ROTATABLE SPEAKER CONTROL WITH VIRTUAL DETENTS

摘要

A speaker includes a housing; and a grill disposed at least partially outside of said housing and being rotatable about an axis thereof with respect to said housing to control aspects of operation of said speaker. Rotation of the grill is detectable by circuitry within the speaker. Magnets provide virtual detents. A bearing element is connected to and rotates with the grill; and a blade element is disposed between the grill and the bearing element and is rotatable around the central axis of said grill. A ring portion of the blade element rotates between and in direct contact with one or more pads on the grill and one or more pads on the bearing element. The pads may be a shock-absorbing foam and may have a low-friction coating.
