A hearing device, such as a receiver-in-canal hearing aid, has a receiver unit with a receiver, and a control unit. The control unit is connected to the receiver unit via two activation lines to activate the receiver. In addition, a further component, such as a controllable ventilation element, is located in the receiver unit, and the further component is likewise activated via the activation lines by a control signal which is output by the control unit.

A vibroacoustic earbud (“earbud”) is proposed that includes a housing and an infrasonic/vibration sensor. The housing includes a nozzle with a nozzle tip that is configured for positioning within an ear canal of an individual. The sensor is included within the nozzle and detects biosignals including infrasonic signals from a body of the individual in the ear canal. The nozzle tip engages with a wall of the ear canal to provide an earbud seal, the result of which forms an ear canal acoustic volume that amplifies the biosignals. The earbud is tuned/designed to minimize loss of amplitude of the biosignals detected by the sensor in the ear canal acoustic volume when an unintentional leak occurs in the earbud seal that possibly reduces acoustic pressure in the ear canal acoustic volume.

Playback devices such as headphone devices can include an earpiece configured to be positioned adjacent a user's ear. The earpiece can include a transducer having a diaphragm configured to face toward the user's ear when the earpiece is positioned adjacent the user's ear, as well as an outlet vent in fluid communication with the transducer and a microphone. A support member within the earpiece includes a first opening aligned with the microphone and a second opening aligned with the outlet vent. An acoustic mesh extends over the first opening and the second opening, wherein the mesh has a substantially uniform acoustic impedance.

Herein described may be an embodiment of a surround sound headphone device for the production of surround sound which may comprise a first and second headphone assembly which may have acoustic chamber surrounds. The acoustic chamber surrounds may envelope a first and second acoustic chamber assembly. The first and second acoustic chamber assembly may have an acoustic chamber dividing partition, a one or more than one high frequency external port, a one or more than one low frequency external port, a one or more than one low frequency high frequency port, a one or more than one high frequency high frequency port, a one or more than one high frequency auditory source and, a one or more than one low frequency auditory source.

Embodiments describe an eartip including an eartip body having an attachment end and an interfacing end opposite from the attachment end, and including an inner eartip body and an outer eartip body. The inner eartip body has a sidewall that extends between the interfacing end and the attachment end, and includes a groove formed in an outer surface of the sidewall. The outer eartip body is sized and shaped to be inserted into an ear canal and extends from the interfacing end toward the attachment end of the eartip.

A hearing device includes a sound path component having: a chamber at a first end of the hearing device; a vent channel extending from the chamber to a second end of the hearing device, the vent channel having a first vent end at the chamber and a second vent end; an output transducer opening configured to couple to an output transducer; a first opening at the chamber and being configured to face towards an ear canal of the user; and a second opening at the second end of the hearing device and being configured to face towards a surrounding, the second opening being at the second vent end of the vent channel; and an input transducer opening configured to couple to a first input transducer; the vent channel, the input transducer opening, the output transducer opening, the first opening and the second opening being in fluid connection with each another.

An electroacoustic transducer includes a housing, one or more partition walls, a diaphragm, and a tube. The one or more partition walls divide an inner space of the housing into a plurality of spaces, such that a volume of a first of the plurality of spaces is different from a volume of a second of the plurality of spaces except the first of the plurality of spaces. The diaphragm is disposed in the housing, such that one surface thereof faces the plurality of spaces. The tube establishes communication between a sound wave emission opening that is open to an outer space of the housing and each of the plurality of spaces.

A hybrid ANC system that can allow a feedback microphone to receive the same external noise as a feedforward microphone. A processor can generate an anti-noise signal based on what both microphones received to cancel a broader range of frequencies of the external noise.

The present disclosure relates to dual-diaphragm moving-coil audio transducers for hearing devices. The transducer includes a magnetic circuit including an inner portion located between first and second coils coupled to corresponding diaphragms supported by a housing. An outer portion of the magnetic circuit is adjacent outer portions of the first and second coils. The transducer emits sound when the first diaphragm moves in a first direction and the second diaphragm moves in a second direction, opposite the first direction, in response to an electrical audio signal applied to the first and second coils.

In one embodiment, the present invention is directed to a contact hearing system comprising: an ear tip including a transmit coil, wherein the transmit coil is connected to an audio processor, including an H Bridge circuit; a first input to the H Bridge circuit comprising an AND circuit wherein a first input to the AND circuit comprises a carrier signal and a second input to the AND circuit comprises an output of a delta sigma modulation circuit, wherein the delta sigma modulation circuit is a component of the audio processor; and a second input to the H Bridge circuit comprising an NAND circuit wherein a first input to the NAND circuit comprises a carrier signal and a second input to the NAND circuit comprises an output of the delta sigma modulation circuit.
