[0037] Example 1:

[0038] like Figures 1 - 6 As shown, the utility model discloses a loudspeaker assembly structure, comprising:

[0039] a first housing 1;

[0040] The second housing 2, the first housing 1 and the second housing 2 are sealed and assembled to form a first chamber 41 in the first housing 1 and the second housing 2; and,

[0041] The speaker 5 includes a third shell 3 and a speaker assembly 51. The speaker assembly 51 is installed on the third shell 3, and the speaker 5 is placed in the first cavity 41. Specifically, the first shell 1 and the third shell 3 are sealed and assembled to form a second cavity 42 in the first shell 1 and the third shell 3, and the speaker assembly 51 is arranged in the second cavity 42.

[0042] Therefore, 1. the first housing 1 and the second housing 2 are sealed together to form a first chamber 41 for mounting the speaker 5 therein, forming a first sealed structure. 2. The third housing 3 of the speaker 5 acts as a mounting member and is sealed together with the first housing 1 to form a second chamber 42 for mounting the speaker assembly 51 therein, forming a second sealed structure. In summary, this double sealing structure effectively protects the speaker assembly 51 from water.

[0043] In addition, the third housing 3 of the loudspeaker 5 is sealed and assembled with the first housing 1 , thereby reducing the number of parts. Moreover, since the loudspeaker 5 is a finished product, assembly is more convenient.

[0044] Specifically, the speaker assembly 51 includes a vibrating piece, a magnetic circuit structure, etc., and vibrates and produces sound by providing an alternating audio current signal.

[0045] Preferably, in this embodiment, sealant is applied between the first housing 1 and the second housing 2 for fixation and sealing; sealant is also applied between the first housing 1 and the third housing 3 for fixation and sealing, so that the first housing 1 and the second housing 2 are connected with high strength and have good sealing effect. Similarly, the first housing 1 and the third housing 3 are connected with high strength and have good sealing effect.

[0046] Wherein, a wire outlet hole 31 is provided through the third housing 3 in this embodiment, so that the part of the first chamber 41 independent of the second chamber 42 is communicated with the second chamber 42 through the wire outlet hole 31, so that the wire of the sound generating assembly 51 passes through the wire outlet hole 31 and exits from the second chamber 42 to the part of the first chamber 41 independent of the second chamber 42 to lead out the wire for electrical connection; in addition, the wire outlet hole 31 is sealed with sealant to prevent water from leaking at the wire outlet hole 31 and causing damage to the sound generating assembly 51 due to water entering the second chamber 42.

[0047] Wherein, the volume of the first chamber 41 is V1, and the volume of the second chamber 42 is V2. Preferably, 0.5V1 ≤ V2 < V1; so that the volume of the second chamber 42 is as close as possible to the volume of the first chamber 41.

[0048] Therefore, when the overall volume is constant, the first chamber 41 has a larger volume and has enough space for the installation and vibration of the sound generating assembly 51, making it easier to install and the vibration more complete, thus improving the sound quality.

[0049] Wherein, a first opposing surface 32 is provided on one side of the third housing 3 facing the second housing 2, and a second opposing surface 22 opposite to the first opposing surface 32 is provided in the second housing 2. The distance between the first opposing surface 32 and the second opposing surface 22 is s. Preferably, s ≤ 10 mm, so that the distance between the first opposing surface 32 and the second opposing surface 22 is reduced as much as possible to make the overall structure more compact.

[0050] Specifically, a first cavity 411 is provided in the first housing 1 in this embodiment, and a second cavity 412 is provided in the second housing 2. The first cavity 411 and the second cavity 412 are combined to form the first chamber 41; by dividing the first chamber 41 into two parts, the volume of the first cavity 411 is reduced, so that when the first housing 1 and the second housing 2 are opened, it is more convenient to assemble parts in the first cavity 411. In addition, the first housing 1 and the second housing 2 also have a certain volume, which is convenient for taking and assembling.

[0051] In other embodiments, the first chamber 41 is only provided on the first housing 1 or the second housing 2.

[0052] Specifically, a third cavity 421 is provided in the first cavity 411, and a fourth cavity 422 is provided in the third housing 3. The third cavity 421 and the fourth cavity 422 are combined to form a second chamber 42. This provides an installation space for the sound - producing component 51 through the fourth cavity 422, and the volume of the sound - producing component 51 extending out of the fourth cavity 422 is smaller, so that when the third housing 3 is installed on the first housing 1, it has a protective effect on the sound - producing component 51, while the third cavity 421 provides space for the sound - producing component 51 extending out of the fourth cavity 422 to prevent interference when the sound - producing component 51 is working.

[0053] In addition, the sound - producing component 51 can also be completely placed inside the fourth cavity 422.

[0054] Preferably, a part of the fourth cavity 422 is placed inside the first cavity 411, and a part extends out of the first cavity 411 and enters the second cavity 412, so that the fourth cavity 422 occupies as much of the first cavity 411 and the second cavity 412 as possible, making the overall structure more compact.

[0055] Among them, in this embodiment, an inner ring groove 11 is provided at the opening of the first cavity 411 of the first housing 1. Correspondingly, an assembly convex ring 21 is provided at the opening of the second cavity 412 of the second housing 2, so that the assembly convex ring 21 and the inner ring groove 11 are inserted and matched to realize the positioning connection between the first housing 1 and the second housing 2. And glue is applied between the two, so that the bonding area is larger, improving the connection strength, and the glue applied on the ring surface can achieve complete circumferential sealing.

[0056] Among them, a ring - shaped first assembly part 33 is provided on the outer periphery of the third housing 3 in this embodiment. Correspondingly, a ring - shaped and stepped second assembly part 13 is provided on the inner peripheral wall of the first housing 1, so that a part of the third housing 3 facing the third chamber is inserted into the inner periphery of the second assembly part 13, and is positioned by the abutment of the first assembly part 33 and the second assembly part 13. And glue is applied and fixed and sealed between the outer periphery of the part of the third housing 3 inserted into the inner periphery of the second assembly part 13 and the inner periphery of the second assembly part 13, and glue is applied and fixed and sealed between the first assembly part 33 and the second assembly part 13, so that the bonding area is larger, improving the connection strength, and the glue applied on the ring surface can achieve complete circumferential sealing.
