Mobile communication terminal equipped with bell tone changing function and operation method thereof

Abstract

The present invention discloses a mobile communication terminal setting the function of ring altering and the mode of operation, the mobile communication terminal comprises a microphone, a frequency analysis part used for analyzing the frequency characteristic of the noise data input from the microphone, a controlling part used for comparing the analyzed noise data and the frequency characteristic of the ring, and altering the frequency characteristic of the ring, and a frequency translation used for altering the frequency characteristic of the output ring according to the setting of the controlling part. According to the present invention, in the condition of having detected the incoming telegram, collecting the circumambient sound and altering the frequency characteristic of the output ring according to the frequency characteristic of the sound, the user increases the ring recognition rate when receiving the incoming telegram, thereby reducing the condition of the missed call and increasing the speaking success rate, and hereby increasing the credibility to the product and the convenience when in use.

Description

technical field [0001] The present invention relates to a mobile communication terminal and its operating method for identifying surrounding noises and changing ringtones, in particular to a mobile communication terminal provided with a ringtone changing function and its operating method. Background technique [0002] Generally, the frequency of audible sound that can be heard by humans is 20 to 20 khz, and the generally used frequency band is about 500 to 4000 Hz, but it may be easy or difficult to hear the sound of a specific frequency band depending on the hearing of each user. [0003] In particular, in a special environment such as a factory where noise above a certain level is continuously generated, sounds in a specific frequency band may not be heard due to surrounding noise. [0004] When a mobile communication terminal receives an incoming call, it outputs the set ring tone and prompts the user for the incoming call status. However, in noisy environments, especiall...

AI Technical Summary

Problems solved by technology

[0004] When a mobile communication terminal receives an incoming call, it outputs the set ring tone and prompts the user for the incoming call status. However, in noisy environments, especially in factories, markets, subways, bus stations, roadsides, etc., users often cannot hear the ringtone. The ring tone corresponding to the incoming call state of the above-mentioned mobile communication terminal

At this time, even if the output sound of the above-mentioned mobile communication terminal is set to the maximum, the user will be difficult to hear the output ring tone due to the surrounding environment.

[0005] Thus, when there is an environment with more noise around or a user working in the above-mentioned environment, the ring tone recognition rate corresponding to the incoming call state is greatly reduced due to the surrounding noise or noise interference, and the call cannot be made.
