[0002] Glasses-type hearing aids are generally composed of a glasses body and a hearing aid mounted on the temples of the glasses body. Glasses-type hearing aids solve the disadvantage that it is not easy to wear glasses when wearing ear-hook hearing aids. At the same time, they have a better invisible effect and are not easy to lose.

[0003] However, the size of the temples is small and the installation space is also relatively small, which limits the function of the hearing aid. In particular, in order to improve the invisible effect, some existing hearing aids are built into the internal space of the temples, which makes it impossible for the hearing aids to use high-power receivers and cannot meet the different hearing compensation needs of patients.

[0023] To further illustrate various embodiments, the present invention is provided with accompanying drawings. These drawings form part of the disclosure of this invention and are primarily used to illustrate the embodiments and, in conjunction with the relevant description in the specification, to explain the operating principles of the embodiments. By referring to these drawings, those skilled in the art will understand other possible implementations and the advantages of this invention. The components in the figures are not drawn to scale, and similar reference numerals 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 Figure 1 、 2 As shown, 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. The first hearing aid module 1 is arranged on the temple 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 temple 31 or built into the inner space of the temple 31. In this embodiment, the first hearing aid module 1 is implemented by an air 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 is amplified by the amplification circuit and can be transmitted by the first receiver 11 and 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 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 to a second hearing aid module 2. In this embodiment, the second hearing aid module 2 is rotatably attached to the eyeglass temple 31, so that the second hearing aid module 2 can be rotated to adjust its 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 away from the human ear. Figure 1 and Figure 2 In the embodiment, a second hearing aid module 2 is provided on each of the two temples 31 of the eyeglass body 3. The second hearing aid module 2 on the temple 31 on the right side of the eyeglass body 3 is in its first position, while the second hearing aid module 2 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 can be provided with a locking mechanism in both the first and second positions, such as a buckle that can engage with the temple 31 to stabilize the second hearing aid module 2 in either the first or second position. In this embodiment, the rotating shaft of the second hearing aid module 2 has a certain degree of rotational damping, so that the second hearing aid module 2 can be self-locking after being rotated into position.

[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 detailed 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, comprising a housing, a second receiver 21, and a second sound conduit 22. Sound picked up by the microphone is amplified by an amplifier circuit and then transmitted through the second receiver 21. It then enters the ear canal through the second sound conduit 22, a second sound outlet 23 provided on the second hearing aid module 2, and air. To ensure optimal hearing aid performance, the second sound outlet 23 of the second hearing aid module 2, in its first position, is aligned with the opening of the ear canal. The housing of the second hearing aid module 2, which forms the second sound outlet 23, features an inwardly tilted mouthpiece structure to align with the opening of the ear canal.

[0028] When the second hearing aid module 2 is switched to the first position, the first hearing aid module 1 is turned off, while the second hearing aid module 2 is turned on. In other words, the second hearing aid module 2 now replaces the first hearing aid module 1 in providing hearing assistance. To achieve this function, the eyeglass-type hearing aid also includes a detection device and a controller. The detection device detects the second hearing aid module 2 in the first position and sends a signal to the controller, which controls the turning on and off of the first and second hearing aid modules 1 and 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 32 provided on the eyeglass body 3 and a second electrical contact 24 provided on the second hearing aid module 2. When the second hearing aid module 2 is in the first position, the second electrical contact 24 and the first electrical contact 32 are conductive, while when the second hearing aid module 2 is in the second position, the second electrical contact 24 and the first electrical contact 32 are disconnected. The conductive state between the first electrical contact 32 and the second electrical contact 24 generates an electrical signal for detecting the position of the second hearing aid module 2. Alternatively, the detection device may be a proximity sensor provided on the second hearing aid module 2 and / or the eyeglass body 3, such as a photoelectric sensor, ultrasonic sensor, or capacitive sensor that generates a signal based on changes in distance. Alternatively, the detection device may be a mechanical switch provided on the second hearing aid module 2 / eyeglass body 3, such as a pressure-sensitive microswitch or a reed switch. The use of the first electrical contact 32 and the second electrical contact 24 in this embodiment is simpler, more reliable, and less expensive than other types of detection devices.

[0030] With the above arrangement, adjusting the second hearing aid module 2 to the first position deactivates the first hearing aid module 1 and activates the second hearing aid module 2. Similarly, adjusting the second hearing aid module 2 to the second position activates the first hearing aid module 1 and deactivates the second hearing aid module 2, achieving automatic switching between different hearing aids. In this embodiment, the power of the second receiver 21 is greater than that of the first receiver 11. In certain circumstances, the power of the second receiver 21 can also be less than that of the first receiver 11. This design not only solves the problem of the limited space on the temple 31 preventing the use of high-power receivers, but also allows patients to choose the appropriate receiver based on their hearing loss.

[0031] In this embodiment, the second hearing aid module 2 is rotatably connected to the eyeglass body 3 about an axis. In other embodiments, the second hearing aid module 2 can also be slidably connected to the eyeglass body 3. Alternatively, the eyeglass body 3 may be provided with at least two mounting locations, to which the second hearing aid module 2 is detachably attached, allowing for switching between different mounting locations. For example, in one embodiment, the eyeglass body 3 is provided with two magnetic mounting locations, to which the second hearing aid module 2 is detachably magnetically attached. In other words, the second hearing aid module 2 can be attached to the eyeglass body 3 in an adjustable manner. Preferably, the second hearing aid module 2 is detachably connected to the eyeglass body 3. It is understood that the number of second hearing aid modules 2 can be increased. For example, two second hearing aid modules 2 can be installed on one eyeglass temple 31, with the two second hearing aid modules 2 positioned in front of and behind the first hearing aid module 1. During use, the user can select which of the second hearing aid modules 2 to activate. The two second hearing aid modules 2 can also have different receiver power or other functional specifications. On the other hand, the second hearing aid module 2 can be configured as a modular structure that can be quickly installed and removed. Users can choose second hearing aid modules 2 of different specifications according to their needs and 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 ear, which prevents interference with the ear when adjusting the second hearing aid module 2 to the first position. Furthermore, the second hearing aid module 2 in the second position at least partially overlaps with the temple 31, which reduces the volume of the second hearing aid module 2 and better conceals it.

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