The present disclosure relates to a loudspeaker. The loudspeaker may include a loudspeaker mechanism, a fixing mechanism, and a connector. The loudspeaker mechanism may be configured to generate a vibration signal and transmit the vibration signal to the human body. The fixing mechanism may be configured to support and maintain the position of the loudspeaker mechanism. The connector may be configured to connect the loudspeaker mechanism with the fixing mechanism. The loudspeaker mechanism may at least include a first fixed position and a second fixed position. The first fixed position may be a fixed position of the loudspeaker when the loudspeaker is in a non-working state. The second fixed position may be a fixed position of the loudspeaker when the loudspeaker is in a working state. The connector may be configured to switch the loudspeaker mechanism between the first fixed position and the second fixed position.

An electronic device may include a power management subsystem that soft-starts freshly charged batteries upon connection. The device may be configured to operate on power from a number of batteries less than the greatest number of batteries that may be concurrently connected. Because the soft-start reduces current inrush upon connection of a fresh battery, the device may continue operating as fresh batteries are connected and depleted batteries are disconnected.

The present disclosure relates to a loudspeaker. The loudspeaker may include an earphone core, an auxiliary function module, and a flexible circuit board. The earphone core may be configured to convert an electric signal into a vibration signal. The auxiliary function module may be configured to receive an auxiliary signal and execute an auxiliary function. The flexible circuit board may be configured to electrically connect to an audio signal wire and an auxiliary signal wire of an external control circuit, and electrically connect the audio signal wire and the auxiliary signal wire with the earphone core and the auxiliary function module via the flexible circuit board, respectively. The loudspeaker in the present disclosure may simplify the wire routing and improve sound quality.

Techniques for providing wearable electronic devices with electrical components are disclosed. The electrical components can provide electrical technology to eyewear to facilitate audio support including enhanced hearing. The electrical components can operate independently or together with other electrical components provided elsewhere. The wearable electronic devices with electronic components can, for example, provide audio output, audio enhancements, or event-related audio content.

Smart glasses comprise a glasses frame. The smart glasses further comprise a pair of glasses legs connected to two lateral portions of the glasses frame respectively, each of the glasses legs having a first end and a second end, wherein the second end of each of the glasses legs bends inwardly to form a first arc portion. In addition, the smart glasses further comprise a pair of clamping members each disposed at one of the glasses legs, wherein each of the clamping members comprises an elastic clamping element, said elastic clamping element being disposed at the inner side of said second end, wherein said elastic clamping element having a free end that bends inwardly to form a second arc portion.

An eyewear retention device that comprises two retaining devices, each meant to be positioned on a temple member of a pair of eyeglasses. The retainer devices are meant to be positioned between the concha and pinna of the ear so that hold the eyeglasses on the nose of the wearer securely at the wearer's desired portion without any slippage of the eyeglasses along the nose.

In one aspect, a user-wearable illumination assembly includes eyeglass frames and a headlamp removably coupled to the eyeglass frames. Electrical circuitry may be integrated with the eyeglass frames. The headlamp and the eyeglass frames have mounting structure that cooperate to removably support the headlamp thereon. A light source is disposed within the headlamp and electrical communication between the light source and the electrical circuitry of the eyeglass frames is provided by electrical contacts associated with the mounting structures of the headlamp and eyeglass frames. In another aspect, a user-wearable illumination assembly for use with eyeglass frames includes a clip assembly that is selectively removably couplable to a bridge portion of the eyeglass frames, and a headlamp coupled to the clip assembly. The illumination assembly further includes a battery that is selectively removably couplable to the eyeglass frames and at least one electrical conductor coupling the battery to the headlamp.

A method for making smart glasses includes obtaining a temple pre-form made as a one-piece seamless shell structure with shell walls enclosing a hollow compartment. An opening at one end of the one-piece seamless shell structure provides physical access to insides of the hollow compartment. The method further includes disposing one or more smart glasses components in the hollow compartment through the opening in the shell structure, and attaching the temple pre-form with the one or more smart glasses components disposed in the hollow compartment to a frame of the smart glasses.

One stem reversible glasses include a first lens and a second lens. A stem having a proximal end and a distal end is connected adjacent one of the first lens and the second lens at the proximal end. An earpiece is connected adjacent the distal end of the stem, the earpiece including means for securing the earpiece to a right ear of a user when the glasses are in a first reading position and for securing the earpiece to a left ear of the user when the glasses are in a second reading position. A nosepiece is disposed between the first lens and the second lens dimensioned and configured for receiving a nose of a user when the glasses are in either the first reading position or the second reading position.

A glasses/cap system for separably coupling glasses to a cap and for securing the glasses to the hat in either a usage orientation or a storage orientation. The coupling components mainly consisting of complementary magnets and ferromagnetic materials located in reciprocal parts of the glasses and cap alone or in combination with push type or bungee type connectors.
