A speaker enhancer for a wireless communication device includes an acoustic chamber forming section that, when the speaker enhancer is mounted to a rear of the wireless communication device, forms a sealed acoustic enclosure along the rear of the wireless communication device; and a speaker engagement section that, when the speaker enhancer is mounted to the rear of the wireless communication device, sealingly engages the rear of the wireless communication device and communicates the rearward-facing, rear-mounted speaker with the sealed acoustic enclosure. In use, rearwardly directed sound emitted from a rearward-facing, rear-mounted speaker travels through the speaker engagement section to the sealed acoustic enclosure, and primary sound from the speaker is emitted through sound leaks in the wireless communication device.
