[0039] Please refer to Figure 3-Figure 4 ,as well as Figure 7 , Figure 7 for Figure 2 In this embodiment, the waterproof breathable membrane module 500 further includes a ring-shaped waterproof breathable membrane upper film 504, which is arranged at the edge of one side of the waterproof breathable membrane 503, and the waterproof breathable membrane upper film 504 is fixedly sealed to the rear shell speaker slot 603, and the waterproof breathable membrane 503, the waterproof breathable membrane upper film 504, and the rear shell speaker slot 603 are surrounded to form the first cavity 503a.

[0040] In addition to the waterproof breathable membrane 503, the waterproof breathable membrane module 500 may also include a waterproof breathable membrane upper film 504, which is annular in shape and arranged at the edge of one side of the waterproof breathable membrane 503. The waterproof breathable membrane upper film 504 can be fixedly sealed on the rear shell speaker slot 603. Due to the existence of the waterproof breathable membrane upper film 504, the waterproof breathable membrane 503 is not directly arranged on the rear shell, but the waterproof breathable membrane upper film 504 is used to separate the waterproof breathable membrane 503 from the rear shell speaker slot 603, and the waterproof breathable membrane 503, the waterproof breathable membrane upper film 504, and the rear shell speaker slot 603 are surrounded to form the first cavity 503a mentioned above, which forms a waterproof sealed closed loop with the waterproof breathable membrane 503. The sound waves of the speaker 410 first enter the first cavity 503a through the waterproof breathable membrane 503, and then pass through the rear shell speaker slot 603.

[0041] In the related art, since the waterproof breathable membrane 503 is directly attached to the shell, it will not only cause audio attenuation, thereby affecting the sound volume of the entire speaker 410. At the same time, when the speaker 410 is working, the waterproof breathable membrane 503 will resonate, and contact with the shell will cause noise, thereby affecting the overall performance of the speaker 410. In this embodiment, a waterproof breathable membrane upper film 504 is added, so that the waterproof breathable membrane upper film 504 clamps one side of the waterproof breathable membrane 503, which can improve the waterproof breathable membrane 503 resonance fluctuation noise and other problems.

[0042] Optionally, the waterproof breathable membrane upper film 504 may be a PC sheet on the waterproof breathable membrane 503 .

[0043] In this embodiment, the waterproof breathable membrane module 500 also includes a first adhesive component 505 arranged on the side of the waterproof breathable membrane upper film 504 away from the waterproof breathable membrane 503, the first adhesive component 505 is bonded to the rear shell speaker slot 603, and the waterproof breathable membrane 503, the waterproof breathable membrane upper film 504, the first adhesive component 505, and the rear shell speaker slot 603 are surrounded to form the first cavity 503a.

[0044] In addition to the above components, the waterproof breathable membrane module 500 may also include a first adhesive member 505, which is disposed on the side of the waterproof breathable membrane upper film 504 away from the waterproof breathable membrane 503, so the first adhesive member 505 is also annular. One side of the first adhesive member 505 can be bonded to the waterproof breathable membrane upper film 504, and the other side can be bonded to the rear shell speaker slot 603, so that the waterproof breathable membrane upper film 504 is bonded to the rear shell speaker slot 603. At the same time, the waterproof breathable membrane 503, the waterproof breathable membrane upper film 504, the first adhesive member 505, and the rear shell speaker slot 603 are jointly surrounded to form the above-mentioned first cavity 503a.

[0045] Optionally, the first adhesive member 505 may be foam glue, that is, foam glue on the waterproof breathable film 504. Therefore, this embodiment can also be understood as the waterproof breathable film 503 being located above the groove of the rear shell speaker 410 and fixed by foam glue.

[0046] In this embodiment, the rear shell speaker slot 603 is provided with a groove, and the vehicle-mounted device 1 further includes a rear shell dustproof net 602, and the rear shell dustproof net 602 is fixed in the groove.

[0047] In addition to the above-mentioned components, the vehicle-mounted device 1 may also include a rear shell dustproof net 602. In this embodiment, a groove can be opened on the rear shell speaker slot 603, so that the rear shell dustproof net 602 can be fixed in the groove of the rear shell speaker slot 603 by glue or self-adhesive to prevent external particles from entering the first cavity 503a, that is, the front sound cavity of the speaker 410.

[0048] In this embodiment, the distance between the rear shell dustproof net 602 and the waterproof breathable membrane 503 is 0.5mm-2mm. The rear shell dustproof net 602 is arranged on the basis of the groove in the rear shell speaker slot 603, and the first adhesive member 505 can be bonded to the rear shell dustproof net 602. Due to the existence of the first adhesive member 505 and the film 504 on the waterproof breathable membrane, there is a certain distance between the waterproof breathable membrane 503 and the rear shell dustproof net 602, that is, the waterproof breathable membrane 503 is separated from the rear shell dustproof net 602, which can further increase the sound output area of ​​the waterproof breathable membrane 503, reduce the sound attenuation, and increase the sound output volume of the strong speaker 410. Specifically, the distance can be 0.5mm-2mm, and this embodiment is only schematically described with a distance of 1mm.

