HEARING ASSISTANCE DEVICE WITH LOW PROFILE OFFSET SPOUT

摘要

Disclosed herein, among other things, are methods and apparatuses for hearing assistance low profile offset spouts. One aspect of the present subject matter relates to a hearing assistance spout consisting of a one-piece spout with a curved path to an off-axis (e.g., offset) port. The spout may be manufactured using metal injection molding to provide for a reflow solder attachment to the hearing assistance microphone. One aspect of the present subject matter relates to placing a full-sized spout off-axis while maintaining an open state that does not restrict the acoustic path, which may allow the offset spout to include a radial seal independent of the microphone body itself. One aspect of the present subject matter relates to an offset spout including a sealed acoustic barrier wall to protect the acoustic inlet of the microphone from debris or moisture.

主权项

1. A low-profile hearing assistance spout device for a hearing assistance device including a microphone having an acoustic microphone port, the spout device comprising:
a planar portion in acoustic communication with a spout portion, the planar portion configured to mount adjacent the microphone with a surface forming an opening in alignment with the acoustic microphone port of a hearing assistance device; and a spout portion connected to the planar portion, the spout portion including an aperture for sound in acoustic communication with the acoustic microphone port to provide an acoustic pathway for sound received by the spout portion to reach the microphone, the spout portion connected at a non-normal angle to the planar portion to reduce ingress of unwanted materials that may reach the microphone.
