Automotive speaker enclosure
View Patent ↗A speaker enclosure mounted within an internal wall of a vehicle may employ first and second enclosure halves that are vibration welded together to define an enclosure or cavity between the halves. A first leg and a second leg protrude from a bottom of the second half. The legs may have strengthening ribs to govern leg deflection resistance and further each have a resilient s-shaped tab protruding from the distal end of each leg to contact the wall of the vehicle. A first and a second fastener leg may each define a fastener hole and accept a fastener to help secure the speaker enclosure along with the first and second resilient legs. The fastener legs each may protrude from an enclosure half.
1. A speaker enclosure comprising:
a first half;
a second half joined to the first half thereby defining a cavity between the halves;
a first leg and a second leg protruding from the second half; and
an s-shaped mounting tab extending from a distal end of each of the first and second legs, the s-shaped mounting tab being elastically resilient and formed with the first and second legs;
wherein the s-shaped mounting tab is adapted to engage a structure at a free end thereof, whereby the s-shaped tab is arranged to elastically flex so as to have a first portion in compression and a second portion in tension.
2. The speaker enclosure of claim 1 , wherein the first and second legs are biasable such that a first portion can undergo tension and a second portion can undergo compression in response to dynamic loading.
3. The speaker enclosure of claim 1 , wherein the first and second legs each further comprise strengthening ribs to resist bending.
4. The speaker enclosure of claim 1 , wherein the second half further comprises a first and a second fastener tab.
5. A speaker enclosure comprising:
a first half;
a second half welded to the first half thereby defining a cavity between the halves;
a first leg and a second leg protruding from a bottom of the second half; and
an s-shaped mounting tab extending from a distal end of each of the first and second legs, the s-shaped mounting tab being elastically resilient and formed with the first and second legs;
wherein the s-shaped mounting tab is adapted to engage a structure at a free end thereof, whereby the s-shaped tab is arranged to elastically flex so as to have a first portion in compression and a second portion in tension.
6. The speaker enclosure of claim 5 , wherein the first and second legs each further comprise ribs to resist bending.
7. The speaker enclosure of claim 5 , wherein the first and second legs are biasable such that a first portion can undergo tension and a second portion can undergo compression in response to dynamic loading.
8. The speaker enclosure of claim 5 , wherein the second half further comprises a first and a second fastener leg.
9. The speaker enclosure of claim 8 , wherein the first and second fastener legs protrude from the second half.
10. The speaker enclosure of claim 9 , wherein the first and second fastener legs each define a hole for a fastener.
11. A speaker enclosure for a vehicle wall, comprising:
a first half;
a second half welded to the first half thereby defining a cavity between the halves; and
a first leg and a second leg protruding from a bottom of the second half, the first and second legs each including strengthening ribs arranged to resist bending, and first and second resilient s-shaped mounting tabs protruding from respective distal ends of the first and second legs;
wherein the s-shaped mounting tabs are arranged to engage the vehicle wall at a free end thereof, whereby the s-shaped mounting tabs are arranged to elastically flex so as to have a first portion in compression and a second portion in tension thereby providing a spring force against the wall.
12. The speaker enclosure of claim 11 , wherein the first and second legs are biasable such that a first portion can undergo tension and a second portion can undergo compression in response to dynamic loading.
13. The speaker enclosure of claim 12 , wherein the second half further comprises a first and a second fastener leg.
14. The speaker enclosure of claim 13 , wherein at least one of the first and second fastener legs are located on a side of the speaker enclosure opposite the first and second legs.
15. The speaker enclosure of claim 14 , wherein the first and second fastener legs each define a hole for a fastener.
16. The speaker enclosure of claim 14 , wherein the at least one of the first and second fastener legs cooperates with the first and second legs to impart a normal force against the vehicle wall to prevent movement of the speaker enclosure relative to the wall.
17. The speaker enclosure of claim 11 , wherein the s-shaped mounting tabs are arranged to be received through respective slots in the vehicle wall such that a curved portion of the s-shaped mounting tabs engage an inner side of the vehicle wall opposite the side of insertion of the s-shaped mounting tab.
