A flexible arm that is configured to be located between and physically and electrically connect an acoustic module of an open-ear headphone to a battery housing of the open-ear headphone. The flexible arm defines an original resting length and position between the acoustic module and the battery housing. The flexible arm includes a flexible printed circuit that extends through the entire original resting length of the flexible arm and comprises a conductor that is configured to carry electrical energy between the acoustic module and the battery housing. A first interface structure is coupled to one of the acoustic module and the battery housing. A flexible material encases at least some of the flexible printed circuit and at least some of the first interface structure.

An acoustic device that is adapted to be worn on the body of a user, with a first acoustic transducer and a second acoustic transducer, where the first transducer is closer to the expected location of a first ear of the user than is the second transducer, a third acoustic transducer and a fourth acoustic transducer, where the third transducer is closer to the expected location of a second ear of the user than is the fourth transducer, and a controller that is adapted to independently control the phase and frequency response of the first, second, third and fourth transducers.

Embodiments relate to an audio system configured to provide enhancement of low audio frequencies. The audio system includes a tissue transducer and a speaker coupled to the tissue transducer. The tissue transducer is configured to be coupled to a tissue of a user (e.g., pinna of a user's ear). The speaker includes a diaphragm having a first surface and a second surface that is opposite the first surface. The first surface is configured to generate a first set of airborne acoustic pressure waves, and the second surface is configured to generate a backpressure. The tissue transducer is driven by the backpressure to vibrate the tissue to form a second set of acoustic pressure waves. The first set of airborne acoustic pressure waves and the second set of acoustic pressure waves together form audio content that is presented to the user.

The present disclosure provides an acoustic apparatus. The acoustic apparatus may include a hook-shaped part, a connecting part, and a holding part. When a user is wearing the acoustic apparatus, the hook-shaped part may be hung between a first side of an ear and a head of the user, the holding part may be in contact with a second side of the ear, and the connecting part may be connected with the hook-shaped part and the holding part. The hook-shaped part may include a first portion and a second portion, the first portion may be connected with the connecting part, and the second portion may be connected with the first portion. A projection of the first portion on a sagittal plane of the user may include a first curve. A projection of the second portion on the sagittal plane of the user may include a second curve.

A wireless earphone comprising a housing that defines an interior cavity having an inner surface and an outer surface; an opening extending through the housing from the inner surface to the outer surface; and a mesh assembly disposed over the opening and comprising a permanent assembly coupled to the housing and a replaceable assembly removably coupled to the permanent assembly and comprising a mesh.

A hearing aid assembly comprising a receiver comprising a front chamber and a back chamber being acoustically coupled to respective front and back chamber openings, and acoustical guiding means for guiding air from at least one of the front and back chamber openings to an air mixing zone for mixing air from the front and back chamber openings. The mixing of air from the front and back chambers enhances the low-frequency response of the hearing aid assembly.

The present invention discloses an earphone cover and an earphone assembly. The earphone cover having a through hole running axially through thereof. The earphone cover comprises a first attachment end, a second attachment end, a support portion, and a space defined by the support portion. The first and second attachment ends are positioned at each end of the through hole respectively. The support portion is set between the first and second attachment ends. The space is configured between an inner surface of the support portion and an outer surface of the earphone. The support portion deforms and air in the space escapes via the first and/or the second attachment ends under compression, and the support portion recovers to an original shape when the compression is removed.

Disclosed herein are an earset capable of correcting voice coming out at a user's ear using voice coming out of the user's mouth and a method of controlling the same.

An earset system according to an embodiment includes an earset having a first microphone and a first earphone inserted into the user's ear; and a controller configured to correct, based on a correction value, a first voice signal acquired through the first microphone using a reference voice signal coming out of the user's mouth when voice coming out at the user's ear is input into the first microphone.

A dome for a personal audio device. The dome forms a first flexible circumferential member and comprising a guiding structure extending in a longitudinal direction and forming an interface for guiding sound from or to the personal audio device. The guiding structure comprises a least one sound opening configured for passage of sound from or to the personal audio device in a direction transverse to the longitudinal direction of the guiding structure. The first flexible member is configured to at least partly close the sound opening during insertion of the dome into an ear canal of a user.

The present disclosure discloses a loudspeaker apparatus. The loudspeaker apparatus may include an ear hook including a first plug end and a second plug end, a core housing for accommodating an earphone core, and a circuit housing for accommodating a control circuit or a battery. The ear hook may be surrounded by a protective sleeve which is made of an elastic waterproof material. The core housing may be fixed to the first plug end and elastically abutted against the protective sleeve. The core housing may include a housing panel facing human body and a housing back panel opposite to the housing panel. When the vibration frequencies of the housing panel and the housing back panel is within a range of 2000 Hz to 3000 Hz, an absolute value of a difference between the first phase and the second phase may be less than 60 degrees.
