A button apparatus with a speaker ( 100 ) has a frame ( 104 ), a speaker ( 108 ), a flexible PCB ( 110 ), a metal dome ( 114 ), a rubber layer ( 116 ), and an operating button ( 120,124 ). The frame has a cavity ( 106 ) and the speaker is securely received in the cavity. The flexible PCB is located on the frame. The metal dome is located on the flexible PCB, and adapted to electrically connect with the flexible PCB. The rubber layer is located on the flexible PCB. The rubber layer has a protrusion ( 118 ) to press the metal dome so that the metal dome is electrically coupling to the flexible PCB. The operating button is located on the rubber layer. The button is adapted to press the protrusion, which in turn presses the metal dome.
