Various aspects include audio eyeglasses with a frame including: a lens region; a pair of arms extending from the lens region; a hinge coupling each of the pair of arms with the lens region; and a cable extending through each hinge, where each hinge includes: a body defining a cavity accommodating the cable; and a hinge mechanism within the body, the hinge mechanism having: a spring located in the lens region, the spring including at least one lever arm extending within the cavity; and a cam member contacting the lever arm of the spring, where the cam member includes: a first contact surface for resisting kickback from the spring when the audio eyeglasses are in a fully open position, and a second, distinct contact surface for resisting kickback from the spring when the audio eyeglasses are in a fully closed position.

Disclosed in the embodiments of the present application is a headset communication system. The headset communication system comprises: a bone conduction headset, comprising a first Bluetooth module; an intercom device, comprising a first external interface; an external communication module, comprising a second external interface and a second Bluetooth module. The external communication module is detachably provided in the intercom device and being coupled to the intercom device by means of the first external interface and the second external interface, and the bone conduction headset and the intercom device perform Bluetooth pairing by means of the first Bluetooth module and the second Bluetooth module so as to establish a Bluetooth connection.

Headphones include an earbud, including a knob-shaped body, an earbud tip extending from the knob-shaped body and configured to enter an ear canal of a listener, a harness strap interface disposed on the knob-shaped body and configured to removably accommodate a detachable harness strap.

A headband structure of a headphone, including a headband assembly and a telescopic adjustment module, is provided. The headband assembly has a steel belt. The steel belt has multiple positioning slots. The telescopic adjustment module includes a fixing base, an elastic sheet, and a positioning ball. The fixing base is slidably disposed to the steel belt. The elastic sheet is disposed to the fixing base, and the elastic sheet has an accommodating groove. The positioning ball is disposed in the accommodating groove, and the positioning ball is located between the steel belt and the elastic sheet. The elastic sheet constantly pushes the positioning ball to keep the positioning ball in contact with the steel belt, and the positioning slots are located on moving paths of the positioning ball.

The present disclosure provides an acoustic output apparatus. The acoustic output apparatus includes a speaker assembly, configured to convert an audio signal into a sound signal; an ear hook assembly, including an ear hook housing and a connecting part, the ear hook housing having an accommodating space to accommodate a battery assembly and/or a control circuit assembly, one end of the connecting part connecting to the speaker assembly, and the other end of the connecting part connecting to the ear hook housing, wherein the connecting part includes at least one first wire clamping part used to restrict a set of lead wires drawn out from the speaker assembly and extending into the accommodating space, the set of lead wires electrically connect the speaker assembly to the battery assembly and/or the control circuit.

The present disclosure discloses a bone conduction earphone. The bone conduction earphone may include a loudspeaker assembly. The bone conduction earphone may also include an ear hook assembly including a first ear hook housing, a connection member, and a second ear hook housing. One end of the connection member may be connected to the first ear hook housing, and the other end of the connection member may be connected to the loudspeaker assembly. The first ear hook housing may include a first sub-accommodating space, and the second ear hook housing may include a second sub-accommodating space. The first ear hook housing may be spliced and matched with the second ear hook housing by a first connection assembly such that the first sub-accommodating space and the second sub-accommodating space may be combined to form an accommodating space, and a length direction of the accommodating space may be perpendicular to a thickness direction of the accommodating space.

Various implementations include headphone systems. In one implementation, a headband for a headphone system, includes: a continuous spring section sized to extend over a head of a user; an earcup mount coupled with an end of the continuous spring section, where the earcup mount allows for both translation and rotation of an earcup relative to the continuous spring section without altering a length of the continuous spring section; and a friction assembly spanning between the continuous spring section and the earcup mount.

An earpiece retention assembly may include a cable portion pre-formed into an ear loop with a first end coupled to a non-insertion end of an earpiece. The cable portion may be configured to bias the earpiece toward the interior of the ear loop to define a default orientation.

The present invention relates to a totally foldable head strap. The virtual reality headset comprises of headphone bracket, back head member, front head, and head mounted display all of which can be rotatably connected and can be folded to reduce the carry and storing size. The head mounted display has two supporting bars that slide and snap inside the bar supports each attached at the front ends of the back head member. The front head member and back head member are rotatably connected from the inner side of the back head member.

A method for operating a bone conduction communication system can include establishing a communicable connection, operating a transducer in an input mode wherein the bone conduction transducers are configured to detect a vibration associated with a bone of the user; transmitting an audio signal over the communicable connection; and operating the transducers responsive to the audio signal.
