Beschreibung
Zusammenfassung:	The invention discloses a PMUT array ultrasonic transducer which comprises a PCB substrate and a plurality of mutually independent PMUT array elements, the PCB substrate is provided with a plurality of patch areas arranged in an array mode, the PMUT array elements are detachably connected to the patch areas, and the PMUT array elements correspond to the patch areas in a one-to-one mode. The PMUT array elements in the PMUT array ultrasonic transducer provided by the invention are mutually independent and can be detached and replaced, and different PMUT array elements can be selected to be combined into the PMUT array ultrasonic transducer according to different ultrasonic wave transmitting and receiving requirements, so that multi-frequency and wide-bandwidth ultrasonic wave transmitting and receiving are realized; and the reusability and the adaptability of the PMUT array ultrasonic transducer are improved. 本发明公开了一种PMUT阵列超声换能器，其包括：PCB衬底和多个相互独立的PMUT阵元，所述PCB衬底上设有多个阵列排布的贴片区域，所述PMUT阵元可拆卸地接合于所述贴片区域，且所述PMUT阵元与所述贴片区
