## Title
Hearing aid removal handle

## Abstract

A removal handle design for a hearing aid is described in which the removal handle is attached to the battery door of the hearing aid. By locating the removal handle in the battery door, the removal handle may be added as the last step in the manufacturing process, thus ensuring no damage from cutting/beveling/buffing equipment. The design also eliminates interference with the opening and closing of the battery door.

## Background
FIELD OF THE INVENTION
This invention pertains to electronic hearing aids and methods for their construction.
BACKGROUND
Hearing aids are electronic instruments that compensate for hearing losses by amplifying sound. The electronic components of a hearing aid include a microphone for receiving ambient sound, an amplifier for amplifying the microphone signal in a manner that depends upon the frequency and amplitude of the microphone signal, a speaker for converting the amplified microphone signal to sound for the wearer, and a battery for powering the components. In certain types of hearing aids, the electronic components are enclosed by housing that is designed to be worn in the ear for both aesthetic and functional reasons. Such devices may be referred to as in-the-ear (ITE), in-the-canal (ITC), completely-in-the-canal (CIC) type, or invisible-in-the-canal (IIC) hearing aids. These types of hearing aids are typically equipped with a handle attached to the housing that enables the wearer to easily remove the hearing aid from the ear.



BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 shows the basic electronic components of an example hearing aid.
FIG. 2 shows a top view of the housing of an example hearing aid.
FIGS. 3 and 4 depict cross-sectional views of the housing shown in FIG. 2.



DETAILED DESCRIPTION
Current designs for hearing aid removal handles are subject to numerous problems. The handles may break, necessitating that the hearing aid be returned to the manufacturer for repair. In some cases a patient may even have to go to a doctor to have the hearing aid removed from the ear. Also, the position of the removal handle on the hearing aid may cause interference with the opening and closing of battery door. Removal handles are also typically attached directly to the faceplate of the hearing aid during the manufacturing process. Subsequent steps in the manufacturing process, such as cutting/beveling/buffing, may damage and weaken the removal handle.
As described below, theses problems may be ameliorated by a removal handle design in which the removal handle is attached to the battery door of the hearing aid. By locating the removal handle in the battery door, the removal handle may be added as the last step in the manufacturing process, thus ensuring no damage from cutting/beveling/buffing equipment. The design also eliminates interference with the opening and closing of the battery door. The removal handle may be easily changed in the field if needed by simply changing the battery door. Different length removal handles can be made to accommodate different patients.
FIG. 1 illustrates the basic functional components of an example hearing aid. The electronic circuitry of a typical hearing aid is contained within a housing that is commonly either placed in the external ear canal or behind the ear. A microphone or other input transducer 105 receives sound waves from the environment and converts the sound into an input signal. After amplification by pre-amplifier 112, the input signal is sampled and digitized by A/D converter 114 to result in a digitized input signal. The device's processing circuitry 100 processes the digitized input signal into an output signal in a manner that compensates for the patient's hearing deficit. The output signal is then passed to an audio amplifier 165 that drives an output transducer 160 or receiver for converting the output signal into an audio output. A battery 175 supplies power for the electronic components.
FIGS. 2 and 3 show a top view and a cross-sectional side view, respectively, of an example housing or enclosure 200 for a hearing aid. The cross-section of FIG. 3 is taken vertically through approximately the middle of FIG. 2. The enclosure is made up of an ear mold 205, within which are housed the electronic components the electronic components described above with reference to FIG. 1, and a faceplate 210. At the end of the ear mold opposite the faceplate is an outlet port 206 for the receiver to convey sound to the wearer's ear. The faceplate includes a status indicator light 215 and a microphone inlet port 220. Also hingedly mounted on the faceplate via hinge 240 is a battery door 250 that opens into a battery compartment 255 to allow replacement of the battery 175. The battery door may be seated underneath a portion of the faceplate via tabs or other extension to secure it in a closed position. An indentation on the faceplate may allow the user to pop the battery door open when access to the battery compartment is needed. Affixed to the battery door 250 is a removal handle 260 that is made up of an elongated portion 260a and a bulbous portion 260b at its end.
The elongated portion 260a of the removal handle may be a flexible structure such as a monofilament line. In the embodiment shown in FIG. 3, the elongated portion 260a is passed through a hole in the battery door and then attached to the underside of the battery door to secure it. In an alternative embodiment, illustrated by FIG. 4, the elongated portion 260a is double-looped through two additional holes and attached to the underside of the battery door. The battery door may be secured in a closed position by means of extensions or otherwise as discussed above to prevent opening of the door when the removal handle is pulled upon. As illustrated by the embodiments of both FIGS. 3 and 4, the removal handle may also be attached to the battery door nearer the hinge than to the opposite top end of the door and then angled toward the top end. Attaching the removal handle in this way further lessens the chance that the battery door will be opened when a pulling force is exerted on the removal handle.
