According to the speaker 10 of the embodiment described above, the following effects can be
achieved. That is, according to the above-described speaker 10, the case 12 has a resonance
space S3 different from the front space S1. Here, the front space S1 accommodates the speaker
main body 22, and the resonance space S3 functions as a resonator for resonating the audio
output of the speaker main body 22. As a result, in the resonance space S3, the sound output in
the front space S1 can be Helmholtz resonance in the resonance space S3, and the bass range of
16-04-2019
19
the output sound can be amplified to enhance the acoustic effect. In addition, in order to enhance
the acoustic effect, resonance is caused in the resonance space S3 different from the front space
S1 in which the speaker body 22 is accommodated. By this, even if dust or water enters from the
outside through the outside through the resonance space S3 to resonate, it is possible to
suppress the dust or water from directly entering the front space S1.
[0051]
Further, according to the above-described speaker 10, since the front space S1 is adjacent on the
upper side of the resonance space S3, even if dust or water infiltrates from the outside in the
space where the resonance space S3 communicates with the outside, It is possible to prevent
dust and water from entering the front space S1 from the resonance space S3 by the action, and
the dustproof and waterproof effect can be further enhanced. More specifically, according to the
above-described speaker 10, the case 12 and the resonance case 50 have a resonance space S3
separated from the front space S1 and the front space S1. As a result, the front space S1 housing
the speaker body 22 can be sealed, and the dustproof / waterproof effect of the front space S1
can be enhanced. On the other hand, since the resonance space S3 is separated from the front
space S1 and adjacent to each other, the sound output from the front space S1 can be Helmholtz
resonated in the resonance space S3. By this, it is possible to amplify the low frequency range of
the sound to be output and to enhance the acoustic effect.
[0052]
Further, according to the above-described speaker 10, since the drone cone 55 is formed so as to
be able to vibrate upon receiving the sound output of the speaker main body 22, it is output in
the front space S1 by vibrating the drone cone 55. Sound in the resonance space S3 is easy to
make Helmholtz resonance. By this, it is possible to efficiently enhance the acoustic effect in
amplifying the low frequency range of the output voice. That is, according to the above-described
speaker 10, the resonance space S3 can exhibit the effect similar to that of the bass reflex
mechanism. Incidentally, according to the speaker 10 of the embodiment described above, an
effect of 3 dB amplification can be obtained at a frequency of 100 Hz. In addition, it was possible
to attenuate the inaudible frequency range lower than the audio frequency. As described above,
according to the above-described speaker 10, it is possible to output sound with high-quality
sound while enhancing the dustproof and waterproof effect.

Further, according to the above-described speaker 10, when the open / close cover 70 is closed,
the end edges 43, 72 of the case main body 40 and the open / close cover 70 are brought into
close contact with each other. A rubber packing 432 is provided. As a result, since the front
space S1 and the rear space S2 inside the case 12 are sealed when the open / close cover 70 is
closed, the dustproof waterproofness of the front space S1 and the rear space S2 inside the case
12 is enhanced It will be Here, the battery mounting portion 30 to which the power tool battery
B is mounted is internally mounted in the front space S1 and the rear space S2 inside the case
12, so that the battery mounting portion 30 or the battery mounting portion 30 is mounted. The
power tool battery B can be protected from dust and water, and the failure of the speaker 10
itself or the power tool battery B can be suppressed.
[0054]
Further, according to the above-described speaker 10, since the resonance space S3 is set to be
able to accommodate the portable electric device T, for example, a relatively large portable
electric device such as a 6-inch smartphone may be accommodated. it can. This is convenient
because storage of such a portable electric device T can also be performed. Further, according to
the speaker 10 described above, the dustproof and waterproofness inside the resonance space S3
can be enhanced by the open / close door 80. Here, the opening / closing door 80 is provided
with an opening 83 for allowing the resonance space S3 and the outside air to pass through, so it
becomes easier to cause the Helmholtz resonance in the resonance space S3 closer to the bass
reflex mechanism. As a result, the portable electric device T can be stored while enhancing the
dustproof and waterproof properties, and the Helmholtz resonance of the resonance space S3
can be secured, and voice output with high sound quality becomes possible.
