[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] like Figs. 1 to 4 As shown, the first aspect of this utility model provides an adjustable earmold with an air hole 11, including: an earmold body 10, an air hole 11 through which the earmold body 10 is provided, a first end of the air hole 11 being located in the ear canal and a second end communicating with the outside, and an installation area being formed at the second end of the air hole 11; and an air hole adjustment component 20 disposed at the second end of the air hole 11.
[0032] Specifically, the air vent adjustment assembly 20 includes: a first adjustment plate 21 fixed to the ear mold body 10, and a second adjustment plate 22 rotatably connected to the first adjustment plate 21. The first adjustment plate 21 and the second adjustment plate 22 are fitted together to form a relative seal. The first adjustment plate 21 is provided with a first vent, and the second adjustment plate 22 is provided with a second vent. The second vent can partially or completely correspond to the first vent to achieve airflow or deviate from the first vent to prevent airflow.
[0033] The second end of the vent 11 is provided with a stepped hole 12 to form an installation area. The vent adjustment component 20 is embedded in the stepped hole 12. The first adjustment plate 21 is fixed on the stepped surface formed by the stepped hole 12. By setting the stepped hole 12, sufficient installation space is provided for the vent adjustment component 20, thereby improving the stability of the installation. The vent adjustment component 20 is embedded in the stepped hole 12, and the edge part of the first adjustment plate 21 overlaps with the stepped hole 12 and is bonded and fixed. Both the first adjustment plate 21 and the second adjustment plate 22 are circular, and the diameter of the second adjustment plate 22 is slightly smaller than the diameter of the first adjustment plate 21, or the two diameters are the same.
[0034] A rotating hole 211 is provided on the first adjusting plate 21, and a rotating shaft 221 adapted to the rotating hole 211 is provided on the second adjusting plate 22. The rotating shaft 221 is rotatably assembled in the rotating hole 211. The rotational connection between the second adjusting plate 22 and the first adjusting plate 21 is realized through the cooperation of the rotating hole 211 and the rotating shaft 221. A deformation groove 222 is provided in the middle of the rotating shaft 221, and a limiting protrusion 223 is provided at the end of the rotating shaft 221. When the limiting protrusion 223 passes through the rotating hole 211, it deforms inward. After passing through the rotating hole 211, the limiting protrusion 223 fits against the first adjusting plate 21. The deformation groove 222 provides deformation space during installation so that the rotating shaft 221 can pass through the first adjusting plate 21. The pressing of the limiting protrusion 223 against the first adjusting plate 21 can make the first adjusting plate 21 and the second adjusting plate 22 fit tightly together, realizing the relative sealing between the two.
[0035] Meanwhile, an adjustment groove 224 is provided in the middle of the outer side of the second adjustment plate 22. The adjustment hole facilitates the insertion of a fingernail or other special tool to rotate and adjust the position of the second adjustment plate 22. Since the overall size of the air hole adjustment component 20 is small, the adjustment groove 224 is set to be a micro-arc shape that allows the fingernail to be inserted for easy adjustment.
[0036] In some exemplary embodiments, the first vent includes: a first vent sub-port group 23 and a second vent sub-port group 24. The first vent sub-port group 23 includes a first number of first vent sub-ports, and the second vent sub-port group 24 includes a second number of second vent sub-ports. The areas of the first vent sub-ports and the second vent sub-ports are different. The second vent includes: a third vent sub-port group 25 corresponding to the first vent sub-port group 23 and a fourth vent sub-port group 26 corresponding to the second vent sub-port group 24. When the first vent sub-port group 23 and the second vent sub-port group 24 are completely aligned, the second vent sub-port group 24 and the fourth vent sub-port group 26 are offset. When the second vent sub-port group 24 and the fourth vent sub-port group 26 are completely aligned, the first vent sub-port group 23 and the third vent sub-port group 25 are offset, thereby enabling the adjustment of the vents 11 at different gradients.
[0037] The first vent group 23 and the third vent group 25 have the same number and shape, and the second vent group 24 and the fourth vent group 26 have the same number and shape. In a specific example, the first vent group 23 includes 5 oval first vents, and the second vent group 24 includes 3 oval second vents.
[0038] In use, sound is transmitted into the ear through the earmold 10. After being reflected in the ear canal, the sound escapes through the air hole 11 to prevent muffled sound. The sound is blocked when passing through the air hole adjustment component 20. By rotating the second adjustment plate 22, the relative position of the first air hole and the second air hole can be changed, that is, the overlapping area of the first air hole and the second air hole can be changed, thereby changing the air outlet area of the air hole 11. Users can rotate and adjust the position of the second adjustment plate 22 as needed to meet their own ventilation needs and adapt to the usage needs of patients with different hearing loss.
[0039] The second aspect of this utility model provides an earmold assembly, including: an adjustable earmold with air vent 11 as described in the first aspect, and a receiver. The receiver is connected to an external host via a wire. It is understood that an installation sleeve is provided inside the earmold body 10, and a receiver clip is installed inside the sleeve and extends to the front end of the earmold body 10.
[0040] The third aspect of this utility model provides a hearing aid, including: an earmold assembly as described in the second aspect, and an external host. The external host is used to receive and process external sound signals, and transmit the processed sound signals to the human ear via a receiver. The structure and function of the external host are prior art and will not be described in detail here.
[0041] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model. These are all equivalent modifications and improvements made to the above embodiments based on the essential technology of this utility model, and all of these fall within the protection scope of this utility model.
