Abstract
A loudspeaker apparatus comprises a speaker unit and a front cover. The speaker unit generates acoustic wave according to an external electronic signal. The front cover located in front of the speaker unit includes a plurality of the elastic spacer and a diaphragm. The elastic spacer and the diaphragm form an enhance chamber, such that the acoustic wave generated by the speaker unit goes through the enhance chamber, and then drives the diaphragm to generate the acoustic wave again.
