Patent Review: A Speaker Device Offering Extended Bass Performance

This review discusses an intriguing speaker design patented by Walter Ka Wai Chu, from Taiwan. The design allows the speaker device to potentially improve the bass performance in the entire low-frequency band instead of being limited to only a few low-frequency points, the inventor claims. While James Croft confesses to being somewhat skeptical of whether, in its current disclosed form, the device will provide a useful advantage, he found the design sufficiently interesting to be analyzed in more detail.

A new analysis for 2014 titled “The Global and China Micro Electronic-Acoustics Component Industry Report, 2013-2014” was published in October 2014 by Research in China and shows that the earphone and headphone categories have been the main growth areas since the second half of 2013. The 95 pages report provides the most recent data and information on the micro electronic-acoustics industry, detailing profiles of 21 micro electronic-acoustics manufacturers.
