The loudspeaker enclosure further comprises a second holder 3 made of plastic inside the rear sound chamber 102. The second bracket 3 is annular. The second bracket 3 is fixed on one side of the first bracket 14 close to the rear cover 12, and the second bracket 3 surrounds the circumference side of the sounding unit 2 and forms a seal.
The first bracket 14 and the second bracket 3 may be manufactured and fixed separately, but not limited to this, and the first bracket 14 and the second bracket 3 are integrally injection molded in this embodiment, which makes the manufacturing of the speaker box 100 simpler and the assembly of the speaker box 100 easier.
To further improve the low frequency acoustic performance of the loudspeaker element 100, the loudspeaker enclosure 100 further comprises a gas permeable barrier 4 arranged inside the housing 1.
The ventilation spacer 4 is fixed to the second bracket 3 and separates the sound generating unit 2 from the rear sound chamber 102, so that the rear sound chamber 102 can be filled with sound absorbing material.
Specifically, the ventilation spacer 4 includes a spacer body 41 facing the rear cover 12 at a distance and attached to the sounding unit 2, and a spacer extension 42 extending from the periphery of the spacer body 41 in a direction of the second bracket 3.

To further increase the volume of the rear acoustic chamber 102, such that the acoustic performance of the loudspeaker enclosure 100 is improved, may be achieved by the structure of the support 3. The ring 212 has an arc-shaped structure that is concave toward the rear cover 12. The concave shape of the folded ring portion 212 is beneficial to avoiding the first bracket 14, and extends toward the folded ring portion 212 through the first bracket 14 and is fixed to the front cover 11, so that the volume of the rear acoustic chamber 102 is increased, which will be described by way of another embodiment.
In another embodiment, the structure of the first bracket is used to describe how to increase the volume of the rear acoustic chamber 102. Referring to fig. 6, fig. 6 is a cross-sectional view of another embodiment of the loudspeaker enclosure of fig. 3. The first bracket 31a includes a first bracket body 311a having a ring shape and being sealed and fixed around the periphery of the sounding body 2a, a first bracket supporting wall 312a having a ring shape and being bent and extended from the periphery of the inner side of the first bracket body 311a in the direction of the vibration part 211a, a first bracket fixing part 313a being bent and extended from one end of the first bracket supporting wall 312a away from the first bracket body 311a in the direction away from the rear cover 12a and being abutted and fixed to the front cover 11a, and a first bracket extending wall 314a being bent and extended from the first bracket body 311a in the direction of the sound outlet 13 a. The first bracket extension wall 314a is fixed to the front cover 11a in an abutting manner and communicates the sound outlet 13a with the front sound chamber 101 a. The sounding unit 2a is supported and fixed on the first bracket supporting wall 312a.
Since the first bracket supporting wall 312a is bent and extended from the peripheral edge of the inner side of the first bracket body 311a toward the vibration part 211a, the structure makes the position of the first bracket fixing part 313a fixed to the front cover 11a closer to the vibration part 211a with respect to the position of the first bracket body 311a, so that the position of the first bracket fixing part 313a moves toward the space of the front sound chamber 101a, so that the volume of the rear sound chamber 102a increases.
Specifically, the orthographic projection portion of the first bracket supporting wall 312a toward the sounding monomer 2a along the vibration direction of the diaphragm 21a falls into the folded ring portion 212 a. This structure allows the first bracket fixing portion 313a to be disposed at a position opposite to the hinge portion 212a, so that the position of the first bracket fixing portion 313a is moved toward the space of the front acoustic chamber 101a, so that the volume of the rear acoustic chamber 102a is increased. Of course, the present invention is not limited thereto, and the orthographic projection of the first bracket supporting wall 312a onto the sounding body 2a along the vibration direction of the diaphragm 21a may fall into the vibration portion 211a or the diaphragm fixing portion 213 a. The structure of this embodiment effectively increases the volume of the rear acoustic chamber 102 a.
In order to better fix the first bracket 31a to the front cover 11a, the speaker box of this embodiment further includes a first bracket reinforcing wall 315a bent from an end of the first bracket fixing portion 313a remote from the first bracket supporting wall 312a and fixed to the front cover 11 a. The orthographic projection of the first support reinforcement wall 315a to the sounding unit 2a along the vibration direction of the diaphragm 21a is completely located in the folded ring portion 212 a. Of course, without being limited thereto, it is also possible that the orthographic projection of the first bracket reinforcing wall 315a to the sound generating unit 2a along the vibration direction of the diaphragm 21a is entirely located in the vibration portion 211a or in the diaphragm fixing portion 213a, and the structure of this embodiment effectively increases the volume of the rear acoustic chamber 102 a.
In this embodiment, the speaker box 100 further includes a seal member 5 attached to the outside of the housing 1. The seal 5 is arranged around the sound outlet 13. This structure makes the setting make casing 1 and sealing member 5 structure form an organic whole, and the whole aesthetic measure of outward appearance is better.
In this embodiment, the speaker box 100 further includes a conductive terminal 6 for electrically connecting the sounding unit 2 to an external signal. The conductive terminals 6 penetrate the housing 1 and are partially exposed from the housing 1.
Compared with the related art, in the loudspeaker box, the front cover and the rear cover of the shell are made of metal materials, the annular first bracket made of the metal materials is fixed with the front cover and used for supporting and fixing the sounding monomer, in the structure, the metal first bracket is combined with the metal front cover, and the metal front cover is combined with the metal rear cover, so that the loudspeaker box can be designed to be thinner relative to the whole plastic shell structure on the premise of ensuring the structural strength of the shell, the volume of a cavity in the shell is greatly increased, the volume of a rear sound cavity enclosed by the sounding monomer and the shell is effectively increased, and the acoustic performance, particularly the low-frequency acoustic performance, of the loudspeaker box is improved.
