An efficient loudspeaker horn designed by numerical optimization: an experimental study
Using rapid prototyping, we manufacture an acoustic horn designed by gradient-based shape optimization to have virtually perfect impedancematching properties. The horn is 161.5 mm long, has a mouth diameter of 300 mm, and a throat diameter intended for a 1.5 inch driver. We optimize the horn with the aim of having perfect radiation efficiency at 31 frequencies in the range 1.6–9.05 kHz, while s...
متن کاملMulti-loudspeaker Reverberation System
In this paper we present a reverberation system based on a multiloudspeaker configuration. The aim of this work is to produce a natural sounding reverberation system with a similar pattern to the produced in real rooms. A new method for sound spatialization is presented, and it is used to locate on the virtual room’s surfaces the early reflections produced in a reverberant space. Each loudspeak...
متن کاملElectrostatic graphene loudspeaker
Graphene has extremely low mass density and high mechanical strength, and key qualities for efficient wide-frequency-response electrostatic audio speaker design. Low mass ensures good high frequency response, while high strength allows for relatively large free-standing diaphragms necessary for effective low frequency response. Here, we report on construction and testing of a miniaturized graph...
متن کاملSmart Digital Loudspeaker Arrays*
This paper considers from a theoretical stance the fundamental requirements of a programmable polar response, digital loudspeaker array, or smart digital loudspeaker array (SDLA), which consists of either one-dimensional or a two-dimensional array of micro radiating elements. The principal problem addressed here is the design of a set of digital filters which together with a uniform array of sm...
