Loudspeakers and related components and methods
A loudspeaker includes an acoustic enclosure, and an electro-acoustic transducer that is supported by the acoustic enclosure. A grille covers the electro-acoustic transducer, and a weather-resistant member is disposed between the acoustic enclosure and the grille. A spring member is disposed between the weather-resistant member and the acoustic enclosure. The spring member is configured to apply a force to the weather-resistant layer thereby to hold the weather-resistant member against the grille.
1. A loudspeaker comprising: an acoustic enclosure;
an electro-acoustic transducer supported by the acoustic enclosure; a grille covering the electro-acoustic transducer;
a weather-resistant member disposed between the acoustic enclosure and the grille; and
a spring member disposed between the weather-resistant member and the acoustic enclosure,
wherein the spring member is configured to apply a force to the weather-resistant member thereby to hold the weather-resistant member against the grille,
wherein the spring member comprises an arcuate main body that extends between a pair of opposing sidewalls.
2. The loudspeaker of claim 1 , wherein the weather-resistant member comprises a scrim layer.
3. The loudspeaker of claim 2 , wherein the scrim layer is formed of an acoustically transparent sheet form foam material.
4. The loudspeaker of claim 1 , wherein the arcuate main body is biased outwardly, away from the acoustic enclosure, such that a concave side of the main body faces toward the acoustic enclosure.
5. The loudspeaker of claim 4 , wherein the arcuate main body comprises a plurality of cross-members.
6. The loudspeaker of claim 5 , wherein the cross-members extend diagonally relative to the sidewalls.
7. The loudspeaker of claim 5 , wherein the cross-members intersect with each other at nodes.
8. The loudspeaker of claim 5 , wherein the cross-members are arranged to form a notch to accommodate the geometry of the electro-acoustic transducer.
9. The loudspeaker of claim 2 , wherein the weather-resistant member further comprises a screen layer disposed between the spring member and the scrim layer, wherein the spring member is configured to apply a force to the screen layer to hold a front surface of the screen layer against a rear surface of the scrim layer and to hold a front surface of the scrim layer against a rear surface of the grille.
10. The loudspeaker of claim 9 , wherein the screen layer comprises an acoustically transparent sheet form material formed of a woven fabric of metal filaments.
11. The loudspeaker of claim 1 , wherein the weather-resistant member comprises a screen layer.
12. The loudspeaker of claim 11 , wherein the screen layer comprises an acoustically transparent sheet form material formed of a woven fabric of metal filaments.
13. A grille assembly for a loudspeaker, the grille assembly comprising:
a grille;
a spring member; and
a weather-resistant member disposed between the spring member and the grille, wherein the spring member is configured to apply a force between an acoustic enclosure of a loudspeaker and the weather-resistant member to hold a front surface of the weather-resistant member substantially flush against a rear surface of the grille,
wherein the spring member comprises an arcuate main body that extends between a pair of opposing sidewalls.
14. The grille assembly of claim 13 , wherein the weather-resistant member comprises a scrim layer.
15. The grille assembly of claim 14 , wherein the scrim layer is formed of an acoustically transparent sheet form foam material.
16. The grille assembly of claim 13 , wherein the sidewalls terminate at a pair of feet, which are arranged to rest against a surface of the acoustic enclosure of the loudspeaker.
17. The loudspeaker of claim 13 , wherein the arcuate main body is biased outwardly, away from the acoustic enclosure, such that a concave side of the main body faces toward the acoustic enclosure.
18. The grille assembly of claim 13 , wherein the arcuate main body comprises a plurality of cross-members.
19. The grille assembly of claim 18 , wherein the cross-members extend diagonally relative to the sidewalls.
20. The grille assembly of claim 18 , wherein the cross-members intersect with each other at nodes.
21. The grille assembly of claim 18 , wherein the cross-members are arranged to form a notch to accommodate the geometry of an electro-acoustic transducer of the loudspeaker.
22. The grille assembly of claim 14 , wherein the weather-resistant member further comprises a screen layer disposed between the spring member and the scrim layer, wherein the spring member is configured to apply a force to the screen layer to hold a front surface of the screen layer against a rear surface of the scrim layer and to hold a front surface of the scrim layer against a rear surface of the grille.
23. The grille assembly of claim 22 , wherein the screen layer comprises an acoustically transparent sheet form material formed of a woven fabric of metal filaments.
24. The grille assembly of claim 13 , wherein the weather-resistant member comprises a screen layer.
25. The grille assembly of claim 24 , wherein the screen layer comprises an acoustically transparent sheet form material formed of a woven fabric of metal filaments.
