Mobile phone which can generate melody according to keypad operation}
[10] The present invention relates to a mobile phone, and more particularly, to a mobile phone having a melody playing function in which a melody chip is embedded so that a user can play a melody by operating a keypad.
[11] Recently, due to technological advances in mobile phones and competitive low-cost policies on service costs, handset manufacturers that manufacture handsets that physically provide these services have become available as each carrier has an extensive subscriber base. It is launching various product lines to secure competitiveness of its handsets.
[12] Such wireless communication terminals are essentially provided with an incoming call alert system for notifying the initial connection of the communication. The general incoming alarm system includes an alarm sound method, a vibration alarm method and a lamp alarm method, and a general incoming alarm system is generally recognized as an alarm sound method. The vibration alarm method and the lamp alarm method use an alarm sound method. It can be used as a means of assisting.
[13] Recently, the incoming call alert system using the alarm sound method stores a number of alarm sounds ranging from a ring tone composed of a simple frequency combination to a complex melody in a storage medium, and gives a user the option to variably set it. Consideration is given to selecting the appropriate incoming alarm (ie incoming call).
[14] However, the number of incoming alarm sounds reserved on the storage medium of the terminal is inevitably limited due to the limitation of the storage space, and is fully inputted during the manufacturing process irrespective of the purchaser's preference. There is an inconvenience that cannot be done.
[15] In addition, recently, when the spread of wireless terminals has become common, when a ringing tone sounds in a crowded place, a lot of similar ringing sounds will be mistaken by another person as a ringing tone. There is some inconvenience in that the identification of the incoming alarm sound is unclear, such as checking the state or conversely mistaken the incoming alarm sound of another person.
[16] There is a known technique that can be eliminated by such inconvenience and can be used as an incoming alarm sound by keying the desired melody through the keypad according to the user's preference.
[17] Representative prior applications related to the music input method using the electronic telephone keypad as described in Korean Patent Application Publication No. 97-68399, "Phone including an electronic converter and a method of applying the frequency response of the converter and coding melody How to "and Korean Patent Application Publication No. 94-011753," telephones for generating a telephone ring melody assigned to a specific person "and the like.
[18] In addition, a product that can be used as an incoming call alert by key input through an electronic telephone keypad has been released. For example, a mobile phone, which has been released since the end of 1997, is equipped with a function of using a keypad to directly input a desired music score as a substitute for a reception bell (that is, a ringing tone). In other words, you can use the keypad to select the pitch for the sound and then select the pitch for the selected pitch. You can do this at any time by composing a new melody to change the incoming bell (i.e. the incoming melody).
[19] The music input method using the keypad is not only when you want to use the desired melody as an incoming alarm sound by keying the desired melody through the electronic telephone keypad, but also like a text transmission service, instead of using a commercial text message to send and receive a special music message. When you want to know the identity of the sender on the receiver's mobile phone through the unique melody coded by the receiver, or when you receive a call, or by using a melody-added value business-melody cards, doorbells, alarm clocks, children's toys, etc. When you want to provide a service that connects the melody input to the telephone business and converts it into various formats, it can be used.
[20] In this application field, the music input system is rich enough to express the score elements of each sheet music to be delivered, and when the user directly realizes such scores, the key button operation is simple and each sheet music The higher the degree of convenience of comprehensive operation, such as the easier to understand the layout of the presentation elements, is evaluated as the more desirable system.
[21] However, the music input method using the keypad according to the prior art has a limited octave reproduction ability, cannot use functions such as chords, and does not fully support various musical symbols that can represent standard sheet music. There is a lack of expressive ability to key in the music information, and this inconvenience is becoming a key factor to prevent the low change of the music input method using the keypad.
[22] In particular, in the case of the product which was produced and sold in 1997, the transliteration range between the base degree and the high beauty (that is, the basic degree, the basic beauty, the basic wave, the basic sole, the basic la, the basic time, the high degree, the high level, and the high beauty) As it supports only the music message beyond this has the most basic limitation that can not be input, as described above, after selecting the pitch, there is an inconvenience to select a pitch length for this pitch separately.
[23] In addition, although other mobile carriers provide the service of "my own ringtone" through the Internet, this is an additional inconvenience, such as the use of a medium other than a telephone must be connected to the Internet to receive such services.
[24] Accordingly, an object of the present invention is to provide a mobile phone having a melody playing function capable of playing a melody by incorporating a melody chip to solve the above problems.
[25] In addition, an object of the present invention is to provide a mobile phone with a melody playing function that can be used as a ring tone by recording the melody by playing the melody built-in melody chip as a ring tone.

