Energy Efficiency – Part III/III: What fruit flies and jet engines have to do with microspeakers?
How much energy is necessary to generate a certain sound pressure in the ear canal? The kinetic energy of a slow-flying fruit fly is sufficient for this!
Part II: Efficiency of Electrostatic MEMS Transducers
In an in-ear device, a big part of the energy budget is consumed by sound generation. To further develop hearables, electrostatic microelectromechanical transducers offer the optimal solution for creating sound.
Part I: We need more battery!
For wearables, such as TWS earbuds, daily charging is the norm. The reduction of the size and additional new features of wireless in-ear devices further reduce battery life. It is important to use such components that consume less power.
Hearables: A universe of smart applications in your ear
Hearables are inconspicuous in size, yet they will have a major impact on our lives. What functionalities will these smart earphones bring to enhance our day-to-day interaction?
Can Germany catch-up on growth financing?
In an EU comparison, Germany is below average in venture capital investments. The Zukunfstfonds is a step in the right direction to catch up in growth financing.
How we produce sound with tiny air chambers inside a 10 mm² MEMS chip
Smart hearables require small micro speakers. We reveal the secret how sound can be created with tiny air chambers inside a 10 mm² MEMS chip.
Disruptive Times for In-Ear Devices
To help hearing loss, more and more new ideas, features and applications are emerging. Hearing aids are increasingly taking the form of hearables, equipped with AI functions.
