It includes the box platform, the built -in digital power amplifier module of integration that is equipped with of box platform, and the panel of box platform is made up and is equipped with the dustproof radiator -grid of a plurality of, in the box platform, the below that is located one of them dustproof radiator -grid be provided with one with the digital power amplifier module electric connection's of integration radiator fan. The utility model discloses a radiator fan and its with the mating reaction of dustproof radiator -grid under, not only can strengthen the radiating effect of whole audio amplifier inner space, also can play dustproofly through dustproof radiator -grid moreover and fall the effect of making an uproar, simultaneously, dustproof radiator -grid adopts detachable structural style, also is favorable to the user to dismantle, wash and maintain, its simple structure is compact, has very strong practical value and market spreading value.
Description
Technical field
The utility model relates to electroacoustic device technical field, the quick detachable ventilated net device of especially a kind of active audio amplifier power amplifier.
Background technology
Known, active audio amplifier, also known as active audio amplifier, is that power amplifier is made in audio amplifier inside by one, can directly be connected with source of sound and the audio amplifier normally worked.Existing active audio amplifier is due to the restriction by structure and function, cause the following problem of its ubiquity: the structure or the fitting designs that 1, play ventilation and heat function are very unreasonable, not only useful life of grievous injury audio amplifier and result of use, and too increase the use and maintenance cost of user; 2, complex structure, Installation and Debugging are very inconvenient; 3, existing active audio amplifier generally adopts category-A power amplifier (i.e. class a audio power amplifier) or category-B power amplifier (i.e. Class B power amplifier), when above-mentioned power amplifier is arranged in audio amplifier, need audio amplifier to have enough large volume to assemble, also substantially increase the weight of audio amplifier simultaneously.
Therefore, be necessary to propose improvement project to existing active audio amplifier, to optimize its structure and performance to greatest extent, meet the actual user demand of user.
Utility model content
For above-mentioned the deficiencies in the prior art, the purpose of this utility model be to provide a kind of simple and compact for structure, result of ventilating heat dissipation significantly, the use and maintenance quick detachable ventilated net device of active audio amplifier power amplifier easily.
To achieve these goals, the utility model adopts following technical scheme:
The quick detachable ventilated net device of a kind of active audio amplifier power amplifier, it comprises casing platform, integrated digital power amplifier module is equiped with in described casing platform, the panel of described casing platform is equiped with several dust-proof radiating nets, described casing platform below that is interior, that be positioned at one of them dust-proof radiating net is provided with a radiator fan be electrically connected with integrated digital power amplifier module.
Preferably, described dust-proof radiating net comprises dust suction cotton and dust cap, described casing platform offers heat radiation air port, and described dust cap is fixed by several connectors cotton for dust suction and be covered on heat radiation air port.
Owing to have employed such scheme, the utility model, by radiator fan and under the mating reaction of itself and dust-proof radiating net, not only can strengthen the radiating effect of whole audio amplifier inner space, and also can play effect that is dust-proof and noise reduction by dust-proof radiating net; Meanwhile, dust-proof radiating net adopts dismountable version, is also conducive to user and carries out dismantling, clean and safeguarding; It is simple and compact for structure, has very strong practical value and market popularization value.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.
As shown in Figure 1, the quick detachable ventilated net device of a kind of active audio amplifier power amplifier that the utility model embodiment provides, it comprises casing platform 1, integrated digital power amplifier module (not shown) is equiped with in casing platform 1, the panel of casing platform 1 is equiped with several dust-proof radiating nets a, meanwhile, in casing platform 1, the below that is positioned at one of them dust-proof radiating net a is provided with a radiator fan 2 be electrically connected with integrated digital power amplifier module.So, by under the mating reaction of radiator fan 2 and itself and dust-proof radiating net a, not only can strengthen the radiating effect of whole audio amplifier inner space, and also can play effect that is dust-proof and noise reduction by dust-proof radiating net a.
For optimizing the structure of whole audio amplifier further, ensure that it is functional, reduce the use and maintenance cost of user to greatest extent simultaneously, the dust-proof radiating net a of the present embodiment comprises dust suction cotton 3 and dust cap 4, casing platform 1 offers heat radiation air port 5, thus dust cap 4 fix by several connectors 6 (as screw or screw etc.) cotton for dust suction 3 and is covered on and dispels the heat on air port 5.With this, when user is according to the service condition of audio amplifier, can regular dismounting dust cap 4 and dust suction cotton 3, to clean both or to change, be very easy to maintenance and the use of audio amplifier.
In addition, the integrated digital power amplifier module of the present embodiment can be formed by integral type PFC power supply and with the D class power amplifier that integral type PFC power supply is electrically connected, so by adopting D class power amplifier to replace category-A power amplifier in conventional active audio amplifier or category-B power amplifier, and coordinate integral type PFC power supply, the volume and weight of whole audio amplifier can be reduced significantly, be convenient to the assembling of whole audio amplifier, debug and install and use.
The foregoing is only preferred embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model specification and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
