InventHelp Inventor Develops Sound Amplifier for Mobile Phones (LAX-871)

Share Article

Pittsburgh-based InventHelp, a leading inventor service company, is submitting this client’s idea, Echo Case, in the hopes of a good faith review.

"I could not afford a hands-free device, and I noticed that the sound from a phone’s tiny speaker amplifies when it is cupped," said an inventor from Hesperia, Calif. "I started setting my phone in a cup holder to take advantage of this boost. This led to my current invention idea."

He created a prototype for the ECHO CASE to amplify the sound from the phone’s speaker. The unit eliminates the need to purchase expensive after-market speakers. It offers improved sound quality. The device is adaptable for use with new and existing mobile phones. Additionally, the accessory features a compact, easily portable design for ease in storage and transport.

The original design was submitted to the Los Angeles office of InventHelp. It is currently available for licensing or sale to manufacturers or marketers.
