Abstract： |
The invention relates to a bidirectional digital modulation multi-channel manual cochlear system, pertaining to the arts of electronic information technology and medical appliance. The system comprises external and internal circuits and electrodes. The external circuit is for collecting sound signal and sending to the internal circuit after enlarging, digitalizing and modulating in wireless way, at the same time, providing interface for programming and measuring the internal circuit. The internal circuit demodulates the received signal, and deals the demodulated data by the built-in digital signal-processing unit, to control the outlet of electrode assemblies, program on line or provide reversal results. The system integrates the low-power consumption digital signal-processing unit to the internal circuit, so the external circuit only sends narrow range sound signal, to cancel the width limitation of wireless transmission band, and improve the accuracy of dealing. Moreover, the system provides with remote updating. |
