[0003] Using physical methods to reduce noise is a method that people often use to reduce vibration and noise. For example, most microphones have sponges or other flexible and resilient pads at the bottom of the microphone head. This can reduce the vibration and noise generated between the microphone head and the fixed bracket. However, this structure can only eliminate noise in some channels. For some devices with strict noise control, the noise reduction effect needs to be further improved. Utility Model Content

[0034] The base 131 has a microphone cavity 134 formed inside, a microphone 15 is arranged inside the microphone cavity 134, the microphone cavity 134 is a T-shaped structure as a whole, a microphone hole 135 is formed inside the microphone cavity 134 and passes through the top of the microphone cavity 134, and the bracket body 13 is made of a plastic or silicone material with certain flexibility and resilience, so that the microphone cavity 134 inside the base 131 forms a space with certain telescopic resilience;
[0035] In this way, the microphone hole 135 is opened at the top of the microphone cavity 134, and the bottom of the microphone cavity 134 is designed as an opening, and its opening diameter is smaller than the diameter of the microphone cavity 134. The microphone 15 passes through the opening and is inserted into the microphone cavity 134. The microphone 15 can be directly inserted into the microphone cavity 134 without glue, which has higher stability and is simpler and more convenient to assemble.
[0036] In some embodiments, as shown in the attached Figure 1 As shown, the sealed rear shell 12 has a groove of a certain depth inside, and a limiting platform 121 is arranged above the groove. The bracket body 13 is installed in the groove, and the frame body 133 on the bracket body 13 contacts the limiting platform 121 to form a limiting state of the bracket body 13;
[0037] In this way, the depth of the groove is greater than the thickness of the bracket body 13, so as to increase the avoidance space of the bracket body 13, so that the base 131 and the arched damper 132 on the bracket body 13 are both in a suspended state, preventing the base 131 and the arched damper 132 from contacting the bottom of the groove, so as to isolate the vibration generated by the external shell from being directly transmitted to the base 131 and affecting the noise reduction effect of the microphone 15.
[0038] like Figure 1 and Figure 4-Figure 7 As shown, a mounting groove 111 is provided on one side of the sealed front shell 11, a PCB board 16 is provided in the mounting groove 111, and the PCB board 16 is electrically connected to the microphone 15. The microphone bracket body 1 also includes a mesh cover 14, which is fixed on the top of the sealed front shell 11. The sealed front shell 11 is a hollow structure with upper and lower ends interpenetrating each other. The opening at the upper end of the sealed front shell 11 is smaller than the opening at the lower end. The sealed rear shell 12 passes through the opening at the lower end of the sealed front shell 11 and is sleeved in the internal cavity of the sealed front shell 11. A plurality of holes are provided on the mesh cover 14, which are connected to the opening at the upper end of the sealed front shell 11, wherein the microphone hole 135 provided on the bracket body 13 corresponds to the opening at the upper end of the sealed front shell 11, and the microphone hole 135 is located in or below the opening at the upper end of the sealed front shell 11, and the two are connected.

The thickness of the arched elastic wave 132 is less than the thickness of the base 131 and the frame body 133. When the device shell itself vibrates, the arched elastic wave 132 will be deformed by force, thereby further improving the elasticity of the base 131 to achieve energy absorption and shock reduction effects. At the same time, the resilience of the microphone 15 on the base 131 is also improved, and the vibration between the base 131 and the frame body 133 is reduced, so that the microphone 15 has a better noise reduction effect;
[0041] The support body 13 of the utility model is provided with a microphone cavity 134 adapted to the matched microphone 15, and the microphone 15 is installed in the microphone cavity 134. The support body 13 is made of plastic or silicone material with certain flexibility and resilience as a whole, so that the microphone 15 installed in the base 131 and the external hard shell form a soft connection state, further reducing vibration and improving the noise reduction effect of the microphone 15. The microphone cavity 134 is a T-shaped structure as a whole, and has certain telescopic resilience performance. After the microphone 15 is inserted into the microphone cavity 134, the inner wall of the microphone cavity 134 shrinks and tightly wraps the microphone to prevent the microphone from shaking or vibrating, so that the microphone cavity 134 has a certain telescopic resilience space, and the microphone 15 can be directly inserted into the microphone cavity 134 without glue, so that the stability is higher, and the assembly is simpler and more convenient;
[0042] The utility model provides a sealed front shell 11 and a sealed rear shell 12, so that the microphone 15 installed inside is in a relatively closed space environment, and the collected sound can only reach the microphone 15 through the holes of the mesh cover 14, which has a certain effect of reducing noise.
