Super Ultra-small Type of MEMS Microphone Unit Has Been Developed

For the market of compact microphones including smart phones, Hosiden has developed and started to expand, as a new variation of analog MEMS microphones, Super Ultra-small Type (3.35 x 2.5 x 1.0), which aims at further downsizing and low-profiling. (We have a lineup of top sound hole type and reverse sound hole type.)
Maintaining acoustic characteristics and reliability equivalent to Ultra Small Type (3.76 x 2.95 x 1.1), which was the smallest size in the past, Super Ultra-small type has accomplished further downsizing of the package and will meet the downsizing and low-profiling needs of our users (equipments).
A wide variety of demands are expected for this product as a microphone unit used in smart phones, portable game machines, digital cameras, tablet PCs; etc.

Typical Features
  • We tried to downsize and low-profile (shrink) the microphone package. (Compared with the conventional Ultra Small Type, it has been downsized to about 69 % in volume; that is, from 12.2mm³ to 8.4 mm³.)
Typical Application
  • Mobile phones, smart phones, PCs, game machines, digital cameras/ video cameras, automotive equipments; etc.
