[0020] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict.

[0021] like Figures 1 to 6In the embodiment of the microphone fixing structure of the utility model shown, the microphone fixing structure includes a soft shell 1, a waterproof sound-permeable membrane 2, a hard shell 3 and a mounting plate 4, and one end surface of the soft shell 1 and the hard shell 3 is provided with a sound hole 101; the soft shell 1 includes an outer shell 11 and an inner shell 12, the microphone is fixedly arranged in the inner shell 12, the inner shell 12 is fixedly arranged in the outer shell 11, and the outer shell 11 is fixedly arranged in the hard shell 3; because the soft shell 1 is made of soft material, the microphone is interference fit with the inner shell 12, the inner shell 12 and the outer shell 11, and the outer shell 11 and the hard shell 3; in this way, the microphone can be fixed more firmly, and the microphone is fixed by the double-layer soft shell 1, so that the noise on the hard shell 3 is not easily transmitted to the microphone.

[0022] Fixing of the hard shell 3: The end face of the hard shell 3 away from the sound hole 101 is fixedly mounted on the mounting plate 4. Specifically, the hard shell 3 is fixedly connected to the mounting plate 4 through a connecting ear 31 fixedly arranged on the side wall. The mounting plate 4 fixes the outer shell 11 in the hard shell 3, and the mounting plate 4 also fixes the microphone head in the inner shell 12. In this way, the microphone head can be fixed more firmly.

[0023] Fixing of the outer shell 11 in the hard shell 3: A convex ring 111 is provided on the side wall of the outer shell 11 opposite to the end where the sound hole 101 is provided, and the thickness of the convex ring 111 is consistent with the thickness of the outer shell 11, and the diameter of the convex ring 111 at the end away from the sound hole 101 is larger than that at the other opposite end, so the convex ring 111 is inclined as a whole; the convex ring 111 can be embedded in the corresponding groove on the hard shell 3, so the outer shell 11 can be fixed in the hard shell 3; in this way, the outer shell 11 is fixed in the hard shell 3 more stably.

[0024] Fixing of the waterproof sound-permeable membrane 2: A waterproof ring 21 is clamped and fixed at the convex ring 111 between the side walls of the outer shell 11 and the inner shell 12. Specifically, the waterproof ring 21 is fixedly arranged in the installation cavity 1101 formed between the convex ring 111 and the outer shell 11. The installation cavity 1101 is also inclined. Since the diameter of the end of the convex ring 111 away from the sound hole 101 is larger than the other end opposite to it, the outer shell 11 and the inner shell 12 can firmly clamp and fix the waterproof ring 21 at the installation cavity 1101 to prevent the waterproof ring 21 from being in the installation cavity 1101. Produce axial displacement; the end of the waterproof ring 21 facing the sound hole 101 is provided with a clamping groove for clamping and fixing the waterproof sound-permeable membrane 2, and the waterproof sound-permeable membrane 2 can be fixed in the clamping groove of the waterproof ring 21 by glue or other means; in this way, the waterproof sound-permeable membrane 2 is more firmly fixed in the clamping groove, and at the same time, the waterproof ring 21 is also more firmly fixed in the installation cavity 1101; the waterproof sound-permeable membrane 2 is fixedly installed between the outer shell 11 and the inner shell 12, which can also prevent the microphone from vibrating during the working process and causing wear of the waterproof sound-permeable membrane 2.

[0025] In one embodiment of the present application, preferably, Figure 5As shown, a protective pad 121 is fixedly provided at one end of the inner shell 12 close to the sound hole 101, and the protective pad 121 and the end face of the outer shell 12 clamp the waterproof sound-permeable membrane 2 together to prevent the microphone from directly contacting the waterproof sound-permeable membrane 2 and causing damage to the waterproof sound-permeable membrane 2; a fixing pad 122 is fixedly provided at one end of the inner shell 12 away from the sound hole 101, and the fixing pad 122 is used for when the hard shell 3 is fixedly mounted on the mounting plate 4, the mounting plate 4 directly contacts the fixing pad 122 instead of the microphone, so that the noise on the mounting plate 4 is not easily transmitted to the microphone; when the hard shell 3 is fixedly mounted on the mounting plate 4, the fixing pad 122 and the microphone have an interference fit, which can make the fixation of the microphone more stable; in addition, a wiring harness hole 102 is provided on the fixing pad 122, and a wiring point or wiring harness hole is correspondingly provided on the mounting plate 4.

[0026] In one embodiment of the present application, preferably, Figure 5 , Figure 6 As shown, the soft shell 1 is made of a soft elastic material in one piece, such as a thermoplastic elastomer (TPE) material, which can be easily processed and formed; specifically, the place where the outer shell 11 and the inner shell 12 are fixedly connected is at the end face of the soft shell 1 away from the sound hole 101; the protective pad 121 and the fixed pad 122 are provided in plurality to facilitate the installation of the waterproof ring 21 and the waterproof sound-permeable membrane 2; the plurality of fan-shaped protective pads 121 are directly fixedly connected to the inner wall of the inner shell 12; the plurality of fan-shaped fixed pads 122 are fixedly connected to the inner wall of the inner shell 12 through the connecting arm 1211, so that when the inner shell 12 is flipped into the outer shell 11 after the one-piece processing, the fixed pad 122 is also flipped into the outer shell 11.

[0027] In one embodiment of the present application, preferably, Figure 4 , Figure 5 As shown, one end of the convex ring 111 close to the sound hole 101 coincides with the end face of the housing 11, so that the bent portion of the waterproof sound-permeable membrane 2 is always at the exit of the clamping groove of the waterproof ring 21. In this way, the waterproof ring 21 can be installed more conveniently and the waterproof sound-permeable membrane 2 can be prevented from being damaged due to multiple bending during the installation process.

[0028] In one embodiment of the present application, preferably, Figure 5 As shown, the waterproof ring 21 is columnar and made of soft elastic material. Thus, when the waterproof ring 21 is clamped between the outer shell 11 and the inner shell 12, the waterproof ring 21 is deformed at the clamping groove due to the inclined installation cavity 1101. After the deformation, a force is generated to clamp the waterproof sound-permeable membrane 2, making the waterproof sound-permeable membrane 2 more firmly fixed.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
