    • A loudspeaker arrangement comprises an acoustic enclosure (101) which is divided into at least two subchambers (103, 105). An audio radiator (109) is mounted in a first subchamber (103) of the at least two subchambers (103, 105) such that it radiates outwardly of the acoustic enclosure (101). A port (107) is included for pneumatically connecting the first subchamber (103) and the second subchamber (105). The system is designed such that a Helmholtz frequency of the first subchamber (103) and the port (107) is at least five times higher than a resonance frequency of the audio radiator (109). The loudspeaker arrangement may provide an improved trade-off between sound pressure levels, audio quality and size and may in particular provide improved low frequency performance without introducing disadvantages typically associated with conventional ported speaker and passive radiator designs.
    • 扬声器装置包括被分成至少两个子室(103,105)的声学封套(101)。 音频散热器(109)安装在所述至少两个子室(103,105)的第一子室(103)中,使得其辐射到所述声学外壳(101)的外部。 包括端口(107),用于气动连接第一子室(103)和第二子室(105)。 该系统被设计成使得第一子室(103)和端口(107)的亥姆霍兹频率比音频散热器(109)的谐振频率高至少五倍。 扬声器装置可以提供声压级,音频质量和尺寸之间的改进的折衷,并且可以特别地提供改进的低频性能,而不会引入通常与常规移动扬声器和无源辐射器设计相关的缺点。
