Suspension assembly for hearing aid receiver
View Patent ↗A suspension assembly for a hearing aid receiver is described in which the receiver is contained within a receiver can. A cover assembly may be provided for covering the open top end of the receiver can and for containing the receiver's spout when the receiver is mounted within the receiver can. To dampen or reduce the transmission of receiver vibrations within the receiver can, a spout seal and corner bumpers may also be provided.
1. A hearing aid, comprising:
a receiver for converting an electrical signal into an audio output;
a receiver can for containing the receiver, wherein the receiver can has top and bottom ends with the top end being open;
a spout at the top end of the receiver for conducting sound out of the receiver;
a cover assembly for covering the open top end of the receiver can and for containing the receiver's spout when the receiver is mounted within the receiver can;
wherein the cover assembly is mated to an audio tube for conducting sound from the receiver's spout; and,
a spout suspension seal that surrounds the spout within the cover assembly and that has a wrap-around tip extending over the end of the spout.
2. The hearing aid of claim 1 further comprising a spout suspension seal surrounding the receiver's spout within the cover assembly.
3. The hearing aid of claim 2 wherein the spout suspension seal is an annular ring made of elastic material that radially seals a connection between the receiver's spout and the audio tube.
4. The hearing aid of claim 1 further comprising elastomeric bumpers mounted on the bottom end of the receiver to suspend the receiver within the receiver can when the receiver is mounted therein.
5. The hearing aid of claim 4 wherein the receiver can and receiver are both generally cuboidal in shape and wherein a pair of elastomeric bumpers are mounted at opposite diagonal corners of the bottom end of the receiver.
6. The hearing aid of claim 1 further comprising corner braces attached to opposite bottom corners of the receiver.
7. The hearing aid of claim 6 wherein the corner braces are bonded in place.
8. The hearing aid of claim 6 wherein the corner braces are laser welded in place.
9. The hearing aid of claim 6 wherein the corner braces are over-molded with elastomer corner bumpers.
10. The hearing aid of claim 1 wherein the receiver can is disposed within a hearing aid housing.
11. A method for constructing hearing aid, comprising:
suspending a receiver for converting an electrical signal into an audio output in a receiver can, wherein the receiver can has top and bottom ends with the top end being open;
disposing a spout at the top end of the receiver for conducting sound out of the receiver;
placing a cover assembly for covering the open top end of the receiver can and for containing the receiver's spout when the receiver is mounted within the receiver can; and,
disposing a spout suspension seal surrounding the spout within the cover assembly, the spout suspension seal having a wrap-around tip extending over the end of the spout
mating the cover assembly to an audio tube for conducting sound from the receiver's spout.
12. The method of claim 1 further comprising placing a spout suspension seal to surround the receiver's spout within the cover assembly.
13. The method of claim 12 wherein the spout suspension seal is an annular ring made of elastic material that radially seals a connection between the receiver's spout and the audio tube.
14. The method of claim 11 further comprising mounting elastomeric bumpers on the bottom end of the receiver to suspend the receiver within the receiver can when the receiver is mounted therein.
15. The method of claim 14 wherein the receiver can and receiver are both generally cuboidal in shape and further comprising mounting a pair of elastomeric bumpers at opposite diagonal corners of the bottom end of the receiver.
16. The method of claim 11 further comprising attaching corner braces to opposite bottom corners of the receiver.
17. The method of claim 16 wherein the corner braces are bonded in place.
18. The method of claim 16 wherein the corner braces are laser welded in place.
19. The method of claim 16 further comprising over-molding the corner braces with elastomer corner bumpers.
20. The method of claim 11 further comprising disposing the receiver can within a hearing aid housing.
