Abstract

The present invention implements a wrist watch and a terrestrial DMB broadcast receiver in a single watch form, which is very easy to carry and allows users to watch DMB broadcasts at a desired time.

In addition, by combining several rechargeable batteries in parallel with the wrist strap, it can serve as a wrist strap function and a relatively large capacity battery. It is to act as an antenna of the receiver.

DMB receiver, electronic clock

The present invention implements a wrist watch and a terrestrial DMB broadcast receiver in the form of a single watch, and is a device that can watch a DMB broadcast at a desired time by looking at a watch.

Existing clocks are not only a function of indicating the time, but also simple functions such as calculators, and DMB receivers have recently been released. Most of them are combined with mobile phones, PDAs, and navigation functions. However, these portables are less portable than the wristwatches, and the inconvenience of having to watch the watch and turn on the receiver especially when a user needs to watch at a desired time.

Compared with the conventional DMB receiver, the DMB dual purpose watch of the present invention is

Firstly, the wristwatch and the DMB receiver are combined in the form of the wristwatch size, which is very portable.

Secondly, several rechargeable battery can be arranged in parallel on the wrist strap, so that it can serve as a wrist strap and a relatively large battery.

Third, the radio signal entry plate was attached to the bottom of the clock so that the human body including the arm acts as an antenna of the DMB receiver.

The purpose of the present invention is to implement a wrist watch and terrestrial DMB broadcast receiver in the form of a single wrist watch, so that the user can watch DMB broadcasts at a desired time by watching the clock, and the portable DMB receiver can be operated for a relatively long time as a wrist watch To implement a watch with a function and a clock function.

.

The present invention for achieving the above object is the LCD screen (①, ④) and DMB receiving module (⑤), clock function processor (⑥), parallel connection battery (②) of the watch band function, the human body is used as an antenna Characterized in that it has a radio signal incoming plate for.

The present invention has a case in which a small LCD screen has a transmissive LCD or organic EL emitting screen sharing when receiving a DMB and a clock (Fig. 1-a), and the clock is a reflective LCD screen and the DMB reception is divided into a transmissive LCD. The case can be divided into (Fig. 1-b). In both cases, the processor performs the clock function and controls the clock and DMB receiver by receiving input signals from the control buttons. The only difference is whether a separate reflective LCD is used to reduce power consumption.

The present invention is characterized by performing a relatively large capacity of the battery by combining a plurality of small rechargeable battery in parallel in the form of a watch strap to enable a long DMB viewing (Fig. 3-b). Each small battery has two holes containing electrodes (Fig. 3-a) to allow for continuous connection so that a plurality of cells can be connected in parallel by inserting a conductive wire into the hole. At this time, the conductive line should be variable so as not to be broken by continuous bending, and the exposed part should be protected with a non-conductive material to prevent short circuit. The watch band connecting the batteries can be a single ring or divided into two for easy removal.

In addition, the present invention is characterized by attaching a thin plate connected to the antenna terminal of the DMB receiver so as to be able to contact the arm of the human body on the bottom of the watch to utilize the human body as an antenna of the DMB receiver. In actual experiments, these antennas show the reception performance of 0 to 10dBi in the 200MHz band of DMB frequency band, which is inferior to the DMB miniature antennas of mobile phones.

Here, the form may be slightly different, but if this idea and the fundamental idea are the same, it is not outside the scope of the present invention.

As described above, the present invention is very portable as a conventional wristwatch type compared to a conventional mobile phone, PDA, and a dedicated small terminal. It can reduce the screen and use several batteries to increase the use time and use the human body as an antenna. Excellent performance as a structure that can be. You can also listen to audio broadcasts very conveniently if you use a string of earphones in your clothing along your arm.
