DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a harmonica having a body in which a plurality of sound holes are arranged in parallel, and each sound hole has a main body having two leads having different pitches.

[0002]

2. Description of the Related Art There is a harmonica called a 10-hole harmonica, which has 10 whistle chambers (sound holes).
The one whistle compartment is provided with a blowing sound lead and a sound absorbing lead, and emits different sounds at the time of blowing sound and at the time of sound absorbing, respectively. The pronunciation pattern is as follows.

[0003]

[Table 1] In the 10-hole harmonica, the first to sixth holes have higher sound absorption than the blowing sound, and the seventh to tenth holes have higher sound blowing than the sound absorption. Therefore, in the first to sixth holes, a bend effect is obtained at the time of sound absorption, and the seventh to tenth holes are used.
In the hole, a bend effect at the time of blowing noise is obtained. As described above, the sound between the blowing sound and the sound absorption tends to decrease in either high sound regardless of whether the sound is the blowing sound or the sound absorption. It is to be noted that the one that actually sounds is the lower lead. These sounds can be easily produced by a conventional 10-hole harmonica, and are currently used as bend playing techniques.

[0004] On the other hand, sounds other than the blowing sound, the sound absorption and the bend playing method shown in the above table cannot be usually obtained. However, a skilled player can produce sounds other than those shown in the table, and such a playing technique is called overblow or overdraw. D ♭ between the 7th and 8th holes and A９ between the 9th and 10th holes shown in the above table were obtained by overdraw, and E ♭ between the 1st and 2nd holes and 4-5th.
E ♭ between holes, G ♭ between holes 5-6, H ♭ between holes 6-7
Is obtained by overblowing.

[0005] However, the overblow playing technique or the overdraw playing technique can only be performed by a fairly skilled person. In addition, since it requires advanced techniques, there is no guarantee that a clear sound can always be produced, and the volume is low. The above table is an example of the harmonica of the C-tone, but the same applies to other harmonics.

[0006]

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and an object of the present invention is to enable an overblow playing technique and / or an overdraw playing technique to be performed relatively easily. Sound and / or overdraw sound can be clearly pronounced at a sufficient volume.

[0007]

[SUMMARY OF] To solve the above problems the present invention, lead and each one vent independent leading to吹音leads, and each one vent independent leading to sound absorption leads The same number is formed, and an opening is provided outside each ventilation path, and by controlling the vibration of each lead by opening and closing the opening, the sound-absorbing lead can be sounded by blowing, and the sound-absorbing lead can be sounded by sucking. It is a means of doing it.

The present invention can be applied to the above-described 10-hole harmonica, but is not limited thereto, and can also be applied to other types of harmonica.

[0009]

DETAILED DESCRIPTION OF THE INVENTION A harmonica 10 according to the present invention comprises:
A plurality of sound holes 11 are arranged in parallel, and each sound hole 11 includes a main body 14 having two leads 12 and 13 that emit sounds having different pitches. Each of the leads 12, 13 is attached to an upper plate 15 and a lower plate 16 for lead attachment, and has a certain musical scale.
This scale may be the same as that of the C-tone 10-hole harmonica, for example.

One of the two leads 12, 13, for example, the upper lead 12 is a blowing sound lead made to emit a sound when blown, and the lower lead 13 is a sound lead when sucked, for example. It is a sound-absorbing lead made to give out. During performance, the airflow passes through each sound hole 11 to vibrate the reeds 12 and 13.

Each of the sound holes 11 is provided outside the main body 14.
And the same number of independent air passages 17 and 18 as the number of the sound holes 11 are formed. The positions of the air passages 17 and 18 and the sound holes 11 coincide with each other as well as the number. In the figure, reference numeral 19 denotes a partition wall between the adjacent ventilation paths 17, 17, 18, and 18. Each of the ventilation paths 17, 18 is provided so as to communicate only with the sound hole 11 at that position and not to leak to the other. .

The ventilation passages 17 and 18 can control the vibration of the leads 12 and 13 by opening and closing the passages. In other words, if a part of the ventilation passages 17 and 18 is closed, the flow of the air at that location stops, and the reed does not vibrate.
It can vibrate when blowing (or sucking). Therefore 1
The vibration of the two leads 12, 13 of the individual sound holes 11 can be controlled by opening and closing the ventilation paths 17, 18.

In the case of the illustrated embodiment, the outside of the main body 14 is surrounded by covers 21 and 22, and independent ventilation passages 17 and 18 communicating only with the sound holes 11 are formed in the covers 21 and 22. . Outer ends of the ventilation paths 17 and 18 are openings 23 and 24 that can be opened and closed with a fingertip. Exemplary openings 23, 24
Is assumed to be a 10-hole harmonica, so that the performance is facilitated by dividing it into two groups: a first hole to a sixth hole, and a seventh hole to a tenth hole.

In such a configuration, during a normal performance, the blowing lead 12 can be vibrated by blowing, for example, to produce a sound that should be originally obtained by the lead. This is the state shown in FIG. At this time, the lead 13 not used for blowing does not vibrate. Next, when the opening 23 of the ventilation path 17 in which the lead 12 is provided is closed, the air flow does not pass and the lead 12 cannot vibrate. However, the air passage 1 through the sound absorbing lead 13 which does not vibrate by blowing
8 is open, so that the exhaled air
Then, the lead can be evacuated to the opening 24, so that the lead can vibrate. This is the overblow according to the present invention, and the pitches obtained are the same as in the above table.

The same applies to the lead 13 for sound absorption, the state of which is shown in FIGS. 6 (a) and 6 (b).
In this case, by closing the sound-absorbing air passage 18 by closing the opening 24, the sound-breathing lead 12 is in a state capable of forcibly vibrating. This is the overdraw according to the present invention (FIG. 6 (b)), and the pitches obtained are the same as in the above table.

[0016]

The present invention is constructed and operates as described above. Since the air passages communicating with the respective leads are provided independently and the respective air passages can be opened and closed individually, the lead for blowing noise is provided. By vibrating the sound by the sound-absorbing operation and vibrating the sound-absorbing lead by the sound-blowing operation, the overdraw sound and the overblow sound can be surely emitted, and the airflow only passes through the specific ventilation path. Since the sound passes, the volume and the pitch can be easily adjusted, and an effect that a sufficiently loud sound can be output stably can be obtained.
