DESCRIPTION JPH09233589
[0001]
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a
sound collector for a microphone in which voice and other sounds are efficiently input to a
microphone, and a microphone with a sound collector attached thereto.
[0002]
2. Description of the Related Art In the case of using a microphone, part of the sound disperses in
four rounds before entering the microphone, so the sound entering the microphone is reduced
accordingly.
[0003]
SUMMARY OF THE INVENTION The conventional microphone has the following problems. .
When speaking on the street or singing a song in karaoke, if the volume is low, the sound is
dispersed before entering the microphone, so the microphone is surrounded by hand to prevent
the dispersion of the sound. However, this was troublesome because it had to be surrounded by
one hand. In addition, because people who are not aware of the method can not surround the
microphone with their hands, the sound is dispersed as in the past. . In order to increase the
volume input to the microphone, a person with a small amount of voice may forcibly loudly
damage the throat. In addition, when the voice is too loud, there is a problem that the sound is

broken, distorted, and difficult to hear.
[0004]
An object of the present invention is to provide a microphone sound collecting tool and a
microphone with a sound collecting tool for preventing dispersion of sound transmitted to a
microphone.

According to a first aspect of the present invention, there is provided a sound collecting tool for a
microphone according to a first aspect of the present invention, wherein the mounting portion 2
is attachable to and removable from the periphery of the microphone head 1 as shown in FIGS.
And a sound collecting unit 3 for collecting the sound entering the head 1 when the microphone
head 1 is worn.
[0006]
Among the present inventions, the microphone with a sound collecting tool according to claim 2
surrounds the microphone sound collecting tool 4 according to claim 1 around the head portion
of the microphone 1 as shown in FIGS. 2 (a) and 2 (b). It is something which is attached.

so as to be able to surround the periphery of the microphone head 1, and the mounting unit 2 is
formed below the same.
The sound collection unit 3 makes it easy to collect sound if the upper opening 5 is spread
outward, but if it is too wide, it picks up sounds (noises) other than the sound to be input, so the
upper opening 5 collects necessary sounds. Choose an area that is appropriate for sounding.
The height of the sound collection unit 3 is set to a height projecting above the top of the
microphone head 1 so as to increase the sound collection efficiency. If the height of the sound
collection unit 3 is too high, the sound collected by the sound collection unit 3 is attenuated
while propagating through the sound collection unit 3 and the volume of sound reaching the
microphone head 1 decreases. Make the sound collection unit 3 not too high. For example, it is
desirable that the distance from the top of the microphone head 1 to the upper opening 5 of the
sound collecting unit 3 be approximately 1 to 3 cm. The material of the sound collection unit 3 is
a material that is efficiently transmitted to the microphone head 1 without distortion or excessive
reflection of the sound collected by the sound collection unit 3, for example, plastic, wood,
rubber, Molded with metal, cork, etc. The sound collecting unit 3 can also be formed into a shape
or structure in which the collected sound resonates in the sound collecting unit 3.
[0009]
The mounting portion 2 formed below the sound collecting portion 3 is for attaching to the
handle 6 of the microphone, and is gradually thinned from the side of the sound collecting
portion 3 toward the lower end, and the inner diameter of the sound collecting portion 3 is the
grip 6 The inner diameter of the lower end side is slightly smaller than the outer diameter of the
handle 6 so that the outer peripheral surface of the handle 6 is gradually brought into close
contact with the inner peripheral surface of the sound collector 3 when the handle 6 is inserted.
It is The length of the mounting portion 2 is such that it can be attached to the handle 6.
[0010]
[Second Embodiment of the Sound Collector for Microphone of the Present Invention] The
second embodiment of the microphone equipped with the sound collector for microphone of the
present invention will be described in detail based on FIGS. 2 (a) and 2 (b). Do. In this case, the
sound collecting unit 3 and the mounting unit 2 are formed in a sheet shape, and fasteners 7

such as Velcro (registered trademark) detachable from each other are attached to respective
width direction ends, and the sheet sound collecting is performed. Round the part 3 in a
cylindrical shape around the microphone head 1 and bond the fasteners 7 at both ends together
to hold it in a cylindrical shape, and similarly wind the mounting part 2 around the periphery of
the handle 6 of the microphone When the fasteners 7 at both ends are bonded and held in a
cylindrical shape, they can be attached to the microphone. Also in this mounting, the opening 5 is
formed above the sound collecting unit 3. The sound collecting tool 4 mounted on the
microphone can be removed from the microphone when the adhesion between the mounting
tools 2 and the locking tools 7 of the sound collecting unit 3 is released.
[0011]
[Third Embodiment of the Sound Collector for Microphone of the Present Invention] Another
example of the sound collector for microphone according to the present invention will be
described in detail with reference to FIG. In this configuration, the sound collecting unit 3 is
