A cord containment adaptor can be adaptively anchored or fixed to or removed from an earphone cord of a set of earphones by hand via an anchor slot of the adaptor. The anchor slot can have a frame or structure that may have multiple earphone cord entrapment chambers and/or an offset or non-linear path leading to an earphone cord entrapment chamber or chambers to help anchor the cord containment adaptor on the cord segment to prevent inadvertent dislodgement of the cord containment adaptor from the earphones. The structure of the anchor slot can be rigid and serves to firmly grip or compress earphone cord segments positioned between gapped-apart opposing sidewalls within the anchor slot. Entrapment chambers of the anchor slot are connected to every other entrapment chamber via cord passageways through which an earphone cord segment can pass. The cord containment adaptor may contain cord containment slots separate from the anchor slot. When a cord containment adaptor is anchored via the anchor slot, earphone cord segments can be gripped into slots in a manner that contains loose cord ends and helps prevent tangling of earphone cords when the earphones are stored or not in use. The adaptor can remain fixed to an earphone cord segment during audio listening by a user and during storage of an earphone set.

The present disclosure provides a loudspeaker device. The loudspeaker device may include an earphone core configured to transfer an electrical signal to a vibration signal; an auxiliary function module configured to receive an auxiliary signal and perform an auxiliary function; a first flexible circuit board configured to electrically connect to an audio signal wire and an auxiliary signal wire of an external control circuit, the audio signal wire and the auxiliary signal wire being electrically connected with the earphone core and the auxiliary function module, respectively through the first flexible circuit board; and a core housing configured to accommodate the earphone core, the auxiliary function module, and the first flexible circuit board. The wiring process inside the loudspeaker device provided in the present disclosure may be simplified, thereby further reducing a volume of the loudspeaker device.

Detachable wearable electronic eyeglasses and head mounted gear with a plurality of electronic functions and interchangeable electronic function, and a wearable computer with optimal weight distribution and stretchable arms.

Hands-free electronic devices and electronic functions that can be worn on the surface of the body in a biologically fit manner are described. The embodiments provide a convergence between electronic products, and biological, anatomical, and biomechanical aspects of the human body while providing hands-free and interchangeable wearable electronic apparatuses that can interact with human senses and physiology of a human body in a practical manner.

An extension cord system includes an electronic device that may store audio data. A case is provided and the electronic device is removably positioned therein. A pair of headphones is provided. The headphones are selectively electrically coupled to the electronic device. An extension cord is selectively electrically coupled between the electronic device and the pair of headphones. The extension cord engages the case when the extension cord is electrically coupled to the electronic device. Thus, the extension cord is inhibited from being unplugged from the electronic device.

Wearable electronic device includes a neck loop worn on a neck with two electromechanical units; two in-ear earphones; two earphone cords. Each unit has an earphone cord winding mechanism including (i) a spool for winding the earphone cord; (ii) a double drive mechanism including an electric motor, a reducer, and a spiral spring; (iii) an engagement mechanism for engagement between the drive mechanism and the spool; and (iv) a lock mechanism. One unit has a motor control key for the electric motor and the lock mechanism. One end of the cords is connected to one of the earphones and the other end to one of the spools. The units are mechanically connected to each other to prevent twisting, and to the neck loop so that one of the units is on the left side of the chest, and the other electromechanical unit is on the right side of the chest.

A set of headphones and audio system comprises a first set of buttons for controlling a volume level of transmitted audio to the headphones and a second set of buttons for controlling a volume level of external audio played by the headphones. The transmitted audio comprises audio received from an audio source such as an electronic device and the external audio comprises surrounding ambient noise received by a microphone coupled to the headphones. With the first set of controls and the second set of controls a user is able to adjust the volume level of the transmitted audio and the volume level of the external audio in order to listen to the transmitted audio while still interacting with the surrounding environment.

A hearing protection device is presented. The device has a first earmuff connected to a second earmuff by a connector. Each of the first and second earmuffs are configured to receive an ambient sound and provide a dampened ambient sound to a wearer. The device also has a cable, with a cable length, that extends from the first earmuff to the second earmuff. The cable is coupled to the connector by a connection assembly. The connection assembly comprises a plurality of connection mechanisms arranged in a connection plan. Such a hearing protection device gives more freedom of placing the cable in a compact arrangement.

A specialized audio/instrument cable with built-in digital signal processing capabilities that adds digital audio sampling capabilities that allows the user to trigger synthesized sounds or virtual musical instruments from within the cable itself to affect the sound generated from an instrument or microphone such that the cable is the only connection needed between the instrument or microphone and an output device. Using voice recognition, the specialized cable can select an audio effects chain algorithm and/or sampled sound algorithm extrapolated from a musical digital audio fingerprint (MDAF) created from a desired musician's instrument to alter the sound of the input instrument's audio.

The system includes an electronic device connected to a cord that can be unreeled and reeled in by a cord reel, and a management apparatus that can communicate with the electronic device. In the system, the cord-reel-use detector is disposed in the electronic device, and detects use of the cord reel. The memory is disposed in the electronic device and/or the management apparatus, and stores an amount of use of the cord reel. The controller is disposed in the electronic device and/or the management apparatus, and determines the use of the cord reel on the basis of the detection made by the cord-reel-use detector. The controller changes the amount of use of the cord reel in response to the electronic device having been replaced with another electronic device or in response to the cord reel having been replaced with another cord reel.
