Embodiment 1

[0084] The present invention also provides a state monitoring method for a bone conduction hearing device, the method comprising:

[0085] Step 1) The data acquisition module obtains in real time the input electrical impedance collected by the input electrical impedance detection circuit arranged on the bone conduction hearing device;

[0086] The magnitude of the input electrical impedance based on the collected bone conduction hearing device in the wearing state and the no-load state. Such as figure 2 As shown, the input electrical impedance of the bone conduction hearing device is basically fixed in one situation when it is unloaded, but in the wearing state, the input electrical impedance is no longer unified in a certain situation due to the different skull force impedances of different subjects. When different subjects wear the same bone conduction hearing device at the same position, the input electrical impedance is very close; and the input electrical impedance in t...

Embodiment 2

[0096] Step 1) The data acquisition module acquires the input electrical impedance collected by the input electrical impedance detection circuit arranged on the bone conduction hearing device in real time;

[0097] Based on the collected input electrical impedance of the bone conduction hearing device in the wearing state and the no-load state, the input electrical impedance of the bone conduction hearing device at no-load is basically fixed in one situation, but in the wearing state, the input electrical impedance is different due to different The subject's skull resistance varied and was no longer uniform to one situation. When different subjects wear the same bone conduction hearing device at the same position, the input electrical impedance is very close; and there is a significant difference between the input electrical impedance in the wearing state and the input electrical impedance in the no-load state.

[0098] Step 2) When the power coupling model and the correspondi...

Description

technical field [0001] The invention belongs to the technical field of audio communication and state monitoring of a bone conduction hearing device, and in particular relates to a state monitoring device and a monitoring method for a bone conduction hearing device. Background technique [0002] In order to protect the hearing health of the people, the independent technology development capabilities of hearing devices still need to be enhanced. The promotion of bone conduction hearing devices will become an effective supplement to traditional air conduction earphones, supporting hearing rehabilitation and technological advancement of wearable devices. Bone conduction hearing technology transmits external sound waves to the inner ear through the vibration of the skull, and then perceives the external sound. However, compared with the theoretical technology of air conduction earphones, the theoretical technology of bone conduction hearing devices is far from mature, and there ...
