Description
Technical field
Storage battery speaker technology field is the utility model is related to, specially a kind of LED lights movable type storage battery audio amplifier.
Background technology
Audio amplifier is the terminal of whole sound system, and its effect is that audio electric energy is converted into corresponding acoustic energy, and its spoke
Space is mapped to go.
It is the extremely important part of sound system, because it is responsible for is transformed into acoustical signal for people's electric signal
Ear directly listens to so mission critical, and the sense of hearing that it will be directly with people is come into contacts with, and the sense of hearing of people be it is very sensitive,
And there is very strong resolving ability to the tone color of complex sound.
Because human ear is exactly to evaluate the fine or not most important standard of a sound system sound quality to the subjective feeling of sound, because
This, it is believed that the performance height of audio amplifier is to play key effect to the playing quality of a sound system.
Like that carrying with a storage battery audio amplifier plays music during people's outdoor activities at present.Traditional mobile storage battery audio amplifier
Storage battery is all mounted in the inside of audio amplifier, it is desirable to uses for a long time, must just change the big storage battery of lastblock, big storage battery in general
Weight is all heavier, causes the movement of storage battery audio amplifier or charging all convenient, therefore, proposing a kind of LED lights movable type storage battery
Audio amplifier.

The problem of middle proposition.
To achieve the above object, the utility model provides following technical scheme：A kind of LED lights movable type storage battery audio amplifier,
Including base and variable-frequency motor, the top surface of the base is installed with bearing block, the inside of the bearing block and screw mandrel
One end drive connection, the left end of the other end of the screw mandrel and reductor is connected, the output shaft of the variable-frequency motor with
Speed reducer drive connects, and the screw mandrel is threadedly coupled with rotating nut, and the top of the rotating nut passes through bolt and neck
Bottom is fixedly connected, and the both sides of the neck slidably connect guide rail, and the inside of the neck is connected with audio amplifier by threaded rod
Body.
Preferably, the leading portion of the speaker body is provided with Air Filter.
Preferably, the outer end of the threaded rod is fixedly connected with hand and twists bar, and the quantity of the threaded rod must not be less than four,
And threaded rod is equidistant linear distribution.
Preferably, the bottom of the variable-frequency motor is provided with spring-rubber pad.
Preferably, the bottom four corners of the base are symmetrically provided with universal wheel.
Compared with prior art, the beneficial effects of the utility model are：The utility model is simple in construction, easy to operate, leads to
Cross the operating of startup variable-frequency motor so that reductor rotates so that screw mandrel rotates, so that rotating nut left and right on screw mandrel is sliding
It is dynamic, so that neck can horizontally slip in the inside of guide rail, bar is twisted by hand and tightens threaded rod, is easy to consolidate speaker body
Fixed, by the stability of speaker body, cost is low, easy to remove, is adapted to promote.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
