FIELD: physics, radio.
SUBSTANCE: field of the present invention application is its application in radio communication terminals. Transducer for sound reproduction is connected to printed circuit, has the shape of hollow cylinder, cylindrical wall of which forms two round sides opposite to each other, and is limited by flat front side and back side. Transducer also comprises at least one diaphragm for conversion of electric signals into acoustic waves and back, at that diaphragm represents round membrane, which is parallel to front and back sides of transducer, and limits two separate cavities in transducer, the first cavity limited from one side by transducer round side and from the other side by diaphragm and shaping front acoustic cavity, and the second cavity limited from one side by transducer round side and from the other side by diaphragm and shaping back acoustic cavity. Cylindrical wall of transducer comprises at least one opening.
EFFECT: improved quality of sound reproduction.
