An earbud includes a housing that includes a driver assembly positioned within the housing forming a front volume in front of the driver and a back volume behind the driver. An acoustic insert is positioned behind the driver assembly and attached to an interior surface of the housing such that it forms a bass channel that is routed from the back volume to a vent in the housing.

An apparatus for charging a portable wireless listening device including a housing having a socket to receive the portable wireless listening device; a battery; wireless circuitry that enables the apparatus to communicate wirelessly with a host device; power transmitting circuitry configured to provide power to the portable wireless listening device when the device is received in the socket to charge a battery within the portable wireless listening device; and a processor configured to configured to establish a wireless communication protocol between the portable wireless listening device and the host device.

The present invention provides an earphone, including: an earphone base; an earphone plug, where the earphone plug is disposed on the earphone base; an eject pin configured to remove a card tray of a mobile terminal, where the eject pin is disposed in the earphone plug and the eject pin is connected to the earphone base by using a spring; and a pin controller, where the pin controller is connected to the earphone base, and the pin controller controls the eject pin to extend out of the earphone plug along an axial direction of the earphone plug or to retract into the earphone plug.

There is provided a noise reduction headset having multi-microphone and a noise reduction method. One embodiment of the headset includes a headband and headset bodies respectively connected to both ends of the headband, wherein the headset further includes a microprocessor and at least three microphones disposed on an outer surface of the headset body; the microprocessor is configured to select the microphone closest to a target sound source as a main microphone according to a comparison of sound signals picked up by respective microphones, select the microphone farthest from the main microphone as an auxiliary microphone according to a preset relative position of respective microphones, and execute a noise reduction algorithm by using a first sound signal picked up by the main microphone and a second sound signal picked up by the auxiliary microphone as inputs of the noise reduction algorithm so as to realize noise reduction. According to the embodiment, the noise reduction performance can be ensured under the condition that the user does not wear the headset normally.

A headphone device having an earcup that is configured to form a portion of an acoustic assembly of a headphone device. The earcup includes a seamless three-dimensional cover. The cover is formed from a continuous fabric of interlocking yarn. The cover can include portions having different performance characteristics, such as acoustic properties and/or comfort properties, that can be provided using different knit patterns and/or different fabric materials.

An apparatus for charging a portable wireless listening device including a housing having a socket to receive the portable wireless listening device; a battery; wireless circuitry that enables the apparatus to communicate wirelessly with a host device; power transmitting circuitry configured to provide power to the portable wireless listening device when the device is received in the socket to charge a battery within the portable wireless listening device; and a processor configured to establish a wireless communication protocol between the portable wireless listening device and the host device.

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.

An earpiece in accordance with at least some embodiments of the present technology includes a housing and a speaker within the housing. The earpiece also includes an antenna at least partially embedded within a wall of the housing. The wall includes a window portion and an opaque portion extending around the window portion. The antenna is visible from outside the housing via the window portion. The window portion includes a transparent filler within an elongate groove in the wall. The antenna includes a radiating element within the groove, and feeding and shorting pins extending through respective openings between the groove to an interior of the housing. Making the earpiece can include disposing filler material over the radiating element, increasing a hardness of the filler material, and abrading an outer surface of the wall at the filler material to form a smooth surface.

An earpiece includes an earbud that supports at least one electrode, and an ear tip that includes a hydrogel. The ear tip is configured to be coupled to the earbud such that the hydrogel overlies the at least one electrode and such that the hydrogel is disposed between the at least one electrode and the user's skin when the earpiece is worn.

A method of generating a filter according to an embodiment includes producing a shaped object to correspond to a user's ear canal using an impression material, producing the user's ear impression based on the shaped object, installing a microphone in an ear canal part penetrating to an inner ear side of the ear impression, installing an earphone or a headphone in the ear impression, measuring transfer characteristics by the microphone collecting a measurement signal output from the earphone or the headphone, and generating a filter based on the transfer characteristics.
