## Abstract

A waterproof adapter can provide a liquid-tight seal between a waterproof housing for a mobile electronic device and an accessory connector extending from an accessory device, such as a jack plug extending from a pair of headphones. The waterproof adapter can be an integral part of the accessory connector or can be installed on the accessory connector using, for example, a threaded or bayonet-style connection. In one example, the waterproof adapter can include an exterior gasket channel circumscribing an exterior surface of its body, an exterior gasket disposed at least partially within the exterior gasket channel, thereby permitting the waterproof adapter to provide a liquid-tight seal between a connector aperture in the waterproof housing and the accessory connector. When the accessory device is disconnected from the mobile electronic device, a port-sealing bung can be inserted into the connector aperture of the waterproof housing and can provide a liquid-tight seal therewith.

## Claims

### Claim 1

A waterproof adapter configured to provide a liquid-tight seal between a waterproof housing for a mobile electronic device and an accessory connector of an accessory device, the accessory connector having a jack plug gasket, the waterproof adapter comprising:
a body having an exterior surface, a hole passing through a centerline axis of the body, the hole defining an interior surface of the body, the body having a first attachment feature on the interior surface, the first attachment feature having at least one of a threaded feature and a bayonet-style mounting feature, the first attachment feature configured to attach to a second attachment feature on the accessory connector of the accessory device, the body having two or more tension tabs extending from a first end;
an exterior gasket disposed on the exterior surface of the body; and
an interior gasket seat proximate the interior surface of the body, the first attachment feature of the body and the second attachment feature on the accessory connector configured to form a liquid-tight seal between the jack plug gasket of the accessory connector and the interior gasket seat of the waterproof adapter.

### Claim 2

A waterproof adapter configured to provide a liquid-tight seal between a waterproof housing for a mobile electronic device and an accessory connector of an accessory device, the waterproof adapter comprising:
a body having an exterior surface, a hole passing through a centerline axis of the body, the hole defining an interior surface of the body, the body comprising a first attachment feature on the interior surface, the first attachment feature configured to attach to a second attachment feature on the accessory connector of the accessory device to form a liquid-tight seal between a jack plug gasket on the accessory connector and an interior gasket seat proximate the interior surface of the body, the body comprising at least one of a threaded feature and a bayonet mounting feature on the first attachment feature, the body comprising two or more tension tabs extending from a first end of the body;
an exterior gasket channel on the exterior surface of the body, the exterior gasket channel circumscribing the exterior surface of the body; and
an exterior gasket disposed at least partially within the exterior gasket channel.

### Claim 3

A waterproof adapter configured to provide a liquid-tight seal between a waterproof housing for a mobile electronic device and an accessory connector of an accessory device, the accessory connector having a lack plug gasket, the waterproof adapter comprising:
a body having:
an exterior surface,
a hole passing through a centerline axis of the body, the hole defining an interior surface of the body,
a first attachment feature on the interior surface of the body, the first attachment feature configured to attach to a second attachment feature of the accessory connector of the accessory device to form a liquid-tight seal between the jack plug gasket of the accessory connector of the accessory device and an interior gasket seat proximate the interior surface of the body,
at least one of a threaded feature and two or more bayonet-style mounting features on the interior surface of the body;
two or more tension tabs extending from a first end of the body, each tension tab comprising a lip portion that extends outwardly relative to the centerline axis of the body; and
an exterior gasket disposed on the exterior surface of the body.

### Claim 4 (depends on 3)

The waterproof adapter of claim 3, wherein each tension tab further comprises a receiving notch proximate each lip portion, each receiving notch configured to receive an aperture protrusion extending from an inner surface of a connector aperture of the waterproof housing for the mobile electronic device.

### Claim 5 (depends on 3)

The waterproof adapter of claim 3, each lip portion configured to associate with a lip receiving notch in a connection aperture of the waterproof housing.

### Claim 6

An accessory connector for an accessory device, the accessory connector configured to provide a liquid-tight seal when inserted into a connector aperture of a waterproof housing for a mobile electronic device, the accessory connector comprising:
a connector extending from a body of the accessory connector, the body configured to allow a user to grasp the accessory connector during insertion or removal of the connector into or from, respectively, a corresponding connector of a mobile electronic device; and
a waterproof adapter configured to provide a liquid-tight seal between the connector aperture of the waterproof housing and the accessory connector of the accessory device, the waterproof adapter comprising:
two or more tension tabs extending from a first end of the waterproof adapter; and
an exterior gasket on the exterior surface of the waterproof adapter.

### Claim 7 (depends on 6)

The accessory connector of claim 6, wherein the waterproof adapter is removably attached to the accessory connector.

### Claim 8 (depends on 6)

The accessory connector of claim 6, wherein the waterproof adapter is an integrally formed portion of the accessory connector.

### Claim 9 (depends on 6)

The accessory connector of claim 6, wherein the accessory connector is configured to transfer power or data to and/or from the mobile device electronic when the mobile electronic device is encased in the waterproof housing.

### Claim 10 (depends on 6)

The accessory connector of claim 6, each tension tab further comprising a lip portion that extends outwardly relative to a centerline axis of the body.

### Claim 11 (depends on 6)

The accessory connector of claim 6, further comprising an exterior gasket channel on an exterior surface of the waterproof adapter, the exterior gasket disposed at least partially within the exterior gasket channel.
