Technical Field

[0001] The present invention relates to the technical field of hearing aids, and in particular to a hearing aid with automatic retractable earplugs and massage functions and a retractable control method. Background Art

[0002] In the development of hearing aid technology, how to ensure the fit of hearing aids in the ear canals of different wearers and improve the comfort of long-term wearing has always been the focus and difficulty of technical improvement. Traditional hearing aid earplugs are usually designed with fixed sizes, which leads to fit problems, especially for wearers with different ear canal shapes or sizes. Fixed-size earplugs often cannot provide ideal sealing effects and comfort.

[0003] In addition, wearing traditional hearing aids for a long time may also cause ear fatigue and discomfort, which not only affects the wearer's experience, but also may affect the hearing effect of the hearing aid. In order to seek a more comfortable wearing experience, some wearers may frequently adjust the position or tightness of the earplugs, but this manual adjustment is not only cumbersome, but also cannot ensure that each adjustment can achieve the best comfort and sealing.

[0004] Therefore, in order to solve the above-mentioned problems of earplug adaptability and wearing comfort, an innovative hearing aid design is urgently needed that can automatically adjust the size of the earplug in the ear canal of different wearers to ensure a wearing experience that is both tight-fitting and non-compressive. Summary of the invention

[0012] Based on the above-mentioned hearing aid with automatic retractable earplug and massage function, the present invention also provides a retractable control method of the hearing aid with automatic retractable earplug and massage function, comprising the following steps: Step S1, connecting the wireless terminal to the hearing aid; Step S2: the wireless terminal sends an air pressure increase instruction or an air pressure decrease instruction to the controller to control the extension and retraction of the earplug; Step S21, the wireless terminal sends an air pressure increase instruction to the controller, and the controller controls the micro air pump to inflate the closed space, so that the raised points on the outer rubber layer swell up, increasing the space between the inner rubber layer and the outer rubber layer. When the maximum comfort threshold is reached, it is recorded in the storage area of ​​the wireless terminal; Step S22, the wireless terminal sends an air pressure reduction instruction to the controller, and the controller controls the micro air pump to pump air into the enclosed space, thereby restoring the bulge on the outer rubber layer and reducing the space between the inner rubber layer and the outer rubber layer. When the minimum comfort threshold is reached, it is recorded in the storage area of ​​the wireless terminal.

[0013] Preferably, the expansion and contraction cycle of the earplug is 1 s, and the ratio of its expansion and retraction time is 1:2 to 2:1.

[0022] The technical solution of the present invention is further described below through the accompanying drawings and embodiments.

[0023] Unless otherwise defined, technical or scientific terms used in the present invention shall have the common meanings understood by one having ordinary skills in the field to which the present invention belongs.

[0024] Embodiment 1 like Figure 1-Figure 4 As shown, the present invention provides a hearing aid with automatic retractable earplug and massage function, comprising a control housing 1 and an earplug 2.

[0025] A plurality of ventilation holes 9 are provided on the control housing 1. The ventilation holes 9 ensure effective heat dissipation inside the hearing aid and avoid overheating problems that may occur during long-term use.

[0026] The control housing 1 contains components such as a Bluetooth transceiver 10, a power supply unit 12, and a controller 11. The power supply unit 12 provides stable power support for the entire hearing aid, while the Bluetooth transceiver 10 enables a convenient connection between the hearing aid and a wireless terminal (such as a smartphone). The controller 11 receives instructions from the wireless terminal and controls the coordinated work of various components.

[0027] The micro air pump 4 is also provided with a massage component on a side away from the flexible air tube 3. The massage component includes a massage motor 7, the output end of which is connected to a massage roller 8, which runs through the control housing 1. When the wearer needs a massage function, the controller 11 can start the massage motor 7 to drive the massage roller 8 to perform a gentle rolling massage on the back of the ear, thereby promoting blood circulation and relieving ear fatigue.

