FM radio receiver design and production
隨著數字技術的廣泛應用，從電子管到晶體管、從動圈到電容、從微型話筒到金話筒等。話筒在廣播、電影、戲劇和舞臺制作以及公司、娛樂和教育場所都是重要的組成部分。
With the wide application of digital technology, from the valve to transistor, driven circle to capacitor, from the tiny microphones to gold microphone, etc. Microphone in broadcasting, movie, drama and stage production and company, entertainment and education places are important component.
調頻無線話筒的原理是將聲波信號通過麥克風轉化為音頻電型號，通過改變結電容來改變高頻振蕩器的輸出頻率，產生調頻波，通過高頻放大與選項，最終由天線發射。因其具有體積小、重量輕、電路簡單、成本低廉、無電線傳送等特點，因而得到了靈活廣泛的應用。
FM wireless microphones is principle will acoustic signals through a microphone into audio electricity model, by changing the junction to change the high frequency oscillators output frequency, produce FM wave, through high frequency amplifier applications and options, and finally the antenna launch. Because of its small volume, light weight, low cost, simple circuit, no wire transfer characteristics, obtaining a flexible widely.
無線話筒按照調制方式可分為調頻式和調幅式，調頻式具有通頻寬帶、動態範圍大、傳輸距離遠和抗幹擾能力強，所以應用較多。
Wireless microphones according to modulation mode can be divided into FM type and amplitude type, FM type with general frequency broadband, dynamic range, the transmission distance and strong anti-jamming capability, so used more often.
