For the complete reasonable answer It is worth to mention the piezoelectric effect that causes mechanical deformation of a piezoelectric material, and therefore emission of sound waves, when metal plates on the opposite sides of a thin layer of the material are charged electrically. This effect is used for small speakers such the ones in mobile phones and beepers when sound quality is not an issue given the narrow acoustic band they can reproduce.
Note also that the reverse effect is used in some microphone and record player transducers.
There are also electrostatic transducers that use a different effect. In these speakers an electrically charged foil is deflected by an electric field provided by grids in front and behind it.
And I am sure there are several other effects that can achieve a transfer of electric energy to mechanic acoustic energy. e.g. the alarm siren where an electric motor moves a specially shaped fan which blows air through a range of opening that intermittently are closed by the movement of the fan itself.
