Abstract
A driver assembly including a driver module having a driver frame and a diaphragm coupled to the driver frame, the driver frame defining a front volume chamber coupled to a first side of the diaphragm and a back volume chamber; an internal control leak formed through the driver frame to couple the front volume chamber to the back volume chamber; and a first driver vent and a second driver vent formed through the driver frame to couple a second side of the diaphragm to the back volume chamber, wherein a centroid of the first driver vent is aligned with a centroid of the second driver vent.
Claims21
A driver assembly comprising:
- a driver module having a driver frame and a diaphragm coupled to the driver frame, the driver frame defining a front volume chamber coupled to a first side of the diaphragm and a back volume chamber;
- an internal control leak formed through the driver frame to couple the front volume chamber to the back volume chamber;
- and
- a first driver vent and a second driver vent formed through the driver frame to couple a second side of the diaphragm to the back volume chamber, wherein the first driver vent or the second driver vent comprises an asymmetrical shape and a centroid of the first driver vent is aligned with a centroid of the second driver vent.
An ear bud having a driver assembly comprising:
- an enclosure having an enclosure wall that forms an interior chamber and an acoustic outlet port coupling the interior chamber to an ambient environment;
- a driver module positioned within the interior chamber, the driver module having a driver frame to which a diaphragm and a magnet assembly are coupled, the driver frame dividing the interior chamber into a front volume chamber coupled to a first side of the diaphragm and a back volume chamber;
- an internal control leak formed through the driver frame to couple the front volume chamber to the back volume chamber;
- a first driver vent and a second driver vent formed through the driver frame to couple a second side of the diaphragm that faces the magnet assembly to the back volume chamber;
- and
- a rear vent formed through the enclosure to couple the back volume chamber to the ambient environment.
