LOUDSPEAKER - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240048893 titled 'LOUDSPEAKER

Simplified Explanation

The abstract describes a loudspeaker that consists of a driver diaphragm, an enclosure, and an outlet. The driver diaphragm generates acoustic waves, while the enclosure includes an upper wall facing the driver diaphragm and a side wall connecting the upper wall to the diaphragm. The outlet is located on either the upper wall or the side wall and is responsible for outputting the acoustic waves. The driver diaphragm and the enclosure create a front volume chamber that communicates with the outlet, forming a front cavity. The inner surface of the upper wall has a protruding part near the outlet, and the distance from this position to the driver diaphragm is smaller than the distance from other parts of the inner surface to the driver diaphragm.

  • The loudspeaker includes a driver diaphragm, enclosure, and outlet.
  • The driver diaphragm produces acoustic waves.
  • The enclosure consists of an upper wall and a side wall connecting it to the driver diaphragm.
  • The outlet is located on the upper wall or side wall and outputs the acoustic waves.
  • The driver diaphragm and enclosure create a front volume chamber that communicates with the outlet.
  • The front volume chamber and outlet form a front cavity.
  • The inner surface of the upper wall has a protruding part near the outlet.
  • The distance from the protruding part to the driver diaphragm is smaller than the distance from other parts of the inner surface to the driver diaphragm.

Potential Applications:

  • Audio systems in vehicles, homes, and public spaces.
  • Public address systems in stadiums, auditoriums, and conference halls.
  • Entertainment systems in theaters and cinemas.
  • Communication devices such as telephones and intercoms.

Problems Solved:

  • Enhances the efficiency and performance of loudspeakers by optimizing the design of the enclosure and outlet.
  • Improves the quality and clarity of sound reproduction.
  • Reduces distortion and unwanted resonances.
  • Provides a more immersive audio experience.

Benefits:

  • Improved sound quality and fidelity.
  • Increased efficiency and output power.
  • Compact and space-saving design.
  • Enhanced user experience in various audio applications.
  • Reduction in manufacturing costs due to optimized design.


Original Abstract Submitted

a loudspeaker is disclosed, including a driver diaphragm, an enclosure and an outlet. the driver diaphragm is configured to produce acoustic waves. the enclosure includes an upper wall disposed opposite to the driver diaphragm and having an inner surface facing to the driver diaphragm, and a side wall connecting the upper wall to the driver diaphragm. the outlet is defined at the upper wall or the side wall, and configured to output the acoustic waves. the driver diaphragm and the enclosure define a front volume chamber communicating with the outlet. the front volume chamber and the outlet form a front cavity. the inner surface has a protruding part located close to the outlet, a distance from a position at the protruding part to the driver diaphragm is smaller than that from a position at other parts of the inner surface to the driver diaphragm.
