SECOND DEGREE OF FREEDOM SPEAKER FOR CAVITY RESONANCE CANCELLATION - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240098404 titled 'SECOND DEGREE OF FREEDOM SPEAKER FOR CAVITY RESONANCE CANCELLATION
Simplified Explanation
The patent application describes a speaker with a membrane that has different breakup frequencies in various regions to mitigate cavity resonance and distortion in frequency response.
- The speaker produces acoustic frequencies within a housing.
- The acoustic frequencies are outputted to a port.
- The frequencies travel through a cavity to the port.
- The port may have a cavity resonance that amplifies certain frequencies.
- This affects the frequency sensitivity of the speaker.
- The speaker includes a membrane with regions having different breakup frequencies.
- One region is tuned to break up at a desired bandwidth of the speaker.
- Another region is tuned to break up at the cavity resonance.
- This mitigates the distortion on frequency response due to the cavity resonance.
Potential Applications
The technology could be applied in:
- High-quality audio systems
- Home theater systems
- Professional sound equipment
Problems Solved
The technology addresses issues such as:
- Distortion in frequency response
- Cavity resonance affecting frequency sensitivity
Benefits
The benefits of this technology include:
- Improved sound quality
- Enhanced frequency response
- Reduced distortion
Potential Commercial Applications
The technology could be commercially used in:
- Speaker manufacturing industry
- Audio equipment market
- Entertainment industry
Possible Prior Art
One possible prior art could be the use of different materials in speaker membranes to control breakup frequencies.
Unanswered Questions
How does the membrane with different breakup frequencies affect the overall performance of the speaker?
The article does not delve into the specific impact of the membrane on the speaker's performance as a whole.
Are there any limitations to the mitigation of cavity resonance using this technology?
The article does not discuss any potential limitations or drawbacks of using this technology to mitigate cavity resonance.
