According to the "China Smart Microphone Market Forecast and Investment Strategy Report
(2019 Edition)" published by LM Information Consulting, MEMS microphones are generally
packaged by MEMS die (Die) and special application ICs, and audio ICs cover audio
amplifiers (Amplifier), audio codec (Codec) and other chips.
In terms of applications, the smart phone-based mobile phone market is the largest
application of MEMS microphones, followed by NB, tablet computers, and personal digital
assistants (PDAs), digital video cameras and other consumer electronic products. Widely
equipped with MEMS microphones.
Knowles Electronics, GoerTek, and AAC Technologies are the top three MEMS microphones
in the world. These three companies are mainly manufactured by Sony or Infineon.
STMicroelectronics, Bosch, TDK, Omron and other integrated component manufacturers
(IDM) are also MEMS microphone suppliers, and there are many related audio industry
supply chain operators.
In 2016, the MEMS microphone market was $993 million, close to the $1 billion mark, and
the $700 million electret condenser microphone (ECM) market, the entire microphone market
is about $1.8 billion.
With the support of smart voice assistants and in-vehicle applications, MEMS microphone
shipments will maintain a high-speed growth trend in the next five years, with a compound
annual growth rate of 11.3%. By 2022, annual shipments are expected to exceed 8 billion.
ECM microphone shipments are slowly shrinking, with shipments of only about 3 billion by
2022.
