Description

Technical Field

[0001] The present invention belongs to the technical field of hearing aids, and more particularly to an auxiliary visual display device for hearing-impaired persons. Background Art

[0002] Hearing-impaired persons may lose unilateral or bilateral hearing due to congenital or acquired reasons, resulting in the inability to normally receive sound signals in the environment. This not only affects interpersonal communication but also fails to react in real time to the source direction of sound signals or warning sounds in the environment. To facilitate the communication of hearing-impaired patients, the function of receiving language audio and converting it into text is usually adopted to assist hearing-impaired persons in solving the problem of receiving the voice communication of some normal people. However, there are still problems that need to be urgently solved in traditional auxiliary visual display devices for hearing-impaired persons.

[0003] For example, due to the visual limitations of hearing-impaired persons, communication can only be carried out when the two parties are face-to-face or within the field of vision. At the same time, the voice translation text display device or apparatus also needs to be within the field of vision to achieve this, resulting in the inability of hearing-impaired persons to react to other sound signals or warning sounds in the environment, seriously affecting their daily lives and even safety.

Detailed implementation mode

[0018] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation modes.

[0019] Combined with Figure 1 and Figure 3 As shown: An auditory impairment person-assisted visual display device described in an embodiment of the present invention includes: a temple 1 and a spectacle frame 4 arranged above the temple 1. A lens 5 is installed inside the spectacle frame 4, and an audio recognition piece 7 is arranged inside the spectacle frame 4. It further includes: A temple tail 2 and an azimuth calculation piece 64 are arranged below the temple 1. A touch switch 3 is installed inside the temple 1. An electric telescopic rod 31 is arranged inside the touch switch 3. A mounting block 6 is arranged inside the temple 1. An audio-visual mechanism is arranged inside the mounting block 6. The audio-visual mechanism is configured to convert an audio signal into a visual signal and display it on the lens 5. The audio-visual mechanism is arranged inside the temple 1 to convert an audio signal into a visual signal. A signal receiving mechanism is arranged inside the mounting block 6 to collect ambient audio signals.

[0020] During operation, when visual assistance is required to receive and identify audio or the meaning and orientation of language, the embodiment of the present invention is used. First, the device is worn on the ear. The audio recognition piece 7 recognizes the audio signal. Then, the touch switch 3 is activated by touching with a finger. The touch switch 3 drives the electric telescopic rod 31 to extend. The electric telescopic rod 31 extends to contact and activate the audio-visual mechanism. Then, the touch switch 3 is moved as a whole, so that the electric telescopic rod 31 moves accordingly and cooperates with the audio-visual mechanism. When the two cooperate, the audio signal, orientation, optical signal and visual signal are integrated by moving and squeezing methods, so as to facilitate the docking of the audio-visual mechanism with the received audio signal, so that the audio content and orientation are finally projected onto the screen of the lens 5 through the visual signal, thereby assisting hearing-impaired persons to hear sounds.

[0021] Such as Figures 4 to 6As shown in the figure: The voice and vision mechanism includes a display component, a fixing component, and a heating component. The display component is connected to the fixing component through a mounting block 6. The mounting block 6 is connected to the spectacle frame 4 through the heating component. The heating component is arranged inside the spectacle frame 4. The display component includes: An induction bar 61 penetrating inside the mounting block 6. An optical module 62 is sleeved on the outer periphery of the induction bar 61. A guide rail 63 is slidably connected to the bottom of the optical module 62. The guide rail 63 is located inside the mounting block 6. A voice module 65 is slidably connected above the guide rail 63. An orientation calculation component 64 is located between the voice module 65 and the optical module 62. A head-up display module 66 is arranged on the side of the voice module 65. The display component further includes: The induction bar 61 penetrates through the optical module 62, the orientation calculation component 64, and extends to the voice module 65. The guide rail 63 is fixedly connected inside the mounting block 6. The mounting block 6 contains a processor inside. A through groove adapted to the electric telescopic rod 31 is arranged on the induction bar 61.

