LOUDSPEAKER FOR HEARING DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240031741 titled 'LOUDSPEAKER FOR HEARING DEVICE

Simplified Explanation

The abstract describes a loudspeaker for hearing devices that includes a diaphragm and a housing with a back volume and a front volume. The front volume is acoustically coupled to a sound port. The first magnet in the front volume faces an opposing surface of a second magnet in the back volume, with a gap separating the magnets and having the same magnetic polarity. An electrical coil assembly coupled to the diaphragm is movable in the gap between the magnets in response to an electrical audio signal.

  • The loudspeaker is designed for hearing devices and includes a diaphragm and a housing.
  • The housing has a back volume and a front volume, with the front volume acoustically coupled to a sound port.
  • The first magnet in the front volume faces an opposing surface of a second magnet in the back volume.
  • The magnets are separated by a gap and have the same magnetic polarity.
  • An electrical coil assembly coupled to the diaphragm is movable in the gap between the magnets.
  • The movement of the diaphragm and electrical coil assembly is in response to an electrical audio signal.

Potential applications of this technology:

  • Hearing aids: The loudspeaker can be used in hearing aids to provide improved sound quality and clarity.
  • Headphones: This technology can be applied to headphones, allowing for better audio reproduction and immersive listening experiences.
  • Communication devices: The loudspeaker can be integrated into communication devices such as smartphones or tablets, enhancing the audio output for clearer voice calls and multimedia playback.

Problems solved by this technology:

  • Improved sound quality: The design of the loudspeaker, with the acoustically coupled front volume and the magnetic arrangement, helps in producing high-quality sound.
  • Compact size: The use of a diaphragm and electrical coil assembly in a compact housing allows for the integration of this loudspeaker in small hearing devices or portable audio devices.

Benefits of this technology:

  • Enhanced audio experience: The loudspeaker provides improved sound quality, allowing users to enjoy clearer and more immersive audio.
  • Compact and portable: The design of the loudspeaker enables its integration into small and portable devices, making it convenient for users to carry and use.
  • Customizable: The loudspeaker can be tailored to specific hearing device requirements, allowing for personalized audio solutions.


Original Abstract Submitted

a loudspeaker for hearing devices including a diaphragm arranged in a housing to form a back volume and a front volume acoustically coupled to a sound port is disclosed. a surface of a first magnet in the front volume faces an opposing surface of a second magnet in the back volume, and the opposing surfaces of the magnets are separated by a gap and have the same magnetic polarity. an electrical coil assembly coupled to the diaphragm has a radial difference dimension to thickness dimension ratio greater than 1, wherein the diaphragm and the electrical coil assembly are movable in the gap between the magnets in response to an electrical audio signal applied to the electrical coil assembly.
