Revolutionary low-power radio architecture enables new product category
Kleer announced the availability of the first reference design for small form factor wireless earphones that achieve at least 10 hours playtime of lossless CD-quality digital stereo audio over a robust 2.4GHz radio link. The reference design demonstrates the industry’s first un-tethered earphones, meaning there is no wire necessary between the right earphone and the left earphone. The earphones will work with any Kleer-based audio source, including portable audio/media players, home audio/theater systems, and automotive systems. The reference design includes an optional adaptor for the latest generation iPod. Kleer’s wireless earphone reference design is based on the Company’s KLR3012 RF audio module, the first product in the Company’s recently announced Kleer Audio LP line of RF wireless modules.
“We’re hearing from consumer electronics manufacturers that wireless earphones is the most requested feature in the portable audio market today,” said Ron Glibbery, VP of Marketing for Kleer. “Due to the high power consumption of existing wireless technologies such as Bluetooth, cumbersome over-the-ear style headphones are required to accommodate a large battery. Kleer’s wireless earphone design uses only one-tenth of the power of a comparable Bluetooth design, so our battery size requirements are much smaller.
Wireless earphones provide a variety of benefits over traditional wired earphones. Wires can easily get entangled in hair and clothing, and often get yanked out during physical activity. Wireless earphones based on Kleer technology not only eliminate these problems but also provide additional capabilities such as Kleer’s Listen InTM mode, whereby multiple users can simultaneously listen to one MP3 player or DVD player.
The Kleer reference design for wireless earphones will provide manufacturers with the baseline set of technical information they need to bring these much anticipated wireless earphones to market, including the BOM, schematics and Gerber files. Evaluation kits and the earphone reference design can be ordered by contacting Kleer.
