    • An inkjet print head (10) includes one or more laser sources (12). Each laser source (12) is actuable to emit laser radiation and each laser source is associated with one or more ink chambers (18). Each ink chamber (18) includes a nozzle aperture (20) through which ink is dispensed and is arranged to, in use, communicate with an ink supply. Each chamber has a membrane (16) arranged to contact the ink in the ink chamber, the membrane being responsive to laser radiation from an associated laser source to produce an acoustic emission capable of displacing ink from the chamber.
    • 喷墨打印头(10)包括一个或多个激光源(12)。 每个激光源(12)可致动以发射激光辐射,并且每个激光源与一个或多个墨室(18)相关联。 每个墨水室(18)包括喷嘴孔(20),油墨通过该喷嘴孔(20)被分配并且在使用中被布置成与墨水供应连通。 每个室具有布置成接触墨室中的墨的膜(16),所述膜响应于来自相关联的激光源的激光辐射,以产生能够从腔室移位墨的声发射。
