Description

Waterproof cell phone terminal

The present invention relates to a waterproof mobile phone terminal.

Currently, the spread of mobile phone terminals is about 375 million (US 50 million, Japan 40 million, Korea 24 million, Europe 120 million, etc. 143 million) Terminals are gradually shrinking.

In the future, the mobile phone terminal will be input more massive information than the present, therefore, in order to preserve the input valuable information, the mobile phone terminal mainly used in the outdoors has a lot of opportunities of contact with water, and there is a fear of information deletion due to flooding.

At present, the waterproofing of a mobile phone terminal is made of a waterproof plastic bag and the terminal is stored therein, which is inconvenient to use.

Domestic handset makers tried to produce waterproof handset terminals but failed.

Terminal users want to purchase a waterproof mobile phone as long as the purchase price does not increase significantly. Especially, the waterproof mobile phone is essential for people in rainy countries, those who are close to the sea, and who have frequent outdoor trips. Distress can save lives.

It is an object of the present invention to provide a waterproof mobile phone terminal that is completely waterproof to satisfy the above requirements.

The waterproof mobile phone terminal of the present invention is made by waterproofing a portion requiring waterproofing with a sealing member composed of silicone rubber and NBR rubber, and a PEI and PET film member.

The waterproof mobile phone terminal of the present invention includes a speaker, a microphone portion, an alarm bell portion, a liquid crystal panel portion, a keypad portion, an antenna portion, a coupling portion of a main body case to which an upper cover and a lower cover are combined, and a battery, which are waterproof portions. The combined part of the battery case cover and the lower cover is made of a waterproofing member made of silicone rubber and NBR rubber, and waterproofed with PEI and PET film members.
