ABSTRACT:
An electroacoustic motor for association with a horn comprising, in combination, a direct radiation speaker including a chassis, the speaker including a movable diaphragm, an acoustic wave transmitting means comprising an output orifice at the end thereof remote from said diaphragm, and passage means in the acoustic wave transmitting means communicating acoustic waves from the diaphragm to the output orifice. The acoustic wave transmitting means is a separate unit which is detachably secured to the speaker chassis by a fluid-tight connection. The acoustic wave transmitting means comprises a hollow truncated conical member of smaller diameter at the output orifice end thereof than at the end thereof contiguous the diaphragm. A phase adjustment element is positioned in the hollow interior of the truncated conical member, the phase adjustment element being in facing relation at one end thereof to the diaphragm and at the opposite end thereof to the output orifice of the truncated conical member.
