  • Patent number: 12003917
    Abstract: The present invention provides a speaker, including: a housing body having an accommodation cavity with a first chamber and a second chamber; a first side wall and a second side wall enclosing the first chamber; a third side wall and a fourth side wall enclosing the second chamber; and a speaker unit including a connection part located in the first chamber and a sounding component connecting to the connection part. A distance between the first side wall and the second side wall is smaller than a distance between the third side wall and the fourth side wall. The speaker enables the connection part to be connected to the side wall of the housing body without the end of the connection part needing to exceed the end of the sounding component, which reduces the volume of the housing body and facilitates the miniaturized design of the speaker.

  • Patent number: 12003942
    Abstract: Electroacoustic drivers that can be utilized in loudspeaker systems that utilize drivers having a magnetic negative spring (MNS) (such as reluctance assist drivers (RAD) and permanent magnet crown (PMC) drivers). The electroacoustic drivers can be used at all audio frequencies, including subwoofer frequencies. The magnetic negative springs of the electroacoustic drivers can cancel, or partially cancel, the large pressure forces on a sound panel (of an audio speaker) so that substantial subwoofer notes can be efficiently and cost effectively produced in small/portable speakers. The electroacoustic drivers can include a stabilizing/centering mechanism to overcome the destabilizing forces of a MNS that are too large for a voice coil alone to produce.

  • Patent number: 12003930
    Abstract: A method and device for detecting acoustic feedback events with an artificial neural network in an in-ear earbud audio system that allows, by user interaction, playback of a recorded and processed signal from an environment-recording microphone by an in-ear speaker that faces or is at least acoustically coupled with the ear canal such that sound played by the speaker enters the ear canal. The audio system employs an acoustic seal that acoustically separates the speaker from the microphone, but due to external factors, the acoustical separation may not be adequate, thereby forming acoustic feedback paths. The neural network facilitates a binary classification of the time-wise segmented microphone signal, which is used to stop playback by the in-ear speaker if a feedback event is detected to protect the hearing of the user. Detection of a feedback event triggers an audible or wireless notification to be delivered to the user.

  • Patent number: 12003916
    Abstract: A pair of headphones may include first and second ear cups that each contain one or more speakers. The speakers may emit audio through a sound-permeable warp knit spacer fabric that is coupled to each ear cup. The warp knit spacer fabric may include inner and outer fabric layers joined by a spacer layer. The outer fabric layer may have first and second regions with different fabric densities. The first region with the greater fabric density may be used to form a label such as an R-shape or L-shape to indicate which ear cup should cover the user's right ear and which ear cup should cover the user's left ear. The denser first region may have diamond-shaped openings of a first size and the less dense second region may have diamond-shaped openings of a second size that is greater than the first size.
