该耳机防止播放设备被盗的工作过程如下：The working process of the earphone to prevent the playback device from being stolen is as follows:
用户将该耳机插入播放设备后，使用该耳机听音乐时，左声道节点12电压大于或等于预设电压阈值即第二二极管D2的导通电压，第二二极管D2导通，第一二极管D1未导通，播放设备通过耳机接头1、第二二极管D2和电容C形成的回路自动对电容C进行充电，耳机不发出提示音。当耳机意外拔出播放设备时，例如有人正在盗窃播放设备而拔出耳机时，左声道节点12电压等于零，电容C对外放电，第一二极管D1导通，第二二极管D2截止，耳机马上发出刺耳的噪声作为提示音，以实现提醒用户耳机与播放设备已经分离。After the user inserts the earphone into the playback device and uses the earphone to listen to music, the voltage of the left channel node 12 is greater than or equal to the preset voltage threshold, which is the conduction voltage of the second diode D2, and the second diode D2 is turned on. The first diode D1 is not conducting, and the playback device automatically charges the capacitor C through the loop formed by the earphone connector 1, the second diode D2 and the capacitor C, and the earphone does not emit a prompt sound. When the earphone is accidentally pulled out of the playback device, for example, when someone is stealing the playback device and pulls out the earphone, the voltage of the left channel node 12 is equal to zero, the capacitor C is discharged to the outside, the first diode D1 is turned on, and the second diode D2 is turned off , the earphone immediately emits a piercing noise as a prompt tone to remind the user that the earphone has been separated from the playback device.
不难理解，当用户不需要使用播放设备听音乐时，用户可以先取下耳塞，再从播放设备拔下耳机接头1，即可避免耳机发出提示音对用户的影响。It is not difficult to understand that when the user does not need to use the playback device to listen to music, the user can first take off the earplugs, and then unplug the earphone connector 1 from the playback device, so as to avoid the influence of the earphone's prompt sound on the user.
