DESCRIPTION JP2009278404
PROBLEM TO BE SOLVED: In a wireless microphone using FM waves and infrared rays, a
microphone maintenance person or a user does not need to remove a windshield one by one
immediately, and in a normal charging operation, the interior of the windshield is automatically
automatically required without any special operation. It is an object of the present invention to
provide a microphone that can disinfect and disinfect bacteria. SOLUTION: A microphone
maintenance person or a user removes a windshield by one by performing control of an
ultraviolet radiation means for radiating an ultraviolet ray having an antimicrobial action inside a
windshield of a microphone based on the start of charging from a predetermined charger. Soon
after, the inside of the windshield was automatically disinfected, and a microphone was
constructed that could be antibacterial. [Selected figure] Figure 1
Microphone with antibacterial function
[0001]
The present invention relates to a microphone having an operation function by charging, which
can properly perform the inside of the windshield.
[0002]
Conventionally, a microphone is used when a user gives a speech or a speech, such as a seminar
or a wedding hall, and today, it is also used when the user sings music in a karaoke box or the
like.

This microphone is used instead of a large number of unspecified users. The microphone head,
that is, the windshield is sprayed with saliva every time it is used by each user, and bacteria are
proliferated to cause offensive odor etc. In some cases, some users think that there is a hygienic
problem and they are reluctant to use a microphone. In Patent Document 1, short fibers are
provided on the surface of the upper half and lower half of the protector attached to the
windscreen of the microphone as a method for removing bacteria from such a microphone, and a
short decontamination agent is added to the short fibers. There is disclosed a technique for
obtaining a germ reduction and deodorizing effect by adsorption. Patent Document 2 discloses a
technique for sterilizing and deodorizing a microphone using a germicidal lamp attached to a
microphone stand. Patent Document 1: Japanese Patent Application Laid-Open No. 06-38287
[0003]
That is, in Patent Document 1, bacteria elimination / deodorization is performed using a
protector attached to the windshield of the microphone, and when the bacteria elimination /
deodorization effect is weakened, the case is dealt with by periodic replacement of the protector.
. Moreover, in patent document 2, a microphone is disinfected and deodorized using the
germicidal lamp attached to the exterior. However, in these conventional techniques, the inside of
the windshield is not reliably subjected to antibacterial treatment or eradication and
deodorization. First of all, although the outside of the windshield can be easily disinfected and
disinfected, the inside of the windshield can not be easily removed since the windshield must be
removed one by one.
[0004]
Therefore, in the present invention, in view of the above-mentioned conventional inconveniences,
in particular, in the microphone having an operation function by charging, the microphone
maintenance person or the user does not have to take off the windshield at a time. An object of
the present invention is to provide a microphone capable of automatically disinfecting and
decontaminating the inside of the windshield without using any operation.
[0005]
In view of the above problems, a microphone having an antibacterial function according to the
present invention refers to a microphone having an operation function by charging, such as a
wireless microphone using FM waves or infrared rays, and emits ultraviolet light having an
antibacterial action to a predetermined portion inside a windshield. The above-mentioned subject
is solved by being provided with the radiation control means which controls this ultraviolet

radiation means, if an ultraviolet radiation means and the charge start from a predetermined
charger are recognized.
[0006]
The microphone having an antibacterial function according to claim 1 of the present invention is
a microphone having an operation function by charging, control of radiation start and radiation
end of ultraviolet radiation means for emitting an ultraviolet ray having an antibacterial action to
a predetermined part inside a windshield. The microphone maintenance person or the user does
not need to remove the windshield one by one by performing charging based on the
predetermined charger automatically, without any special operation in the normal charging
operation. The inside of the windshield can be disinfected and disinfected and disinfected.
That is, since the antifungal inside the windshield is automatically carried out, there is no need
for human actions and the problem of hygiene is solved.
Therefore, even a user who has avoided using the microphone can achieve the effect of being
able to use it. In addition, it becomes possible to further increase the antibacterial effect inside
the windshield by providing a thin film having an antibacterial function activated by ultraviolet
radiation on substantially the entire inside of the windshield.
[0007]
In the following, a preferred embodiment of the microphone of the present invention will be
described, and first, a block diagram of the main components of the microphone shown in FIG. 1
will be described.
[0008]
FIG. 1 is a block diagram of the main components of the microphone (1) of the present invention.
The microphone (1) of the present embodiment converts the input sound or sound into an
electric signal, and the converted electric signal is outputted from the speaker amplified through
01-05-2019

