Abstract

A loudspeaker includes an enclosure having an open front side defining a forward direction for projecting sound, a first support surface configured to support the loudspeaker in a monitor orientation, and a second support surface configured to support the loudspeaker in an upright orientation. In the monitor orientation, the forward direction is arranged at an oblique upward angle relative to a surface on which the enclosure is placed. The loudspeaker also includes an audio transducer positioned within the enclosure and configured to emit sound from the open front side of the enclosure, and a baffle securing the audio transducer to the enclosure. The baffle has a front surface facing in the forward direction and a channel formed in the front surface. The channel is configured to direct water out of the enclosure in the monitor orientation.

Claims (32)

1. A loudspeaker comprising:

an enclosure having an open front side defining a forward direction for projecting sound, a first support surface configured to support the loudspeaker in a monitor orientation, and a second support surface configured to support the loudspeaker in an upright orientation, wherein in the monitor orientation, the forward direction is arranged at an oblique upward angle relative to a surface on which the enclosure is placed;

an audio transducer positioned within the enclosure and configured to emit sound from the open front side of the enclosure; and

a baffle securing the audio transducer to the enclosure, the baffle having a front surface facing in the forward direction and a channel formed in the front surface, the channel configured to direct water out of the enclosure in the monitor orientation.

2. The loudspeaker of claim 1 , wherein the channel includes a curved portion and a straight portion.

3. The loudspeaker of claim 1 , wherein the baffle has an edge adjacent a wall of the enclosure, and wherein the channel has an open end at the edge of the baffle.

4. The loudspeaker of claim 1 , wherein the baffle includes an opening configured to receive the audio transducer, and wherein a portion of the channel follows a path established by a portion of a circumference of the opening.

5. The loudspeaker of claim 4 , wherein the channel includes a first end spaced from a first edge of the baffle and a second end open to an opposite second edge of the baffle.

6. The loudspeaker of claim 1 , wherein a portion of the audio transducer is spaced further in the forward direction of at least a portion of the channel so that the audio transducer covers the portion of the channel.

7. The loudspeaker of claim 1 , wherein the channel has a first wall adjacent the audio transducer and a second wall adjacent a port of the loudspeaker, and wherein the second wall extends further in the forward direction than the first wall in a region of the port.

8. A loudspeaker comprising:

an enclosure having an open front side defining a forward direction for projecting sound, a first support surface configured to support the loudspeaker in a monitor orientation, and a second support surface configured to support the loudspeaker in an upright orientation, wherein in the monitor orientation, the forward direction is arranged at an oblique upward angle relative to a surface on which the enclosure is placed;

an audio transducer positioned within the enclosure and configured to emit sound from the open front side of the enclosure;

a baffle positioned in the open front side of the enclosure and having an opening configured to receive the audio transducer, the baffle having a front surface facing the forward direction and having a channel formed in the front surface, the channel having a first wall adjacent the audio transducer and a second wall adjacent a port of the loudspeaker, and wherein the second wall extends further in the forward direction than the first wall in a region of the port,

wherein the baffle has a first portion having the channel and a cover disposed further in the forward direction than the first portion, and wherein an edge of the cover and the first portion define an exterior opening of the port.

9. The loudspeaker of claim 8 , wherein, the channel has a first straight portion and a curved portion following a path established by a portion of a circumference of the opening, wherein the first straight portion is arranged at a first end of the curved portion, and wherein the channel has a second straight portion arranged at a second end of the curved portion.

10. The loudspeaker of claim 9 , wherein the first straight portion and the second straight portion are parallel.

11. The loudspeaker of claim 10 , wherein the first straight portion extends along a port of the loudspeaker, the first straight portion of the channel having a first wall adjacent the audio transducer and a second wall adjacent the port, and wherein the second wall extends further in the forward direction than the first wall.

12. The loudspeaker of claim 9 , wherein the channel has a curved connecting portion arranged between the second straight portion and the curved portion, and wherein the curved connecting portion curves toward the opening.

13. The loudspeaker of claim 9 , wherein the channel includes a first end on the first straight portion and spaced from a first edge of the baffle and a second end on the second straight portion and open to an opposite second edge of the baffle.

14. The loudspeaker of claim 8 , wherein the baffle has an edge adjacent a wall of the enclosure, and wherein the channel has an open end at the edge of the baffle.

15. The loudspeaker of claim 8 , wherein a portion of the audio transducer is spaced forward of at least a portion of the channel so that the audio transducer covers the portion of the channel.

16. The loudspeaker of claim 8 , wherein the channel has a first wall adjacent the audio transducer and a second wall adjacent a port of the loudspeaker, and wherein the second wall extends further in the forward direction than the first wall in a region of the port.

17. A method of channeling water out of a loudspeaker, the method comprising:

providing the loudspeaker having an enclosure having an open front side defining a forward direction for projecting sound, an audio transducer positioned within the enclosure and configured to emit sound from the open front side of the enclosure, and a baffle securing the audio transducer to the enclosure, the baffle having a front surface facing in the forward direction, a channel formed in the front surface, a first portion having the channel and a second portion having a cover disposed further in the forward direction than the first portion, the cover and an end of the first portion defining an exterior opening of the port;

placing the loudspeaker in a monitor orientation on a floor surface such that the forward direction is at an upward oblique angle with respect to the floor surface;

receiving water on the front surface of the baffle;

directing the water over an edge of the cover; and

directing the water along the channel by gravity.

18. The method of claim 17 , further comprising providing a perforated grille covering the open front side of the enclosure and the baffle, wherein the receiving the water on the front surface of the baffle includes receiving water through the perforated grille.

19. The method of claim 17 , wherein directing the water along the channel includes directing the water along a path established by a portion of a circumference of the opening.

20. The method of claim 17 , further comprising conveying the water out of an open end of the channel at an edge of the baffle and over an exterior wall of the enclosure, and draining the water out of the channel into an exit location.
