Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a wind screen that can be detachably placed over the tip of a microphone.

[Prior Art] As is well known, this type of windscreen is made of a Scotto filter, breathable urethane foam, etc., and is placed over a microphone for the purpose of preventing the generation of wind noise. However, when used for close-range vocals, etc., distortion may occur due to pop sounds or high sound pressure. Furthermore, when used outdoors, the current situation is that wind noise cannot be sufficiently prevented if the wind is strong. Therefore, in the past, the windscreen was further covered with stockings, cloth, etc. to prevent the generation of noise, but this had drawbacks such as poor visibility and time-consuming installation.

[Purpose of the invention] This invention improves the drawbacks of the conventional windscreen as described above, and provides a microphone windscreen that can effectively prevent distortion even when used for close vocals, etc. It is something.

[Structure of the invention] An embodiment of this invention shown in the drawings will be described below.

This windscreen 1 is made of, for example, breathable urethane foam, and has an opening 3 at one end into which a microphone 2 is inserted. The other end 4 of this windscreen 1 and the opening 3
A notch 7 formed in a donut shape is provided between the bottom 5 and the center 6. This notch 7 extends in a direction substantially perpendicular to the axis of the windscreen 1 and forms an air layer 8. As a result, there are a first urethane layer 9, an air layer 8, and a second urethane layer 1 between the tip of the microphone 2 and the other end 4 of the windscreen 1.
0 will be formed.

[Effect of the invention] As described above, in this windscreen 1, a damper is formed by the air layer 8 between the tip of the microphone 2 and the sound source located on the other end 4 side of the windscreen 1, so that noise is reduced. In particular, pop noise when used as a close-range vocal can be reduced by 6 to 10 dB compared to conventional windscreens.
Moreover, this air layer 8 is
It can be constructed by simply cutting out the outer circumferential surface of the windscreen 1 between the other end 4, which is the tip of the microphone 2, and the bottom 5 of the opening 3 into which the tip of the microphone 2 is inserted, leaving a central portion 6, making it a completely separate member. Since it does not require , it can be provided at low cost.

In the above-described embodiment, the air layer 8 is one layer, but by providing a plurality of layers, noise can be further reduced.

[Brief explanation of drawings]

The drawing is a longitudinal sectional view showing an embodiment of this invention. In the figure, 1 is a windscreen, 2 is a microphone, 3 is an opening, 7 is a notch, and 8 is an air layer.

Claims (1)

[Scope of utility model registration request] In a wind screen made of open cell material such as urethane foam, which has an opening for inserting a microphone at the rear end, and which is placed over the tip of the microphone from this opening, the windscreen at the tip and the portion that comes into contact with the tip of the microphone. 1. A windscreen for a microphone, characterized in that the windscreen has a notch formed in a substantially donut shape leaving a central portion in order to form at least one layer of air.
