Campfire Audio uses 3D printing for new Supermoon headphones

0

Campfire Audio, a manufacturer of headphones and in-ear monitors (IEMs), has leveraged 3D printing to better customize its new Supermoon Planar Magnetic IEM model.

The IEM’s patent-pending solid-body design provides optimized acoustic performance as well as a personalized, unique fit for the wearer, made possible by a combination of 3D scanning and 3D printing technologies.

“All of our headphones are designed to create an elevated listening experience for our customers – from touring musicians and sound engineers to music lovers who want to take their listening to the next level,” said Caleb Rosenau, Vice President of Campfire. Sound.

“With Supermoon, we’ve used our custom planar magnetic driver to achieve a new standard of audio clarity for our custom offerings, and we’re happy to invite our customers to take the leap to a new plateau in custom audio themselves. . live.”

The 3D printed IEM Supermoon

IEMs are devices used by musicians, sound engineers, and audiophiles to listen to music or to hear a personal mix of vocals and stage instruments for live performance or mixing in the recording studio. Television presenters also use IEMs to receive voice instructions, information, and last-minute announcements from a producer.

Campfire Audio’s Supermoon IEM is powered by the company’s brand new custom planar magnetic driver, a device that converts electrical signals into sound waves. Planar magnetic speakers do this through a flat diaphragm as opposed to a typical cone-shaped diaphragm found in common loudspeakers to deliver improved sound quality.

The drivers are nested within Campfire Audio’s patent-pending solid-body earphone design, which is customized for each user through the use of 3D printing. The company’s custom fitting process begins with taking ear impressions from a customer, from which the interior acoustic chambers of the IEM are mapped and aligned with the planar speakers for audio performance. optimized.

The IEM is 3D printed as a single component with minimal moving parts to maximize reliability and longevity of the earphone, before being hand finished with a stainless steel faceplate. The use of 3D printing allows the outer body of the IEM to conform perfectly to each unique ear shape in two different fits: “Artist” and “Audiophile”.

The Artist fit provides a shallow seal to improve comfort and is designed for everyday use, from one person’s daily commute to the studio. The Audiophile fit, on the other hand, offers a more traditional sealing depth to provide the sound isolation and security needed for demanding stage performances, and is designed for professional musicians.

Priced at $1,500, the Supermoon IEM is marketed to music industry professionals and committed headphone enthusiasts willing to part with a substantial sum for a superior listening experience.

Acoustic Additive Manufacturing

3D printing is increasingly being used in the R&D and manufacturing of objects with sound-enhancing and waterproofing properties. In the past, the technology has been deployed to improve the acoustics of guitars and to meet sophisticated underwater acoustic sonar applications.

Last year, Fraunhofer UMSICHT and Fraunhofer IBP fabricated 3D-printed mushroom-based soundproofing devices that could form a new line of durable acoustic prototypes that offer superior performance to conventional products. Meanwhile, TU Delft and Materialize have worked together to develop 3D printed sound absorbing acoustic panels for use in concert halls and sports arenas.

More recently, the University of Strathclyde and the University of Glasgow have been awarded just under £500,000 to develop miniaturized 3D printed acoustic systems formed from metamaterials, which could form the “next generation” of technology in building projects. portable consumption.
