[0022] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present utility model clearer and more understandable, the following further details the present application in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0023] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present application.

[0024] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, the meaning of "a plurality" is two or more, unless otherwise specifically defined.

[0025] Reference to "an embodiment" or "embodiments" throughout the specification means that a particular feature, structure, or characteristic described in connection with the embodiments is included in at least one embodiment of the present application. Thus, the phrases "in an embodiment" or "in some embodiments" appearing throughout the specification are not necessarily all referring to the same embodiment. Moreover, in one or more embodiments, the particular features, structures, or characteristics may be combined in any suitable manner.

[0026] See Figure 1 , the present utility model provides a multifunctional hearing aid, including a hearing aid main body 10, a receiver 20, and a sound guiding tube ear hook 30 connecting the hearing aid main body 10 and the receiver 20. The sound guiding tube ear hook 30 is a transparent bendable tube so as to be better bent into a shape conforming to the ear contour during wearing, and a second-order bowl-shaped silicone ear cap 201 is detachably arranged on the receiver 20.

[0027] See Figure 1, a multi-functional sensor 40 is provided on the ear-attached side of the hearing aid main unit 10. The multi-functional sensor 40 includes a wearing detection sensor, a blood oxygen detection sensor, and a heart rate detection sensor; the wearing detection sensor is used to detect the wearing condition of the hearing aid main unit 10 to assist the hearing aid main unit 10 in powering on when worn and powering off when not worn; the blood oxygen detection sensor and the heart rate detection sensor are used to collect blood oxygen data and heart rate data of the ear back at the wearing position respectively. The wearing detection sensor can be an infrared distance sensor. The utility model can identify whether the machine is worn by adding a wearing detection sensor. When it is detected that the wearing is completed, the hearing aid will power on. When not worn, the hearing aid will not power on and will not generate howling.

[0028] The blood oxygen detection sensor is based on the photoplethysmography technology (light (red light or infrared light) penetrates the skin and is received by the receiving device. The intensity of the received light changes with the heartbeat and blood circulation. By analyzing these changes, the blood oxygen saturation can be calculated), and reflects the blood oxygen level of the human body by measuring the oxygen saturation of the blood in human tissues.

[0029] The heart rate detection sensor is also based on the photoelectric measurement method. The heart rate sensor places an LED light source above the skin and guides the light into the skin tissue. When the light penetrates the skin, a part of it will be absorbed by the skin, and the other part will be reflected back to the sensor. The heartbeat will cause a change in the blood volume in the skin. When the heart beats, the blood volume increases, resulting in an increase in the amount of light absorbed; on the contrary, when the heart relaxes, the blood volume decreases, and the amount of light absorbed decreases. By analyzing the peaks in the signal, the heartbeat cycle of the heart can be determined and the heart rate can be calculated.

[0030] See Figure 2 , in an alternative embodiment of the present utility model, the hearing aid main unit 10 includes a housing 70 composed of an ear-attached side bottom shell 50 and a back-ear side shell 60 (connected by hooks), a device fixing bracket 80 arranged in the housing 70, a sensor driving board 90, a hearing aid main board 100, a pickup 110, and a power supply module 120 mounted on the device fixing bracket 80, and a sound generating unit 130 mounted at the sound output end of the housing 70.

[0031] See Figure 1 and Figure 2, in an optional specific example of the present utility model, the outer shape of the housing 70 is designed as a tama (comma) shape, the sound generating unit 130 is connected to the tip (tail) end of the hook of the housing 70, and the device fixing bracket 80 is correspondingly designed to be a tama (comma) shape that can be accommodated inside the housing 70. The device fixing bracket 80 includes a hook head section and a hook tail section. One end (i.e., the hook tail section) of the device fixing bracket 80 close to the sound generating unit 130 is separated by a partition 801 to form a main board card slot and a drive board card slot. The hearing aid main board 100 is installed in the main board card slot and faces the back ear side shell 60, the sensor drive board 90 is installed in the drive board card slot and faces the ear-attached bottom shell 50, and the multi-functional sensor 40 is installed on the ear-attached bottom shell 50.

[0032] See Figure 2 , on one side of the hearing aid main board 100 facing the back ear side shell 60, there is a boat-shaped button switch 101.
