Abstract
Hearing devices configured to fit within the bony portion of the ear canal and batteries that may be used with same.
Claims75
A hearing device, comprising:
- a hearing device core including
- a battery, and
- an acoustic assembly including a microphone defining a medial end and a lateral end and a receiver defining a medial end and a lateral end, the microphone and receiver being positioned such that the lateral end of the receiver substantially abuts the medial end of the microphone,
- the battery and acoustic assembly being arranged such that one of the battery and acoustic assembly is superior to the other of the battery and acoustic assembly;
- and
- a seal apparatus on the hearing device core.
3 more elements
A hearing device, comprising:
- a hearing device core defining a medial end and a lateral end and including
- encapsulant,
- a microphone, a receiver and circuitry located within the encapsulant, and
- a battery,
- the encapsulant and at least a portion of the battery defining the exterior surface of the hearing device core between the medial and lateral ends of the hearing device core;
- and
- a seal apparatus on the hearing device core.
4 more elements
A hearing device, comprising:
- a hearing device core defining a medial end and a lateral end and including
- encapsulant,
- a microphone, a receiver and circuitry located within the encapsulant, and
- a battery located within the encapsulant,
- the encapsulant defining the exterior surface of the hearing device core between the medial and lateral ends of the hearing device core;
- and
- a seal apparatus on the hearing device core.
4 more elements
A hearing device, comprising
- a hearing device core including a microphone, a receiver, circuitry, and a battery, and defining a medial-lateral axis length of about 10-12 mm, a minor axis length of 3.75 mm or less, and a major axis dimension of 6.35 mm or less;
- and
- a seal apparatus on the hearing device core.
A hearing device for use in an ear including a tympanic membrane, an ear canal bony region, an ear canal cartilaginous region, and bony-cartilaginous junction, the hearing device comprising:
- a hearing device core defining a size and a shape, and including an acoustic assembly, with a microphone and a receiver with a sound port, and a battery;
- and
- a flexible seal apparatus on the hearing device core;
- wherein the size, shape and configuration of the hearing device core, and the flexibility of the seal, are such that the hearing device is positionable within the ear canal bony region with the entire microphone medial of the bony-cartilaginous junction and the receiver sound port either communicating directly with an air volume between the hearing device and the tympanic membrane or communicating with the air volume through a short sound tube.
1 more element
A hearing device, comprising:
- a hearing device core including
- a battery,
- an acoustic assembly with a microphone and a receiver,
- a magnetically actuated switch associated with the acoustic assembly, and
- a magnetic shield positioned between the battery and the magnetically actuated switch;
- and
- a seal apparatus on the hearing device core.
4 more elements
A hearing device, comprising:
- a hearing device core including a microphone, a receiver, circuitry, and a battery, and defining a medial-lateral axis dimension (DML), a superior-inferior dimension (DSI), and an anterior-posterior dimension (DAP), where DAP/DML≦0.38 and DSI/DML≦0.64 when DML=10-12 mm;
- and
- a seal apparatus on the hearing device core.
A battery can, comprising:
- a cathode portion;
- and
- an anode portion including an inwardly contoured region that defines an external retention ledge.
A battery, comprising:
- a battery can anode portion including an inwardly contoured region that defines an external retention ledge;
- anode material within the battery can anode portion;
- a battery can cathode portion;
- and
- a cathode assembly within the battery can cathode portion.
2 more elements
A method of assembling a battery, comprising the steps of:
- supporting a non-crimped anode can, including an anode portion, a cathode portion and an external retention ledge, by positioning a support under the external retention ledge;
- and
- crimping the cathode portion.
A method of making a battery can, comprising the step of:
- coating a sacrificial mandrel in the shape of the battery can interior with battery can material.
A battery can, comprising:
- a cathode portion defining a first cross-sectional area;
- an anode portion defining a second cross-sectional area;
- and
- a neck portion defining a third cross-sectional area that is less than the first and second cross-sectional areas, and which defines a longitudinally extending external gap, at the intersection between the cathode portion and the anode portion.