[0022] During operation, when visual processing of the received voice information is required, the embodiment of the present invention is used. First, the voice signal is transmitted into the voice and vision mechanism by means of Bluetooth connection through the voice recognition component 7. After the touch switch 3 is activated, the electric telescopic rod 31 gradually extends. The electric telescopic rod 31 extends through the through groove of the induction bar 61. Then, the touch switch 3 is pulled by hand in the direction close to the temple 2. When the touch switch 3 moves, it drives the electric telescopic rod 31 to move synchronously. The movement of the electric telescopic rod 31 drives the voice module 65 to move in the direction of the temple 2 accordingly. When the voice module 65 moves, it gradually identifies the received voice signal. The voice module 65 gradually squeezes the orientation calculation component 64 and the optical module 62 to move along the upper side of the guide rail 63. When the orientation calculation component 64 and the optical module 62 move, they respectively feedback the source orientation of the surrounding voice signals and the optical signals of the near and far objects to the processor inside the mounting block 6. And when the voice module 65 moves, it drags the head-up display module 66 to move. After the head-up display module 66 moves, it deforms to gradually receive the voice signal and convert it into a visual signal. Furthermore, through the movement of the induction bar 61, it is ensured that the voice signal can identify the sound, identify the voice orientation, and convert the voice into visual content. And through the optical module 62, it is ensured that the display content is not affected by the user's visual focus. No matter whether the user observes near or far objects, the display content can be clearly displayed on the lens 5. Furthermore, it provides auxiliary processing for hearing-impaired persons, promotes the reception of sound, and facilitates the communication of users.

[0023] As Figures 6 to 8 As shown in the figure: The signal receiving mechanism includes a voice expansion component and an anti-obstruction component. The voice expansion component is connected to the mounting block 6; The anti-obstruction component is located outside the voice expansion component. The voice expansion component includes: An orientation calculation component 64 arranged inside the temple 1; Two moving frames 641 are slidably connected inside the orientation calculation component 64; A signal enhancement cylinder 642 is provided on the side of the movable frame 641; the anti-obstruction component includes an annular bladder 643, a transmission strip 644 is connected through the inner top wall of one of the movable frames 641, and a plurality of spray columns 645 are provided on the outer periphery of the annular bladder 643; the transmission strip 644 penetrates the movable frame 641 and contacts the spectacle frame 4, facilitating the transmission of audio signals to the lens 5 inside the spectacle frame 4, and an audio signal hole for receiving audio signals is provided on the side of the temple 1.

[0024] During operation, when receiving and processing audio signals, the audio signals need to be received through the audio signal holes provided on the side of the temple 1. During use, the audio signal holes are very likely to be contaminated with a lot of dust due to long-term static placement or improper protection, resulting in the audio signals being blocked by the dust during transmission, causing the problem of slow reception of audio signals. Using the embodiment of the present invention, the electric telescopic rod 31 drives the audio module 65 to move and squeeze the azimuth calculation member 64 to work. The azimuth calculation member 64 deforms, and the movable frame 641 gradually moves under the action of the deformation. After the movable frame 641 moves, it pushes the signal enhancement cylinder 642 to move. When the signal enhancement cylinder 642 moves, it gradually enhances the intensity of the received audio signal, which is beneficial to improving the effect of receiving audio signals; At the same time, the movement of the movable frame 641 will squeeze the annular bladder 643 to move. The gas contained in the annular bladder 643 is blown out through the spray columns 645. When the gas passes through the audio signal holes provided on the side of the temple 1, the dust inside is removed, thereby assisting in improving the reception of audio signals; it should be noted that the spray columns 645 are flush with the positions of the audio signal holes.

[0025] As Figures 9 to 10 shown: The fixing component includes: an impact ball 21 fixedly installed inside the temple end 2, an elastic connection strip 23 is provided on the side of the impact ball 21, a rolling disc 22 is fixedly connected to the end of the elastic connection strip 23, a docking strip 20 is fixedly connected to the side of the rolling disc 22, a curve groove and a locking groove are provided inside the temple end 2, a hook body 24 is installed inside the curve groove, the curve groove is used to facilitate the sliding of the hook body 24, and the locking groove is used to cooperate with the hook body 24 to form a clamping position; the fixing component further includes: the hook body 24 is connected to the rolling disc 22, a recessed groove adapted to the impact ball 21 is provided inside the temple end 2, a soft clamping strip is provided on the side of the hook body 24, the soft clamping strip is used to be clamped in the locking groove of the temple end 2 to prevent falling off, and a friction piece is provided at the bottom of the hook body 24. The adjusting part is located inside the temple end 2 and is connected to the fixing component. The friction piece ensures that when contacting the ear, the sliding effect can be reduced, preventing it from slipping easily.

