摘要： An informing apparatus for a mobile communication apparatus has two magnetic gaps A, B formed in a magnetic circuit, in which voice coils are set respectively. A first vibrant part includes one voice coil connected to a diaphragm, and a second vibrant part includes another voice coil connected, via supporters, to a casing set outside the magnetic circuit, the supporters and the magnetic circuit. A sound receiving function and/or a call-tone receiving function, which is performed with a sound signal and/or a call-tone signal sent to the voice coil 8 in the first vibrant part, and a silent mode call-reception informing function, which is performed with a call-reception signal sent to the voice coil in the second vibrant part whereby the supporters and the magnetic circuit are vibrated thereby making the mobile communication apparatus itself resonate, work independently.
