The swing plate 16 has an elongated strip shape, and its right end is fixed on the printed circuit board 15, and its left end is spaced apart above the fixed contact 17. Therefore, since the magnet 14 is normally arranged on the bottom surface of the intake hole 10 as shown in FIG. In addition, when air flows into the intake hole 10 due to intake air, and the free end side of the flexible member 12 is pushed up elastically by this air flow, and the magnet 14 is pushed up accordingly, the second As shown in FIG.

20. A CPU (central processing unit) 22 which 21 inputs and outputs as a data signal 22a, and this CPU
22 data signals 22a, and an amplifier section 24 that amplifies the musical tone signal 23a output from the musical tone generating section 23.
The speaker section 7 generates musical tones based on the signal 24a output from the amplifier section 24.

Next, the operation of the electronic musical instrument configured as described above will be explained. First, when a performance is to be performed using the scale specifying hole section 3 of the electronic harmonica 1, the mode switching section 5 is set to the mouse mode and the mode signal 21 is inputted to the CPU 22 in advance. In this state, the user places his or her mouth on the scale specifying hole 3 and breathes through a desired hole among the intake holes 10 and the exhalation holes 11 arranged alternately in the order of the scale. At this time, for example, when air is inhaled through the intake hole 10 shown in FIG. 2, the air flows into the intake hole 10 due to the intake air, and this air flow causes the flexible member 12 to elastically expand at its free end side. , and pushes the magnet 14 upward. Then, the left end of the oscillating plate 16 on the printed circuit board 15 is attracted by the pushed-up magnet 14 and comes into contact with the fixed contact 17 . When the rocking plate 16 contacts the fixed contact 17 in this way, the contact signal output from the fixed contact 17 is transmitted from the harmonica body 9 to the CPU as a scale designation signal 19.
22. Then, the data signal 22a is outputted from the CPU 22 to the musical tone generating section 23, and the musical tone signal 23a generated by the musical tone generating section 23 is amplified by the amplifier section 24 and inputted to the speaker section 7 as a signal 24a. As a result, the speaker section 7
A predetermined musical tone, that is, a musical tone of a scale corresponding to the air intake hole 10 is produced.

For example, when breathing into the exhalation hole 11, the free end side of the flexible member 12 is deformed to elastically swell due to the flow of air due to exhalation, pushing up the magnet 14 and causing the exhaled air to flow. The swing plate 16 corresponding to the hole 11 is attracted by the magnet 14 and comes into contact with the fixed contact 17. In this way, the swing plate 1
6 comes into contact with the fixed contact 17, the harmonica main body 9 outputs the scale designation signal 19 corresponding to the exhalation hole 11 to the CPU 22 in the same way as described above, and a predetermined musical tone is emitted from the speaker section 7 via the above-mentioned path. .

In this way, according to the electronic harmonica 1, since breathing is used as an input means, even beginners can easily play input using the same playing method as a natural instrument using the conventional breathing playing method. The fly-out prevention member 9a prevents the magnet 14 from flying out.
Since the magnet 14 does not enter the mouth or throat, input performance can be performed safely and satisfactorily.

In the above embodiment, a mode switch is provided, and the electronic harmonica 1 and the mini electronic keyboard instrument 2 are
However, this embodiment is not limited to this, and it is possible to operate the electronic harmonica 1 and the mini electronic keyboard instrument 2 at the same time and output them from the harmonica body 9 and the keyboard section 4 at the same time. It is also possible to adopt a configuration in which each musical tone is generated simultaneously using the respective signals 19 and 20 generated. In this way, it is possible to play a melody on the electronic harmonica 1 and at the same time provide accompaniment on the keyboard section 4 to enjoy an ensemble performance.

