Dome Tweeter and Concave Woofer: Simulation Model Using Ring
AES Convention 118 · Paper 6518 · May 2005
Abstract
Theoretical investigation of conventional speaker radiation has been presented at AES 116 and 117, 2004. The concentric ring element was introduced to simulate the speaker’s diaphragm. The technical characteristics of this element were fully described in previous paper (preprint #6246). Four approximations of simulation models were developed to predict the behaviour of a real cone speaker.
Most of the modern tweeters used in multi-way loudspeakers are rigid or soft domes. To describe the geometry of a spherical segment, the approximation with truncated cones can be used. Each cone can be presented as a number of ring elements. Two approximations of a standard dome with ring elements are provided in the present paper. The same method can be used for concave woofer drivers.
