[0008] Preferably, the top of the hearing aid body is provided with a ridge, which can be clamped by the thumb and index finger, and then the hearing aid body is twisted to rotate and reel in the wire, and a toggle switch and an adjustment knob are provided on the ridge; a charging interface is provided at one end of the ridge; the adjustment knob is connected to a hearing aid circuit provided in the hearing aid body, and the hearing aid circuit is connected to a lithium battery module inside the hearing aid body through the toggle switch, and the lithium battery module is connected to the charging interface, the toggle switch is used to turn on and off the hearing aid, and the adjustment knob is used to adjust the volume.

[0009] Preferably, a first guide wheel and a second guide wheel are provided in the guide structure; and the headphone wire passes through between the first guide wheel and the second guide wheel.

[0010] Preferably, the earphone comprises an earphone body and an earplug; the earphone cable is plugged into a socket on one side of the earphone body through a plug; a mounting seat is provided on the top of the earphone body, and the mounting seat is sleeved with the mushroom-shaped earplug, so that the earphone and the earphone cable are detachable, and the earphone body and the earplug are detachable.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] This box-type wired hearing aid retracts and extends the headphone cord through a hearing aid body that can rotate in the shell. When patients of different heights wear it, they can adjust the length of the headphone cord according to their own length requirements to avoid the problem of the headphone cord being too long after wearing. After storage, the headphone cord is rolled up in the shell and is not easily bent and damaged, nor will it become tangled, making the hearing aid more convenient to use.
