HIGH ASPECT RATIO MICROSPEAKER HAVING A TWO-PLANE SUSPENSION

摘要

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.

主权项

1. A microspeaker comprising:
a frame; a diaphragm positioned within the frame, the diaphragm having length sides and width sides, wherein the length sides are longer than the width sides; a magnet positioned below the diaphragm; a yoke having a base portion positioned below the magnet and yoke sidewalls which extend from the base portion, the yoke sidewalls positioned only along a length dimension of the magnet; a voice coil having 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 having an inner edge attached to the length sides and the width sides of the diaphragm and an outer edge extending to the frame, wherein the first suspension member is within a first plane; and a second suspension member having an inner edge attached to the lower end of the voice coil and an outer edge attached to the frame, wherein the second suspension member is in a second plane different from the first plane.
