摘要： An automatic tilt speaker has a first subassembly of a speaker unit enclosing an ordinary speaker element. The speaker unit includes a cone-shaped housing having an inner cavity for holding the speaker with its frame or basket fitted snugly in an annular frame. The housing of the speaker unit is pivotally connected to the frame by a pivot arm. The speaker housing has an arcuate exterior wall extending in a radius centered about the pivot connection of the frame. Centrally of the arcuate wall, there is a gear arch, which comprises a vertical column of horizontally elongated teeth extending substantially coplanar with the arcuate wall. On the annular frame at the diametrically opposite side of the pivot connection a tilting system is operatively connected with the teeth. The tilting system includes a motor with a reduction gearbox for driving a worm gear, which in turn drives the gear arch. The annular frame also supports a relay-based motor control board for controlling the polarity and power to the motor. Combined with the power control is a position sensing system including three slight ramp surfaces on the arcuate wall of the speaker unit which translates into three segmented tilting angles to be remotely selected to the user's listening preference.
