ELECTRONIC DEVICES USING EARPHONES AND WIRELESS EARPHONES

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: 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.
