Abstract

PURPOSE:To realize a miniature and lightweight portable information unit low in frequency of replacing batteries, by using a semiconductor memory as a recording medium with an acoustic memory function. CONSTITUTION:A sound signal after passing through microphone 2 is amplified by amplifier 3, digitized by A/D converter 4 and stored in semiconductor memory 1, so that the recording operatioin will end. To regenerate the signal, data outputted from memory 1 are converted by D/A converter 5 into an analog signal, which is passed through amplifier 6, thereby driving speaker 7. The address of memory 1 is determined by address counter 8. Once addressing from keyboard 9 is performed, I/O port 10 allows display body 11 to display the address in addition to control such as recording, regeneration and retrieval. When memory 1 uses a semiconductor memory, no latency time is required and the miniaturization and the reduction in power consumption are both realized because of no need of fast-forward and rewind functions.
