[0001]
TECHNICAL FIELD The present invention relates to an audible range sound and a speaker device
for outputting a high frequency sound that is higher in frequency than the audible range sound.
[0002]
In recent years, it has been clarified that there are various effects on the body, such as the feeling
of relaxation being obtained when bathed in a high frequency sound that is a high frequency (for
example, 20 kHz or more and 100 kHz or less) than the audible range sound. Is called the
hypersonic effect.
Since high frequency sound is more likely to be attenuated in space than audible range sound, a
10-05-2019

pendant type high frequency transmitter is considered so that each listener can obtain
hypersonic effect even in a wide space (see Patent Document 1) ).
[0003]
JP, 2010-081208, A
[0004]
However, in the conventional pendant type high frequency transmitter, it was not considered
about keeping the volume of the high frequency sound to output in a predetermined range.
If the volume of the high frequency sound is too small, even with the pendant type high
frequency transmitter attached, the hypersonic effect can not be obtained sufficiently. On the
contrary, if the volume of the high frequency sound is too high, there is a possibility that a side
effect may occur on the body.
[0005]
An object of the present invention is to provide a speaker device which can keep the volume of
high frequency sound to be output within a predetermined range.
[0006]

[0016]
Hereinafter, a shoulder type speaker device according to a first embodiment of the present
invention will be described with reference to the attached drawings.
The shoulder-type speaker of this embodiment is used in a state of being hung on the user's
shoulder, and based on an audio signal such as music transmitted from an external device such
as an audio playback device or a portable terminal, It is an output.

[0017]
As shown in FIG. 1, the shoulder speaker device 1 has a mounting portion 2 that can be mounted
by being hung on the user's left and right shoulders, and a left speaker portion 3 and a right
speaker portion attached to both left and right end portions of the mounting portion 2 4 and.
Note that “upper”, “lower”, “left” and “right” in the embodiment are based on the state
of being worn by the user.
[0018]
The left speaker unit 3 and the right speaker unit 4 are configured in substantially the same
manner, and each include an audible range speaker 5 and a high frequency sound speaker 6.
[0019]
As shown in FIG. 2, the audible range sound speaker 5 and the high frequency sound speaker 6
are each formed in a film shape.
The audible range sound speaker 5 and the high frequency sound speaker 6 are provided so as
to be superimposed one on the other, and both are integrated (see FIG. 2A).
By integrating the audible range sound speaker 5 and the high frequency sound speaker 6, the
left speaker unit 3 and the right speaker unit 4 can be made compact.
[0020]
The audible range speaker 5 outputs an audible range sound.
The audible range sound is, for example, a sound of 20 Hz or more and less than 20 kHz.
10-05-2019
5
As the audible range sound speaker 5, a rubber speaker in which a vibrating portion that
generates a sound is configured only by an expandable and conductive rubber can be suitably
used. Of course, the audible range speaker 5 is not limited to the rubber speaker, and various
configurations capable of outputting an audible range sound can be used.
[0021]
The high frequency sound speaker 6 outputs a high frequency sound that is higher than the
audible range sound. The high frequency sound is, for example, a sound of 20 kHz or more and
100 kHz or less. As the high frequency sound speaker 6, a piezo film speaker in which a resincoded piezo element and a resin film to which the vibration of the piezo element is transmitted
can be suitably used. Of course, the high frequency sound speaker 6 is not limited to the piezo
film speaker, and various ones capable of outputting high frequency sound can be used.
[0022]
The shapes of the audible range sound speaker 5 and the high frequency sound speaker 6 are
preferably thin such as a film or a plate from the viewpoint of mountability, but may be other
shapes.
[0023]
The audible range sound speaker 5 and the high frequency sound speaker 6 are superimposed
on each other with the sound output portion facing outward.
Therefore, the audible range sound output direction 5 a which is the sound output direction of
the audible range sound speaker 5 and the high frequency sound output direction 6 a which is
the sound output direction of the high frequency sound speaker 6 are contradictory. That is, in
the state where the shoulder-held speaker device 1 is attached to the user, the audible range
sound output direction 5a is directed substantially upward, and the high frequency sound output
direction 6a is substantially directed downward. Therefore, for the user, while wearing the
shoulder-held speaker device 1, the user can listen to the audible range sound with his / her ears
and can receive high-frequency sound with a body part other than the ear (for example, the
torso). With regard to the hypersonic effect, it is said that it is more effective to listen to a high
frequency sound with the ear, that is, to take it with a body part other than the ear rather than
taking it with the ear. It can be expected that you can get hypersonic effects more effectively by
10-05-2019

