具虚拟棘爪之可旋转扬声器控制手段;ROTATABLE SPEAKER CONTROL WITH VIRTUAL DETENTS

摘要

扬声器包括壳体；以及网格，该网格至少部分安置在该壳体之外侧，且可绕该网格之轴相对于该壳体旋转以控制该扬声器之操作态样。该网格之旋转可由该扬声器内之电路侦测。磁铁提供虚拟棘爪。轴承元件连接至该网格且与该网格一起旋转；且叶片元件安置在该网格与该轴承元件之间，且可围绕该网格之该中心轴旋转。该叶片元件之环部分在该网格上之一或多个衬垫、及该轴承元件上之一或多个衬垫之间旋转，且与该网格上之一或多个衬垫、及该轴承元件上之一或多个衬垫呈直接接触。该等衬垫可为减震泡沫体且可具有低摩擦涂层。; 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.
