The utility model discloses an effectively utilize the broken space of discrete of TV set or other electronic equipment the inside to realize the increase volume, pass through the air compression of pipeline moreover after, the bass effect is better. Under the more and more littleer prerequisite of modern electronics electric appliances volume, more high -quality bass playback level can be sent to this technique in less volume.
Description
Technical field
The utility model belongs to technology for loudspeaker box field, is related to a kind of bass boosting sound box.
Background technology
Now television set and other electronic equipments enter the ultra-thin epoch so that tonequality worse and worse, particular without low frequency,
Sound that sound is very thin so that consumer cannot get due audio-visual appreciation and enjoy.Because its inner space is less, also
Other components and parts are installed so that television set or other electronic device spaces are discontinuous, there is the broken space in many places inside.Tradition
Technology for loudspeaker box cannot make full use of these discontinuous broken spaces.
Existing audio amplifier is all that woofer is mounted in same casing, it is impossible to realize the sound of space height and left and right
Field control, it is impossible to realize the perfect hearing effect of science.Existing monomer loudspeaker, due to not overcoming acoustic short circuit problem, institute
Almost do not have with low frequency, single loudspeaker are difficult to take into account senior middle school's low frequency, so sound is very dull, distortion is big, and effect is poor.
The existing phase inverted cabinet with simple casing sound chamber, effect is more better than monomer loudspeaker, and low frequency has got well one
A bit, distortion is somewhat better, and due to the size limitation of phase-reversing tube, so less efficient, low-frequency effect improves little.
Existing closed audio amplifier, distortion is relatively low, but due to not utilize loudspeaker back sound wave, so efficiency compared with
It is low, thank that vibration frequency is higher, low-frequency effect is not good.
The content of the invention
Technical problem：The utility model provides one kind can be suitable for using, effectively in incoherent little Space Product

Beneficial effect：The utility model compared with prior art, with advantages below：
Single-chamber body is adapted to be used in big space, Multicarity be applied to use in incoherent little Space Product, because
For many parts inside a product, often space is discontinuous.The utility model is by effectively utilizes television set or other electricity
Discontinuous broken space inside sub- equipment realizing increase volume, and after the air compression of pipeline, bass effect
Fruit is more preferably.On the premise of hyundai electronicses electric equipment products volume is less and less, the technology can send in less volume compared with
High-quality replaying bass level.
Separate active chamber and passive chamber, it is to avoid mutual interference, it is especially clear when making their playbacks, while
Changing tradition needs huge volume to can be only achieved required acoustical quality, effectively reduces audio amplifier volume.
Description of the drawings
Fig. 1 is the utility model structural representation.
Specific embodiment
The utility model is further described with reference to embodiment and Figure of description.
Many casing bass boosting sound boxes of the present utility model, as shown in figure 1, audio amplifier of the present utility model belongs to by splitting
Multiple airtight cavities are constituted, respectively active chamber 1 and passive chamber 2, and the two is connected by air delivery duct 3.Set in active chamber 1
Active loudspeaker unit 4 is equipped with, passive Caloris Basin 5 is provided with passive chamber 2.The cone of the main loudspeaker of active loudspeaker unit 4
Vibrations, drive air flow in the casing of active chamber 1, and through air delivery duct 3 passive chamber 2 is transferred to, and enter from cavity in air
When entering in narrower pipeline, air can be compressed, and produce more preferable bass effect.Passive chamber 2 as active chamber 1 acoustic load,
The volume in passive chamber 2 is equivalent to the casing total measurement (volume) that increased whole bass boosting sound box system, so a whole set of sound box system
Resonant frequency Fb extends lower, and in hgher efficiency, bass is more preferable.When the cone of active loudspeaker unit 4 is moved out, in outside
In the presence of atmospheric pressure, passive Caloris Basin 5 is inwardly moved under external pressure effect, promotes the air sounding outside case；Work as master
When the cone of dynamic loudspeaker unit 4 is inwardly moved, passive Caloris Basin 5 is moved out under external pressure effect, so as to drive
Air pulsation sounding.
In embodiment of the present utility model, the size bore adaptability of active loudspeaker unit 4 is wider, in general adopts
It is small-bore（Less than 8 inches）Active loudspeaker, for the audio amplifier of small size, technique effect is more preferably.The horizontal stroke of air delivery duct 3
Cross sectional shape can be circle, ellipse, triangle, rectangle, square, polygon or other shapes, due to round and smooth
Impedance of the space to air it is relatively low, and wind noise is less prone to, therefore general from circular, oval, to reach more preferably
Audio.The shape in active chamber 1 and passive chamber 2 can be various.
In the utility model, loudspeaker unit unit 4 with can be various shapes, and active loudspeaker unit 4 can be with
It is mounted in the correct position in each face of the casing of active chamber 1.At least include an active chamber 1 and a passive chamber 2, or by
It is that multiple active chambers 1 and multiple passive chambers 2 are constituted, active chamber 1 connects with passive chamber 2 by the way that air delivery duct 3 is corresponding.Air
Transmission pipeline 3 can be one, or many, can connect on each face.When using an active chamber 1 and a quilt
During the scheme in dynamic chamber 2, both can be connected by an air delivery duct 3, when being limited due to audio amplifier physical condition, without reason
During the spatial arrangement thought, also can be connected by multiple air delivery ducts 3.
In the utility model, when being limited due to audio amplifier physical condition, without preferable spatial arrangement, and design requirement is less
Active cavity volume and during relatively large passive cavity volume, active chamber 1 can be adopted for one, passive chamber 2 is multiple side
Case, active chamber 1 is connected by the air delivery duct 3 being correspondingly arranged with each passive chamber 2.Now, air delivery duct 3 can be with
It is one, or multiple.
In the utility model, the scheme in multiple active chambers 1 and multiple passive chambers 2 can also be adopted, each active chamber 1 and passive
Chamber 2 is connected by the air delivery duct 3 being correspondingly arranged.
In the utility model, when being limited due to audio amplifier physical condition, without preferable spatial arrangement, and design requirement is larger
Active cavity volume and during relatively small passive cavity volume, in the case where ensureing that signal is consistent with phase place, can also include
Multiple active chambers 1, the scheme in a passive chamber 2, each active chamber 1 by the air delivery duct 3 that is correspondingly arranged with it is passive
Chamber 2 connects.Now, air delivery duct 3 can be one, or multiple.
In the utility model, passive Caloris Basin 5（It is commonly called as passive basin）Can be one, or multiple, passive radiation
Basin 5 can be arranged on the outer surface in passive chamber 2, to reach more preferable audio, but limit in audio amplifier physical condition, without preferable
When position is laid, it is also possible to which passive Caloris Basin 5 is embedded in passive chamber 2.
Above-described embodiment is only preferred embodiment of the present utility model, it should be pointed out that：It is common for the art
For technical staff, on the premise of without departing from the utility model principle, some improvement and equivalent can also be made, these
The utility model claim is improved and equivalent after technical scheme, each fall within protection model of the present utility model
Enclose.
