Description

Technical Field

[0001] The utility model relates to the technical field of sound listening devices, and particularly relates to a bone conduction speaker structure. Background Art

[0002] For the speaker structure used in bone conduction hearing aid earphones or bone conduction hearing aids, the common installation method of the oscillator is to directly use glue to stick it on the silicone skin. When worn, the silicone skin fits near the ear, and the sound is generated by the vibration of the oscillator and transmitted into the auditory system through bone conduction. Different from ordinary earphones that mainly transmit mid-low frequency sounds, hearing aid earphones or hearing aids need to transmit mid-high frequency sounds, and the use of glue will affect the transmission of mid-high frequency sounds. If too much glue is used to adhere the oscillator, it may cause the mid-high frequency sounds to disappear. However, if less glue is used for adhesion, it is also easy to fall off. Moreover, for the howling suppression and DRSP of bone conduction hearing aids, since there are algorithms in them, the oscillator needs to be firmly connected to the silicone sheet to ensure consistency and stability.

[0029] In order to make the objectives, technical solutions and advantages of the present utility model more clear and understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0030] As Figures 1 to 9 shown, a bone conduction speaker structure of the present utility model is installed on a bone conduction hearing aid device 1, and includes an oscillator 2, a conduction member 3, and a rubber pad 4. The oscillator 2 is suspended and connected to the rubber pad 4 through the conduction member 3. The conduction member 3 includes a conduction bottom cover 5 and a conduction boss 6. The conduction boss 6 is connected above the conduction bottom cover 5. An oscillator slot 31 is provided in the conduction member 3. The oscillator 2 is connected to the conduction bottom cover 5 and the top of the oscillator 2 is located in the oscillator slot 31. The conduction boss 6 is connected to the rubber pad 4, and the periphery of the rubber pad 4 is connected to the bone conduction hearing aid device 1.

[0031] This structure can be used for the assembly and application of bone conduction speakers in bone conduction hearing aids such as bone conduction headphones, bone conduction hearing aids, and bone conduction assisted listening headphones 1. The structure of the conduction component 3 is used to connect between the oscillator 2 and the rubber pad 4, avoiding the problem that the excessive glue used in the original direct connection of the oscillator 2 and the rubber pad 4 affects sound conduction. In the conduction component 3, the conduction bottom cover 5 serves as the connection part of the oscillator 2, and the conduction boss 6 serves as the connection part of the rubber pad 4. The vibration of the oscillator 2 is transmitted to the conduction bottom cover 5 and then transmitted to the human auditory system through the synchronous vibration of the conduction boss 6. The oscillator 2 is suspended above the rubber pad 4 through the conduction component 3, which can ensure that the oscillator 2 has sufficient vibration space and is also conducive to the full transmission of the vibration of the oscillator 2 to the conduction component 3 and the rubber pad 4.

[0032] There is a gap between the conduction bottom cover 5 and the rubber pad 4. When the sound vibration of the oscillator 2 is transmitted to the conduction component 3, it will cause the synchronous vibration of the conduction bottom cover 5, and the gap provides space for the vibration of the conduction bottom cover 5, so that the sound wave frequency can be better transmitted.

[0033] There is a wrap-around edge 51 around the lower part of the conduction bottom cover 5. The wrap-around edge 51, the conduction bottom cover 5, and the conduction boss 6 form an oscillator slot 31, and the oscillator 2 is snap-fitted into the wrap-around edge 51. The top of the oscillator 2 can be fixed through the wrap-around edge 51 to complete the docking of the conduction component 3 and the oscillator 2, and realize the conduction of the sound wave vibration of the oscillator 2 by the conduction component 3. The oscillator slot 31 provides space for the installation of the top of the oscillator 2, so that the top of the oscillator 2 can be fixed on the conduction component 3. The conduction component 3 is made of aluminum iron material, and the aluminum iron material is more conducive to the conduction of vibration.

[0034] The material of the rubber pad 4 is soft silicone. Soft silicone can better conduct sound waves, while hard glue is difficult to conduct sound waves. Moreover, soft silicone is also convenient for the installation of the conduction component 3, and even when the hearing aid device falls, the conduction component 3 will not fall off from the soft silicone.

[0035] There is a convex ring 41 on the periphery of the rubber pad 4, and the rubber pad 4 is connected to the bone conduction device through the convex ring 41. The convex ring 41 on the rubber pad 4 is adapted to the shell at the earpiece 11 of the bone conduction hearing aid device 1. Through the convex ring 41, the rubber pad 4 can be fixed at the earpiece 11, so as to fix the entire bone conduction structure in the bone conduction device together.

[0036] Based on the above structure, the present utility model provides the following three deformed bone conduction speaker structures.

[0037] Embodiment 1:

[0038] As Figures 2 to 5As shown in the figure, the rubber pad 4 is provided with a columnar through hole 42. The conduction boss 6 is of a columnar structure. The conduction boss 6 is adhered in the columnar through hole 42, and the top of the conduction boss 6 protrudes from the rubber pad 4. The rubber pad 4 can increase the comfort of contact with the human body during wearing, and the conduction boss 6 protruding from the rubber pad 4 can directly complete the conduction of sound waves when contacting the human body. The vibration surface of the conduction boss 6 is not covered by the rubber pad 4, which can reduce the interference of the rubber pad 4. The top of the conduction boss 6 can be flush with the rubber pad 4, or can slightly protrude from the rubber pad 4 considering the wearing comfort.

