Film enhances acoustic performance in mobile phone speaker diaphragms

21st February 2013


Victrex Polymer Solutions, a division of Victrex plc., announced that APTIV film has been selected by Zhejiang New Jialian, a manufacturer of miniature acoustic components, for its new mobile phone speaker diaphragm.

The company is headquartered in Jiashan, in the Eastern coastal province of Zhejiang in China and researches, develops, manufactures and distributes communication electronic acoustic devices, such as high-performance communications speakers, receivers, buzzers and Bluetooth headsets for global markets. Zhejiang New Jialian selected APTIV film to meet the ever increasing demands of the mobile phone speaker diaphragm application and to overcome various challenges in product design.

The deployment of APTIV high performance film improves the acoustic performance, durability and life span of the new speakers. With an established track record of success in mobile phone speaker diaphragms Victrex’s APTIV film provides a significant improvement in processability, acoustic performance - especially in low end response, durability, high temperature performance at temperatures exceeding 220°C (428°F), chemical resistance, tear resistance, and fatigue resistance versus other high performance films on the market.

“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 APTIV 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. “Our partnership with Victrex will enhance our competitiveness in the market and enable our focused commitment to creating a robust user experience.”

“APTIV films offer a broad range of thicknesses from 6 to 750 microns along with outstanding film thickness tolerances to provide consistent acoustic properties, and through standard processing techniques, it can be formed into complex shapes and unique designs. This critical advantage makes APTIV film a good fit for parts and components in miniature speakers,” said Edmond Chu, APTIV Films Manager, Victrex Asia Pacific.

Due to its versatility, APTIV film can satisfy a range of speaker diaphragm designs including; single layer, multilayer, specialty acoustics coated diaphragms, filled acoustic grades, and diaphragms with ceramic stiffeners. The inherent acoustic properties combined with high temperature, mechanical, fatigue and processing attributes of APTIV films, produced from VICTREX PEEK polymer, are well suited for use in acoustic film applications and present numerous opportunities for OEMs, designers and processors in the manufacture of leading edge, high performance speaker systems and acoustics related components.
