We can supply piezoelectric products including piezoelectric components, piezo single crystals, piezo subassemblies and select piezo based systems. 4mhz humidifier fuzed glass glaze nebulizer disc spray atomizing transducer piezo ceramic diffuser on soarpiezo's Store from DHgate. The beam pattern of a transducer can be determined by the active transducer area and shape, the ultrasound wavelength, and the sound velocity of the propagation medium. This circuit, enclosed in a small plastic box, can be placed into a bag or handbag.
