Manejo de potencia

En el corazón del diseño de los nuevos transductores RCF hay grandes cantidades de tiempo y recursos invertidas en ciencia de materiales, investigación en topología de diseño y pruebas de potencia para desarrollar productos estructuralmente muy resistentes, con características térmicas óptimas y el mejor manejo de potencia. Los ingenieros de RCF Precision han desarrollado un material de poliimida capaz de aguantar temperaturas de hasta 380 °C, que va más allá de los requerimientos térmicos de los sistemas profesionales modernos de sonido. La combinación de este material con adhesivos especiales, nuestra tecnología de bobinas interiores y exteriores, las arañas dobles de silicona, la hiperventilación forzada doble y los conos hechos con un tratamiento de fibra especial hacen que la familia de productos RCF tenga los transductores más resistes y fiables de la industria.

Debido a que las aleaciones de titanio tienen una gran resistencia a la corrosión y a la fatiga, una alta resistencia a la tracción para su densidad, gran resistencia a las fisuras, y pueden aguantar grandes temperaturas, se utilizan en la industria aeronáutica y espacial, en los productos deportivos de alta calidad, en los coches de lujo y, cómo no, en los transductores de RCF. Las estructuras de cúpula de titanio combinan la fuerza de los diafragmas fenólicos y de material compuesto con una respuesta en frecuencia impresionante, similar a la de otros materiales más delicados.

High-Class Neodymium: Best-in-Class Magnets

Neodymium, a rare earth material, enhances efficiency, power handling, and weight reduction. Our designs, with a 20% stronger magnetic field than typical neodymium grades, enable precise voice coil control and higher force levels (BL). Magnet geometry and configuration are optimized for maximum flux density, incorporating thermal management to ensure reliability. Techniques such as computer-aided magnet optimization and FEM analysis refine magnet weight, flux density, and field saturation, significantly reducing driver weight and harmonic distortion.
The T-pole design minimizes flux modulation in the magnetic assembly during typical voice coil movements within the gap. A specially designed copper ring, pressed onto the pole piece, modifies and reduces the magnetic circuit and voice coil inductance, enabling a controlled extension of the acoustic frequency response.

Sistemas dobles hyper-vented

Our cooling designs combine various components to create an ideal ventilation system. The RCF engineering team emphasizes finned cooling channels and optimizes the surface area of the front magnetic plate for efficient heat dissipation. The double silicone sealed spider design functions as an air pump, expelling hot air and drawing in fresh air with each movement of the cone assembly.

Montaje del diafragma

The latest RCF Precision Transducers incorporate several cutting-edge technologies. The diaphragm and suspension are precision-crafted significantly reducing distortion by eliminating resonance points and aiding in suspension breakup mode control. RCF has mastered an oxygen-free process for molding titanium ultrathin films into high-quality, precisely shaped diaphragms. Our current Polyimide-Kapton dome with new bonding technology and reinforced ribs, is ten times more durable than previous models. Additionally, we've redesigned the phase plug to enhance sound clarity and precision and improve coupling with the low-frequency transducer.

Montaje direct drive de la bobina

In the Direct Drive configuration, the top of the former is bent and bonded directly to the edge of the titanium diaphragm. This setup ensures optimal energy transfer between the voice coil and the dome assembly, resulting in a smoother, extended frequency response beyond 10 kHz, reducing break-up modes, and lowering distortion. This assembly delivers not only high power handling but also excellent mechanical and thermal properties, making RCF compression drivers robust and reliable.

Correctores de fase

Through extensive computer-assisted mathematical modeling and testing, we've developed phase plug geometries that ensure balanced acoustic performance by controlling and lowering air distortion and maximizing output. This allows for a lower compression ratio, generating substantially lower distortion artifacts. The result is high output with smooth acoustic frequency response and low harmonic distortion artifacts. Our compression drivers feature 4-slot, 3-slot, and 2-slot radial-optimized geometry phase plug designs.

Circuitos magnéticos

El diseño del circuito magnético de neodimio de RCF Precision proporciona un campo magnético más potente en el entrehierro de la bobina que los montajes convencionales de cerámica, a la vez que disminuye el peso de la unidad. El neodimio, un material del grupo de las tierras raras, también ofrece mayores niveles de fuerza (BL) que aumentan el control de la masa móvil de la cúpula. Esto se traduce en una mayor eficiencia, una mejor respuesta de transitorios y una menor distorsión de agudos. El nuevo diseño del circuito magnético de ferrita de RCF está optimizado para que el campo magnético ofrezca una fuerza máxima en el entrehierro de la bobina, lo que da el impulso necesario para controlar con precisión la masa móvil de la cúpula. Un fino anillo de cobre se prensa con precisión en la pieza polar para modificar y disminuir las propiedades de inductancia del circuito magnético y la bobina, lo que proporciona un aumento controlado de la respuesta de frecuencia acústica. RCF Precision ha incorporado aletas de refrigeración en la parte trasera del diafragma de aluminio para crear una superficie que disipa el calor del circuito magnético del motor. Esto ayuda a disminuir la temperatura del circuito, mejorar la potencia de compresión del motor y aumentar la potencia de salida.
