The present disclosure provides a magnetic system within a case for an electronic accessory. The case may include a housing portion and a lid coupled to the housing portion. Within the housing portion may be a housing magnet. The housing magnet may be oriented such that the magnetic field of the housing magnet is oriented transverse to a longitudinal axis of the case. The housing magnet may have a size and strength to magnetically couple the electronic accessory within a cavity of the housing. A hinge magnet may be located along an axis of rotation of the lid with respect to the housing. The hinge magnet and housing magnet may magnetically interact to form a bistable magnetic hinge. Thus, the one housing magnet may be large enough and have a strong enough magnetic field to perform various functions.

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.

Smart glasses are provided, which can be electrically connected to wireless earphones, where wireless earphones include a second electrical connection part. The smart glasses includes a main body and glasses legs rotatably connected to the main body. One glasses leg can be rotatably switched between a first position and a second position relative to the main body. The glasses leg includes a first electrical connection part. At least one of the glasses leg and the main body includes a battery module, and the first electrical connection part is electrically connected to the battery module. If the glasses leg is located at the first position, the glasses leg is separated from the wireless earphone. If the glasses leg is located at the second position, the glasses leg is connected to the wireless earphone, and the first electrical connection part is electrically connected to the second electrical connection part.

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.

The present disclosure relates to a pair of glasses. The pair of glasses may include a frame, one or more lenses, and one or more temples. The pair of glasses may further include at least one low-frequency acoustic driver, at least one high-frequency acoustic driver, and a controller. The at least one low-frequency acoustic driver may be configured to output sounds from at least two first guiding holes. The at least one high-frequency acoustic driver may be configured to output sounds from at least two second guiding holes. The controller may be configured to direct the low-frequency acoustic driver to output the sounds in a first frequency range and direct the high-frequency acoustic driver to output the sounds in a second frequency range. The second frequency range may include one or more frequencies higher than one or more frequencies in the first frequency range.

Disclosed are a communication control method, apparatus and system, and a charging case and a wireless earphone. The method includes: acquiring, when a charging case is connected with a first wireless earphone though a first power supply pin and a second power supply pin, first to-be-transmitted data if the charging case is to communicate with the first wireless earphone; and controlling a first single-pole double-throw switch to connect the first power supply pin with a first TxRx and level conversion circuit, sequentially transmitting a predetermined start code and the first to-be-transmitted data to the first wireless earphone through the first power supply pin, where the first wireless earphone controls a first predetermined charging pin to be connected with a second TxRx and level conversion circuit based on the predetermined start code, and receives the first to-be-transmitted data.

An earphone control method is applied to an earphone box provided with a first electrical contact, when the first electrical contact is in a charging state, the first electrical contact is configured for charging the earphone, and when the first electrical contact is a communication state, the first electrical contact is configured for establishing communication between the earphone box and the earphone, the method includes: in responding to that the first electrical contact is in the charging state, and the earphone box detects that a communication requirement exists between the earphone box and the earphone, adjusting a voltage level of the first electrical contact to send preset signals to the earphone; and upon receiving a response signal fed back by the earphone based on the preset signals, switching the first electrical contact to the communication state. An earphone box, an earphone and a computer-readable storage medium are also disclosed.

An earphone case is for storing a wireless earphone body, and includes a case body and a case cover. A top face and a side face of the case body each have an accommodating groove, the accommodating groove in the top face is configured to be fitted with an ear bud of the wireless earphone body, and the accommodating groove in the side face is configured to be fitted with a stem of the wireless earphone body. The case body is provided with a magnetic member for attracting the wireless earphone body.

A cradle includes a main body having a seating portion in which an earbud is seated, a folder body capable of being converted between a closed state and an opened state of the seating portion, and a hinge portion configured to couple the folder body to the main body, wherein the hinge portion includes a first hinge coupled to the main body, a second hinge coupled to the folder body, a shaft extending through the first hinge and the second hinge, a first magnet coupled to the first hinge, and a second magnet coupled to the second hinge or to the folder body, and wherein the first magnet and the second magnet maintain a repulsive force therebetween while the folder body is converted into the opened state from the closed state. The semi-automatic opening structure of the cradle is simplified so as to simplify the manufacturing process and reduce manufacturing costs.

An electronic device includes: a wireless communication circuit; a power management circuit; and a control circuit , and the control circuit may: in a state where the electronic device connects a first communication with a first audio output device by using the wireless communication circuit, or is electrically connected with the first audio output device by using the power management circuit, operate in a connection standby mode or in an advertise mode by using a first wireless communication address of the first audio output device; receive a signal for finding the first audio output device from an external electronic device, based on the first wireless communication address; and transmit a signal for letting the first audio output device output a notification to the first audio output device through the first communication, or transmit the signal to the first audio output device through the electrical connection.
