NO
Current is produced when charges are accelerated by an electric field to move to a position of lower energy.
the only sound is from the power source
An electric current produces a magnetic field.
Flow of the current.

sound wave cannot produce magnetic field because magnetic field is created due to flow of electric currents sound is a mechanical wave, sound is produced due to vibration in a medium so sound wave cannot create electric current or magnetic field

Flow of the current.
When an electric current is passed through water oxygen gas is produced on cathode because oxygen is positive and cathode is negative . So, oxygen is produced.
Actually your eardrum does not have electric current and in which it only uses sound so if you get an electric shock it does not harm your ear drums.
Electric field is produced
Sound waves are longitudinal waves. These would vibrate a diaphragm which has been attached with a coil kept in a magnetic field. As the coil vibrates then current is induced. This is how sound wave gets changed into electric current.
direct current
The telephone does that!
