BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a cross-sectional view showing an embodiment
of the present invention. FIG. 2 is a partially cutaway front view showing another embodiment of
the present invention. FIG. 3 is a perspective view of FIG. 2 with the sound quality control screen
attached. Fig. 1 Fig. 2 51 1st place
[Detailed Description of the Invention] The present invention relates to the omnidirectional and
unidirectional microphone 1 and the rophone, which can arbitrarily change the sound collection
angle when using unidirectionality. It is. In the prior art, it is necessary to produce two types of
unidirectionality, one, and no directivity from the design stage, and the disadvantage that the
noise is collected to unnecessary noise because it is omnidirectional Had. The present invention
provides an omnidirectional microphone having the above-mentioned drawbacks, which can be
used for both unidirectionality and also can freely adjust the directivity angle, and provides a
simple combination microphone which can be easily operated without increasing the cost. S, b,
pziCl) 48-39925 Next, referring to the embodiment of the drawing, in FIG. 1, the microphones
are transparent to the fronts of the microphone outer casings (2) and (2a) and the outer
microphone di (2a). A microphone element protected by a cap (4) having a hole is provided, and
the front face of the microphone outer case (2a) protrudes outward to be a stopper for the hood
(3C), and the hood (3a) (3b) (3C) The both ends of the two arms project in opposite directions,
and become nut-tailed when stretching each hood. )-I,-2 x ", b: d, 2". 7;::/、? 73a) (3t ·)
(3C) is housed outside the microphone iiI (2a) to remove the influence of ambient noise etc, any
finger can be used as the '' directional hood (3a) (3b) (3b) (5c) Pull to 1. In addition, the
directivity of the microphone characteristics is given, and the directivity of the person in the first
factor is the characteristics when using any two of the hoods (3a, 3b, 3t,); b, BU3 It shows the
case where each hood is used. The embodiment of FIG. 2 corresponds to the directivity variable
hood (2) jH14QO 9 + 1. -Nn (3a) (3b) (3C) is made into the hood (3) of a single member, the
other structure and effect are the same as that of the above-mentioned example at all. In the
embodiment shown in the figure # 13, a thread is provided inside the front of the variable
directivity hood (3), a screen frame (4) having the same diameter as the screw diameter is
attached, and a liver passing through the inner surface of the screen frame (4) Adjust the area, or
dampen the impact sound. A screen (4a) made of a sound-permeable material such as "", ti [lt · g
′ ′ ′, ttf! 0011″′′11″カ′;7. When it is desired to give a feeling, the screen (4 ·)
is replaced with one having a narrow pass range, a wide one and a nuclean that suits the
purpose, so that the sound quality can be easily adjusted. The present invention is configured as
described above, and even a simple device can be used as a nondirectional or unidirectional
microphone for both directions, and it is possible to use a directional device without causing
problems such as nails in terms of sound quality. You can also change the sex angle7.
