DETAILED DESCRIPTION OF THE INVENTION The water groove @ relates to a windscreen
suitable for use in superdirective microphones used outdoors. As is well known, when shooting a
movie outdoors and simultaneously recording audio, the sound of the wind flowing through the
microphone becomes a loud noise that exceeds the beka level of the audio to be recorded. (1), 45-CF33v may be carried out. In order to prevent the wind from directly hitting the microphone T,
a t-shaped windscreen formed of a porous metal plate is attached so as to cover the head of the
microphone. However, when the whole surface of the microphone or the neck of the ftctrl
microphone is supported and contacts or collides with the outside of the mi-mirror screen, the
direct sound of the windscreen and the indirect sound such as the resonance sound or rattling
noise are directly Intruding into the microphone, causing a large level of noise reproduction,
which is not preferable. Although a vibration isolation member such as unnotan resin is
interposed between the windscreen and the microphone, the vibration isolation member also has
a sound absorbing effect, so that the loudness level characteristics and high frequency range of
the voice are high. Low F on the level can not be avoided. Such a phenomenon is noticeable (or is
not desirable when the long cylindrical snail formed superdirective microphone is housed in the
wind screen (и, but is not preferable). In addition, when stuffing between the windscreen and the
microphone (1), the passage of the sound entering the windscreen (2) will be blocked, and
various noises such as reflected sound will be generated and recording size In some cases, the
fidelity of reproduction may be lacking. The present invention is intended to prevent the abovementioned adverse effects due to stuffing between the wind screen and the microphone, and

therefore the object of the present invention is to '1. It is configured to cover the whole, and
between the main body and the microphone, the tip of the microphone is approximately centered
in the main body; и ?, the microphone holder which supports the microphone resiliently We
propose a new windscreen with at least one installed, noise due to wind + C and noise due to
vibration, and (preventing degradation of the main frequency characteristics). Hereinafter,
embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is an overall oblique view factor showing an embodiment of a windscreen according to the
present invention, and the main body 1 of the windscreen is (3) a front cylinder 2 containing a
sound collecting portion of the microphone and the base of the microphone A screwed ring 41'il
having a knurled on the peripheral surface of these two cylindrical bodies 2 and 3 consisting of a
rear cylindrical body 3 (which accommodates the entire electric circuit), and integrally coupled to
them As shown in FIGS. 2 and 3 (": the main body 1 is enlarged and cut and shown to be portable
because it is supported together by the grip member 6 attached to the attachment and
detachment) It is a front sectional view and a side sectional view of a thing, and a synthetic resin
plate such as a double cylinder 2 ░ 3 '4 AB 8 resin is punched to provide through holes 2? and
3a, which are further heat-breathed: Formed in a cylindrical shape and Close to the inner surface
of the frame 6, 7 and 8 and 9, with a hole of 250 to 300 holes per inch square, 10.11 dumps
wind noise and In order to prevent rainwater etc. from directly infiltrating.
Further, at the left and right ends of the cylindrical body 2, support rings 14 (4) 15 respectively
provided on the outer and inner peripheral surfaces are attached to screws 12.13 for the joint,
and the screws 13 of the support ring 15 are attached A screw 18 provided on a support ring 17
at the open end V'C of the cap 16 is screwed. The nylon nylon 19 described above is stretched on
the inner surface of the camp 16, and the cap 7 '16' i cylindrical body 2 VC can be attached and
detached. The microphone can be easily and easily housed or removed from the container. On
the other hand, the open end yl of the cylindrical body 3 (but also the support ring 20 is
attached, and the screw ring 4 already described is attached to this support ring 2 o (d rotation
and not easily scraped) The superdirective microphones in the two cylinders 2 and 3 are
snopolized by the inner surface G'C of the screwing ring 4 and the screw connection between the
screw 21 and the screw 12 It will be accommodated. 22, 231-j The support ring 14, 2 o иии is a
good hole provided so that the cable of the superdirective microphone can be externally led out.
In addition, it is also possible to adopt the bayonet coupling method to the above-mentioned both
cylindrical bodies 2 and 3'D coupling (5). On the other hand, in the above-mentioned cylindrical
body 2 (in this case, the middle portion is bent in a U shape and bent at both ends, and the plate
spring 24 for yarn protection having diagonally extended end portions depends on the screw 26
as shown in FIG. The base of the holder 27 is attached to the screw 28 and is attached to the Ushaped lower part 26 of the plate spring 24 and has elasticity 1 and strength and constant
strength 1 h formed of synthetic resin such as S resin It says that it is attached. Then, the rod-like
superdirective microphone 30i is press-fitted through the opening 29 of the holder 27 so that
the holder 27 is tightly fixed within the holder 27; At this time, the length of the holder 27 is
17-04-2019
2
appropriately set so that the tip of the super-directional microphone 30 faces the central portion
of the cap 16. However, if the length is longer than necessary, the sound propagation path will be
disturbed. So you need to minimize it as much as possible. Note that the holder 27 may be
provided on one or both of the rear cylinder 3 and the front cylinder 21 if necessary. ), But the
sound to the tip of the superdirective microphone 3o is collected without concentrated sound
and sound can be collected to record sound information with high directivity and SN ratio, and
the main body 1 Even if i / css or a small amount of impulses are received while transporting the
image, recording of shooting sound is prevented in advance by the buffer action of the superoriented microphone 3 ░ (1 plate splasher 24 above, Therefore, high sensitivity and relatively
rough use and high sensitivity 5 degree sound collection become possible.
As described in detail above, the present invention, when coupled together, includes a fore-andaft barrel and a rear barrel that accommodates the entire microphone, and a leaf spring
tensioned into one or both of the barrels. A holder of the microphone attached to the leaf spring,
and the microphone supported by the holder is elastically supported, thereby causing the level of
the reproduction or recording not to be reduced. The main body (C can be safely stored, can be
used in recording in a wide range of fields, and has various effects such as being extremely
practical. ???
