SAN JOSE, Calif. — Etched into the base of Google’s new wireless home media player that was introduced on Wednesday is its most intriguing feature. On the underside of the Nexus Q is a simple inscription: “Designed and Manufactured in the U.S.A.”

The Google executives and engineers who decided to build the player here are engaged in an experiment in American manufacturing. “We’ve been absent for so long, we decided, ‘Why don’t we try it and see what happens?’ ” said Andy Rubin, the Google executive who leads the company’s Android mobile business.

Google is not saying a lot about its domestic manufacturing, declining even to disclose publicly where the factory is in Silicon Valley. It also is not saying much about the source of many of its parts in the United States. And Mr. Rubin said the company was not engaged in a crusade.

Still, the project will be closely watched by other electronics companies. It has become accepted wisdom that consumer electronics products can no longer be made in the United States. During the last decade, abundant low-cost Chinese labor and looser environmental regulations have virtually erased what was once a vibrant American industry.