[0039] For the connection between the columnar conduction boss 6 and the columnar through hole 42 of the rubber pad 4, less glue adhesion is required. Since the contact surface between the conduction boss 6 and the columnar through hole 42 is small, the amount of glue used can also be reduced. Moreover, the glue is mainly pasted on the side of the conduction boss 6. Coupled with the fact that the conduction boss 6 is in direct contact with the human body, the influence of the glue on the sound vibration propagation can be greatly reduced. Compared with the traditional way of directly adhering the rubber pad 4 to the oscillator 2 with glue, where the glue covers the sound wave vibration propagation surface and affects the sound propagation in the medium and high frequency bands, the structure of the first embodiment can reduce the influence on the sound in the medium and high frequency bands.

[0040] Embodiment 2:

[0041] As shown in Figure 5 、 Figure 6 、 Figure 10 、 Figure 11 the figure, the rubber pad 4 is provided with a T-shaped through hole 43. The conduction boss 6 is of a T-shaped structure. The conduction boss 6 is clamped in the T-shaped through hole 43, and the top of the conduction boss 6 protrudes from the rubber pad 4. The T-shaped through hole 43 is divided into a small-diameter through hole 44 and a large-diameter through hole 45. The small-diameter through hole 44 and the large-diameter through hole 45 are connected to form a stepped through hole. The T-shaped conduction boss 6 is divided into a conduction column 61 and a conduction surface 62. The two ends of the conduction column 61 are respectively connected to the conduction surface 62 and the conduction bottom cover 5. The conduction surface 62 and the conduction column 61 form a stepped boss. The conduction column 61 is connected in the small-diameter through hole 44, and the conduction surface 62 is connected in the large-diameter through hole 45.

[0042] In this embodiment, the connection structure between the conduction boss 6 and the rubber pad 4 does not require glue adhesion. By using the fact that the conduction surface 62 just fits with the large-diameter through hole 45, and the width of the conduction surface 62 is greater than the aperture of the small-diameter through hole 44, the conduction surface 62 can be stuck outside the small-diameter through hole 44 without falling off. The conduction column 61 is used to pass through the small-diameter through hole 44 and then connect to the conduction bottom cover 5. The vibration of the oscillator 2 is transmitted to the conduction surface 62 through the conduction bottom cover 5 and the conduction column 61. The top of the conduction surface 62 can be flush with the rubber pad 4, or can slightly protrude from the rubber pad 4 considering the wearing comfort. The rubber pad 4 can increase the comfort of contact with the human body during wearing, and the conduction surface 62 protruding from the rubber pad 4 can directly complete the conduction of sound waves when contacting the human body.

[0043] Embodiment 3:

[0044] As Figures 7 to 11 shown, a T-shaped groove 46 is provided inside the rubber pad 4, the conduction boss 6 is of a T-shaped structure, and the conduction boss 6 is clamped in the T-shaped groove 46. The T-shaped groove 46 is divided into a small-diameter groove 47 and a large-diameter groove 48. The small-diameter groove 47 and the large-diameter groove 48 communicate with each other to form a stepped groove position. The conduction boss 6 of the T-shaped structure is divided into a conduction column 61 and a conduction surface 62. Two ends of the conduction column 61 are respectively connected to the conduction surface 62 and the conduction bottom cover 5. The conduction surface 62 and the conduction column 61 form a stepped boss. The conduction column 61 is connected in the small-diameter groove 47, and the conduction surface 62 is connected in the large-diameter groove 48.

[0045] In this embodiment, the connection structure between the conduction boss 6 and the rubber pad 4 does not require glue adhesion. By using the fact that the conduction surface 62 just fits with the large-diameter groove 48, and the width of the conduction surface 62 is greater than the aperture of the small-diameter groove 47, the conduction surface 62 can be stuck outside the small-diameter groove 47 without falling off. The conduction column 61 is used to pass through the small-diameter through hole 44 and then connect to the conduction bottom cover 5. The vibration of the oscillator 2 is transmitted to the conduction surface 62 through the conduction bottom cover 5 and the conduction column 61. The conduction surface 62 in this embodiment is embedded in the rubber pad 4, that is, the conduction surface 62 contacts the human body through the rubber pad 4 covering above. After the vibration of the oscillator 2 is transmitted to the conduction surface 62, it is then transmitted to the human body through the rubber pad 4. The thickness of the rubber pad 4 should be as thin as possible. While ensuring wearing comfort, the interference in the sound wave frequency band is reduced.

[0046] The bone conduction sound amplification structure of the present utility model is convenient to install, reliable, has good consistency, better conductivity, and is of great help to the implementation of the hearing aid algorithm.

[0047] The above content is a further detailed description of the present utility model in combination with specific preferred embodiments. It cannot be determined that the specific implementation of the present utility model is only limited to these descriptions. For those of ordinary skill in the technical field to which the present utility model belongs, without departing from the concept of the present utility model, several simple deductions or replacements can still be made, and all should be regarded as belonging to the protection scope of the present utility model.
