There are several apps available on the Google Play Store that claim to clean Android speakers by emitting high-frequency sound waves. These frequencies are designed to dislodge dirt and debris trapped in the speaker mesh. The concept behind these apps is simple: sound waves vibrate the tiny particles inside the speaker, causing them to loosen and eventually fall out. While the effectiveness of these apps can vary depending on the level of buildup and the quality of the device’s speakers, many users find them helpful for minor cleaning tasks.
