[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 Fig. 1-5 simultaneously, the utility model provides a kind of loudspeaker enclosure 100, including shell 1, sounding monomer 2, folder Wall 3 and breathable barrier 4.

The shell 1 has accommodating space 10, and the shell 1 can be structure as a whole, or separate structure, for example, The shell 1 merges the upper cover 12 for surrounding the accommodating space 10 jointly including lower cover 11, described cover with the lower cover 11.

The sounding monomer 2 is contained in the accommodating space 10 of the shell 1, and the sounding monomer 2 is by institute It states accommodating space 10 and is separated into ante-chamber 5 and back cavity 6.In present embodiment, the sounding monomer 2 is arranged with the upper cover 12 interval The ante-chamber 5 is surrounded jointly；The sounding monomer 2 surrounds the back cavity 6 with the upper cover 12 and the lower cover 11 jointly.It is described Back cavity 6 is used to improve the frequency acoustic performance of the loudspeaker enclosure 100.

The double wall 3 is extended by the inside of the shell 1.In present embodiment, the double wall 3 is by the upper cover 12 Extend to 11 direction of lower cover and is connected to the lower cover 11.

The peripheral part fixed clamp of the breathable barrier 4 in the double wall 3 and with the double wall 3 jointly by the back cavity 6 are divided into the first back cavity 61 and the second back cavity 62 being connected.In present embodiment, after first back cavity 61 and described second The connection of chamber 62 refers to the two air communication.The sounding monomer 2 is located at first back cavity 61, filling in second back cavity 62 Sound-absorbing particle (not shown) is used to form the virtual operatic tunes (i.e. the D-Bass operatic tunes), to improve frequency acoustic performance, it is described it is ventilative every The sound-absorbing particle is packaged in second back cavity 62 by off member 4.

The breathable barrier 4 includes middle part 42 and the peripheral part 41 extended to form by the periphery of the middle part 42, The middle part 42 is equipped with the ventilating structure (not shown) through thereon, and the peripheral part 41, which plugs, is fixed on the double wall 3.

The breathable barrier 4 is made of stainless steel material, and the peripheral part 41 and the relevant technologies thereon uses plastics The back cavity channel of bracket ratio, formation is bigger, facilitates the acoustical behavior for promoting loudspeaker enclosure 100.

The middle part 42 is equipped with the ventilating structure through thereon, and the ventilating structure includes multiple through through-hole thereon And multiple through-holes are arranged in paliform.

The ventilating structure is made of etching or laser grooving technique, which can expand sound chamber channel, promote product Acoustical behavior；With attachment mesh technique ratio before, patch mesh process is eliminated, technique has been simplified, has been conducive to mass production.

Certainly, the generation type of the ventilating structure is not one kind, can also first be etched by the breathable barrier Between step, then form the ventilating structure through laser treatment, generated effect is consistent.

More preferably, 42 surface indentation of middle part forms groove, and multiple through-holes are arranged through the groove.

The width of the peripheral part 41 is 0.3mm, and the space of the back cavity 6 can be greatlyd improve under the structure, and optimization produces The acoustical behavior of product.

Compared with the relevant technologies, the breathable barrier 4 of the loudspeaker enclosure 100 of the utility model includes 42 He of middle part The peripheral part 41 extended to form by the periphery of the middle part 42, the middle part 42 are equipped with the ventilating structure through thereon, institute Stating breathable barrier 4 is stainless steel material, and the peripheral part 41, which plugs, is fixed on the double wall 3, and it is logical which expands back cavity Road improves the acoustical behavior of product；It is structure as a whole with patch mesh ratio, the breathable barrier bracket before, eliminates patch The process for filling mesh, improves production.

Above-described is only the embodiments of the present invention, it should be noted here that for the ordinary skill of this field For personnel, without departing from the concept of the present invention, improvement can also be made, but these belong to it is practical Novel protection scope.
