The present disclosure provides to a housing configured to receive an earbud. The housing comprises two power providing charging electrodes configured to charge the earbud when the earbud is positioned in the housing. The housing further comprises a first magnetic element arranged in the housing and having a geometry such that the first magnetic element encircles at least one electrode of the at least two electrodes, where the first magnetic element is configured to generate an attractive force for the earbud in combination with a second magnetic element provided in the earbud.

A hearing aid for placement in an ear canal of a user, includes: a shell; a faceplate comprising an upper face, and a lower face, and a circumference, the upper face being exposed when the shell is placed in an ear of the user; a coil arranged at the faceplate; and a button arrangement comprising a plunger configured to control an integrated circuit arranged below the coil, the coil comprising one or more windings, the one or more windings being circumferential of an inner cavity of the coil with respect to a center or longitudinal axis of the coil, the button arrangement being configured such that the plunger in at least one position extends through the inner cavity of the coil for engaging the integrated circuit.

A hearing device and related methods are disclosed. The hearing device comprises a housing comprising a wall, a microphone inlet comprising a through-going opening, a microphone arranged within the housing for receiving audio via the microphone inlet, a first filter device comprising a first filter material, the first filter device being arranged at the microphone, and a second filter device substantially having the shape of a torus or a hollow cylinder and comprising a second filter material, the second filter device being arranged at the wall, wherein the first filter device is arranged between the microphone and the second filter device, and wherein the through-going opening comprises an outer recess in an outer surface of the wall, wherein the second filter device is arranged in the outer recess.

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.

The present disclosure relates to a neckband earphone structure. The earphone structure includes at least one compartment, at least one earphone body and at least one earphone cable. The compartment is connected to a hanging ring, an electronic component is provided, in the compartment, one end of the compartment is provided with a female socket, one end of the earphone cable is provided with a male plug, the other end of the earphone cable is connected to the earphone body, the male plug is used for forming a pluggable connection with the female socket, and the earphone cable is docked with the female socket through the male plug to form a fixed connection with the compartment and establish an electrical connection with the electronic component in the compartment. In the present disclosure, the pluggable connection between the male plug and the female socket realizes a detachable connection between the earphone cable and the compartment. When in use, the male plug is directly inserted into the female socket, and when replacement or maintenance is needed, the male plug can be directly unplugged, so that the earphone cable and the earphone body are detached from the compartment of the hanging ring, thus meeting replacement/maintenance requirements of users and improving the use convenience.

The invention relates to a tool for inserting an ear-tip of a hearing aid into an auditory canal of an end user. The tool comprises a first part and a second part, which are movable in relation to each other around at least one pivot joint. A cavity for receiving a holding portion of the ear-tip is provided between the first and the second part, which cavity is enlarged when a second portion of the first part and a second section of the second part are pressed together.

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.

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 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.
