耳机类产品标准符合性研究

Research on Standard Compliance of Headphone Products

我国目前无听力安全的强制标准,风险耳机和不正确的使用习惯均可能造成听力损伤或丧失。为了助力提升耳机产品的设计品质,分析当前国内耳机相关的标准要求,包括声压级限值要求、电性能要求、电气安全要求、可靠性和环境适应性要求,提出了企业可以通过产品余量设计、建立标准化设计平台、增加生产线音频自动化测试等措施以实现对耳机产品质量的有效管控,同时企业还可以通过参与国家标准制修订了解标准进展和要求,提前导入标准并推行落实,最终为技术方案和产品规划保驾护航。

There is no mandatory standard for heating safety in China, unqualified headphones and incorrect use habits can cause hearing damage or loss. In order to improve design quality of headphone products, this paper analyzes the standard requirements of earphones in China, including the sound pressure level limit requirement, the electrical propertie requirement, tile electrical safety requirement, the reliability and environmental adaptability requirements. It is proposed that enterprises can control the quality of headphone products by tolerant designing, building standardized designing plattbml, increasing acoustic automatic test in production line and so on. Companies can also learn about standard progress and requirements by participating in developing national standards, then importing standards and implementing them in advance, thus making the technical solutions and product planning successful