bathing with body parts other than your ears.
[0024]
In the above example, the audible range sound speakers 5 and the high frequency sound
speakers 6 are provided at the top and bottom of each other, but the arrangement is not limited
to this, and they are provided at the inside and outside of each other. (See FIG. 2 (b)). In this case,
the audible range speaker 5 may be inside or outside.
[0025]
The mounting portion 2 is formed in a substantially arc-shaped narrow plate shape. It is
preferable that the portion of the mounting portion 2 that comes into contact with the user's
shoulders and neck during mounting be made of a material having high flexibility and water
resistance.
[0026]
As shown in FIG. 3A, in the mounting portion 2, core members 7 are respectively embedded near
the left and right end portions. The core member 7 is made of, for example, a metal wire or plate
material, and has a plurality of bent portions 8 in the longitudinal direction. The core member 7
has a variable bending angle at each bending portion 8 and is configured to hold a bent shape.
The user can adjust the audible range sound output direction 5 a and the high frequency sound
output direction 6 a by bending the left and right core members 7. Thereby, the user can adjust,
for example, the audible range output direction 5a to be more toward the user's ear (see FIG. 4).
[0027]
FIG. 3 (b) is a view showing a modification of the mounting unit 2. The mounting part 2 which
concerns on a modification is replaced with the core member 7, and has the two hinge parts 9
provided in the front-end | tip part. The two hinge portions 9 rotatably support the left speaker
portion 3 and the right speaker portion 4 respectively. The user can adjust the audible range
sound output direction 5a and the high frequency sound output direction 6a by rotating the left
10-05-2019

speaker unit 3 and the right speaker unit 4 with the hinge unit 9 as a fulcrum. In addition, the
core member 7 and the hinge part 9 of this embodiment are an example of the "sound output
direction adjustment part" in a claim.
[0028]
Subsequently, a head-mounted speaker device according to a second embodiment of the present
invention will be described. The head-mounted speaker of the second embodiment is configured
substantially the same as the shoulder-mounted speaker device of the first embodiment, but the
head-mounted speaker of the second embodiment is a headphone type, and It differs from the
shoulder-mounted speaker device of the first embodiment in that it is used in a state of being
mounted on the head. Hereinafter, differences will be mainly described.
[0029]
As shown in FIG. 5, the head-mounted speaker device 101 includes a mounting portion 102
mountable to the head of the user, and two audible sound speakers 105 attached to both left and
right end portions of the mounting portion 102. A high frequency sound speaker 106 built in the
mounting unit 2 is provided.
[0030]
The mounting portion 102 is formed in a thin plate shape substantially in the shape of a “shoe
iron”.
It is preferable that the inside of the mounting portion 102, that is, the portion that hits the
user's head when worn, be made of a material that is highly flexible and water resistant.
[0031]
The audible range speaker 105 outputs an audible sound. The audible range speaker 105 is
attached to the mounting unit 102 so as to hit the user's ear when worn. As the audible range
speaker 105, for example, a rubber speaker can be suitably used as in the audible range speaker
5 of the first embodiment.
10-05-2019

