Abstract
A microspeaker includes a frame defining a space; and an actuator positioned within the space, the actuator including a diaphragm configured to vibrate in a first direction during operation. A center axis of the diaphragm extends in the first direction. A plate assembly mechanically couples to the frame and defines a path for venting fluid from the space. The plate assembly includes: a first plate extending in a plane and defining first apertures that are offset from the center axis in the plane; and a second plate defining a second aperture intersected by the center axis. The second plate includes: an inner recessed region abutting the second aperture; and an outer non-recessed region. The first plate is mechanically coupled to the second plate, the first plate and the inner region of the second plate defining a channel that fluidly couples the first apertures to the second aperture.
