Abstract
Disclosed is a speaker having a device capable of generating sound and vibration for notifying reception of an incoming call when a radio incoming signal is received. The speaker comprises a cylindrical frame; magnetic field forming means disposed in the cylindrical frame for forming first and second magnetic flux; a sound generating section for producing electromagnetic force by interaction with the first magnetic flux and thereby generating sound, when a signal having a frequency which is no less than a predetermined frequency, is applied thereto; and vibration generating means for producing electromagnetic force by interaction with the second magnetic flux and thereby generating vibration, when a signal having a frequency which is less than the predetermined frequency, is applied thereto.
