SHOCK RESISTANT RECEIVER AND METHOD OF MANUFACTURING THE SAME

摘要

An acoustic apparatus includes an outer housing, a receiver, and a shock cushion. The receiver is disposed within the outer housing. A plurality of viscoelastic members is disposed at least partially between the outer housing and the receiver. The plurality of viscoelastic members are sufficient to dampen mechanical energy received at the outer housing before reaching the receiver housing.

主权项

1. An acoustic apparatus comprising:
an outer housing having a longitudinal axis, the outer housing being configured to fit within an ear canal of a human user, the outer housing having a plurality of openings extending there through and the openings being spaced about the longitudinal axis; a receiver disposed within the outer housing, wherein the receiver is attached to the outer housing via a plurality of viscoelastic members; and a gap between the receiver and the outer housing; wherein the plurality of viscoelastic members are disposed at least partially between the outer housing and the receiver and wherein the plurality of viscoelastic members are constructed of a viscoelastic material that fills the openings and extends across the gap to contact the receiver, the members being configured to hold the receiver in place with respect to the outer housing during use of the acoustic apparatus.
