Description

Technical Field

[0001] This utility model relates to the field of hearing aids, and in particular to a hearing aid and its vent structure. Background Technology

[0002] A hearing aid is a small amplifier that amplifies sounds that are otherwise inaudible. Utilizing the residual hearing of the hearing-impaired individual, the sound is transmitted to the auditory center of the brain, allowing them to perceive the sound. This brings great convenience to the hearing-impaired. However, existing hearing aids commonly suffer from the occlusion effect. This is mainly because when the vent of the hearing aid is closed, the low-frequency energy conducted by bone is reflected back into the ear canal, vibrating repeatedly in the cartilage of the external auditory canal. This amplifies the vibration of the tympanic membrane, causing the cochlea to perceive the sound as louder and more distorted, resulting in a feeling of "muffled blockage" or "echo." However, if the vent is opened to allow low-frequency energy to diffuse through the air and alleviate the occlusion effect, it can easily lead to bass frequencies leaking out, resulting in insufficient bass frequencies actually heard by the patient. Therefore, a balance needs to be struck between the occlusion effect and bass response of the hearing aid to provide the most suitable comfort for the patient. Utility Model Content

[0020] like Figure 1-5 A ventilation structure for a hearing aid includes: a hearing aid body 1, a solenoid valve 2, and a ventilation adjustment component 3; The hearing aid body 1 is provided with a vent hole 11, which passes through the inner ear end 101 at one end and the outer ear end 102 at the other end of the hearing aid body 1; the solenoid valve 2 is disposed in the vent hole 11. The ventilation regulating component 3 includes: a tap 31 and a baffle 32; The baffle 32 is rotatably mounted on both sides inside the vent hole 11, and an effective ventilation area 10 is formed between the baffle 32 and the inner wall of the vent hole 11; the adjusting pin 31 is rotatably and adjustablely mounted on the hearing aid body 1, with one end of the adjusting pin 31 located on the outer surface of the hearing aid body 1; the other end of the adjusting pin 31 extends into the hearing aid body 1 and is connected to the baffle 32 inside the vent hole 11; the adjusting pin 31 is used to adjust the size of the effective ventilation area 10.

[0021] This solution provides a vent structure for a hearing aid, wherein the vent 11 of the hearing aid body 1 is equipped with a solenoid valve 2, which can adjust the angle of the baffle 32 by adjusting the adjustment pin 31 on the outside of the hearing aid body 1, thereby adjusting the effective ventilation area 10 in the vent 11. This allows the effective ventilation area 10 of the hearing aid vent structure to be suitable for different patients, solving the problem of poor applicability caused by the inability to adjust the diameter of the vent structure of existing hearing aids.

[0022] Specifically, the hearing aid body 1 can be replaced by a known hearing aid structure, which generally consists of five parts: microphone, amplifier, receiver, power supply, and control components. The hearing aid body 1 is provided with a vent 11, which extends through the inner ear end 101 and the outer ear end 102 of the hearing aid body 1. Generally, the hearing aid body 1 has an earplug 17 at the inner ear end 101 and is exposed outside the ear at the outer ear end 102. The solenoid valve 2 is located in the vent 11. The solenoid valve 2 can be located inside the vent 11 or near the inner ear end 101 and the outer ear end 102. When the solenoid valve 2 is open, the vent 11 can be fully exposed. When the solenoid valve 2 is closed, the vent 11 can be closed. A baffle 32 is provided inside the vent 11. Both sides of the baffle 32 are rotatably disposed within the vent 11, and the baffle 32 is adjustable by an adjusting pin 31. The adjusting pin 31 extends from the outside to the inside of the vent 11, with one end of the adjusting pin 31 located on the outside of the hearing aid body 1. The patient or relevant personnel can adjust the rotation of the adjusting pin 31 from the outside of the hearing aid body 1, thereby rotating the baffle 32 connected to the other end of the adjusting pin 31. The baffle 32 is located inside the vent 11, and an effective ventilation area 10 is formed between the outer surface of the baffle 32 and the inner wall of the vent 11. In one embodiment, the adjusting pin 31 is connected to the middle of the baffle 32, such as... Figure 1 The two sides of the baffle 32 are close to the sidewalls of the vent hole 11. The upper and lower surfaces of the baffle 32 and the upper and lower walls of the vent hole 11 form an effective ventilation area 10. The baffle 32 can be adjusted to different angles. When the baffle 32 is adjusted so that the outer surface is close to the inner wall of the vent hole 11, the effective ventilation area 10 formed by the two gradually decreases. When the baffle 32 is adjusted so that the outer edge is away from the inner wall of the vent hole 11, the effective ventilation area 10 formed by the two gradually increases. When the baffle 32 is rotated to be parallel to the extension direction of the vent hole 11, the distance between the baffle 32 and the inner wall of the vent hole 11 is the largest, so the effective ventilation area 10 formed by the two is the largest, which is equivalent to the vent hole 11 being completely hollowed out. In this way, the angle of the baffle 32 at the vent 11 can be adjusted according to the patient's comfort, so that the angle of the baffle 32 is moderate, thereby avoiding the ear blockage effect caused by the effective ventilation area 10 being too small, and avoiding the problem of insufficient bass caused by the effective ventilation area 10 of the vent 11 being too large.

