Digital hearing aid

Abstract

The invention discloses a digital hearing aid comprising an ear mold device worn at the ear canal and a slender member device detachably connected with the ear mold device. The ear mold device is equipped with a receiver and a special hearing aid chip. The slender member device is equipped with at least one microphone and a microphone inlet hole. The receiver on the ear mold device and the microphone on the slender member device are connected through matching between a first socket arranged at one end of the ear mold device and a first plug arranged at one end of the slender member device so as to realize signal transmission. The digital hearing aid of the invention accords with the auricle shape of the human body, is small and light, and does not burden the auricle. The digital hearing aid integrates the advantages of both in-the-canal and behind-the-ear hearing aids. The ear blocking effect is reduced for users. The maximum non-squeak gain of the hearing aid is improved effectively. Convenience is provided in using and fitting.

Description

technical field [0001] The invention relates to a hearing aid, in particular to a digital hearing aid. Background technique [0002] At present, digital hearing aids are mainly divided into behind-the-ear type and ear canal type. [0003] The microphone, receiver, circuit, and dedicated DSP chip of the behind-the-ear digital hearing aid are all contained in the hearing aid's shell. The wearing method is to wear it behind the ear, that is, on the back of the ear. into the ear. [0004] The disadvantages of behind-the-ear digital hearing aids are: the shape is larger and more conspicuous, and it is easy to oppress the ear when worn for a long time. [0005] The other is the ear canal digital hearing aid. The microphone, receiver, circuit, and special hearing aid chip of the ear canal digital hearing aid are all contained in the ear mold shell, and the wearing method is to insert the ear mold device into the ear canal. The disadvantages of ear canal digital hearing aids are:...

[0004] The disadvantages of behind-the-ear digital hearing aids are: the shape is larger and more conspicuous, and it is easy to oppress the ears when worn for a long time

[0006] 1. The power is small. Since the microphone and the receiver are in the ear mold shell, the close distance between the two limits the maximum non-howling gain of the hearing aid;

[0007] 2. If the opening of the ventilation hole of the hearing aid is too large, it will easily produce howling, and if the opening is too small, it will cause a serious ear blocking effect;

[0008] 3. The small internal space of the hearing aid limits the function of the hearing aid and the selection of electronic devices, such as giving up volume control devices or program switching devices, etc.;

[0010] 5. Since the ear canal hearing aid is located in the human ear canal, it is inconvenient to plug and unplug the programming line when using the wired method to fit the hearing aid.
