Abstract
An acoustical transducer such as an audio loudspeaker or a microphone, having a suspension component whose outermost edge extends axially rather than radially and couples with an axial mounting surface in the transducer's frame rather than with a radial flat surface of the frame. The suspension component may be a surround or a spider. Eliminating the radial portions of the suspension component and the frame enables the use of a larger diaphragm within a transducer of unchanged outer dimensions, increasing the amount of air moved by or moving the diaphragm. It also enables closer on-center packing of multiple transducers onto the same baffle such as the front baffle of a speaker enclosure, or, put another way, it enables a higher percentage of the mounting baffle's front surface area to be covered with moving diaphragm area. Radial mounting flanges and their mounting holes are limited to portions of the frame which will not increase the gap space between adjacent transducers or other boundaries. The angled corner tabs of a square or hexagonal frame housing a round diaphragm would occupy the baffle surface area that would otherwise be unutilized with circular-frame speakers.
