Description

Technical Field

[0001] This application relates to the field of hearing aids, and more particularly, to a hearing aid. Background Art

[0002] A hearing aid is a sound amplification device that helps hearing-impaired people improve their hearing and thus enhance their speech communication ability. With the development of microelectronics technology, hearing aids have become increasingly miniaturized. There are four basic types of hearing aids, namely: the behind-the-ear (BTE) type, the in-the-ear (ITE) type, the in-the-canal (ITC) type, and the completely-in-the-canal (CIC) type. Among them, the ITC type is customized according to the shape of the user's concha and ear canal, with good results and relatively concealed. Currently, high-power ITC hearing aids can be produced and are welcomed by the deaf. However, the ear mold of the current hearing aid often directly inserts the earplug part of the ear mold into the ear canal for assembly. However, the earplug part often over-seals the ear canal, preventing air flow and affecting the dissipation of sound waves generated by the hearing aid, thereby reducing the hearing aid effect.

[0003] Now a hearing aid is provided. Summary of the Utility Model

[0050] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0051] Refer to Figures 1 - 4 , a hearing aid, comprising: a hearing aid body, a rubber sleeve 12, and a rubber plate 26.

[0052] The hearing aid body includes: a housing 11, a processing chip 16, a receiver 15, a microphone 19, a battery compartment 17, and a compartment cover 18.

[0053] The processing chip 16 is installed inside the housing 11, the receiver 15 is installed inside the housing 11, the microphone 19 is installed on one end of the housing 11, the battery compartment 17 is installed on one end of the housing 11, and the compartment cover 18 is rotatably installed on one end of the housing 11 and closes the battery compartment 17. The processing chip 16 is electrically connected to the receiver 15, the battery compartment 17, and the microphone 19 respectively.

[0054] The rubber sleeve 12 is provided with a socket cavity 13, the rubber plate 26 is fixedly connected to the rubber sleeve 12, and the housing 11 is inserted into the socket cavity 13 so that the rubber sleeve 12 is sleeved on the housing 11. There are two through holes 14 which are symmetrically arranged on the rubber sleeve 12, and the two through holes 14 respectively penetrate through the rubber sleeve 12 and communicate with the socket cavity 13.

[0055] In order to ventilate the ear canal and the outside of the ear canal, two groups of symmetrically arranged air-permeable members are further provided, and the air-permeable members include: a rotating shaft 21, a baffle 20, and an adjusting turntable 22.

[0056] One end wall of the housing 11 is provided with a ventilation hole 24. The ventilation hole 24 is provided at one end of the housing 11 and penetrates through the other end of the housing 11. The ventilation hole 24 is an L-shaped hole. A rotation groove 23 is provided inside one end of the housing 11. The rotating shaft 21 is rotatably connected to the groove wall of the rotation groove 23. The baffle 20 is fixedly connected to the rotating shaft 21. The adjustment turntable 22 is fixedly connected to the rotating shaft 21. An adjustment groove 25 is provided on the end wall of the housing 11. The adjustment turntable 22 is rotatably connected inside the adjustment groove 25. The arc-shaped side wall of the adjustment turntable 22 is in sliding contact with the groove wall of the adjustment groove 25. The adjustment turntable 22 is made of rubber. There is friction between the arc-shaped side wall of the adjustment turntable 22 and the groove wall of the adjustment groove 25. The port of the ventilation hole 24 is located on the rotation path of the baffle 20. The ventilation hole 24 and the through hole 14 are correspondingly arranged, and the through hole 14 is communicated with the ventilation hole 24.

[0057] Working or installation process:

[0058] The housing 11 is sleeved inside the socket cavity 13 so that the rubber sleeve 12 covers the outer wall of the housing 11, and the two through holes 14 are respectively communicated with the two ventilation holes 24. When the rubber sleeve 12 and the housing 11 are inserted into the ear canal, when the housing 11 and the rubber sleeve 12 are inserted into the ear canal, the ear canal will be blocked, resulting in over-sealing of the ear canal and the air flow cannot flow. By providing the through hole 14 and the ventilation hole 24, and the through hole 14 is communicated with the ventilation hole 24, the internal space of the ear canal is communicated with the external space of the ear canal through the through hole 14 and the ventilation hole 24. By rotating the adjustment turntable 22, the adjustment turntable 22 drives the rotating shaft 21 to rotate, the rotating shaft 21 drives the baffle 20 to rotate, the baffle 20 rotates in a circular motion around its own axis of the rotating shaft 21, the baffle 20 rotates and moves towards the ventilation hole 24, and the baffle 20 continuously blocks the ventilation hole 24, thereby reducing the port of the ventilation hole 24 communicating with the external space of the ear canal until the baffle 20 completely blocks the ventilation hole 24, making the ventilation hole 24 closed; thus achieving the sound insulation effect inside the ear canal. Since the adjustment turntable 22 is made of rubber and is in rotational contact with the groove wall of the adjustment groove 25, there is friction between the baffle 20 and the adjustment groove 25. Without being affected by external human force, the baffle 20 will not rotate easily.

[0059] The above description is only some preferred embodiments of the present disclosure and an explanation of the applied technical principles. Those skilled in the art should understand that the scope of the invention involved in the embodiments of the present disclosure is not limited to the technical solutions formed by the specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the above inventive concept. For example, the technical solutions formed by mutually replacing the above features with the technical features (but not limited to) having similar functions disclosed in the embodiments of the present disclosure.
