Description

Technical Field

[0001] The utility model relates to the field of microphones, in particular to a microphone device with a dual-cavity structure. Background Art

[0002] Wireless microphone-integrated speakers have become a popular new type of smart microphone for home use in recent years. They cleverly combine a microphone and a speaker, with built-in speaker functionality for external playback. Currently, there are two main types of integrated microphone-integrated speakers: condenser and dynamic. Condenser microphones focus on sound pickup, while dynamic microphones offer advantages in noise reduction and loudness.
