Description: Speaker inverted holes, also called sound tubes and air holes, are often used in inverted speakers, mainly to overwhelm the airflow sound of the speaker vibration in the box and overlap the sound pressure radiated in front of the speaker to produce a bass effect. The principle is: when the anti-phase sound waves radiated from the paper cone into the box, through the action of the box, and then radiated outward through the inverted tube, some of the sound waves of the lower limit frequency can be close to the phase of the same frequency sound waves radiated in front of the paper cone. As a result, the radiation efficiency of the speaker can be improved, thereby extending the low-frequency response. This structure can significantly enhance the low-frequency radiation intensity, increase the volume, and improve the efficiency of the speaker. In layman's terms, it can increase the volume of the bass without increasing the power of the speaker itself.
