FIG. 2 shows a partial cross-sectional view of a BTE hearing aid with a base for mounting a circuit board assembly according to an embodiment. The hearing aid 200 includes a hearing aid housing 202, a circuit board assembly 204, and a base 212. The hearing aid housing includes receiving portion 234. The circuit board assembly 204 includes a circuit board 206, upward-facing components 208, and downward-facing components 210. In some embodiments, the circuit board 206 is a printed circuit board. In some embodiments, the circuit board assembly 204 includes only upward-facing components 208 or downward-facing components 210.
The base 212 is made of elastomeric material. Examples of elastomeric material include, but are not limited to, natural rubber, synthetic rubber, and thermoplastic elastomers. In some embodiments, the base 212 is made of silicone rubber. The base includes a cored region 214, support ribs 216, 218, 220, and 222, and overlap seal 232.
The support ribs 216, 218, 220, and 222 may have a height equal or greater than a maximum protrusion from the circuit board assembly 204 towards the cored region of a component mounted on the circuit board assembly 204. For example, support ribs 216 and 218 may have a height equal or greater than a tallest component 224 of the downward-facing components 210.
In some embodiments, support ribs may be of differing heights and widths. For example, support ribs 216 and 218 may be of a height greater than the tallest component 224 and support ribs 220 and 222 may be height equal to the tallest component 224. In some embodiments, support ribs may be a singular rectangular, circular, or other shaped rib of equal height and width.
In some embodiments, the cored region 214 is defined by the support ribs 216, 218, 220, and 222. In some embodiments, the cored region 214 is as wide as the edges of the widest set downward-facing components 210. For example, the cored region 214 may be as wide as the distance between the extreme left edge of component 226 and the extreme right edge of component 224. In other embodiments, the cored region 214 is as wide as circuit board 206. For example, the cored region 214 may be as wide as the distance between the extreme left wall 228 and the extreme right wall 230 of the circuit board 206. Similarly, the cored region 214 may be as long as the longest set downward-facing components 210 or be as long as the circuit board 206.
Thus, the cored region 214 may correspond to the area around the edge of the circuit board assembly 204 that is unpopulated, e.g., an area that contains no components. The cored region 214 may also correspond to the area of the circuit board 206, or a combination of the area of the circuit board 206 and the edge of the circuit board assembly that is unpopulated. For example, the width of the cored region 214 may equal the width of the circuit board 206 and the length of the cored region 214 may equal the edge of the circuit board assembly 204 that is unpopulated.
The cored region 214, being made of elastomeric material, acts as a cushion to provide stability during drops and shocks- administered to the hearing aid 200. In addition, because the cored region 214 accepts downward-facing components in at least a portion of its depth, a low profile is possible as below seen in FIG. 3.
Moreover, because the base 212 is comprised of elastomeric material, circuit board assembly 204 may be incorporated into features where flexibility is desired. For example, a pushbutton operation may incorporate base 212 and circuit board assembly 204 in operating a feature of BTE headphone 200.
FIG. 3 shows a partial cross-sectional view of a BTE hearing aid with a base for mounting a circuit board assembly according to an embodiment. The hearing aid 300 includes a hearing aid housing 302 and a circuit board assembly 304 supported by a base 306. In some embodiments, a circuit board 305 is a printed circuit board. Upward-facing components 308 and downward-facing components 310 are mounted on the circuit board 305.
A base 306 includes a cored region 311, support ribs 312 and 314. In comparison to the profile 112 of FIG. 1, profile 316 is shallower because circuit board assembly 304 is mounted considerably closer to hearing aid housing 302 than the respective circuit board assembly 104 in FIG. 1. A lower profile, among other things, reduces overall size for a BTE hearing aid and increases comfort when worn by users.
FIG. 4 shows a top view of a base for mounting a circuit board assembly according to an embodiment. A base 400 includes support ribs 402, 404, 406, and 408, a cored region 410, and an overlap seal 412. In this embodiment, support ribs 404 and 408 equal the height maximum height of a component protrusion from a bottom surface of a circuit board assembly towards the cored region 410. Support ribs 404 and 408 define the length of the cored region 410, wherein the cored region 410 is as long as the longest set downward- facing components of a circuit board assembly. Support ribs 402 and 406 are of a height greater than the height maximum height of a component protrusion from a bottom surface of a circuit board assembly towards the cored region 410. Support ribs 402 and 406 partially define the width of the cored region 410, wherein the cored region 410 has a width substantially equal to a circuit board.
FIG. 5 shows a bottom view of a base for mounting a circuit board assembly according to an embodiment. A base 500 includes support ribs 502 and 506, a cored region 510, and an overlap seal 512. The overlap seal 512 is configured to physically couple with a receiving portion of a hearing aid housing and thus may take on a large variety of shapes and sizes. For example, the overlap seal 512 may be circular and/or may be composed of one or more ribs. In FIG. 5, overlap seal 512 is a rectangular rib. In some embodiments, a base may comprise a flat bottom surface and be mounted via a snug fit between the perimeter walls of the base 500 and a receiving portion of a hearing aid housing or, for example, an adhesive such as liquid or gel adhesive, epoxy, or a polymer functioning as an adhesive.
FIG. 6 shows cross sectional view of a base for mounting a circuit board assembly according to an embodiment. Hearing aid 600 includes hearing aid housing 602. Hearing aid housing 602 includes receiving portion 604. The receiving portion 604 includes side walls 606 and 608. A base 610 physically couples with the receiving portion 604 by a portion of overlap seal 612 snugly sliding in between side walls 606 and 608. The seal formed by the overlap seal 612 and receiving portion 604 minimizes acoustic leakage from within the hearing aid housing 602 and prevents water or other liquids from entering the hearing aid housing 602. Grease such as silicone grease or similar greases may also be applied to the overlap seal 612 to further enhance acoustical and liquid sealing performance. FIGS. 7-9 show a sequence of installing a base for mounting a circuit board assembly in a BTE hearing aid according to an embodiment. In FIG. 7, a hearing aid 700 includes a hearing aid housing 702.

In FIG. 9, circuit board 706 is inserted between support ribs 714 and 716 and, at the same time, the downward-facing components 710 are inserted between support ribs 718 and 720. The support ribs 714, 716, 718, and 720 may have a height equal or greater than a maximum protrusion from the circuit board assembly 204 towards the cored region of a component mounted on the circuit board assembly 204.
In some embodiments, the cored region 722 is defined by the support ribs 714, 716, 718, and 720. In some embodiments, the cored region 722 is as wide as the edges of the widest set downward-facing components 710. In other embodiments, the cored region 722 is as wide as circuit board 706. Similarly, cored region 722 may be as long as the longest set downward-facing components of downward-facing components 710 or be as long as the circuit board 706.
In FIG. 10, a hearing aid 1000 includes a hearing aid housing 1002. The hearing aid housing 1002 includes a receiving portion 1028, which accommodates a base 1012.
