Electro-acoustic components refer to devices that convert electricity and sound. It uses electromagnetic induction, electrostatic induction or piezoelectric effects to complete electro-acoustic conversion, including speakers, headphones, microphones, cartridges, etc.

The application fields of electroacoustic components are very extensive, and the downstream applications involve many fields such as consumer electronics, medical care, automobiles, smart homes, and artificial intelligence.

In recent years, thanks to the development of consumer electronics, smart speakers and other markets, the market size of electroacoustic components has shown significant growth. It is estimated that my country's electroacoustic component market will maintain a compound annual growth rate of 15.6%, reaching 46 billion yuan.

Electroacoustic components mainly complete the process of electronic equipment from sound collection to playback through three main parts: microphone, audio IC and speaker, so as to realize sound reproduction.

Microphones, audio ICs and speakers are the three major market segments of electro-acoustic components, among which microphones are key devices for collecting sound; speakers are electro-acoustic devices that convert audio current into sound; audio ICs are used for reading and processing audio analog signals. Demodulation, conversion between analog and digital signals, adjustment of volume and sound quality, etc.

Among electro-acoustic components, the technical threshold of audio IC is the highest. According to the report of Hengzhou Bozhi: In recent years, with the advancement of domestic technology, my country's electroacoustic component companies have gradually moved from the low-end field to the high-end field, and the high-end and diversified development trend of the electroacoustic component industry has emerged. In the future, driven by the upgrading of market demand, increasing the added value of products, strengthening brand building, upgrading new materials, and improving product performance are still the key directions for the future layout of electro-acoustic component companies.
