For sounding；The sounding monomer 3 surrounds back cavity 92 jointly with the lower cover 1 and the upper cover 2, for improving frequency acoustic
Energy.I.e. the receiving space 9 is separated into the ante-chamber 91 and the back cavity 92 by the sounding monomer 3.
Specifically, in present embodiment, the retaining wall 4 extends from the upper cover 2 to 1 direction of the lower cover and is connected to institute
State lower cover 1.In present embodiment, the retaining wall 4 forms fixing seal with the lower cover 1 by ultrasonic welding process.Retaining wall 4
Back cavity 92 is separated into the first back cavity 921 and the second back cavity 922.
The wall 5 is arranged with the sounding monomer 5 interval, and wall 5 extends to first back cavity by the upper cover 2
In 921, the wall 5 surrounds opening 920 with the retaining wall 4；Be open lower cover 1 described in 920 faces.The breathable barrier 7 is solid
Surely it is covered on the opening 920.In present embodiment, this breathable barrier 7 of institute is formed solid by hot melting way and the wall 5
Fixed sealing.The breathable barrier 7 encloses with the wall 5 and the retaining wall 4 and sets to form sound absorption cavity 9210, the sound absorption cavity 9210
It is connected to first back cavity 921 through the breathable barrier 7.Breathable barrier 7 is arranged with the interval of the lower cover 1.Sound absorption cavity
Filling sound-absorbing particle 20 in 9210
The retaining wall 4 surrounds the second back cavity 922 for serving as the virtual operatic tunes jointly with the upper cover 2 and the lower cover 1.It is i.e. logical
It crosses and fills sound-absorbing particle (not shown) into second back cavity 922, second back cavity 922 is made to form D-BASS Virtual Sounds
Chamber.Above structure so that the formation of second back cavity 922 is not limited by the planform of the loudspeaker 100, can be by institute
It states in the second back cavity 922 and fills up acoustical cotton 10, increase the setting of its volumetric spaces to the greatest extent.
The wall 5 surrounds with the upper cover 2, the breathable barrier 7 and the retaining wall 4 and serves as the virtual operatic tunes jointly
And with first back cavity 921 in the sound absorption cavity 9210 of air communication.I.e. by filling sound-absorbing into the sound absorption cavity 9210
Grain 20 makes the sound absorption cavity 9210 form the virtual operatic tunes of D-BASS.Above structure makes the sound absorption cavity 9210 not have to additional increase
Mold is added to form exposed structure, simple in structure, production cost is low.
The loudspeaker enclosure 100 irregular shape substantially and second back cavity 922 substantially, fill
Divide and other space utilizations of second back cavity 922 are formed into the virtual operatic tunes, effectively increases the volume of the virtual operatic tunes, i.e., greatly
The acoustical behavior of the loudspeaker enclosure 100 of the improvement of degree.
In present embodiment, second back cavity 922 is located at the separate sounding monomer 3 of the sound absorption cavity 9210
Side.Described in being filled in the one end (i.e. second back cavity 922 in) of the sound absorption cavity 9210 far from the sounding monomer 3
10 structure of acoustical cotton rather than sound-absorbing particle 20.
It should be noted that：It is so-called in air communication be the guidance sound absorption cavity 9210 by the breathable barrier 7 with
First back cavity, 921 only mutual air circulation, other objects cannot mutually enter.
In present embodiment, the volume of the sound absorption cavity 9210 is 1.5 times of the volume of second back cavity 922, i.e. institute
State sound-absorbing particle 20 loading account for the acoustical cotton 10 and the sound-absorbing particle 20 total volume 60%.Aforementioned proportion is filled out
It fills so that the resonant frequency of the loudspeaker enclosure 100 effectively reduces.
The setting of the position of above-mentioned sound absorption cavity 9210 and second back cavity 922 so that the loudspeaker enclosure 100 it is entire
When the cavity 9210 and 922 of sound-absorbing is in sleeve configuration, pass through the filling acoustical cotton 10 replacement sound-absorbing in the sound absorption cavity 9210
Kernel structure more effectively improves the frequency acoustic performance of the loudspeaker enclosure 100.
In addition, the structure substitutes sound-absorbing grain structure in second back cavity 922 by filling the acoustical cotton 10, it can
92 standing wave of back cavity is inhibited to improve acoustical behavior to eliminate sound pressure level curve intermediate frequency paddy.
In present embodiment, more preferably, the upper cover 2, the retaining wall 4 and the wall 5 are an integral molding structure, certainly
Or separate structure assembly is fixed.
The intercommunicating pore 6 is arranged through the retaining wall 4 and second back cavity 922 is made to be connected to the sound absorption cavity 9210,
The air and sound of i.e. described second back cavity 922 and the sound absorption cavity 9210 mutually circulate.
The volume of the virtual operatic tunes is served as in the above structure energy high degree increase of the loudspeaker 100 of the present invention, to drop
Low resonant frequency simultaneously promotes low frequency sensitivity.
In present embodiment, second back cavity 922 is located at separate first back cavity 921 of the sound absorption cavity 9210
Side, which can realize in the whole powder fillings of 922 tail end of the second back cavity (i.e. the second back cavity 922), and back cavity 92 can be inhibited to stay
Wave improves acoustical behavior to eliminate sound pressure level curve intermediate frequency paddy.
In present embodiment, the intercommunicating pore 6 is formed by oblique top moulding process, and the intercommunicating pore 6 is rectangle.Certainly,
Its shape is without being limited thereto or other shapes, such as circle.
More preferably, in present embodiment, the breathable barrier 7 is screen cloth, its is without being limited thereto certainly, as long as institute can be isolated
It states sound-absorbing particle and enters first back cavity 921 and the entrant sound that can breathe freely.
The filling hole 8 is arranged through the upper cover 2, and the filling hole 8 is connected to the sound absorption cavity 9210, the sound-absorbing
Particle pours into the sound absorption cavity 9210 by the filling hole 8.
After sound enters second back cavity 922 and the sound absorption cavity 9210 by the first back cavity 921, successively pass through the suction
Sound particle 20 and the acoustical cotton 10 increase its transmission path, the audio performance for improving the loudspeaker enclosure 100, especially
Frequency acoustic performance.Specifically, in present embodiment, the sound-absorbing particle 20 is dust or zeolite granular etc..
Compared with the relevant technologies, loudspeaker enclosure of the invention is added from the upper cover to the lower cover side in the rear by intracavitary
The retaining wall to extension and the wall are surrounded by the retaining wall and the upper cover and the lower cover for serving as Virtual Sound
Second back cavity of chamber, second back cavity are not limited by the structure of loudspeaker enclosure；The wall and the upper cover, described simultaneously
Air bound off member and the retaining wall surround jointly serve as the virtual operatic tunes and with first back cavity be in air communication sound absorption cavity, institute
It is i.e. plastic woth no need to increase the mould structure of client to state sound absorption cavity, simple in structure, saved production cost and effective increased
The volume of the virtual operatic tunes；Acoustical cotton effectively reduces F0 with the cooperation filling of sound-absorbing particle simultaneously, which realizes described virtual
The operatic tunes individually maximizes, and effectively improves the frequency acoustic performance of the loudspeaker enclosure.
Above-described is only embodiments of the present invention, it should be noted here that for those of ordinary skill in the art
For, without departing from the concept of the premise of the invention, improvement can also be made, but these belong to the protection model of the present invention
It encloses.
