Power amplifying device of landline

座机电话功率放大装置

Abstract

座机电话功率放大装置,属于电子技术应用技术领域。将座机电话机内连接座机电话机受话器喇叭的导线与座机电话机受话器喇叭断开,把座机电话机内接座机电话机受话器喇叭的导线直接与功率放大器的信号输入端连接。这种连接是将座机电话机内接座机电话机受话器喇叭的导线直接固定连接在功率放大器的信号输入端上,或者将座机电话机内接座机电话机受话器喇叭的导线与一个连接插头固定连接,通过该连接插头与功率放大器的信号输入端的插座连接。在本实用新型中,座机电话机与功率放大器都是已有产品,两种产品的连接安装都十分方便。这种座机电话功率放大装置的声音可以调节,能够有效地解决在一些环境噪声大、人员多的场合接听电话难的问题。
The utility model discloses a power amplifying deice of a landline, which belongs to the technical field of the application of electronic technology. A lead wire connected with a landline receiver horn in the landline is separated from the landline receiver horn, and is directly connected with the signal input end of the power amplifying device, therefore the lead wire connected with the landline receiver horn in the landline is directly fixed and connected with the signal input end of the power amplifying device, or the lead wire connected with the landline receiver horn in the landline is fixedly connected with a coupler plug, through which the lead wire is connected with a socket at the signal input end of the power amplifying device. In the utility model, the landline and the power amplifying device adopt the prior products, the connection and the installation of which are very convenient. The power amplifying device of the landline can adjust the sound volume, thereby effectively solving the problem that people are difficult to answer a telephone in occasions where the noise is large and the staff number is big.
