Description
Technical field
This utility model relates to sound system technical field, is specifically related to a kind of damping type audio amplifier.
Background technology
Audio amplifier is last in whole sound system flow process, is also a most important composition, and its playing quality is to whole
The impact of individual systematic function is very big, estimates according to professional person, and audio amplifier accounts for whole system to the contribution of whole sound system
More than 30%.Audio amplifier itself includes the quality of voice box casing, speaker and frequency divider, speaker and the frequency divider shadow to tonequality
Ring and account for 70%, and voice box casing accounts for 30% to the impact of tonequality.
Common sound-box device, after input audio signal, will produce sound by agitating air.When sound-box device is special
Not being the sound of subwoofer for playing bass when opening bigger, audio amplifier self also can produce strong vibrations, thus cause
Audio amplifier self produces and jumps or the displacement of left-right and front-back, so that the sound produced is impure.And this strong vibrations are also
Other article that may drive surrounding shake, thus damage these article of surrounding.Such as, it is placed on one when audio amplifier and computer
When rising, the vibrations of audio amplifier can make host computer also and then shake together, consequently, it is possible to the parts such as hard disk damaged in computer, mainboard
Deng.
Utility model content
The purpose of this utility model is the defect for prior art and deficiency, it is provided that a kind of simple in construction, design are closed
Reason, damping type audio amplifier easy to use.
For achieving the above object, the technical solution adopted in the utility model is: it comprises sound box, speaker, control
Panel, metallic plate, magnetic rubber, damping spring, balancing weight；Speaker it is provided with in described sound box, sound box
Upper surface is provided with control panel；The bottom of described sound box is provided with magnetic rubber, and the lower surface of magnetic rubber is arranged
Having metallic plate, the lower surface of metallic plate connects damping spring, and the lower end of damping spring is provided with balancing weight.
As preferably, described metallic plate is high rigid metal plate.
As preferably, the bottom of described balancing weight is provided with cushion.
During this utility model operation, at the special magnetic rubber of upper surface pressing of high rigid metal plate, magnetic rubber is straight
Connect and contact with sound box, it is achieved the efficient damping of sound box, and counterweight is set in damping spring lower end, increase stability.
After using said structure, what this utility model produced has the beneficial effect that a kind of damping type described in the utility model
Audio amplifier, good damping effect, the parts of apparatus such as computer around will not be damaged, this utility model has simple in construction, arranges conjunction
The advantages such as reason, cost of manufacture are low.
Accompanying drawing explanation
Fig. 1 is structure chart of the present utility model.
Description of reference numerals:
Sound box 1, speaker 2, control panel 3, metallic plate 4, magnetic rubber 5, damping spring 6, balancing weight 7, damping
Pad 8.
Detailed description of the invention
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, below will be to embodiment
Or the required accompanying drawing used is briefly described in description of the prior art, it should be apparent that, the accompanying drawing in describing below is only

Put, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
Referring to as it is shown in figure 1, this detailed description of the invention adopt the following technical scheme that it comprise sound box 1, speaker 2,
Control panel 3, metallic plate 4, magnetic rubber 5, damping spring 6, balancing weight 7；It is provided with speaker 2 in described sound box 1,
The upper surface of sound box 1 is provided with control panel 3；The bottom of described sound box 1 is provided with magnetic rubber 5, magnetic rubber
The lower surface of glue 5 is provided with metallic plate 4, and the lower surface of metallic plate 4 connects has damping spring 6, the lower end of damping spring 6 to be provided with
Balancing weight 7.
As preferably, described metallic plate 4 is high rigid metal plate.
As preferably, the bottom of described balancing weight 7 is provided with cushion 8.
During the operation of this detailed description of the invention, at the special magnetic rubber of upper surface pressing 5 of high rigid metal plate, by magnetic rubber
Glue 5 directly contacts with sound box 1, it is achieved the efficient damping of sound box 1, and arranges counterweight in damping spring 6 lower end, increases
Stability.
After using said structure, what this detailed description of the invention produced has the beneficial effect that described in this detailed description of the invention
Planting damping type audio amplifier, good damping effect, will not damage the parts of apparatus such as computer around, this detailed description of the invention has structure
Simply, the advantages such as reasonable, cost of manufacture is low are set.
Of the present utility model ultimate principle and principal character and of the present utility model advantage have more than been shown and described.This
Skilled person will appreciate that of industry, this utility model is not restricted to the described embodiments, and retouches in above-described embodiment and description
