A speaker unit detachably mountable to a hearing aid device body configured to be positioned behind an ear of a wearer is disclosed. Further, hearing aid device system comprising the speaker unit is disclosed. The speaker unit comprises a contacting unit comprising at least one contact element and configured to be detachably mountable to a hearing aid device connector of said hearing aid device. The speaker unit further comprises a speaker unit body configured to be positioned at least partly in an ear canal of the wearer and comprising an output transducer unit configured to provide an acoustic signal based on an electrical signal input to said output transducer unit via said at least one contact element. The speaker unit further comprises a connecting unit provided between said speaker unit body and said contacting unit and including at least one wire configured to electrically connect said speaker unit body and said contacting unit. Further, the speaker unit comprises a memory unit configured to store data relating to said speaker unit.

Various aspects include electronic devices with connection-enhancing, electrostatic discharge (ESD) protection features. In some examples, an electronic device includes: a housing; and a detent spring internal to the housing, where the detent spring (i) is positioned to contact a feature that is at least partially external to the housing and (ii) functions as an electrostatic discharge (ESD) sink.

An electronic module group can include an electronic module including a first housing defining a housing cavity; a power supply driving module positioned within the housing cavity; and a first concentric terminal connected in electrical communication with the power supply driving module by a first wire and a second wire; and a second concentric terminal rotatably connected in electrical communication with the first concentric terminal, the second concentric terminal configured to transmit power to the first concentric terminal.

A light speaker structure with a ring handle includes a speaker body, a speaker enclosure, a lighting mechanism and an auxiliary mechanism. The speaker body is mounted within the speaker enclosure, and the auxiliary mechanism is mounted on the speaker enclosure. The lighting mechanism includes a lampshade, a light strip, and LED beads. The light strip is mounted within the lampshade. The LED beads are fixedly connected to the light strip and electrically connected to the speaker body. The light strip is disposed in a laterally inverted C-shape around the speaker enclosure. The lampshade covers the light strip, so that the light strip is held between the lampshade and the speaker enclosure. The light strip and the lampshade are so shaped that they can be arranged around the speaker enclosure, thereby achieving a better lighting effect, providing a larger lighting area and producing a stereoscopic effect.

Disclosed herein are battery-free charging systems for wireless headphones that have at least one proprietary electrical contact provided to charge an on-board power source of the wireless headphone. The battery-free charging system comprises a cable having a first end and a second end, a headphone socket coupled to the first end of the cable, a connector coupled to the second end of the cable, the connector for connecting the battery-free charging system to an external power source, and circuitry coupled to the headphone socket and to the connector. The headphone socket is configured to receive the wireless headphone, to couple the at least one proprietary electrical contact to the external power source, and to allow continued use of the wireless headphone while charging. The circuitry is configured to detect an orientation of the wireless headphone within the headphone socket and provide a charging signal appropriate for the detected orientation.

A Universal Serial Bus (USB) audio device kit includes a USB peripheral audio device and a passive USB-to-analog audio adapter. The USB peripheral audio device includes a USB interface configured to communicatively interface the USB audio peripheral device with a USB host device. The passive USB-to-analog audio adapter is configured to electrically interface the USB peripheral audio device with analog audio equipment via the USB interface.

One or more sensors are configured to contextualize a series of user generated movements to control one or more electronic devices. For example, a set of earphones comprises one or more sensors for sensing a location of the earphones. The one or more sensors enable earphones such as a pair of bluetooth or earphones wirelessly coupled to a bluetooth enabled electronic device, the capability to understand the configuration of use of the earphones. Based on a location and use or non-use of the earphones, one or more contextual responses is able to be applied for a given action.

An audible beacon system includes an audible beacon chassis. A port connector is included on the audible beacon chassis and is configured to connect to a port on a computing device. An audible beacon device is coupled to the audible beacon chassis. An audible beacon driver device is included in the audible beacon chassis, is accessible via the port connector, and is configured to drive the audible beacon device to cause the audible beacon device to generate an audible sound. A storage device is included in the audible beacon chassis, is accessible via the port connector, and includes information that is configured to allow a computing device that is connected to the port connector to access the audible beacon driver device and cause the audible beacon driver device to drive the audible beacon device.

A detachable headband for a headphone system can incorporate a headband identification circuit that stores or encodes a headband identification parameter value. When the headband becomes attached to an ear cup, the headband can transmit the headband identification parameter value to the ear cup.

An electronic module can include a first housing defining a housing cavity, the first housing defining a first end and a second end positioned opposite from the first end, the first end defined by a shaft of the first housing, the shaft defining external threading, the first housing defining a housing opening to the housing cavity at the second end; an LED lamp board positioned within the housing cavity, the LED lamp board configured to emit light through the housing opening; a power supply driving module positioned within the housing cavity at least partially between the LED lamp board and the shaft; and a first concentric terminal connected in electrical communication with the power supply driving module, the first concentric terminal extending at least partially through the shaft, the first concentric terminal configured to rotatably connect in electrical communication with a second concentric terminal.
