Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a toy musical instrument for children, particularly an animal-shaped keyboard instrument.

[Summary of the idea]

This idea is to attach a keyboard lid shaped like a part of the animal to the main body of an animal-shaped toy musical instrument, which is equipped with a keyboard and a musical sound generating means, so that it can be rotated between a position that covers the keyboard and a position that opens it. In this way, the keyboard is protected by the keyboard cover, and the opening and closing operations of the keyboard lid allow movement to be given to the animal.

[Conventional technology]

Conventionally, there have been animal-shaped toy instruments as keyboard instruments for young children, which have a musical instrument body in the shape of an animal such as a panda or an elephant, and are equipped with a keyboard and a musical sound generating means that generates musical sounds corresponding to key presses. .

[Problem that the invention attempts to solve]

However, such conventional animal-shaped toy musical instruments, which are keyboard instruments for children, do not have keyboard lids, so the keyboards are not protected and are often broken by rough handling by young children.

Another problem was that young children easily got bored with the animals because they did not move like animals.

This invention aims to solve these conventional problems.

[Means for solving problems]

Therefore, the animal-shaped toy musical instrument invented by this invention is
A musical instrument body in the shape of an animal, equipped with a keyboard and musical sound generating means, has a keyboard lid shaped like a part of the animal rotatably attached to a position that covers the keyboard and a position that opens the keyboard.

[Effect]

The animal-shaped toy musical instrument of this invention protects the keyboard by rotating the keyboard lid to a position that covers the keyboard when the keyboard is not in use, making it less likely to be broken.

Moreover, the movement of the opening and closing of the keyboard lid gives movement to the animal, which can increase the interest of young children.

〔Example〕

Hereinafter, embodiments of this invention will be described based on the drawings.

FIGS. 1a and 1b are diagrams showing an overview of a swan-type electronic keyboard instrument, which is an embodiment of this invention, with the keyboard lid closed and opened.

In this embodiment, a musical instrument body 1 is shaped like a swan, a keyboard 2 is provided in an arc shape on one side of the body, and a group of switches 3 for selecting and changing tone, volume, etc. is provided on the top of the keyboard 2. There is.

Further, a keyboard lid 4 in the shape of a swan's feather is attached to the main body 1 of the instrument via a rotating shaft 5, and is positioned to cover the keyboard 2 and switch group 3 as shown in FIG. 1a. As shown in Figure b, they are rotatably provided to the open position.

By opening and closing this keyboard lid 4, an internal power switch is turned on and off via a rotating shaft 5. When the keyboard lid 4 is opened as shown in b, the power switch is turned on. The LED 6 placed at the eye position lights up, illuminating the eye-shaped mask and changing from the closed eye state of a to the open eye state.

The musical instrument main body 1 also includes circuits constituting musical tone generating means for generating musical tones corresponding to key presses on the keyboard 2, which will be described later.

FIG. 2 is an external view similar to FIG. 1b of another embodiment of this invention, and FIG. 3 is an exploded perspective view showing an enlarged main part thereof.

This embodiment differs from the embodiment shown in FIG. 1 in that a memory pack 7 containing a ROM, etc. that stores automatic performance data is placed in a case shaped like a swan's tail at the rear end of the instrument body 1. This means that it can be attached and detached.

That is, as shown in FIG. 3, a plug 8 is provided protrudingly on the rear end surface of the musical instrument main body 1, and a jack 9 is recessedly provided on the front end surface of the memory pack 7, and by fitting the two, the memory pack 7 is attached to the musical instrument main body. 1 mechanically and electrically connected at the same time.

FIG. 4 shows another embodiment of this invention, which has an appearance similar to FIG. 1b, in which a hat-shaped memory pack 7' is removably provided on the head of the musical instrument body 1.

Next, an example of the circuit configuration of the musical tone generating means provided inside the musical instrument main body 1 in these embodiments is shown in the fifth example.
This will be explained using figures. Note that parts corresponding to those in FIG. 1 are given the same reference numerals.

10 is a power source such as a battery, 11 is a power switch that is turned on and off by rotating the rotation shaft 5, and 12 is an AND circuit that controls lighting of the LED 6.

13 is a key press detection circuit that detects which key on the keyboard 2 is pressed; 14 is a pronunciation assignment circuit that generates pitch (pitch name) data corresponding to the pressed key based on the detection signal; 15 is a memory pack 7; Alternatively, it is a readout control circuit that reads automatic performance data from 7'.

Furthermore, a selector 16 selects and outputs the data from the sound generation allocation circuit 14 and the data from the readout control circuit 15, a musical tone forming circuit 17 forms a musical tone signal based on the data, and a sound source consisting of an amplifier, a speaker, etc. A system 18 is provided.

Therefore, the function of this animal-shaped toy musical instrument as a keyboard electronic musical instrument will be explained.

When the power switch 11 is turned on, the signal a from the read control circuit 15 to the AND circuit 12 becomes "1" if the memory pack 7 or 7' is not installed.
Therefore, the output of the AND circuit 12 becomes "1" and the LED 6 lights up continuously. When the memory pack 7 or 7' is installed, the signal a from the read control circuit 15 to the AND circuit 12 becomes a pulse signal with a constant period, so that the LED 6 blinks.

If you operate the keyboard 2 with the selector 16 switched to the sound generation assignment circuit 14 side by the changeover switch SW of the switch group 3, the sound generation assignment circuit 14 will generate pitch data corresponding to the pressed key. , are input to the tone forming circuit 17 via the selector 16.

Thereby, the musical tone forming circuit 17 forms a musical tone signal of the tone selected by the switch group 3 and the pitch (frequency) corresponding to the input pitch data, and the sound system 18 amplifies it. The sound is converted into sound and produced by a speaker.

When the memory pack 7 or 7' is installed and the selector 16 is switched to the readout control circuit 15 side, the readout control circuit 15 reads automatic performance data from the memory pack 7 or 7' and inputs it to the musical tone formation circuit 17, so that data is Musical tones of pitches corresponding to the musical numbers are sequentially formed and sounded by the sound system 18, and the pieces of music whose automatic performance data are stored in the memory pack 7 or 7' are automatically played.

Note that this invention is applicable not only to keyboard electronic musical instruments but also to keyboard instruments in which the musical tone generating means is mechanical sounding means.

Also, the shape of the instrument body is not limited to this example, but can be shaped like any animal such as a dog, cat, elephant, or panda, and in that case, the keyboard lid can also be shaped to form part of that animal. do it.

[Effect of idea]

As explained above, the animal-shaped toy musical instrument according to this invention has an animal-shaped musical instrument main body that is equipped with a keyboard and musical sound generating means that constitute a keyboard instrument.
The keyboard lid, which is shaped like a part of the animal, is rotatably attached to a position that covers the keyboard and a position that opens it, so the keyboard can be protected by the lid when the keyboard is not in use. It will not break even if handled roughly.

In addition, since the movement of the opening and closing of the keyboard lid can be used to give movement to the animal, it not only increases the attachment and interest of infants and allows them to get used to keyboard instruments quickly, but also fosters a sense of animal welfare.
