## Abstract

Examples of a removable earpiece assembly configured for coupling to a canal hearing device using a foil-thin clip are described. The earpiece assembly may be readily removed for replacement when soiled or degraded after use. The earpiece assembly may include a compliant element for contact with the ear canal in a comfortable and safe manner. The earpiece assembly may function as an acoustic seal and/or a retainer for the canal hearing device. The removable earpiece assembly may provide a highly space efficient solution which may be used with miniature canal hearing devices, including a CIC device. In some embodiments, disengagement of the earpiece assembly from the canal hearing device may be accomplished by a side peel motion.

### Claim 10 (depends on 1)

The seal assembly of claim 1, wherein the seal assembly is configured to be attached to the canal hearing device using a snap mechanism.

### Claim 11 (depends on 1)

The seal assembly of claim 1, wherein the seal assembly is configured to be disengaged from the canal hearing device using a tool.

### Claim 12 (depends on 1)

The seal assembly of claim 1, wherein the clip element is bonded to the compliant seal element.

### Claim 13 (depends on 12)

The seal assembly of claim 12, wherein the clip element is bonded to the compliant seal element at a joint of the clip element.

### Claim 14 (depends on 2)

The seal assembly of claim 2, wherein the one or more protruding features include one or more angled surfaces for releasable engagement with the one or more cut-outs.

### Claim 15 (depends on 1)

The seal assembly of claim 1, wherein the thickness of the metal foil is in the range of 0.05 to 0.08 mm.

### Claim 16 (depends on 1)

The seal assembly of claim 1, wherein the clip element is configured to disengage from the canal hearing device when a separating axial force of 2 lbs or more is applied between the canal hearing device and the clip element.

### Claim 17 (depends on 1)

The seal assembly of claim 1, wherein the clip element is configured to engage with the canal hearing device when a clip-on force of 0.5 lbs or less is applied between the canal hearing device and the clip element.

### Claim 18 (depends on 1)

The seal assembly of claim 1, wherein the seal assembly is configured to be removed from the canal hearing device by a side-peel motion.

### Claim 19 (depends on 1)

The seal assembly of claim 1, wherein the seal assembly is configured to be removed from the canal hearing device by an axial unsnap motion.

### Claim 20

An earpiece assembly for insertion into the ear canal, wherein the earpiece assembly is configured to be removably attached to a canal hearing device to securely retain the canal hearing device inside the ear canal, the earpiece assembly comprising:
a clip element formed of thin metal foil not exceeding 0.2 mm in thickness, wherein the clip element is configured to securely attach to a canal hearing device encapsulating a receiver assembly concentrically therewithin; and
a compliant element, at least partially concentrically positioned about the clip element, wherein the clip element is deformable when the earpiece assembly is detached from the canal hearing device.

### Claim 21 (depends on 20)

The earpiece assembly of claim 20, wherein the clip element comprises one or more locking tabs.

### Claim 22 (depends on 20)

The earpiece of claim 20, wherein the clip element comprises one or more cut-outs configured for cooperating fit with protruding features of the canal hearing device.

### Claim 23 (depends on 20)

The earpiece assembly of claim 20, wherein the compliant element is made of a biocompatible elastomer.

### Claim 24 (depends on 20)

The earpiece assembly of claim 20, wherein the earpiece assembly is attached to the canal hearing device using a snap mechanism.
