Description
Technical field
The utility model relates to vehicle speaker technical field, particularly relates to the two 5 cun of vehicle-mounted bass active audio amplifiers of a kind of passive basin.
Background technology
At present, on market, major part is all wooden large volume active audio amplifier, installs and bring a lot of inconvenience in the space that automobile is limited, installation site is also restricted to a great extent, mostly can only be arranged in the boot of automobile, cause that music is unbalance not to be concentrated, how many senses of hearing has not good effect; Further, electronic section is as amplification mostly with Class-AB power-like amplifier.This vehicle-mounted bass active audio amplifier, all higher from being packaged into cost of transportation, operating efficiency is lower, does not reach the effect of environmental protection and energy saving.
Utility model content
The purpose of this utility model is to provide for the deficiencies in the prior art that a kind of volume is little, efficiency is high, the two 5 cun of vehicle-mounted bass active audio amplifiers of the passive basin of environmental protection and energy saving.
To achieve these goals, the utility model is by the following technical solutions:
The two 5 cun of vehicle-mounted bass active audio amplifiers of a kind of passive basin, comprise radiating seat, the top of described radiating seat is fixed with iron net, the bottom of described radiating seat is fixed with base plate, described radiating seat is the cuboid tubular of left and right sides opening, the top of described radiating seat offers two transversely arranged loudspeaker installing holes, 5 cun of bass horns are all installed in described two loudspeaker installing holes, the both-side opening of described radiating seat is provided with passive basin, passive basin seat, plastic cement side plate, described passive basin is installed on the opening of described radiating seat by described passive basin seat, described plastic cement side plate is fixed on the outside of described passive basin.
Wherein, in described radiating seat, function sealing frame is also installed.
Wherein, described iron is provided with inscription plate on the net.
Wherein, described radiating seat is made of aluminum.
Wherein, described base plate is fabricated from iron.
The utility model beneficial effect is: the utility model adopts two 5 cun of bass horns, thus efficiently solve volume in the past large, difficult problems such as being limited to is installed, arbitrarily can install below seat, can not occupy any confined space in car, sound field audio can be located better; And, amplified by two 5 cun of bass horns, the left and right sides arrange passive basin, make that the volume of audio amplifier is little, efficiency is high, environmental protection and energy saving.
Accompanying drawing explanation
Fig. 1 is stereogram of the present utility model.
Fig. 2 is exploded perspective view of the present utility model.
Comprise in fig. 1 and 2:
1---radiating seat, 2---iron net, 3---base plate, 4---5 cun of bass horns, 5---passive basin, 6---passive basin seat, 7---plastic cement side plate, 8---function sealing frame, 9---inscription plate.
Embodiment
In order to describe the technical solution of the utility model in detail, below in conjunction with the accompanying drawing of the utility model embodiment, clear, complete description is carried out to the technical scheme of the utility model embodiment.Obviously, described embodiment is a part of embodiment of the present utility model, instead of whole embodiments.Based on described embodiment of the present utility model, the every other embodiment that those of ordinary skill in the art obtain under without the need to the prerequisite of creative work, all belongs to the scope of the utility model protection.
Please refer to Fig. 1 and Fig. 2, the two 5 cun of vehicle-mounted bass active audio amplifiers of passive basin of the present utility model, comprise radiating seat 1, the top of radiating seat 1 is fixed with iron net 2, and the bottom of radiating seat 1 is fixed with base plate 3, and base plate 3 can be fabricated from iron.The cuboid tubular of radiating seat 1 in left and right sides opening, namely radiating seat 1 of the present utility model is simultaneously as the casing of audio amplifier, and radiating seat 1 can be made of aluminum.The top of radiating seat 1 offers two transversely arranged loudspeaker installing holes, 5 cun of bass horns 4 are all installed in two loudspeaker installing holes, the both-side opening of radiating seat 1 be provided with passive basin 5 (also known as, false loudspeaker, it is driven by the sound of loudspeaker back side radiant (sound wave), so its vibration is passive, therefore be passive basin), passive basin seat 6, plastic cement side plate 7, passive basin 5 is installed on the opening of radiating seat 1 by passive basin seat 6, and plastic cement side plate 7 is fixed on the outside of passive basin 5.In use, after connecting the DC12V power supply of automobile, Class_D power amplifier drives, input bass music signal, during the playback of bass music signal, make the loudspeaker drum paper of 5 cun of bass horns 4 move and produce air pressure, because audio amplifier of the present utility model has been hermetic, passive basin 5 expands outwardly under the condition being subject to air pressure, thus change the volume of audio amplifier inside, volume and tucket are pressed into ratio change, loudspeaker and audio amplifier are arranged in pairs or groups better, reaches the object that tone color is more interesting to listen to.
Preferably, be also provided with function sealing frame 8 in radiating seat 1, function sealing frame 8 may be used for placing wire, circuit board etc.; Iron net 2 is provided with inscription plate 9, inscription plate 9 may be used for identifying brand, mark etc.
In sum, the utility model adopts two 5 cun of bass horns 4, thus efficiently solve volume in the past large, difficult problems such as being limited to is installed, arbitrarily can install below seat, can not occupy any confined space in car, sound field audio can be located better; And, amplified by two 5 cun of bass horns 4, the left and right sides arranges passive basin 5, make that the volume of audio amplifier is little, efficiency is high, environmental protection and energy saving.
Finally should be noted that; above embodiment is only in order to illustrate the technical solution of the utility model; but not the restriction to the utility model protection range; although done to explain to the utility model with reference to preferred embodiment; those of ordinary skill in the art is to be understood that; the technical solution of the utility model is modified or equivalent replacement, all belong to protection range of the present utility model.
