调频无线话筒的设计与制作
随着数字技术的广泛应用,从电子管到晶体管、从动圈到电容、从微型话筒到金话筒等.话筒在广播、电影、戏剧和舞台制作以及公司、娱乐和教育场所都是重要的组成部分.
调频无线话筒的原理是将声波信号通过麦克风转化为音频电型号,通过改变结电容来改变高频振荡器的输出频率,产生调频波,通过高频放大与选项,最终由天线发射.因其具有体积小、重量轻、电路简单、成本低廉、无电线传送等特点,因而得到了灵活广泛的应用.
无线话筒按照调制方式可分为调频式和调幅式,调频式具有通频宽带、动态范围大、传输距离远和抗干扰能力强,所以应用较多.
With the extensive application of digital technology, from tubes to transistors, capacitors driven into rings, gold from the microphone to the microphone and so on. Microphone in the broadcast, film, theater and stage production, and corporate, entertainment and educational establishments are important components.FM wireless microphone is the principle of acoustic signals through a microphone into the audio type, by changing the junction capacitance to change the high-frequency oscillator output frequency, frequency waves generated by high-frequency amplification and options, and ultimately by the antenna. Because of its small size, light weight, simple circuit, low cost, no wire transfer characteristics, which have a flexible range of applications.Wireless microphones can be divided according to modulation and amplitude modulation Frequency Modulation, Frequency Modulation with a passband bandwidth, dynamic range, transmission distance and the anti-interference ability, it used more often.