[0023] In one embodiment (not shown), when the adjusting pin 31 is connected to one end of the baffle 32, the effective ventilation area 10 can also be reduced when the other end of the baffle 32 is rotated to be close to the top or bottom wall.

[0024] Optimally, the inner wall of the vent hole 11 is provided with a shaft hole; one side of the baffle 32 is connected to the adjusting pin 31, and the other side of the baffle 32 is provided with a rotating shaft 33, the adjusting pin 31 and the rotating shaft 33 are coaxially aligned; the rotating shaft 33 is rotatably inserted into the shaft hole, and the adjusting pin 31 drives the baffle 32 to rotate around the rotating shaft 33.

[0025] The baffle 32 is rotatably disposed on the vent hole 11. One side of the baffle 32 is connected to the adjusting pin 31, and the other opposite side of the baffle 32 is provided with a rotating shaft 33. Since the adjusting pin 31 and the rotating shaft 33 are coaxially aligned, when the adjusting pin 31 drives the baffle 32 to rotate, the adjusting pin 31 and the rotating shaft 33 rotate coaxially, which can make the rotation of both sides of the baffle 32 smoother.

[0026] Optimally, the inner wall of the vent 11 is provided with a plurality of positioning grooves 12 within the rotation range of the baffle 32; The ventilation adjustment assembly 3 further includes: a positioning spring 34 and a positioning ball 35; The side of the baffle 32 is provided with a spherical groove 321, the opening of the spherical groove 321 is smaller than the diameter of the positioning ball 35, and the positioning ball 35 is disposed in the spherical groove 321; one end of the positioning spring 34 contacts the inner wall of the spherical groove 321; the other end of the positioning spring 34 contacts the positioning ball 35, and the positioning spring 34 elastically presses the positioning ball 35 against the opening of the spherical groove 321, so that the positioning ball 35 partially protrudes outside the opening of the spherical groove 321; when the baffle 32 rotates, the positioning ball 35 rotates to be positioned in a different positioning groove 12, so that the angle of the baffle 32 is fixed.

[0027] The inner wall of the vent 11 is provided with multiple positioning grooves 12, which are distributed within the rotation range of the baffle 32. The angle between the positioning grooves 12 is designed to be the angle between each rotation unit of the baffle 32. The limit of the baffle 32 at any positioning groove 12 corresponds to an effective ventilation area 10, the size of which is known. A spherical groove 321 is provided on the side of the baffle 32 facing the positioning groove 12. The positioning spring 34 of the spherical groove 321 presses the positioning ball 35 into the groove opening of the spherical groove 321. Because the opening of the spherical groove 321 is smaller than the diameter of the positioning ball 35, the positioning ball 35 cannot detach from the spherical groove 321, and a portion of the positioning groove 12 extends beyond the opening of the spherical groove 321. Therefore, when the baffle 32 rotates, the area of ​​the positioning ball 35 extending beyond the spherical groove 321 is confined to the positioning groove 12. Furthermore, when the positioning ball 35 enters or exits the positioning groove 12, the positioning spring 34 provides adaptive position adjustment for the positioning ball 35, allowing it to extend and retract within the opening of the spherical groove 321. In this way, the angle adjustment of the baffle 32 at the vent 11 is controllable, and the rotation of the baffle 32 can be decomposed into different rotation units, each corresponding to a fixed effective ventilation area 10, facilitating the selection of a suitable effective ventilation area 10 for different patients.

[0028] Alternatively, two adjacent positioning slots 12 can be connected by an arc groove 13, the arc groove 13 being coaxial with the rotating shaft 33; the positioning ball 35 can be transferred from one of the positioning slots 12 to the other positioning slot 12 via the arc groove 13.

