ELECTRONIC DEVICE FOR PROTECTION OF HEARING ORGANS WITH SWITCHED ELECTRICAL CONTACTS Russian patent published in 2020 - IPC H04R25/00 

FIELD: acoustics.

SUBSTANCE: invention relates to acoustics, in particular to hearing protection devices with switchable electric contacts. Proposed device comprises housing including battery and electronic unit. Electronic unit is powered by a battery, wherein the electronic unit comprises a processor controlled by the updatable software. Device comprises a first electrical contact, which is a grounding line; a second electrical contact which is a data programming line in a first state and which is a charge line with voltage in a second state; and a third electrical contact which is a synchronization line in a first state and which is a charge switching line in a second state. First, second and third electric contacts are accessible from the outside of the housing. Switch enclosed in the housing switches the second electrical contact between the first state and the second state.

EFFECT: technical result is reduced geometric dimensions and simplified manufacturing of device.
