Protective devices for a mobile terminal

Abstract

This invention describes a protective device and associated method for protecting (including the protection from water and dust) a mobile terminal whether or not the terminal is in use, and for providing a hands-free operation of the mobile terminal, wherein the mobile terminal can be a mobile phone, a personal digital assistant (PDA), a pager, a MP3 player, or any similar portable communication device or a mobile electronic device.

Benefits of technology

[0011]The object of the present invention is to provide a protective device and associated method, for environmentally protecting (including the protection from water and dust) a mobile terminal whether or not the terminal is in use, and to provide a hands-free operation of the mobile terminal, wherein the mobile terminal can be a mobile phone, a personal digital assistant (PDA), a pager, a MP3 player, or any similar portable communication device or a mobile electronic device.

[0044]According further still to the fourth aspect of the invention, the mobile phone inserted into the protective device may be switched using the protective device between a hands-free operation utilizing the speaker of the protective device and a privacy mode with a reduced auto gain of the speaker.

Problems solved by technology

To achieve smaller sizes and weights, today's mobile devices often lack any kind of significant protection from the elements.

Most of the mobile terminals today are highly susceptible to water, dust, and dirt, and few have any significant shock protection.

As a result, today's mobile devices are frequently used in environments hostile to the mobile terminal's electronics.

For example, a person who takes a cell phone, PDA, or similar device, to the beach risks harming the device by getting the device sandy or wet.

Even, sitting by the pool or on a boat talking on a mobile phone could be disastrous if the phone is splashed or accidentally dropped in the water.

As a result, such covers provide little protection from water, sand, and dirt, and provide almost no added shock protection if the terminal is dropped.

Hard plastic cases that exist in the art, such as that described by U.S. Pat. No. 6,456,487, are generally not waterproof and may require covers to be sealed against the elements.

As a result, cases that require the terminal to be removed for use provide no protection to the terminal during use, when the terminal is often most vulnerable.

The small size of the headset limits the input, output, and power components that can be placed on the headset.

Furthermore, a person using a headset with a mobile phone while the phone is protected in a handbag or backpack cannot see the display on the phone.

Finally, these headsets are not waterproof themselves.
