摘要： PROBLEM TO BE SOLVED: To solve the problem in the detection of an earphone connection to a terminal unit that noise generated by an electrical connection when earphones are inserted into the terminal unit poses inconvenience to the user, and that although a conventional earphone connection detection process relied on the use of ground terminals installed in the earphones to check a change of states in electrical connection, a state of earphones inserted into place cannot always be detected correctly when shorting or other trouble occurs in the earphones.SOLUTION: Regarding the detection of an earphone connection to a terminal unit, the present invention discloses the composition of an earphone connection detection system in which a physical change due to an earphone connection is detected especially as an electrical change by making use of a switching device which is electrically insulated from the earphones, thereby providing a support for making it possible to detect an earphone connection.
摘要翻译：要解决的问题为了解决在将耳机插入终端单元时，检测到终端单元的耳机连接的问题，电话连接产生的噪声对用户造成不便，并且尽管传统的耳机连接检测过程依赖于使用安装在耳机中的接地端子来检查电气连接状态的变化，当在耳机中发生短路或其他故障时，插入到位的耳机的状态不能被正确地检测到。解决方案：关于对终端单元的耳机连接的检测，本发明公开了一种耳机连接检测系统的组成，其中由于耳机连接而引起的物理变化特别是通过利用与耳机电绝缘的开关装置，从而提供支持以使其能够检测耳机连接。版权所有（C）2013，JPO＆INPIT
