Description

Technical Field

[0001] The present invention relates to the technical field of hearing aid devices, and in particular to a hearing aid device based on LE Audio. Background Art

[0002] LE Audio will utilize a new, low-complexity communication codec to achieve higher sound quality and lower power consumption. While LC3 codecs are inferior to aptX and aptX-HD audio codecs, they offer significant improvements in efficiency and quality compared to the classic Bluetooth audio codec, SBC. The application of LE Audio in Bluetooth hearing aids will bring benefits to the hearing-impaired. Its foundational features of low power consumption, high sound quality, and multi-streaming provide enhanced hearing aid support. Bluetooth audio already provides significant convenience for wireless calling, listening, and viewing for users worldwide. Similarly, all of the benefits of Bluetooth audio will be brought to the growing number of hearing-impaired individuals.

[0003] Hearing aids on the market are usually worn with the body stuck behind the ear, and the sound output of the hearing aid is inserted into the auricle. However, the hearing aid is worn by a clip-on method. The hearing aid has no external limiting structure, which can easily cause the hearing aid to fall off due to large movements of the person. Once the hearing aid falls off, the body will disintegrate, causing damage to the hearing aid. Hearing aids are expensive, and damage will increase the patient's usage costs.

[0009] Furthermore, the side seats on both sides of the inner rod are fixedly connected to the top rod, and the top rod between the side seat and the inner wall of the fuselage is connected to the second spring. One end of the second spring is disassembled and connected to the inner wall of the fuselage, and the other end of the second spring is disassembled and connected to the corresponding side seat end face.

[0010] Furthermore, the hook is provided with an inner opening, the inner opening is fixedly connected to the connecting rod, the inner opening is inserted into the outer side of the inner rod, the empty space on one side of the inner rod is slidably connected to the top seat, and a through opening is provided on one side of the inner rod.

[0014] Furthermore, the hinged head is located below the button, and a through slot is provided on the body corresponding to the button.

[0015] Furthermore, the through slot has the same shape as the button, and the button is slidably connected in the corresponding through slot.

[0016] Beneficial effects of the present invention:

[0017] The present invention is fixedly connected to a fixing seat inside the fuselage, and the fixing seat is fixedly connected to an inner rod, and the inner rod is slidably connected to a connecting rod, so that the connecting rod can slide on the inner rod, and one end of the connecting rod is connected to the corresponding inner opening of the hook, and the hook can slide through the connecting rod, and the hook can move away from or close to the fuselage. The end of the connecting rod inside the inner rod is fixedly connected to a push plate, and a first spring is sleeved on the connecting rod on one side of the push plate, and the first spring can realize the resetting of the connecting rod. When the hook moves outward, the top seat can push the push plate, and when the push plate moves, it can compress the connected first spring. When the top seat does not push the push plate, the first spring can drive the push plate to recover. When the hearing aid is placed behind the patient's ear, the hook is first extended outward by a button, and then the upper part of the ear is placed between the hook and the fuselage. Finally, when the button is released, the hook can be pushed by the first spring, and the hook can squeeze the upper part of the ear The cam is pressed between the body and the hook, and the torsion of the first spring is appropriate. The hook will not cause pain to the patient's ear when squeezed. The side edge of the push plate in the inner rod is fixedly connected to the side plate, and the side plate is fixedly connected to the top head. The top head can move with the movement of the push plate. When the push plate moves toward the inside of the body, it can drive the top head to move inward. The moving direction of the top head is slidably connected to the side seat, and the top head can push the side seat during the movement. The side seat can drive the push rod to move toward the outside of the body. The output end of the push rod is connected to the convex plate, and the convex plate is located on both sides of the body. The top head can open the convex plate to the outside, and the convex plate can be away from the outer end face of the body. When the hearing aid falls, the convex plate can be opened. After the convex plate is opened, the convex plate can first contact the falling position, so that the body is buffered by the convex plate, thereby preventing the body from falling directly, thereby avoiding damage to the body, thereby protecting the body and reducing the patient's use cost.

[0018] This solution is achieved by rotating a rotating rod on one side of the fixed seat, and a sector plate is fixedly connected to the rod body of the rotating rod, so that the sector plate can rotate along with the rotating rod. One end of the rotating rod is fixedly connected to an inclined frame, and the inclined frame is hinged to a linkage head, and the linkage head is hinged to a hinge head. The hinge head can be moved inward and outward by pressing a button. When the button is pressed downward, the linkage head can be pressed downward through the hinge head. When the linkage head moves downward, it can drive the inclined frame. When the inclined frame is driven, it can drive the rotating rod to rotate. When the rotating rod rotates, it can drive the sector plate to rotate. When the fan-shaped plate rotates, the top seat in the inner rod can be pushed. The outer rod is fixedly connected to the top seat. When the fan-shaped plate rotates, the outer rod can be squeezed. When the outer rod is compressed by the fan-shaped plate, it can move to one side of the inner rod. When the outer rod moves, it can also drive the top seat to move. When the top seat moves, it can push it. The top seat can move to the push plate position, and the top seat can push the push plate, thereby driving the connecting rod to move as a whole. When the connecting rod is pushed by the top seat, the hook outside the fuselage can be moved, thereby realizing the extension and retraction of the hook.

[0019] This solution uses an LE Audio Bluetooth transmitter module installed in the audio transmitter device to modulate the audio signal received by the audio transmitter device to generate a radio frequency signal and then transmit it; an LE Audio Bluetooth receiver module is installed in the body 1, which is used to receive the radio frequency signal and decode the radio frequency signal to obtain the radio frequency signal of the corresponding channel and modulate the radio frequency signal of the corresponding channel to generate the audio signal of the corresponding channel and then forward it. Therefore, the hearing aid device can receive various LE Audio sound sources such as TV, radio broadcasts, airport broadcasts, concert venues or speech workshops. BRIEF DESCRIPTION OF THE DRAWINGS
