First Claim
Patent Images
1. A hearing aid comprising:
- a flexible circuit board containing a battery permanently affixed thereto, the battery having a first surface comprising at least one air intake hole the first surface opposed to, and spaced away from, a surface of the flexible circuit board; and
a spacer between the surface of the battery and the surface of the flexible circuit board, the spacer having an opening extending through the spacer, such that the surface of the battery, the opposing surface of the flexible circuit board and the spacer form a substantially enclosed chamber, the at least one air intake hole on the first surface of the battery at least partially open to the enclosed chamber, the enclosed chamber having a vent through the flexible circuit board to permit air to enter the enclosed chamber, the cross-sectional area of the vent substantially less than the cross-sectional area of the air intake hole in the battery such that the vent restricts the flow of air to the air intake hole.

Abstract
A hearing aid includes a circuit board having a battery affixed thereon and a switch that utilizes a portion of the circuit board as a portion of the switch. The battery is permanently affixed to the circuit board in at least one location and at least a portion of the battery is spaced away from the circuit board. The circuit board further includes at least one pair of printed switch traces. The switch is integrated into the circuit board in a way that utilizes the circuit board to form a rotary switch.
