Description

walkie talkie

The present invention relates to a portable cordless phone, and in particular, when the wireless handset is coupled to the portable cordless phone body, the call can be made through the portable cordless phone body. It relates to a portable cordless phone capable of doing so.

The present invention as described above is not limited to the portable wireless telephone, but may be applied to a portable radio.

In general, the use of portable cordless telephones has become commonplace, and it has been possible to simply perform tasks that were traditionally handled at offices at a fixed address within a car or on the street.

However, new risks are faced in many areas in the form of side effects accompanying these changes in the work environment.

For example, if a driver wants to talk while driving a car, the driver must hold the phone with one hand while driving with one hand and keep the phone close to the ear until the guide signal of the base station is heard.

In addition, there is a problem that the user is exposed to harmful electromagnetic waves generated from the portable radio telephone for a long time, the brain wave of the user is disturbed, harmful to the human body by receiving thermal energy of microwaves.

As a device to compensate for this problem, a hand-free portable wireless telephone has been developed and used.

The conventional hand-free portable cordless phone as described above is a device which allows a user to hear a ring tone using a speakerphone at a predetermined distance from the phone and to make a call using a microphone. .

However, such a hand-free portable cordless telephone has a problem in that the hand-free function cannot be used when separated from a vehicle.

In addition, the hand-free portable cordless phone as described above has a problem in that the contents of a call cannot be accurately transmitted due to the ambient noise in a noisy place.

It is an object of the present invention to provide a portable wireless telephone capable of making a call in a hand free state and allowing the contents of the call to be delivered more accurately to the user.

In addition, another object of the present invention is to provide a portable wireless phone without being in close contact with the ear, the portable radio that can prevent harmful electromagnetic waves generated from the portable wireless phone to be directly transmitted to the user by making a call while the earphone is plugged into the ear To provide a telephone.

The portable radio telephone according to the present invention for achieving the above object comprises a radio handset and a portable radio telephone body which are capable of transmitting and receiving voice and signal information to and from each other through a radio channel, while the portable radio telephone body includes the radio. A holder for accommodating the handset is formed, and when the wireless handset is separated from the holder, the wireless main body can relay voice and signal information between the wireless handset and the wireless base station to make a call using the wireless handset, and the wireless handset is stored in the holder. If it is, it is characterized in that the main body can be used to make a call.

In addition, the wireless handset is characterized in that the user is formed to be able to talk in a hand-free state.

In addition, when a signal indicating that the touch switch 230 is 'off' is input through the relay transceiver 152, the microcomputer 141 of the main body 100 receives only the received sound received by the relay transceiver 152 by the transceiver 154. It is controlled to transmit to the wireless handset 200 through the antenna 106 ', and control the microphone switch 144 in the' on 'state to input the voice through the microphone 105 of the portable cordless telephone main body 100. To be.

At this time, the touch switch 230 is maintained in the 'off' state in the contracted state of the antenna 203.

Accordingly, when the user detaches the wireless handset 200 from the holder 101 of the portable cordless telephone body 100 and then inserts the earphone 201 into the user's ear with the antenna 203 contracted, the touch switch 230 may be used. As it is maintained in the 'off' state receives the voice signal through the earphone 201 of the wireless handset 200, and transmits the voice signal through the microphone 105 of the portable cordless phone main body 100.

Then, when the user detaches the wireless handset 100 from the holder 101 of the main body 100, and then expands the antenna 203 and inserts it into the user's ear, the touch switch 230 is kept in an 'on' state. The earphone 201 and the microphone 202 of the handset 200 will be able to talk.

Therefore, the handset can be talked on using the wireless handset 200, or the handset wireless phone main body 100 can be used for the call. In addition, it is easy to carry as the wireless handset 200 can be stored in the holder 101 formed in the portable wireless telephone body 100.

As described above, in the present invention, the wireless handset 200 is additionally installed in the portable cordless phone so that the portable cordless phone can be used in a hand-free state without being held in the place. In this way, the wireless handset 200 is used. When you make a call, you can prevent harmful electromagnetic waves from a portable cordless phone from being transmitted directly to your body.

In addition, the handset is heard through the earphone 201 of the wireless handset 200, so that the contents of the call can be accurately heard even in a lot of surrounding noise, and the microphone 202 of the wireless handset 200 or the portable cordless phone body The microphone 105 of the 100 can be selectively used according to the location.

In addition, the light emitting diode 107 and the light emitting unit 501 are provided at the top of the antenna 106 in the lower housing of the antenna 106, so that the portable telephone can be easily found even when the portable telephone is turned upside down in a dark place. The power of the 200 is supplemented with the solar cell 221 to compensate for the lack of power of the wireless handset 200.

In addition, since the hand-free mode is automatically adjusted in the process of storing or detaching the wireless handset 200 into the portable wireless telephone main body 100, it is convenient to use.
