  • Patent number: 11659336
    Abstract: A vibration apparatus includes a substrate, an elastic piece, a magnetic component and at least two coils. The substrate abuts on a display panel of a mobile terminal; the at least two cods are fixed on an inner side surface of the substrate; the inner side surface faces away from the display panel; the at least two coils are disposed coaxially; and axes of the at least two coils are perpendicular to the substrate. A first side surface of the elastic piece abuts on the inner side surface of the substrate; the magnetic component is connected to a second side surface of the elastic piece; the second side surface is disposed away from the first side surface. The at least two cods are at least in part accommodated in an annular accommodating groove of the magnetic component.
