[0009] The beneficial effect of this improvement is that when the device is used, the net sleeve is worn on the child's head and fixed to the child's jaw by sticking the two sets of Velcro on the chin straps to each other.

[0010] To improve the comfort of the device for children:

[0011] As a further improvement of the above technical solution: a silicone pad is provided at one end of the lower connecting seat located inside the mesh sleeve.

[0012] The beneficial effect of this improvement is that the provision of the silicone pad can improve the comfort of the child wearing the device.

[0013] To prevent the electrode block from falling out of the electrode socket:

[0014] As a further improvement of the above technical solution: an integrally formed limiting plate is provided on the side of the electrode block.

[0015] The beneficial effect of this improvement is that the limiting plate is used to limit the maximum extension length of the electrode block to prevent the electrode block from falling off from the electrode socket.

[0016] In order to transmit signals between the electrode block and the amplifier:

[0017] As a further improvement of the above technical solution: the top of the electrode socket is connected with the electrode wire harness.

[0018] The beneficial effects of the improvement are: the other end of the electrode wire harness is connected with the amplifier connector, for transmitting signals between the electrode block and the amplifier.

[0019] The parts not involved in the device are the same as or can be implemented by the prior art. BRIEF DESCRIPTION OF DRAWINGS
