A wireless earphone comprises a transceiver circuit for receiving streaming audio from a data source over a local ad hoc wireless network. When the data source and the earphone are out of range, they transition automatically to an infrastructure wireless network. If there is no common infrastructure wireless network for both the data source and the speakerphone set, the earphone connects to a host server via an available wireless network.

The embodiments of the present application disclose an electronic device, and the electronic device includes: a device body and a camera apparatus, where a sound-emitting device is installed in the device body, a first sound cavity is provided on the device body, the first sound cavity has an opening that communicates with the outside, the camera apparatus is detachably installed in the first sound cavity, in a case that the camera apparatus is installed in the first sound cavity, the sound cavity of the sound-emitting device has a first volume value, in a case that the camera apparatus is separated from the device body, the sound cavity of the sound-emitting device extends toward the first sound cavity and has a second volume value, and the first volume value is smaller than the second volume value.

Modular smartband can include a plurality of coupled modules. The plurality of modules can include at least one core module having at least one processor and at least one peripheral module. Each of the plurality of modules has a coupler end and a receiving end disposed on opposing ends of the module, the coupler end configured to be received in the receiving end of an adjacent module. At least one of the plurality of modules can include a display and at least one the plurality of modules includes a battery.

A mobile terminal, an electronic device, and a host assembly may be disclosed. The mobile terminal may include a host assembly and a display assembly. The host assembly may include a base and a support. The base may include a first surface. The first surface may define a receiving groove. The support can be capable of being located in the receiving groove and unfolded relative to the base. The support may include an inner face. The display assembly may include a display face, a back face and a peripheral side face. When the support is unfolded with a first angle relative to the first surface of the base, the display face or the back face of the display assembly may be attached to the inner face, the peripheral side face of the display assembly may abut against the base at a bottom of the receiving groove.

A barcode scanner magnetically attachable to a smart phone includes a circuitry adaptor and a barcode-scanning device. The circuitry adaptor is plugged into a USB connector of the smart phone. The barcode-scanning device is magnetically and detachably connected to the circuitry adaptor, so that electricity and signals from the smart phone are transmitted to the barcode-scanning device, and barcode signals picked up by the barcode-scanning device are transmitted to the smart phone. When the barcode-scanning device undergoes external impact, the circuitry adaptor and the barcode-scanning device are detached from each other without damaging the USB connectors.

The present invention relates to a mobile device, preferably a cell phone, comprising a module holder for a camera module for capturing still images and/or moving images, said camera module having a coupling section and being releasably connectable to the module holder, wherein the module holder has a recess in which the coupling section is received when the camera module is connected to the mobile device. In the mobile device in accordance with the invention, provision is made that the recess of the module holder has a peripheral contour that is formed by a circular arc section and a secant section. The invention further relates to a corresponding camera module and to a mobile device system.

A radio frequency (RF) front end device has a signal traveling from a first antenna to a second antenna in an uplink path and a signal traveling from a third antenna to a fourth antenna in a downlink path. The device is under the control of automatic on/off controller (AOOC) which upon receiving a signal indication from a receive signal detector and amplifier (RSDA) turns on the operations of power amplifier (PA) and simultaneously turns off a low noise amplifier (LNA). This LNA is turned off when the power amplifier is turned on to prevent uplink path and downlink path forming a feedback loop which would result in oscillation, noise and interference.

Various components of an electronic device housing and methods for their assembly are disclosed. The housing can be formed by assembling and connecting two or more different sections together. The sections of the housing may be coupled together using one or more coupling members. The coupling members may be formed using a two-shot molding process in which the first shot forms a structural portion of the coupling members, and the second shot forms cosmetic portions of the coupling members.

A mobile electronic device includes a main framework having a motherboard, a back cover covering the main framework and having an expansion window, and an expansion unit is disclosed. The expansion unit includes a door cover covering the expansion window. The door cover includes a back plate and a lateral plate, the lateral plate having an opening. A functional module is disposed on an inner side of the door cover, electrically connected to the motherboard, and has a first side on which an operation interface is disposed. The operation interface faces the opening in the lateral plate.

An electronic device is provided. The electronic device includes a device body provided with an accommodation space and an opening communicated with the accommodation space, a function module having a first state and a second state, and an ejecting mechanism including a connecting rod, a slider detachably connected to the function module, a driving member, and a guide rail that is disposed on the slider. The driving member is disposed in the accommodation space, a first end of the connecting rod is hinged to the device body, a second end of the connecting rod slides along the guide rail, and the slider is configured to switch between a first position and a second position.
