Diffuser for loudspeaker, has function surfaces that are profile-like structured during double diffusion of function surfaces, where substantial enlargement of function surfaces is realized during retention of their main dimensions

摘要

The diffuser (2) has function surfaces, which are directed on a loudspeaker diaphragm and are profile-like structured during double diffusion of the function surfaces. A substantial enlargement of the function surfaces is realized during retention of their main dimensions by the profiled structuring of the function surfaces. The function surface enlargement consists of rounded or square-edged grooves (3). The function surfaces are designed with punctual collections or recesses, and regularly or irregularly spaced apart from each other.
