摘要： The systems and methods described herein relate to, among other things, a transducer capable of producing acoustic and tactile stimulation. The transducer includes a rigid mass element disposed on the diaphragm of a speaker. The mass element may optionally be removable and may have a mass selected such that the resonant frequency of the transducer falls within the range of frequencies present in an input electrical audio signal. The systems and methods advantageously benefits from both the fidelity and audio performance of a full-range speaker while simultaneously producing high-fidelity, adjustable and palpable haptic vibrations.

摘要： A postprocessor mixes audio signals for an LSch and an RSch indicating virtual surround sounds generated by a virtual surround processing unit with audio signals of an Rch, an Lch, and a Cch, performs a high-pass filter process, and then outputs the processed audio signals as audio signals for an Rsp and an Lsp which are main speakers. Further, the postprocessor performs phase inversion on the audio signals for the LSch and the RSch indicating the virtual surround sounds generated by the virtual surround processing unit, mixes the processed audio signals with audio signals of the Rch, the Lch, the Cch, and an LFEch, performs a low-pass filter process on the mixed signals, and then outputs the processed audio signals as audio signals for an SW which is a subwoofer. Thus, in a sound field realized by a virtual surround system, an influence of the sounds emitted from the subwoofer on localization of sounds of channels of virtual speakers is reduced.

摘要： A depth processing system can employ stereo speakers to achieve immersive effects. The depth processing system can advantageously manipulate phase and/or amplitude information to render audio along a listener's median plane, thereby rendering audio along varying depths. In one embodiment, the depth processing system analyzes left and right stereo input signals to infer depth, which may change over time. The depth processing system can then vary the phase and/or amplitude decorrelation between the audio signals over time to enhance the sense of depth already present in the audio signals, thereby creating an immersive depth effect.

摘要： To propose an audio control system in that even if it has a thin center speaker, low sounds can be felt to be heard from the center speaker. A low frequency signal in a center channel audio signal is delayed, and then the delayed signal is added to a right and a left channel audio signals, and they are transmitted to the corresponding left speaker and right speaker in the state where it is delayed from a high frequency signal in the above center channel audio signal. Thereby, a low sound based on the low frequency component in the center channel audio signal can be emitted as if it is emitted from a thin center speaker, by a phenomenon that sounds are heard as the position is deviated to the direction where there is the sound reached to the ears at first (HAAS effect).

摘要： A sound processing circuit for distributing low frequency signal components of multichannel audio signals. The sound processing circuit filters low frequency signal components from the digital audio signals of m (m ≤ n) specified channels using an exclusive channel having low frequency signals and n (n > 1) multiple independent channels, and outputs the filtered low frequency signal components as part of a low frequency signal channel. The sound processor circuit comprises m high-pass filters to receive digital audio signals from m of specified channels, and allows the signal components having a frequency higher than a cut-off frequency fc to pass; m first coefficient multipliers receive the digital audio signals of the m of specified channels and multiply the signals by a multiplication coefficient ai (0
