parametric speaker – Backerjack

“A” speaker can send audio only to “U”

When listening to music at work or watching TV at home while other people are sleeping, it’s convenient to have a speaker that only delivers sound in the user’s direction.

“A” speaker does exactly that. It’s parametric speaker, that is, a speaker that sends audio only to those people who want to hear it by creating a narrow beam of sound, in much the same way that a laser creates a beam of light to focus on a precise area. Instead of producing ordinary sound waves with a single, moving electromagnetic coil and cone, “A” generates ultrasonic waves (high-frequency sound waves) that are then turned into audible sound waves. Users can connect “A” to mobile devices, stereos, TVs or any other audio sources via a 3.5mm mini-jack.

Wakē shines a little light — and audio — to rouse without disturbing mattress mates

The smartphone has encroached upon the classic clock radio as the tool of choice for greeting the day, but both offer an escape from slumber via sounds delivered at an elevated decibel. That can mean a rude awakening for the person who shares a bed with the early riser.

Wakē swivels to project a light and parametric speaker (one that can focus a beam of sound) that work together to gently wake owners and their bedfellows individually. The product mounts above the bed on a wall. From there, a companion smartphone app communicates when and how the sleeping should be awoken with a combination of light and sound. Wakē can hone its spotlight and audio beam on bed occupants even if they are spooning. However, pre-empting concern about (unwanted) cameras in the bedroom, the product relies on heat seeking to identify which person should receive its stimuli. Developer Lucera Labs seeks $100,000 by May 30th. Backers can pick up a unit for $250 (or $125 per bed occupant).

Wake has more applications on the drawing board; a reading light is a natural next step. The product represents the most radical rethinking of the alarm clock in a long time. It’s unusual position in the bedroom and need to be charged every few months, though, diminish ts useful impact for couples. somewhat Still, it represents the most clever use of parametric speaker capabilities to date.
