[0023] To further illustrate the various embodiments, the present invention provides drawings. These drawings are part of the disclosure of the present invention, which are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, a person of ordinary skill in the art should be able to understand other possible implementations and advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0024] The present invention will now be further described with reference to the accompanying drawings and specific implementation methods.

[0025] See also Figure 1 , 2 As shown in FIG. 1 , as a preferred embodiment of the present invention, a glasses-type hearing aid is provided, comprising a glasses body 3, on which a first hearing aid module 1 is provided, and the first hearing aid module 1 is arranged on a glasses leg 31 of the glasses body 3. The first hearing aid module 1 can be implemented by any existing hearing aid module, such as an air conduction hearing aid module or a bone conduction hearing aid module. The first hearing aid module 1 can be attached to the outer surface of the glasses leg 31, or can be built into the inner space of the glasses leg 31. In this embodiment, the first hearing aid module 1 is implemented by an air conduction hearing aid module, and the first hearing aid module 1 is implemented by a bone conduction hearing aid module. Figure 3 The first hearing aid module 1 includes a first receiver 11 and a first sound guide tube 12 built into the internal space of the glasses leg 31. A microphone (not shown) for picking up sound is provided on the glasses body. The sound picked up by the microphone can be amplified by the amplification circuit and then transmitted by the first receiver 11, and is transmitted to the ear canal through the first sound guide tube 12, the first sound outlet 13 provided on the glasses leg 31 and the air. Based on this, the position of the first hearing aid module 1 on the glasses leg 31 is adapted to the position of the human ear. The microphone picking up sound, the amplification processing of the sound by the amplification circuit, and the transmission of the sound in the hearing aid module can all adopt conventional technologies in the field and will not be repeated here.

[0026] The eyeglass body 3 is also attached with a second hearing aid module 2. In this embodiment, the second hearing aid module 2 is rotatably attached to the eyeglass leg 31, so that the second hearing aid module 2 can be rotated to adjust the position. The adjustable second hearing aid module 2 has at least a first position relatively close to the human ear and a second position relatively far from the human ear. Figure 1 and Figure 2 In the embodiment, a second hearing aid module 2 is respectively provided on two temples 31 of the eyeglass body 3, wherein the second hearing aid module 2 located on the temple 31 on the right side of the eyeglass body 3 is in its first position, and the second hearing aid module 2 located on the temple 31 on the left side of the eyeglass body 3 is in its second position, for ease of understanding. The second hearing aid module 2 may be provided with a locking mechanism at the first position and the second position, such as a buckle that can be engaged with the temple 31 is provided on the second hearing aid module 2, so that the second hearing aid module 2 can be stabilized in the first position or the second position without moving. In this embodiment, the rotating shaft of the second hearing aid module 2 has a certain rotation damping, so that the second hearing aid module 2 can be self-locking after being rotated into place.

[0027] The second hearing aid module 2 is another hearing aid module independent of the first hearing aid module 1 and has an independent hearing aid function. Similarly, the second hearing aid module 2 can also be made using the existing hearing aid principle. Figure 4 and Figure 5 The specific structure of the second hearing aid module 2 in this embodiment is shown. The second hearing aid module 2 is an air conduction hearing aid module, including a shell, a second receiver 21 and a second sound guide tube 22. The sound picked up by the microphone can be amplified by the amplification circuit and transmitted by the second receiver 21, and transmitted to the ear canal through the second sound guide tube 22, the second sound outlet 23 provided on the second hearing aid module 2 and the air. In order to ensure the best hearing aid effect, the second sound outlet 23 of the second hearing aid module 2 in the first position is exactly at the position of the ear canal opening of the human ear. The shell of the second hearing aid module 2 forming the second sound outlet 23 is a sound mouth structure that is tilted inward to align with the ear canal opening of the human ear.

