TELEPHONE HANDSET AND METHOD FOR DYNAMICALLY BUFFERING REAL-TIME SOUND SIGNAL

摘要

PROBLEM TO BE SOLVED: To provide a telephone handset and a method for dynamically buffering a real-time sound signal. SOLUTION: This telephone handset is provided with a microphone and a speaker connected to a telephone network system. A proximity sensor is located near the speaker of the telephone handset. This proximity sensor is connected to a circuit for measuring the coupling between the telephone handset and the ear of a user. A buffer continuously records real-time sound signals. Thus, after the telephone handset is first decoupled from the ear of the user and next coupled with the ear of the user again, the recorded signals can be reproduced by using time-compressed sound signals. Such reproducing is continued until a reproduced signal is synchronized with the real-time sound signal again.
