Voice Coil January 2019 is Here and Ready for Another Year!

Voice Coil January 2019 is now available. This edition focuses on New Materials for Earphones and Headphones and also includes a valuable listing of Earphone and Headphone Manufacturers and a schedule of headphone-centric events for the year. In Acoustic Patents, James Croft looks at a new patent of a multilayer voice coil plate and flat speaker based on the same, while in this month's Test Bench Vance Dickason features a 1" compression driver from Radian Audio Engineering, and a 1" soft dome tweeter from Eminence. This is much more, now available in print and download.

To house small PCBs using USB as the external power and signal interconnect, Hammond Manufacturing has extended its popular 1551 miniature family of IP54 ABS enclosures. This allows the development of USB powered products, leveraging the latest USB 3.1 10Gbits/s standard with generous internal room for PCBs. All versions feature a dedicated cut-out for a standard USB Type A plug in one end and have a recess in the lid for an inlay, label or HMI keypad.
