关于通用型φ200mm 以下纸盆扬声器的功率标称问题,四机部部标 SJ1020—75,SJ1021—75已有规定,这些扬声器在满足我国整机(电视机,收音机等)需要方面,不论是电声性能或可靠性方面均已达到一定的要求,该标准不包括组合扬声器、扬声器箱以及高频扬声器。目前国际上对通用型扬声器的功率标称方法不尽一致,有的标大,有的标小,有的不标,功率名称有标称(额定)功率,最大功率,瞬时最大功率,音乐功率等,各自的解释也不同,有的公司对自己的产品标得过高,已超出本身承受的能力,有的公司为了竞争,盲目标高,致使扬声器寿命大大缩短,考虑到这种情况,本刊发表下面文章,以期引起国内各扬声器厂及整机厂对这方面工作的重视,相应开展研究、试验和验证工作,在保证扬声器质量的前提下,为出口扬声器的功率标法得到妥善解决。
About universal speaker power of φ200mm below the speaker nominal power problems, the four machine department standard SJ1020-75, SJ1021-75 have been provided, these speakers in our country to meet the machine (TV, radio, etc.) needs, whether it is electricity Sound performance or reliability have reached certain requirements, the standard does not include a combination of speakers, speaker boxes and tweeters. At present, the power of the general-purpose speaker nominal method is not the same, some standard large, some standard small, some not standard, the power name has nominal (rated) power, maximum power, instantaneous maximum power, music power Etc., their respective interpretation is also different, some companies mark their own products too high, beyond their own ability to withstand, and some companies in order to compete, blind elevation, resulting in greatly reduced speaker life expectancy, taking into account this situation, the issue Published the following article, with a view to arousing domestic loudspeaker factory and the whole plant attach importance to this work, the corresponding research, testing and verification work, to ensure the quality of the speaker under the premise of export speaker power standard method is properly resolved.
