Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to an electronic wind instrument that allows a player to feel the performance through his or her body during performance.

[Conventional technology]

In a natural musical instrument, the generation of a musical sound vibrates the body of the musical instrument or the like, so that the player feels the vibration from his / her hands, fingers, mouths, etc.

For example, a player can feel the generation of a musical sound through a keyboard in a keyboard instrument, a mouthpiece or a key in a wind instrument, a body of a musical instrument in a stringed instrument, a neck or a string, and a membrane or repellency in a percussion instrument.

In addition, the vibrating action has a function of integrating the player and the musical instrument together with the playing sound to enhance the playing sensation.

[Problems to be solved by the device]

By the way, as an electronic musical instrument, an electronic wind instrument with a speaker and an electronic keyboard instrument with a speaker have been conventionally proposed. Although the sound emitted from the speaker is fed back to the player, they cannot receive the vibration feedback peculiar to the natural musical instrument generated by the performance. In particular, an electronic musical instrument has a structure in which an operating portion and a sound producing portion are separately provided by using an electronic circuit or the like as a sound source, unlike a natural musical instrument. The sound is produced by using a speaker or the like, and not the instrument itself. For this reason, the player feels the performance sound only by his / her ears, and the vibration feedback corresponding to the generated musical sound becomes insufficient, which may cause a sense of distance between the operation of the musical instrument and the performance sound.

So, this device receives the vibration effect according to the performance,
The purpose of the present invention is to provide an electronic wind instrument that enhances the feeling of performance through its vibration effect.

[Means for solving the problem]

That is, the invention is an electronic wind instrument having a pitch designating operator for designating a pitch of a musical tone signal to be generated and a mouthpiece, and a breathing pressure blown into the mouthpiece and a tonguing operation applied to the mouthpiece. And a tone control means for generating tone control data by detecting at least one of the two, and forming a tone signal having a characteristic corresponding to the tone control data, the tone pitch being designated by the tone pitch operator. A sound source and a vibration generating means for vibrating the electronic wind instrument by generating a vibration in accordance with the musical sound control data. [Operation] The musical sound controlling means is a breath pressure blown into a mouthpiece and a mouse. Tone control data is generated by detecting at least one of the togging operations applied to the piece. Then, the sound source forms a musical tone signal having a pitch designated by the pitch designating operator and having characteristics corresponding to the musical tone control data. Further, the vibration generating means vibrates the electronic wind instrument by generating vibration according to the musical sound control data.

By doing so, the player receives vibrations according to the performance and can get a real feeling of the performance, and the expressiveness is further enhanced.
