The utility model provides a secondary wiring free loudspeaker, the secondary wiring free loudspeaker includes a case and a main board arranged in the case, the rear side of the case is provided with a wiring free terminal, the wiring free terminal includes a wiring free terminal body, the wiring free terminal body is provided with four female sockets, each female socket is provided with a contact pin electrically connected with the main board, and the main board is equipped with a contact pin Two of the four female sockets are the female sockets of the power line for connecting with the power line, and the other two are the female sockets of the horn line for connecting with the horn line. The rear side of the case is provided with marks on the left and right sides of the terminal free from wrong connection with the male plug, so that when connecting the power line and the horn line, only the male plug of the horn line and the power line needs to be connected with the female plug, It is no longer necessary to distinguish the power line and the horn line. For those who have electronic technology or not, they can be correctly wired, so as to effectively solve the problem that the power line and the horn line are easy to be connected and cause short circuit and burning.

一种免二次接线扩音机
本技术涉及扩音机
,具体涉及一种面二次接线扩音机。
技术介绍
功率放大器简称功放,俗称扩音机,是音响设备系统中最基本的设备,它的任务是把来自信号源的微弱电信号进行放大以驱动扬声器发出声音。扩音机包括机箱和设置在机箱内主板,机箱的前侧面上设有音量调节旋钮、播放/暂停按钮、歌曲选择按钮、模式切换按钮、放音/录音选择按钮、警报/重复选择按钮、USB接口、TF插口、话筒插口和录音口,机箱的后侧面上引出有与主板连接电源线和喇叭线,每次在使用时,首先需要接上电源箱和喇叭线(二次接线),但由于电源线和喇叭线只是机箱后侧面上引出的四根线,并与特殊标记。因此,在接电源线和喇叭线,需要首先区分开电源线和喇叭线,对于无电子技术的人来说,很容易将电源线和喇叭线接反而造成短路、烧机的问题。
技术实现思路
本技术的目的在于提供一种免二次接线扩音机,旨在解决现有技术中扩音机容易将电源线和喇叭线接反而造成短路、烧机的问题。为实现上述目的,本技术一种免二次接线扩音机如下技术方案:所述免二次接线扩音机,包括机箱和设置在机箱内的主板,所述机箱的后侧面上设有免接线端子,所述免接线端子包括免接线端子本体,所述免接线端子本体上设有四个母插口,所述各母插口中均设有与主板电连接的触针,其中四个母插口中的两个为用于与电源线插接的电源线母插口,另两个为用于与喇叭线插接的喇叭线母插口,所述机箱的后侧面于免接线端子的左右两侧设有避免与公插口插错的标记。所述主板上设有用于无线通讯的蓝牙。所述机箱的前侧面上设 ...
