Abstract
The utility model discloses a mobile communication device and a sounding device thereof. The sounding device comprises a housing, a loudspeaker, and a vibrating diaphragm. The housing comprises a sound chamber and is equipped with a first sound hole and a second sound hole. Except the first sound hole and the second sound hole, other parts of the sound chamber form a sealed structure. The loudspeaker is hermetically disposed at the first sound hole while the vibrating diaphragm is hermetically disposed at the second sound hole. The sound chamber part communicating with the loudspeaker and the vibrating diaphragm is a rear sound chamber. A diaphragm in the loudspeaker vibrates up and down to compress the air in the rear sound chamber so as to drive the independent vibrating diaphragm disposed at the second sound hole to vibrate up and down. Therefore, effective vibrating area is doubled. As a result, low frequency can be compensated while low frequency effects are lifted. In addition, a purpose of increasing volume (sound pressure) can be achieved, being equivalent to a fact that one loudspeaker achieves the tone quality effects of two loudspeakers.
