Document Type and Number:
WIPO Patent Application WO/2018/148865
Kind Code:
A1
Abstract:
Aspects of the present disclosure related to an apparatus and method for radiating sound waves in an omnidirectional manner. A loudspeaker assembly includes a first electro-acoustic transducer positioned along a first longitudinal axis and configured to generate one of low frequency sound waves or high frequency sound waves, a second electro-acoustic transducer positioned along a second longitudinal axis and configured to generate another one of the low frequency sound waves or the high frequency sound waves, and a waveguide and phase plug assembly, coupled between the first electro-acoustic transducer and the second electro-acoustic transducer, and configured to control a direction in which the sound waves generated by the first electro-acoustic transducer and the second electro-acoustic transducer are radiated.
