DIGITAL SOUND DATA STORING DEVICE

摘要

This invention relates to a digital sound data storing device in which analog signals are obtained from digital sound data. The digital sound data storing device includes a case enclosing a reproduction unit and an IC card detachably attached to the case. A plurality of digital sound data groups are stored at a built-in IC memory of the IC card. The sound data groups are obtained, for example, by recording short sentences for practicing conversation of a foreign language, through a microphone to obtain analog sound signals and digitizing the analog sound signals. When the IC card is attached to the case, a sound synthesis circuit enclosed in the case reads out the sound data groups and converts the digital sound data groups to analog signals, which are amplified to be reproduced as sound groups. When any one of push buttons disposed on the case is depressed to input an identification code corresponding to any sound desired or not desired to be reproduced, data of the identification code is inputted in the built-in memory. Based on the data of the identification code, the sound groups are selectively reproduced or selectively excluded from the sound groups to be reproduced.