[0028] When the second hearing aid module 2 is switched to the first position, the first hearing aid module 1 is turned off, and the second hearing aid module 2 is turned on, that is, the second hearing aid module 2 replaces the first hearing aid module 1 to perform the hearing aid work. In order to achieve this function, the glasses-type hearing aid also includes a detection device and a controller. The detection device is used to detect the second hearing aid module 2 in the first position and send a signal to the controller, and the controller controls the opening and closing of the first hearing aid module 1 and the second hearing aid module 2. If the detection device does not send a signal, the first hearing aid module 1 is turned on and the second hearing aid module 2 is turned off. If the detection device sends a signal, the first hearing aid module 1 is turned off and the second hearing aid module 2 is turned on.

[0029] Any detection device capable of detecting the position of the second hearing aid module 2 is feasible. In this embodiment, the detection device includes a first electrical contact portion 32 provided on the eyeglass body 3 and a second electrical contact portion 24 provided on the second hearing aid module 2. The second electrical contact portion 24 on the second hearing aid module 2 at the first position is connected to the first electrical contact portion 32, and the second electrical contact portion 24 on the second hearing aid module 2 at the second position is disconnected from the first electrical contact portion 32. Then, an electrical signal for detecting the position of the second hearing aid module 2 is generated by whether the first electrical contact portion 32 and the second electrical contact portion 24 are connected. In addition, the detection device can also be a proximity sensor provided on the second hearing aid module 2 and / or the eyeglass body 3, such as a photoelectric sensor, an ultrasonic sensor, a capacitive sensor, etc., which can generate a signal by changing the distance; or, the detection device can also be a mechanical switch provided on the second hearing aid module 2 / eyeglass body 3, such as a pressure-touch micro switch, a reed switch, etc. The first electrical contact portion 32 and the second electrical contact portion 24 used in this embodiment are simpler, more reliable and less expensive than other types of detection devices.

[0030] Through the above arrangement, the first hearing aid module 1 can be turned off and the second hearing aid module 2 can be turned on by adjusting the second hearing aid module 2 to the first position. Similarly, the first hearing aid module 1 can be turned on and the second hearing aid module 2 can be turned off by adjusting the second hearing aid module 2 to the second position, thereby realizing automatic switching of different hearing aids. In this embodiment, the power of the second receiver 21 is greater than that of the first receiver 11. In certain cases, the power of the second receiver 21 can also be less than that of the first receiver 11. The above design not only solves the problem that a high-power receiver cannot be used due to the small space of the temple 31 of the glasses, but also allows patients to choose a suitable receiver according to their hearing loss.

[0031] In this embodiment, the second hearing aid module 2 is connected to the eyeglass body 3 in a manner that it can rotate around a rotating shaft. In other embodiments, the second hearing aid module 2 can also be connected to the eyeglass body 3 in a slidable manner, or at least two mounting positions are provided on the eyeglass body 3, and the second hearing aid module 2 is detachably connected to the mounting position so that it can be switched between different mounting positions. For example, in one embodiment, two magnetic mounting positions are provided on the eyeglass body 3, and the second hearing aid module 2 is detachably magnetically assembled on the mounting position. That is, the second hearing aid module 2 can be connected to the eyeglass body 3 in a form in which the position can be adjusted. Preferably, the second hearing aid module 2 is detachably connected to the eyeglass body 3. It can be understood that the second hearing aid module 2 can be expanded in number, for example, two second hearing aid modules 2 are installed on one eyeglass leg 31, and the two second hearing aid modules 2 are respectively arranged at the front and rear positions of the first hearing aid module 1. When using, any second hearing aid module 2 can be selected and activated, and the receiver power or other functional specifications of the two second hearing aid modules 2 can be different. On the other hand, the second hearing aid module 2 can be configured as a modular structure that can be quickly installed and removed, and the user can select second hearing aid modules 2 of different specifications according to their needs to install them on the eyeglass body 3. The detachable and adjustable design of the second hearing aid module 2 increases the flexibility and adaptability of the product.

[0032] like Figure 1 In this embodiment, the second hearing aid module 2 in the second position is located in front of the human ear, so that the ear can be prevented from being interfered with when the second hearing aid module 2 is adjusted to the first position. In addition, the second hearing aid module 2 in the second position overlaps the temple 31 at least partially, so that the volume occupied by the second hearing aid module 2 can be reduced and the second hearing aid module 2 can be better hidden.

[0033] Figure 6 The circuit schematic diagram of this embodiment is shown in FIG.
