Abstract: There is provided a portable terminal capable of acquiring sound information successfully simply by being brought near to or into contact with the ear without the necessity of careful handling. The portable terminal includes at least a vibration member having a first surface exposed to an exterior, a vibration element operative to vibrate the vibration member in response to an electric signal corresponding to sound information, and electronic circuitry that outputs the electric signal, a difference in amplitude between individual places within the first surface of the vibration member in a vibrating state being less than or equal to 60 dB in terms of a ratio of maximum value to minimum value of amplitude. A portable terminal can be obtained that is capable of acquiring sound information successfully simply by being brought near to or into contact with the ear without the necessity of careful handling.
