Description
Technical field
The utility model relates to the loud speaker field, relates in particular a kind of loud speaker with dust reduction capability, and it can allow loud speaker keep better tonequality and have long useful life.
Background technology
Loud speaker is a kind of electroacoustic converting member, and it converts the sound signal of telecommunication to sound.In general, no matter be the loud speaker of which kind of particular type, loud speaker includes base, loam cake and the buzzing sheet between base and loam cake, this base links to each other with detachable upper cover dress formula, cover on being somebody's turn to do and offer several vocal holes, this sound signal of telecommunication can transform into the vibration of buzzing sheet, outwards propagates at last sound by air dielectric again.
But; in the use procedure of loud speaker, because traditional loud speaker do not arrange special proofing dust and protecting, thereby so that after loud speaker used of a specified duration; can be attached with dust and metal fillings above the buzzing sheet, have a strong impact on tonequality and the useful life of loud speaker.
In view of this, the inventor has this case to produce for the defects further investigation in the existing loud speaker then.
The utility model content
The purpose of this utility model is to provide a kind of loud speaker with dust reduction capability, to solve prior art after loud speaker has been used of a specified duration, can be attached with dust and metal fillings above the buzzing sheet, and then have a strong impact on the tonequality of loud speaker and the problem in useful life.
In order to reach above-mentioned purpose, solution of the present utility model is:
A kind of loud speaker with dust reduction capability comprises loam cake, base and the buzzing sheet between loam cake and base, and this loam cake links to each other with base is dismantled and assembled, covers on this also to be formed with several vocal holes; Wherein, this loud speaker also comprises Air Filter, and this Air Filter and covers all vocal holes in the loam cake between loam cake and buzzing sheet.
Further, this Air Filter is pasted at loam cake inner.
After adopting said structure, a kind of loud speaker with dust reduction capability that the utility model relates to, it is by being provided with Air Filter between loam cake and buzzing sheet, so this Air Filter can intercept dust between Air Filter and loam cake, namely guarantee can not be attached with dust and metal fillings on the buzzing sheet, thereby allow loud speaker can keep higher tonequality, and then greatly prolong the useful life of loud speaker.
Description of drawings
Fig. 1 is the three-dimensional exploded view that the utility model relates to a kind of loud speaker with dust reduction capability.
Among the figure:
Loam cake 1 connects cramp 11
Vocal hole 12 bases 2
Inner core 4 Air Filters 5.
Embodiment
In order further to explain the technical solution of the utility model, the utility model is elaborated below by specific embodiment.
As shown in Figure 1, a kind of loud speaker 100 with dust reduction capability that the utility model relates to, comprise loam cake 1, base 2 and the buzzing sheet 3 between loam cake 1 and base 2, certainly this loud speaker 100 also comprises the inner core 4 between loam cake 1 and base 2, this inner core 4 is rendered as various matched structures according to its work at present pattern, thereby makes buzzing sheet 3 vibration-generatings.
This loam cake 1 and 2 dismantled and assembled linking to each other of base particularly, are formed with several and connect cramp 11 on this loam cake 1, then be formed with Button Block 21 on this base 2, this connects cramp 11 and can link to each other with Button Block 21 fastenings, also is formed with several vocal holes 12 on this loam cake 1, and enable voice can send smoothly.
Improvements of the present utility model are: this loud speaker 100 also comprises Air Filter 5, and this Air Filter 5 and covers all vocal holes 12 in the loam cake 1 between loam cake 1 and buzzing sheet 3.Preferably, this Air Filter 5 is pasted in loam cake 1 inside, thereby on the one hand has characteristics easy to assembly, can also directly realize on the other hand the effect of preventing dust, good dustproof effect.
Like this, a kind of loud speaker 100 with dust reduction capability that the utility model relates to, it is by being provided with Air Filter 5 between loam cake 1 and buzzing sheet 3, so this Air Filter 5 can intercept dust between Air Filter 5 and loam cake 1, namely guarantee can not be attached with dust and metal fillings on the buzzing sheet 3, thereby allow loud speaker 100 can keep higher tonequality, and then greatly prolong the useful life of loud speaker 100.
Above-described embodiment and graphic and non-limiting product form of the present utility model and style, any person of an ordinary skill in the technical field all should be considered as not breaking away from patent category of the present utility model to its suitable variation or modification of doing.
