DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
[0007]
FIG. 1 is a block diagram of a pacifier type sound tool showing a first embodiment of the present invention, FIG. 2 is a schematic diagram of the pacifier type sound tool, and FIG. 3 is a diagram of a variable resistor with a knob showing the first embodiment of the present invention. It is a figure which shows a structure.
[0008]
In FIG. 1, the pacifier-type sound tool includes a pacifier part A, a knob part B, and a sound generation part C.
[0009]
Here, the pacifier part (corresponding to the pressure sensor) A and the knob part (variable resistor) B are connected to the sound generating part C in parallel. That is, since these signals are connected to the A / D converter C1 , a change in air pressure due to sucking the pacifier part A is detected by a pressure sensor, and based on this, a pressure-sound conversion process is performed to generate a sound. Can be generated.
[0010]
In FIG. 2, 1 is a baby nipple made of silicon rubber, 2 is rubber packing, 3 is a support, 4 is a vinyl tube, 5 is a pressure sensor, 6 is a sound generator, 7 is a plastic knob, and 8 is a variable resistance. It is a vessel.
[0011]
In this embodiment, the pacifier portion A uses nursing nipple 1 made of silicone rubber which is fixed to by Ri支 jig 3 in rubber packing 2 is connected to a pressure sensor 5 by vinyl tube 4. A pressure sensor 5 detects a change in the air pressure in the vinyl tube due to sucking the baby nipple 1. In consideration of safety, the length of the vinyl tube 4 is increased to separate the electrical system from the nipple.
[0012]
As shown in FIGS. 2 and 3, the knob portion B uses a plastic knob 7 and a variable resistor 8 to detect the rotation angle.
[0013]
The sound generation section C is the voltage change of the output from the pressure sensor 5 and the variable resistor 8, and digitized by infusionsystems Co. A / D converter [I-CUBE Digitizer] C1, MIDI [Musical Instrument Di g ital Interface (Computer)] Convert to information. Its MIDI information processed by computer programming on (Apple Corp. Computer PowerMac) C2 environment Max (Cycling74 companies) to produce a sound by the sound generator C3.
[0014]
There are two types of relations between actions and generated sounds depending on the stage of growth of the user.
[0015]
The first one (Application 1) is both a basic part consisting of the scales of only typical chords C, E, and G, which are said to be preferred even by infants shortly after birth, and another part separated by one octave. The pitch of the sound was made to correspond to the change in the suction pressure, and when it was sucked strongly, a higher sound was heard.
[0016]
This is because each time a part is sucked, the sound of one part is shifted by 5 semitones, so each time sucking is repeated, a consonant sound and a dissonant sound are repeated. It can be used from the early stages of growth because it can enjoy sound changes even with reflex sucking movement.
[0017]
The second (application 2) is intended for ages 1 and older who begin to acquire a tonality schema (unconscious knowledge about tonality) so that infants can perceive rhythms and melodies to some extent appropriately. A melody engraved with a simple rhythm created based on the tonal structure of Western music begins to flow, and when it stops, the melody is stopped. The suction pressure and the music tempo are associated with each other, and the tempo increases as the user sucks strongly. In both cases, the turning angle of the knob is associated with five types of timbre patterns.
[0018]
Actually I was asked to experience the present invention to the girls and their parents of much that has not been to the mouth of the pacifier 9 months, girls are viewed in addition the first Meoshaburi to mouth, did not try to almost suck . However, after about 15 minutes, I gradually got used to the pacifier and seemed to notice the causality between the change in sound and movement. I kept sucking while letting it go. Whether or not the test subject was able to notice the change in the timbre pattern caused by the father turning the knob could not be seen this time, but it was clearly enjoyable interaction.
[0019]
The following recording is a video image of what kind of reaction the girl is given with the sound tool of the present invention.
