Embodiments describe an eartip including an eartip body having an attachment end and an interfacing end opposite from the attachment end. The eartip body can include an inner eartip body having a sidewall extending between the interfacing end and the attachment end, the sidewall defining a channel and having a first thickness near the attachment end and a second thickness different from the first thickness at the interfacing end. The eartip can also include an attachment structure coupled to the inner eartip body at the attachment end, the attachment structure having an inner surface and an outer surface. The attachment structure can include an upper region interfacing with the sidewall and defining discrete through-holes, a lower region below the upper region where the inner surface defines a plurality of recesses positioned around the lower region, and a mesh extending across the channel and into the upper region.

An open-ear headphone with an acoustic module that is configured to be located at least in part in a concha of an outer ear of a user. The acoustic module includes an acoustic transducer, and a sound-emitting opening that is configured to emit sound produced by the acoustic transducer. A body is coupled to the acoustic module and includes a first portion that is configured to pass over an outer side of at least one of an anti-helix and a helix and a lobule of the outer ear, and a second portion that is configured to be located behind the outer ear.

Embodiments of the present application provide a bistable hinge for an earphone charging case and the earphone charging case. The bistable hinge includes an installation base, a connecting member, and an elastic member. The connecting member is rotatably connected to the installation base, the connecting member has a rotating axis, and the connecting member has a first stable position, a critical position, and a second stable position, the critical position being between the first stable position and the second stable position. The elastic piece is loaded between the installation base and the connecting member. When the connecting member is offset from the critical position at either side along the rotating direction, the elastic piece exerts a drive torque on the connecting member so as to drive the connecting member to move to the first stable position or the second stable position.

A headphone is configured to be used in combination with an in-ear earphone, and includes: an earmuff configured to be fitted over an auricle; an earmuff pickup arranged on an outer side of the earmuff and configured to collect an environmental sound; and a first speaker arranged on an inner side of the earmuff and configured to perform at least one of following actions: playing a noise-cancellation sound corresponding to the environmental sound collected by the earmuff pickup, or playing an audio. When the headphone is in use, the inner side of the earmuff and the auricle define an accommodating space for accommodating a part of the in-ear earphone exposed out of an external auditory canal. The headphone and the auricle define an accommodating space for accommodating the in-ear headphone.

Systems, methods, devices and non-transitory, computer-readable storage mediums are disclosed for identifying, by a processor of a wireless device that is coupled with a charging case, an enable command received from the charging case; and transmitting, by the processor based on the enable command, an advertisement signal that includes information related to an identification of the wireless device.

An electronic device includes a first housing, a second housing including a cover, a hinge engaging portion, and a hinge protrusion, and a hinge structure configured to rotate the second housing relative to the first housing, the hinge structure including a first base facing the hinge engaging portion and a second base connected to the first base, and the second base includes a first contact surface contacting the hinge protrusion as the second housing transitions between the closing position and the intermediate position, and a second contact surface contacting the hinge protrusion while the second housing transitions between the intermediate position and the opening position.

A wireless earphone, a wireless earphone box, and a wireless earphone device. The wireless earphone includes a first body and a second body. A first end face of the first body is provided with a first magnetic member. A second end face of the second body is provided with a second magnetic member. An outer surface of the second body is provided with a third contact. The second body includes a first battery. The third contact is energized to cause the first body and the second body to be in a connected state or separated state.

Disclosed is an earphone system. The earphone system includes a charging box and an earphone, which is detachably assembled in the charging box. The charging box includes a processing module provided with a first identification time period, a power outputting module and a first switch module. During the first identification time period when the earphone is connected to the charging box, the earphone system is in a test mode, and the first switch module is switched for the charging box to transmit power to the earphone through the power outputting module and the first switch module. After the earphone is connected to the charging box for more than the first identification time period, the earphone system is in a communication mode, and the first switch module is switched for the charging box to transmit a data signal to the earphone through the processing module and the first switch module.

The present disclosure relates to a wirelessly rechargeable hearing device, a charger for a wirelessly rechargeable hearing device, and a system comprising a wirelessly rechargeable hearing device and a charger for the wirelessly rechargeable hearing device.

A system for generating processed audio signals may include an earphone comprising a microphone configured to capture sounds from an environment of the earphone, a first communication component, and a first processor; and an earphone case comprising an earphone compartment configured to receive the earphone, a second communication component, and a second processor. The first processor may be programmed to receive a captured audio signal representative of the sounds captured by the microphone; and transmit the captured audio signal via the first communication component. The second processor may be programmed to receive the captured audio signal via the second communication component; generate a processed audio signal based on analysis of the captured audio signal; and transmit the processed audio signal via the second communication component to the first communication component.
