The invention discloses a protection mobile phone utilizing light reflection and light sensing, comprising a mobile phone body and an input device. The mobile phone body comprises a first wireless communication unit, a first signal processing unit, a protection unit, a speech input unit, a speech output unit and a light sensing unit, wherein the first signal processing unit is electrically connected with the first wireless communication unit, the protection unit, the speech input unit, the speech output unit and the light sensing unit respectively; the projection unit is used for projecting images by lights with different light spectrums; the light sensing unit is used for sensing the lights and producing input signal according to the light spectrums of the lights. The input device comprises a light reflection unit for reflecting the light to the light sensing unit. The projection mobile phone does not need a liquid crystal screen and a plastic key, so that the cost is reduced and the user experience is improved.
Description
technical field [0001] The invention relates to a mobile phone, in particular to a projection mobile phone. Background technique [0002] With the rapid development of science and technology, the life of modern people has entered an information age, and timely information communication has become very important. When instant communication is required, people generally choose traditional telephones or use cell phones. [0003] Traditional phones are usually non-movable fixed phones, and users need to stay in a fixed location before they can use the phone to communicate. As a new type of communication device, the mobile phone has replaced the traditional mobile phone to a large extent. It has the advantages of being portable and making calls anytime and anywhere. However, mobile phones also have disadvantages that traditional mobile phones do not have. For example, the cost of manufacturing LCD screens and plastic keys is relatively high, and the radiation is relatively larg...
