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.

In an embodiment a wireless earphone includes an earbud portion having a speaker module, a stalk portion having a battery, wherein the earbud portion is connected to one end of the stalk portion, a circuit board and a first antenna being a slot antenna, wherein the circuit board extends from the earbud portion to an end of the stalk portion away from the earbud portion, wherein the circuit board is connected to the speaker module and the battery, wherein the circuit board comprises a reference ground, the reference ground extending from one end of the circuit board to another end of the circuit board, and wherein a slot is disposed on the reference ground forming a radiator of the slot antenna, the slot being located in the stalk portion and extending along a length direction of the stalk portion.

An electronic device is disclosed. The electronic device according to the present disclosure includes a body, a neck formed at one side of the body, and a head formed on the neck, wherein the head comprises: a circular part connected to the neck; a protrusion part protruding from one side of the circular part and having a curvature that is greater than a curvature of the circular part; a speaker hole formed at at least one of the circular part and the protrusion part; and a band part formed at the periphery of the speaker hole, and the thickness of the band part may be greater than the thickness of the circular part or the protrusion part around the band part.

The present disclosure provides a sound output device, a sensory sound source adjustment method, and a volume adjustment method. The sensory sound source adjustment method includes: obtaining a volume difference between the first sound wave and the second sound wave; and adjusting a sound generation time difference between the first sound wave and the second sound wave. The volume adjustment method includes: obtaining a volume difference between the first sound wave and the second sound wave; and adjusting an amplitude difference between the first excitation and the second excitation. The sound output device and the sensory sound source adjustment method may correct an shift of a sensory sound source perceived by a user; and the sound output device and the volume adjustment method may correct a volume difference between a first speaker and a second speaker.

An earphone comprising a rear chamber and a vent structure. The vent structure comprises a longitudinal recess in the housing wall, which recess is defined by a bottom wall and recess walls connecting the bottom wall and the housing wall, a recess opening in the recess, which recess opening connects the recess and the rear chamber, a mesh device arranged parallel with the bottom wall, whereby a longitudinal recess cavity is provided between the bottom wall and the mesh structure.

The invention also relates to the manufacturing such an earphone.

Disclosed herein are apparatuses for manipulation of an ear device within the ear canal of a subject. Also disclosed herein are methods of using said apparatuses for the insertion, removal, or other manipulations of the ear device. Also disclosed herein are methods of making the apparatuses, and kits containing the apparatus with instructions for use.

An earphone body includes an internal chamber, a transducer housed in the internal chamber, a first tuned vent and a second tuned vent. The transducer has a front surface facing a direction of insertion of the earphone body in use and a rear surface 6B. The internal chamber provides a proximal acoustic volume adjacent the front surface of the transducer and a distal acoustic volume adjacent the rear surface of the transducer. The first tuned vent and the second tuned vent each extend between the distal acoustic volume and the ambient environment and are adapted to provide fluid communication between the distal acoustic volume and the ambient environment. The first tuned vent is tuned to a first frequency and the second tuned vent is tuned to a second frequency, the first frequency being lower than the second frequency.

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.

A speaker comprises a housing, a transducer residing inside the housing, and at least one sound guiding hole located on the housing. The transducer generates vibrations. The vibrations produce a sound wave inside the housing and cause a leaked sound wave spreading outside the housing from a portion of the housing. The at least one sound guiding hole guides the sound wave inside the housing through the at least one sound guiding hole to an outside of the housing. The guided sound wave interferes with the leaked sound wave in a target region. The interference at a specific frequency relates to a distance between the at least one sound guiding hole and the portion of the housing.
