Abstract
Official abstract text for this publication.
Electric horn devices for a vehicle and vehicles with the electric horns are provided. An electric horn device includes a housing that is tightly sealed, a housing section within the housing, and a membrane element within the housing and configured to generate a sound. An elastic pressure equalizing element is adapted to allow pressure equalization in the housing.
First claim
Opening claim text (preview).
What is claimed is: 1. An electric horn device for a vehicle, the electric horn device comprising: a housing that is tightly sealed; a housing section within the housing; a membrane element within the housing and configured to generate a sound, and an elastic pressure equalizing element coupled to a portion of the housing section and elastically deformable relative to the housing section to allow pressure equalization in the housing. 2. The horn device according to claim 1 , wherein the elastic pressure equalizing element is an elastic bellows. 3. The horn device according to claim 1 , wherein the elastic pressure equalizing element is an elastic balloon. 4. The horn device according to claim 1 , wherein the elastic pressure equalizing element is an elastic membrane. 5. The horn device according to claim 1 wherein the elastic pressure equalizing element comprises an elastic material. 6. The horn device according to claim 5 , wherein the elastic pressure equalizing element comprises an elastomer. 7. The horn device according to claim 1 , wherein the housing section and/or membrane element comprise a corrosion-resistant material. 8. The horn device according to claim 1 , wherein the housing section has an electric coil and first magnetic core element that is partially accommodated in the electric coil, and wherein the membrane element has a second magnetic core element that dips at least partially into the electric coil. 9. The horn device according to claim 1 , further comprising an electrical terminal that is tightly joined with the housing section. 10. The horn device according to claim 1 , wherein the housing is configured without a pressure equalizing or vent opening. 11. The horn device according to claim 1 , wherein the vehicle is a motor vehicle. 12. The horn device according to claim 1 , wherein the elastic pressure equalizing element is coupled to the housing section of the housing in such a way as to seal the housing. 13. A vehicle with an electric horn device comprising: a housing that is tightly sealed; a housing section within the housing; a membrane element within the housing and configured to generate a sound, and an elastic pressure equalizing element coupled to a portion of the housing section and elastically deformable relative to the housing section to allow pressure equalization in the housing. 14. The vehicle according to claim 13 wherein the vehicle is a motor vehicle. 15. The vehicle according to claim 13 , wherein the elastic pressure equalizing element is an elastic bellows, an elastic balloon, or an elastic membrane. 16. The vehicle according to claim 13 , wherein the elastic pressure equalizing element comprises an elastic material. 17. The vehicle according to claim 13 , wherein the housing section and/or the membrane element comprises a corrosion-resistant material. 18. The vehicle according to claim 13 , wherein the housing section has an electric coil and first magnetic core element that is partially accommodated in the electric coil, and wherein the membrane element has a second magnetic core element that dips at least partially into the electric coil.
