[specific embodiment]
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describing, it is clear that described embodiment is only a part of the embodiment of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
All other embodiment obtained, fall within the protection scope of the utility model.
Please join shown in Fig. 1-3 simultaneously, the utility model provides a kind of loudspeaker enclosure 100, including upper cover 1, lower cover 2, hair
Sound monomer 3, retaining wall 4 and breathable barrier 5.
The upper cover 1 is opposite with the lower cover 2 and interval is arranged, and the lid of lower cover 2, which is set, is fixed on the upper cover 1 and common
Form accommodating space 10.
The upper cover 1 includes with the lower cover 2 upper cover ontology 11 disposed in parallel and by the periphery of the upper cover ontology 11
The support level portion 12 extended to 2 direction of lower cover, the periphery of the lower cover 2 bear against the support level portion 12 and are formed
Sealing is fixed.For example, the upper cover 1 and the lower cover 2 form sealing by ultrasonic bonding and fix, gluing can also be passed through certainly
Mode or other means is realized.
The lower cover 2 includes the first cover board 21, the second cover board 22 and connection first cover board 21 and second lid
The connecting plate 23 of plate 22.First cover board 21 is parallel to each other with second cover board 22 and is located at different two plane.
The sounding monomer 3 is contained in the accommodating space 10, and the sounding monomer 3 and the upper cover 1 surround ante-chamber
101, it is used for sounding.Specifically, the sounding monomer 3 forms the preceding operatic tunes 6, the accommodating space with the setting of the upper cover 1 interval
Sound channel 7 is led in interior formation, for example described led sound channel 7 and be formed in the upper cover 1.It is described lead sound channel 7 by the preceding operatic tunes 6 with
The external world is connected to and the ante-chamber 101 is collectively formed.And side vocal structure then can be achieved in the sound channel 7 of leading.The sounding list
Body 3, the lower cover 2 and the upper cover 1 surround back cavity 102 jointly, for improving frequency acoustic performance.
The retaining wall 4 is formed in the accommodating space 10, and in present embodiment, the retaining wall 4 is from the upper cover 1 to institute
2 direction of lower cover is stated to extend to form.
The back cavity 102 is divided into interconnected by the retaining wall 4 equipped with the through-hole 41 and the retaining wall 4 run through thereon
First back cavity 1021 and the second back cavity 1022, i.e., described first back cavity 1021 and second back cavity 1022 pass through the through-hole 41
It is interconnected.The sounding monomer 3 is located in first back cavity 1021, fills sound-absorbing particle in second back cavity 1022
(not shown), for example, the sound-absorbing particle is zeolite granular.
In present embodiment, first cover board 21 is fixed on the upper cover 1 and lid sets first back cavity 1021 completely,
Second cover board 22 is fixed on the upper cover 1 and lid sets second back cavity 1022, the connecting plate 23 and the gear completely
The setting of 4 face of wall.First cover board 21 is parallel to each other and is located in different two plane, described first with second cover board 22
Cover board 21, the connecting plate 23 and second cover board 22 are an integral molding structure.
Therefore, when three parts of the lower cover 2 are covered on institute's upper cover 1, it is only necessary to primary lid, which is set, can be completed assembly,
Sealing is formed by different welding manners again to fix, and not only saves assembly process, while reducing mold requirement and production
Assembly cost.
For example, first cover board 21 and second cover board 22 pass through ultrasonic bonding mode and 1 shape of upper cover
It is fixed at sealing.The connecting plate 23 is arranged with 4 face of retaining wall and the two forms sealing by ultrasonic bonding and fixes, from
And make first back cavity 1021 and second back cavity 1022 mutually isolated.Certainly, the connecting plate 23 and the retaining wall 4
Between can also set sealant (not shown) by filling out, made between the connecting plate 23 and the retaining wall 4 by the sealant
Sealing is formed, for example, the sealant is by the gluing glue-line formed or foam of filling etc., this is all feasible.
The breathable barrier 5, which is sticked, to be fixed on the retaining wall 4 and the through-hole 41 is completely covered.The breathable barrier
5 are packaged in the sound-absorbing particle in second back cavity 1022, so that second back cavity 1022 forms the virtual operatic tunes, thus
Propagation path of the sound wave in the space is increased, the frequency acoustic performance of the loudspeaker enclosure 100 is effectively improved.It needs
Bright, the function that the breathable barrier 5 is, which refers to, allows air to pass through mutually circulation, but other materials is prevented mutually to flow
It is logical.
More preferably, the breathable barrier 5 is attached at the side close to first back cavity 1021 of the retaining wall 4.It should
The position setting of structure increases the effective volume of second back cavity 1022, further improves frequency acoustic performance.
Compared with the relevant technologies, the retaining wall that the loudspeaker enclosure of the utility model is formed in the accommodating space is by institute
It states back cavity and is separated into the first back cavity and the second back cavity, first back cavity and second back cavity pass through the through-hole on the retaining wall
It is interconnected, the upper cover is set as including respectively corresponding and setting with first back cavity, the retaining wall, second back cavity respectively
First cover board, the connecting plate and second cover board set, and first cover board, the connecting plate and described
Two cover boards are structure as a whole, and first cover board and second cover board are fixed on the upper cover by ultrasonic bonding and are formed
Sealing, the connecting plate and the retaining wall, which are formed, to be sealed, because of first cover board, the connecting plate and second cover board setting
It is structure as a whole, effectively reduces assembly process when with upper cover fixing seal, reduce mold requirement and production assembly cost.
The above description is only the embodiments of the present invention, and therefore it does not limit the scope of the patent of the utility model, all
Equivalent structure or equivalent flow shift made based on the specification and figures of the utility model, is applied directly or indirectly in
Other relevant technical fields, are also included in the patent protection scope of the utility model.
