PROBLEM TO BE SOLVED: To provide a loudspeaker-fitted vibration step motor having loudspeaker function and vibration function. SOLUTION: The loudspeaker-fitted vibration step motor consists of a two-pole flat stator, a rotor consisting of a two-pole permanent magnet magnetically coupled to the flat stator via a gap part and stopping by detent torque, and a driving coil magnetically coupled to the flat stator. A core body 120 composed of two cores and a core gap and forming a magnetic circuit in cooperation with the above permanent magnet is provided on an upper face of the permanent magnet, voice coils 15 with structure optimum for voice are disposed on the gap part and the core gap part, and a diaphragm 1500 is provided to impart the loudspeaker function.
