摘要： A tunable earphone is provided. By moving a tuning rod inserted into a hollow shell with a varied depth to drive a tuning plate thus changing the distance between a speaker and the tuning plate, the air in the hollow shell can resonate for different volumes and different path lengths, thereby adjusting a frequency response characteristic of the whole earphone.
