Yamaha’s Experimental Speakers: A New Direction in Sound Design

Yamaha’s Design Laboratory is pushing the boundaries of speaker technology, moving beyond traditional designs to explore new structural approaches focused on enhancing sound quality and aesthetic appeal. The core principle driving this innovation is minimizing unwanted sound reflections and directing audio upward, resulting in a more immersive and engaging listening experience. This exploration has led to a collection of four distinct prototypes, each embodying a unique concept in speaker design.

Rethinking Speaker Form and Function

Yamaha’s Design Laboratory in Japan is envisioning prototypes that challenge conventional speaker forms. The project aims to achieve a distinctive visual presence alongside a novel auditory experience, differing significantly from traditional speaker designs. This is accomplished through unconventional arrangements of tweeters and woofers, and shapes inspired by nature and musical instruments.

The Four Prototype Concepts

Sail Concept: Interactive Sound Adjustment

The Sail Concept reimagines sound adjustment as a tactile, interactive experience. A sail-like diaphragm, constructed from ROHACELL – a closed-cell rigid plastic foam known for its strength, heat resistance, and thermoformability – is suspended by strings and moved via a dedicated control mechanism. This allows users to physically manipulate and fine-tune the sound. ROHACELL, originally developed by Röhm (now Evonik Industries) for aerospace components, is ideally suited for speaker diaphragms due to its lightweight yet rigid properties. [Designboom]

Butterfly Concept: Liberating Sound from Convention

The Butterfly Concept embodies a departure from traditional speaker forms and fixed listening positions. Its butterfly-like structure minimizes sound reflections by placing speaker units back-to-back, facing a reflector, with only the upper section open. Adjusting the volume balance between the inner and outer chambers alters the spatial spread and character of the sound.

Horn Concept: Ambiguous Sound Origins

Inspired by wind instruments, the Horn Concept features a horn-shaped structure with an open opposite side. This design creates the surprising sensation that the origin of sound is ambiguous. Unlike typical horn-shaped tweeters where the driver is at the rear, this design positions the driver midway along the horn, radiating sound towards the rear and adding an ambient quality.

Cristal Concept: Minimalist Geometry and Sound Reflection

The Cristal Concept utilizes minimal geometric forms to create an emotive figure reminiscent of a “bird on a rock.” A slit-horn structure minimizes sound reflections from the table surface, with only the upper section of the opposing speaker units left open. The diaphragm is made of ROHACELL with a metal sputter finish and is directly bonded to the enclosure, forming a sealed structure.

Yamaha Design: A Legacy of Innovation

Yamaha’s commitment to design extends beyond individual products. Yamaha Design showcases the company’s design philosophy, product evolution, and the insights of its designers. Recent additions to the “Synapses” section include details on the Trova™ and ASTFL. Yamaha has also received recognition for its designs, including awards for the FGDP-50/FGDP-30 and TORCH T01.
