It closes and fixes.Certainly, the breathable barrier 42 may be to be integrally formed with the bracket 41.
The sound-absorbing is particles filled in the back cavity 102, for enhancing frequency acoustic performance.In present embodiment, institute
Sound-absorbing particle is stated to be located on the outside of the auxiliary leak 4, i.e., the described auxiliary leak 4 by the sound-absorbing particle be packaged in it is described after
In chamber 102 and the sound-absorbing particle is isolated with the leak 31, the leak 31 for avoiding the sounding monomer 3 is described
Sound-absorbing particle blocks and causes gas pressure leak unsmooth, while increasing the leakage space of the leak 31, and improving sounding can
By property.The sound-absorbing particle is packaged in the back cavity 102 by the auxiliary leak 4, is formed the virtual operatic tunes of D-BASS, is used for
The frequency acoustic performance of the loudspeaker enclosure 100 is improved, which can make the back cavity 102 realize complete filling structure, so that institute
It states the maximization of back cavity 102 to utilize, effectively increases frequency acoustic performance.In present embodiment, the sound-absorbing particle is zeolite
Grain.
Specifically, opening up the powder filling hole 21 being connected to the back cavity 102, the suction in the upper cover 2 in present embodiment
Sound particle is poured into the back cavity 102 by the powder filling hole 21, then the powder filling hole 21 is set closing by the lid of sealing cover 22.
Certainly, the powder filling hole 21 can also be opened in lower cover 1, this is also feasible.
Compared with the relevant technologies, the auxiliary with ventilation space is arranged loudspeaker enclosure of the invention in the back cavity and leaks
Portion makes the auxiliary leakage position in the side of the sounding monomer and the leak of the sounding monomer is completely covered, and makes
The leak is connected to the ventilation space, and the sound-absorbing particle is filled in the back cavity and is located at the auxiliary leak
Outside, the leakage area of the leak is increased by the auxiliary leak, avoids the leak quilt of the sounding monomer
The sound-absorbing particle blocks and causes gas pressure leak unsmooth, improves sounding reliability；Meanwhile by described auxiliary in the back cavity
Leak isolation is helped to realize complete filling structure, the filling amount of sound-absorbing particle is bigger, so that back cavity is effectively improved using maximization
The acoustical behavior of the loudspeaker enclosure.
