected, is prevented from being damaged by external impact, and is automatically lifted to be directly exposed to the outside, and compared with a common fixed placement mode, the transmission effect of the sound effect of the sound equipment is improved, the feeling effect is improved, and the sound equipment is more suitable for the actual use condition.

Description

technical field

[0001] The invention relates to the technical field of combined audio equipment, in particular to an audio equipment retractable device that solves the problem that dust pollution affects the use effect. Background technique

[0002] When using a combination speaker, in order to obtain a better playback effect, it is necessary to keep its tweeter at the same level as the listener's ear, so most people will place the speaker at a high place, but this increases the safety of the speaker placement , It is easy to fall and break, which is not conducive to the normal use of the speaker, and the placement of the speaker needs to occupy a certain space on the desktop, reducing the space utilization rate. At the same time, if the speaker is placed for a long time, its surface will be contaminated with a lot of dust, and the dust will fall into the sound amplification hole of the sound, which will block the sound amplification hole, reduce the sound effect of the soun...