[0029] When the positioning ball 35 switches between the two positioning slots 12, it passes through the arc groove 13 between the two positioning slots 12. The arc groove 13 is located within the rotation range of the baffle 32 and is coaxial with the rotating shaft 33. Therefore, when the positioning ball 35 switches from one positioning slot 12 to the other, it can directly enter the positioning slot 12. The positioning slot 12 can guide the positioning ball 35 to roll and guide the baffle 32 to rotate around the rotating shaft 33, thereby improving the smoothness of the baffle 32 in adjusting the effective ventilation area 10.

[0030] Optimally, the vent hole 11 is provided with a positioning platform 14 protruding from the inner wall, and the positioning platform 14 is located within the rotation range of the baffle 32; when the baffle 32 rotates to abut against the positioning platform 14, the positioning platform 14 restricts the baffle 32 from continuing to rotate, and the effective ventilation area 10 is maximized.

[0031] Positioning platform 14 is located at vent 11 and protrudes relative to the inner wall of vent 11. When baffle 32 rotates in the direction of increasing effective ventilation area 10, baffle 32 will eventually abut against positioning platform 14. At this time, effective ventilation area 10 is at its maximum, thus ensuring that the angle of baffle 32 can be directly positioned at the end of the rotation. At this time, positioning platform 14 restricts baffle 32 from continuing to rotate, and effective ventilation area 10 is at its maximum, which is the initial state of baffle 32. When calibrating effective ventilation area 10, calibration is generally started from the position where effective ventilation area 10 is at its maximum, that is, calibration starts from the initial state of baffle 32. Adjustment pin 31 drives baffle 32 to rotate away from positioning platform 14, so that effective ventilation area 10 gradually decreases, in order to help the patient find the most comfortable effective ventilation area 10.

[0032] Optimally, when one end of the baffle 32 is rotated to abut against the positioning platform 14, the effective ventilation area 10 is adjusted to the maximum; when the other end of the baffle 32 is rotated to abut against the bottom wall of the vent hole 11, the effective ventilation area 10 is adjusted to the minimum.

[0033] like Figure 2 When one end of the baffle 32 rotates clockwise toward the positioning platform 14, the effective ventilation area 10 gradually increases until the baffle 32 rotates to abut against the positioning platform 14. At this point, the baffle 32 is parallel to the central axis of the vent hole 11, and the effective ventilation area 10 is adjusted to its maximum. When the other end of the baffle 32 rotates counterclockwise away from the positioning platform 14, the effective ventilation area 10 gradually decreases until the other end of the baffle 32 abuts against the bottom wall of the vent hole 11. At this point, the effective ventilation area 10 is adjusted to close to 0, and the effective ventilation area 10 can be adjusted to its minimum.

[0034] Optimally, the ventilation adjustment assembly 3 includes: an adjustment wheel 36; The adjustment wheel 36 is located on the outside of the hearing aid body 1; the adjustment wheel 36 is sleeved on the tuning pin 31 and is used to drive the tuning pin 31 to rotate.

[0035] The adjusting wheel 36 is used to drive the adjusting pin 31 to rotate, which in turn drives the baffle 32 to rotate. The outer diameter of the adjusting wheel 36 is larger than that of the adjusting pin 31, which can increase the contact area and make it easier to manually twist and adjust.

[0036] Alternatively, the hearing aid body 1 may be provided with a receiver hole 15, which extends to the inner ear end 101; the hearing aid body 1 may be provided with a receiver 16 at the receiver hole 15; and the inner ear end 101 may be provided with an earplug 17.

[0037] The hearing aid body 1 has a receiver 16 at the receiver hole 15. One end of the receiver hole 15 opens into the inner ear 101. After the sound is amplified by the amplifier, the receiver 16 converts the electrical signal back into an acoustic signal, which is then fed back to the patient at the earplug 17. When the solenoid valve 2 is open, air can enter through the vent hole 11. The air and the sound signal from the receiver 16 at the receiver hole 15 are fed back to the patient's ear together, which can alleviate the patient's ear blockage effect. When the solenoid valve 2 is closed, air cannot enter through the vent hole 11, and the receiver 16 at the receiver hole 15 feeds back the sound signal to the patient's ear, which can concentrate low-frequency sounds.

[0038] Alternatively, the hearing aid body 1 may be provided with a control component 18, which is communicatively connected to the solenoid valve 2 and is used to control the opening and closing state of the solenoid valve 2.

[0039] The hearing aid body 1 is equipped with a control component 18, which can be a known control structure such as a button or touch key. The patient can control the opening and closing state of the solenoid valve 2 by controlling the control component 18, thereby controlling the opening and closing state of the vent 11, so as to open or close the pressure relief state as needed, thereby making the hearing aid biased to alleviate the occlusion effect or enhance the bass under certain circumstances.
