Description

Mobile phone which can generate melody according to keypad operation}

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.

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.

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.

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).

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.

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.

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.

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.

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).

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.

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.

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.

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.

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.

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.

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.
