  • Patent number: 12075208
    Abstract: A loudspeaker system (700 or 800) and method for tuning ported loudspeakers and reducing unwanted acoustic resonances provides reduced port noise, eliminates undesired port resonances and improves the accuracy and fidelity of reproduced sound in a loudspeaker system of relatively high efficiency with an enclosure including an Eigen Tone Filter structure (“ETF”) comprising a pipe or set of pipes 720, 820 placed inside a loudspeaker vent to absorb the “open pipe” acoustic resonance of the vent. The open-pipe resonance is unwanted and interferes with the midrange performance of the loudspeaker, when in use, if not corrected.

  • Patent number: 12051431
    Abstract: An audio similarity evaluator obtains envelope signals for a plurality of frequency ranges on the basis of an input audio signal. The audio similarity evaluator is configured to obtain a modulation information associated with the envelope signals for a plurality of modulation frequency ranges, wherein the modulation information describes the modulation of the envelope signals. The audio similarity evaluator is configured to compare the obtained modulation information with a reference modulation information associated with a reference audio signal, in order to obtain an information about a similarity between the input audio signal and the reference audio signal. An audio encoder uses such an audio similarity evaluator. Another audio similarity evaluator uses a neural net trained using the audio similarity evaluator.

  • Patent number: 11895475
    Abstract: A rear side of a vibration part of a speaker is covered by a cover member, and a duct is provided at the cover member. The cover member has a recessed portion, and an air flow path is formed inside the recessed portion. A circuit part is mounted on an outer surface of the cover member, and a heat sink provided in the air flow path is connected to the circuit part to allow heat conduction. Due to vibration of the vibration part, an airflow in the air flow path is accelerated and thus the effect of dissipating heat from the heat sink is increased.
