Description

Receiving tone generation apparatus for mobile phone

The present invention relates to a mobile phone, and more particularly, to an apparatus for generating a reception sound of a mobile phone.

In recent decades, wireless communication technology has developed a lot. With the development of communication technology, the spread of personal portable telephones is increasing. As the popularity of personal portable telephones increases, some problems arise in use. One of them is a problem in which crosstalk occurs between users due to the same or similar reception sound generated by various portable telephones.

The reception sound generated by most portable telephones uses the same kind of reception sound when manufactured by the same manufacturer, and similar reception sounds are used by products of different manufacturing circuits. Therefore, when wireless reception sounds are generated in crowded places of users of portable portable telephones, such as public places, users frequently repeat cumbersome operations to check whether they are received from their portable telephones. As a method for solving such a problem, the reception sound of the portable telephone is diversified, but the generated reception sounds basically use electronic sounds, and thus there is a problem in that the distinction between users is not large.

Accordingly, it is an object of the present invention to provide a reception sound generating device for a portable telephone, which has been proposed to solve the above-mentioned problems and generates reception sounds that can be easily distinguished between portable telephones.
