Abstract: A microspeaker includes a frame and a diaphragm having length sides that are longer than its width sides. A magnet is positioned below the diaphragm. A yoke includes a base portion positioned below the magnet and sidewalls which extend from the base portion, the yoke sidewalls positioned only along a length dimension of the magnet. A voice coil includes an upper end attached to a bottom face of the diaphragm and a lower end positioned within a gap formed between the length dimension of the magnet and the yoke sidewalls. A first suspension member is attached to the length sides and the width sides of the diaphragm and the frame. The first suspension member is within a first plane. A second suspension member is attached to the lower end of the voice coil and the frame. The second suspension member is in a second plane different from the first plane.

Abstract: A speaker driver including a frame and a magnet assembly positioned within the frame. A sound radiating surface may be suspended over the magnet assembly. The sound radiating surface may include a top face and a bottom face, and the bottom face may face the magnet assembly. A suspension member may suspend the sound radiating surface over the magnet assembly. The suspension member may include a top side connected to the bottom face of the sound radiating surface and a bottom side connected to the magnet assembly. A voice coil extends from the bottom face of the sound radiating surface.
