Abstract (en)
The invention relates to a rotation joint for conjoining two stacked speakers for a rotational satellite speaker system. The joint comprises first and second bases, the first base being integrally formed with a first fixing plate and a first connecting means, the second base being integrally formed with a second fixing plate and a second connecting means. The first and second fixing plates are extending parallelly in perpendicular to a common rotation axis of the joint. The first connecting means is rotatably engaged with the second connecting means. The first and second bases are detachably inserted into corresponding receiving spaces defined in upper and lower speakers. Advantageously, the rotation joint can be made at low cost and easily assembled and disassembled. Preferably, the first and second bases of the joint are interchangeable with each other.
