Abstract

PURPOSE: To obtain an acoustic reproducer which features an easy and high-speed channel retrieving and is thus suited the conversation aid device by reproducing only the information of the designated specific channel among several acoustic information featuring a comparatively short length of the channel information.
CONSTITUTION: Address conversion circuit 2 converts the channel number designated by switch 1 into the address into which the channel information is stored in memory circuit 4. Reading control circuit 3 controls the reading to circuit 4 according to the output signals of circuit 2 in order to read out only the acoustic information corresponding to the channel designated by switch 1. The acoustic information read out of circuit 4 is applied to D/A converter 5, and converter 5 converts the applied digital code row into the analog electric signal. The output signal of converter 5 is applied when necessary to electric acoustic converter 7 such as the speaker via amplifier 6, thus reproducing the acoustic signals.
