Abstract
An arrangement for producing sound in an electronic device comprises a magnetic vibrator comprising a first part and a second part provided with permanent magnets, and at least one induction coil. The arrangement further comprises a piezoelectric vibrator comprising piezoelectric material for generating audio-frequency vibrations resulting from deformations of the material by supplying to said material a second electrical signal. The magnetic vibrator and the piezoelectric vibrator have a common audio amplifier. Said first and second electrical signal are supplied from the same audio output to the magnetic vibrator and the piezoelectric vibrator.
