Abstract

The invention discloses a compatible European standard and national standard earphone. According to the compatible European standard and national standard earphone, an automatic conversion circuit is employed, an input interface is made to realize reversal connection, and no influence is exerted on output signals. A problem of hardware incompatibility during reversal of order of microphones and ground wires of mobile terminal earphone interfaces in two standards can be solved, in a solution process, no wire jumping or setting is needed, no influence is exerted on circuit signal quality, and cost is low. Through the compatible European standard and national standard earphone, an intelligent compatible device having two standard interfaces can be realized.

Description

technical field [0001] The invention relates to an earphone compatible with the European standard and the national standard, in particular to an earphone compatible with the European standard and the national standard, and belongs to the field of earphones compatible with the European standard and the national standard. Background technique [0002] At present, there are two interface standards for earphone jacks with the same structure and size in terminal equipment such as computers, mobile phones, MP3, MP4, and PSP, while corresponding earphones can only support one interface standard at the same time. On the microphone signal, there will be a problem that the earphone cannot be used normally, which makes the earphone not universal. The 3.5mm four-segment earphones used in daily life are divided into two standards: European standard (OMTP): OMTP earphone is a standard for earphones with microphones formulated by the Open Mobile Terminal Platform Organization (OMTP) in ord...
