Patent Application
20050164750
The present invention is related to a mobile communication device, and more particularly, to a mobile communication device with a battery strap.
In recent years, a variety of Information Appliances (IAs) such as mobile phones, laptop computers have been prosperously developed. The latest design is developed with the features of compact size, light-weight, and high quality. Therefore, the volume and the location of the power supply are getting more and more important.
Li-ion secondary batteries which have advantages of high operating voltage (3.7 volt), high volumetric energy density, light-weight and long lifespan are largely applied to various of handheld and portable devices including laptop computers, PDAs, mobile phones as a power source. The latest generation of communication devices owning the functions of computers, PDAs, mobile phones emphasize not only its cordless and portable features, but also the feature of being worn around the wrist. Therefore, the requirements for the Li-ion battery as the power source of the 3G mobile phone or mobile IA are high energy, and even light and thin. The needed number of such battery is getting increasing in the market while the application of the mobile device is getting developed.
Furthermore, as the mobile phone is getting popular, people are used to getting a time from the mobile phone. So the watch is replaced by the mobile phone gradually. However, since the watch is worn around the wrist directly, obviously it is more convenient and portable than the conventional mobile phone does when the user wants to know the time. Additionally, in the conventional mobile phone, strict limits are placed upon the miniaturization process due to the volume of the battery which is integrated in the mobile phone. Also, if a mobile phone is dropped due to careless handling or accidentally impacted with something, the mobile phone is likely to be damaged and rendered useless. Hence, the conventional mobile phones have defects that portability is deteriorated due to the above reasons.
It is the main object of the present invention to provide a mobile communication device with a battery strap.
It is another object of the present invention to provide a mobile communication device which can be adapted to the wrist and forearm of the wearer and which can be simply and comfortable used. Further, the mobile communication device of the invention weights as little as possible and possesses an alarm system.
According to one aspect of the present invention, the mobile communication device with a battery strap includes a main device; and a battery strap electrically connected to the main device for providing a battery power to the main device and worn by a user.
Preferably, the main device includes a display and a keyboard.
Preferably, the main deice is a wireless phone.
Preferably, the keyboard is arranged around the main device.
Preferably, the battery strap is flexible.
Preferably, the battery strap is a rechargeable battery.
Preferably, the main device further includes a power jack for charging the battery strap.
Preferably, the power jack is a phonejack.
Preferably, the mobile communication device further includes a headset.
Preferably, the headset is a wireless headset.
According to another aspect of the present invention, the mobile communication device with a battery strap includes a main device; a cover having a connecting portion connected to the main body; and a battery strap electrically connected to the main body for providing a battery power to the main device and worn by a user.
Preferably, the main device includes a keyboard.
Preferably, the main device is a wireless phone.
Preferably, the cover further includes a display.
Preferably, each of two surfaces of the cover includes a display.
Preferably, the battery strap is flexible.
Preferably, the battery strap is a rechargeable battery.
Preferably, the main device further includes a power jack for charging the battery strap.
Preferably, the power jack is a phonejack.
Preferably, the mobile communication device further includes a headset.
Preferably, the headset is a wireless headset.
The foregoing and other features and advantages of the present invention will be more clearly understood through the following descriptions with reference to the drawings, wherein:
The present invention will now be described more specifically with reference to the following embodiment. Please refer to
Referring to
According to the above, because the cell phone can be worn on a user's wrist, it is very convenient to use and has the features of portability as well. Also, a digital camera can be integrated in the communication device of the present invention, in such a way, the main device will integrate a watch, a mobile phone, and a digital camera into one. That will highly increase the applications of the communication device of the present invention. Besides, the main device is powered by the battery strap, the main device can be made into one with lighter weight and compact size so as to decrease power consumption. Furthermore, the technology of the battery strap used in the present invention has been developed for a long time, so it doesn't raise much cost to produce the communication device of the invention.
While the invention has been described in terms of what are presently considered to be the most practical and preferred embodiments, it is to be understood that the invention need not to be limited to the disclosed embodiment. On the contrary, it is intended to cover various modifications and similar arrangements included within the spirit and scope of the appended claims which are to be accorded with the broadest interpretation, so as to encompass all such modifications and similar structures. According, the invention is not limited by the disclosure, but instead its scope is to be determined entirely by reference to the following claims.
