Abstract: A speaker includes a shell, a diaphragm, and a sliding connection portion. The shell includes a cavity. The diaphragm is accommodated within the cavity and separates the cavity to form at least two sub-cavities. The diaphragm is driven by an electrical signal to vibrate to generate sound. The sliding connection portion is configured to connect an edge of the diaphragm to an inner wall of the cavity. The sliding connection portion allows the edge of the diaphragm to slide relative to the inner wall of the shell. Therefore, the diaphragm can move (slide) relative to the inner wall of the shell. In other words, the diaphragm can make a piston-like movement relative to the inner wall of the shell, which allows the diaphragm to generate a greater displacement, push more air, and thereby improving the performance of the speaker, especially the sensitivity of the speaker at a low frequency range.

Abstract: Multi-player co-located AR experiences are augmented by assigning characters and costumes to respective participants (a.k.a. “users” of AR-enabled mobile devices) in multi-player AR sessions for storytelling, play acting, and the like. Body tracking technology and augmented reality (AR) software are used to decorate the bodies of the co-located participants with virtual costumes within the context of the multi-player co-located AR experiences. Tracked bodies are distinguished to determine which body belongs to which user and hence which virtual costume belongs to which tracked body so that corresponding costumes may be assigned for display in augmented reality. A host-guest mechanism is used for networked assignment of characters and corresponding costumes in the co-located multi-player AR session. Body tracking technology is used to move the costume with the body as movement of the assigned body is detected.
