Bluetooth sound box for matrix audio system and directional playing method

Abstract

The invention discloses a Bluetooth sound box for a matrix audio system and a directional playing method. The Bluetooth sound box comprises a sound box shell; a horn mouth is formed at the top end ofthe sound box shell; chutes formed vertically are disposed on the outer walls of both sides of the sound box shell; the inner walls of the chutes are in sliding connection with sliding blocks; rivetsare arranged on the outer walls of one sides of the sliding blocks; the sliding blocks are rotationally connected with struts by the rivets; threaded holes are formed on the outer walls of one sides of the struts, and the inner walls of the threaded holes are in threaded connection with positioning bolts; a top cover is arranged between the top ends of two struts; and a clamping ring is arranged at the bottom end of the top cover. According to the invention, due to an arranged bearing, a rotating rod can rotate by the bearing so as to drive the top cover to rotate; the top cover can drive thesound box shell to rotate by the struts, so that when in use, the sound box can be conveniently regulated according to a listening angle demand of a user, thereby avoiding a problem that a sound outlet direction of a conventional Bluetooth sound box is inconvenient to regulate.
