Microphones market report share is projected to reach USD 3.4 billion by 2027 from USD 2.48 billion by 2023, growing at a CAGR of 8.2% during the forecast period.


Wearable devices have gained popularity in recent years, and their market is growing at a high rate. Many wearable devices are integrated with microphones for voice recording and voice command features for such devices. Nowadays, smart glasses integrated with audio, microphones, and a mini display are available in the market. In this year’s CES 2022, the Vuzix Shield Smart Glasses were launched. These smart glasses have immersive noise-canceling microphones, perfect for working in loud environments.

In April 2021, Knowles Corporation announced the availability of two new SiSonic MEMS microphones for automotive applications: SPH1878 and SPH9855. The new best-in-class analog and digital microphones by Knowles are engineered to a higher standard of quality and supply assurance to support the increasing demands of the automotive market for hands-free calling, advanced voice assistance, and in-cabin noise cancellation for passenger comfort.


The resurgence of COVID-19 in China in 2022 has also caused certain disruptions to companies operating in the microphone market and offering microphones to different industries. The risk of a prolonged COVID-19 pandemic might lead to a significant disruption of production and shipment in the smartphone supply chain. In addition to COVID-19, geopolitical events between different nations, such as the Russia–Ukraine war, may have an unpredictable impact on the global markets, such as disruption to the global supply of commodities, including base metals and driving up the commodities’ prices.


The microphone market for medical applications is expected to grow at the highest CAGR during the forecast period. There is growing adoption of MEMS microphones in wireless sound monitoring applications, including breathing sounds in apnea patients, chest sounds after cardiac surgery, as well as for feedback sensing in compression vests used for respiratory ventilation. Also, microphones are used to monitor chest sounds in neonatal care units where the miniature sensors will minimize discomfort for newborns. The latest trend in the market is to tap the power of smartphones for medical and health-related operations. AliveCor’s heart monitor KardiaMobile for smartphones and tablets is an excellent example in this field. The device collects ECG data with the help of electrodes from the skin and converts it into ultrasonic FM sound signals. These signals are then sent to the microphones embedded in the smartphone.
