LONGER LIFE AND MORE FEATURES FOR EARBUDS

The Nanusens solution

Free up space for battery

Multiple sensors on one chip

Roadmaps of solutions for earbuds

A typical MEMS sensor package is 4mm3 but ours is only 0.5 mm3 so we free up 3.5 mm3 for every sensor replaced with one of ours. So, three MEMS sensors replaced frees up 10.5 mm3 for example and needs less PCB real estate. This can be used for bigger batteries or a supercapacitor to give Longer audio on the go™.

These are of two types. First, sensors such as bone conduction sensors to detect the user’s voice so that noise cancelling algorithms provide better outgoing voice quality. Second, enhanced situational awareness so that the earbud can detect if it is in the ear, in a pocket or on a surface in order that it can automatically turn itself on or off to conserve battery life. Again for Longer audio on the go.

Our nanosensors can be easily added as they take up very little space giving them the freedom to design in as many sensors as they want.

Roadmaps of solutions for earbuds

The first product from Nanusens will be a 2D motion detector for earbuds in 2024, which can be used to implement tap and double tap for control, wake-on-movement and sleep-on-rest functions, and, soon after, a 3D accelerometer. A bone conduction sensor for noise cancellation is next to be integrated into the single chip solution. Chips will be available in a small package such as WLCSP or as bare die that can be attached directly to the PCB. Nanusens can deliver solutions for earbuds that no one else can. +

Headphone sockets are being designed out

The key driver for earbud market growth is that phone manufacturers are designing out bulky headphone sockets to free up space inside phones for larger batteries and more features, and using Bluetooth connectivity to earbuds. With 1.5 billion smartphones shipped each year, the market potential for Nanusens technology into the earbuds that these will need is tremendous.
