Constant directivity horn design
The physics (and mathematics) of horn operation were developed for many years, reaching considerable sophistication before WWII. The most well known early horn loudspeakers were those on mechanical phonographs, where the record moved a heavy metal needle that excited vibrations in a small metal diaphragm that acted as the driver for a horn. A famous example was the hor… Webhorizontal directivity control and has a less-than optimum vertical directivity control. 4 The hyperbolic-exponential horn throat section The second conical-radial bell section controls mid-range beaming The first conical-radial bell section defines the coverage angle A frontal view of a first -generation EV Constant - Directivity horn A ...
