Earphone having a controlled acoustic leak port

An earphone comprising an earphone housing having a wall comprising (1) a front side that joins (2) an end portion in which a primary sound output opening is formed, which joins (3) a face portion in which a secondary output opening is formed, which joins (4) a back side which joins the front side and encloses a driver, wherein the primary output opening is dimensioned to output sound generated by a diaphragm of the driver contained within the earphone housing into the ear and the secondary output opening is dimensioned to vent the ear to a surrounding environment, and wherein the primary output opening and the secondary output opening face different directions.

Vented acoustic transducers, and related methods and systems

An electronic device has an acoustic transducer with an acoustic diaphragm. The diaphragm has opposed first and second major surfaces. A front volume is positioned adjacent the first major surface. A back volume is positioned adjacent the second major surface. An elongated channel defines a barometric vent and extends from a first end fluidly coupled with the front volume to a second end fluidly coupled with the back volume, fluidly coupling the front volume with the back volume. The elongated channel may have a high aspect ratio (L/D), providing the vent with a substantial air mass. The elongated channel may be segmented to define a higher-order filter. For example, a segmented channel can have a cascade of repeating acoustic-mass and acoustic-compliance units, providing the barometric vent with additional degrees-of-freedom for tuning.

Earphone

The present invention relates to an earphone, comprising an earphone body, an earphone cord, and a fixing member. The earphone body includes an earplug portion, a connecting portion, and a body portion. The fixing member shaped as a ring, and the middle portion of the ring includes a through hole. The fixing member includes a top wall located at an edge of the ring. The top wall is made of an elastic material. Among them, the connecting portion is connected to the earplug portion and the body portion. The connecting portion passes through the through hole and is fastened in the fixing member, and the fixing member and the connecting portion are members of the earphone that are placed in the cavitas conchae of the human ear. The beneficial effects of the present invention are that since the top wall of the fixing portion is made of a material that is susceptible to deformation, adaptive deformation is performed to match the different cavitas conchae, when subjected to the compression of the cavitas conchae. Thus, this improves the comfort of the earphones.

Hearing device comprising a vent and an acoustic valve

The disclosure relates to a hearing device comprising an earpiece provided with a vent configured to provide for a venting of sound waves between an inner region of the ear canal and an ambient environment outside the ear canal; the earpiece further comprising an acoustic valve including a valve member moveable relative to the vent between different positions and an actuator configured to provide an actuation force for a movement of the valve member such that an effective open cross-sectional area of the vent can be modified by the movement of the valve member; the hearing device further comprising an output transducer configured to be acoustically coupled to the inner region of the ear canal.

HEADPHONE SEALING CUP

An earcup for a headphone, comprising at least one earcup comprising a front opening adapted to be adjacent to the ear of a user of the headphone, a baffle disposed within the earcup to define front and rear cavities, an outer cup arranged to accommodate the rear cavities, a first inner cup arranged within the rear cavity surrounding the front opening, a transducer and an earpad extending around the periphery of the front opening of the earcup arranged to accommodate the front cavity and the ear of the user, and wherein the earcup comprises a second inner cup arranged between the outer cup and the back-volume cup for providing an acoustic barrier between outside noise and the ear of the user.

WIRELESS EARBUD

An earbud includes a housing having a main body portion having a speaker port and a stoke extending from the main body portion; a radiator disposed in the stoke to radiate radio signals to the outside of the earbud; and a printed circuit board (PCB) configured to be electrically connected to the radiator. The radiator includes a first conductive pattern formed on a first surface in the stoke; a second conductive pattern formed on a second surface perpendicular to the first surface; and a connection portion configured to electrically connect the first conductive pattern and the PCB. The first conductive pattern and the connection portion may be configured to radiate signals in a first frequency band, and the first conductive pattern and the second conductive pattern may be configured to radiate signals in a second frequency band different from the first frequency band.

Earphone having a controlled acoustic leak port

An earphone comprising: an earphone housing having a cap portion and a body portion that interlock with one another to enclose a driver, the driver having a front face that outputs sound waves and a back face opposite the front face, the cap portion defines a first chamber coupled to the front face of the driver and the body portion defines a second chamber coupled to the back face of the driver, a first opening formed through the cap portion; a first port and a second port formed through the body portion and open to a surrounding environment; and a mesh coupled to the first opening, the first port or the second port.

Sound port adapter for microphone assembly

A one-piece sound port adapter for a microphone assembly includes a body member configured to be fitted over a sound port of the microphone assembly. The body member includes an acoustic channel defined in part by a cavity having a sound inlet and a sound outlet, where the sound outlet is acoustically coupled to the sound port. A wall portion of the body member extends into the cavity and configured to modify an acoustic property of the acoustic channel. When mounted, the one-piece sound port adapter converts the microphone assembly from a top or bottom port microphone assembly to a side-port microphone assembly.
