Speaker with Single Driver Force Cancellation - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240236556 titled 'Speaker with Single Driver Force Cancellation
Simplified Explanation: The speaker system described in the patent application consists of a fixed frame, a voice coil, and two moving masses with different suspensions. The diaphragm, attached to the first moving mass, responds to an audio drive signal applied through the motor assembly, which exerts a force on the voice coil. The secondary suspension cancels out the force on the motor assembly caused by the audio drive signal, ensuring smooth operation.
- The speaker system includes a fixed frame, voice coil, and two moving masses.
- The diaphragm is attached to the first moving mass and responds to an audio drive signal.
- The motor assembly applies a force on the voice coil to produce sound.
- The secondary suspension cancels out the force on the motor assembly caused by the audio drive signal.
- This design ensures efficient and precise movement of the diaphragm for accurate sound reproduction.
Potential Applications: 1. High-quality audio systems for home entertainment. 2. Professional sound systems for concerts and events. 3. Automotive audio systems for immersive driving experiences.
Problems Solved: 1. Ensures smooth and accurate movement of the diaphragm. 2. Cancels out unwanted forces on the motor assembly. 3. Improves overall sound quality and performance of the speaker system.
Benefits: 1. Enhanced audio clarity and fidelity. 2. Reduced distortion and interference. 3. Improved efficiency and reliability of the speaker system.
Commercial Applications: Title: Advanced Speaker Systems for Premium Audio Experiences This technology can be used in high-end audio equipment for home theaters, concert venues, and automotive sound systems. The precise movement and cancellation of unwanted forces result in superior sound quality and performance, appealing to audiophiles and professionals in the audio industry.
Questions about Speaker Systems: 1. How does the secondary suspension cancel out the force on the motor assembly?
- The secondary suspension is designed to counteract the force exerted on the motor assembly by the audio drive signal, ensuring smooth operation of the speaker system.
2. What are the potential applications of this advanced speaker system technology?
- This technology can be used in various audio systems, including home entertainment, professional sound setups, and automotive audio systems, to enhance audio quality and performance.
Original Abstract Submitted
a speaker system includes a fixed frame, a voice coil and a first moving mass that includes a diaphragm. the first moving mass is coupled to the fixed frame via a non-rigid primary suspension and coupled to the voice coil. the speaker system further includes a second moving mass that includes a motor assembly and is coupled to the fixed frame via a non-rigid secondary suspension. the diaphragm is configured to move in response to an audio drive signal, applied via the motor assembly, which asserts a force on the voice coil. a first force, on the motor assembly caused by applying the audio drive signal and pushing the voice coil, is canceled by a second force on the moving motor assembly from the non-rigid secondary suspension.
