Akustica MEMS Microphones
Our MEMS microphones leverage the combination
of Akustica's microphone expertise and CMOS MEMS technology
with Bosch's 25 years of MEMS intellectual property, process
development, and manufacturing experience. This collective
knowledge base has allowed Akustica to develop a full
portfolio of MEMS microphones that meet the increasing
performance requirements of the consumer electronics
market. Akustica is the industry's only MEMS microphone
supplier to design and manufacture its ASIC and MEMS
in-house, allowing Akustica to quickly introduce innovative
new products to the market and provide a portfolio
of microphones that can be used in almost any smartphone,
laptop, or tablet application including those that require:
- Uniform matching
- Analog or digital-output
- Top- or bottom-port microphones
- HD voice quality frequency response
- Industry standard or smaller sized footprints