[0028] The earplug 2 is composed of an outer rubber layer and an inner rubber layer, and a closed space is formed between the outer rubber layer and the inner rubber layer. The closed space is connected to a micro air pump 4 in the control housing 1 through a flexible air tube 3. The function of the micro air pump 4 is to inflate or exhaust air in the closed space according to a control instruction, thereby changing the diameter of the earplug 2.

[0029] A plurality of raised points 5 are also provided on the outer rubber layer. The raised points 5 can better contact the ear canal wall when the earplug 2 is extended and retracted, which not only enhances the stability of the earplug, but also can massage the ear canal to a certain extent, thereby improving the wearing comfort.

[0030] The flexible air tube 3 is also equipped with a pressure sensor 6. The pressure sensor 6 can monitor the air pressure changes inside the earplug in real time and feed back the data to the controller 11. The controller 11 accurately adjusts the working state of the micro air pump 4 based on the feedback data and the PID (proportional-integral-differential) control algorithm to achieve fast and stable expansion and contraction adjustment of the earplug 2.

[0031] In actual application, the wearer can connect to the hearing aid through a wireless terminal (such as a smart phone). After the connection is successful, the wearer can send an air pressure increase command or an air pressure decrease command to the controller 11 through the wireless terminal. After receiving the command, the controller 11 will immediately start the micro air pump 4 to perform corresponding work, thereby changing the diameter of the earplug 2. When the earplug 2 reaches the comfort level expected by the wearer, the controller 11 will also record the air pressure value at this time in the storage area of ​​the wireless terminal for quick adjustment next time.

[0032] Embodiment 2 like Figure 5 As shown, a method for controlling the extension and retraction of a hearing aid with an automatically retractable earplug and a massage function comprises the following steps: Step S1: Connect a wireless terminal to the hearing aid; the wireless terminal may be a mobile phone or a tablet.

[0033] Step S2, the wireless terminal sends an air pressure increase instruction or an air pressure decrease instruction to the controller 11 to control the extension and retraction of the earplug 2; Step S21, the wireless terminal sends an air pressure increase instruction to the controller 11, and the controller 11 controls the micro air pump 4 to inflate the closed space, so that the raised point 5 on the outer rubber layer bulges, increasing the space between the inner rubber layer and the outer rubber layer. When the maximum comfort threshold is reached, it is recorded in the storage area of ​​the wireless terminal; Step S22, the wireless terminal sends an air pressure reduction instruction to the controller 11, and the controller 11 controls the micro air pump 4 to pump air into the enclosed space, so as to restore the bulging point 5 on the outer rubber layer and reduce the space between the inner rubber layer and the outer rubber layer. When the minimum comfort threshold is reached, it is recorded in the storage area of ​​the wireless terminal.

[0034] The expansion and contraction cycle of the earplug is 1s, and the ratio of its expansion and retraction time is 1:2~2:1.

[0035] In step S2, the wireless terminal sends an air pressure increase instruction or an air pressure decrease instruction to the controller to control the extension and retraction of the earplug. The specific operation is: ; in, For the Output value of secondary pressure control; For the Output value of secondary pressure control; is the proportional gain; is the integral gain; is the differential gain; For the Error in secondary pressure control; For the Error in secondary pressure control; For the The error of secondary pressure control.

[0036] In this embodiment, , and The values ​​are 0.9, 0.71 and 0.8 respectively.

[0037] It is worth noting that the contents not elaborated in detail in the present invention are all prior art and are well known to those skilled in the art.

[0038] Therefore, the present invention adopts the above-mentioned hearing aid with automatic retractable earplugs and massage functions and the retractable control method, which can not only automatically adjust according to the shape and size of the ear canals of different wearers to ensure a tight fit and non-oppressive wearing experience; it can also relieve ear fatigue and promote blood circulation through the intelligent massage function; at the same time, its precise pressure control and intelligent remote management functions also greatly improve the convenience and comfort of use.
