The upper cover 2 of lower cover 1, leads sound channel 4, sound-absorbing particle 5 and breathable barrier 6 at sounding monomer 3.
The upper cover 2 surrounds receiving space 10 jointly with the lower cover 1.The upper cover 2 and the lower cover 1 can be integrated knot
Structure.
In present embodiment, the upper cover 2 is equipped with close to the side of the lower cover 1 to the direction far from the lower cover 1
Be recessed the container 21 formed.
The fixation of sounding monomer 3 is contained in the receiving space 10.The sounding monomer 3 is spaced with the upper cover 2
It is arranged and encloses to form the preceding operatic tunes 7 jointly；The sounding monomer 3 surrounds back cavity 101 jointly with the upper cover 2 and the lower cover 1.
The sound channel 4 of leading is formed in the receiving space 10, specifically, the sound channel 4 of leading is formed on described
Lid 2.The sound channel 4 of leading can be also an integral molding structure with the upper cover 2.It is described lead sound channel 4 by the preceding operatic tunes 7 with it is outer
Boundary is connected to, and is used to form side vocal structure.
That is, in present embodiment, the receiving space 10 is separated into ante-chamber 102 and institute by the sounding monomer 3
State back cavity 101, wherein the ante-chamber 102 includes that the preceding operatic tunes 7 leads sound channel 4 with described, for speaking；The back cavity 101
Frequency acoustic performance for improving the loudspeaker enclosure 100.
The sound-absorbing particle 5 is contained in the ante-chamber 102 and is fixed on the inner wall of the upper cover 2.That is, the upper cover 2
Face described in ante-chamber 102 part, the sound-absorbing particle 5 is fixedly installed in inner wall.
In present embodiment, more preferably, the sound-absorbing particle 5 is fixed in the container 21 of the upper cover 2, to
It utmostly ensure that the spatial volume of the preceding operatic tunes 102, improve acoustical behavior.
The fixed form of the sound-absorbing particle 5 is unlimited, for example is fixed on the upper cover 2 by glue 8 (or adhesive tape) stickup
Inner wall.Using glue spraying mode or dispensing mode can be passed through when glue 8.
The setting of the sound-absorbing particle 5 makes the inner wall coarse of the ante-chamber 102, that is, increases the damping of the ante-chamber 102,
To reduce the distortion spike of 100 sounding of the loudspeaker enclosure, effectively inhibit harmonic distortion caused by sounding higher order resonances and
High-frequency noise, and then improve the acoustical behavior of the loudspeaker enclosure 100.
