FIELD: electric engineering.
SUBSTANCE: invention is related to the field of electronics and may be used in design of electric musical instruments, which convert mechanical energy of strings vibration into electric signals, for instance electric guitars, electric violins, electric pianos, etc. Active electromagnet sound receiver consists of two flat pole cores 5 and 7, which are attached perpendicularly to opposite poles of permanent magnet 6, on which the first 1, second 2, third 3 and fourth 4 signal coils are installed, of power supply source 8, displacement circuit 9 and transistor 10. Coils 1 and 2 are installed in core 5, coils 3 and 4 - on core 7.
EFFECT: invention provides for higher validity of useful sound signal transfer in wide range of frequencies, higher noise immunity and stability of working characteristics.
