We integrate Klippel technology to enhance product quality and optimize R&D processes. Klippel enables us to:
- Identify and resolve design flaws early in development.
- Improve manufacturing precision with real-time feedback.
- Deliver superior sound quality tailored to high-performance markets.
By integrating Klippel’s advanced tools into our workflow, Jazz Hipster ensures that every speaker we produce not only meets but redefines industry standards. This approach reflects our commitment to innovation and our drive to create world-class audio experiences.
Key Klippel Features: How Jazz Hipster Puts Them to Work
Transducer Parameters
Jazz Hipster leverages advanced Klippel testing technology to optimize speaker design and ensure superior quality. Here’s how we apply key transducer parameters in R&D and production.
Small Signal Lumped Parameters
Small signal parameters (e.g., resonance frequency fs, mechanical quality factor Qms, and stiffness Kms) describe a transducer’s linear performance at low amplitudes. These parameters are crucial for modeling the electrical and mechanical behavior of the speaker.
- Accurately determine Thiele-Small parameters for reliable performance prediction.
- Use laser-based measurements to detect visco-elastic effects (creep), improving low-frequency response.
- Optimize driver design for efficiency and consistency across production.
Electrical Impedance
Electrical impedance measures the relationship between voltage and current at the speaker terminals. It is fundamental for defining parameters such as nominal impedance and detecting inconsistencies in driver performance.
- Enables precise modeling of electrical components, minimizing distortion.
- Differentiates mechanical, electrical, and acoustic influences in transducers.
- Provides actionable insights for tuning performance in complex designs.
Transducer Nonlinearities (Curve Shape)
Nonlinearities, such as force factor Bl(x), compliance Cms(x), and inductance L(x), describe how a speaker’s performance changes at high amplitudes. These characteristics influence distortion, stability, and power handling.
- Identify and mitigate nonlinear distortion in early-stage design.
- Optimize voice coil and suspension performance for durability and clarity.
- Enable advanced simulation for predicting speaker behavior under stress.
Single-valued Nonlinear Parameters
Single-valued parameters (e.g., peak displacement Xmax, suspension asymmetry, and voice coil offset Xoffset) simplify data interpretation and provide clear thresholds for testing.
- Accelerate production validation with real-time quality checks.
- Automate end-of-line testing for consistency.
- Improve production efficiency by quickly identifying defective units.
Harmonic Distortion
Harmonic distortion is one of the most common issues in audio systems, resulting from nonlinearities in the transducer. Jazz Hipster utilizes advanced tools to measure and mitigate harmonic distortion, ensuring superior sound quality in every speaker.
Using Klippel’s advanced tools like TRF and DIS modules, we pinpoint and measure harmonic distortion during both development and production. This ensures that our speakers deliver sound that’s faithful to the original recording.
Intermodulation Distortion
Intermodulation distortion (IMD) occurs when multiple input tones interact to produce new frequencies, often disrupting audio clarity. This is particularly noticeable in complex signals, such as music or spoken word.
IMD arises when nonlinear systems generate sum and difference frequencies not present in the original signal. This effect can lead to phase modulations and audible roughness in high-frequency content.
Rub & Buzz
Rub & Buzz distortion stems from physical defects such as loose particles, misaligned voice coils, or structural resonances. These issues are often imperceptible during typical THD testing but have a significant impact on audio quality.
Maximum SPL
Achieving high SPL (Sound Pressure Level) without distortion is a hallmark of superior speaker design. Jazz Hipster balances loudness and clarity through rigorous testing.
At high volumes, speakers face challenges like thermal compression, mechanical excursion limits, and increased harmonic distortion. Proper testing ensures these factors are managed effectively.
DC Displacement
DC displacement results from asymmetries in stiffness, force factor, or inductance characteristics. Left unchecked, it can degrade performance and durability.
When suspension or motor components are unevenly balanced, the voice coil shifts away from its resting position, producing dynamic offsets that affect sound quality.
Mechanical Vibration Analysis
At Jazz Hipster, understanding and optimizing mechanical vibration is critical to ensuring superior sound quality. By leveraging Klippel’s state-of-the-art systems, we analyze every aspect of voice coil displacement, vibration patterns, and modal behavior. Here’s how we do it:
Voice Coil Displacement
The movement of the voice coil is fundamental to speaker performance. Analyzing this displacement provides critical insights into both linear and nonlinear transducer behavior. The relationship between voltage input and coil displacement, commonly expressed as the ratio of coil displacement to the input voltage, is a key transfer function. This is typically measured using tools such as TRF and LPM during research and development, as well as TSX during quality control.
Linear parameters, including core Thiele-Small parameters like resonant frequency (fs), mechanical quality factor (Qms), and equivalent air compliance (Vas), are identified using modules such as LSI3 and SPM. Nonlinear parameters are also analyzed to assess characteristics like the force factor (Bl), stiffness (Kms), and peak displacement (Xmax), which are crucial for understanding large-signal behavior.
Understanding voice coil displacement is essential as it allows for accurate prediction of low-frequency performance, the identification of asymmetrical nonlinearity that may cause DC offset, and optimization of the voice coil’s mechanical design to improve durability and sound clarity.
Scanning Geometry
The geometry of a loudspeaker’s diaphragm and cone has a direct impact on vibration patterns and sound radiation. High-resolution scans, conducted with Klippel’s SCN system, capture detailed surface data in cylindrical coordinates, covering diaphragms, cones, and radiators.
This data can then be exported in formats like DXF and STL for use in finite element and boundary element simulations. Regular scanning of prototypes ensures the accuracy of tooling and materials, allowing designers to refine their creations and predict performance across various acoustical environments.
Precise geometry analysis reduces variances in production and aligns mechanical and acoustical characteristics more effectively.
Vibration Analysis
The mechanical vibration behavior of speakers influences everything from tonal quality to structural integrity. In-depth vibration analyses are performed to detect and resolve potential issues early in the design process. Modal analysis identifies natural frequencies, damping factors, and mode shapes, while targeting rocking modes that could lead to voice coil rubbing.
The accumulated acceleration level (AAL) summarizes total vibration and correlates it with SPL at low frequencies. Using modules such as SCN, RMA, and HMA, distributed mechanical parameters are measured, and vibration patterns are animated. These tools also reveal radial and circumferential modes that affect sound quality.
To assess material damping, properties are evaluated, and recommendations for coatings or material changes are made to mitigate excessive vibration. Such analysis eliminates buzzing and rattling, ensuring harmonious diaphragm operation and enhancing tonal accuracy.
Scanning Mechanical Vibration
Klippel’s advanced scanning systems visualize how each point on a radiator’s surface vibrates in response to electrical input. Magnitude and phase plots track vibration behavior across the diaphragm or cone, while 3D animated patterns illustrate how geometry and materials interact under stress.
This data is applied to diagnose rocking modes and asymmetric vibrations and improve performance by making precise structural adjustments to minimize unwanted behavior.
Integrating Insights into Design
The insights gained from voice coil displacement analysis, geometry scanning, and vibration analysis provide a comprehensive understanding of speaker performance.
These findings are used to refine diaphragm shapes and materials for balanced vibrations, ensure consistency through rigorous testing of every speaker in production, and push the boundaries of speaker design to achieve new levels of clarity, reliability, and performance.
