FIELD: radio-engineering.
SUBSTANCE: invention refers to radio-engineering, and can be used when manufacturing mobile communication devices. Dynamic module includes a dynamic housing forming a chamber, and a dynamic having front surface and rear surface. Dynamic is located in the housing so that its front surface of dynamic opens from the dynamic housing, and its rear surface is located in the chamber, which allows the sound generated from rear surface to resonate in the chamber. At least one sound wire is connected to the chamber, and has end part opened inward the housing of terminal. Mutual interference between sound generated from the front side of the part radiating the sound and the sound radiated from its rear side can be decreased so that characteristic of mid-frequency and low-frequency sound can be improved.
EFFECT: improving low-frequency sound characteristic Mobile communication device includes housing of terminal, dynamic module located therein, and at least one sound wire.
