DIGITAL HEARING AID WITH BUILT-IN ACCUMULATOR Russian patent published in 2022 - IPC A61F11/04 H04R25/02 A61B5/12 

FIELD: medicine; otolaryngology.

SUBSTANCE: invention can be used as a digital hearing aid with a built-in battery, comprising a housing equipped with covers on both sides, an ear element, a switching device, a gain control, block diagram located in the housing, which contains a microphone, an amplifier, an accumulator, which are interconnected. Body is made integral with the ear element, in which the acoustic output is placed. Each of the covers is fixed by means of at least four screws, housing is equipped with a gain control, a program switching button, a programming connector, a front microphone input, a rear microphone input, the block diagram contains an MBS_300 module, in which there is an additional memory microcircuit interconnected with audio DSP by direct and feedback. MBS_300 module is connected to a front microphone, a rear microphone, an induction coil, an audio input, a listening program switch, an oscillator microcircuit, Reed switch, bus programming connector 12C with direct and feedback is interconnected with MBS_300 module, the latter is connected with telephone. In addition, the battery charging connector is connected to a lithium-polymer battery, a voltage converter, which provides power to the front and rear microphones, the MBS_300 module and the oscillator microcircuit.

EFFECT: enabling the possibility of increasing the efficiency of digital signal processing due to compliance with sound processing algorithms, for the audiogram of the owner of the hearing aid, availability of additional permanent rewritable memory, providing high output sound pressure and high acoustic gain, high level of algorithms for processing acoustic signals and controlling operating modes.
