Hereinafter, embodiments of the invention will be described with reference to the drawings. The present invention is not limited to the individual embodiments shown below, and can be carried out by changing the form.

FIG. 1 shows a sounding instrument 1 for support according to a first embodiment of the invention. In the figure, a part of the member is shown in cross section.
In the present embodiment, the support sounding instrument 1 is composed of a pair of, that is, two sound generating tubes 11 and 12. A sound is generated by bringing the sounding tubes 11 and 12 together. The support sounding instrument 1 may be provided with portions other than the sound tube, for example, a decorative cover, a handle, and the like. Further, the sound generation tubes 11 and 12 may be connected to each other by a string or the like.

The support sounding instrument 1 according to the present embodiment is used, for example, by holding each of the sound generation tubes 11 and 12 in both hands and meeting the sound generation tubes 11 and 12 together to generate a sound of support. it can.

The support sounding instrument 1 and the sound generation tubes 11 and 12 are typically made of synthetic resin, but may be made of other materials such as wood, paper, and metal. Typically, the support sounding instrument 1 of the present embodiment can be formed by blow molding or injection molding of a thermoplastic resin such as polyethylene resin or polypropylene resin.

The sound generation tubes 11 and 12 are members having a tubular portion formed in a hollow rod shape. The tubular portions 111, 112, 121, and 122 of the sound tube have resonance air chambers C1, C3, C2, in which the internal space of the tube communicates with the atmosphere, and air column resonance occurs at a predetermined frequency. C4 is configured.
The sound generation tube may have a non-tubular portion, for example, a solid plate-like portion. Further, the overall shape of the sound tube is not limited to a rod shape, and may be, for example, a box shape or a ring shape.

In the present embodiment, tubular portions 111 and 112 are provided in the first sounding tube 11 so that the first resonance chamber C1 and the third resonance chamber C3 are provided. The tubular portions 111 and 112 are formed into cylindrical hollow tubes having one end opened to the atmosphere and the other end closed, and the internal spaces of the tubular portions 111 and 112 are respectively connected to the first resonance air chamber C1. A third resonance chamber C3 is provided. Further, a plate-like portion 113 is provided so as to connect the closed sides of the tubular portions 111 and 112, and the rod-like sound tube 11 is configured as a whole.

Similarly, the second sound generation tube 12 is constituted by tubular portions 121 and 122 and a plate-like portion 123 connecting between the tubular portions 121 and 122. The tubular portion 121 causes the second resonance air chamber C 2 to be formed, and the tubular portion 122 provides the fourth resonance. An air chamber C4 is defined.

The first resonance chamber C1 to the fourth resonance chamber C4 resonate with each other at a frequency determined by the shape, volume, etc. of the resonance chamber. In each resonance chamber, air column resonance can occur at multiple frequencies. Of the resonance frequencies generated in each resonance chamber, the lowest resonance frequency is called the fundamental resonance frequency of the resonance chamber. That is, the first resonance chamber C1, the second resonance chamber C2, the third resonance chamber C3, and the fourth resonance chamber C4 resonate at the fundamental resonance frequencies F1, F2, F3, and F4 (Hz), respectively.

In the present embodiment, each of the resonance chambers (C1 to C4) has a so-called quarter wavelength resonance tube configuration, and the length of the resonance chamber (L1 to L4) is about the wavelength of the sound. Resonance is performed with a frequency corresponding to 1/4 as a fundamental resonance frequency. By adjusting the length of the resonance chamber, the fundamental resonance frequency can be adjusted. If the length of the resonance chamber is shortened, the fundamental resonance frequency increases.

The relationship between the basic resonance frequencies F1, F2, F3, and F4 set in the respective resonance chambers C1, C2, C3, and C4 will be described below.
Here, the plurality of basic resonance frequencies will be referred to as a first frequency, a second frequency, a third frequency, and a fourth frequency in order of increasing frequency. In this embodiment, since the lengths L1, L2, L3, and L4 of the resonance chambers C1 to C4 are L1>L2>L3> L4, the basic resonance frequency is F1 <F2 <F3 <F4. It has become. Therefore, in the present embodiment, the first frequency is the fundamental resonance frequency F1 of the first resonance chamber C1, the second frequency is the fundamental resonance frequency F2 of the second resonance chamber C2, and the third frequency is the third frequency. This is the fundamental resonance frequency F3 of the resonance chamber C3, and the fourth frequency is the fundamental resonance frequency F4 of the fourth resonance chamber C4.

