Problems solved by technology

Therefore, even if the speaker power is strong, the speaker power, that is, the hearing aid power, will lose up to 30%, reducing the use effect
Many patients with severe hearing loss complain that BTE hearing aids have low power
When the speaker is too close to the eardrum, it is easy to produce resonance

Embodiment Construction

[0032] Such as figure 2 Shown, a kind of hearing aid 6 of hearing-in-the-ear hearing aid 6 comprises horn 5, and on described horn 5, passes flexible pipe 2 (such as image 3 shown) is connected with a device that strengthens the power of the speaker 5 in the ear, and the device that strengthens the power of the speaker 5 in the ear is an air duct 1, and the air duct 1 is placed near the Eustachian tube of the middle ear, so that the The hearing aid sound signal is delivered directly to the tympanic cavity close to the middle ear and the tympanic membrane and auditory ossicles.

[0033] To prevent sound pressure leakage along the periphery; provide an air flow channel near the center of the ear canal to prevent occlusion effects; support and fix the horn and air tube 1 to prevent loosening or dislocation, vibration and resonance; soft and comfortable to wear; easy to replace or Clean up earwax, etc.; easy to place and take out, the air duct 1 is provided with earplugs 3 , an...

Abstract

The invention discloses an ear-carried type hearing aid (6) for receiving sound in ears, comprising loudspeakers (5). Air conduits (1) are connected to the loudspeakers (5) through flexible tubes (2) and are arranged nearby Eustachian tubes of middle ears. The hearing aid solves the problem of signal attenuation when signals are transmitted to eardrums, changes the traditional mode of improving the received sounds of users by improving the qualities of signals into the mode of adding the air conduits (1) by changing a structure under the premise of ensuring the wearing comfortableness of the users to directly transmit the sound signals to the eardrums from external auditory canals, thereby the users can obtain higher power effect, the power of the ear-carried type hearing aid for receiving sound in ears is improved by above 20%.

Description

technical field [0001] The invention relates to a device for enhancing the power of a speaker for in-ear speech, and in particular to a behind-the-ear (BTE) hearing aid for in-ear speech. The hearing aid enhances in-ear speech by improving its structure. Background technique [0002] At present, most manufacturers of hearing aids are making a fuss about improving the output signal of hearing aids, suppressing environmental noise, and sound reflection signals to ensure the quality of the output signal. But they ignore an important factor: even if the quality of the output signal is very good, but the part received by the user is very small, the user cannot obtain better results. For example, the Chinese patent application No. 200810089520.9 and the US patent US2004 / 0190734 are aimed at obtaining higher quality output signals. [0003] There are two types of hearing aids on the market: over-the-ear (i.e., behind-the-ear, BTE) and in-ear (CIC). Such as figure 1 As shown, the...
