Actuator based on stimulating tympanic membrane and its hearing aid

Abstract

The invention discloses an actuator based on stimulating the tympanic membrane and a hearing aid device thereof. The actuator includes a piezoelectric mechanism, a fixed support device and an excitation film. A layer of excitation film is arranged on the top of the piezoelectric mechanism. The piezoelectric mechanism The tail end is fixedly arranged on the head end of the fixed support device, and the excitation membrane is implanted into the ear canal through the fixed support device and attached to the tympanic membrane. The fixed support device is supported on the ear canal by its branch support device; the actuation The hearing aid device of the present invention is constituted by a receiver, a microphone, a signal processing device, and a power supply device. The invention can directly excite the tympanic membrane, make the tympanic membrane vibrate, and compensate a relatively large degree of hearing damage, and its installation does not require complicated operation.

Description

technical field

[0001] The invention relates to an actuator for treating hearing loss and a hearing aid device using the actuator, which is used for directly exciting the tympanic membrane to compensate for hearing loss. Background technique

[0002] Sensorineural deafness is the most common type of hearing loss, and it is one of the most common diseases in my country. There are many reasons, such as congenital, high-intensity noise, etc. For some hearing-impaired patients, hearing aids can be used to improve or restore hearing, but traditional hearing aids have many problems: poor sound quality; only mild to moderate sensorineural hearing loss; output sound signals and ear canal feedback The sound signal of the patient is prone to aliasing, which reduces the clarity of the sound signal that the patient finally feels.

[0003] In response to the above problems, domestic and foreign research institutions and researchers have begun to study mechanically stimulated implantabl...

[0051] The present invention will be further described below in conjunction with the accompanying drawings.

[0052] Such as figure 1 It is a schematic diagram of the human ear structure, showing the cross sections of the outer ear 1 , the middle ear 2 and the inner ear 3 . Among them, the outer ear 1 mainly includes the auricle 4 and the ear canal 5; the middle ear 2 includes the tympanic membrane (eardrum) 6 and the ossicular chain. The ossicular chain consists of three tiny interconnected bones (ossicles), the malleus7, the incus8 and the stapes9. The malleus 7 is attached to the eardrum 6, while the stapes 9, the last bone in the ossicular chain, is coupled to the cochlea 10 of the inner ear. In the normal auditory system, the pinna 4 of the outer ear 1 collects pressure fluctuations in the external air, and transmits them to the tympanic membrane 6 through the ear canal 5, causing the vibration of the tympanic membrane 6 and the ossicular chain in the middle ear 2 syste...
