[0002] A microphone, also known as a micro-phone or a microphone, is formally called a microphone in Chinese. It is a transducer that converts sound into electrical signals. The commonly used transmission of wireless microphones is divided into three frequency bands: FM, VHF and UHF.
[0003] The UHF band, commonly referred to as the U band, operates in the 500-980MHz frequency range. This high frequency is virtually immune to interference from other external frequencies. U-band devices primarily utilize surface-mount components, resulting in very stable performance. The analog audio circuitry in the U band utilizes the latest low-noise, high-fidelity circuitry, resulting in excellent sound quality. However, existing U-band microphones, when connected to smart devices, are prone to transmission delays in vocals and accompaniment, impacting user experience.
