Modern society, along with the progress of science and technology and the development of life, various audio amplifier equipment are applied to places such as family, office, factory, public place widely.Yet, with regard to the audio amplifier that prior art provided, though the realization playing function can be provided.But still have following shortcoming: 1, audio amplifier takes up space greatlyyer, can not carry when going out, and uses inconvenience.2, the loudspeaker long term exposure of audio amplifier is in air, and speaker net contacts with dust, causes the loudspeaker performance degradation, influences tonequality, and useful life is shorter.
Summary of the invention
Take up space greatlyyer in order to solve in the prior art audio amplifier, can not carry the loudspeaker performance degradation when going out; influence tonequality, the problem that useful life is short the invention provides a kind of simple in structure; multifunctional combined type lifting soundbox easy to use, as can to carry out fine protection to speaker.
In order to achieve the above object, the technical solution used in the present invention is:
A kind of multifunctional combined type lifting soundbox, comprise two lifting soundboxes, described two lifting soundboxes are connected by signal connecting line, be connected with the power supply that electric power is provided on a lifting soundbox therein, described lifting soundbox comprises the rectangular plastic magazine, described rectangular plastic magazine is by front and back panel, left and right sides panel, the upper and lower panel composition that matches, it is characterized in that: also comprise the handle lid, handle, shell, the shell locking nut, speaker net, loudspeaker, control button, vertically be disposed with two loudspeaker installing holes in rectangular plastic magazine front panel upper part, in each loudspeaker installing hole loudspeaker are installed, are provided with speaker net in the place ahead of loudspeaker installing hole; The back side at rectangular plastic magazine front panel end portion is provided with pcb board, and described control button is arranged on the front of front panel end portion, and is connected with pcb board, and rectangular plastic magazine top panel is provided with the handle lid, covers at handle and is provided with handle; Vertically be provided with sliding rail in the enclosure, described rectangular plastic magazine is installed in the enclosure, and can slide up and down along sliding rail, the shell locking nut that has locking effect at the sheathed one deck in the outside of shell.
Aforesaid a kind of multifunctional combined type lifting soundbox is characterized in that: the both sides of described rectangular plastic magazine top panel are respectively equipped with groove, are respectively arranged with embedded block in the inwall both sides of handle lid, and described embedded block matches fixing with groove.
Aforesaid a kind of multifunctional combined type lifting soundbox is characterized in that: the length of described shell is greater than two combined vertical extension of loudspeaker installing hole of front panel.
The invention has the beneficial effects as follows: the rectangular plastic magazine of multifunctional combined type lifting soundbox of the present invention can move up and down in the enclosure; it is less to take up space; during use the rectangular plastic magazine being proposed to expose two loudspeaker uses; when not using the rectangular plastic magazine is pressed into enclosure and covers protection; loudspeaker can not be exposed in the air for a long time like this; be difficult for wearing out, playback effect is better, and useful life is longer.
