The units are mechanically connected to each other to prevent twisting, and to the neck loop so that one of the units is on the left side of the chest, and the other electromechanical unit is on the right side of the chest.

A personal acoustic system and flexible mount for the same are disclosed. The flexible mount is comprised of an elastomeric material. The personal acoustic system further includes a band comprising a first mount and an earpiece comprising a second mount. An acoustic element is housed within the earpiece. The elastomeric mount is positioned intermediate the first mount and the second mount to flexibly connect the band to the earpiece.

Headphones, with one or two earcups (10), wherein each earcup (10) includes an electroacoustic sound generator (12) having a membrane (13) configured to radiate sound; a rear wall (14), wherein the membrane is arranged between the rear wall (14) and the user’s ear when the headphones are used, wherein a rear side of the membrane (13) faces a rear volume (26) between the membrane (13) and the rear wall (14) and a front side of the membrane (13) faces a front volume (20) between the membrane (13) and the user’s ear; and a tube (18) having a first and a second opening and an inner volume, wherein the tube (18) is arranged between the membrane (13) and the rear wall (14), and wherein the first opening of the tube (18) faces the membrane (13) and the second opening of the tube faces a peripheral environment behind the rear wall (14).

A modular headphone system that can afford the wearer configurable choices of hearing protection and quality sound delivery for music and programming is provided. In an embodiment, a modular headphone includes a headband and an earpiece mounted to the headband. The earpiece comprises a can comprising a speaker, the can secured to the headband. A removable and replaceable music ear cup is removably mountable to the can to overlie the speaker. A removable and replaceable hearing protection/sound amplification (HP/amp) ear cup is removably mountable to the can to overlie the speaker.

The present disclosure discloses an acoustic output apparatus including at least one acoustic driver, a controller, and a supporting structure. The at least one acoustic driver may be configured to output sounds through at least two sound guiding holes. The at least two sound guiding holes may include a first sound guiding hole and a second sound guiding hole. The controller may be configured to control a phase and an amplitude of the sounds generated by the at least one acoustic driver using a control signal such that the sounds output by the at least one acoustic driver through the first and second sound guiding holes have opposite phases. The supporting structure may be provided with a baffle and configured to support the at least one acoustic driver such that the first and second sound guiding holes are located on both sides of the baffle.

A headphone includes: a housing; a first driver unit disposed in the housing; a partition wall dividing an internal space of the housing into a first space and a second space, the first space containing the first driver unit; a second driver unit attached to the partition wall; and an acoustic adjustment circuit configured to receive a first signal to be input to the first driver unit and generate a second signal to be input to the second driver unit based on the first signal.

Adjustable auricular nerve stimulation devices, and associated systems and methods, are disclosed herein. A representative device for delivering an electrical signal to a subject includes a signal delivery element including at least two electrodes configured to deliver the electrical signal to a first portion of the subject’s ear. The device also includes a retention element configured to engage a second portion of the subject’s ear. The device further includes an adjustment mechanism permitting movement of the signal delivery element relative to the retention element to place the at least two electrodes in contact with the first portion of the subject’s ear.

The present disclosure provides an acoustic device including a microphone array, a processor, and at least one speaker. The microphone array may be configured to acquire an environmental noise. The processor may be configured to estimate a sound field at a target spatial position using the microphone array. The target spatial position may be closer to an ear canal of a user than each microphone in the microphone array. The processor may be configured to generate a noise reduction signal based on the environmental noise and the sound field estimation of the target spatial position. The at least one speaker may be configured to output a target signal based on the noise reduction signal. The target signal may be used to reduce the environmental noise. The microphone array may be arranged in a target area to minimize an interference signal from the at least one speaker to the microphone array.

A hearing protection device is presented. The device has a first earmuff connected to a second earmuff by a connector. Each of the first and second earmuffs are configured to receive an ambient sound and provide a dampened ambient sound to a wearer. The device also has a cable, with a cable length, that extends from the first earmuff to the second earmuff. The cable is coupled to the connector by a connection assembly. The connection assembly comprises a plurality of connection mechanisms arranged in a connection plan. Such a hearing protection device gives more freedom of placing the cable in a compact arrangement.

The embodiments of the present disclosure disclose an acoustic apparatus. The acoustic apparatus may include a support assembly. The support assembly may include a first portion and a second portion. When a user is wearing the acoustic apparatus, the first portion may be hung between a first side of an ear and a head of the user, the second portion may contact a second side of the ear. The first portion may cause the second portion to provide a compressive force on the second side of the ear.
