Description

Technical Field

[0001] The present invention relates to the technical field of bone conduction hearing aids, and in particular to a bone conduction hearing aid with snap-on magnetic connection and a control method and system thereof. Background Art

[0002] Bone conduction is a method of sound conduction, which converts sound into mechanical vibrations of different frequencies, and transmits sound waves through the human skull, bony labyrinth, inner ear lymph, spiral organ, auditory nerve, and auditory center. Compared with the classic sound conduction method of generating sound waves through the diaphragm, bone conduction eliminates many steps of sound wave transmission and can achieve clear sound restoration in noisy environments. Bone conduction technology is divided into bone conduction speaker technology and bone conduction microphone technology. Bone conduction speaker technology is used for receiving calls, which means listening to sounds. Air conduction speakers convert electrical signals into sound waves and transmit them to the auditory nerve.

[0003] In the prior art, both bone conduction earphones and hearing aids use a head-mounted structure, and their basic structure includes a vibrator and a headband, which is fixed to the back of the head with the headband, and then the vibrator is attached to the skin below the temple to achieve vibration sound transmission; however, among many users who need bone conduction hearing aids, it is not that both ears have lost their hearing function, but that one ear still retains the hearing function, and the other ear needs to rely on the bone conduction hearing aid; and in the use of bone conduction hearing aids, it depends on the vibration transmission of the bone conduction hearing aid to the specific missing frequency band. If the hearing function is not lost, the bone conduction hearing aid will not be used. If the hearing aid is worn on the ear for a long time, two sounds will be heard, which will inevitably cause interference to the customer. In order to solve this problem, there is a method in the prior art that directly prepares a unilaterally worn bone conduction hearing aid, but the unilaterally worn bone conduction hearing aid cannot be clamped tightly on the skin and is not suitable for a bone conduction hearing aid that utilizes vibration conduction. It can be seen that for users with different degrees of hearing loss in both ears, the existing headband-type bone conduction hearing aids and unilateral bone conduction hearing aids are not suitable. Therefore, a bone conduction hearing aid that can be suitable for the left and right ears with different needs is needed. Summary of the invention

[0037] In order to more clearly illustrate the present invention, the present invention is further described below in conjunction with the accompanying drawings.

[0038] In the following description, general election example details are given to provide a deeper understanding of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all embodiments. It should be understood that the specific embodiments are only used to explain the present invention and are not used to limit the present invention.

[0039] It should be understood that when the terms "include" and / or "comprises" are used in this specification, they indicate the existence of the stated features, integers, steps, operations, elements or components, but do not exclude the existence or addition of one or more other features, integers, steps, operations, elements, components or combinations thereof.

[0040] In the prior art, bone conduction hearing aids are different from sound-transmitting headphones. They use vibration to transmit sound, so they need to fit closely to the skin. Therefore, the use of unilateral hearing aids has been ignored in the prior art, which has led to the inability of users with hearing impairments in the left and right ears to use headband-type bone conduction hearing aids for assistance; therefore, the inventor discovered in the exploration that the use of a spliced ​​structure can form a differentiated bone conduction effect; and the simple use of a spliced ​​structure cannot achieve an excellent bone conduction vibration effect. One reason is that the bone conduction hearing aid needs to convert the sound signal for gain compensation and then output a vibration signal, so the control system needs to control the data. To process, and the structure of the bone conduction hearing aid is compact, so where should the control system be designed, and how to achieve the differentiated output at the left and right ends, whether two control systems are needed, are all issues that affect and restrain each other; secondly, this function requires the installation of the pickup part on the bone conduction hearing aid due to the modification of the structure of the original external pickup box, so it is easy to produce the problem of howling, which is another difficulty; thirdly, the product is aimed at the general public, and it can provide headphones with differentiated bone conduction effects, but it also needs to be able to provide the same bone conduction vibration output function, so how to coordinate between the two is also not disclosed in the prior art. In the prior art, the document with application number 201610703288.8 discloses a telescopic, foldable and portable bone conduction receiver; it realizes structural detachability through a telescopic and foldable structure; but it cannot solve the technical problems mentioned in the above application. Based on this, the present application provides a solution, first focusing on solving the problem of independent bone conduction vibration on both sides and forming a compact structure to wear; and further addressing the problem of howling caused by the pickup being placed on the curved part.

