DESCRIPTION JP2009267661
An object of the present invention is to provide a microphone whose operation state can be easily
checked without the user repeatedly producing sound, blowing his breath strongly, or hitting the
windshield of the tip of the microphone. SOLUTION: A test sound output means for outputting a
test sound capable of confirming whether it is in operation or not and an output control means
for controlling an output of the test sound are provided in the vicinity of a piezoelectric
conversion unit inside a microphone windshield. We built a microphone that can check the
operating status in the same way as the usage status. [Selected figure] Figure 1
Microphone with operation confirmation function
[0001]
The present invention relates to a microphone having a function that allows the user to confirm
the operating state of the microphone, that is, whether or not the sound to the microphone can
be properly transmitted to the speaker (loudspeaker).
[0002]
Heretofore, a microphone is what converts a user's input voice or the like into an electric signal,
and the converted electric signal is amplified by using an amplifier, a speaker, or other peripheral
device, and even a small voice input can be obtained. It becomes possible to output with a big
voice.

This microphone is used when a user gives a speech or speech in front of a large number of
people, such as lectures and wedding halls, and today, it is also common to use it when singing
music with a karaoke apparatus. The For example, Patent Document 1 discloses a technique for
boosting the atmosphere of a karaoke place using a plurality of types of sound effects recorded
in a microphone. However, most users, including karaoke users, repeatedly pronounce the
microphone test, check, etc., or blow their breath out, to check the operation status before using
this microphone. Also, I hit the windshield of the tip of the microphone. Japanese Patent
Application Laid-Open No. 07-298382
[0003]
However, there are some users who feel hesitation or feel embarrassed and can not be
pronounced in repeating the user's own voice as before. In addition, the act of strongly blowing
breath is not very hygienic, and furthermore, the confirmation method of striking the windshield
is the cause of its own failure or the damage of the speaker etc. by giving an impact to the
piezoelectric conversion unit inside the microphone. It may also be. Therefore, using the
technology of Patent Document 1, for example, it is possible to output an effect sound recorded
in advance in a microphone and check the operating state, but this transmits an electric signal
recorded internally. The output is made by using peripheral devices such as an amplifier and a
speaker to check the operation state, and it is not to check whether the sound to the microphone
is normally transmitted to the piezoelectric conversion unit. Therefore, as in the conventional
confirmation method, it is necessary to input its own voice and impact sound. Therefore, in the
present invention, in view of the above-mentioned conventional inconveniences, the user does
not repeatedly pronounce the voice, blow the breath intensely, or hit the windshield of the tip of
the microphone, and the operation state is easily achieved. The challenge is to provide a
microphone that can be checked.
[0004]
In view of the above problems, a microphone having a confirmation function of the operation
state according to the present invention means a test sound output unit for outputting a test
sound capable of confirming whether the operation state is in the vicinity of the piezoelectric
conversion unit inside the windshield; The above-mentioned subject is solved by providing the
output control means which controls the output of the above.

The microphone having the confirmation of the operating state according to claim 1 of the
present invention includes a test sound output unit that outputs a test sound and an output
control unit that controls the test sound output unit in the vicinity of the piezoelectric conversion
unit inside the windshield. By providing the user, the user does not repeat the utterance and the
microphone does not give an impact to the microphone, and the operating state can be
confirmed.
That is, by inputting the test sound to be output from the piezoelectric conversion unit inside the
windshield of the microphone, first, it is possible to confirm whether the piezoelectric conversion
unit is operating normally and when the piezoelectric conversion is normally performed. In the
same manner as in the general use state, it is possible to electrically convert the input voice and
use the peripheral device such as the speaker to check the operating state. Therefore, the user is
nostalgic, and he does not feel hesitation or embarrassment to repeat the "microphone test" and
"check" voices, and gives an impact, and a microphone failure or For example, even if the power
of the microphone is turned on, no sound can be output, because the speaker can be prevented
from being damaged and the operating state can be confirmed in the same state as in actual use.
The effect of being able to confirm whether the microphone itself is operating normally is
exhibited.
[0006]
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.
[0007]
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 and voice into an
electric signal, and the converted electric signal is amplified through an amplifier and output
from a speaker. Specifically, the microphone (1) is composed of an output control means (2) and
various functional means connected to this, and the output control means (2) is a piezoelectric
voice generated by the user. When input to the conversion unit (3), the sound pressure of the
input voice is converted into an electrical signal, and the converted electrical signal is output
using the infrared communication unit (7). Then, the electric signal output from the microphone

(1) is input to the amplifier, amplified, and output from the speaker. In addition, although the
present Example is demonstrated using the wireless communication by infrared rays
communication, it is also possible to use using the wired connection by a wire communication.
[0008]
Then, when the test sound output switch (4) is turned on by the user, the output control means
(2) of the microphone (1) uses the test sound output means (5) to output the voice in the test
voice memory. The test sound is controlled to output a test sound to the chip (6), and the output
test sound is input to the piezoelectric conversion unit (3) inside the windshield and converted
into an electric signal, and then through peripheral devices such as an amplifier and a speaker.
Output.
[0009]
Next, an external view of the microphone shown in FIG. 2 and a flow showing confirmation
processing of the operation state of the microphone will be described.
[0010]
FIG. 2 shows an external view of the present microphone, and the microphone of the present
invention has a grip (M7), a power switch (M1) for controlling ON and OFF of the power, and a
windshield (M2) The piezoelectric conversion unit (M3) is provided to convert the voice input
from the user into an electrical signal.
Then, in the vicinity of the power switch (M1), a test sound output switch (M4) is provided for
the user to check the operating state of the microphone, and when the user operates this, it is
recorded The test sound output unit (M5) outputs a test sound (for example, a voice such as
mike test or check or an impact sound such as pom-pom or ton-ton ), and the
output test sound is piezoelectric After being input to the conversion unit (M3) and converted
into an electrical signal, it is transmitted to the peripheral device using the infrared
communication unit (M6).

power supply of the microphone is monitored (S1), that is, it is monitored whether the user has
turned on the power of the microphone. When the power is ON and the test sound output switch
is turned on by the user (S2), the test chip is output from the voice chip (S3), and the output test
sound is input to the piezoelectric conversion unit. (S4), when the input test sound is normally
transmitted to the sound generator of the microphone, the test sound is output through the
peripheral device such as an amplifier and a speaker.
(S5)
[0012]
According to this microphone, it is possible for the user not to feel hesitation or embarrassment
to repeat the sound and to give an impact and to prevent the failure of the microphone and the
breakage of the speaker etc. Since the operating state can be confirmed in the same state as in
actual use, for example, whether or not the microphone itself is operating normally even when no
sound is output although the power of the microphone is turned on. You can check
