Description

A new type of external microphone in-ear hearing aid

technical field

The utility model relates to the technical field of the second-class medical device hearing aid field, in particular to a novel in-ear type hearing aid with an external microphone.

Background technique

A hearing aid is a small amplification device for the hearing impaired to compensate for hearing loss. The basic structure of a hearing aid includes four main parts: a microphone, an amplifier, an earphone, and a power supply. The hearing aid converts the sound signal into an electrical signal (electrical energy) and sends it to the amplifier. The amplifier amplifies the weak input electrical signal, and then transmits it to the output transducer. The output transducer is composed of earphones or bone vibrators. Its function is to The amplified strong signal is converted from electrical energy to acoustic signal (sound energy) or kinetic energy for output. Therefore, the signal from the earphone or bone vibrator is much stronger than the signal originally received by the microphone, which can compensate the hearing loss of the hearing impaired to varying degrees.

Most of the existing hearing aids are in-the-ear hearing aids, but the output power of the in-the-ear hearing aids is not very high, and is only suitable for patients with mild, moderate, moderate and severe deafness, and is prone to whistling and friction due to its structural limitations. , resulting in impaired sound quality. To this end, we have launched a new type of external microphone in-ear hearing aid.

The inner end face of the casing is provided with a sound outlet, a receiver is installed in the casing and located at the sound outlet, and an earplug is installed on the inner end face of the casing and is located at the sound outlet.

Preferably, the outer end of the outer shell is large and the inner end is small.

Preferably, protrusions are integrally formed and connected to the outer side of the tuning knob at equal distances in the circumferential direction.

Preferably, the microphone, the tuning knob, the switch and the receiver are all electrically connected to a control module, and the control module is installed in the casing.

Preferably, the earplugs are soft rubber plugs.

Compared with the prior art, the beneficial effects of the present utility model are: the microphone of the present utility model adopts an external type, which makes it easier for the microphone to receive external sound information, and at the same time avoids the microphone and the receiver being integrally arranged in the casing, which may cause whistling and noise. fricative, thus affecting the sound quality. Insert the earplugs into the ears, turn on the switch to make the hearing aid work, adjust the volume through the tuning knob, and receive external sound information through the microphone. Separately set up to avoid whistling and fricative sound, and effectively ensure the sound quality. The sound signal received by the microphone is converted into an electrical signal and transmitted to the receiver. Can hear outside voices clearly.

Detailed ways

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the implementations. example. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

1-2, the present utility model provides a technical solution: a novel in-ear type hearing aid with an external microphone, comprising a housing 1, and a mounting post 2 is fixedly connected to the right side of the outer end surface of the housing 1. The mounting post 2. A microphone 3 is fixedly installed on the upper end, a circular hole is formed on the outer end surface of the outer casing 1 and located on the left side of the mounting column 2, and a tuning knob 4 is embedded in the circular hole, and a waist circle is opened at the lower end of the outer end surface of the outer casing 1 A switch 5 is embedded at the waist hole, a sound outlet is provided on the inner end face of the outer casing 1, a receiver is installed in the outer casing 1 and located at the sound outlet, and the inner end face of the outer casing 1 is located at the outlet. Earplugs 6 are installed on the sound outlet.

Specifically, the outer end of the outer shell 1 is large and the inner end is small, so that the smaller part of the inner end of the outer shell 1 can fit the user's ear canal to improve comfort, and the larger part of the outer end is located outside the ear canal, which acts as a fixed function to prevent the casing 1 from sliding into the ear canal as a whole.

Specifically, the outer side surface of the tuning knob 4 is integrally formed with protrusions 7 equidistantly in the circumferential direction, which plays an anti-slip effect and is convenient for the user to rotate the tuning knob 4 to adjust the volume.
