  • Patent number: 10433049
    Abstract: A sound-reproducing device has a DSP and a ?Com performing a predetermined calculation to an input signal, and an AMP amplifying the calculated signal and outputting the signal to a speaker unit. The DSP and the ?Com cuts a part of a reverse characteristic of a frequency characteristic of the speaker unit in a low frequency, and superimposes the reverse characteristic on the input signal. The sound-reproducing device can overcome a shortage of low sound during reproduction of low to medium volume in the speaker unit having a relatively small diameter, and can keep reproduction sound quality without loss of the reproduction sound quality during reproduction of large volume.

  • Patent number: 10412482
    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.

  • Patent number: 10375481
    Abstract: A MEMS capacitive transducer with increased robustness and resilience to acoustic shock. The transducer structure includes a flexible membrane supported between a first volume and a second volume, and at least one variable vent structure in communication with at least one of the first and second volumes. The variable vent structure includes at least one moveable portion which is moveable in response to a pressure differential across the moveable portion so as to vary the size of a flow path through the vent structure. The variable vent may be formed through the membrane and the moveable portion may be a part of the membrane, defined by one or more channels, that is deflectable away from the surface of the membrane. The variable vent is preferably closed in the normal range of pressure differentials but opens at high pressure differentials to provide more rapid equalisation of the air volumes above and below the membrane.
