Embodiment 1

[0027] Such as figure 1 , to display the keyboard interface on the capacitive multi-touch screen. The electronic keyboard interface includes 12 key areas, and these 12 key areas form a sound group, of which 7 are white key areas and 5 are black key areas. The appearance and size of the 12 key areas refer to the real electronic keyboard settings. From left to right, there are three key areas of white keys sandwiching two key areas of black keys, and four key areas of white keys sandwiching three key areas of black keys.

[0028] The tones corresponding to the three white key areas on the left are C tone, D tone and E tone in turn; the tones corresponding to the four white key areas on the right are F tone, G tone, A tone and B tone in turn. The clavichord key areas are semitones respectively adjacent to the adjacent white key key areas.

[0029] A note display area is provided above the 12 key areas, and symbols such as staves, musical notes, diacritical marks, key signatures...

Embodiment 2

[0032] A method for realizing a touch-type virtual electronic organ, comprising the following steps:

[0033] Confirm that a touch object touches the touchscreen, and

[0034] Detecting the position coordinates (Xn, Yn) of the touch object;

[0035] If the position coordinates (Xn, Yn) fall into the key area, activate the key area, and

[0036] Detect the touch pressure Pn of the touch object on the key area;

[0037] Adjust the volume and pitch according to the touch pressure Pn and emit the sound of the note corresponding to the key area through the speaker;

[0038] At the same time, the activated key area is pressed by the touch screen, and

[0039] The note corresponding to the activated key area is displayed in the note display area;

[0040] Record the tone corresponding to the activated key area, and automatically compose music through the software.

Embodiment 3

[0042] combine figure 2 , a method for realizing a touch-type virtual keyboard, comprising the following steps:

[0043] confirming that two or more touch objects touch the touchscreen, and

[0044] Detect the position coordinates of each touch object;

[0045] If each position coordinate falls into a different key area, activate each key area, and

[0046] Detect the touch pressure of each touch object on the keyboard area;

[0047] According to each touch pressure, the volume and pitch are adjusted respectively, and the sound of notes corresponding to each key area is emitted through the loudspeaker.

[0048] At the same time, the touch screen displays the action that the activated key area is pressed;

[0049] The note corresponding to the activated key area is displayed in the note display area;

[0050] Record the tones corresponding to each activated key area, and automatically compose music through the software.

[0051] The touch screen in the foregoing embodime...

Abstract

The invention discloses a realization method of a touch electron piano. The realization method is characterized in that the method comprises the following steps: presetting at least an electronic organ interface comprising a plurality of keyboard areas which correspond to the tones of different notes and note display areas on a touch screen; confirming that N touch objects touch the touch screen and detecting the position coordinates of N touch objects; activating N keyboard areas and detecting the touch pressures of N touch areas to N keyboard areas when the position coordinates respectively arranged in the keyboard areas; and adjusting volume and / or tone according to N touch pressures and producing the sounds of N tones corresponding to the keyboard areas. The realization method of the touch electron piano provided by the invention adopts a touch screen, realizes electronic organ interface through software, and can stimulate the playing of an electronic organ and realize the pitches of volume and / or tone according to the touch pressure.

Description

technical field [0001] The invention relates to the application field of touch screens, in particular to a method for realizing a touch-type virtual electronic organ. Background technique [0002] Touch screens, especially capacitive touch screens that can realize multi-touch, have been recognized by the society and have begun to be popularized on electronic devices such as personal digital processing (PDA), mobile phones, handheld computers, and tablet computers. Currently, most of the existing virtual keyboards use keyboards, mice or specific sensors to simulate keys, and display corresponding keyboard interfaces through TV screens or computer monitors. This type of method is costly and requires additional equipment, and its large size is not conducive to movement and use. Contents of the invention [0003] The purpose of the present invention is to overcome the defects of the above-mentioned virtual electronic organ, and realize the virtual electronic organ by using a ...
