<p>A sound transmitting device configured to fit within an ear canal, such as a hearing aid or a monitor, for example, having first and second portions which are relatively movable with respect to each other. As a result of these relatively moving portions, the device can better accommodate changes in the shape and/or orientation of the ear canal. More particularly, after the device has been fitted into the ear canal, the first and second portions can move relative to each other and comply with a new shape and/or orientation of the ear canal. As a result, it is less likely that the device will impede the change in the ear canal thereby reducing potential discomfort to the user. To facilitate this relative movement, the first and second portions can include at least partially spherical surfaces which are configured to permit relative movement therebetween.</p> |