[0049] In this embodiment, the waterproof breathable membrane module 500 also includes a ring-shaped waterproof breathable membrane lower film 502, which is arranged at the edge of the other side of the waterproof breathable membrane 503, and the waterproof breathable membrane lower film 502 is fixedly sealed to the speaker 410, and the waterproof breathable membrane 503, the waterproof breathable membrane lower film 502, and the speaker 410 are surrounded to form the second cavity 503b.

[0050] In addition to the waterproof breathable membrane 503, the waterproof breathable membrane module 500 may also include a film 502 under the waterproof breathable membrane. The film 502 under the waterproof breathable membrane is annular in shape and is arranged at the edge of the other side of the waterproof breathable membrane 503. In other words, the waterproof breathable membrane 503 is composed of an upper and lower film sandwich design. The film 502 under the waterproof breathable membrane can be fixedly sealed on the speaker 410. Due to the existence of the film 502 under the waterproof breathable membrane, the waterproof breathable membrane 503 is not directly arranged on the speaker 410, but the film 502 under the waterproof breathable membrane is used to separate the waterproof breathable membrane 503 from the speaker 410, and the waterproof breathable membrane 503, the film 502 under the waterproof breathable membrane, and the speaker 410 are surrounded to form the second cavity 503b mentioned above, forming the front sound cavity structure of the speaker 410. The sound waves of the speaker 410 first pass through the second cavity 503b to reach the waterproof breathable membrane 503, then enter the first cavity 503a, and finally pass through the dustproof net 602 of the rear shell, which can adjust the high-frequency sound quality of the speaker 410. In this embodiment, a film 502 under the waterproof breathable membrane is added, so that the film 502 under the waterproof breathable membrane clamps the other side of the waterproof breathable membrane 503, which can further improve the resonance and fluctuation noise of the waterproof breathable membrane 503 and other problems.

[0051] Optionally, the film 502 under the waterproof breathable membrane can be a PC sheet under the waterproof breathable membrane 503 .

[0052] Please refer to Figure 4-Figure 5In this embodiment, a ring-shaped speaker edge bone 411 is convexly provided on the peripheral side of the speaker 410, and the waterproof breathable membrane lower film 502 is fixedly sealed to the speaker edge bone 411. A circle of protrusions may be convexly provided on the outer periphery of the speaker 410, and the protrusions are the speaker edge bone 411. The speaker 410 is located above the waterproof breathable membrane 503. By fixing and bonding the waterproof breathable membrane lower film 502 on the speaker edge bone 411, the speaker 410 can be prevented from vibrating, and the sound stability of the speaker 410 in the working state can be ensured.

[0053] In this embodiment, the waterproof breathable membrane module 500 also includes a second adhesive member 501 provided on the side of the waterproof breathable membrane lower film 502 away from the waterproof breathable membrane 503, the second adhesive member 501 is bonded to the speaker 410, and the waterproof breathable membrane 503, the waterproof breathable membrane lower film 502, the second adhesive member 501, and the speaker 410 are arranged to form the second cavity 503b.

[0054] In addition to the above components, the waterproof breathable membrane module 500 may also include a second adhesive member 501, which is disposed on the side of the waterproof breathable membrane lower film 502 away from the waterproof breathable membrane 503, so the second adhesive member 501 is also annular. One side of the second adhesive member 501 may be bonded to the waterproof breathable membrane lower film 502, and the other side may be bonded to the speaker 410, thereby bonding the waterproof breathable membrane lower film 502 to the speaker 410. At the same time, the waterproof breathable membrane 503, the waterproof breathable membrane lower film 502, the second adhesive member 501, and the speaker 410 may be surrounded to form the second cavity 503b mentioned above.

[0055] Optionally, the second adhesive member 501 may be foam glue, that is, foam glue of the waterproof breathable membrane lower film 502. Therefore, this embodiment can also be understood as the speaker 410 being located above the waterproof breathable membrane 503 and fixed by the foam glue.

[0056] Therefore, the waterproof breathable membrane module 500 is composed of a waterproof breathable membrane lower film 502 and a waterproof breathable membrane upper film 504, which are bonded by glue. The waterproof breathable membrane lower film 502 and the waterproof breathable membrane upper film 504 are respectively attached with a second adhesive component 501 and a first adhesive component 505. The first adhesive component 505, the waterproof breathable membrane upper film 504, the waterproof breathable membrane 503, the waterproof breathable membrane lower film 502, and the second adhesive component 501 together constitute the waterproof breathable membrane module 500.
