Abstract
An exciting device capable of producing sound by sound-producing vibration body of a main body of an apparatus is provided. An exciting member 32A thin and long in the direction X is provided on a vibration substrate 31 thin and long in the direction X. Both ends of the exciting member 32A are fixed to the vibration substrate 31. Further, a piezoelectric element 33 that functions as vibration generating means is provided in the middle in the direction X of the exciting member 32A. The vibration substrate 31 is directly or indirectly fixed to the sound-producing vibration body. Vibration of the exciting member 32A is transmitted to the sound-producing vibration body through the vibration substrate 31 so that the sound-producing vibration body produces sound.
