Specifically, when the mother speaks to the infant as “Oishi-ne-ne” Is. FIG. 9 is a graph in which the fundamental frequency characteristics are plotted, and FIG. 10 is a graph in which the sound pressure, that is, the loudness of the sound in FIG. 9 is plotted.
[0018]
In particular, as shown in FIGS. 9 and 10, the frequency is a voice belonging to a range of approximately 200 Hz to 500 Hz, and is shown at a relatively high pitch (frequency). (Basic sound).
[0019]
As shown in FIGS. 9 and 10, this frequency is a changing sound that changes within a relatively short sound length of 1.4 seconds, and changes within a range of about one octave. Yes.
[0020]
Further, referring to FIGS. 11 to 13, the overtone structure of Mazalies can be understood. That is, as shown in FIG. 11, this sound has not only the sound of S1 corresponding to FIG. 9, but also a harmonic structure such as a second harmonic S2, a third harmonic S3,. FIG. 12 is a graph showing the frequency scale of FIG. 11 changed, and is a diagram for easily understanding the state of the basic sound S1 and the state of its harmonics. FIG. 13 is a graph in which the data of FIG. 10 is processed to show a gentle change.
[0021]
From these characteristics, it can be said that Mazalies are voices having the following characteristics.
(1) A voice having a high pitch, that is, a high frequency (basic frequency = F0) (corresponding to a basic sound referred to in the present invention) and a high key sound.
(2) A voice having a large difference in height and changing frequency, and a sound rich in intonation (corresponding to a change sound of the present invention).
(3) It has a harmonic structure and is therefore a sound that resonates well (corresponding to the synthesized sound in the present invention).
In addition, in order to talk to an infant, it is often a word utterance that does not have a sentence structure. And the silence time (latency) between one utterance and the next utterance is relatively long. In addition, there is a rising sound in which the ending frequency increases.
[0022]
Next, the configuration of the Mazaise similar sound generation apparatus 10 will be further described focusing on the configuration for generating the Mazalies having such characteristics.
This similar sound generation device 10 is a device for generating Matheries by a mechanical technique. Since Matheries is a voice of a mother who is an infant childcare person as described above, reference is made to a human voice function. It is configured.
Body 11 and the blower means 13 ie, described above, the human lung is composed following the feed out function air. Further, the sound generation means is a human vocal cord formed by a mechanical configuration as will be described later. The resonance means corresponds to a vocal tract including an oral cavity, a nasal cavity, and a pharynx where human voice resonates.
[0023]
As shown in FIGS. 1 to 3, the main body 11 is, for example, a wooden body, and is a housing having an internal space SP <b> 1 in which air sent out by the air blowing means 13 is accommodated.
An opening is formed in the upper part of the main body 11, and a blower means 13 is connected thereto. The air blowing means 13 is a bellows formed of a flexible material such as a vinyl material, and the lower end of the bellows is continuous with the internal space SP1 of the main body 11 as shown in the figure. These are arranged in the vertical direction in the figure and are contracted by manually pushing in the direction of the arrow in FIG.
[0024]
An opening 11a is provided on one side of the main body 11, and a sounding means 14 is formed facing the opening 11a. This sounding means 14 is a so-called artificial vocal cord.
The sound generating means 14 has a support body 19 attached to the opening 11a and a sheet-like vibrating body 18 fixed to the support body 19 with a predetermined tension.
[0025]
This sounding means 14 is shown in detail in FIGS.
4 is a schematic perspective view of the sound generation means, FIG. 5 is a schematic plan view thereof, FIG. 6 is a side view of a support body constituting the sound generation means, and FIG. 7 is a plan view of the support body.
First, as shown in FIG.6 and FIG.7, the support body 15 of the sound production | generation means 14 is provided with the short cylindrical part 15b. As shown in FIG. 7, the cylindrical portion 15b is narrowly bundled in the middle, and a support portion 15e having two inclined surfaces 15c and 15c whose tip side is gradually reduced in width is formed. An opening 15a is formed in each of the inclined surfaces 15c and 15c of the support portion 15e, and the opening 15a communicates with an opening inside the cylindrical portion 15b to form a ventilation hole. And the front-end | tip part 15d is obstruct | occluded. As shown in FIGS. 2 and 3, the support 15 is formed in a mortar shape in which the open side is gradually widened.
[0026]
Furthermore, a vibrating body 18 having a shape along the shape of each inclined surface 15c, 15c is fixed to each inclined surface 15c, 15c of the support portion 15e by means such as adhesion. Here, as shown in the figure, the vibrating body 18 is a sheet-like member having a shape corresponding to each of the inclined surfaces 15c, 15c, and is integrated by a connecting portion 18a. A locking hole is formed in the connecting portion 18a.
The sheet-like vibrating body is preferably made of an elastic material such as vinyl chloride, silicon, or elastomer, and a slight gap 18b or 18b is provided between the supporting body 15 and the sheet-like vibrating body. The opening 15a is closed so as to maintain a predetermined tension. Thereby, when air is sent by the air blowing means 13 described later, the sheet-like vibrating body 18 vibrates and emits sound at a frequency corresponding to the basic sound described above.
