1. A vibration device comprising:
a housing with a receiving space; and
a vibration unit received in the receiving space, comprising:
an elastic support member;
a stator fixed to the housing, comprising a coil fixed to the housing;
a vibrator suspended by the elastic support member, comprising:
a magnet; and
a battery suspended by the elastic support member;
wherein the coil and the magnet interact to drive the vibrator to vibrate relative to the stator for generating haptic feedback;
the elastic support member comprises a bottom plate fixed to the battery, a first fixation portion bending and extending from an edge of the bottom plate, a first elastic portion extending from one end of the first fixation portion, a second elastic portion extending from the other end of the first fixation portion, and a first connection portion connecting the first elastic portion and the second elastic portion; the first connection portion is arranged opposite the first fixation portion; the first fixation portion, the first elastic portion, the second elastic portion, and the first connection portion surrounds the battery, the first connection portion is fixed to the housing for suspending the elastic support member in the receiving house;
the bottom plate is in a rectangle shape, the first fixation portion and the first connection portion extend along a long axis of the bottom plate, respectively; the first elastic portion and the second elastic portion extend along a short axis of the bottom plate, respectively;
the first elastic portion, the second elastic portion, and the first connection portion are spaced apart from the bottom plate;
the first elastic portion comprises a first elastic arm connecting with the first fixation portion, a second elastic arm connecting with the first connection portion, and a connection arm connecting the first elastic arm and the second elastic arm; the elastic support member further comprises a second fixation portion bending and extending from the connection arm to be fixed to the housing;
the elastic support member further comprises a second connection portion connecting the bottom plate and the first fixation portion; a length of the second connection portion along the long axis of the bottom plate is smaller than a length of the bottom plate along its long axis.
