An integrated sounding device is disclosed. The integrated sounding device includes a housing having a sound outlet, a speaker unit and a fixing member. The speaker unit includes a diaphragm having a first suspension, a second suspension and a dome. The fixing member connects an inner fixing part of the second suspension and the housing. The dome includes a first side close to the sound outlet and a second side far away from the sound outlet. The two sides are respectively arranged at opposite sides of the fixing member. The first side has a first groove, and the second side has a second groove. A filler for balancing amplitudes of the two sides is provided in the first groove. The integrated sounding device can balance the acoustic mass of the vibration system, so as to balance the vibrations of the vibration system and eliminate the sound distortions.
