1 is two, and the two bass box units 1 are all identical physical arrangements.Two bass box units 1 are in the arrangement of the row of a line one, friendship
Mistake is set, and is fixedly connected with each other integral.The present embodiment is respectively arranged a cover plate of speaking in the both sides of combination array formula bass box
9, it is identical with the corresponding vibrating diaphragm shape of second bass radiator 4 and the vibrating diaphragm shape of woofer 2 on cover plate 9 of each speaking, it
Between the shape of the air gap 5 that is formed it is also identical.Woofer 2 in two bass box units 1 of the present embodiment
What vibrating diaphragm was conically shaped, correspondingly, the part corresponding with the vibrating diaphragm of woofer 2 is also cone on cover plate 9 of speaking,
Other positions are tabular, and it is also cone to speak the air gap 5 formed between cover plate 9 and the vibrating diaphragm of woofer 2,
Gap is 9mm.Remaining is identical with embodiment 11.
Embodiment 13
As shown in Figure 13 A, Figure 13 B, the present embodiment and the difference of embodiment nine are：The each bass box unit of the present embodiment
The place tank wall of 1 medium and low spectrum loudspeaker 2 is vertical with the first bass radiator 3, the place tank wall of the second bass radiator 4.Remaining with
Embodiment nine is identical.
Operation principle of the present utility model is：
When the output of audio low frequency power puts on each woofer 2, woofer unit vibrating diaphragm produces vibration,
Realize that electroacoustic is changed.When each woofer unit vibrating diaphragm is to the bass box unit for being provided with first and second bass radiator 3,4
During 1 internal vibration, the air in bass box unit 1 is just have compressed, because bass box unit 1 is closed, air bullet will be produced
Atmospheric pressure superatmospheric in spring effect, such bass box unit 1 is strong, just drives shaking for first and second bass radiator 3,4
Film vibrates to outside bass box unit 1 simultaneously.When each woofer unit vibrating diaphragm of woofer 2 is to bass box unit 1
During outer vibration, the air spring release in the bass box unit 1 compressed, so as to produce vibrating diaphragm restoring force, this restoring force is just
The vibrating diaphragm of boosting woofer 2, makes the pressure in bass box unit 1 further reduce, so that the pressure in bass box unit 1
It is strong further below atmospheric pressure so that first and second bass radiator 3,4 is simultaneously to the internal vibration of bass box unit 1, thus
Vibrating diaphragm area has not only been increased considerably, while making amplitude also increase, has been greatly enhanced the bass sound wave of generation, while again
Independent of tank-volumes.And whole combination array formula bass box is made up of multiple bass box units 1, these bass box units 1
It is common to produce low-frequency sound wave and complete to be superimposed in acoustic space, whole bass is further lifted again.In addition, in combination battle array
The air gap 5 is provided with column bass box, so as to form aeroacoustics air cushion, is produced by first and second bass radiator 3,4
Information, which flows through this aeroacoustics air cushion, further to be strengthened；Further, (i.e. in combination above the vibrating diaphragm of bass box unit 1
Every side external surface of array bass box) cover plate 9 of speaking is provided with, another bass acoustic air cushion is formed again, makes bass sound wave
Further enhance, thus shaken with very little volume casing, the bass of thick and heavy high resilience.
Further, due to the reaction force of the air spring generation in bass box unit 1, making the voice coil loudspeaker voice coil position of woofer 2
Move and reduce, reduce electroacoustic slewing distortion.And whole combination array air-cushion type bass box is made up of multiple woofers 2, no
But overall audio amplifier power is increased, while the distortion factor is reduced, reliability is improved.Due to being correspondingly arranged the radiation of first and second bass
Device 3,4, when realizing electroacoustic conversion, symmetric vibration and amplitude is equal, and direction of vibration greatly disappears on the contrary, vibration force is offset
Except the vibration and displacement of casing.
Combination array formula bass box of the present utility model is also known as subwoofer, is made up of multiple bass box units 1, each bass
Box unit 1 again be provided with corresponding first and second bass radiator 3,4, between bass box unit 1 be provided with acoustics air cushion, and
Second acoustics air cushion is provided between bass box unit 1 and cover plate 9 of speaking, not only greatly reduces whole bass box volume, together
When make bass it is more thick and heavy, shock, distortion is smaller, dive is deeper.
