Title
(EN) Speaker system
(ZH) 扬声器系统
Abstract
(EN)
A small-sized speaker system having a very excellent bass-range reproduction capability includes a sound radiation component for guiding acoustic waves radiated from the speaker units to a free space by causing a larger degree of air compression and expansion than in the case where acoustic waves are directly radiated to the free space with the speaker units mounted in corresponding enclosures of the same shape as the speaker units. The speaker system has 20% or more lower f0 than in the case where acoustic waves are directly radiated to the free space with the speaker units mounted in corresponding enclosures of the same shape as the speaker units.

本发明提供一种小型化、且具有非常优良的低音重放功能的扬声器系统。本发明的扬声器系统包括扬声器单元和导音部,导音部向自由空间导出从扬声器单元放射的声波,与将扬声器单元安装在相同形状的密闭箱中而直接向自由空间放射的情况相比,产生高的空气压缩和膨胀。该扬声器系统的f0与将扬声器单元安装在相同形状的密闭箱中而直接向自由空间放射时的f0相比,下降了20%以上。