The resonance chambers C1 and C2 are adjusted so that the sound of the first frequency (F1) is a root sound and the sound of the second frequency (F2) has a pitch of 3 degrees long. A pitch of 3 degrees long with respect to the root sound means that the frequency F2 satisfies the relationship F2 = 1.26 * F1 with respect to the frequency F1 of the root sound. For example, when the sound of the first frequency is a sound having a pitch of Seo (G) (for example, 196 Hz), the sound of the second frequency having a pitch of 3 degrees is a sound having a pitch of S (B) (for example, 247 Hz). Alternatively, for example, when the sound of the first frequency is a sound having a pitch of (C) (for example, 262 Hz), the sound of the second frequency having a pitch of 3 degrees is a sound having a pitch of Mi (E). (For example, 330 Hz). Note that an error may be allowed in this relationship.

When there are three or more resonant air chambers, the resonant air chamber C1 is further set such that the sound of the first frequency (F1) is the root tone and the sound of the third frequency (F3) has a complete pitch of 5 degrees. , C3 is preferably adjusted. A pitch of 5 degrees completely with respect to the root tone means that the frequency F3 satisfies the relationship F3 = 1.50 * F1 with respect to the frequency F1 of the root tone. For example, when the sound of the first frequency is a sound of the So (G) pitch (for example, 196 Hz), the sound of the third frequency of the complete 5 degree pitch is a sound of the pitch of (D) (for example, 294 Hz). Alternatively, for example, when the sound of the first frequency is a sound having a pitch of de (C) (for example, 262 Hz), the sound of the third frequency having a perfect fifth is a sound having a pitch of Seo (G). (For example, 392 Hz). Note that an error may be allowed in this relationship.

When there are four or more resonance chambers, the resonance chamber C1 is further set so that the sound of the first frequency (F1) is the root tone and the sound of the fourth frequency (F4) is at a pitch one octave above. , C4 is preferably adjusted. The pitch being one octave higher than the root note means that the frequency F4 satisfies the relationship F4 = 2.00 * F1 with respect to the root note frequency F1. For example, when the sound of the first frequency is a sound having a pitch of So (G) (for example, 196 Hz), the sound of the fourth frequency having a pitch one octave above is a sound having a pitch of a high So (G) ( For example, 392 Hz). Or, for example, when the sound of the first frequency is a sound having a pitch of Do (C) (for example, 262 Hz), the sound of the fourth frequency having a pitch one octave above is a pitch of a high Do (C). Sound (for example, 524 Hz). Note that an error may be allowed in this relationship.

In this embodiment, all the resonance air chambers are configured as quarter-wave resonance tubes having an inner diameter of 30 mm, the resonance air chamber C1 has a length L1 = 432 mm, and the basic resonance frequency F1 is 196 Hz. The resonance chamber C2 has a length L2 = 340 mm and a fundamental resonance frequency F2 of 247 Hz, and the resonance chamber C3 has a length L3 = 284 mm and a fundamental resonance frequency F3 of 294 Hz. The resonance chamber C4 has a length L4 = 211 mm and a fundamental resonance frequency F4 of 392 Hz.

The operation and effect of the support sounding instrument of the above embodiment will be described. The support sounding instrument 1 generates sound when the sound generation tubes 11 and 12 are struck against each other. At this time, the sound generated is remarkably generated at the fundamental resonance frequencies F1, F2, F3, and F4 of the resonance chambers C1, C2, C3, and C4. In the above embodiment, F1 = 196 Hz (So, G) as a root sound, F2 = 247 Hz (B, B), a long third degree sound, F3 = 294 Hz (Le, D), a perfect fifth degree sound, F4 = 392 Hz A plurality of sounds called octave sounds (high slew, G) are generated simultaneously. Then, these sounds become so-called major G chords called Seo, Shi and Les.

A chord that is a combination of a root tone, a long third tone, and a perfect fifth tone is a so-called major chord chord and a harmonious chord. On the other hand, a chord formed by combining a root tone, a minor third tone (a sound that is 1/12 octave lower than a major third tone), and a perfect fifth tone is a so-called minor chord chord.
The chords of major chords are brighter and more positive than the chords of minor chords.

