Abstract
The utility model relates to a computer radio microphone earphone. The existing computer microphone earphone is bound by the conducting wire length, the functions of listening and teaching simultaneously can not be realized by the radio earphone either, and the operation and the usage are extremely inconvenient. The utility model provides a computer radio microphone earphone with synchronous listening and teaching, and the computer radio microphone earphone is not bound by the conducting wire and can act freely. The utility model is composed of a transmitting apparatus and a receiving apparatus, wherein, the transmitting apparatus comprises a shell, a transmitting circuit board, a power supply, an antenna and a signal plug. The panel of the shell is provided with an LCD, an adjusting key and a power supply indicating lamp, and the side face of the shell is provided with a power supply switch. The transmitting circuit board is arranged in the shell. The power supply is arranged at the rear part of the shell, and 3-12V can be adopted to supply power. The receiving apparatus is a headset radio microphone earphone, which comprises an earphone frame, an earphone, a microphone, a receiving circuit board and a power supply, and the power supply adopts 3.6V to supply power. The maximal receiving and transmitting distance is larger than 10 meters. The utility model has the advantages that the conducting wire is omitted, the listening and the teaching can be carried out synchronously, the utility model can be widely applied to the occasions of teaching, conference, etc., the conversation is free, and the operation is flexible and convenient.
