Zusammenfassung:A device with external diaphragm for acoustic cleaning and air purification is provided. The device comprises a housing with a first opening at a top for receiving one or more acoustic wave generating devices each with a diaphragm attached to a coil; and one or more external diaphragm each covering and sealing the diaphragm attached to the coil to facilitated in protecting the acoustic wave generating device as impurities or materials deposit and accumulate on the external diaphragm instead of the diaphragm of the acoustic wave generating device, and easy cleaning as only the external diaphragm needs to be cleaned, which also avoids damage to the diaphragm of the acoustic wave generating device during cleaning.
