Aptiv Film Enhances Mobile Phone Speaker Diaphragm

Zhejiang New Jialian, a manufacturer of miniature acoustic components, has selected Victrex Polymer Solutions' Aptiv film for its new mobile phone speaker diaphragm. The company, headquartered in Jiashan, China, researches, develops, manufactures and distributes communication electronic acoustic devices, such as communications speakers, receivers, buzzers and Bluetooth headsets. Zhejiang New Jialian selected Aptiv film to meet the increasing demands of the mobile phone speaker diaphragm application and to overcome various challenges in product design.

The deployment of Aptiv film is intended to improve the acoustic performance, durability and lifespan of the speakers. Compared with similar products, Victrex claims that its Aptiv film provides an improvement in processability, acoustic performance (especially in low-end response), durability, high-temperature performance at temperatures exceeding 220C (428F), chemical resistance, tear resistance and fatigue resistance.

'Using Aptiv film allows us to produce new mobile phone speakers with compact size and high power-output performance,' said Jin Yidong, vice general manager of Zhejiang New Jialian. Edmond Chu, Aptiv films manager at Victrex Asia Pacific, said: 'Aptiv films offer a broad range of thicknesses from six microns 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,' he added.

Aptiv film can satisfy a range of speaker diaphragm designs, including single-layer designs, multilayer designs, speciality acoustics-coated diaphragms, filled acoustic grades and diaphragms with ceramic stiffeners. The acoustic properties and the high-temperature, mechanical, fatigue and processing attributes of Aptiv films, produced from Victrex Peek polymer, are suitable for use in acoustic film applications for original equipment manufacturers, designers and processors in the manufacture of speaker systems and acoustics-related components.

Han® HC 250 high current contact

A Powerful Solution HARTING has developed the new Han® HC 250high current connector as a powerful interface that impresses by requiring little space, transmitting high current intensities and allowing flexible configuration of the number of poles. The HC 250 one-pole crimp module can be connected in various frame geometries to produce the required number of poles in a compact space – and in the existing Han® HPR housing. Technical details: - Rated current 250 A at a rated voltage of 2000 V - Termination cross-sections are: 35 mm2, 50 mm2 and 70 mm2 - Maximum four-pole interfaces in a size 24 B HPR housing, making it particularly suitable for motor connections - High quality plastic with good smoke and inflammability levels - Removal tool for simple installation and removal of the contacts and inserts - Confusion of a number of interfaces is reliably prevented by multiple coding options for the individual inserts The requirements in the railway industry are changing, as

EGCS-D0 Accelerometer Now Available in 10,000g Range

Measurement Specialties, Inc. (NASDAQ: MEAS) has recently redesigned the EGCS-D0 accelerometer to enable it to accurately and reliably measure up to ±10,000g. This rugged device is critically damped, which is the ideal mechanism to protect the accelerometer against ±20,000g impacts and prevent sensor ringing. The EGCS-D0 accelerometer is now available in ranges from ±5g to ±10,000g which makes it ideal for both critical low-g measurements and high-g impacts. These units feature a Wheatstone Bridge mV output with a standard compensated temperature range of 20ºC to 80ºC (other options available). The EGCS-D0 was specifically designed for impact and shock testing in auto safety, aerospace, military and civil engineering applications. Designed to be bolt-mounted, this device operates from 2-15Vdc excitation with electrical output ratiometric to voltage input. Optional triaxial mounting blocks (MTG-F4), signal conditioners (Model 101) and auto-zero inline amplifiers (Model 140) are avai

Ilix Cermet Reamers Are Ideal For Dry Machining Engineers Cutting Tools, the UK agent for Ilix, has introduced Ilix solid-carbide and cermet reamers for the machining of hard metals. The machine reamers 6372C and 6323 allow the production of high-precision holes with good surface finish. Compared with HSS, the solid-carbide qualities enable the increase of cutting parameters and tool life. The quality of the reamers is said to guarantee high performance, even for hard metals with a resistance more than 1200N/mm2. The Ilix carbide 6372C range of hundredth reamers is from 0.98mm through to 12.05mm in increments of 0.01mm. The reamers are manufactured to a tolerance of +0.000 - +0.004mm. The cermet reamers 6323 have new cutting geometry developed by Ilix. These reamers are said to be ideal for steel machining, having high chemical stability during the cutting process. They offer good wear resistance due to the high hardness and have low material adhesion. The Ilix cermet reamer is said to
