矿用音箱生产一致性检测方法

Method for Measuring Consistency of Mine Sound Box

针对批量生产过程中无法保证每台音箱音质性能的一致性、人耳主观判断造成听觉损伤、检测效率低等问题,提出一种有效的量化检测方法,利用电声测试仪对音箱阻抗、频率响应、失真度等性能进行测试,判断批量生产音箱性能是否具有一致性,减轻人为主观判断工作量,提高量产检测效率。

For the sound box consistency of the performance is not guaranteed, the subjective judgment of ear caused the hearing damage, low detection efficiency and so on, proposed an effective quantitative method for detection, The impedance, frequency response, distortion and other properties were tested by electro acoustic tester. Determine whether the production performance is consistent, reduce the workload of human, improve the detection efficiency of production.
