RECEIVER WITH INDUCTION LOOP Russian patent published in 2019 - IPC A61F11/04 

FIELD: medicine.

SUBSTANCE: invention relates to means that satisfy human vital needs, in particular to methods and devices providing people with hearing defects the possibility of replacing direct auditory perception with another type of perception, in particular, to means of changing tone-sound signals. Receiver with an induction loop comprises a loop cable connected to the signal conversion device in the form of equipped with supports on the lower face of the housing, in which there is a structural circuit containing a microcontroller, amplifiers, a power supply. Housing is made in the form of rectangular prism, in cross section having trapezoid, with possibility of horizontal arrangement. Housing cover is equipped with light-emitting diode tape located along its perimeter. On the back edge of the housing there are connectors for loop cable, power supply, line input 1, line input 2, microphone input with connecting cable, S/PDIF connection cable. On the side face of the housing there are adjustment elements: input into the menu in form of a button, volume, low frequency and high frequency. On lower edge of housing there are supports, U-shaped groove, sockets for attachment of loop cable. In the central part of the lower edge of the housing there are ventilation holes and holes for attachment of the upper cover. Structural microcircuit is equipped with power units and menu button. Microcontroller is connected to the LED unit by means of the LEDs control unit, interacts with the "Loop" output through the operational amplifier and power amplifier, is connected to a tone unit equipped with high, low frequency and volume controllers. "Mute" unit of the structural microcircuit is connected through the operational amplifier to the equalizer and the microcontroller. Microcircuit is equipped with an antenna and a radio module.

EFFECT: higher quality of sound when listening to the interlocutor's voice without distortion of external acoustic conditions, preservation of sound intensity at its multiple reflections, use of induction loop without intervention of technicians.
