摘　　要：针对目前学习机屏幕小,功能内容单一,智能化不强,单声道发音,个人单用等特点,提出一种带视频输出的学习机,使用了全新的设计理念,图文并茂,声音丰富,智能程度高,将学习机里的内容通过外接电视机或投影设备显示出来,通过大屏幕显示可让多人互动学习。省去了自带显示屏的成本和避免了屏幕显示太小的问题。Aiming at the characteristics of learning machine, such as the small screen, single function content, poor intelligence, mono pronunciation, using alone, etc, a kind of learning machine with a video output is proposed. A new design concept is used on the learning machine with the aid of diagrams, rich sound and advanced intelligence. Especially, the contents of the learning machine can be displayed through external TV or projector equipment, which allows muhiplayer interactive learning via large screen display, eliminates the costs of its own display, avoid the problem that the screen display is too small.
