Bell sound outputting apparatus and method thereof

摘要

A method and apparatus for outputting a bell sound are disclosed. The method includes receiving an ambient noise; extracting a target frequency band from the ambient noise; changing volume of a pre-stored bell sound by using the target frequency band; and outputting the changed pre-stored bell sound. In the apparatus for outputting a bell sound, when a bell sound outputting apparatus receives an incoming call signal, a user may hear a bell sound including a signal in a frequency band not existing in a peripheral environment, and thus may easily recognize the bell sound.

主权项

1. A bell sound outputting apparatus comprising:
an input unit which receives an ambient noise; an extracting unit which extracts a target frequency band from the ambient noise; a control unit which changes a volume of a pre-stored bell sound by using the target frequency band; and an output unit which outputs the changed pre-stored bell sound; wherein the control unit changes a magnitude of a signal of the pre-stored bell sound in a frequency band neighboring the target frequency band until a ratio between a changed magnitude of the signal in the target frequency band and a magnitude of the signal in the neighboring frequency band is equivalent to or approximately a ratio between a magnitude of the signal in the target frequency band and a magnitude of the signal in the neighboring frequency band calculated before the change.
