Sound equipment
[0001]
The present invention relates to an acoustic device worn on a body and used.
[0002]
In places where there is a large indoor space such as a university lecture hall, an acoustic system
is used in which the voice of a speaker is picked up by a microphone and the sound is amplified
from the speaker.
[0003]

In the conventional sound system, the speaker holds the microphone in hand, or holds it in
clothes like a tie pin, or fixes a part of the microphone with a string and hangs it from the neck.
For example, Patent Document 1 discloses a microphone that is used by hanging from the neck.
[0004]
Patent No. 4931907
[0005]
By the way, there are some problems with the conventional microphone mounting method.
For example, with a tie-pin type microphone or the microphone described in Patent Document 1,
there is a problem that sound adjustment, for example, adjustment of volume, is required each
time depending on the mounting method (position and orientation of the microphone).
[0006]
Further, in the conventional method, a sound generated when the microphone comes into contact
with the body due to the movement of the speaker or a sound of rubbing clothes may be
collected.
As a result, unpleasant noise may be generated in the amplified sound of the collected sound.
[0007]
FIG. 14 is a view showing a state where the conventional neck type sound device 3 is worn on
the body. This figure shows that the speaker is moving to the left and right. When the speaker
moves to the left or right, the position of the electroacoustic transducer 4 moves to the left or
right because the acoustic device 3 is hung from the neck by a string, and when it moves, it
makes rough noise when it touches the sound of clothes rubbing A contact noise is generated.

[0008]
Further, in the case of the conventional necking method, there is a problem that it is difficult for
some people to attach and detach. For example, FIG. 15 is a diagram showing a state in which the
conventional neck type sound device 3 is attached and detached. Depending on the person there
is a strong commitment to the hairstyle, it can be considered that the volume is up. In that case,
the wearing strap 3 is caught on the hair and the hair style is broken, which makes the speaker
feel unpleasant.
[0009]
The same problems as these are considered to occur, for example, when the speaker is worn on
the body in the conventional manner as described above. That is, it is conceivable that the
sudden movement changes the position of the speaker, and the sound sways, or that the speaker
can not perform the sound amplification in any direction in which it wants to sound.
[0010]
The present invention has been made in view of such circumstances, and an object thereof is to
provide an acoustic device which can be worn on the body and easily attached and detached
more stably than the conventional method.
[0011]
The acoustic device comprises an electro-acoustic transducer and a plurality of supporting
members provided to support the acoustic transducer, the supporting member extending in
different directions starting from the acoustic transducer, and the supporting member being the
body The electroacoustic transducer is configured to be positioned on the front of the chest of
the body when the acoustic device is attached to the body, and the support structure is
supported and fixed at at least two support points on the back and front of the body. It is
characterized by

two support points on the front and back of the body.
In addition, by having a support structure in which the electroacoustic transducer is positioned in
front of the chest of the body, when picking up a voice or the like, the voice can be reliably
picked up at a certain distance from the speaker's mouth, When the voice or the like is to be
loudened, it can be reliably voiced in the direction in which the human body is facing.
[0013]
Further, the acoustic transducer is characterized in that a connection portion of the
electroacoustic transducer with the plurality of support members is different from the support
point.
[0014]
According to this configuration, since the connection portion of the electroacoustic transducer
connected to the plurality of support members is different from the support point contacting the
body, the contact to the body or clothes can be avoided.
[0015]
Furthermore, the support member is characterized in that the shape is asymmetric with respect
to the acoustic transducer.
[0016]
According to this configuration, when the length of one of the support members is long, the
number of support points in contact with the body is increased, and stable fixation can be
realized.
Further, also when the width of the support member is wide, the point at which the support
member comes in contact with the body becomes wide, and stable fixation can be realized.
[0017]
In the case of an asymmetrical shape, the plurality of support members on the front of the body
01-05-2019

are characterized by having a support structure that can be fixed in common.
[0018]
According to this configuration, even if the back surface of the body is fixed by two support
points, the front surface can be supported by the common support point.
By doing so, stable fixation can be realized at fewer points.
[0019]
Further, the plurality of support members are characterized by being curved corresponding to
the shape of the body.
[0020]
According to this configuration, the plurality of support members can be curved along the shape
of the body, and can be fixed, for example, by hanging on the shoulders.
[0021]
The plurality of support members have at least two bending points between the acoustic device
and the ends of the plurality of support members, and the distance connecting the two bending
points is at least two of the ends of the support members. It is configured to be shorter than the
distance connecting the end points provided.
That is, the width is gradually narrowed from the inflection point toward the end.
[0022]
According to this configuration, the ends of the plurality of support members are provided in
pairs, and the acoustic device is fixed so as to be hooked on the back of the body.
01-05-2019
5
A plurality of support members can be hung on both shoulders from the front of the body, so
that easy installation can be realized.
Furthermore, also at the time of removal, it can be easily removed simply by removing the
support members hung on both shoulders from the shoulders.
[0023]
Furthermore, in this configuration, the width is wide around the chest where the audio device is
provided, and the sense of stability against the motion that twists the body is increased.
By narrowing from the chest through the shoulders to the ends of the support members on the
back, the movement of the shoulders is not affected.
Therefore, even if the shoulder is moved round and forth, the mounting stability of the device is
not affected.
[0024]
Furthermore, the plurality of support members include communication means for
communicating with an external device.
[0025]
According to this configuration, the acoustic device can transmit the generated electrical signal to
the external device or receive the electrical signal generated by the external device.
[0026]
The communication means is characterized in that the electric signal generated by the electric
signal converter is output in a form that can be received by an external device.
[0027]
01-05-2019

According to this configuration, it is possible to include signal output means for outputting the
electrical signal generated by the electrical signal converter in a form that can be received by the
external device.
The electro-acoustic transducer has a function of converting an input voice or the like into an
electric signal, and can output the converted signal to an external audio device such as an
amplifier or an audio mixer.
[0028]
Further, the communication means is characterized by receiving an input signal from an external
device, converting the input signal into an electric signal, and inputting the electric signal into the
electroacoustic transducer, contrary to the above signal output method.
[0029]
According to this configuration, the communication unit includes the signal input unit capable of
receiving a signal from the external device and converting the input signal into an electric signal.
The electro-acoustic transducer can convert an electrical signal input from an external device
into voice and the like and can spread the voice.
[0030]
As the communication means, for example, there is a wireless transceiver that transmits and
receives signals wirelessly.
[0031]
The acoustic device of the present invention can realize more stable body wearing and easy
attachment / detachment of the device than the conventional method.

When the acoustic device 10 is worn on the body, since the bending point 14 of the support
member is the maximum width (α ′ distance) as described above, the width gradually
decreases toward the end 12 (β ′ distance), When the width of the support member 11 is
slightly opened, it becomes easy to mount. (Α distance> α ′ distance, β distance> β ′
distance)
[0045]
According to this configuration, when the neck width of the speaker 1 is shorter than the β
distance during the attachment, the speaker 1 can not be attached, so that the speaker can be
worn by extending it to the β ′ distance longer than the width of the neck thickness. Do. If you
go back to β distance after wearing, you can wear more firmly to the body.
