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:
The electronic installation that is to use earphone involved in the present invention, as sound equipment, mobile phone (cellular phone), visual telephone, singing device, game device, plain old telephone and network (the Internet) phone, particularly utilize the indoor large sound equipment or portable sound equipment (magnetic tape type) device of earphone and wireless headset.
Background technology:
Generally, if we want to listen to the electronic installation that uses earphone, as the sound that large and small type sound equipment (recorder) sends, we need insert the earphone cord plug in the jack of acoustics so that the two links to each other.But for large-scale room sounding, if the position is far away, we just need earphone cord to have enough length to connect sound equipment, can in processing, produce inconvenience like this, even for portable sound equipment, in order to listen to sound, earphone cord also needs to link to each other with sound equipment constantly.
Summary of the invention:
The present invention is used for improving the conventional earphone of utilizing electric wire to link to each other with electronic installation.In addition, the present invention can make those use the electronic installation of wired earphone can utilize wireless headset to listen to sound, and has invented the wireless headset that is suitable for these electronic installations, and like this, the sound that electronic installation sends just can be listened to by wireless headset and obtain.
Electronic installation that is to use earphone and wireless headset involved in the present invention, it is characterized in that: utilize plug or usual manner that traditional small-sized stereo reflector of no antenna is installed in the electronic installation that uses earphone, and in small-sized traditional receiver, trimmer capacitor is installed for adjustable condenser, for variable resistance is installed coupling resistance.
After above-mentioned electronic installation has been installed, utilize wireless headset can receive sound from sound equipment.Like this, even away from sound equipment, no matter be indoor or outdoor, we can both utilize wireless headset to receive sound from sound equipment.
Description of drawings:
Fig. 1 is the circuit diagram that is applied to the reflector among the present invention.
Fig. 2 is the circuit diagram that is applied to the receiver among the present invention.
Embodiment:
By accompanying drawing as can be known, the present invention mainly comprises and utilizes plug 3 or usual manner that the small-sized stereo reflector T of traditional no antenna is installed in using the electronic installation of earphone and be trimmer capacitor 1 that adjustable condenser is installed and be the coupling resistance 2 of variable resistance installation in small-sized traditional receiver R.
Claims (1)
1, a kind of electronic installation that uses earphone and wireless headset, it is characterized in that: utilize plug or usual manner that traditional small-sized stereo reflector of no antenna is installed in the electronic installation that uses earphone, and in small-sized traditional receiver, trimmer capacitor is installed for adjustable condenser, for variable resistance is installed coupling resistance.
