Most Android Speaker Cleaner apps utilize a sound wave cleaning method, emitting a series of high-pitched frequencies that the human ear can't hear. These ultrasonic waves vibrate and loosen particles like dust or grime that may be trapped inside the speaker grill. Some apps also guide you through a step-by-step process, while others automatically generate the sound frequencies once activated. It's important to note that the effectiveness of these apps can vary depending on the level of obstruction and the design of the speaker.