[0041] The present invention provides a bone conduction hearing aid with snap-on magnetic connection, please refer to Figure 1-Figure 6 ;include,

[0042] A first bending portion 1, one end of which is connected to a first vibrator 2, and the other end of which is connected to a first combining portion 3;

[0043] A second bending portion 4, one end of which is connected to a second vibrator 5, and the other end of which is connected to a second combining portion 6;

[0044] The first vibrator 2 and the second vibrator 5 are used to fit the skin to perform bone conduction vibration and sound transmission; the first combination part 3 and the second combination part 6 are snap-connected, that is, the first bending part 1 and the second bending part 4 are fixed as a whole by the snap-connected structure of the first combination part and the second combination part; and when the snap-connected connection forms a headband structure, the first combination part and the second combination part are configured to be in electrical contact or non-electrical contact. The so-called headband structure is a common head-mounted bone conduction hearing aid form in the prior art, which can achieve close fit with the user's skin through the elastic force of the two curved parts; in this solution, the first combination part and the second combination part are buckled together to first achieve structural stability; and further utilize the solution that can be selected in the electrical contact state and the non-electrical contact state after buckling; first, the non-electrical contact state means that the first combination part and the second combination part are only structurally fixed, but there is no electrical connection and information interaction, and the first combination part can control the first vibrator to output the bone conduction vibration signal, and the second combination part can control the second vibrator to output the bone conduction vibration signal, so the first vibrator and the second vibrator can achieve independent output and processing functions, first realize differentiated processing, and meet the requirements of bone conduction hearing aids in structure, and can fit closely to the user's skin. At the same time, when one side is not in use, a model with a fixing function can also be worn to form a complete headband for wearing and use.

[0045] In this embodiment, the first bending part 1 is a flexible part, which can provide the function of bending and shaping; the electrical connection line of the first combination part 3 is connected to the first vibrator from the cavity of the first bending part 1; since the first combination part needs to be structurally fixed, a rigid structure is adopted, which will not be convenient to be directly placed in the flexible first bending part; the first combination part 3 is located on the side of the first bending part away from the vibrator. More specifically, the first combination part is located on the side away from the enclosed area of ​​the headband structure. First, the distance between the vibrator and the first combination part can be increased to reduce howling; second, the structural fixation of the first combination part and the second combination part will not affect the bending adjustment of the first bending part and the second bending part.

[0046] In this embodiment, the second bending part is a flexible member, the electrical connection line of the second combination part is connected to the second vibrator from the cavity of the second bending part; the second combination part is located on the side of the second bending part away from the vibrator. The second bending part has a similar structure to the first bending part.

[0047] In this embodiment, the first combination part 3 includes a first shell 31; the first shell 31 is provided with an electrically connected first control board 32, a first pickup 33 and a first battery 34; the first control board 32 is electrically connected to the first vibrator 2; the first shell 31 is provided with a first pickup hole 311 at one end away from the second combination part 6, and the first pickup 33 is provided in the first pickup hole 311; the first shell 31 is provided with a groove 312 on the side close to the second combination part 6, and the bottom surface of the groove 312 is provided with a first magnetic electrode probe 313; the first magnetic electrode probe 313 is electrically connected to the first control board; when the first combination part and the second combination part are configured to be in electrical contact, the first magnetic electrode probe is electrically connected to the second combination part. In terms of structure, the groove is used for buckling, so after the structure is stably connected, the first magnetic electrode probe located in the groove can be more stably electrically connected to the second combination part.

[0048] As a corresponding solution, the second combination part 6 includes a second shell 61; the second shell 61 is provided with an electrically connected second control board 62, a second pickup 63 and a second battery 64; the second control board 62 is electrically connected to the second vibrator 5; the second shell 61 is provided with a second pickup hole 611 at one end away from the second combination part 6, and the second pickup hole is provided with a second pickup; the second shell is provided with a protrusion 612 on the side close to the second combination part, the protrusion is adapted to the groove, and a second magnetic electrode sheet 613 is embedded in the protrusion; the second magnetic electrode sheet is electrically connected to the second control board; when the first combination part and the second combination part are configured to be in electrical contact, the first magnetic electrode probe is electrically connected to the second magnetic electrode sheet. Through the electrically connected state, the effect of integrated output can be achieved; and the whistling problem of the integrated bone conduction hearing aid can be solved in terms of structure.

