摘要： A flat thin dynamic speaker which includes a motor unit, a suspension unit, a radiating unit and a frame arranged in such a manner that the motor unit and the suspension unit are at the same plane while the radiating unit is on top of the motor unit such that the thickness of the speaker assembly is reduced while the performance of the speaker assembly is maintained or even improved. Also, the speaker can be made into a quadrangular, polygon or a spherical structure. The speaker further has a surround at a level lower than the radiating unit without utilizing the radiating surface of the radiating unit such as a maximized radiating surface is provided, and includes a dual side voice-coil actuation to the radiator unit, thereby providing a slim and flat speaker assembly with high power output.

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.
