Abstract
Description
Technical Field
[0001] This utility model relates to the field of hearing aid technology, specifically to a bone conduction hearing aid. Background Technology
[0002] Bone conduction hearing aids are a special type of hearing aid. Normally, sound travels through the external auditory canal, causing the eardrum to vibrate, and then the vibrations are transmitted to the inner ear via the ossicles and other structures. Bone conduction hearing aids, however, work based on the principle of bone conduction. They directly convert sound into vibration signals, which are then transmitted to the inner ear (cochlea) through the skull.
[0003] For example, when a bone conduction hearing aid receives a sound signal, its internal vibrator generates a mechanical vibration corresponding to the sound. This vibration causes a tiny vibration in the skull, just as we can feel vibration when we touch a sound-producing object. The vibration of the skull directly stimulates the auditory receptors in the inner ear, enabling the patient to perceive sound.
[0004] The signal receiver of existing bone conduction hearing aids is generally hung on the ear. It mainly adopts a shape that matches the ear canal, making it easy to wear. However, when using this type of bone conduction hearing aid, it is easy to leave sweat stains and is not easy to clean. This is mainly because the signal receiver is in direct contact with the skin, and the circuit is relatively long, which can cause the circuit to shake during use, affecting its use. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model proposes a bone conduction hearing aid.
[0006] The technical solution of this utility model is a bone conduction hearing aid, comprising a receiver, a silicone wire sleeve connected to one side of the receiver, a data cable connected to the receiver being disposed inside the silicone wire sleeve, and an earplug connected to the data cable, and further comprising:
[0007] A fin limiting mechanism is detachably connected to the receiver, and the fin limiting mechanism partially encloses the receiver. The outer surface of the fin limiting mechanism is provided with an inwardly concave arc-shaped surface.
[0008] A line organizing mechanism is disposed at the tail of the receiver, and a portion of the line organizing mechanism is exposed at the tail of the receiver.
[0009] The cable management mechanism includes a circular take-up compartment, inside which is a take-up reel, and the end of the data cable is wound around the take-up reel.
[0010] Furthermore, the earplug includes a mushroom-shaped cap with a plug body inside, the cap and plug body being integrally formed, the cap having multiple deformation holes, and the head of the cap having a sound channel hole.
[0011] Furthermore, the fin limiting mechanism includes an inner fin and an outer fin, the inner fin and the outer fin are integrally formed in the middle, and a compression cavity is provided between the inner fin and the outer fin.
[0012] Furthermore, the silicone wire sleeve includes a connecting root, which snaps into a slot provided in the receiver housing.
[0013] Furthermore, the data cable includes a protective sleeve and a cable disposed inside the protective sleeve, the cable being connected to internal components, and one end of the protective sleeve being fitted onto the take-up reel.
[0014] Furthermore, the cable management mechanism also includes a damping surface disposed on the inner wall of the circular take-up compartment. An arc-shaped slide rail is disposed on the circular take-up compartment, and a sliding plate is slidably connected to the arc-shaped slide rail. A turntable is rotatably connected to the inner wall of the circular take-up compartment, and the take-up wheel is fixedly connected to the turntable. A connecting strip is fixedly connected to the sliding plate, and the connecting strip passes through the circular take-up compartment and rotates on the turntable shaft. A gear is fixedly connected to the turntable, and a half gear is fixedly connected to the connecting strip.
[0015] This utility model has the following beneficial effects:
[0016] 1. The inner and outer fins are integrally formed in the middle, which fixes the formed part to the receiver. The installation method is a snap-fit, which allows it to be removed at any time when adjustment is needed;
[0017] The inner and outer fins are wing-shaped and converge upwards from the receiver to clamp and wrap around it. The advantage of this design is that the inwardly concave arc surface of the outer fin can fit snugly against the ear, thus improving the stability of wearing it. Furthermore, pressing the outer fin in opposite directions makes it easy to remove.
[0018] The inner fins have an outward expansion force, which makes the outer fins easier to shape and fit. The outward expansion force of the inner fins provides an outward expansion force for the outer fins, which improves stability and makes them more comfortable to wear. The compression cavity can cushion the overall shaking and prevent the whole thing from falling off the ears.
