    • Vibration is prevented from being transmitted via a common ink chamber or a fixed substrate. A porous member is disposed between the common ink chamber and a pressure generation chamber so that a discharge liquid passes through the interior of the porous member to move from the common ink chamber to the pressure generation chamber. Vibration generated in one pressure generation chamber is attenuated through the porous member when the vibration is transmitted to another pressure generation chamber via the common ink chamber; and thus, no cross-talk is generated. Furthermore, when piezoelectric vibrators having different lengths are mounted on the same fixed substrate and have the resonance frequencies different from each other, vibration is not transmitted to another pressure generation chamber via the fixed substrate and the piezoelectric vibrator; and therefore, the cross-talk is much less likely to be generated.
    • 防止振动通过公共墨水室或固定基板传输。 多孔构件设置在公共墨室和压力产生室之间,使得排出液体通过多孔构件的内部,以从共用墨室移动到压力产生室。 当振动通过公共墨水室传递到另一个压力产生室时,在一个压力产生室中产生的振动通过多孔构件衰减; 因此不产生串扰。 此外,当具有不同长度的压电振动器安装在相同的固定基板上并且谐振频率彼此不同时,振动不会经由固定基板和压电振动器传递到另一个压力产生室; 因此,串扰不太可能产生。
