The microphone watertight fittings of a brand-new design is as shown in fig. 1 and fig. 2 jointly to the problem that the microphone laterally installed on the side wall of the inclined shell in the existing wearable device is difficult to keep applying constant pressure on the waterproof breathable film 11 for a long time, the waterproof and breathable effects of the waterproof breathable film 11 cannot be guaranteed, and the intelligent degree of the assembly process is low. Specifically, a microphone sound hole 12 is opened in the case 10 of the wearable device. A waterproof breathable membrane 11 is provided inside the sound hole 12 for dual requirements of waterproofing and sound pickup. The material of the waterproof breathable film 11 can be the breathable film material and the product which are common in the prior art, and the brand and the manufacturer are not limited. The fixing means between the waterproof breathable film 11 and the casing 10 can be adhesive fixing or other mounting means. The microphone body 13 is disposed inside the waterproof breathable film 11. In order to keep a constant pressure on the waterproof breathable membrane 11 for a long time, making it even and wrinkle-free, a support plate 14 and a microphone attachment 30 are also provided in the microphone waterproofing device. The support plate 14 is disposed inside the microphone body 13, and the microphone connecting portion 30 is fixedly connected to the support plate 14 and the housing 10 of the wearable device, respectively. When the assembly is completed, the supporting plate 14 and the microphone body 13 are arranged in the same direction, i.e., inclined in the same direction, under the supporting action of the microphone connecting part 30. On one hand, due to the supporting function of the microphone connecting part 30, the supporting plate 14 applies a certain pressure towards the direction of the waterproof breathable film 11, and the supporting plate 14 with a flat and uniform surface can ensure that the external force acting on the waterproof breathable film 11 is uniform and stable; on the other hand, the microphone connecting part 30 can be directly connected with the inclined casing 10, and the whole connecting structure is stable and reliable.

As shown in fig. 7, an alternative connection mode is that a screw hole 18 is formed on the side wall of the housing 10, and a bolt 19 sequentially extends into the through screw hole 17 and the screw hole 18 to complete connection. The vertical mounting of the bolts 19 can be done by a robot or other automated equipment, greatly improving production efficiency.
In a common wearable device housing 10 design as shown in fig. 8, such as a smart watch, a smart wristband, etc., a sidewall is usually designed to be inclined inward from top to bottom, i.e., the upper end face of the housing 10 is large, so as to design a display screen or touch keys, etc. In this design, as shown in fig. 1 to 7, the microphone body 13 is preferably disposed to be inclined inward, and correspondingly, the supporting plate 14 is also disposed to be inclined inward, the included angle α between the first side wall 15 and the second side wall 16 is greater than 90 degrees, and the through screw hole 17 is disposed to be inclined from inside to outside from top to bottom, so as to satisfy both the waterproof and breathable requirements of the waterproof breathable film and the loading and unloading requirements for facilitating mechanized installation.
As shown in fig. 2 and 5, the waterproof breathable film 11 needs to be flat and wrinkle-free in the use state so as to achieve good acoustic effect. In order to further ensure the flatness of the waterproof breathable membrane 11, a support steel sheet 23 is preferably provided in the microphone waterproofing device.

Preferably, the waterproof breathable film 11 is fixedly arranged on the mounting plate 32, for example, as shown in fig. 5, the waterproof breathable film 11 can be inserted into a through hole on the mounting plate 32; alternatively, the waterproof, breathable membrane 11 may be integrally attached to the mounting plate 32 and partially exposed from the through-holes in the mounting plate 32. The mounting plate 32 is fixedly connected with the shell 10, and the supporting steel sheet 23 is fixedly connected with the mounting plate 32. The area of the supporting steel sheet 23 is preferably larger than that of the mounting plate 32 to provide a good supporting function of the waterproof and breathable membrane.
As shown in fig. 2, in terms of sound channel design, a first sound cavity 27 is formed in the microphone body 13, a sound pickup hole 26 is opened on a side of the microphone body 13 facing the waterproof breathable film 11, and the sound pickup hole 26 is communicated with the first sound cavity 27. Thus, the shortest distance is provided between the microphone body 13 and the waterproof breathable film 11, and the sound pickup hole 26 is closest to the sound source, so that the microphone has the best acoustic characteristics. The microphone body 13 and the main chip, that is, the PCB 29 are preferably connected through a flexible circuit board 28, the flexible circuit board 28 is preferably disposed inside the supporting steel sheet 23, the flexible circuit board 28 and the supporting steel sheet 23 are fixed by adhering the double-sided tape 22, and the flexible circuit board 28 is provided with a through hole corresponding to the sound pickup hole 26.
On one side of the waterproof breathable film 11, a first through hole 25 is formed on the supporting steel sheet 23, and a second through hole 24 is formed on the double-sided adhesive tape 22. The waterproof breathable film 11, the first through hole 25 and the second through hole 24 enclose a second sound cavity 27, and due to the design of the supporting steel sheet 23, the waterproof breathable film 11 can be kept flat in the whole assembling process, the pressure applied on the waterproof breathable film is stable and reliable, and the pickup effect of the second sound cavity 27 can be reliably guaranteed.
