Description

Technical Field

[0001] This invention belongs to the field of bone conduction processing technology, and particularly relates to a design method, device and application of a bone conduction oscillator with a central perforation. Background Technology

[0002] Bone conduction technology, as an innovative method of auditory conduction, has been widely used in fields such as medicine, communications, and entertainment. The bone conduction transducer, as the core component of bone conduction technology, plays the role of converting sound signals into mechanical vibrations.

[0003] However, the current design of bone conduction oscillators without a central perforation has some drawbacks and needs improvement. The main problems are as follows:

[0004] Unstable installation method: The lack of a central hole in the design makes it impossible to provide a secure mounting method for the vibrator. In actual use, the vibrator may detach due to external forces, causing interruption of auditory conduction and affecting the user's auditory experience and usage effect.

[0005] Lack of ear canal ventilation: The design without a central opening cannot adequately maintain airflow in the ear canal, which may cause discomfort for users when wearing bone conduction transducers for extended periods. Furthermore, insufficient ear canal ventilation may also affect sound transmission, reducing the user's auditory experience.

[0006] To address these issues, we need to improve the existing bone conduction transducer design. One possible solution is to add a fixing hole in the center to provide a stable transducer mounting method. This ensures the transducer is less likely to fall out, maintaining stable auditory conduction. Summary of the Invention

[0007] This invention provides a design method, device, and application of a centrally perforated bone conduction oscillator to solve the problems in the prior art.

[0008] The present invention adopts the following technical solution: a design method for a centrally perforated bone conduction oscillator, comprising a bone conduction oscillator body, wherein the stiffness coefficient of the spring sheet of the bone conduction oscillator body can be described as:

[0009]

[0010] Wherein: the mass of the fixed component (internal or external component) is m1, and the mass of the unfixed component (external or internal component) is m2; the unfixed component is connected to two springs on two surfaces, assuming the spring constants of the two springs are ks1 and ks2 respectively, then the total spring constant of the unfixed component connected to the springs is k2 = ks1 + ks2, and the target resonant frequency is ω. t .

[0018] Furthermore, a magnetic component: a magnetic component is a single magnet or a combination of multiple magnets (n magnets > 1), whose overall magnetic field is equivalent to that of a single magnet.

[0019] Furthermore, internal components: internal components can be a combination of magnets and other parts, or a combination of coils and other parts; there can be one or more magnets or coils; the internal center hole can be a regular shape such as a circle or rectangle, or other irregular shapes; it can be a through hole or a combination of multiple holes.

[0020] Furthermore, a leaf spring is a type of leaf spring with a central hole, which utilizes the deformation of an elastic sheet material to generate spring properties. The edge of the central hole and the outer edge of the leaf spring can be on the same plane, forming a planar sheet, or they can be not on the same plane, forming a cone shape or other three-dimensional shapes.

[0021] Furthermore, the outer edge or middle of the peripheral components and leaf springs are fixed, while the middle or center hole edge of the internal components and leaf springs are fixed.

This equivalent magnet (magnet 1|magnet 2|magnet 3) is then connected in series with permanent magnets 4 and 5 to form an equivalent magnet (magnet 4-(magnet 1|magnet 2|magnet 3)-magnet 5). The magnetic fields generated by the equivalent magnet (magnet 1|magnet 2|magnet 3), permanent magnet 4, and permanent magnet 5 are all oriented towards the Y+ axis, hence their directions are the same.

The magnetic field direction of permanent magnet 1 is towards the Y+ axis, and the magnetic field direction of permanent magnet 2 is towards the Y- axis. However, because the magnetic field strength of permanent magnet 2 is less than that of permanent magnet 1, the combination of permanent magnet 1 and permanent magnet 2, from the perspective of the overall external magnetic field direction, can still be considered similar to (indicated by the "=" sign in the figure) to a single magnet on the right.
