Electronic organ

Abstract

The invention provides an electronic organ which comprises a sounding device, a keyboard, a plurality of keys and switching circuits, wherein the plurality of keys are arranged on the keyboard, and the switching circuits correspond to the keys in a one-to-one mode. The keys are connected with the sounding device through the switching circuits corresponding to the keys. When one key is pressed down, the switching circuit corresponding to the key is closed, and therefore the sounding device generates a musical tone. The right hand position of a player serves as the right side of the keyboard, the closer the key is to the right side, and the higher the musical scale of the musical tone corresponding to the key is. The keys are smaller and tinier than regular keys, so that a finger position can press at least two adjacent keys. Except for the key closest to the right side, the switching circuit corresponding to any key is relevant to the adjacent key on the right side. Particularly, when the adjacent key on the right side is pressed down, the switching circuit corresponding to the key is in an opened state. The electronic organ has the advantages of being simple, reasonable, convenient to play, multiple and dense in musical scale and fine and smooth in musical style.

Description

technical field [0001] The solution of the invention relates to an electronic organ. Background technique [0002] The electronic organ has a long history as a musical instrument in music performance. Its main principle is that the key presses the key through a one-to-one corresponding switch circuit to the sounding device, and the sounding device emits a tone corresponding to the pressed key. , the pronunciation device has evolved continuously from the appearance of the electronic organ to the present, and various technical solutions have emerged, such as using PCM or AWM to sample the sound source. The CPU plays back the sound, and the switch circuit of the electronic organ using the sounding device is mainly used to input the position information of the pressed key to the CPU; The circuit is mainly used to activate the electrical device corresponding to the pressed key, but no matter which method is used, the key of the electronic piano is essentially a button switch, th...

[0002] The electronic piano has a long history as a musical instrument in music performance. Its main principle is that the key presses the key through a one-to-one corresponding switch circuit to the sounding device, and the sounding device emits a tone corresponding to the pressed key. , the pronunciation device has evolved continuously from the appearance of the electronic organ to the present, and various technical solutions have emerged, such as using PCM or AWM to sample the sound source. The CPU plays back the sound, and the switch circuit of the electronic organ using the pronunciation device is mainly used to input the position information of the pressed key to the CPU; The circuit is mainly used to activate the electrical device corresponding to the pressed key, but no matter which method is used, the key of the electronic piano is essentially a button switch, that is, each key is equipped with a corresponding switch circuit to control the pressing action of the key. Pass to pronunciation device, but there is a common limitation in these prior art: because the key is thicker than finger position and the key corresponds to the scale one by one, the keyboard must be continuously lengthened when adding the scale on the keyboard, but the player's both hands take into account the range limited, so that the scale setting of the keyboard cannot be too dense
