5.结构发射机的结构型式大体上可分为手持式与分离式两种。手持式是传声器极头与发射机电路合二而一。分离式则是传声器极头与发射机电路分开。手持式发射功率大约在30～50mW之间。分离式带有可供选择的500mW功率放大器,其发射机和功率放大器都装在腰部位置上,发射天线固定在头戴受话器的头带上。在实际使用中,多采用分离式结构,如佩带式、披肩式、别挂式等各种型式。接收机的结构型式基本上是趋向于功能、组件化。结构简单、可靠,使用、维修方便。采用单元化,插入式结构。机壳全部标准化,既适用于单信道工作,又适用于多信道工作,
5. Structural transmitter structure can be divided into two types of handheld and separate. Hand-held microphone is a combination of transmitter and transmitter pole. Separately, the microphone tip is separate from the transmitter circuit. Hand-held transmit power of about 30 ~ 50mW. Separate with an optional 500mW power amplifier, the transmitter and power amplifier are mounted on the waist position, the transmitting antenna is fixed on the headset headband. In actual use, more use of separate structures, such as wearing, shawl, do not hang and other types. The structure of the receiver basically tends to function, componentization. Structure is simple, reliable, easy to use and maintain. The use of unitized, plug-in structure. Fully standardized chassis, both for single-channel work, but also for multi-channel work,
