Claims

[Claims for Utility Model Registration] A bellows body 2 is attached to the front surface of the speaker unit 1, coaxially or almost coaxially with the speaker unit 1, and capable of expanding and contracting along the direction of the sound emission axis and bending and fixing the sound emission axis. In this speaker horn, the grooves 2a of an annular body 2C having a triangular cross-sectional shape constituting the bellows body 2 are arranged between the inner edges of the troughs 2a, 2a, which are adjacent to each other in the expansion/contraction direction in a group of troughs 2a. A speaker horn characterized in that a cylindrical membrane 3 is stretched over the bellows body 2 in a state that allows expansion, contraction and bending of the bellows body 2. The speaker horn according to claim 1, wherein each of the cylindrical membranes 3 is constructed as a continuous integral piece over the entire length in the axial direction of the cylinder.