Therefore, like the support sounding instrument of the above-described embodiment, by configuring the support sounding instrument so that the root sound and the long third sound are emitted simultaneously, the tone of the sounding sound generated is a major code. Like a chord, it gives a brighter, more active, positive impression. Since the sound of cheering is pronounced in such a tone, the feeling of the cheering athlete and the cheering spectator is more inspiring and exciting, so the cheering effect is enhanced. In the prior art, no consideration was given to the pitch, so the sound produced by the percussion instrument is merely a collection of sounds of various frequencies, and is like noise. Positive images such as concentration and aggressiveness were not actively communicated. On the other hand, a positive image can be actively conveyed with support by pronouncing the root sound and the third long sound in combination.

The perfect fifth sound relative to the root is not essential, but it is preferable that the perfect fifth sound is also pronounced at the same time. When a perfect fifth sound is pronounced in addition to the long third, the chords will sound with a clearer harmony and the support effect will be enhanced. Even if there is no resonance air chamber (resonance air chamber C3 in the above embodiment) that emits a sound of 5 degrees at the fundamental resonance frequency, if the resonance air chamber is a simple tube, the root sound is Since the second and third resonance frequencies of the resonant air chamber that emits the frequency are exactly three times the root tone, a sound that is exactly one octave above the complete fifth degree sound is emitted, and as a result is close to a major chord The sound of a chord is obtained.

In order to further enhance the psychological effect of cheering, chords of major G (so, shi, les) and major C can be obtained by using a sounding instrument for cheering with the root sound as seo (G) or de (C). It is particularly preferable that a chord of (Do, Mi, Seo) is pronounced. The chords of major G and major C are chords that are frequently used in the brightly tuned parts of music, and are particularly effective in psychologically engaging athletes and spectators in terms of cheering up their feelings. It is done.

As in the present embodiment, the resonance chamber C1 that emits the sound of the first frequency F1 and the resonance chamber C2 that emits the sound of the second frequency F2 are provided in different sound generation tubes 11 and 12, respectively. It is preferable. Since the first frequency and the second frequency are the first or second lowest frequency among the basic resonance frequencies of a plurality of resonance air chambers, the resonance air chamber that generates such a sound tends to be large. If the resonance chamber C1 that emits the sound of the first frequency and the resonance chamber C2 that emits the sound of the second frequency are provided in different sound generation tubes, even if the resonance chambers become longer, they are for support The overall length of the sound hitting instrument 1 can be suppressed, and the portability and handleability of the sound hitting instrument can be improved.

From the viewpoint of improving the portability and handleability of the sounding device, the resonance chamber C1 that emits the sound of the first frequency is a quarter wavelength resonance tube as in this embodiment, or will be described later. It is preferable to use a Helmholtz resonator as in the embodiment. Compared with a half-wavelength resonant tube with both sides of the tube open, a quarter-wavelength resonant tube with one end of the tube open and the other end closed has a resonance chamber for setting the same fundamental resonance frequency. The total length is reduced to about half, and the total length of the resonance chamber C1, and thus the total length of the sounding instrument can be suppressed. A Helmholtz resonator is advantageous because the overall length of the resonance chamber C1 is further suppressed.

Moreover, it is preferable that a plurality of resonance air chambers are provided for one sounding tube as in the support sounding instrument of the present embodiment. You can make chords by generating many sounds at the same time. In addition, when there are a large number of resonance air chambers, the root tone, the long third sound, the complete fifth sound, the sound one octave above the root sound, the sound one octave above the long sound, the perfect five degrees In order to produce a harmonious major tone chord, it is preferable to select the fundamental resonance frequency of the resonance chamber from the sound one octave above. At this time, the same sound may be generated in a plurality of resonance chambers.

Note that the degree of accuracy of the pitch of the root tone (F1), the long third tone (F2), the perfect fifth tone (F3), and the tone one octave above the root tone (F4) is strictly F2 = The relationship of 1.26 * F1, F3 = 1.50 * F1, and F4 = 2.00 * F1 does not have to be satisfied, and a slight frequency shift is allowed. It is preferable that the actual frequency is within ± 3% with respect to the target frequency, and it is particularly preferable that the actual frequency is within ± 1%.

The present invention is not limited to the above embodiment, and can be implemented with various modifications. Other embodiments of the present invention will be described below.
