Abstract
Apparatuses that operate as both a public address speaker and a wireless access point (AP) for mounting to a ceiling or wall. The compact public address access points described herein may include an AP housing, enclosing a radio (e.g., a 3×3 MIMO radio) and antenna, that is coupled to a speaker assembly including a speaker, a conical acoustic reflector positioned between a front of the speaker and the housing of the AP, and an annular region comprising a concave inner wall facing the conical acoustic reflector. Although the AP is nested atop the front of the speaker, the speaker may produce high-quality sound with accurate voice reproduction without interfering with the operation of the wireless transmission of the AP. Methods of operating and installing these apparatuses are also described.
