  • the mobile phone 100 has a structure in which the entire outer periphery of the panel 120 is supported by being bonded to the casing 110 by the joining member 150. That is, the panel 120 of the mobile phone 100 is firmly fixed to the housing as compared with the panel speaker panel described in the above document. That is, a material having a sufficient hardness is selected for the soft portion 110b of the housing, such as a film-like member that holds a so-called panel speaker, a rubber member that can be expanded and contracted, a spring member, and the like. Therefore, the voltage applied to the piezoelectric element 140 of the mobile phone 100 is higher than the voltage applied to the piezoelectric element mounted on a normal so-called panel speaker.