[27] Now, with reference to the drawings of Figure 1 will be described in detail a preferred embodiment of the present invention.
[28] 1 is an exemplary view showing a keypad used in the present invention.
[29] In general, an electronic telephone keypad consists of a four-row, three-column key button array, which is "1", "2", "3", "4", "5", "in order from left to right, and from top to bottom. 6, 7, 8, 9, *, 0, and ## key buttons are assigned. Push each key button to Halftone "," les "," halftone "," mi "," wave "," halftone "," sol "," halftone "," la "," halftone "," hour ".
[30] In this case, when the user presses two or more keys at the same time, each frequency may be implemented together.
[31] When the melody is played, mapping the keypad to the scale like this makes it possible to play all the notes.
[32] Figure 2 is an internal block diagram of a mobile phone with a melody playing function according to an embodiment of the present invention.
[33] The key input unit 20 includes a plurality of keys for generating a dial key signal and a character automatic transmission function selection key, and inputs the CPU 10 to the CPU 10 when the key data is generated.
[34] The CPU 10 controls the operation of the terminal, recognizes the key pressed from the key input unit 20, generates a melody selection control signal for distinguishing the key signal, and outputs it to the melody chip 90.
[35] The display unit 30 displays the dial telephone number and each region under the control of the CPU 10. The memory 40 stores mapping information for each corresponding musical scale with respect to the key of the key input unit 20 for playing the melody.
[36] The duplexer 60 communicates with the base station through the antenna AT so that the signal from the transmitter 80 is transmitted to the base station through the antenna, and the signal from the base station through the antenna is received by the receiver 70. .
[37] The receiver 70 is controlled by the controller 10 and receives a radio signal output from the duplexer 60.
[38] The transmitter 80 transmits the modulated radio signal from the audio unit 50 to the duplexer 60. The audio unit 50 is controlled by the control unit 10, modulates the voice signal input through the microphone (MIC) into a wireless signal, and demodulates the wireless signal received through the receiver 70 to the speaker (SP) The audio signal is sent to the camera.
[39] In addition, the audio unit 50 detects the ring signal through the receiver 70 when the ring signal is generated from the base station and transmits the ring signal through the ringer. Accordingly, the user acoustically confirms that a ring signal is generated from the base station.
[40] The melody chip 90 generates various melody frequencies by the melody selection control signal of the CPU 10.
[41] The filtering unit 100 filters the melody frequency, converts the melody frequency into a tone, and outputs the tone to the amplifier 110. The amplifier 110 amplifies the melody tone to a predetermined level and transmits the same through the speaker.
[42] Here, the melody chip 90 has a command (degree, semitone, ré, semitone, me, wave, and the like) under the control of the CPU 10 when the numeric keys of the key input unit 20 are sequentially pressed from 0 to 9 or * key or # key. Semitones, sols, las, semitones, poetry) should produce a piano or other musical instrument that produces a higher pitch.
[43] Next, with reference to Figure 3 will be described in detail the operation of the preferred embodiment of the present invention.
[44] The user first selects the melody playing function by operating the terminal (S100). Then, the terminal outputs a screen for selecting which musical instrument to play the melody, and the user selects a desired musical instrument therefrom (S110). It is also possible to omit step S110 and to play with the sound of the musical instrument set as a default.
[45] When the instrument is selected in this way, until the user cancels this function, if the user presses the keypad, the sound of the selected instrument is output by the scale assigned to the corresponding key button (S120).
[46] The key input unit 20 includes * keys and # keys used as numeric keys (0-9) and function keys for dialing a telephone number. When the user presses the corresponding key, the CPU 10 enters the key input unit 10. Recognizing a key pressed from the) generates a melody selection control signal for distinguishing the key signal and outputs it to the melody chip (90).
[47] The melody chip 90 generates various melody frequencies by the melody selection control signal of the CPU 10.
[48] When the frequency for the instrument sound is generated from the melody chip 90, the filtering unit 100 filters the instrument sound frequency and converts it to have a tone and outputs it to the amplifier 110. The amplifier 110 amplifies the melody tone to a predetermined level and transmits the same through the speaker.
[49] On the other hand, although only the music performance is described here, it can be recorded and used as a ring tone.
[50] Based on the music input method of the present invention described above, a song such as "Deep Mountain-Genus-Ong-Dal-Sam-Who do you eat " When keyed in, it can be represented as:
[51] |: Misol Domisole--Pa--La--La--Solsirepamiredo ---------: |
[52] Deep Mountain- Inner--Ong--Dal--Sam--Who Come and Eat ---------
[53] 5 8 1 5 8 --- 6 --- * --- * --- 8 # 3 6 5 3 1 ----------
