[0005]

(First Embodiment) FIG. 1A is a perspective view of an electronic sound generator (electronic musical instrument) according to a first embodiment of the present invention, in which a part of the electronic sound generator is cut away. . The electronic sound generator includes a bottomed cylindrical main body case 1. A reticulated body 2 is provided in an opening on the upper surface of the main body case 1, and a speaker 3 is provided in an upper part of the main body case 1 inside the reticulated body 2. A handle 4 is provided at the center of the lower surface of the main body case 1. A power switch 5 and a plurality of tone generation mode selection switches 6 described later are provided on the outer peripheral surface of the handle 4.

Next, FIG. 1B is a sectional view taken along the line BB of FIG. 1A. A rotation shaft 7 is rotatably provided at a central portion in the main body case 1. Although not shown, the upper and lower ends of the rotating shaft 7 are rotatably supported by support plates provided in the main body case 1 via bearings. The base end of the connecting rod 8 is attached to a predetermined position of the rotating shaft 7. A spherical movable contact 9 having a certain weight is provided at the tip of the connecting rod 8. A plurality of fixed contacts 10 are provided at a constant pitch on a predetermined circumference in a portion corresponding to the movable contact 9 on the inner peripheral surface of the main body case 1.

When using this electronic sound generator, the handle 4 is gripped and the wrist is rotated in either direction. Then, the movable contact 9 rotates in the rotation direction of the wrist due to the centrifugal force together with the connecting rod 8 and the rotating shaft 7, and the movable contact 9 comes into contact with the plurality of fixed contacts 10 and then separates. Then, based on the on / off of the movable contact 9 and the plurality of fixed contacts 10, a musical tone is generated from the speaker 3 as described later. In this case, the operation in this case may be such that the wrist is rotated only once in any direction at a certain speed, that is, with the strength being applied. Alternatively, the wrist may be rotated in any one direction at a certain speed, then slowly returned in the other direction, and then rotated in one direction at the same speed, and the above operation may be repeated. Further, the wrist may be rotated at one speed in one direction and then loosely returned in the other direction, and then rotated faster or slower in one direction.

Next, FIG. 2 shows a main part of a circuit of the electronic sound generator. This circuit including the battery (not shown) is provided in the main body case 1 shown in FIG. When the power switch 5 shown in FIG. 1A is turned on, a voltage of + V is applied to the movable contact 9 via the rotating shaft 7 and the connecting rod 8. The plurality of fixed contacts 10 include, for example, each tooth portion of a comb-shaped contact member,
The detection signal input unit 2 is electrically connected to each other, and the entire on / off signal due to the contact / separation with the movable contact 9 is a pulse signal.
1 to the CPU 22.

The CPU 22 has a ROM 23, a RAM 24, a switch input unit 25,
A sound source 26 and the like are connected. ROM23 is
This is a memory in which a program for performing circuit control is written, and has a tone table to be described later. The switch input unit 25 is an input unit for inputting sound mode data from a plurality of sound mode selection switches 6 shown in FIG. The plurality of sounding mode selection switches 6 are used to select a tone or the like, and are, for example, a maraca sound selection switch, a tambourine sound selection switch, a sound effect selection switch, a clap sound selection switch, a yam sound and a cheering sound selection switch. . The RAM 24 temporarily stores the sound generation mode data and the like selected by the plurality of sound generation mode selection switches 6. The sound source 26 generates tone data in accordance with the data from the CPU 22 and outputs the tone data to the speaker 3.

Now, the movable contact 9 and the plurality of fixed contacts 1 will be described.
It is assumed that the entire on / off signal due to the contact / separation with 0 is a pulse signal shown in FIG. That is, in contact with the fixed contact 10 there is a movable contact 9 at the time from the time point of time t ₂ time t _1, then contacting the movable contact 9 and the next fixed contact 10 at the time of time t ₄ from the time of time t ₃ and, then the movable contact 9 is further in contact with the next fixed contact 10 at the time from the time point the time t ₆ of time t _5. CPU
22, when the pulse signal is input, calculates a time Tb of the time Ta from the time point of time t ₁ to the point of time t _3, the time point of time t ₃ to the point of time t _5, these time The data Ta and Tb are temporarily stored in the RAM 24.

The CPU 22 first searches the tone table in the ROM 23 based on the time data Ta. As shown in FIG. 4, the tone table in the ROM 23 stores a predetermined range of time T 1 to n (the range of time T is, for example, 0.01 seconds ≦ T <0.02 seconds. When a certain range satisfies 0.01 seconds ≦ T <0.02 seconds, the next range satisfies 0.02 seconds ≦ T <0.03 seconds, and increases by a fixed time.) (Data ₁₁ to data _1n ), pitch parameter (data ₂₁ to
Data _2n ), tone length parameters (data ₃₁ to data _3n ),
Tempo parameters (data ₄₁ to data _4n ) are set. In this case, the time T decreases as the rotation speed of the movable contact 9 increases, and the numbers (1 to n) indicating the range decrease as the time T decreases. Then, as the number (1 to n) indicating the range of the time T becomes smaller, the sound volume, the pitch and the tempo increase, and the sound length becomes shorter. When the time T is shorter than the range indicated by the numeral 1, the sound is generated by each parameter in the range indicated by the numeral 1, and when the time T is longer than the range indicated by the numeral n, the musical tone is generated. No sound is generated, or the sound is muted when a musical sound is being generated.

The CPU 22 searches the tone table in the ROM 23 and finds that, if the time data Ta falls within any of the preset ranges 1 to n of the time T, the CPU 22 outputs the corresponding parameter data to the tone generator. 26, and at the same time, supplies the tone generation mode data selected by the plurality of tone generation mode selection switches 6 to the sound source 26. The tone generator 26 generates tone data in accordance with the supplied parameter data and tone mode data, and the speaker 3 generates a tone in accordance with the tone data. That is, when the sound generation mode selected by the plurality of sound generation mode selection switches 6 is, for example, a maraca sound mode, a maraca sound is emitted.

Next, the CPU 22 performs a predetermined process based on the time data Tb. First, time Tb is equal to time T
When the speed is substantially the same as a, the rotational speed of the movable contact 9 is substantially the same, so that the volume, pitch, length, and tempo of the maracas sound emitted from the speaker 3 do not change and continue as it is. Secondly, when the time Tb is shorter than the time Ta, the rotational speed of the movable contact 9 is increased, and therefore, a number (1 to 1) indicating the range of the time T from the tone table of the ROM 23 based on the time data Tb. Each parameter data where n) is smaller than the previous time is read, and the volume, pitch and tempo of the maracas sound emitted from the speaker 3 are increased, and the sound length is shortened. Third, when the time Tb is longer than the time Ta, the rotational speed of the movable contact 9 is reduced.
Numerical values (1 to 1) indicating the range of time T from the 23 tone tables
Each parameter data where n) is larger than the previous time is read, and the volume, pitch and tempo of the maracas sound emitted from the speaker 3 are reduced, and the sound length is increased.

When the sounding modes selected by the plurality of sounding mode selection switches 6 are the harsh sound and the cheering sound mode, if the rotational speed of the movable contact 9 is lower than a certain speed, the harsh sound (booming sound). Sound), and if the speed is higher than a certain speed, a cheering sound is generated. Also in this case, the volume, pitch, length, and tempo are changed in the same manner as in the above case. Therefore, for example, when the rotational speed of the movable contact 9 is changed from a speed lower than a certain speed to a speed higher than a certain speed, the shouting sound (booming sound) gradually decreases and disappears, and then a cheering sound is generated and gradually decreases. Will grow larger.
