Trends in portable consumer electronics are driving the need for improved sound quality, clarity and performance in thinner, lighter and smaller formats. To satisfy these demands, design engineers have discovered that UK-based Victrex’s APTIV films offer the necessary combination of reliability and acoustic quality for speakers for mobile devices such as smart phones, ear buds, headphones, laptops, and tablets.

According to a leading manufacturer of miniature acoustic components, Zhejiang New Jialian, the use of APTIV film in their new mobile phone speaker diaphragm has improved the acoustic performance, durability, and lifespan of the product. “Other films are not available in the range of thicknesses offered with APTIV films and do not provide the same level of performance and versatility, especially in this very thin format. Using this film allows us to produce new mobile phone speakers with compact size and high-power output performance,” said Jin Yidong, the Vice General Manager of Zhejiang New Jialian.

With products getting thinner and smaller, recreational use of portable electronics is on the rise, making sound quality a significant contributing factor to an enjoyable consumer experience. APTIV acoustic film technology, based on VICTREX PEEK polymer, can help improve consumer satisfaction by providing the reliability and durability that these users desire. Membranes made from APTIV films increase speaker lifetime by up to 300%, helping manufacturers and consumers avoid the frustrations of membrane distortions and ruptures that can be found when using traditional materials.

For the past six years, APTIV films have delivered reliable acoustic performance in more than 750 million mobile devices. “These specifications continue to grow and prove that APTIV thermoplastic films deliver the best results in continuous high power reliability tests with stable properties over demanding operating conditions including temperatures that exceed 200°C (392°F),” said Tim Herr, Global Films Business Leader for Victrex. “This material is also highly customizable when it comes to designing smaller membranes with optimal stiffness and damping characteristics that will not compromise quality and acoustic performance.”

Thermoplastic APTIV films are extruded to extremely tight thickness tolerances as part of Victrex’s fully integrated supply chain to guarantee material quality, supply, consistency and performance. Available in widths up to 1.45 m and in thicknesses from 6 to 750 microns, these PEEK-based films provide the design flexibility for secondary processing operations such as thermoforming and lamination.
