PROBLEM TO BE SOLVED: To provide a mobile terminal by which it is possible to satisfactorily acquire audio information simply by contact or close proximity to the ear, without particular care.SOLUTION: The mobile terminal is characterized by having at least: an oscillating plate 12 having a first surface 12a exposed to the outside; an oscillating element 14 for oscillating the oscillating plate 12 on the basis of an electrical signal having audio information; and an electronic circuit 17 for outputting an electrical signal, the difference in amplitude by location within the first surface 12a of the oscillating plate 12, expressed as the ratio of the maximum value to the minimum value, being 60 dB or less. A mobile terminal by which it is possible to satisfactorily acquire audio information simply by contact or close proximity to the ear without particular care can be obtained thereby. |
