Abstract

In electronic device using earphones a conventional stereo transmitter using without antenna is connected and in a receiver capable of receiving without an antenna a small trimmer for a variable condenser and a coupled resistances for a variable resistor are connected to receive sound from electronic device by a wireless earphone.

Description

Technical field: [0001] The present invention relates to electronic devices using earphones, such as stereos, mobile phones (cellular phones), video phones, singing devices, game devices, ordinary phones and network (Internet) phones, especially indoor large-scale electronic devices using earphones and wireless earphones. Audio or portable audio (cassette) devices. Background technique: [0002] Usually, if we want to listen to the electronic device that uses earphone, as the sound that big and small stereo (tape recorder) sends, we need to insert the plug of earphone cable in the jack of audio device so that the two are connected. But for large indoor speakers, if the location is far away, we need the headphone cable to have enough length to connect to the speaker, which will cause a lot of inconvenience in processing, even for portable speakers, in order to listen to the sound, the headphone cable also needs to be connected. Always connected to the sound. Invention cont...
