A modular audio system which includes an acoustic module configured to be removably engaged with a head-worn peripheral device. In some examples, the head-worn peripheral device is a pair of eyeglass frames and the acoustic module is configured to removably secure to a socket arranged on the inside face of the temples of the eyeglasses. The acoustic module can slidingly, pivotably, and/or magnetically engage with the socket such that, when secured, the acoustic module is configured to generate acoustic energy in the form of audible sound proximate a user's ear while the user is wearing the head-worn peripheral device. In other examples, the temples of the head-worn peripheral device are configured to slidingly engage with a sleeve, where the sleeve includes a pocket configured to slidingly engage with the acoustic module.

Disclosed are a TWS earphone, a method and apparatus for reducing earphone energy consumption, and a computer-readable storage medium. The method for reducing earphone energy consumption comprises: determining whether a target earphone is in an off-ear state and is not placed in a charging case; if so, acquiring a timekeeping duration since the target earphone is taken off of an ear; determining whether the timekeeping duration exceeds a first preset threshold value; and if the timekeeping duration exceeds the first preset threshold value, performing energy consumption reduction processing on the earphone. According to the present application, the duration since an earphone is taken off of an ear is evaluated for the earphone that is taken off of the ear and is not placed in a charging case, so as to perform energy consumption reduction processing on the earphone that has been taken off of the ear for a relatively long duration, such that unnecessary power consumption of the earphone when same is in a not-in-use state can be effectively reduced, and the effective service time of the earphone after charging is prolonged.

The disclosure provides a charging device and a method for positioning an electronic device. The method includes: in response to determining that a positioning request signal from an electronic device is received, enabling multiple antennas; controlling each antenna to receive a first radio frequency signal broadcast by the electronic device, and determining an arrival angle of the first radio frequency signal and a distance between the electronic device and the charging device based on the first radio frequency signal received by each antenna; and determining a relative position between the charging device and the electronic device based on the arrival angle and distance.

A charging device of a hearing aid has a charging unit, which has a housing with a housing cover and a magnet arranged therein and movably guided in a longitudinal direction. At one longitudinal end, a contact is attached on the magnet for the detachable, direct electrical contacting with a counter contact of the hearing aid. The contact is electrically connected by a line to a charging circuit, wherein the housing cover has an opening, within which the contact is inserted. The charging device is part of a system having a hearing aid.

An external audio device includes a USB (Universal Serial Bus) plug, an audio socket, a USB communication circuit, an audio socket detection circuit, a first power circuit, a second power circuit, and a control circuit. The USB communication circuit establishes a connection with a computer device coupled to the USB plug according to the communication protocol of USB. The audio socket detection circuit detects a plug-in state of the audio socket. The first power circuit generates a second power to the USB communication circuit according to a first power received from the USB plug. The second power circuit generates a third power to the audio socket detection circuit according to the first power. The control circuit enables or disables the first power circuit according to the plug-in state of the audio socket.

An apparatus includes a ear piece case housing, a receptacle within the ear piece case housing and configured to hold an earpiece, an earpiece connector at the receptacle and configured to electrically connect with the earpiece, and electromagnetic shielding materials integrated into the ear piece case housing to electromagnetically isolate the earpiece while the earpiece is contained within the case housing. The ear piece case housing may include a charger and a removable slide cover adapted for sliding over the charger.

A mobile device includes; a power line communication ( ) module that communicates data with an external device via a power line, receives a first preamble signal from the external device during a first preamble interval, receives a voltage signal as the data during a data reception interval following the first preamble interval, and demodulates the voltage signal to provide a demodulated voltage signal, a frequency/duty detector that detects a frequency and a duty of the first preamble signal, and a control circuit that performs signal a data determination operation on a demodulated voltage signal during a data period and using the first detected frequency and the first detected duty.

The invention relates to an earphone protective case comprises a protective case body and a cover which is arranged at one end of the protective case body and is detachably connected with the protective case body; one side of said protective case body is provided with a groove and a slide, two sides of said groove are provided with a sliding track, two sides of said slide is matched with the sliding track of the groove and can slide in the sliding track at two sides of said groove; the other end of the slide that is close to the protective case body is provided with a hook that is matched with the shape of the other end of protective case body; after the slide is taken out, a support frame that can support the mobile phone is formed between said hook and other end of said protective case body.

A hearing device plug connector may include a first connector component and a second connector component, wherein the hearing device plug connector includes a latching mechanism for securing the first connector component and the second connector component against unintended disconnection, wherein the latching mechanism includes a catch and a complementary latch component which are in latching engagement when the first connector component and the second connector component are connected, wherein the catch is moveable against a spring force from a latching position into a release position when connecting or disconnecting the first connector component and the second connector component, and wherein in the latching position the catch can engage with the complementary latch component and in the release position the catch can disengage from the complementary latch component. The hearing device plug connector may further include a sealing element for providing a seal between the first and second connector components.
