Full-band high-tone-quality hearing aid with sound beam and sound tunnels

Abstract

The invention discloses a full-band high-tone-quality hearing aid with a sound beam and sound tunnels. The hearing aid comprises a receiver, the receiver comprises a vibrating diaphragm, at least onesurface of the vibrating diaphragm is provided with a first groove and a second groove, the two grooves are crossed and communicated with each other, and the surface of the vibrating diaphragm is divided into four resonance areas; the diaphragm is also provided with a sound beam assembly at the center of the same side surface provided with the two grooves, and the sound beam assembly comprises a plurality of strip-shaped sound beam components which are arranged at the two sides of the first groove and the second groove in pairs; and the two grooves respectively form sound tunnels on the surface of the vibrating diaphragm. According to the invention, the vibrating diaphragm of the receiver is changed from the original free vibration mode to the current standard vibration mode, the problemsthat the high-pitch area of the receiver cannot be lighted and the low-pitch area is thick and round are solved from the angles of vibration, resonance and sound production, the fidelity of sound of each frequency band is improved, the noise interference is reduced, the real human voice is amplified, the sound quality is improved, and the hearing aid has the characteristics of high reduction of environmental sound. Practice proves that the improved design scheme has outstanding substantive features and remarkable technical progress.

Description

Technical field [0001] The invention relates to hearing aid equipment, in particular to a full-frequency high-quality hearing aid with a sound beam and a sound tunnel. The hearing AIDS include box type, behind-the-ear type, in-the-ear type, etc. technical background [0002] The hearing aid belongs to a small loudspeaker, which can enlarge the original inaudible sound for the hearing impaired, and then use the residual hearing of the hearing impaired to make the sound reach the brain auditory pathway of the hearing impaired and feel the sound. [0003] Generally, the structure of the hearing aid includes a microphone 1, an amplifier 2, a receiver 3 (also called a receiver), a volume regulator 4, a power supply 5, and a housing 6 (see Figure 1 ）。 The working principle of the hearing aid is that the sound signal is collected by the microphone 1, then converted into an electrical signal, and then amplified by the amplifier 2, and finally the amplified electrical signal is converted ...

AI Technical Summary

Problems solved by technology

[0006] The common problem of traditional hearing aid receivers is: the receiver has an inherent resonant frequency when making sounds. After exceeding a certain range of the resonant frequency area, the high-pitched area cannot be brightened, and the low-pitched area is not thick and round enough, resulting in the human voice being amplified at the same time. The noise in the sound will also be amplified, and the real ambient sound cannot be effectively restored, which will cause trouble for the hearing-impaired

The main reason is that the current receiver diaphragm cannot meet the good broadband vibration from the high-pitched range to the low-pitched range, that is, it cannot adapt to the resonance and vibration of the wide-ranging frequency changes in the high-pitched, mid-range, and low-pitched ranges at the same time.

In summary, the structural design of the traditional hearing aid receiver is unreasonable, which is not conducive to the good sound wave vibration of the diaphragm from the high-pitched range to the low-pitched range.
