電子裝置的體積日益輕薄短小，且具有愈來愈強大的資料處理及通訊能力。因此，各類型的電子裝置應用在人們的日常生活中，也成為人們的日常生活中成為不可或缺的一部份。Electronic devices are increasingly thin and light, and have increasingly powerful data processing and communication capabilities. Therefore, various types of electronic devices are used in people's daily lives, and they have become an indispensable part of people's daily lives.

近年來，電子裝置，例如是電腦主機、平板電腦、顯示器、鍵盤、電視盒、與手機等裝置，功能日趨龐大，且也有將不同功能相互結合的設計及應用。為達到電子裝置彼此之間的通訊需求，以達到相互溝通，甚致於擴充電子裝置功能的目的，無線通訊也逐漸成為電子裝置的標準配備。In recent years, electronic devices, such as computer mainframes, tablet computers, displays, keyboards, television boxes, and mobile phones, have become increasingly popular, and there are also designs and applications that combine different functions.
