| 摘要 |
The present invention relates to a device for optical signaling an incoming call in a telecommunication terminal, said terminal comprising acoustic means for signaling the incoming call with an acoustic signal and said device comprising optical means (200A, 200B) for signaling said incoming call with an optical signal, said device being characterized in that the acoustic means are coupled to the optical means such that said optical signal is dependent on parameters of the acoustic signal. For example, the optical signal can depend on the frequency of the acoustic signal or on a chronological sequence of individual tones of the acoustic signal. ® KIPO & WIPO 2007
