METHODS AND DEVICES FOR ADAPTIVE RINGTONE GENERATION |
摘要 |
<p>Disclosed are methods and devices for adapting a ringtone in accordance with ambient noise. In one embodiment a method includes processing an ambient noise signal to determine an ambient noise volume. When there is an incoming communication and it is determined that the ambient noise has a low ambient noise volume, a method can include generating a ringtone having a ringtone volume that is initially a low volume and increasing the ringtone volume over a predetermined period of time. A method can include applying a filter to the ringtone signal to increase a signal-to-noise ratio, the filter configured to increase an amplitude of a frequency that is not one of the predominant frequencies of the ambient noise and that the transducer is configured to output according to the transducer frequency response. In another embodiment, a second transducer may generate a ringtone output in addition to the first transducer.</p> |
