Abstract: A method and device for automatically increasing the spectral bandwidth of an audio signal including generating a “mapping” (or “prediction”) matrix based on the analysis of a reference wideband signal and a reference narrowband signal, the mapping matrix being a transformation matrix to predict high frequency energy from a low frequency energy envelope, generating an energy envelope analysis of an input narrowband audio signal, generating a resynthesized noise signal by processing a random noise signal with the mapping matrix and the envelope analysis, high-pass filtering the resynthesized noise signal, and summing the high-pass filtered resynthesized noise signal with the input narrowband audio signal. Other embodiments are disclosed.

Abstract: An integrated audio-visual system is disclosed for delivering an event to one or more spectators. The integrated audio-visual system includes one or more loudspeakers that are positioned behind one or more visual displays to be effectively behind the one or more visual displays to be shielded from the field of view of the one or more spectators. The one or more visual displays are specially designed and manufactured to allow sound associated with the event to propagate from the one or more loudspeakers with minimal acoustical distortion and/or minimum acoustical vibration while presenting a visual representation of the event to the one or more spectators. Moreover, the one or more loudspeakers and the one or more visual displays are situated to be a predetermined displacement from each other to further minimize acoustical distortion.

Abstract: A head-mounted device and a retractable headband are provided. The head-mounted device includes a host, a retractable headband, and an earphone. The host has a first connection part and a second connection part located on two opposite sides. The retractable headband has an earphone connection part and a first connection end and a second connection end located on two opposite sides. The first connection end is connected to the first connection part. The second connection end is connected to the second connection part. When the retractable headband is elongated by an elongation amount, a change in a distance between the earphone connection part and the first connection end is less than half of the elongation amount. The earphone is connected to the earphone connection part.
