Stereo Earphone Patents (Class 381/309)
  • Patent number: 10375506
    Abstract: Sound is produced through headphones in a manner that improves user experience and increases safety. In some circumstances, such as when the user is moving during exercise, commuting, etc., an audio safety spatialization mode of the headphones is automatically activated. In this mode, sound is spatialized such that when the user turns his head, the sound appears to be generated from a same position in space as before the user turned his head. If the user's head remains in the turned position, the spatialized sound will return to an initialized position with respect to the user's head.

  • Patent number: 9794715
    Abstract: A system can include a hardware processor that can receive left and right audio signals and process the left and right audio signals to generate three or more processed audio signals. The three or more processed audio signals can include a left audio signal, a right audio signal, and a center audio signal. The processor can also filter each of the left and right audio signals with one or more first virtualization filters to produce filtered left and right signals. The processor can also filter a portion of the center audio signal with a second virtualization filter to produce a filtered center signal. Further, the processor can combine the filtered left signal, filtered right signal, and filtered center signal to produce left and right output signals and output the filtered left and right output signals.

  • Patent number: 9794676
    Abstract: A headphone that has a support structure that is adapted to sit on a head or upper torso of a user, a first acoustic driver carried by the support structure such that the first acoustic driver is located off of an ear of the user, wherein the first acoustic driver has front and rear sides and sound is radiated from both sides of the first acoustic driver, and a structure that defines a first acoustic chamber on the front side of the first acoustic driver and with at least one opening therein, and a second acoustic chamber on the rear side of the first acoustic driver and with at least one opening therein. At low frequencies a polar pattern of the first acoustic driver behaves approximately like a dipole, and at high frequencies a polar pattern of the first acoustic driver exhibits a higher order directional pattern. A second acoustic driver can be included.

  • Patent number: 9769585
    Abstract: Methods and systems for positioning audio signals on virtual soundstages. The mobile device may include one or more orientation components that are used to generate orientation data that track directional changes that are used to position an audio signal on a virtual soundstage. A listener of the sound from the audio signal may be associated with the orientation data such that the positioning of the audio signal provides virtual acoustic presence on the virtual soundstage. The audio signal is received, the audio signal may be associated with a plurality audio channels. The orientation data for positioning the audio signal is also received. A position for the audio signal on the virtual soundstage is determined based in part on the orientation data. The audio signal is then positioned on the virtual soundstage.

  • Patent number: 9744459
    Abstract: An example game device includes a virtual camera, a localization calculation microphone, and a volume calculation microphone in a virtual space. The localization calculation microphone is provided at the location of the virtual camera, and the volume calculation microphone is located away from the virtual camera. The game device calculates a left-right position and a front-back position of a sound source as viewed from the localization calculation microphone. The game device also calculates the volume of a sound based on a distance between the volume calculation microphone and the sound source. The game device outputs the sound based on the calculated localized position and volume.

  • Patent number: 9693128
    Abstract: The present invention is characterized in that coupling units are placed on upper and lower ends of the body of a conventional earphone, one coupling unit of respective coupling units is coupled, the earphone cord is wound between the coupling units, and the other coupling unit is coupled, thereby binding the earphone cord. The present invention makes it possible to prevent the cord from being twisted while being contained after earphone binding and to use the cord ring, which is created in the binding process, to hold the earphone on the user's body or a portable device.

  • Patent number: 9641953
    Abstract: A sound spatialization, with the application of at least one transfer function with room effect to at least one sound signal. This application amounts to multiplying, in the spectral range, spectral components of the sound signal by the spectral components of a filter corresponding to the transfer function, each spectral component of the filter having a temporal evolution in a time-frequency representation. In particular, the spectral components of the filter are especially ignored, for the above-mentioned multiplications of components, beyond a threshold frequency and after at least a given instant in said time-frequency representation.

  • Patent number: 9602928
    Abstract: According to an embodiment, a speaker system includes filters, speakers, and a sound collection unit. Each of the filters filters a first signal to generate a second signal. The speakers are arranged so that transfer characteristics from the speakers to an evaluation point are different from each other. Each of the speakers converts the second signal generated by a corresponding one of the filters into a sound wave. The sound collection unit combines sound waves output from the speakers to generate a combined sound wave. The filters are formed so that a transfer characteristic from the first signal to an output signal matches a target transfer characteristic, the output signal indicating a sound pressure of the combined sound wave at the evaluation point.
