Title

Modular battery accessory for sound processor with internal battery

Abstract

Disclosed is a modular battery accessory that can be attached to a sound processor that usually operates using an internal battery.

Problem Addressed 

In a hearing aid context, a sound processor with an internal (non-removable) rechargeable battery has benefits but will eventually run out of charge. An external wired battery pack is inconvenient for the user. Radio frequency (RF) emissions requirements due to the use of a long cable also increase the size of the total system (i.e., sound processor plus battery pack).

State of technology

Traditional sound processors commonly have no internal battery and rely on a modular battery unit to function. The connector for this battery unit consumes significant volume in the sound processor and is a challenge to seal against ingress (e.g., of water).

Sound processors with an internal battery can have a limited battery life and require the use of a wired external battery pack to provide additional power to the sound processor when the internal battery is depleted. This wired external battery pack is too large to wear behind the ear, and therefore must be worn somewhere on the body (such as in a pocket). The battery pack and its long cable are inconvenient and are not discrete; however, the design is considered necessary and must be used for the recipient to remain “on air”.

Novelty Statement

The novel contribution is a modular battery accessory that can be attached to a sound processor that usually operates using an internal battery.

The industry trends towards making a sound processor as small as possible, this accessory effectively increases the size of the sound processor at least some of the time (when the accessory is used).

Description (Components, Process)

This accessory is fixed to the sound processor itself. The accessory can therefore sit behind the ear or otherwise in the immediate vicinity of the sound processor. This is particularly useful for sound processors that sit behind the ear but is also appli...
