Abstract

The invention relates to the combined application of the technical field of wired communication and the technical field of mobile communication, and particularly relates to a system for realizing voice calling through connecting a common landline phone with a mobile phone. The system for realizing voice calling through connecting the common landline phone with the intelligent mobile phone comprises one common landline phone, one common intelligent mobile phone, one USB data line and a switching system of the common landline phone and the intelligent mobile phone. In the switching system of the common landline phone and the intelligent mobile phone, a telephone set interface circuit is formed by user interface chips. A processor of a common embedded type system is also used as a core control chip which is connected with the intelligent mobile phone via a USBHOST interface of the core control chip. A standard I2S audio interface and an I2C interface are used between the core control chip and the user interface chips. Radiation of the mobile phone can be kept away, and voice calling called in or called out by the mobile phone is switched via utilizing the landline phone so that radiation hazards to a human body by the mobile phone are avoided.

Description

technical field [0001] The invention relates to the combined application of the technical field of wired communication and the technical field of mobile communication, in particular to a system for connecting a common telephone landline to a mobile phone to realize a call. Background technique [0002] In the past 20 years, with the development of mobile communication technology, people can use portable mobile terminals to realize voice calls anytime and anywhere. At the same time, the harm to human body caused by electromagnetic radiation generated by mobile terminal antennas sending and receiving radio frequency signals has become a problem that cannot be ignored. . [0003] In order to reduce the damage caused by radiation to the human body, the usual practice is: first, add a shielding cover made of metal on the upper and lower sides of the mainboard of the mobile phone, and then install a shell on the outside of the metal shielding cover; The high-performance materials...