[0026] During operation, since hearing-impaired patients sometimes wear hearing aids for assistance, when the hearing aid and the wearable device share the same ear, it often occurs that the two devices rub against each other and are prone to falling off. When using the embodiment of the present invention, when the touch switch 3 moves towards the direction close to the mirror tail 2, it will push the docking strip 20 to work. When the docking strip 20 works, it will squeeze the rolling disc 22 to move. The rolling disc 22 slides from high to low along the curve groove and impacts the hook body 24 to move. The hook body 24 gradually extends from under the mirror tail 2. At this time, the soft clamping strip of the hook body 24 is clamped into the locking groove of the mirror tail 2. After extending, the hook body 24 gradually forms a semicircle to hook the ear, improving the clamping stability and avoiding the situation of slipping due to jitter when the two devices rub against each other; it should be noted that the diameter of the rolling disc 22 is larger than the diameter of the impact ball 21, and the weight of the rolling disc 22 is heavier than the weight of the impact ball 21. The elastic connecting strip 23 is used to connect the impact ball 21 to prevent the impact ball 21 from being disconnected from the rolling disc 22.

[0027] As Figure 11 shown, the adjusting part includes: a positioning column 244 installed on the side wall of the hook body 24. A connecting strip 243 is fixedly connected to the side of the positioning column 244. A torsion disc 242 is wound around one end of the connecting strip 243 away from the positioning column 244. A support rod 241 is inserted into the center of the torsion disc 242; the support rod 241 is rotatably connected to the inside of the mirror tail 2; During operation, since the sizes of people's ears are different, it is easy to have inaccurate clamping during fixation. When it is necessary to adjust it to ensure accurate clamping, when using the embodiment of the present invention, at this time, the support rod 241 is rotated counterclockwise by hand. After the support rod 241 rotates, it squeezes the connecting strip 243 to move. The connecting strip 243 squeezes the positioning column 244 to move. The positioning column 244 gradually swings and bends the angle under the action of the rotational force. After the angle of the hook body 24 bends, it is easier to accurately clamp into the user's ear; it should be noted that there is a gap between the soft clamping strip of the hook body 24 and the locking groove, which can meet the condition of appropriate fine-tuning of the soft clamping strip of the hook body 24 in the locking groove, avoiding it being difficult to fine-tune the bending angle of the hook body 24 because the two are completely sealed.

[0028] As Figures 12 to 14 shown, the heating component is arranged inside the spectacle frame 4, in the direction of the lens 5 close to the temple 1. The heating component includes a heating wire 41. A conduction piece 42 is arranged in the inner cavity of the heating wire 41, and a trigger strip 43 is arranged on the side of the heating wire 41.

[0029] During operation, when it is necessary to perform visual processing of audio signals on a rainy day, the lens 5 is easily adhered to by rainwater. After the rainwater wets the lens 5, it affects the clarity. When using the embodiment of the present invention, after the head-up display module 66 deforms, it contacts the trigger strip 43. The trigger strip 43 works to drive the heating wire 41. The heating wire 41 works to remove the rainwater through the conduction piece 42, thereby improving the visual effect of the clear lens 5.

[0030] The electric telescopic rod 31 drives the moving frame 641. When the moving frame 641 squeezes the annular bladder 643 and moves, it blows out gas to remove the dust in the sound signal holes, thereby assisting in improving the reception of sound signals. At the same time, the moving frame 641 drives the anti-obstruction component to move, which is beneficial to improving the signal strength of the received sound signals.

