Noise reduction for high-airflow audio transducers
First Claim
1. A playback device comprising:
- an enclosure defining an interior portion including a first interior volume and a second interior volume, wherein each horizontal dimension of the enclosure is longer than a vertical dimension of the enclosure, the enclosure comprising;
a front surface having a first horizontal dimension and a vertical dimension; and
a side surface having a second horizontal dimension and the vertical dimension,a speaker disposed within the interior portion of the enclosure and comprising a diaphragm dividing the first interior volume and the second interior volume, and wherein each dimension of a horizontal cross-section of the diaphragm is longer than the vertical dimension of the front surface and the side surface;
a first speaker vent in the front surface having a first cross-sectional area, wherein the first speaker vent is configured to direct a first airflow from the first interior volume to an exterior of the enclosure in a first direction; and
a second speaker vent in the side surface having a second cross-sectional area, wherein the second speaker vent is configured to direct a second airflow from the first interior volume to the exterior of the enclosure in a second direction; and
wherein the second speaker vent has a smaller cross section than the first speaker vent.

Abstract
Example techniques may involve reduction of turbulence noise from a sound transducer that is mounted within an interior housing of a playback device. An example playback device may include an enclosure comprising a first interior volume and a second interior volume. The playback device may further include a speaker mounted within an interior of the enclosure. The speaker includes a diaphragm dividing the first interior volume and the second interior volume and the speaker is moveable along an axis to generate sound. The playback device may also include a first speaker vent providing airflow between the first interior volume and an exterior of the enclosure and a second speaker vent providing airflow between the first interior volume and the exterior of the enclosure. The first speaker vent directs airflow in a first direction and second speaker vent directs airflow in a second direction.

12. An enclosure of a playback device, each horizontal dimension of the enclosure being longer than a vertical dimension of the enclosure, the enclosure comprising:
-
a front surface having a first horizontal dimension and a vertical dimension; a side surface having a second horizontal dimension and the vertical dimension; an interior portion defined by the enclosure, the interior portion of the enclosure defining an interior portion including a first interior volume and a second interior volume, one or more interior surfaces defining an opening to dispose a speaker within the interior portion of the enclosure such that a diaphragm of the speaker divides the first interior volume and the second interior volume, and wherein each dimension of a horizontal cross-section of the diaphragm is longer than the vertical dimension of the enclosure; a first speaker vent in the front surface having a first cross-sectional area, wherein the first speaker vent is configured to direct a first airflow from the first interior volume to an exterior of the enclosure in a first direction; and a second speaker vent in the side surface having a second cross-sectional area, wherein the second speaker vent is configured to direct a second airflow from the first interior volume to the exterior of the enclosure in a second direction; and
wherein the second speaker vent has a smaller cross section than the first speaker vent. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)

20. A method of assembling a playback device, the method comprising:
-
providing an enclosure defining an interior portion including a first interior volume and a second interior volume, wherein each horizontal dimension of the enclosure is longer than a vertical dimension of the enclosure, the enclosure comprising; a front surface having a first horizontal dimension and a vertical dimension; and a side surface having a second horizontal dimension and the vertical dimension, disposing a speaker within the interior portion of the enclosure and comprising a diaphragm dividing the first interior volume and the second interior volume, and wherein each dimension of a horizontal cross-section of the diaphragm is longer than the vertical dimension of the front surface and the side surface; forming a first speaker vent in the front surface having a first cross-sectional area, wherein the first speaker vent is configured to direct a first airflow from the first interior volume to an exterior of the enclosure in a first direction; and forming a second speaker vent in the side surface having a second cross-sectional area, wherein the second speaker vent is configured to direct a second airflow from the first interior volume to the exterior of the enclosure in a second direction; and
wherein the second speaker vent has a smaller cross section than the first speaker vent.
