Please refer to Fig. 1-2, the present invention provides a kind of loudspeaker enclosures 100, including shell 1, upper cover plate 2, sounding list
Body 3 leads sound channel 4 and gasket 5.
The upper cover plate 2 is covered on the shell 1 and forms receiving space 10, and the sounding monomer 3 is contained in the receipts
Hold in space 10.
Specifically, the shell 1 includes bottom wall 11, extends from the edge of the bottom wall 11 to 2 direction of the upper cover plate
Side wall 12, tilt from the bottom wall 11 to 2 direction of the upper cover plate extend and be connected to the upper cover plate 2 in hollow and annular
Wall extension 13 and the wall 14 extended from the bottom wall 11 to 2 direction of the upper cover plate.The wall extension 13 is by the receiving
Space 10 is divided into the first chamber 101 and the second chamber 102.
The bottom wall 11 includes ontology 111, through the ontology 111 and the through-hole that is oppositely arranged with the wall extension 13
It 112 and is fixed on the ontology 111 and covers and set the lower cover 113 of the through-hole 112.The setting of the through-hole 112 facilitates institute
State the installation of sounding monomer 3.
The sounding monomer 3 is assembled by the through-hole 112 and is supported in the separate upper cover plate 2 of the wall extension 13
First chamber point 101 is simultaneously divided into the preceding operatic tunes 1011 and the rear operatic tunes 1012 by side.
The side wall 12 is equipped with the outlet sound mouth 121 through thereon.
The wall extension 13 is in hollow and annular, is connected to the upper cover plate 2, the sounding monomer is supported in the extension
Interval is formed behind the side far from the upper cover plate 2 of wall 13 with the upper cover plate 2 to be arranged and surround the preceding operatic tunes jointly
1011；Surround the rear operatic tunes 1012 jointly with the lower cover 113 simultaneously.
The wall 14 is connected to the upper cover plate 2, and the wall 14 by the preceding operatic tunes 1011 extend to it is described go out
Sound mouth 121, to lead sound channel 4 described in formation.It is described lead sound channel 4 by the preceding operatic tunes 1011 be in communication with the outside and with it is described
Ante-chamber 20 is collectively formed in the preceding operatic tunes 1011, is used for sounding.
The wall extension 13 is equipped with through connection 131 thereon, the intercommunicating pore 131 will the operatic tunes 1012 afterwards with it is described
Second chamber 102 is connected to and back cavity 30, the frequency acoustic performance for improving the loudspeaker enclosure 100 is collectively formed.
The gasket 5 is located between the shell 1 and the upper cover plate 2, this upper cover plate 2 and the shell to make
Body 1 realizes fixing seal.In present embodiment, the gasket 5 is made of foam, is certainly not limited to this.
More preferably, the periphery bending of the upper cover plate 2 extends to form retaining wall 21, and the retaining wall 21 is equipped with through opening thereon
Mouth 22.The retaining wall 21, which is connected to, described lead sound channel 4 and the opening 22 is made to be arranged with 121 face of the outlet sound mouth.
In order to ensure sealing effect, in present embodiment, between the retaining wall 21 and the side wall 12 also described in setting
Gasket 5, and the gasket 5 is made to be arranged around the outlet sound mouth 121.
Above structure i.e. so that the preceding operatic tunes 1011 and it is described lead sound channel 4 all and be share the upper cover plate 2 and be used as it
Same side structure, that is to say, that the air-flow of the preceding operatic tunes 1011 along the upper cover plate 2 be circulated to always it is described lead sound channel 4,
For a horizontal flow direction, there is good flowing smoothly property, avoid the generation of noise.
When assembly, the sounding monomer 3 is first assembled to the wall extension 13 by the through-hole 112 of the bottom wall 11,
And make the two fixing seal.The lower cover 113 is covered on the through-hole 112 again and is fixed on the ontology 111, such as is logical
Dispensing mode is crossed to fix.At this point, the ante-chamber 20 and the back cavity 30 are in semi-open-type, not sealing state.Again by institute
State upper cover plate 2 and the shell 1 lid and set to form sealing and fix, for example, by the gasket 5 be attached at respectively the side wall 12,
One end of the close upper cover plate 2 of the wall 14 and the wall extension 13.Again with 2 secure bond of the upper cover plate.At this point,
The ante-chamber 20 and the back cavity 30 then realize separation and sealing state simultaneously.Above structure makes the preceding operatic tunes 1011 and institute
State and lead sound channel 4 and extended by the upper cover plate 2, i.e., the air-flow of the preceding operatic tunes 1011 can level flow through it is described lead sound channel 4,
So that the airflow of the ante-chamber is smooth, the acoustical behavior of loudspeaker enclosure 100 is effectively improved, avoids the production of noise
It is raw.
Compared with the relevant technologies, the shell of loudspeaker enclosure of the invention include bottom wall, from the edge of the bottom wall to
The side wall of the cover board direction extension tilts extension to the upper cover plate direction from the bottom wall and is connected to the upper cover plate
Wall extension in hollow and annular and wall from the bottom wall to the upper cover plate direction that extend from；The wall extension is by the shell
The receiving space of body is separated into the first chamber and the second chamber；Institute's bottom wall is equipped with sets the through-hole through the through-hole thereon with lid
The sounding monomer is assembled to the side far from the upper cover plate of the wall extension by lower cover by the through-hole, will be described
After upper cover plate assembly is connected to the shell so that first chamber is separated into the preceding operatic tunes and the rear operatic tunes by the sounding monomer,
What the wall then formed the connection preceding operatic tunes simultaneously leads sound channel, and the two forms ante-chamber.Above structure makes the preceding sound
Chamber and the sound channel of leading are extended by the upper cover plate, i.e., the air-flow of the described preceding operatic tunes can level flow through described in lead sound channel,
So that the airflow of the ante-chamber is smooth, the acoustical behavior of loudspeaker enclosure is effectively improved, avoids the generation of noise.
Example the above is only the implementation of the present invention is not intended to limit the scope of the invention, every to utilize this hair
Equivalent structure or equivalent flow shift made by bright specification and accompanying drawing content is applied directly or indirectly in other relevant skills
Art field, is included within the scope of the present invention.
