Hands-free Cradle for Mobile Phones {A HANGER OF PARTABLE PHONE HANDSFREE}

The present invention relates to a portable telephone capable of making or receiving a telephone call while a user uses a hands-free telephone when using a portable telephone such as a cellular phone or a PCS phone (personal mobile communication) in a vehicle or a ship. The present invention relates to a hands-free cradle, and more particularly, to a hands-free cradle for a portable telephone capable of communicating with an infrared signal without a line with the hands-free (2) of Patent Application No. 98-52799, which is the same patent application.

Unlike a landline telephone, a portable telephone is a communication device that transmits and receives a wireless signal, so that a user can carry it. Therefore, the portable telephone can transmit a radio signal at any time while making a phone call or receive a radio signal from the public.

Therefore, the portable telephone is used as a power source by mounting a battery in the main body of the telephone, and is capable of transmitting and receiving a radio signal by an antenna for transmitting and receiving, and the battery for supplying power to the telephone using a separate charger. The battery can be recharged.

Recently, portable telephones are becoming smaller and lighter to be convenient for users to carry.

Such portable telephones have a problem that, when the user uses only the telephone, in addition to using the telephone while driving a vehicle or a ship, the attention is reduced, causing an accident of a vehicle or a vessel.

In view of such a problem, a hands-free cradle for making a phone call in a predetermined space or recharging a battery-equipped mobile phone without using a mobile phone directly by a user is mounted on a vehicle or a ship.

The hands-free cradle allows the microphone and speakerphone to be mounted on the data input / output terminal of the mobile phone, the microphone is mounted near the user's location, and the speakerphone is mounted at a location where the user can easily listen. . Thus, in order to connect and install the microphone and speakerphone and the battery power used in the vehicle or the vessel, the interior structure or the decoration and the like have to be removed or separated, which has a cumbersome disadvantage of having to install the wire.

In addition, when a mobile phone has an earphone / microphone input / output terminal, a separate handsfree and wired connection is used.

As described above, when the conventional portable telephone is mounted on a vehicle or a ship, the portable telephone can be connected to the portable telephone in a wired manner. Therefore, when the user makes a secret call, the usage of the handsfree is limited. That is, in such a case, after installing a hands-free cradle in a vehicle or a ship, there is a troublesome problem of carrying a mobile phone while talking on the phone due to a problem of not controlling the microphone and the speakerphone during a private call or a secret call during use.

In addition, when a call is received from a portable telephone, it is inconvenient to insert a handsfree microphone and earphone connected by a wire, and there is a disadvantage that the wire is caught during a call.

In addition, when using the cradle and the hands-free on which the mobile phone is mounted, there was a problem that the mobile phone can be directly controlled when various controls such as checking the use state of the mobile phone or adjusting the volume.

Accordingly, the hands-free of patent application No. 98-52799 (Registration No. 281628), in which I applied for the same patent, was issued, which can be switched on or off directly from the hands-free or muted or automatic state of the call, earrings, earphones, It is possible to adjust the position of the microphone to suit the user's condition, and above all, the mobile phone is equipped with a wireless signal transceiver including an infrared diode for transmitting infrared signals and an infrared transistor for receiving infrared signals. By allowing the user to talk wirelessly with the user, the user's convenience in using the portable telephone is improved.

Therefore, above all, it was necessary to settle the holder which can easily transmit / receive wirelessly with the wireless hands-free.

The present invention has been made in order to solve the above problems, it is possible to easily control the mobile phone from the cradle equipped with a mobile phone while driving a vehicle or ship, and the cradle of the mobile phone and hands-free, in particular the same It is an object of the present invention to provide a hands-free cradle for a portable telephone, which allows a user to make a call using an infrared signal without a line between the hands-free application of Patent Application No. 98-52799.

In addition, the present invention to facilitate the operation state, mute, volume control of the mobile phone through the control panel installed on the cradle to mount the mobile phone, and simultaneously with the surrounding people through external speakers and microphones as well as secret calls The purpose is to make a call.
