Abstract

The utility model discloses a microphone wind-proof cover. The wind-proof cover comprises a cover body and a cover body bracket. The cover body is arranged outside of the cover bracket, and a bonding ring is arranged at the opening position below the bracket and the cover body. The microphone wind-proof cover has the best wind-proof effects, and meanwhile the influence on the voice is minimized. Due to the fact that the design of framework is added, the service life of the wind-proof cover is greatly prolonged.

Description

A kind of microphone hurricane globe

Technical field

The utility model relates to the microphone annex, relates in particular to a kind of microphone hurricane globe.

Background technology

Hurricane globe, as an accessory product of microphone, its Main Function is windproof, and is dustproof, anti-ly is similar to cough, the low-frequency noise such as sneeze.Directly be enclosed within on the pick-up head of microphone during use.

At present, along with more and more higher to the microphone quality of people, also have higher requirement as the hurricane globe to its annex.Major embodiment is 2 points below:

Hurricane globe had better not exert an influence to the pickup effect of original microphone under windproof, the dustproof effect guaranteeing.

Hurricane globe in use should be accomplished not fragile.

Hurricane globe generally adopts high-density sponge to make, because in the sound spectrum, frequency is lower, wavelength is longer; Frequency is higher, and wavelength is shorter.If hurricane globe wants to play windproof effect, can by increasing wall thickness, high frequency response may will be reduced but increase wall thickness, so that high-frequency sensitivity reduces generally speaking.Referring to Fig. 2.It is a diameter 20mm condenser microphone hurricane globe profile.

Because the hurricane globe material is high-density sponge, in Reusability, be vulnerable to wearing and tearing, if excessive being easy to of exerting oneself torn, cause at last damaging.Increased the later stage use cost.

Summary of the invention

For solving the problem and blemish of above-mentioned middle existence, the utility model provides a kind of endoporus cut-out at hurricane globe to increase a skeleton that is used for supporting hurricane globe.Described technical scheme is as follows:

A kind of microphone hurricane globe comprises:

Cover body, hood pedestal, described cover body is arranged on the outside of described hood pedestal, and is provided with the gummed circle at support and cover body lower opening place.

The beneficial effect of the technical scheme that the utility model provides is:

1) the utility model is accomplished the impact of sound is minimized when playing best protection effect.

2) increase frame design, greatly prolonged the useful life of hurricane globe.

Fig. 2 is microphone balance housing schematic diagram;

Fig. 3 is hurricane globe body structure schematic diagram;

Fig. 4 a and 4b are the embedded skeleton front view of hurricane globe and vertical view;

Fig. 5 is that hurricane globe uses the structural representation on microphone.

Embodiment

For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing the utility model execution mode is described in further detail:

As shown in Figure 2, showed the structure of microphone hurricane globe, having comprised: cover body 1, hood pedestal 2, described cover body is arranged on the outside of described hood pedestal, and is provided with gummed circle 3 at support and cover body lower opening place.

Be hollow form between above-mentioned hood pedestal and the cover body.

The outer setting of above-mentioned cover body has spongy layer.

The outer surface of above-mentioned spongy layer has been installed with fine hair 4.

Fig. 4 a and 4b are the embedded skeleton structures of hurricane globe, skeleton adopts Mold Making, consideration intensity and pliability are selected the polytetrafluoro material, its wall is the muscle support by four 2mm, an annulus is done on the top, when being inserted in hurricane globe, the top is stuck in the top of microphone, thereby fixedly hurricane globe is in the position of microphone.Because being enclosed within the position of microphone no longer is the hurricane globe bulk material, and employing polytetrafluoro material, so greatly improved the useful life of hurricane globe, for conveniently being inserted in the microphone, skeleton is transferred opening part and is adopted four slopes excessive, in the very light Probe microphone, also conveniently take off simultaneously in the use.The hurricane globe body that increases the skeleton support is not yielding.Hurricane globe body and support frame are transferred opening part at it and are adopted gummed to process, and do not affect the visual effect of hurricane globe integral body.

This external surface of hurricane globe adopts flocking to process, and so-called flocking is enclosed one deck fine hair at this external surface of hurricane globe, its effect exactly: the 1st, and the protection effect of enhancing hurricane globe, the 2nd, the intensity of increase hurricane globe makes it not fragile.The 3rd, the texture of increase hurricane globe is improved the grade.

For solving the hurricane globe use to the impact of frequency response, present embodiment proposes the hurricane globe endoporus is done its not direct contact microphone pick-up head outer wall of ambassador, thereby form an ante-chamber (as shown in Figure 3), reduce the wall thickness of hurricane globe, thereby reduce the impact on former high frequency curve, hurricane globe is enclosed within (referring to Fig. 5) when using on the microphone, sound of the wind is beaten when the hurricane globe outer wall, because the hurricane globe inwall designs for arc and with the microphone pick-up head one segment distance is arranged, so that the sound wave of sound of the wind can flow along with the inwall of hurricane globe and be shunted, reduce entering the part of microphone pick-up head, thereby reach windproof purpose.

Use the utility model hurricane globe windproof in the actual Test Application, there is good performance dustproof aspect, and can not cause too many impact to the microphore response before using.

The above is preferred embodiment of the present utility model only, is not limited to the utility model, and is all within spirit of the present utility model and principle, any modification of doing, is equal to replacement, improvement etc., all should be included within the protection range of the present utility model.
