Description

Octave expansion method for music performance using a mobile terminal {OCTAVE EXPANSION METHOD FOR MUSIC PLAYING USING MOBILE TERMINAL}

The present invention relates to an octave expansion method of music performance using a mobile terminal, and in particular, when a user wants to play music by directly pressing a keypad using a sound source chip built in the mobile terminal, at least three key combinations using side keys are performed. The present invention relates to an octave extension method of music performance using a portable terminal that enables natural performance in a octave range.

Along with the rapid expansion of the functions of portable terminals, the fastest changing parts are the screen output part and the ring output part. Among these, the ring part has been improved to support the use of multiple chords and various sources beyond the existing single tone output, and recently, the ringtone of 40 chords is also supported.

In other words, in the current portable terminal, a midi chip having various sound sources is basically applied and used to play a midi file created for a ringtone.

Therefore, it can be used as a digital keyboard that reproduces a user's key input by using a built-in MIDI chip, but due to the limited number of keypads, the range that can be played is only one octave.

Similarly, early mobile terminals had the ability to create music by themselves and use the music as a ringtone. However, in the early mobile terminals, single notes were used, and the method of writing scores was also impossible because it used a method of selecting a note and writing it to an appropriate position. In order to create a simple melody, a great effort was required, so it was briefly applied to an early mobile terminal, and the function is not used because the mobile terminal is currently used.

1 illustrates an arrangement of a keypad 10 of a typical mobile terminal. As shown in the drawing, means for accepting a user's input includes function keys 11 for selecting various functions and numeric keys for receiving numbers and letters. (12), and first and second side keys 13 and 14 are arranged for menu direction and volume operation.

As shown, there are only 12 basic numeric keys 12, so this is the number of notes of one octave including semitones (A, A #, B, C, C #, D, D #, E, F, F #, G, G #). Matches 12). In other words, if all the numeric keys correspond to the scale, only one octave can be used. Therefore, when playing music using this, only very limited music can be played.

Since general music usually has a range of two to three octaves, it is impossible to play music smoothly using the numeric keys alone.

As described above, the conventional portable terminal has a MIDI chip in which various sound sources are embedded, but only the data which has been created can be received, stored, and played back, and the limited number of keypads can not be used to directly play the keypad. In addition, since the composition function applied to the early portable terminal is not possible to play directly, since a predetermined score is written one by one through a plurality of key inputs, it is possible to play it.

In view of the above limitations, the present invention corresponds to a scale of one octave to keys on a keypad of a mobile terminal, and assigns an octave by using a side key to determine an octave with a hand supporting the mobile terminal and to a keypad with a free hand. It is an object of the present invention to provide an octave extension method of music performance using a portable terminal that allows the user to freely play in at least three octave ranges by pressing an assigned sound.

The present invention for achieving the above object, the step of assigning a scale of one octave to the keypad numeric keys of the mobile terminal; Allocating side keys of the portable terminal for octave selection; And selecting the sound assigned to the keypad of the mobile terminal by pressing the side keys one by one or in combination or by pressing the side keys so that the corresponding sound is output in a preset octave.

The octave used further comprises the step of selecting a range of at least three octaves or more by setting a predetermined octave for each of a state in which side keys are not pressed and one or a combination of side keys are pressed. .

The method may further include selecting a sound source to be played through a menu operation of the portable terminal or selecting a function key to play with various musical instruments.

The method of the present invention as described above will be described in detail with reference to the accompanying drawings.

FIG. 2 illustrates a scale arranged according to an embodiment of the present invention. As shown in FIG. 2, the numeric keys 12 correspond to the scale of one octave. In other words, place the 1st key as "A" for "La" note, and the 2nd key as "A #" for "La #". It arrange | positioned corresponding to "*", "0", and "#" in order. Of course, this arrangement is familiar to users who have learned instruments, including keyboard instruments, and more commonly, assigning them to the first key and placing the "trial" to the "#" key. It may be.

At least two of the general side keys may designate an upper octave as the first side key 13 and a lower octave as the second side key 14. That is, when the side keys 13 and 14 are not selected, a sound of a key input is generated as a reference octave, and when a key input is held while the first side key 13 is pressed, the sound of the corresponding key is increased by one octave. If there is a key input while pressing the second side key 14, the sound of the corresponding key is generated one octave lower.

FIG. 3 shows a case in which a "degree" sound is selected by using an intermediate octave. As shown in the drawing, when the "C" sound assigned to the "4" key is pressed without pressing the side keys 13 and 14. to be. If you look at the notes in the dotted line, you will see that the "degree" sound is one octave higher than the normal "warm temperature" as the default octave.

In general, the output speaker of the mobile terminal is small in size, it does not provide enough sound quality at low. In other words, the octave as a reference is set one octave higher than the normal reference octave because the sound is clear at high frequencies. This is natural to those skilled in the art of designing audio-related functions, but it is noted that the present invention is not limited to the setting of this reference octave, and may be set to an optimal octave according to the speaker type of the portable terminal.

FIG. 4 illustrates a case where a low octave “degree” sound is selected in the embodiment of the present invention. As shown in FIG. 4, the second side key 14 located at the lower side of the side keys is pressed and assigned to the “4” key. Is when the "C" note is pressed. Looking at the note in the dotted line, it can be seen that it represents a general 'warmity' and generates one octave lower than the basic octave shown in FIG.

5 is similar to FIG. 4, by pressing the "C" tone assigned to the "4" key while pressing the first side key 13 located at the top of the side keys, one octave higher than the reference octave of FIG. Generates.

Through the illustrated embodiment of the present invention, the user can easily perform the performance over the range of three octaves. In general, since the mobile terminal is supported by one hand for key operation of the mobile terminal, and the other hand presses the keypad of the mobile terminal, the keypad of the mobile terminal is operated by pressing the side keys 13 and 14 with the supporting hand. You can play the music you want.

Although the present invention has described the case of three octaves, it is possible to add higher or lower octaves by simultaneously pressing the side keys 13 and 14, and in the case of applying three or more side keys, It is also worth noting that by combining, you can set up a very wide range.

In addition, commercially available mobile terminals are equipped with a midi chip embedded with a variety of sound sources, so that the user can select the desired instrument sound through the menu or function keys (11) before playing, the function keys (11) You can also change the sound of the instrument using) so that you can use your mobile device as a simple keyboard.

As described above, if you expand the range enough to play most melodies using a mobile terminal and select various musical instruments using the built-in sound source, a simple digital piano or keyboard level performance can be performed. Therefore, it is a very attractive feature for users with strong personalities because it is not just a passive acceptance of music written by others, but also an instrument that can be played by oneself.

As described above, the octave expansion method for music performance using the mobile terminal corresponds to an octave scale on the keypad of the mobile terminal and assigns an octave using the side keys. By setting the octave and pressing the keypad with the other hand to output the selected octave note, the built-in sound source can provide free performance in at least three octave ranges, so that the portable terminal can be used as a digital instrument.
