Abstract:
1. Annular diaphragm compression driver for a horn loudspeaker for electro-acoustic conversion comprising: an annular diaphragm, which bears at least one moving coil, a compression driver housing having wherein an open sound exit end of said sound discharge channel is in slot form adapted to be connected to a horn and a sound entry start of the sound discharge channel, which sound entry start is opposite the open sound exit end and adjacent to said at least one compression chamber, is annular, and the sound path between the said at least one compression chamber and said sound entry start of said sound discharge channel contains an annular collecting space, wherein said annular collecting space and said sound discharge channel contain a central sound guidance body having a portion which merges from an annular cross section into a linear cross section which matches the slot form of said sound exit end of said sound discharge channel, and said sound discharge channel is formed between said sound guidance body and a circumferential wall of said sound wave routing element, and wherein said circumferential outer wall of said central sound guidance body forms an inner wall of the collecting space and an inner wall of said sound discharge channel.
