MASS LOADED EARBUD WITH VENT CHAMBER
First Claim
1. An intra-concha earphone, comprising:
- a housing having a driver therein, the housing including a rear wall behind the driver and a rear space between the driver and the rear wall, wherein the driver is to convert an electrical audio signal into a sound;
a chamber partition in the rear space, the chamber partition defining a back volume behind the driver, wherein the chamber partition includes an acoustic port and a bass aperture;
a vent chamber between the chamber partition and the rear wall, wherein the vent chamber is acoustically coupled with the back volume through the acoustic port; and
a bass duct extending between the bass aperture and the vent chamber, wherein the vent chamber is acoustically coupled with the back volume through the bass duct.

Abstract
Intra-concha earphones are disclosed. In an embodiment, an intra-concha earphone includes a housing having a rear space divided into a back volume, a bass duct, and a vent chamber between a driver and a rear wall. The vent chamber may be acoustically coupled with the back volume through both an acoustic port and the bass duct. Furthermore, the vent chamber may be acoustically coupled with a surrounding environment through a vent port, which may be a sole acoustic opening in the rear wall. Thus, sound emitted by the driver may propagate through the acoustic port and the bass duct to meet in the vent chamber before being discharged through the vent port to the surrounding environment. Other embodiments are also described and claimed.
