| 中文摘要: |
| 研究丁腈橡胶、丁苯橡胶和三元乙丙橡胶（EPDM）在扬声器折环中的应用，并进行性能对比。结果表明，EPDM胶料经模压硫化制作扬声器折环的工艺操作安全性高，折环弹性好，在高温和低温环境下使用时共振频率变化
较小。 |
| 英文摘要: |
| The applications of NBR，SBR and EPDM on the suspension ring of loudspeaker were studied，and the properties were compared.The results showed that the suspension ring made by EPDM had high processing safety and good elasticity，and the resonance frequency changed less when it was used in high-temperature and low-temperature environment. |
