The present disclosure relates to a hearing instrument comprising a rechargeable battery source providing a battery supply voltage and a switched capacitor DC-DC converter comprising a DC input coupled to the battery supply voltage for converting the battery supply voltage into a higher or lower DC output voltage. The hearing instrument comprises at least one active circuit connected to the DC output voltage for energizing active components of the at least one active circuit.

An exemplary auditory prosthesis system includes an audio accessory configured to be external to a patient and that includes 1) a plurality of microphones that receive incoming audio and convert the incoming audio into a plurality of audio signals, 2) a first communication port that connects directly to a communication port of a body-worn sound processor apparatus by way of a first cable, 3) a second communication port that connects directly to a communication port of a headpiece by way of a second cable, and 4) a control module communicatively coupled to the plurality of microphones and the first and second communication ports and that generates a processed audio signal by processing the plurality of audio signals converted by the plurality of microphones from the incoming audio and provides the processed audio signal to the body-worn sound processor apparatus.

The hearing system comprises a finger ring and a hearing device body. The finger ring includes: a first short-distance wireless communication portion; a vibration output portion disposed at a position that contacts a finger to convert a voice signal, which is received by the first short-distance wireless communication portion, into a cartilage conduction vibration and outputs it; and a first power source portion that supplies power to the first short-distance wireless communication portion and the vibration output portion. The talk device body includes: a second short-distance wireless communication portion that communicates with the first short-distance wireless communication portion; a microphone; a voice signal output portion that makes the second short-distance wireless communication portion output the voice signal according to a voice captured by the microphone; and a second power source portion that supplies power to the second short-distance wireless communication portion, the microphone, and the voice signal output portion.

A system includes a mobile device that receives an audio signal from a microphone of the mobile device. The mobile device processes the audio signal via a neural network to obtain a speech-enhanced audio signal. The system includes an ear-wearable device comprising a data interface operable to communicate with the external data interface of the mobile device. The ear-wearable device includes an audio processing path coupled to the data interface and is operable to receive the speech-enhanced audio signal and reproduce the speech-enhanced audio in an ear of a user.

System and techniques for audio enhancement processing for both electronically delivered audio signals and ambient sound. Ambient sound processing includes audio enhancement processing of signals captured by ambient microphones communicatively coupled to an audio enhancement processing apparatus as well as media provided by a storage device. Audio enhancement processing is provided for a user utilizing an electronic device that is directly or indirectly communicatively coupled to accessory microphones.
