![]() The following example shows a doubling of the mouth diameter in comparison to the first example. The larger the diameter in one dimension, the earlier it begins to control directivity. The diameter of the mouth determines the lower limit of directivity control. The mouth is the mouth, which is not the driver. in the following this, the depth was reduced to about half the depth of the previous example. That means that one reduction of the depth causes a widening of the directivity effect and vice versa. The depth of the horn determines the gradient of the course. An idealized 1 "piston radiator was simulated, which in practice is usually replaced by a compression driver. ![]() The following example shows a small horn with the beam angle (-6 dB) of approx. In general, the rule is: the steeper the course of the sound guidance, the stronger the directivity. The contour determines the frequency-dependent directivity. Unfortunately, measurements of real horns are practically always without a baffle, so that the directivity of the sound guide is hardly isolated in practice can be assessed. Otherwise, the directivity would be due to the diffraction in the corpus corpus of the sound guide. ![]() In order to judge exclusively the directivity of the horn, it must be in an infinite baffle to be built in. The infinite baffle ensures that exclusively the directional behavior of the membrane size comes into play. The following example shows two drivers with different rotationally symmetrical ones Membranes in infinite baffle. The larger the diaphragm diameter, the earlier the directivity begins. This means that in the case of rectangular diaphragms the horizontal and vertical radiation characteristics are separated (e.g., in tapes). The diaphragm diameter is responsible for a continuously increasing directivity effect, which is approximately at half the wavelength corresponding to the diameter in the dimension considered. It is thus assumed that a loudspeaker always linearly distorted and directly on the listener is angled. The sonograms are each normalized to 0 °, in order to represent exclusively the radiation behavior. That has the advantage that ideal conditions can be created which allow for a mutual overlap of the exclude any actions. The directives are visualized using BEM simulations. In the following, we will discuss the possibilities for a significant one: directivity and the properties they possess. There are different ways to influence the radiation behavior in a loudspeaker.

FoLLgoTT, if you don't want this posted here, I'll delete it.
