笔者身居闹市,居住面积小,过去常为不能享受大个儿音箱而烦恼。自从制作使用了书架式音箱以后,这种烦恼不复存在,是因为书架音箱一样可以“发烧”。它声音明亮清晰,音域宽广,解析度不错,更重要的是,它摆放灵活,又不影响别人。 要制作好的音箱,扬声器的选择至关重要。惠威产品一向口碑很好,经过再三斟酌,终于决定选用惠威S8-96R型(8英寸防磁低音扬声器)作低音单元,用惠威SS1-Ⅱ型(防磁式高音扬声器)作高音单元。 笔者认为,这两种扬声器最适合于做书架音箱,因为S8-96R型采用长冲程设计,线性位移可达4.5mm,动态范围大,失真小,其低频谐振频率可达28Hz;而SS1-Ⅱ型则因采用了美国液磁,使参数顿时上了一个档次,且它的音膜也来自德国,频带宽广,参数也很稳定。 书架式音箱采用倒相式设计,其尺寸如附图所示。音箱结构设计主要考虑低频特性,使箱体能适应低音单元的声辐射特性,因为其对高音单元的影响极小。分频器可以采用惠威PS8/B,当然也可以自制,其电路见附图。
I live in the downtown area, living area is small, in the past often can not enjoy the big speaker and trouble. Since the production of bookshelf speakers, this worry no longer exists, because bookshelf speakers can be “fever.” It sounds bright and clear, wide range, good resolution, more importantly, it placed flexible, without affecting others. To make a good speaker, the choice of speakers is crucial. Swans product has always been a good word of mouth, after repeated consideration, and finally decided to use Swans S8-96R (8-inch anti-magnetic bass speakers) for the bass unit, Swans SS1-Ⅱ type (anti-magnetic tweeter) for tweeter. The author believes that the two speakers are most suitable for bookshelf speakers, because the S8-96R-type long stroke design, linear displacement up to 4.5mm, a large dynamic range, low distortion, the low frequency resonance frequency up to 28Hz; and SS1-Ⅱ Type because of the use of the United States liquid crystal, the parameters suddenly on a grade, and its sound film is also from Germany, a wide frequency band, the parameters are also very stable. Bookshelf speakers with inverted design, the size shown in the figure. The design of the loudspeaker mainly considers the low-frequency characteristics so that the housing can adapt to the acoustic radiation characteristics of the bass unit because of its minimal impact on the treble unit. Dividers can be used Swans PS8 / B, of course, can also be made, the circuit see the photo.