[0031] Working principle: Overall overview: This auxiliary visual display device is designed to convert sound signals into visual signals for people with hearing impairments to assist them in obtaining sound information. The device mainly consists of temple arms 1, a spectacle frame 4, lenses 5, a sound signal identification component 7, a sound signal visual mechanism, a signal receiving mechanism, a fixing component, a heating component, etc. Each component works together to achieve the collection, conversion, and display of sound signals. Wearing and starting: The user wears the device on the ear, and at this time the device is in the initial standby state. When it is necessary to receive and identify sound signals or the meaning and direction of language with the help of visual assistance, the user touches the touch switch 3 on the inner side of the temple arm with a finger to start the device working process. After the touch switch 3 is triggered, it drives the electric telescopic rod 31 to extend. The electric telescopic rod 31 extends to contact and start the sound signal visual mechanism, preparing for the subsequent signal processing process. Collection and transmission of sound signals: The sound signal expansion component in the signal receiving mechanism is responsible for collecting ambient sound signals. Sound signal holes are provided on the side of the temple arm 1, and external sound signals enter through them. The two moving frames 641 inside the azimuth calculation component 64 play a role when the device is working. The electric telescopic rod 31 drives the sound signal module 65 to move and squeeze the azimuth calculation component 64, causing it to deform, and then pushing the moving frame 641 to move. When the moving frame 641 moves, the signal enhancement cylinder 642 on the side moves synchronously to enhance the intensity of the received sound signals and improve the sound signal collection effect. At the same time, the movement of the moving frame 641 squeezes the annular bladder 643, and the gas in the annular bladder 643 is blown out through the spray column 645 to remove the dust in the sound signal holes, ensuring that the sound signal transmission is not blocked by dust, assisting in improving the sound signal reception effect, and the collected sound signals are transmitted into the sound signal visual mechanism through Bluetooth connection.

[0032] Conversion of sound signals into visual signals: After receiving the audio signal, the audio-visual mechanism starts to process. The electric telescopic rod 31 extends through the through groove of the induction strip 61. The user manually pulls the touch switch 3 and moves it towards the mirror tail 2, driving the electric telescopic rod 31 and the audio module 65 to move synchronously. During the movement, the audio module 65 gradually identifies the received audio signal and simultaneously squeezes the azimuth calculation component 64 and the optical module 62 to move above the guide rail 63. The azimuth calculation component 64 feeds back the source azimuth of the surrounding audio signals to the processor inside the placement block 6, and the optical module 62 also feeds back the optical signals of the near and far objects to the processor. The movement of the audio module 65 will also drag the head-up display module 66 to move. After the head-up display module 66 moves, it deforms and gradually receives the audio signal and converts it into a visual signal. The induction strip 61 moves during this process to ensure that the audio signal can achieve voice recognition, audio azimuth identification, and conversion into visual content. The optical module 62 ensures that the display content is not affected by the user's visual focus. Whether the user observes near or far objects, the visual signals of the final audio content and azimuth can be clearly projected onto the screen of the lens 5, completing the conversion from the audio signal to the visual signal and assisting hearing-impaired people in obtaining sound information. Device Fixation and Adjustment: The fixing component is used to ensure the stable wearing of the device on the user's ear. When the touch switch 3 moves towards the mirror tail 2, it pushes the docking strip 20 to work, and the docking strip 20 squeezes the rolling disc 22 to move. The rolling disc 22 slides from high to low along the internal curve groove of the mirror tail 2 and impacts the hook body 24 to move, causing the hook body 24 to extend from below the mirror tail 2. At this time, the soft card strip of the hook body 24 is stuck into the locking groove of the mirror tail 2, forming a semi-circular shape to hook the ear, improving the clamping stability of the device and avoiding dropping due to friction and squeezing with other ear devices such as hearing aids. For the differences in the ear sizes of different users, the adjusting parts can adjust the fixing angle of the device. The user rotates the support rod 241 counterclockwise. The support rod 241 rotates and squeezes the connecting strip 243 to move, and the connecting strip 243 then squeezes the positioning column 244, causing the positioning column 244 to drive the hook body 24 to change the bending angle and more precisely fit into the user's ear. The gap between the soft card strip of the hook body 24 and the locking groove provides conditions for fine-tuning the bending angle of the hook body 24. Lens 5 Cleaning Assistance: When using the device on a rainy day, the lens 5 is likely to be affected by the adhered rainwater and affect the clarity. When the head-up display module 66 deforms and contacts the trigger strip 43 in the heating component, the trigger strip 43 drives the heating wire 41 to work. The conduction piece 42 in the inner cavity of the heating wire 41 transfers the heat to remove the rainwater on the lens 5, improving the visual effect of the lens 5 and ensuring that the visual content after the conversion of the audio signal can be clearly displayed, meeting the user's usage requirements in a rainy environment.
