摘要:
A method and apparatus for removing heat from an acoustically shielded electro-mechanical assembly without relying upon a convective air flow and without the provision of bulky external heat sinks provides an acoustically shielded electro-mechanical assembly, such as a hard disk drive, that may be used in a personal computer. The invention may be used successfully in any application where noise mitigation measures, such as encapsulation of an electro-mechanical assembly within an acoustic shield, otherwise cause undesirable overheating of the assembly.

An embodiment provides a seal for retaining a hearing device within the ear canal comprising a curved shell having an opening at a shell apex portion. The shell defines a cavity for retention of a device component. An interior surface of a shell wall has a scalloped shape configured to distribute compressive forces applied to the shell perimeter such that when the shell is positioned in the canal, the shell wall conforms to the shape of the canal to maintain an acoustical seal between a shell exterior surface and the canal walls. The scalloped shape can be configured to produce a substantially constant amount of inward deformation of a shell wall independent of a force application point on a shell perimeter. The shell can include a coating to retain the seal in the canal and/or to promote asparagine growth into the coating to fastenly retain the seal in the canal.

A semi-permanent hearing device is disclosed which is adapted to be completely positioned within the ear canal of an individual for long-term use. The device comprises a sealing retainer substantially positioned in the bony region of the ear canal and a core assembly including a receiver assembly coaxially positioned within the sealing retainer. When the device is inserted into its completely-in-the-canal position, the core assembly extends from the sealing retainer to the cartilaginous region of the ear canal in a non-occluding fashion, thereby minimizing interference in the ear canal. The hearing device is inserted in the ear canal past the aperture thereof and in close proximity to the eardrum by a physician or a hearing aid dispenser.

A battery assembly is constructed of an elongated plastic shell irregularly shaped to fit optimally in anatomical cavities, particularly ear canals. The battery assembly relies structurally on a thin plastic shell which is designed to be inexpensively formed in a variety of complex shapes, thus offering superior volumetric utilization and energy capacity when compared with conventional metal button cell designs. In preferred embodiments, the shell is domed to distribute axial stresses so that it can be thin and still provide sufficient strength to avoid breakage in an extended wear environment despite its plastic composition. A preferred embodiment of a hearing device incorporating the battery assembly is disposable, to be discarded upon depletion of the electrical energy of the battery assembly.

The present invention provides an extremely space efficient battery enclosure and battery replacement methods for miniature hearing devices that are deeply and entirely positioned within the ear canal of an individual. The battery enclosure is a thin encapsulation that is formed or fitted directly over the battery thus substantially assuming the shape of the encapsulated battery. The battery enclosure, containing mostly the battery, is fitted concentrically within the narrow cavity of the ear canal with the long axis of the enclosure and the battery therein positioned along the long axis of the oval ear canal. In one embodiment of the invention, the enclosure is disposable and is elastically expandable to fit over the battery during its replacement. In another embodiment, the battery enclosure is coated over the battery with protruding contacts forming a battery assembly ready for electrical connection to a miniature canal hearing device.
摘要:
A device to be worn in the ear of a subject provides a direct vibrational drive to the tympanic membrane through a vibrationally conductive assembly which couples vibrations from a vibratory transducer positioned within the ear canal proximal to the tympanic membrane. In one embodiment of the invention, the device is a hearing aid positioned inconspicuously deep within the ear canal. The vibrationally conductive assembly is removably attached to the umbo area of the tympanic membrane. The vibrationally conductive assembly is designed to conduct vibrations in the audible frequency range while absorbing static forces caused by device placement and ear canal movement attributable to jaw movements of the wearer, including speaking, eating, drinking, chewing, yawning, and so forth. The unique coupling characteristics of the vibrationally conductive assembly allow for a highly efficient transfer of vibrations in the audible frequency range to the tympanic membrane without exerting damaging forces on the tympanic membrane. The energy efficiency and non-occlusive design features of a hearing aid embodiment of the invention allow for long term use within the ear canal.

A semi-permanent hearing device is disclosed which is adapted to be completely positioned within the ear canal of an individual for long-term use. The device comprises a sealing retainer substantially positioned in the bony region of the ear canal and a core assembly including a receiver assembly coaxially positioned within the sealing retainer. When the device is inserted into its completely-in-the-canal position, the core assembly extends from the sealing retainer to the cartilaginous region of the ear canal in a non-occluding fashion, thereby minimizing interference with hair and earwax production present in the cartilaginous region. In a preferred embodiment of the device, the core assembly comprises a battery assembly conforming substantially to the shape and dimensions of the battery enclosed within the assembly. A connector in the form of a thin ribbon film provides electrical and flexible mechanical connectivity between the receiver assembly, the centrally positioned battery assembly, and a microphone assembly positioned in the cartilaginous region. The disclosed hearing device is characterized by the absence of a unitary enclosure or a main housing, in contrast to the enclosure or housing which typically encompasses the battery along with other components in prior art hearing device designs.
摘要:
A disposable hearing device is adapted to be positioned entirely within an ear canal for extended wear therein. The device includes a core assembly and a sealing retainer. The core assembly includes a lateral section of generally oval cross-section and generally elongated cylindrical shape for alignment substantially along the ear canal's longitudinal axis, and a receiver section having a receiver coupled to the lateral section for medial positioning in the ear canal's bony region. The lateral section includes a microphone and a battery assembly, and is dimensioned to avoid occluding the ear canal while it is at least partially laterally suspended therein. The sealing retainer is concentrically positioned over the receiver section, and has a composition to conform to the ear canal's bony region wall to seat the hearing device and acoustically seal it in the ear canal to inhibit feedback therein.
