Description

Technical Field

[0001] The present invention relates to the field of bone conduction technology, and in particular to a broadband integrated bone conduction speaker device. Background Art

[0002] Bone conduction is a method of sound conduction that bypasses the outer ear and middle ear and transmits sound directly to the inner ear through the bones. The broadband integrated bone conduction speaker converts electrical signals into mechanical vibrations through the collaborative work of vibration components and magnetic circuit components. These vibrations are transmitted directly to the skull through the vibration shell, and then through the bony labyrinth, the spiral organ, the inner ear lymph and the auditory center, and are finally perceived by the human ear as sound. Unlike traditional air conduction speakers, bone conduction speakers bypass the outer ear and middle ear and transmit sound directly through the bones, so they have better noise reduction and wearing comfort. By transmitting sound directly through the bones, the broadband integrated bone conduction speaker can reduce the attenuation and distortion of sound in the air, thereby providing clearer and more realistic sound quality.

[0003] In actual use, existing broadband integrated bone conduction speaker devices create gaps when the shell is attached to the skin surface, as the skin surface is not flat. This affects sound transmission and makes adaptive fit difficult to reduce gaps. Therefore, a new technical solution is needed to address this issue. Summary of the Invention

[0004] The purpose of the present invention is to provide a broadband integrated bone conduction speaker device to solve the problems raised in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a broadband integrated bone conduction speaker device, comprising an elastic handle, both ends of the elastic handle being fixedly connected to a housing, an outer end of the housing being fixedly connected to a bonding plate, an inner cavity of the housing being fixed to a magnetic element, an outer end surface of the magnetic element being fixed to a washer, an inner wall of the housing being fixedly mounted to a coil, and a vibration plate being provided on the other side of the inner cavity of the housing;

[0006] The outer end surface of the bonding plate is provided with a mounting groove, the inner cavity of the mounting groove is provided with a plurality of evenly distributed bonding blocks, the inner end surface of the bonding block is provided with a slot, the inner cavity of the slot is plugged with an insert block, the insert block is fixedly connected to the inner wall of the mounting groove, the other end of the insert block is fixed with a first spring, and the outer end of the first spring is fixedly connected to the inner wall of the slot.

[0007] By adopting the above technical solution, first, the elastic handle has a certain elasticity of opening and retracting inward, so that the elastic handle is pulled open so that the shells on both sides are aligned with the fitting part of the head, so that the fitting plate can fit the skin surface, and then through the coordinated work of the magnetic element, the vibration plate and the coil, the electrical signal is converted into mechanical vibration, which is transmitted through the vibration plate and transmitted to the fitting block, thereby directly transmitting it to the skull. In the fitting process, the fitting block embedded in the surface of the fitting plate will first fit the user's skin, and for uneven skin, the fitting block will compress the first spring, thereby adaptively adjusting the fit between each fitting block and the skin, which is beneficial to improving the overall fit, thereby helping to reduce gaps, and thereby helping to improve the bone conduction sound quality.

[0009] By adopting the above technical solution, in actual use, the elastic sheet can be deformed by rotating the adjusting bolt under the action of threaded drive, so that the two ends of the elastic sheet will generate thrust on both sides of the outer wall of the elastic handle, so that the elastic handle will continue to clamp inward, which is beneficial to improve the fit between the shell and the fitting plate and the patient's skin, and then it is beneficial to further improve the fitting effect and improve adaptability.

In addition, the setting of the tapered hole can further increase the contact effect with the inner wall of the through hole when the energy impacts in the through hole, thereby further improving the vibration effect.

[0017] As a preferred embodiment of the present invention, a plurality of the bonding blocks are bonded to each other.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] The present invention is such that when the two side shells are attached to the user's skin surface, the movable blocks embedded on the surface of the attachment plate will first attach to the user's skin. In addition, for uneven skin, the attachment blocks will compress the first spring, thereby adaptively adjusting the fit between each attachment block and the skin, thereby improving the overall fit, reducing gaps, and improving the quality of bone conduction sound.

[0037] See also Figure 1-5 The present invention provides a technical solution: a broadband integrated bone conduction speaker device, comprising an elastic handle 2, a sponge pad fixed to the inner wall of the elastic handle 2, a shell 1 fixedly connected to both ends of the elastic handle 2, a bonding plate 3 fixedly connected to the outer end of the shell 1, a magnetic element 16 fixed to the inner cavity of the shell 1, a washer 12 fixed to the outer end surface of the magnetic element 16, a coil 13 fixedly mounted on the inner wall of the shell 1, and a vibrating plate 15 provided on the other side of the inner cavity of the shell 1;

[0039] It should be understood that in actual use, first, the elastic handle 2 has a certain elasticity of opening and retracting inward, so that the elastic handle 2 is pulled open so that the shells 1 on both sides are aligned with the fitting part of the head, so that the fitting plate 3 can fit the skin surface, and then through the coordinated work of the magnetic element 16, the vibration plate 15 and the coil 13, the electrical signal is converted into mechanical vibration. These vibrations are transmitted through the vibration plate 15 and transmitted to the fitting block 31, so as to be directly transmitted to the skull. In the fitting process, the fitting block 31 embedded in the surface of the fitting plate 3 will first fit the user's skin, and for uneven skin, the fitting block 31 will compress the first spring 33, thereby adaptively adjusting the fit between each fitting block 31 and the skin, which is beneficial to improving the overall fit, thereby helping to reduce gaps, and thereby helping to improve the bone conduction sound quality.
