Abstract

Example methods and apparatus can be used to reduce noise in motor assemblies, such as those used in architectural coverings. An example apparatus includes a first driver configured to be coupled to and rotated by an output shaft of a motor, a second driver, and a plurality of vibration-absorbers disposed between the first driver and the second driver. The second driver is configured to be coupled to a rotating member to transfer rotational motion from the first driver to the rotating member via the vibration-absorbers.
