An actual training a device for a language study using wireless connestion type

摘要

The present invention relates to a language practice apparatus, and in particular, the AD conversion interface means for receiving the learning content or voice signal uttered by each lecturer and the school speaker is converted to digital data and outputted; Infrared transmitting means for converting an input signal into an infrared signal and wirelessly transmitting the infrared signal; Infrared receiving means for receiving an infrared signal transmitted wirelessly from the infrared transmitting means and converting it into an electrical signal; DA conversion interface means for converting the received data through the infrared receiving means is converted into an analog signal and delivered to the lecturer or each student; And converting the digitally converted data through the AD conversion interface means into a source signal of an infrared ray transmitting signal and providing the same to the infrared ray transmitting means, converting a signal received through the infrared ray receiving means into a digital signal and converting the DA. When providing a language training apparatus using a wireless access method characterized in that it comprises a transmission and reception data conversion means provided on the interface means side, 1: 1 installation, maintenance and maintenance, which is a disadvantage of the language training room system according to the existing wired communication method. It is possible to provide a low cost and efficient learning facility in response to the increase in cost.
