Disclosed are variable length mobile phones comprising a parallel moving or inclining-after-projecting speaker for changing the length from speakers to mikes of mobile phones, or a parallel moving or inclining-after-projecting mike for the same purpose, and a projecting button for the purpose of projecting speakers or mikes, starting a call, and locking the returned speakers or mikes after a call, and internal structure design for hiding a spring. The speaker or mike of variable length mobile phones are structurally designed to be projected in parallel or inclining-after-projecting by a force of a spring with pushing a projecting button. The resultant length from the speaker to the mike of the phone becomes 15cm long which is optimal to the length from ears to mouths of most humans. Therefore, the present invention can provide the improved communication condition between a person and her or his phone with convenience. |