[0049] In this embodiment, the first shell 31 is also provided with a push plate 35 and an insulating member connected to each other, a part of the insulating member extends into the groove, and the push plate is used to push the insulating member into the groove; when the insulating member is located between the first magnetic electrode probe and the second magnetic electrode sheet, the first combination part and the second combination part are in a non-electrical contact state. The so-called insulating member can be a plastic sheet, which can allow the customer to control whether the insulating member plays an insulating role by pushing and pulling the push plate, and its volume does not need to be very large, because the number of electrode probes is at most two electrical signal terminals and one signal output terminal, so the contact area is small, and the plastic sheet or silicone sheet has a certain elasticity, which can be completely electrically isolated.

[0050] In this embodiment, a buckle is provided at one end of the first shell 31 and the second shell 61 that is close to each other to fix the first shell and the second shell. The buckle shape is not limited here, and serves as a reinforcement structure for connection stability.

[0051] In this embodiment, the first shell 31 partially fits the first curved portion 1, and the portion of the first shell 31 spaced apart from the first curved portion bends toward the side close to the first vibrator to form a first arc angle 314, and the first sound pickup hole is arranged on the first arc angle; the second shell 61 partially fits the second curved portion, and the portion of the second shell spaced apart from the second curved portion bends toward the side close to the second vibrator to form a second arc angle 614, and the second sound pickup hole is arranged on the second arc angle. The reason for the howling is that the distance between the sound pickup area and the vibrator is too close, and the second reason is that the sound pickup is located in an area with a complex electromagnetic environment; therefore, the first arc angle can be away from the first vibrator while being away from the possible electromagnetic complex area where the first combination part and the second combination part are combined; and its sound pickup range can be wider through the arc design, and it is not arranged inside the curved portion, which can better reduce the howling. And when used in electrical contact, the sound pickup effect can be enhanced.

[0052] Also included is a bone conduction hearing aid control method, see Figure 7 ; Applied to the above-mentioned bone conduction hearing aid; the method comprises the following steps:

[0053] The first combination unit acquires an external sound signal, and the first control board generates a first vibration signal according to a first gain function;

[0054] The second combination unit obtains an external sound signal, and the second control board generates a second vibration signal according to a second gain function; the so-called first gain function and the second gain function can have multiple groups; and can be different, which are obtained by adjusting when the product is purchased, and are a prerequisite for the use of the bone conduction hearing aid;

[0055] When the first assembly part and the second assembly part are configured to be in electrical contact, the first vibration signal is transmitted to the first vibrator and the second vibrator for bone conduction output, and the second control board enters a dormant state; that is, when in electrical contact, the battery can be shared to improve battery life, and the same signal can be output. Therefore, under the premise of only needing to output the same vibration signal, only one control board is needed for data fitting to achieve the output effect;

[0056] When the first combination part and the second combination part are configured in a non-electrical contact state, the first vibration signal is transmitted to the first vibrator for bone conduction output, and the second vibration signal is transmitted to the second vibrator for bone conduction output.

[0057] Also included is a bone conduction hearing aid system and a hearing aid control method.

[0058] The advantages of the present invention are:

[0059] The first bending portion and the second bending portion firstly utilize the first combination portion and the second combination portion respectively to achieve the effect of unilateral bone conduction vibration, and then further utilize the characteristic that the first combination portion and the second combination portion can be structurally spliced ​​to combine into a headband-type bone conduction hearing aid, and there is also an electrical connection structure in the combined structure, which can achieve data exchange and transmission, and facilitate adaptive adjustment for users with differentiated deafness in the left and right ears.

[0060] The above disclosures are only several specific embodiments of the present invention, but the present invention is not limited thereto, and any changes that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
