EARPHONES |
| 摘要 |
A headphone includes a housing defining an enclosed volume, an electro-acoustic transducer dividing the enclosed volume into a front volume and a rear volume, a first port in the housing coupling the front volume to an ear canal of a user, a second port in the housing coupling the front volume to space outside the ear, a third port in the housing coupling the rear volume to space outside the ear, and an ear tip configured to surround the first port and seal the ear canal from space outside the ear. The second port has a diameter and a length that provide an acoustic mass with an acoustic impedance with a high reactive component and a low resistive component. |

1. A headphone comprising:
a housing defining an enclosed volume; an electro-acoustic transducer dividing the enclosed volume into a front volume and a rear volume; a first port in the housing arranged to couple the front volume to an ear canal of a user when the headphone is worn; a second port in the housing arranged to couple the front volume to space outside the ear of the user when the headphone is worn; a third port in the housing arranged to couple the rear volume to space outside the ear of the user when the headphone is worn; and an ear tip configured to surround the first port and seal the ear canal from space outside the ear when the headphone is worn; wherein the second port has a diameter and a length that provide an acoustic mass with an acoustic impedance with a high reactive component and a low resistive component. |
