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 (1) for a variable condenser and a coupled resistances (2) for a variable resistor are connected to receive sound from electronic device by a wireless earphone.
Description
Electronic Devices using Earphones and Wireless
Earphones.
BACKGROUND OF THE INVENTION
FIELD OF THE INVENTION
The present invention relates to electronic devices using earphones such
as audios, hand phones(Cellular phones), video phones, device for singing,
game device, general telephones and internet phone and wireless
earphones, more particularly, to electronic devices using earphones such
as large audios for the rooms or portable small audios(cassettes) and
wireless earphones.
DESCRIPTION OF THE PRIOR ART
Generally in earphones for electronic devices using earphones such as
large audios or small audios i.e cassettes wires having earphone plugs for
connection with jack of the devices should be connected in order to hear
sound from electronic devices.
Therefore m case of large audios for the room since the electric wire
should be long in order to connect with the devices placed far away
there is very incovenient to handle them and also in case for portable
cassettes as small audios cassectes should be always connected by wire
with earphones in order to hear sound from the cassettes.
SUMMARY OF THE INVENTION
The present invention is to improve conventional earphones having
electric wires for electronic devices. Furthermore the present invention is
to provide electronic devices using earphones capable of hearing sound of
electronic devices by wireless earphones and wireless earphones for the
devices, so that sound of the electronic devices can be heared from the
electronic devices by only earphones without wires.
DESERPTION OF THE DRAWINGS
.Fig 1 represents an example of circuits of transmitters being used in the
present invention.
Fig 2 represents an example of circuits fo receivers being used in the
present invention.
DETAILED DESCRIPTION OF THE INVENTION
Now referring to the accompanying drawings the present invention is
described in detail as below.
The present invention relates to electronic devices using earphones and
wireles earphones characterized in installing, by plugs 3 or by
conventional means, conventional small stereo transmitters T without
antennas having circuit as shown in Fig 1 in electronic devices using
earphones and in installing small trimmers 1 for variable condensers and
coupled resistances 2 for variable resistor in conventional small receivers
R of earphones capable of receiving without antennas having circuits as
shown in Fig 2.
Upon the above-stated electronic devices using earphones and wireless
earphones sound transmitting from the electronic devices can be heared
by earphones without wires.
Accordingly although the electronic devices are placed far away from
earphones each other indoors or outdoors sound from the electronic
devices can be heared by wireless earphones clearly.
Claims
1. Electronic devices using earphones and wireless earphones
characterized in installing, by plugs 3 or conventional means, conventional
small stereos transmitters T without antennas in electronic devices using
earphones and in installing small trimmers 1 for variable condensers and
coupled resistances 2 for variable resistor in conventional small receiver
R of earphones capable of receiving without antennas.