[0032]
The high frequency sound speaker 106 outputs high frequency sound. The high frequency sound
speaker 106 is incorporated in the mounting portion 102 along the longitudinal direction of the
mounting portion 102. This allows the user to have a high frequency sound when worn, in a wide
area of the head, for example, from the right ear to the left ear through the top of the head. As
the high frequency sound speaker 106, for example, a piezo film speaker can be suitably used as
in the high frequency sound speaker 6 of the first embodiment.
[0033]
FIG. 6 is a block diagram showing a circuit configuration of the shoulder-hanging speaker device
1 of the first embodiment. The circuit configuration of the head-mounted speaker device 101
according to the second embodiment is the same as the circuit configuration of the shoulder-type
speaker device 1, and therefore, the shoulder-type speaker device 1 will be representatively
described below.
[0034]
As shown in FIG. 6, the shoulder-held speaker device 1 includes a signal input unit 11, a D / A
conversion unit 12, an audible range signal amplification unit 13, a high frequency signal
generation unit 14, and a high frequency volume control unit 15. The audible range speaker 5
and the high frequency sound speaker 6 described above are provided. In addition, the shoulder
type speaker device 1 is wirelessly connected to the external device 20. Of course, the shoulder
type speaker device 1 may be connected to the external device 20 by wire. Note that as the
external device 20, an audio reproduction device (for example, a CD player), a portable terminal
(for example, a smartphone), and the like can be mentioned.
[0035]
An audible range signal, which is an audio signal including an audible range, is input from the
external device 20 to the signal input unit 11. The signal input unit 11 outputs the input audible
10-05-2019
9
range signal to the D / A conversion unit 12. The audible range signal is a digitalization of
various sounds. As various sounds, music, sound effects, human voices, etc. are not limited. The
audible range signal may include a high frequency.
[0036]
The D / A conversion unit 12 converts an audible range signal input from the signal input unit
11 into an analog signal. The D / A conversion unit 12 outputs the audible range signal
converted into the analog signal to the audible range signal amplification unit 13 and the high
frequency signal generation unit 14.
[0037]
The audible range signal amplification unit 13 amplifies the audible range signal input from the
D / A conversion unit 12. The audible range signal amplification unit 13 outputs the amplified
audible range signal to the audible range speaker 5.
[0038]
The audible range speaker 5 outputs an audible range sound based on the audible range signal
input from the audible range signal amplification unit 13.
[0039]
The high frequency signal generation unit 14 generates a high frequency signal, which is a high
frequency sound signal, based on the audible range signal input from the D / A conversion unit
12.
The high frequency signal generation unit 14 outputs the generated high frequency signal to the
high frequency volume control unit 15. The high frequency signal generation unit 14 generates a
high frequency signal, for example, by frequency converting the input audible range signal. In
addition, when the audible range signal includes a high frequency, the high frequency signal
generation unit 14 may generate the high frequency signal by a high pass filter that passes a
predetermined frequency or more (for example, 20 kHz or more).
10-05-2019

[0040]
The high frequency volume control unit 15 controls the volume of the high frequency sound
output from the high frequency sound speaker 6 within a predetermined range. For example, the
high frequency sound volume control unit 15 detects the signal level of the high frequency signal
input from the high frequency signal generation unit 14, and amplifies the high frequency signal
input from the high frequency signal generation unit 14 according to the detected signal level.
The high frequency sound volume control unit 15 outputs the amplified high frequency signal to
the high frequency sound speaker 6.
[0041]
The high frequency sound speaker 6 outputs high frequency sound based on the high frequency
signal input from the high frequency volume control unit 15.
[0042]
As described above, according to the shoulder-held speaker device 1 of the first embodiment and
the head-mounted speaker device 101 of the second embodiment, the volume of the high
frequency output from the high frequency sound speaker 6 is controlled within a predetermined
range. By providing the high frequency sound volume control unit 15, the volume of the high
frequency sound to be output can be kept within a predetermined range.
Therefore, for example, when the user listens to a plurality of pieces of music, even if the signal
level of the audible area signal input from the external device 20 to the signal input unit 11 is
different among the plurality of pieces of music, the user is special The high frequency sound of
appropriate volume can be bathed in the body while listening to a plurality of music without
performing the operation. The “predetermined range” of the volume of the high frequency
sound is preferably a range of the volume in which the hypersonic effect can be sufficiently
obtained and which does not cause any side effect on the body.
[0043]
10-05-2019
11
Further, according to the shoulder-type speaker device 1 and the head-mounted speaker device
101, since the audible range sound is output from the audible range speaker 5, the user is not
only exposed to the high frequency sound but also the audible range sound. You can listen to
Therefore, it can be expected to obtain a more relaxed feeling.
[0044]
The shoulder-held speaker device 1 and the head-mounted speaker device 101 may be
configured to have a volume for adjusting the volume of the audible range sound. Of course, the
volume of the audible range may be adjusted on the external device 20 side. Even when the user
operates the volume to adjust the volume of the audible range sound, the high frequency volume
control unit 15 controls the volume of the high frequency output from the high frequency sound
speaker 6 within a predetermined range.
[0045]
In the present embodiment, as the speaker device of the present invention, the shoulder-mounted
speaker device 1 and the head-mounted speaker device 101 have been described as examples,
but the present invention is not limited thereto. It may be anything that can be attached to any
part.