Furthermore, this invention is not limited to the actuating member and switch member as in the above-described embodiment, but may be as shown in FIG. 4 or 5, for example. That is, the actuating member shown in FIG. 4 is composed of the same magnet 30 as in the above-described embodiment, but the magnet 30 is installed upside down inside the intake hole 10 and the exhalation hole 11 of the harmonica body 9, respectively. It is attached to the lower surface of the flexible member 12. Therefore,
Said magnet 30 is normally arranged on the top surface within each hole 10.11. Further, the switch member is a printed circuit board 15 arranged on the upper surface of the harmonica body 9.
A fixed contact 31 and a swinging plate 32 which is normally in contact with the fixed contact 31 and can be brought into and out of contact with the fixed contact 31 are provided on the lower surface thereof in correspondence with the intake hole 10 and the exhalation hole 11. Therefore, the swing plate 32 usually has the following structure, as shown in FIG. 4A.
Since the magnet 30 is placed in the upper part of each hole 10.11, it is attracted to the magnet 30 and the fixed contact 3
1 and not in contact with each other, and air flows into each hole 10.11 due to breathing, and this air flow causes elastic deformation of the flexible member 12 and the magnet 3.
0 falls, the rocking plate 32 returns with its own elastic force as shown in FIG. 4B, and the fixed contact 31
The fixed contact 31 outputs a contact signal. Even in this case, the same anti-jumping member 9a as in the above-mentioned embodiment is provided on each mouth side of the intake hole 10 and the exhalation hole 11. However, even with such an input device, there are effects that are exactly the same as those of the above-described embodiments.

Furthermore, the actuating member shown in FIG. 5 is one in which a rivet-shaped pressing member 40 is provided on a flexible member 12 disposed within the intake hole 10 and the exhalation hole 11, similar to the above-described embodiment. Yes, usually each hole 10.1
It is placed on the bottom side of 1. Also, a switch member that is switched by the pressing member 40
The SW has fixed contacts 41 formed of a pair of electrodes formed on the lower surface of the printed circuit board 15 disposed on the upper surface inside the intake hole 10 and the exhalation hole 11, and a spacer having an opening at a location corresponding to the fixed contact 41. 42, a protective layer 43 is provided on the lower surface of the spacer 42 to cover it, and a movable contact 44 is provided on the protective layer 43 so as to be able to come into contact with the fixed contact 41 through the opening of the spacer 42. There is. Therefore, in the switch member SW, as shown in FIG.
11, the movable contact 44
is spaced apart from the fixed contact 41, does not output a contact signal, and each hole 10.1 due to breathing
When air flows through the inside of the flexible member 12 and the pressing member 40 is pushed up due to the air flow, the movable contact 44 presses through the protective layer 43 as shown in FIG. 5B. Since it is pushed up by the member 40, it contacts the fixed contact 41 through the opening of the spacer 42, and a contact signal is output from the fixed contact 41. In this case as well, the intake hole 10
And, on each mouth side of the exhalation hole 11, a splash prevention member 9a similar to the above-described embodiment is provided. However, the input device configured in this manner also has the same effects as those of the embodiment described above.

In addition, in the above-mentioned embodiment and each modification thereof,
Although the elongated plate-shaped protrusion prevention member 9a is provided on the mouth side of the intake hole 10 and the exhalation hole 11, the elongated plate-like protrusion prevention member 9a is not limited thereto, and a wire mesh-like protrusion prevention member may be used. In addition, the intake holes 10 and the exhalation holes 11 are alternately
Although they are arranged in rows, they may be arranged in two or more rows, or may be provided with either one of the intake holes 10 or the exhalation holes 11 like a mouthpiece. Further, the switch member is not limited to the above-mentioned switch member, but may be any other switch member, and in short, the switch is operated by an actuating member that displaces up and down as the flexible member is elastically deformed. Good to have. The signals outputted from these are not limited to the scale designation signal 19 of the main note, but may be signals of derivative notes, or may be mere contact signals.

In addition, in the above-mentioned embodiment and each modification thereof,
Although the mini electronic keyboard instrument 2 is provided with a sound generation circuit such as the speaker section 7, this invention is not limited to this, and it is also possible to provide a sound generation circuit within the harmonica body and configure the musical instrument by itself. As mentioned above, it may also be used as an external musical instrument.

[Effect of idea]

As is clear from the above explanation, according to this invention, the actuating member fixed on the elastically deformable portion of the flexible member does not fly out from the open end of the scale note designation hole during intake. In order to prevent this, a pop-out prevention member having at least one member is spanned across the opening end, so that when inhaling, the suction preventive member is placed in the scale note designating hole. When atmospheric pressure is applied, the actuating member can be blocked by the above-mentioned popping-out prevention member. Therefore, since the actuating member does not accidentally fly out, the actuating member does not get stuck in the mouth or throat, resulting in excellent safety and good input performance.
