ABSTRACT:
A speaker with a tweeter angle adjusting device, including a woofer; a horizontal shaft supported on the woofer horizontally and rotatably; a horizontal adjusting knob disposed in parallel with and in the same rotating direction as the horizontal shaft, the horizontal adjusting knob being connected to the horizontal shaft through an interlocking mechanism; a tweeter; a tweeter housing which is secured to the horizontal shaft and which supports the tweeter through a vertical shaft rotatably in a direction perpendicular to the horizontal shaft; and a vertical adjusting knob connected to the tweeter through an interlocking mechanism to rotate in the same direction as the tweeter and journalled in a direction perpendicular to the horizontal shaft. The tweeter direction changing operation can be done easily and accurately because the tweeter shifts in the same directions as the turning directions of the horizontal and vertical adjusting knobs. Besides, since the tweeter can shift also in the transverse direction, the improvement of a high frequency range and a satisfactory stereo feeling can be attained.
