摘要： The present invention sets out to solve the problems above by presenting a dual-mode speaker system for acoustic reproduction. The dual-mode speaker system for acoustic reproduction presents a system with high-energy conversion efficiency and provides flexibility between an active speaker driver and other radiators, improved sound quality, a larger range of low frequency sounds, and the capability to improve audio frequency playback range in small-scale audio environments. A dual-mode acoustic radiator speaker system is provided having an enclosure with a plurality of openings, an active speaker driver having a first motor assembly and a dual-mode radiator having a second motor assembly. In some embodiments, the dual-mode acoustic radiator speaker system further comprises one or more passive radiators adjoined to the enclosure. Next, within the dual-mode acoustic radiator speaker system a power supply is connected to the electronic signal processing and amplification system.
