Abstract

A hearing instrument comprises: a microphone; a housing that defines an opening that leads to the microphone; a button disposed on the housing; and a ring member configured to be disposed within a recess defined in the housing and to define a perimeter around the button, wherein: the ring member defining an acoustic path that has a non-straight segment, the acoustic path has an external port and an internal port, and the internal port is configured to be aligned with the microphone opening of the housing.

First claim

What is claimed is:

1 . A hearing instrument comprising:
a microphone; a housing that defines an opening that leads to the microphone; a button disposed on the housing; and a ring member configured to be disposed within a recess defined in the housing and to define a perimeter around the button, wherein:
the ring member defines an acoustic path that has a non-straight segment,
the acoustic path has an external port and an internal port,
the acoustic path is configured to conduct sound from the external port to the internal port, and
the internal port is configured to be aligned with the opening that leads to the microphone.

2 . The hearing instrument of claim 1 , further comprising a button cover disposed on the hearing instrument to cover the button and the ring member, wherein the button cover defines one or more openings corresponding to the external port of the acoustic path.

3 . The hearing instrument of claim 2 , wherein the button cover comprises a mesh that defines the one or more openings.

4 . The hearing instrument of claim 2 , further comprising a basket removably disposed in one of the openings defined in the button cover, the basket defining one or more additional openings.

5 . The hearing instrument of claim 2 , wherein dimensions of the acoustic path remain consistent regardless of whether the button cover is in a depressed state.

6 . The hearing instrument of claim 2 , wherein the button cover is removable to allow cleaning of the acoustic path.

7 . The hearing instrument of claim 1 , wherein the non-straight segment is in a plane substantially orthogonal to a direction for depressing the button.

8 . The hearing instrument of claim 1 , wherein the ring member defines an alignment slot configured to engage an alignment ridge of the housing so as to prevent rotation of the ring member within the recess defined by the housing.
