Description

The present invention mainly relates to an electronic percussion instrument toy useful for sound education in infants and prevention of dementia and dementia in the elderly.

Instead of a musical instrument toy that automatically plays the melody (melody) of a pre-stored piece of music as an electronic sound by operating a switch, the player hits the striking surface to produce a live striking sound, and each striking is performed once. In response to this, the electronic sounds of the music stored in advance are sequentially generated one by one, and the melody of the music can be played with the player's arbitrary rhythm (beat) along with the raw tapping sound. A percussion instrument toy devised as described above is described in Patent Document 1.

Jikkenhei 4-128792 Gazette

However, in the configuration of the percussion instrument toy disclosed in Patent Document 1, an electronic sounding device is built in the base (2), and about eight songs stored in the electronic sounding device can be switched to the song selection switch (22). ), But the only setting item that the player can select is the song title, and the striking surface (5) is only one place as a whole. (Performance) There is little change in interest, and I can't keep playing for a long time without getting bored.

In other words, it is a monotonous musical instrument toy in which the player cannot change the melody of the musical piece and plays only with the timing rhythm (how to hit) of hitting the striking surface portion (5) at one place. Since the position and number of striking surfaces to be used cannot be selected or changed, and the difficulty level is constant, it is wide for beginners to experienced players, and by playing (playing) repeatedly for a long time, the infant's sense of rhythm can be cultivated. Also, it cannot be used for rehabilitation, brain activation, and health maintenance in old people.

An object of the present invention is to improve such a problem, and in order to achieve the object, in claim 1, the player uses at least four types of performance requirements, such as volume and tone, song title, and number of performance buttons. The 1st to 4th push button switches for setting each,

A voice guidance that informs the procedure of the above setting by the push button switch, a program memory that stores the melody sound of the music, and

In response to the detection output signal of the push button switch, the voice guidance stored in the program memory is output as voice data to the voice synthesis LSI, while the melody sound of the music also stored in the program memory is used as MIDI data. A CPU that controls to output to a MIDI sound source processor,

It is equipped with a speaker that outputs the above audio data as analog audio and the above MIDI data as analog-converted music sound.

After the player sets the required performance items, the player taps the number of push button switches determined to be used as performance controls, and the CPU that receives the detection output signal stores the detection output signal in the program memory. The feature is that the melody sound of the music being played is output one by one and emitted from the speaker.

Further, in claim 2, a fifth push button switch for a rhythm musical instrument to be tapped as a performance operator is additionally installed, and the CPU receiving the detection output signal of the fifth push button switch outputs the rhythm sound of the rhythm musical instrument. It is also characterized in that each sound is output to the MIDI sound source processor and is emitted from the speaker.

In claim 3, the first to fourth pushbutton switches are given different colored colors that serve as their respective identifiers, and at the same time.

When the number of performance buttons to be used is set, only the fixed number of the pushbutton switches is displayed by emitting light in the colored color.

Further, in claim 4, the first and second push button switches of the first to fourth push button switches are provided with up buttons for raising the level and numerical value of the volume and tone, the song title, and the number of performance buttons to be used, which are the performance requirements. It also gives a selection function as a down button to lower,

The third push button switch is also provided with a function as a decision button for determining the settings of the above performance requirements, and is also provided.

The feature is that the fourth push button switch is also provided with a function as a performance button for generating a rhythm instrument sound.

According to the above configuration of claim 1, the player uses the first to fourth push button switches for the volume (strength) and timbre of the music, which are at least four types of performance requirements, the music title, and the number of performance buttons to be used (operated). As compared with the conventional technique disclosed in Patent Document 1 at the beginning, there is a lot of change in the interest in performance, and anyone can enjoy playing for a long time without getting bored.

In particular, the fact that the number of performance buttons to be used can also be set means that the difficulty level of performance can be obtained by tapping the push button switch based on the number of buttons. It can be used for the prevention of dementia and dementia in the elderly, rehabilitation, and maintenance of health by using it in homes and hospitals for the elderly.

Moreover, since the plurality of push button switches that set the above performance requirements also serve as performance buttons that are tapped as performance controls, the number of required parts can be reduced and the number of required parts can be reduced, which is excellent as an electronic percussion instrument toy. The mass production effect and widespread use can be obtained.

In that case, if the configuration of claim 2 is adopted, in addition to the number of the first to fourth push button switches to be used, the fifth push button switch for a rhythm (accompaniment) instrument (percussion instrument) is also tapped. By doing so, it is possible to output one melody sound and one rhythm sound (percussion instrument sound) from the speaker, which makes the game more and more varied and improves the playing technique. There is an effect obtained.

Further, if the configuration of claim 3 is adopted, the number of performance buttons to be used can be determined by the light emission / display of the colored color applied to each push button switch, and the required configuration is simple. It is enough, and there is an effect that even infants and elderly people can tap without mistake.

Further, if the configuration of claim 4 is adopted, not only the function of setting each performance requirement item in the first to fourth pushbutton switches, but also the numerical value (number) and level (step) for selecting or adjusting in the setting. ) Up button and down button selection functions are given to the first push button switch and the second push button switch, respectively, and the function as a decision button that determines the setting of the above performance requirements is the third. Along with being given to the push button switch, the function as a performance button for generating a rhythm instrument sound (beating instrument sound) is given to the fourth push button switch, so that the configuration is remarkably rationally simplified. However, in combination with the fact that the setting procedure is taught to the player by voice guidance, it is possible to provide an electronic hitting instrument toy that is easy and convenient for anyone to use.
