AI Technical Summary
In existing technologies, the vibration damping structure of the microphone head cannot effectively prevent sound wave impact, resulting in frequent popping and feedback phenomena, which affect the sound reception quality.
The microphone pickup head assembly is designed with a support pillar and a shield on the top surface of the bracket. There is a gap between the baffle of the shield and the top surface of the pickup head, so that the sound waves can bypass the baffle and enter from the side, avoiding direct impact on the top surface of the pickup head.
It effectively prevents popping and feedback, thus improving the quality of radio reception.

[0032] The technical scheme of the embodiments of the utility model will be described clearly and completely in combination with the drawings of the embodiments of the utility model. Obviously, the following described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.
[0033] In order to make the technical scheme and implementation mode of the utility model clearer and more clearly, the following introduces several preferred specific embodiments for realizing the technical scheme of the utility model.
[0034] It should be noted that the direction words such as "inner, outer", "front, back" and "left, right" in this paper are described based on the product use state as the reference object. Obviously, the use of the corresponding direction words does not constitute a limitation on the protection scope of the scheme.
[0035] As shown in Figure 1 , Figure 2 The utility model provides a kind of anti-spray anti-whistling microphone, including shell 10 and the pickup head assembly 20 being set in shell 10.
[0036] As shown in Figure 3 , Figure 4 The pickup head assembly 20 includes support 21, sound head seat 22, pickup head 23 and shielding cover 24.
[0037] Two support columns 211 are provided on the top surface of the support 21. In this embodiment, the support columns 211 are cylindrical, and the axes of the two support columns 211 are coplanar with the axis of the support 21. Insertion shafts 212 are provided at the upper ends of the two support columns 211, and the diameter of the insertion shafts 212 is smaller than the diameter of the support columns 211. Obviously, to further improve stability, more than two support columns 211 can also be provided.
[0038] like Figure 5 , Figure 6 As shown, the microphone head 22 includes a base 221, which has an open-top cavity 222, and the microphone head 23 is disposed in the cavity 222. The outer side of the base 221 is provided with a mounting sleeve 223 that matches the support column 211, and the insertion shaft 212 is inserted into the mounting sleeve 223.
[0039] like Figure 7 As shown, the shielding cover 24 includes a baffle 241, on which a sleeve 242 that matches the mounting sleeve 223 is provided, and the sleeve 242 is fitted onto the mounting sleeve 223. With this structure, the shielding cover 24 is easy to assemble.
[0040] In this embodiment, the two sleeves 242 are provided with strip grooves 243 on their opposite sides, making installation more convenient.
[0041] In addition, the depth of the shaft hole of the sleeve 242 is less than the length of the sleeve 242. As a result, after the shield 24 is installed on the microphone head seat 22, there is a gap between the baffle 241 and the top surface of the pickup head 23. The sound waves entering from the pickup hole of the housing 10 are blocked by the baffle 241, bypass the baffle 241 and enter from the side into the gap between the baffle 241 and the top surface of the pickup head 23, and are picked up by the pickup head.
[0042] This design structure ensures that sound waves do not directly impact the top surface of the microphone 23, but instead bypass the baffle 241 and enter from the side, thus effectively preventing popping and feedback.
[0043] Based on the above description of specific embodiments, the anti-puff and anti-feedback microphone provided by this utility model has the following advantages compared with the prior art:
[0044] First, the upper part of the microphone assembly bracket is equipped with a shield. There is a gap between the shield baffle and the top surface of the microphone. The sound waves entering from the microphone hole of the outer shell will not directly impact the top surface of the microphone, but will bypass the baffle and enter from the side, which can effectively prevent popping and feedback.
[0045] Secondly, the shielding cover has two sleeves on its baffle plate. The sleeves are fitted onto the microphone head, which is simple in structure and easy to assemble.
[0046] Finally, it should be noted that the terms "comprises", "comprising", or any other variation thereof, used in the present document are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but can also include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without limitation, an element preceded by "comprises a... " does not, without more constraints, foreclose the existence of additional identical elements in the process, method, article, or apparatus that comprises the recited element.
[0047] The utility model is not limited to the above best embodiment, any person should know the structural change made under the enlightenment of the utility model, any technical scheme with the same or similar to the utility model falls into the protection scope of the utility model.
