最近,国光电器有限公司引用国外先进技术。推出了一款新颖的YQZ51型软球顶中音扬声器。该中音扬声器单元采用电脑设计的聚合物球顶形振膜,使用大磁路系统和磁液(磁流体)冷却工艺等。该扬声器单元承受功率大,在中频段的频率响应非常平坦,克服了普通球顶中音扬声器的缺陷,(在3000～4000Hz频率处有一明显的峰值),因而使用此单元后可改善音响设备整个频段的音色,是录音室、试听室、舞厅、家庭和汽车音响等作中音重放的理想单元产品。
Recently, Guoguang Electric Co., Ltd. cited foreign advanced technology. Introduced a new type of YQZ51 soft dome midrange speakers. The mid-range speaker unit uses a dome-shaped polymer diaphragm designed by computer, using a large magnetic circuit system and magnetic fluid (magnetic fluid) cooling process. The loudspeaker unit withstands large power and has a very flat frequency response in the middle frequency range, overcoming the drawbacks of a normal dome midrange loudspeaker (with a distinct peak at frequencies of 3000-4000 Hz), thus improving the overall sound system performance with this unit The tone of the band, is the ideal unit for midrange playback of recording studios, audition rooms, dance halls, home and car audio.
