Patent Review: Improved Speaker Structure by Jazz Hipster

This article reviews a patent application submitted in 2010 by to two inventors, on behalf of Jazz Hipster Corp. (Taiwan), regarding an improved structure of a speaker using the surround to reduce the resistance of the diaphragm excursion, which helps to generate a more linear diaphragm movement, with less resistance, and reduced distortion. As James Croft noted, the approach had been used in the past, but its use decreased due to the high-performance achieved with well-designed roll-surrounds, at a lower cost. No surprisingly this patent was subsequently abandoned.

WiSA LLC, the Wireless Speaker and Audio Association comprised of leading consumer electronics brands founded by Summit Wireless Technologies, today announced the addition of five new members. The association was reinforced with TCL Technology, Atlantic Technologies, Zylux Acoustic, Jazz Hipster, and AKSys. These new members will help develop and manufacture additional high-performance products as adoption of WiSA Ready platforms continues momentum.

Much to read in Voice Coil July 2016, starting with an article by Mike Klasco about protection treatments for speakers and mobile electronics, followed by a discussion about “Boundary Effects on Sources at Low Frequencies” by Christopher J. Struck. James Croft reviews a patent of an improved speaker structure and Vance Dickason looks at one ribbon tweeter from Fountek, a new 1” dome tweeter from Tang Band Speaker and a closed-back midrange driver from B&C Speakers, and then reviews Revolution Acoustics’ SSP6 actuator, which is able to transform any panel structure into an audio speaker.
