Abstract: The disclosure provides a loudspeaker apparatus and a method of driving the acoustic transducers by predicting and compensating a physical phenomenon of acoustic pressure changes within an enclosure caused by at least one of the acoustic transducers. The loudspeaker apparatus includes an enclosure having an inner space, a first acoustic transducer, a second acoustic transducer, and a controller. The first and second acoustic transducers are mounted on the enclosure and share the same inner space of the enclosure, such as sound bar and the likes. For the operation of the loudspeaker apparatus, the controller applies an algorithm or mathematical model (e.g., transfer function) to an audio signal received from an external source, so that the sound respectively outputted by the first and second acoustic transducers sharing the same inner space may be compensated as if the first and second acoustic transducers are individually mounted on its own enclosure.

Abstract: A wearable electronic apparatus, a computer-implement operating method for the same, and an electronic system are provided. The method includes receiving a sound, and correspondingly generating a plurality of audio data according to the received sound; determining a relative direction and a relative location of the sound source and the wearable electronic apparatus, and an intensity level of the sound; generating a computer-generated visual content corresponding to the sound according to the relative direction, the intensity level of the sound, and the relative location; and displaying the generated computer-generated visual content corresponding to the sound on a transparent lens of the display device of the wearable electronic apparatus.

Abstract: A sound recording module including a sound-collecting space, a sound wave inlet, and a sound-receiving element is provided. The sound-collecting space at least has a reflecting zone. The reflecting area is adjacent to a first sound wave gathering zone and a second sound gathering zone, respectively. The first sound wave gathering zone appears in form of a hand web and defines a sound-receiving element fixing portion in the deepest position of the first sound gathering zone. The sound wave inlet is correspondingly formed on at least part of a periphery of the second sound gathering zone. The sound-receiving element is disposed at the sound-receiving element fixing portion of the first sound gathering zone. The sound-receiving element is configured to record a sound entering the sound-collecting space.

Abstract: A directional sound recording module including a sound-receiving case, a plurality of sound inlet apertures, and a sound-receiving element is provided. The sound-receiving case encircles to form a chamber. A sound inlet opening and a fixing end are respectively formed at two opposite sides of the chamber. The sound inlet opening and the fixing end are communicated with each other. The sound inlet apertures are disposed on a surface of the sound-receiving case and corresponding to the chamber. An extending direction of the sound inlet apertures is perpendicular to the sound inlet opening of the sound-receiving case. The sound-receiving element is disposed at the fixing end of the sound-receiving case. The sound-receiving element is configured to record a sound entering the chamber from the sound inlet opening and the sound inlet apertures.

Abstract: An audio signal processing apparatus configured to process a plurality of audio signals of a shared-volume stereo system is provided. The audio signal processing apparatus includes a plurality of signal processing channels. The signal processing channels are configured to filter the audio signals to obtain high-frequency components and low-frequency components. The signal processing channels perform a signal processing operation on the low-frequency components to generate a low-frequency modulation signal. The signal processing channels sum up the high-frequency components and the low-frequency modulation signal to reproduce a plurality of audio reproduction signals. The signal processing channels drive loudspeakers of the shared-volume stereo system according to the audio reproduction signals. Furthermore, an audio signal processing method is also provided.
