Abstract
The utility model relates to a kind of active automotive seat bass box with two passive bass radiator, comprise casing, the cavity volume that this casing is made up of casing lower casing and casing upper casing, PCBA circuit board and active loudspeaker unit is provided with successively from below to up in this cavity volume, this PCBA board includes audio-frequency power amplifier, this audio-frequency power amplifier and this active loudspeaker unit are electrically connected, this casing upper casing covers this active loudspeaker unit and is connected with casing lower casing is airtight, is also provided with passive bass radiating element in these active loudspeaker unit both sides.The above-mentioned active automotive seat bass box with two passive bass radiator, has the disturbance eliminating casing air-flow, the swept area increasing bass and radiation dynamics, to reach the advantage of multi-faceted enhancing bass expression effect.
Description
Technical field
The utility model relates to a kind of audio amplifier, especially a kind of active automotive seat bass box with two passive bass radiator.
Background technology
Existing automotive seat bass box is pure closed box, and thickness is thin, and volume is little, is unfavorable for the dive of initiatively bass unit, is unfavorable for the design and installation of phase-reversing tube.Pure closed box have impact on the efficiency of audio amplifier, and its bass swept area is also not enough.
Utility model content
In view of above-mentioned condition, be necessary to provide a kind of frequency range, swept area, the radiation dynamics that can increase bass, to reach the audio amplifier of multi-faceted enhancing bass expression effect.
For solving the problems of the technologies described above, a kind of active automotive seat bass box with two passive bass radiator is provided, comprise casing, the cavity volume that this casing is made up of casing lower casing and casing upper casing, PCBA circuit board and active loudspeaker unit is provided with successively from below to up in this cavity volume, this PCBA board includes audio-frequency power amplifier, this audio-frequency power amplifier and this active loudspeaker unit are electrically connected, this casing upper casing covers this active loudspeaker unit and is connected with casing lower casing is airtight, is also provided with passive bass radiating element in these active loudspeaker unit both sides.
This passive bass radiating element is two, is located at the both sides below this active loudspeaker unit respectively.
The above-mentioned active automotive seat bass box with two passive bass radiator, two passive bass radiating element is applied on automotive seat bass box, phase-reversing tube can be replaced in order to regulate the tonequality of little closed box, make it have the performance of better bass, eliminate the disturbance of casing air-flow.Increase the band width of the swept area of bass and radiation dynamics in the lateral direction and bass response, to reach the effect that multi-faceted enhancing bass shows.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model with the active automotive seat bass box of two passive bass radiator.
Wherein: 12, casing lower casing; 14, casing upper casing; 20, active loudspeaker unit; 30, passive bass radiating element; 40, audio-frequency power amplifier.
Embodiment
Below in conjunction with drawings and Examples, the active automotive seat bass box with two passive bass radiator of the present utility model is described in further detail.
Refer to Fig. 1, a kind of active automotive seat bass box with two passive bass radiator of the utility model embodiment, comprise casing, the cavity volume that this casing is made up of casing lower casing 12 and casing upper casing 14, PCBA circuit board and active loudspeaker unit 20 is provided with successively from below to up in this cavity volume, this PCBA board includes audio-frequency power amplifier 40, this audio-frequency power amplifier 40 is electrically connected with this active loudspeaker unit 20, this casing upper casing 14 covers this active loudspeaker unit 20 and is connected with casing lower casing 12 is airtight, passive bass radiating element 30 is also provided with in these active loudspeaker unit 20 both sides.
This passive bass radiating element 30 is two, is located at the both sides below this active loudspeaker unit 20 respectively, is respectively the passive radiator in left and right, and the passive radiator in left and right forms an elastic oscillating system with the air in active loudspeaker unit and containment housing.Its Elastic is provided by the surround of passive bass radiating element 30 and the air be enclosed in casing, and the quality of vibrational system is made up of the cone of passive radiator and counterweight.Adjusting the passive counterweight of radiator elements 30 and the soft durometer of surround and elasticity makes the resonance frequency of passive radiator near active loudspeaker unit 20 acoustic pressure attenuation points, in audio amplifier initiatively in loudspeaker unit 20 pairs of casings air drive under carry out passive sounding, to reach the effect that low frequency extends.Below this active loudspeaker unit 20, both sides arrange passive bass radiating element 30 respectively, and the low frequency extension effect that two elastic oscillating systems of its composition produce is very good.
Two passive radiator is applied on automotive seat bass box, and phase-reversing tube can be replaced in order to regulate the tonequality of little closed box, makes it have the performance of better bass, eliminates the disturbance of casing air-flow.Increase the frequency range of bass, swept area and radiation dynamics in the lateral direction, to reach the effect of multi-faceted enhancing bass performance.
The above, it is only preferred embodiment of the present utility model, not any pro forma restriction is done to the utility model, although the utility model discloses as above with preferred embodiment, but and be not used to limit the utility model, any those skilled in the art, do not departing within the scope of technical solutions of the utility model, make a little change when the technology contents of above-mentioned announcement can be utilized or be modified to the Equivalent embodiments of equivalent variations, in every case be do not depart from technical solutions of the utility model content, according to any simple modification that technical spirit of the present utility model is done above embodiment, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
