Description

Technical Field

[0001] This utility model relates to the technical field of audio vibration devices, specifically to an audio vibration device that prevents wire breakage. Background Technology

[0002] In the field of audio equipment, audio vibration devices are key components for the generation and propagation of sound. Traditional audio vibration devices typically consist of a base, a top cover, a magnet, a coil, a coil frame, and a vibrating component. Their working principle is based on the interaction between the magnet and the coil. When current flows through the coil, the magnetic field causes the coil to move, which in turn drives the connected vibrating component to vibrate, ultimately producing sound output.

[0003] However, in practical applications, traditional audio vibration devices have a significant problem. Because audio vibration devices generate continuous vibration during operation, the connection between the power cord and the coil is often subjected to stress due to this frequent vibration. Over time and with an increase in the number of vibrations, the connection between the power cord and the coil is prone to loosening or even breaking, causing the audio equipment to malfunction and severely affecting its performance and lifespan.

[0004] Chinese invention patent CN101931843A discloses an audio vibration device. The device includes a support frame, a magnetic field generator, a vibrating plate, a vibration bracket, a coil frame, and a coil. The coil frame is located in the magnetic field generated by the magnetic field generator, and a coil is disposed on it. The vibrating plate is connected to the support frame and is engaged with the coil frame. The vibration bracket is connected to the vibrating plate and is used to drive an external vibration medium to vibrate. However, in the operation of this audio vibration device, high-frequency vibration can easily cause problems such as the power lead of the coil to break and the power wire to disconnect.

[0005] Therefore, developing an audio vibration device that can effectively prevent the power cord and coil from disconnecting during vibration has become a crucial problem urgently needing to be solved in the field of audio equipment technology. This invention addresses this technical challenge by proposing an anti-disconnection audio vibration device that achieves a stable and reliable electrical connection between the power cord and the coil, providing strong support for the high performance and long lifespan of audio equipment. Utility Model Content

[0006] The present invention aims to solve the problem that the power cord and coil in traditional audio vibration devices are easily disconnected during vibration, which affects the performance and service life of the audio equipment.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An anti-breakage audio vibration device includes a stator assembly, a mover assembly, and an elastic leaf spring that elastically supports the mover assembly on the stator assembly. The mover assembly includes a mover coil and a coil support, and the coil support is fixed on the elastic leaf spring. The elastic leaf spring has an elastic part suitable for fixing the mover assembly and a fixing part suitable for fixing the stator assembly. The power supply lead of the mover coil is electrically connected to the elastic part, and the fixing part is electrically connected to a power supply part. The elastic leaf spring is configured to provide elastic support for the reciprocating motion assembly while establishing an electrical connection between the motion coil and the power supply unit to prevent the power lead of the motion coil from disconnecting during the vibration of the motion assembly.

[0008] Furthermore, the elastic part includes a positioning piece and an elastic arm, the elastic arm being connected between the positioning piece and the fixing part.

[0009] Furthermore, the mover assembly is fixed to the positioning plate, and the power lead of the mover coil is fixed to the positioning plate.

[0011] Furthermore, the positioning piece is provided with at least one lead fixing hole, and the power lead of the moving coil is embedded and fixed in the lead fixing hole.

[0012] Furthermore, the coil support is provided with a lead-out groove to allow the power lead of the moving coil to be fixed to the positioning plate through the lead-out groove.

[0013] Furthermore, the fixing part includes a connecting hole and a power connection hole, the connecting hole being configured to be fixedly connected to the stator assembly, and the power connection hole being configured to be electrically connected to the power supply part via a power wire.

[0014] Furthermore, the power connection hole is located at the end of the connection hole away from the elastic arm to prevent the power wire from breaking during the vibration of the moving part assembly.

[0015] Furthermore, the stator assembly is provided with a connecting part that is fixedly connected to the fixing part, and the connecting part is provided with a threaded hole suitable for threaded connection, and the threaded hole and the connecting hole are arranged on the same axis.

[0016] Furthermore, the elastic leaf springs are configured as two symmetrical about the coil support axis to facilitate fixing the elastic leaf springs to the mover assembly.

[0017] The above technical solution achieves the following technical effects: This invention utilizes a unique design of an elastic leaf spring to provide elastic support for the moving part assembly while establishing a stable electrical connection between the moving part coil and the power supply unit.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the utility model will be further described in detail below with reference to the accompanying drawings. The components of the embodiments of this utility model described and shown in the accompanying drawings can be arranged and designed in various different configurations. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0028] Example 1: Please refer to Figures 1-7 This embodiment details the specific structure of an anti-breakage audio vibration device. The anti-breakage audio vibration device mainly consists of a stator assembly 1, a mover assembly 2, and an elastic leaf spring 3. These components work together to achieve audio vibration while effectively preventing the power lead 211 of the mover coil 21 from breaking during vibration.

[0029] The stator assembly 1, serving as the fixed part 31 of the entire device, provides a stable magnetic field environment for the vibration of the mover assembly 2. In this embodiment, the stator assembly 1 includes a base and a magnetic body disposed on the base. The base is made of a high-strength, low-magnetic-loss material, ensuring its mechanical strength and stability while reducing interference with the magnetic field. The magnetic body is made of high-performance neodymium iron boron permanent magnet material, which can generate a strong magnetic field within a small volume, providing sufficient power for the vibration of the mover assembly 2. The magnetic body is firmly fixed to the base, ensuring that it will not shift or loosen during operation. The stator assembly 1 is also equipped with a connecting part 11 suitable for fixing to the fixed part 31 of the elastic leaf spring 3. The connecting part 11 is aligned with the connecting hole 311 of the fixed part 31 on the elastic leaf spring 3. The connecting part 11 is equipped with a threaded hole for threaded connection. The threaded hole is machined with precision according to national standards to ensure accurate matching with the connecting hole 311 of the fixed part 31 on the elastic leaf spring 3, achieving a stable threaded connection.

