Description

Hands-free device for watch-type mobile communication terminal {HANDSFREE DEVICE FOR WRIST WATCH TYPE MOBILE PHONE}

The present invention relates to a hands free device, and more particularly, to a hands free device for a wrist watch type mobile communication terminal capable of controlling a mobile communication terminal such as a call and message confirmation through a wrist watch.

A mobile communication terminal, i.e., a mobile phone, is a kind of information and communication new media developed so that information can be transmitted anywhere and at any time.

To date, there are cellular mobile phones in the 824-849 MHz frequency band and PCS in the 1750-1780 MHz range based on the transmission frequency of the hand-set.

In addition, the IMT-2000, which will be released in the early 2000s, has been confirmed to use the 1920-1980MHz frequency near the 2000MHz frequency. In developed countries like the US, cell phones have the same frequency as ours, but PCS uses 1850-1910 MHz, which is about 100 MHz higher than ours. Moreover, in Europe, which accounts for more than 60% of the mobile phone market, GSM transmits 880-915MHz. In addition, 914 MHz (CT1) and 885 MHz (CT1 +) are used as cordless telephones for home use.

The phenomenon that appears with the rapid use of the mobile phone is the application of the harmful to the human body. When using a mobile phone, the signal amplified by the high frequency circuit inside the mobile phone is converted into electromagnetic waves through the antenna, which affects the human brain directly adjacent to the antenna.

Studies on the effects of brain and nearby living organisms on electromagnetic waves have been actively studied and reported occasionally, but the exact scientific proof is difficult. However, the fact is that the idealization of normal tissues and the occurrence of cancerous tissues is very related to the electromagnetic wave has already been announced from many domestic and foreign scientists.

However, despite these announcements, handset manufacturers have not taken proper measures. This is because there is no sense of rejection by the user because the primary sensory action such as insensitivity to the invisible electromagnetic waves and hot or itching does not appear.

In order to solve the above problems, a separate hands-free device has been developed. The hands-free device is installed in a vehicle, such as using a speaker and a microphone of the hands-free device to make a call or directly operating a mobile phone while walking.

However, the hands-free device has a problem in that the user must always operate the mobile phone during the walk in the state of being electrically connected to the mobile phone, and must hold the mobile phone in a position that the user can easily use or hold in his hand.

In addition, when carrying a mobile phone, there is another problem that causes a great waste economically because it has no choice but to follow the trends sensitive to the design or size of the mobile phone.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above problems, and to provide a wrist watch type hands-free device capable of checking a call and a message through wireless transmission and reception with a mobile phone.
