Typ512

To enhance reliability and deliver maximum performance, we have adopted the proprietary housing architecture “MIAA: MADOO In-ear Acoustic Architecture” from the Typ711. All products are developed based on this architecture.

We refer to the component housing the driver as the acoustic box. This acoustic box is manufactured using a 3D printing process and incorporates a complex acoustic circuit known as schematic design.

Many multi-driver earphones on the market employ sound tubes made of vinyl tubing. However, vinyl tubing presents several challenges: the material itself is soft, significant sound loss occurs due to crushing from bending, and even with optimal design, manufacturing instability leads to inconsistent characteristics. In other words, these earphones exhibit individual variations, leaving users at the mercy of fate, much like with musical instruments. To address these issues, we developed the housing architecture “MIAA” as a solution.

Each driver is fixed in a robust and precise position, with sound guided through acoustically engineered sound tubes. The acoustically optimized sound tubes, designed using schematic design, feature optimized hole diameters, lengths, filtering functions, and bore functions. This enables the delivery of exceptional sound. For the ‘Typ512’, we implemented new, acoustically unique tube designs, such as non-uniform diameter tubes and composite spline tubes. This allowed for complex acoustic designs unattainable with molds or vinyl tubes. Additionally, improvements were made to the 3D-printed components, with the new model adopting precision resin. To maximize the potential of this resin, the manufacturing process was revised, specifically the pre-cure and post-cure hardening steps. This enabled the production of extremely precise components managed at the 5μm level. Consequently, quality is strictly controlled, minimizing manufacturing variations. Users can enjoy the sound quality exactly as intended by the design.
