PROBLEM TO BE SOLVED: To provide a speaker device capable of preventing an unwanted sound from being generated, and a damping unit.SOLUTION: The speaker device comprises a first vibrator, a first drive part, a second vibrator, a second drive part and a support part. The first vibrator is connected to a diaphragm which is vibrated to radiate a sound. The first drive part vibrates the diaphragm by vibrating the first vibrator in a reciprocal manner. The second vibrator is connected to a weight part. The second drive part is connected to a side reverse to the side where the first vibrator is provided in the first drive part, and vibrates the weight part by vibrating the second vibrator in a reciprocal manner on the same vibration axis as a vibration axis of the first vibrator. The support part supports a connection body to which the second vibrator and the weight part are connected, at two or more points in a vibration axis direction.SELECTED DRAWING: Figure 1 【課題】不要な音の発生を抑制することができるスピーカ装置および制振ユニットを提供すること。【解決手段】実施形態に係るスピーカ装置は、第１振動子と、第１駆動部と、第２振動子と、第２駆動部と、支持部とを備える。第１振動子は、振動することによって音を放射する振動板に連結される。第１駆動部は、第１振動子を往復振動させて振動板を振動させる。第２振動子は、重り部に連結される。第２駆動部は、第１駆動部における第１振動子が設けられる側とは逆側に連結され、第２振動子を第１振動子の振動軸と同一の振動軸上で往復振動させて重り部を振動させる。支持部は、第２振動子および重り部が連結される連結体を振動軸方向における２以上の箇所で支持する。【選択図】図１
