摘要： An audio system determines latency for each client device of users participating in an artificial reality or augmented reality environment. The latency determined for a client device accounts for latency of a communication channel used by the client device to exchange data, as well as time for the client device to perform computational tasks. The audio system determines a distance in the artificial reality environment between a user's avatar and an audio source for audio data and adjusts one or more transfer functions for generating audio content for the user to account for effects of the latency determined for the user's client device on the audio content. In some embodiments, the audio system modifies a distance in the artificial reality environment between the user's avatar and the audio source to compensate for latency of the user's client device.

摘要： A speaker includes a housing having walls that define a cavity and a diaphragm covering the cavity and configured to vibrate under application of a magnetic field. The vibration produces sound waves. The walls are configured to deform under bending stress. The speaker is configured produce the sound waves both in an undeformed state and in a deformed state. Another speaker includes a flexible layer, a sensor configured to detect a curvature of the flexible layer, and a transducer disposed on and configured to vibrate the flexible layer. The vibrations of the flexible layer generate sound waves and output generated by the transducer is based on the curvature of the flexible layer.
