Abstract
An electronic device can include a housing, an audio component, and a gasket. The housing can define a first internal volume and the audio component can define a second internal volume. The audio component can include membrane and a venting element having a fluid impermeable layer. The venting element can define a fluid path placing the first internal volume and the second internal volume in fluid communication. At least a portion of the fluid path can extend parallel to the fluid impermeable layer. The gasket can define a seal between the first internal volume and an ambient environment adjacent the housing.
Claims19
An electronic device, comprising:
- a housing at least partially defining a first internal volume;
- and
- an audio component defining a second internal volume, the audio component comprising:
- a membrane;
- and
- a venting element defining a fluid path, the fluid path extends from the first internal volume to the second internal volume, the venting element comprising:
- a first layer at least partially defining a first channel;
- a second layer at least partially defining a second channel;
- and
- a fluid permeable intermediate layer disposed between the first layer and the second layer.
An audio component, comprising:
- a case at least partially defining an internal volume;
- a membrane at least partially defining the internal volume;
- and
- a venting element in fluid communication with the internal volume, the venting element defining a fluid path extending from the internal volume to an environment external to the case, the venting element comprising:
- a first fluid impermeable layer;
- a second fluid impermeable layer;
- and
- a porous layer disposed between the first fluid impermeable layer and the second fluid impermeable layer, the porous layer defining at least a portion of the fluid path.
A venting element for a portable electronic device, comprising:
- a first fluid impermeable layer defining a first surface of the venting element;
- a second fluid impermeable layer defining a second surface of the venting element;
- and
- a coiled member disposed between the first fluid impermeable layer and the second fluid impermeable layer, the coiled member defining a conduit defining a fluid path extending to an external environment.