[0030] The mover assembly 2 includes a mover coil 21 and a coil support 22, with the coil support 22 fixed to the elastic leaf spring 3. The coil support 22 is made of a lightweight, high-strength non-metallic material, such as polyimide (PI), which has excellent high-temperature resistance, chemical corrosion resistance, and mechanical properties. It maintains a stable shape during vibration while reducing the overall weight of the mover assembly 2 and improving vibration efficiency. The mover coil 21 is the key component for generating vibration. When current passes through the mover coil 21, the mover assembly 2 is subjected to a force under the influence of the magnetic field, resulting in reciprocating vibration.

[0031] To achieve electrical connection between the power lead 211 of the moving coil 21 and the elastic leaf spring 3, a lead-out groove 221 is provided on the coil support 22. The width and depth of the lead-out groove 221 are rationally designed according to the diameter of the power lead 211 to ensure that the power lead 211 can smoothly pass through the lead-out groove 221 and connect with the elastic part 32 of the elastic leaf spring 3. The moving coil 21 is made of high-conductivity copper wire, and the diameter of the copper wire is selected according to the power and current requirements of the device. During the winding process, precision winding equipment is used to ensure accurate number of turns and neat arrangement of the coil, so as to improve the inductance and resistance stability of the coil and thus ensure the vibration performance of the device.

[0032] The coil support 22 has a circular groove between its upper and lower ends, which is suitable for winding the moving coil 21, so as to stably wind the moving coil 21 onto the coil support 22 and prevent the moving coil 21 from separating from the coil support 22. The top of the coil support 22 is provided with one or more heat dissipation holes to dissipate the heat generated when vibration occurs and to reduce the noise generated when vibration occurs.

[0033] The elastic leaf spring 3 is the core component of this invention. It has an elastic part 32 and a fixing part 31, and is arranged symmetrically about the axis of the coil support 22. The two elastic leaf springs 3 are installed at a certain distance from each other and are made of the same material. This symmetrical design facilitates the secure and accurate fixing of the elastic leaf springs 3 to the mover assembly 2. The two elastic leaf springs 3 are electrically connected to the power lead 211 of the mover coil 21.

[0034] The elastic part 32 includes a positioning plate 321 and an elastic arm 322, with the elastic arm 322 connecting the positioning plate 321 and the fixing part 31. The moving part assembly 2 is fixed to the positioning plate 321, specifically through bolt connection or other means. The power lead 211 of the moving part coil 21 is fixed to the positioning plate 321, so that the power lead 211 of the moving part coil 21 vibrates synchronously with the moving part assembly 2 and the elastic leaf spring 3, preventing the power lead 211 of the moving part coil 21 from breaking during the vibration of the moving part assembly. The positioning plate 321 is provided with at least one lead fixing hole, in which the power lead 211 of the moving part coil 21 is embedded and fixed, for example, by welding, to ensure a firm connection between the power lead 211 and the positioning plate 321, preventing loosening during vibration. In addition, the coil support 22 is provided with a wire outlet groove 221. The power lead 211 of the moving coil 21 is guided through the wire outlet groove 221 and fixed to the lead fixing hole on the positioning piece 321. The design of the wire outlet groove 221 makes the power lead 211 more regular and reduces the friction and interference between the lead and other components during vibration.

[0035] The elastic arm 322 is configured to form a radially elongated, curved strip shape at the edge of the elastic leaf spring 3, and at least one such arm is provided. This shape design allows the elastic arm 322 to have a certain degree of elasticity, providing sufficient elastic support for the reciprocating vibration of the mover assembly 2, while also accommodating the deformation of the mover assembly 2 during vibration, ensuring the stable operation of the device.

[0036] The fixing part 31 includes a connecting hole 311 and a power connection hole 312. The connecting hole 311 is located at the end of the elastic arm 322 and is used to fix it to the connecting part 11 of the stator assembly 1 using a threaded fastener such as a bolt. The threaded hole of the connecting part 11 of the stator assembly 1 and the connecting hole 311 are arranged on the same axis to ensure the accuracy and stability of the connection. The power connection hole 312 is located at the end of the connecting hole 311 away from the elastic arm 322. The fixing part 31 is electrically connected to the power supply part through the power connection hole 312 via a power wire 4. By placing the power connection hole 312 in this position, the power wire 4 can be prevented from breaking due to excessive stress during the vibration of the rotor assembly 2, thus ensuring the stability of the electrical connection.

[0037] Please refer to Figures 1-7When the audio vibration device starts working, the power supply unit supplies power to the moving coil 21 through the power wire 4. When the current passes through the moving coil 21, under the action of the magnetic field generated by the stator assembly 1, the moving coil 21 is subjected to a force that drives the moving assembly 2 to reciprocate. During this process, the elastic arm 322 of the elastic leaf spring 3 undergoes elastic deformation, providing elastic support for the moving assembly 2, enabling it to vibrate stably within a certain range. At the same time, since the power lead 211 of the moving coil 21 is firmly connected to the elastic leaf spring 3 through the lead fixing hole on the positioning piece 321, and the fixing part 31 of the elastic leaf spring 3 maintains a stable electrical connection with the power supply unit through a reasonable structural design, the problem of the power line and coil connection loosening and disconnecting due to frequent vibration in traditional audio vibration devices is effectively avoided. This ensures that the audio equipment can maintain a stable and reliable electrical connection even under long-term high-frequency vibration working environment, guaranteeing the normal operation of the equipment.

[0038] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