[0055]
Further, according to the speaker 10 described above, since the lockable key hole 88 is provided
in the open / close door 80, theft prevention of the portable electric device T stored in the
resonance space S3 by locking the open / close door 80 Can be Further, according to the abovedescribed speaker 10, since the open / close door 80 is provided with the cord extraction portion
84 capable of extracting the cord C to the outside from the resonance space S3, the cord C
connected to the first connector portion 931 Can be drawn into the interior of the resonance
space S3. This makes it possible to charge the portable electric device T stored in the resonance
space S3, which is convenient. Further, according to the above-described speaker 10, the case 12
16-04-2019
21
is provided with the operation panel unit 26 which enables the operation of the portable electric
device T through wireless communication, so that input is performed from the operation panel
unit 26. Thus, for example, the portable electric device T stored in the resonance space S3 can be
operated. This makes it possible to operate the portable electric device T while keeping it stored
in the resonance space S3, which is convenient.
[0056]
The battery type voice output device according to the present invention is not limited to the
above-described embodiment, and various modifications can be appropriately made. For example,
the structure of the case 12 is not limited to the above-described substantially cubic shape, and
an appropriate shape can be selected. At this time, the case 12 described above is not limited to
the configurations of the case body 40 divided into three, the front frame 20, and the opening /
closing cover 70, and an appropriate divided configuration can be selected. In addition, in the
resonance space S3, it may be provided adjacent to the upper position of the front space S1, or
may be provided at the upper and lower middle position in the front space S1. . Even in such a
structure, since the open / close door 80 is located above the ground surface in contact with the
elastomers 292 and 69, the dustproof and waterproof property in the resonance space S3 is
enhanced. Further, in the battery type voice output device according to the present invention, the
resonance case 50 may be configured without providing the drone cone 55.
[0057]
That is, the drone cone 55 that separates the first internal space and the second internal space
may be excluded so as to be adjacent to and in communication with the first internal space and
the second internal space. That is, provided that the first internal space and the second internal
space are provided in the case 12 as a space that can be functionally divided, the first internal
space and the second internal space are provided in the case 12 so that they partially
communicate with each other. It may be Even in such a configuration, the first internal space and
the second internal space are set in different spaces, so even though the second internal space
resonates, it communicates with the outside to resonate. Even if dust or water enters from the
inside, dust or water does not immediately enter the first internal space. In addition, a labyrinth
structure may be provided as appropriate when configuring the second inner space according to
the present invention. For example, the ventilation part of resonance space S3 of the abovementioned embodiment is set as the back end in which door 80 exists. Here, when the resonance
space S3 leads to the front space S1, the resonance space S3 leads from the resonance space S3
to the front space S1 in front of and above the resonance space S3. In other words, when
16-04-2019
22
communicating from the outside through the second internal space to the first internal space, it
does not simply become straight and leads, but communicates through the labyrinth structure.
Dust and water can be made hard to invade from the 2nd interior space to the 1st interior space
by this. Furthermore, in a state where the drone cone 55 is abolished, a suitable second internal
space may be set between the open / close door 80 and the first internal space to be used as a
resonance space. Therefore, if configured in this way, the problem to be solved by the present
invention can be solved. The above-described speaker 10 is provided with an open / close door
80 for opening and closing the resonance space S3 to the outside. For this reason, it is possible to
suppress that dust and water enter the resonance space S3 immediately.
[0058]
Also, an appropriate shape can be selected as the shape of the resonance case 50. That is, in the
above-described embodiment, the configuration in which the first internal space and the second
internal space are separated is the second box-shaped member 61. Also, the drone cone 55 acts
to separate the first internal space and the second internal space. However, the configuration for
separating the first internal space (spaces S1 and S2) and the second internal space (resonance
space S3) is not limited to such a configuration. That is, as long as the first internal space and the
second internal space are separated or separated from each other including the functional
meaning, an appropriate configuration can be selected regarding the shape and the material.
[0059]
Further, in the above-described embodiment, since the battery mounting portion 30 is provided,
the front space S1 and the rear space S2 are partially communicated. However, an appropriate
partition may be provided between the front space S1 and the rear space S2, and the space may
be separated from each other. That is, the first internal space according to the present invention
is a space accommodating at least an audio output unit, and the third internal space according to
the present invention is a space where at least a battery mounting unit is installed. The structure
of may be added, or it may be configured to be connected to other spaces. Furthermore, in the
battery-type voice output device according to the present invention described above, power may
be supplied from a household AC power source as well as the power tool battery.
