Description

Ocarina

This creation is about a kind of ocarina, a kind of instrument that plays.

"Ocarina" is a small, easy-to-carry and easy-to-play instrument. In particular, its appearance can be varied and varied, so it is widely loved by the general public.

As shown in FIG. 1, the main structure of the general Ocarina 1 is composed of a mouthpiece portion 10, a sounding hole 11, a plurality of finger holes 12 and a resonance chamber 13, wherein the mouthpiece portion 10 is matched with a general person. The mouth shape is sized, and a blowing port 101 is formed between the opposite end edges 10a, 10b of the mouthpiece portion 10. The sounding hole 11 communicates with the resonance chamber 13, and an air passage 14 is connected between the air blowing port 101 and the sounding hole 11. . The air blowing port 101 is for compressing the blown air, so that the airflow is concentrated to the sounding hole 11 through the air passage 14, and a shunt is generated at the front end of the sounding hole 11, wherein one airflow enters the resonance chamber 13, and the other The airflow is split until the sound hole 11 is ejected to make a sound; if a different scale is to be generated, the finger pressure is pressed or released by fingering to change the air pressure between the resonance chamber 13 and the outside air, and different frequencies are formed. Resonance and tone.

The sound field of Ocarina is not wide, and the standard six-hole Ocarina 1 has six finger holes. The cloth position is four holes on the same side as the sound hole 11, and two holes on the back side. When playing, please refer to Figure 2, the thumb of the two hands is responsible for pressing the back two holes, and the other four holes are subject to The rest of the finger control; the midrange C ocarina can blow up to 12 degrees (ie Si to treble Fa), so some people have developed a double-cavity, three-cavity ocarina, in an attempt to expand its range, but in terms of construction It is complicated and increases the difficulty and cost of production. Therefore, if you can develop a new hole to expand the vocal range of the Ocarina, it will be a great boon for the user.

Furthermore, it has been experimentally proved that the sound field of the ocarina is also related to the magnitude or flow rate of the air flow through the air passage 14; however, in general, as shown in Fig. 1, the structure of the ocarina 1 is connected to the air outlet 101 to sound. The air passages 14 between the holes 11 have the same aperture. If an attempt is made to increase the air flow, it is nothing more than expanding the diameter of the air outlet 101 to absorb a large blow, and the diameter of the air passage 14 to be excavated is still the same as that of the air outlet 101. If the caliber is consistent, the flow rate of the airflow will be sacrificed, and the contribution to the extension of the Ocarina sound field is not high. In addition, increasing the diameter of the air blowing port 101 will inevitably interfere with the original size setting of the mouthpiece portion 10, and must be considered. Whether the mouth shape of the player is appropriate and bound by certain limits, otherwise it will cause difficulty in playing, which is a subject worthy of further discussion.

In order to expand the vocal range of the Ocarina, the creation system has a wedge-shaped air passage from the edge of the air blowing port toward the sound hole. The end of the air passage communicates with the sound hole and the resonance chamber, and the small air outlet of the small outlet is used as the air passage. When passing, it can increase the flow rate because it is instantaneously compressed. Through the technique of blasting or blowing, the highest sound can be reached to #Fa (and) even to Sol, bass to La (and) even to Sol.

In addition, the blow port of the present invention is formed from the one end edge of the mouthpiece portion obliquely toward the end of the mouthpiece portion; if so, the diameter of the blow port can be achieved under a fixed-size mouthpiece structure Maximize, in particular, it is not necessary to change the original design of the mouthpiece to help increase the intake air volume. If the wedge-shaped airway structure is combined, it will definitely help to expand the range and volume of the ocarina.

Furthermore, the creator has a seventh hole at a position on the back of the six-hole ocarina, which is farther away from the sound hole. The seventh hole is in the range covered by the movable thumb, and the seventh hole can be used to pass the standard six hole. Ocarina's highest range extends to #Fa (and) and even Sol, which enhances its practical value.

Please refer to the third to fifth figures at the same time, the Ocarina 2 of the present invention includes a shell portion 20 having at least one resonance chamber 21 therein; and a mouthpiece portion 22 connected to One side of the shell portion 20, and the end portion of the mouth portion 22 has a blowing port 221 for supplying airflow into the shell portion 20; a sounding hole 23 is provided on the shell portion 20 adjacent to the air blowing port 221. And intersecting with the resonance chamber 21; the plurality of finger holes 24 are distributed on the shell portion 20 and communicate with the resonance chamber 21; wherein a wedge-shaped air passage 25 is opened from the edge of the air blowing port 221 toward the sound hole 23, The end of the air passage 25 communicates with the sounding hole 23 and the resonance chamber 21, and the air passage 25 of the small design with such an entrance large outlet can increase the flow rate when the airflow passes, and is blown or blown by the Ocarina 2 Skills, you can reach the highest sound to #Fa (and) even Sol, bass to La (and) even Sol's range.

In addition to increasing the speed of the intake air flow, if you can increase the intake air volume at the same time, it will be more helpful to expand the Ocarina 2 sound range and volume. Preferably, the blow port 221 of the present invention is formed from the one end edge 22a of the mouthpiece portion 22 obliquely toward the end 22b of the mouthpiece portion 22; if so, it can be constructed in a fixed size mouthpiece portion 22. In order to maximize the diameter of the air blowing port 221, in particular, it is possible to help increase the amount of air intake without changing the original design of the mouthpiece portion 22. If the structure of the wedge-shaped air passage 25 is combined, the expansion of the Ocarette 2 is The sound field and volume are absolutely beneficial, and it is a very practical creation. It is a patent application.

Furthermore, please refer to FIG. 6 for another preferred embodiment of the present invention. A seventh hole 242 is opened at a position further away from the sound hole 23 in the back of the shell portion 20 of the standard six-hole Ocarette 2, and the seventh hole 242 is in a range covered by the player's active thumb. The seventh hole 242 can extend the highest pitch of the standard six-hole ocarina to #Fa (and) even the sound range of Sol, and further enhance its practical value.

The embodiment disclosed in the present application is only one of the preferred solutions, and is not used. To limit the content of the creation; the equivalent changes or retouching of the technical means and features of the creation should still be covered by the scope of the patents of the later articles.
