This present disclosure discloses an acoustic output device comprising: an acoustic driver that includes a diaphragm and a magnetic circuit structure, wherein a side of the diaphragm facing away from the magnetic circuit structure forms a front side of the acoustic driver, a side of the magnetic circuit structure facing away from the diaphragm forms a back side of the acoustic driver, the diaphragm vibrates so that the acoustic driver radiates sound outward from its front and back, respectively; a housing structure configured to carry the acoustic driver, wherein the back side of the acoustic driver and the housing structure form a back cavity, and different side walls of the back cavity are connected by a curved structure; the housing structure includes at least one sound outlet hole, the at least one sound outlet hole is acoustically coupled with the back cavity.

Disclosed are an acoustic module and an electronic product. The acoustic module comprises: a module housing, comprising an upper housing and a lower housing, wherein the upper housing of the module has a side wall and a top wall, the side wall has a through hole thereon, a distance between an upper edge of the through hole and the top wall is greater than or equal to one half of an overall height of the side wall, and the upper housing is capable of being fastened onto the lower housing; a fixing member; and a microphone; wherein the fixing member is fastened and fixed in the upper housing, the fixing member is configured to fix the microphone on an inner surface of the top wall, and the fixing member has a sound channel formed therein through which the microphone and the through hole are connected and are in communication.

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.

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.

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.

Various aspects include ported wearable audio devices. In certain implementations, a wearable audio device includes: a first cavity; a second cavity; a third cavity; a driver disposed between the first cavity and the second cavity, the driver configured to provide an acoustic output; a first mass and/or resistive port connecting the second cavity and the third cavity; and a second mass and/or resistive port connected to the third cavity.

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.

A headphone includes a speaker unit, a baffle plate, an ear pad, and a grille. The baffle plate is configured to support the speaker unit. The ear pad is configured to surround an acoustic space in which a sound emitted from the speaker unit is transmitted toward an ear of a listener. The grille is configured to cover the speaker unit. The grille has a hole and a cavity connected to the hole.

A headphone include a speaker unit, a baffle plate, and an ear pad. The baffle plate supports the speaker unit. The ear pad is attached to a front surface of the baffle plate. The baffle plate has at least one cell having a cavity. A part of the at least one cell has a hole communicated with the cavity. The hole is provided in at least one of the front surface of the baffle plate and a back surface of the baffle plate opposite to the front surface.

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.
