Two folding mobile telephone and mobile telephone

A two folding mobile telephone comprising:

• a first housing having an antenna, a built-in grounding plate, and a hinge bracket set to the inside principal plane of said first housing;
• a second housing having a hinge arm corresponding to said hinge bracket, which is provided over at least an end portion, a display screen set to an inside principal plane to display information, and a voice output plane of a loudspeaker opposite to the hinge arm at the both sides of said display screen;
• and
• a fixing mechanism of temporarily fixing said hinge bracket and said hinge arm;
• wherein,
• said first housing and said second housing are connected so that their inside principal planes face each other when closed,
• a virtual plane orthogonal to a direction when the directivity of an audio signal of said loudspeaker is maximized tilts from a plane including said display screen, and
• a direction of said tilt is in a direction in which the direction when the directivity of the audio signal of said loudspeaker is maximized and said display screen form an obtuse angle.

• a second housing having a hinge arm corresponding to said hinge bracket, provided over at least an end portion, a display screen set to an inside principal plane to display information, a voice output plane of a loudspeaker opposite to said hinge arm at the both sides of said display screen, an antenna;
• and
• a fixing mechanism of temporarily fixing said hinge bracket and said hinge arm;
• wherein,
• said first housing and said second housing are connected so that the housings are faced each other and closed,
• an angle of aperture formed between the inside of a virtual plane orthogonal to a direction in which the directivity of the audio signal of said loudspeaker is maximized and the inside of the plane including said grounding plate is held at substantially 165° or larger by temporary fixing by said fixing mechanism, and
• said virtual plane is substantially the same as or parallel with a plane including the voice output plane of said loudspeaker and the display screen for displaying information.
