DETAILED DESCRIPTION OF THE INVENTION 1 Conventional sound collectors are portable
devices because the devices with large value of use 1 are t-shaped and bulky and bulky. Because
of that, it was not used much other than experts. 1 This invention is an improvement over this
shortcoming of the original sound collector. That is, 1 form was made into a cylindrical shape,
and one microphone 1, 1,...) X was made to be able to be stored and carried by 1 '1. □、
R*%i! 1, -q41 o 7 ky 'VCJ: ° 1 "" 111, but aperture 61. It has a length of about 12 to 15
and is remarkably smaller than the conventional sound collector. 1-1-1 FIG. 1 is a perspective
view of the present invention, which is a plastic cylindrical shape. In the figure, 1 is an opening,
and the sound collected in this is amplified by the inside of the cylinder 6 while being inserted
into the microphone insertion port 2 in the figure. The microphone is usually stored in a cylinder
5 hollow from the opening and used as a microphone case. This sound collector is about 2 ab
lower in the 200H2 to 500H2 range than in the box-like one with an aperture diameter of about
18 am, but the characteristics in the other high range have a performance that is as variable as y.
. There is no difference in the sound collection characteristics between the opening face and the
back and side, but this drawback is on the other hand the advantage of being able to sketch
sketchy and dumb sounds for recordings in conference rooms, outdoor scenery etc. It has
become. The noise specific to my father's cylindrical sound collector is also recorded, but it is not
enough to disturb the recording. This sound collector is a popular recorder, the sound of wild
birds and insects, 2-light Y7! (+ '-. Degree.) (E) It is useful for enjoying the recording of a small
conference, etc., and it seems to be useful for spreading the enjoyment of sound recording with a
sound collector to the general public.
