An accessory for eyeglasses that functions as a combined hearing aid and/or eyeglasses retention device which can maintain housings of behind the ear (BTE) hearing aids in place on a user's ears. The combined hearing aid and/or eyeglasses retention device can also maintain eyeglasses from slipping down the nose of a user which also maintains the device at its optimal position to retain housings of BTE hearing aids in place. The combined hearing aid and/or eyeglasses retention device also prevents displacement of BTE housing(s) off a user's ears when a user removes a mask. The combined hearing aid and/or eyeglasses retention device can also be a ‘standalone’ eyeglasses retention device when a user does not wear BTE hearing aids.

A combined storage case for electronic device accessories has a base case, a first case for receiving a transmission line or an earphone, and a power bank for charging an electronic device. The base case is provided with at least one first receptacle, a plug, and a car charger. An inner surface of the base case is provided with two first connecting parts. The first case is detachably connected with the base case via two second connecting parts. The power bank is detachably connected with the base case via two third connecting parts. The power bank and the base case engage with each other via a positioning recess and a position protrusion. The power bank and the first case are stably mounted on the base case by two magnetic elements attracting each other.

A sound-limiting device is provided, that includes an earplug body of a resilient elastomeric material, and that has a first portion whose shape corresponds generally to the shape of the vertical canal of a dog's ear canal, and a second portion sized and configured to flex through the elbow region of the dog's ear canal and into the horizontal canal. A spring element can be encapsulated in the first portion of the earplug body, and configured to apply a spring bias radially outward from an axis extending a length of the earplug body. The spring element is of a shape memory alloy having a transition temperature that is below a normal body temperature of a dog. The device can also include a sound conditioning element configured to produce a signal that is audible to an animal wearing the device.

A system and method for wireless charging a wireless earbud. The wireless earbud having a body that includes a passive magnetic shield and a coil. The coil is wound around a portion of the body comprising the passive magnetic shielding. The wireless earbud receiving wireless energy in response to the placement of the body within an electromagnetic field, which results in the charging of a battery of the wireless earbud.

A hearing aid has a housing and an antenna. The housing has a housing shell to be worn in the ear. The antenna is designed for signal transmission via a radio connection. The housing shell has an inner side. The antenna is inserted into the housing shell and extends along the inner side. There is also described a corresponding antenna and a method for producing a corresponding hearing aid.

A hearing aid for placement on the head. The hearing aid includes a first part comprising an acoustic input transducer adapted to convert an ambient sound picked up at an ear of the user to an electric signal, a signal processor adapted to process the electric signal according to specifications of the user into a processed electric signal, and an output transducer adapted to convert the processed electric signal into a transmission signal, and a second part linkable to said first part by magnetic forces and comprising a receiver adapted to receive the transmission signal and convert the transmission signal to an output signal perceivable as sound by the user. Said first part comprises a receptacle adapted to receive an insert element, said insert element comprising protrusions configured for engaging with a recess of said first part by rotating the insert element relative to said first part.

An insertion device includes a stent and a plurality of sealing elements where each sealing element is operatively rotationally attached to the stent.

The present disclosure relates to compact hearing aids, components thereof, and support systems therefor, as well as methods of insertion and removal thereof. The compact hearing aids generally include a sensor, such as a microphone, an actuation mass, an energy source for providing power to the compact hearing aid, a processor, and an actuator enclosed in a housing that is designed to be inserted through the tympanic membrane during a minimally-invasive outpatient procedure. In operation, the microphone receives sound waves and converts the sound waves into electrical signals. A processor then modifies the electrical signals and provides the electrical signals to the actuator. The actuator converts the electrical signals into mechanical motion, which actuates the actuation mass to modulate the velocity or the position of the tympanic membrane.

Disclosed by the present invention are a communication control method, device and system, a charging box and a wireless earpiece, the method comprising: when charging a first wireless earpiece by means of two power pins, the charging box obtains first data to be sent if communication with the first wireless earpiece is needed; and according to the first data to be sent, the charging box controls the output voltages of the two power pins to be correspondingly exchanged, so that the first wireless earpiece switches according to the output voltage of a corresponding power pin so as to obtain the first data to be sent during the charging process. In the present method, the charging box controls the output voltages of the two power pins to be correspondingly exchanged according to the first data to be sent, so that the wireless earpiece may obtain the first data to be sent according to the switching of the charging voltages when using the switchable charging voltages of the two power pins to perform charging. Therefore, the wireless earpiece uses the two pins used for charging to communicate with the charging box during the charging process, thereby reducing the setup cost and taking both a small size and aesthetic appearance into account.

Hearing devices, configured to fit within the ear canal, having a hearing device core defining an exterior surface with a medial end and a medial corner, and including a battery, a microphone and a receiver, at least one seal, defining a seal compliance, carried on the hearing device core, and a medial bumper, defining a medial bumper compliance that is greater than the seal compliance, carried on the hearing device core.
