Speaker with Single Driver Force Cancellation - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240292136 titled 'Speaker with Single Driver Force Cancellation

The abstract describes a speaker system with a unique design that includes multiple moving masses and passive radiators to cancel out forces generated during operation.

  • The speaker system consists of a first moving mass, such as a diaphragm, coupled to a fixed frame via a first non-rigid suspension.
  • A second moving mass, like a motor assembly, is also coupled to the fixed frame.
  • A passive radiator is coupled to the fixed frame via a second non-rigid suspension.
  • The motor assembly and diaphragm move in response to an audio drive signal, generating pressure and a force on the fixed frame.
  • The fixed frame is designed to shunt the pressure to the passive radiator, which generates a force that cancels out at least a portion of the initial force on the fixed frame.

Potential Applications: - High-end audio systems - Home theater systems - Professional sound reinforcement equipment

Problems Solved: - Minimizing vibrations and distortions in speaker systems - Improving sound quality and accuracy

Benefits: - Enhanced audio performance - Reduced unwanted vibrations - Improved overall listening experience

Commercial Applications: Title: Advanced Speaker Systems for Premium Audio Experiences This technology can be used in high-end audio equipment for home entertainment, professional sound systems, and automotive audio systems. The market implications include catering to audiophiles and enthusiasts looking for superior sound quality.

Questions about the technology: 1. How does this speaker system compare to traditional speaker designs in terms of performance? - The innovative design of this speaker system aims to reduce vibrations and distortions, leading to improved sound quality compared to traditional designs. 2. What are the potential cost implications of implementing this technology in commercial audio products? - The cost implications may vary depending on the complexity of the system and the materials used, but the benefits in terms of audio performance may justify the investment.


Original Abstract Submitted

a speaker system can include a first moving mass, such as a diaphragm, coupled to a fixed frame via a first non-rigid suspension and coupled to a voice coil. the speaker system can include a second moving mass, such as a motor assembly, coupled to the fixed frame. the speaker system can include a passive radiator coupled to the fixed frame via a second non-rigid suspension. the motor assembly and the diaphragm are configured to move in response to an audio drive signal, causing a pressure to be generated and a first force to be generated on the fixed frame. the fixed frame is configured so that the pressure is shunted to the first passive radiator that is configured to generate a second force in response to the shunted pressure causing a second force on the fixed frame that cancels at least a portion of the first force.