[0019] 2. When the slider is pushed upwards, the connecting strip on the slider rotates on the turntable shaft. At this time, when the half gear on the connecting strip rotates, it drives the gear to rotate. The gear then drives the take-up wheel to rotate through the turntable, winding the protective sleeve. This allows the length of the exposed data cable to be adjusted, making it more comfortable for the user to wear. Attached Figure Description

[0026] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0027] Reference Figures 1 to 6 The bone conduction hearing aid shown includes a receiver 1, a silicone wire sleeve 2 connected to one side of the receiver 1, a data cable connected to the receiver 1 disposed inside the silicone wire sleeve 2, and an earplug connected to the data cable, and further includes:
[0028] The fin limiting mechanism is detachably connected to the receiver 1 and partially encloses the receiver 1. The outer surface of the fin limiting mechanism is provided with an inwardly concave arc-shaped surface. The fin limiting mechanism includes an inner fin 6 and an outer fin 7. The inner fin 6 and the outer fin 7 are formed as one piece in the middle, and a compression cavity 6-7 is provided between the inner fin 6 and the outer fin 7.
[0029] It should be noted that the inner fin 6 and the outer fin 7 are integrally formed in the middle, so that the formed part is fixed to the receiver 1. The installation method is a snap-fit method. The receiver 1 is provided with a slot and the formed part is provided with a lever, so that it can be removed at any time when adjustment is needed.
[0030] The inner fin 6 and the outer fin 7 are wing-shaped and move upward from the receiver 1 to clamp and wrap around the receiver. The advantage of this design is that the inwardly concave arc surface of the outer fin 7 can fit snugly against the ear, which improves the stability of wearing it. Furthermore, the outer fin 7 can be easily removed by pressing it in opposite directions.
[0031] Further understanding reveals that the inner fin 6 has an outward expansion force, and the outer fin 7 is better shaped and easier to fit. The outward expansion force of the inner fin 6 provides an outward expansion force for the outer fin 7, which improves stability and makes wearing more comfortable. The compression chambers 6-7 can buffer the overall shaking and prevent the whole thing from falling off the ears.
[0032] A cable management mechanism 10 is located at the tail of the receiver 1, with a portion of the cable management mechanism 10 protruding from the tail of the receiver 1. The cable management mechanism 10 includes a circular take-up compartment 101, within which a take-up reel is installed. The end of the data cable is wound around the take-up reel. The cable management mechanism 10 also includes a damping surface 103, which is located on the inner wall of the circular take-up compartment 101. An arc-shaped slide rail 104 is installed on the circular take-up compartment 101, and a sliding piece 102 is slidably connected to the arc-shaped slide rail 104. A turntable 106 is rotatably connected to the inner wall of the circular take-up compartment 101. The take-up reel is fixedly connected to the turntable 106. A connecting strip is fixedly connected to the sliding piece 102, passing through the circular take-up compartment 101 and rotating on the axis of the turntable 106. A gear 105 is fixedly connected to the turntable 106, and a half-gear 107 is fixedly connected to the connecting strip.
[0033] The data cable includes a protective sleeve 3 and a cable 9 disposed inside the protective sleeve 3. The cable 9 is connected to internal components, and one end of the protective sleeve 3 is fitted onto a take-up reel.
[0034] When using the data cable, the protective sleeve 3 of the data cable is malleable, which helps to keep the receiver 1 and the earbud stable during wear. When the slider 102 is moved upward, the connecting strip on the slider 102 rotates on the axis of the turntable 106. At this time, the half gear 107 on the connecting strip rotates, which drives the gear 105 to rotate. The gear 105 then drives the take-up wheel to rotate through the turntable 106, winding the protective sleeve 3. This allows the length of the exposed data cable to be adjusted, making it more comfortable for the user to wear.
[0035] The earplug includes a mushroom-shaped cap 4, inside which is a plug body 5. The cap 4 and the plug body 5 are integrally formed. The cap 4 has multiple deformation holes, and the head of the cap 4 has a sound channel hole 8, which makes it easy to place the earplug outside the two holes. When the pressure in the ear canal is reduced, it can also play a better role in bone conduction.
[0036] The silicone wire sleeve 2 includes a connecting root 2-1, which is snapped into a slot provided on the outer shell of the receiver 1.
[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