the amplifier. It is a thing. Specifically, the microphone (1) is composed of various functional
means, and the output control means (2) is inputted when the voice uttered by the user is
inputted to the piezoelectric conversion unit (3). The sound pressure by the voice is converted
into an electric signal, and the converted electric signal is output using the infrared
communication unit (4). Then, the output electric signal is input to the amplifier, amplified, and
output from the speaker.
[0009]
In the present invention, when the user inserts the microphone (1) into a predetermined charger,
if the charging terminal portion of the microphone and the charging terminal portion of the
charger are in contact with each other, radiation is started when the charging operation is
started. When the control means (5) recognizes, for example, the microphone windshield is an
ultraviolet radiation means (6) consisting of a light emitting diode which emits an arbitrary
ultraviolet ray of a specific wavelength (for example, 360 nm) among the wavelengths 320 to
400 nm having antibacterial activity. It radiates inside. The light emitting diode is used because it
can efficiently emit the required spectrum for activation of the photocatalyst described later, and
the present invention is not limited to this, and a general germicidal lamp may be used. .
[0010]
Next, an internal configuration diagram of the present microphone shown in FIG. 2 will be
described.
[0011]
FIG. 2 shows the internal configuration of this microphone, and the microphone of the present
invention consists of a windshield (M1) and a grip part (M2) in appearance, and is inputted into
the windshield (M1) A piezoelectric conversion unit (M3) for converting sound pressure by voice
to an electric signal, and an infrared light emitting unit (M4) for converting the converted electric
signal to infrared light and wirelessly outputting are provided under the grip portion (M2) .
[0012]
Then, when the user inserts the microphone into the insertion portion (C1) of the charger, the
charging terminal portion (M6) of the microphone and the charging terminal portion (C2) of the
charger contact to start the charging operation.

If this charge start operation is recognized by the radiation control means (M7) via the
rechargeable battery unit (M5), the radiation control means (M7) activates a timer provided
therein, and the timer is preset. If the predetermined time (for example, 3 minutes) has been
measured, control is performed so that ultraviolet light is emitted to the inside of the windshield
(M1) for a predetermined time (for example, 30 minutes).
It should be noted that the reason for providing the standby state and for the timer to emit the
ultraviolet light after the predetermined time has elapsed is that it has not been temporarily
inserted into the charger if it has been in the inserted state for a while. After that, the charging
work will be done surely, and it can be assumed that the microphone will not be used for the
time being. In addition, a thin film (M9) having an antibacterial function on substantially the
entire surface of the windshield may be a generally known one, for example, titanium dioxide,
zinc oxide, cadmium sulfide, sulfide which is a semiconductor that causes photocatalytic reaction.
It is a fine particle coating agent such as zinc, and the antibacterial action is activated by the
emitted ultraviolet light. Note that the radiation control means (M7) does not measure a
predetermined time using a timer when the charging operation is recognized, and immediately
radiates the ultraviolet light inside the windshield (M1) using the ultraviolet radiation means
(M8). It does not matter. Further, the radiation may be ended simultaneously with the end of the
charging operation without setting the radiation time of the ultraviolet light.
[0013]
Next, FIG. 3 will be described with reference to a flow showing the ultraviolet radiation
processing and a diagram showing the ultraviolet radiation processing of FIG. 4 in time series.
[0014]
FIG. 3 is a flow showing the antibacterial process, and the user inserts the microphone into the
charger first to start the charging operation of the microphone (S1), and if a predetermined time
has elapsed from the start of the processing operation. (S2) The inside of the windshield is
irradiated with ultraviolet light (S3), and when the ultraviolet light is emitted for a predetermined
time (S4), the radiation is ended (S5).
[0015]
Next, FIG. 4 is a diagram showing ultraviolet radiation processing in time series, in which (A) is a
01-05-2019

pattern of emitting ultraviolet radiation after measurement for a predetermined time, charging
operation of the microphone is started, and charging operation is recognized by the radiation
control means The microphone is in the radiation standby state, and the radiation control means
measures the time from the start of the charging operation to the time when the timer is
predetermined and the start of the radiation of the ultraviolet light, and the radiation start time
(for example, "5 minutes") is reached For example, after the ultraviolet radiation means emits
ultraviolet radiation and emits ultraviolet radiation for a predetermined predetermined time (for
example, "2 hours"), the remaining charging time (for example, "6 hours") continues the charging
operation. Do.
Next, (a) is a pattern of emitting ultraviolet light after the start of the charging operation, the
charging operation of the microphone is started, and when the charging operation is recognized
by the radiation control means, ultraviolet light is emitted immediately by the ultraviolet light
emitting means, The radiation of ultraviolet light is performed until the charging operation of the
microphone is ended.
If the microphone is removed from the charger while emitting ultraviolet light, the emission may
be forcibly stopped.
[0016]
According to this microphone, a microphone maintenance person or a user can quickly remove
the windshield and can automatically disinfect the interior of the windshield without any special
operation in a normal charging operation. In the past, since the microphone maintenance
personnel had artificially deferred to sterilization / deodorization work (for example, sterilization
/ deodorization spray spray, etc.), the hygiene aspect due to the fact that sterilization /
deodorization could not be performed due to maintenance personnel's neglect or mistake. In the
present invention, in the present invention, the inside of the windshield can be reliably and
automatically antibacterial, and this problem of hygiene is solved, and it can be used even by the
user who has avoided using the microphone. It becomes possible.