That is, the sound generating means is a sheet-like vibration that is fixedly disposed so as to close the ventilation holes and a pair of ventilation holes that guide the ventilation from the blowing means in a direction that is obliquely separated from each other, and changes the fixing tension. It has a body.
Such a sounding means 14 is fixed so that its cylindrical portion 15b is fitted into the proximal end opening 11a of the resonance means 12 as shown in FIGS.
[0027]
The resonance means 12 extends in a cylindrical shape, and an air hole 12a is formed in the upper part thereof. The air hole 12a plays a role corresponding to a nostril connected to the oral cavity of the human body.
Further, as shown in FIGS. 2 and 3, a frequency changing means 21 is provided. The frequency changing means 21 has a first rack 16 that is fixed to the inner surface of the upper end of the air blowing means 13 and extends in the vertical direction. A second pinion 17b that is engaged with the first pinion 17a, is fixed coaxially with the first pinion 17a, and is set to be decelerated is provided below the first rack 16. The second rack 17c meshes with the second pinion 17b, and the second rack 17c is fixed to the locking hole of the connecting portion 18a of the vibrating body 18 fixed to the support body 15. Has been.
[0028]
The present embodiment is configured as described above, and the following operation will be described.
The Mazarizu similar sound generation apparatus 10, below the hand of the user the top of the blowing means 13 from the state shown in FIG. 2, i.e. by pressing the arrow direction, the air of the interior space from entering the interior space SP1 of the main body 11.
Then, since the movement of the blowing means 13 stops at the bottom dead center of the bellows structure as shown in FIG. 3, the movement during this period corresponds to the sound length of the voice uttered. This sound length varies somewhat depending on the user's action. More preferably, this sound length is set in the range of 250 milliseconds to 600 milliseconds, and is set to, for example, about 400 milliseconds in this embodiment.
[0029]
Due to the action of the blowing means 13, the air in the main body 11 flows into the resonance means 12 through the sound generation means 14.
At this time, the air vibrates the vibrating bodies 18 and 18 while passing through the gaps 18b and 18b between the inclined surfaces 15c and 15c and the vibrating bodies 18 and 18 described with reference to FIGS. In FIG. 2, this vibration is set to a vibration corresponding to a frequency in the vicinity of, for example, 300 Hz when the air blowing unit 13 is started.
[0030]
Then, as the bellows of the blower means 13 is pushed, the first rack 16 descends in the direction of the arrow, and the first and second pinions 17a and 17b are rotated clockwise, whereby the second rack 17b. Will be raised.
As a result, the vibrating body 18 of the sound generating means 14 is pulled by the upward movement of the rack 17b and the tension is increased, so that the vibration frequency due to the passage of the air flow increases. That is, the frequency based on the vibration of the vibrating body 18 increases, and in the state shown in FIG. 3, the vibration is, for example, around 600 Hz set as the upper limit. In this way, the sound generation means 14 functions in the same way as when the human vocal cord continuously utters a changing sound that gradually changes to a high sound.
[0031]
As a result, the air density wave corresponding to the changing sound generated by the sound generation means 14 enters the resonance means 12 and resonates in the internal space SP2 so that the sound reverberates in the human oral cavity. As a result, overtones such as the second overtone and the third overtone are added to the basic sound.
[0032]
As described above, according to the Mazaise- like sound generation device 10, a sound having a basic sound of a predetermined frequency and its overtone structure and having a predetermined short sound length, that is, having a characteristic as a Mazarise, is generated. Will be.
The Mazaise-like sound generated by this device can particularly attract the attention of infants up to about six months of age, for example, and can be suitably applied to voice toys and the like corresponding to the development stage.
[0033]
Here, in comparison with the embodiment of the present invention, for example, compared with the sound of a soprano whistle (warp whistle) widely used in the past, the sound of a soprano whistle has a fundamental frequency F0 as high as about 520 Hz and is almost resonant. Does not have a harmonic structure. Moreover, a change sound cannot be produced unless a conscious operation is performed according to the scale, and since it is a scale, there is no continuous change. The toy whistle has been confirmed to have a voice characteristic such that the fundamental frequency F0 is even higher at about 850 Hz and resonance is not so much.
Therefore, in the apparatus of the present embodiment, it is possible to generate a sound that is much closer to the characteristics of the Matheries than these conventional whistle and toy.
[0034]
Further, according to the present invention, as described above, the following method may be executed using, for example, a synthesizer, without being limited to the method of generating the matheries using the mechanical configuration.
That is, a basic sound having a predetermined frequency is electronically set, a synthesized sound obtained by superimposing the harmonic overtone of the basic sound on the basic sound is set as a reference sound having a predetermined sound length, and the reference sound is approximately in an octave range. To create a rising and / or falling sound.
Alternatively, a basic sound having a predetermined sound length may be changed as a change sound that rises and / or falls within a range of approximately one octave, and a synthesized sound in which a harmonic overtone of the change sound is superimposed on the change sound may be generated.
[0035]
【The invention's effect】
As described above, according to the present invention, it is possible to provide a mazarise similar sound generation apparatus that can be used to generate mazalies that can attract attention of infants and to devise suitable toys and the like. it can.
