Description

Technical Field

[0001] This application relates to the technical field of music players, and in particular to a shock-absorbing ring adapted to vacuum tubes of different diameters. Background Technology

[0002] HiFi audio systems demand very high sound quality, especially in terms of timbre, which is much higher than that of ordinary audio systems. Vacuum tubes are characterized by rich overtones and a warm, mellow sound, and their timbre is widely favored by audiophiles. Therefore, vacuum tubes are an important feature of HiFi audio systems and are widely used in them.

[0003] During audio equipment use, the speaker cabinet vibrates, and these vibrations are transmitted to the internal electrodes of the vacuum tube, causing instability in the electrical signal and producing audible noise in the speaker cabinet, which is known as the "microphone effect." Currently, some manufacturers have produced shock-absorbing rings to be fitted onto vacuum tubes to reduce the vibrations they experience, thereby reducing the "microphone effect." However, vacuum tubes come in various diameters, and a single type of shock-absorbing ring cannot be adapted to various vacuum tubes of different diameters.

[0004] Therefore, this application proposes a shock-absorbing ring that is compatible with electron tubes of different diameters, and can be adapted to a variety of electron tubes of different diameters. Utility Model Content

[0005] This application provides a shock-absorbing ring adapted to electron tubes of different diameters, employing the following technical solution: A shock-absorbing ring adapted to electron tubes of different diameters includes a base with two through ends, and the inner sidewall of the base is provided with a plurality of slot groups, which are evenly spaced along the inner sidewall of the base. The slot group includes multiple slots, each slot being a groove opened on the inner wall of the substrate, and the slots are arranged along the height direction of the inner wall of the substrate; the multiple slots in the slot group are evenly spaced along the inner wall of the substrate; the slots in all the slot groups that are equidistant from the center of the substrate constitute an installation group, and the slots in each installation group are arranged to form a circle with the center of the substrate as the center; the slots in all the slot groups that are equidistant from the center of the substrate together constitute multiple installation groups, and the diameters of the circles formed by the slots in the multiple installation groups are different; It also includes a shock-absorbing pad, which is detachably installed in the slot. The shock-absorbing pad protrudes from the slot and abuts against the outer wall of the electron tube. Multiple shock-absorbing pads are provided, and multiple shock-absorbing pads are installed in multiple slots of the same mounting group to form a clamping ring adapted to the diameter of the electron tube.

[0006] By adopting the above technical solution, when the damping pads are installed in the slots of the same mounting group, a clamping ring adapted to the diameter of the electron tube is formed between multiple damping pads; when the damping pads are installed in the slots of different mounting groups, the diameter of the clamping ring formed between multiple damping pads changes accordingly, which can match the outer wall of electron tubes of different diameters, realizing the fitting of electron tubes of different diameters; the damping pads are snapped into the slots and protrude from the slots, and after the damping ring is fitted on the electron tube, the damping pads abut against the outer wall of the electron tube. When the vibration generated by the sound is transmitted to the substrate, the damping pads absorb the vibration energy through their own deformation, weaken the vibration of the electron tube, and thus suppress the microphone effect.

[0007] Preferably, the outer wall of the substrate is provided with heat dissipation columns, which are arranged along the height direction of the outer wall of the substrate; multiple heat dissipation columns are provided, and the multiple heat dissipation columns are evenly spaced along the outer wall of the substrate.

[0008] By adopting the above technical solution, multiple heat dissipation columns are arranged at uniform intervals along the height direction on the outer side wall of the substrate, which can enhance the heat dissipation of the substrate to the electron tube.

[0009] Preferably, the end of the substrate near the bottom pin of the electron tube is coated with an insulating coating.

[0010] By adopting the above technical solution, since the substrate is usually made of metal, after the damping ring is sleeved on the electron tube, the damping ring may come into contact with the charged body in the speaker during the operation of the electron tube, causing the damping ring to generate a circuit and form a magnetic field that affects the internal electrodes of the electron tube, resulting in electromagnetic interference; through the insulating coating, the damping ring can be prevented from directly contacting the charged body and generating a circuit.

[0011] Preferably, the shock-absorbing pad is made of rubber material and injection molded into a cylindrical shape that fits the slot.

[0012] By adopting the above technical solutions, rubber materials possess the physical properties of high elasticity and high damping. High elasticity allows them to deform rapidly when subjected to vibration, absorbing vibration energy; high damping enables the vibration energy generated during deformation to be converted into heat energy and other forms of dissipation, reducing vibration rebound and transmission; it also has a certain heat dissipation capacity.

[0013] Preferably, the substrate is a cylinder with two through ends, and the arrangement and number of multiple slots in each slot group on the inner wall of the substrate are the same; the distance between the multiple slots of the slot group and the center of the substrate gradually increases in a clockwise or counterclockwise direction along the inner wall of the substrate.

[0014] By adopting the above technical solution, the substrate is a cylinder with two through ends. The arrangement and number of multiple slots in each slot group on the inner side wall of the substrate are the same. At this time, the distance between the slot and the center of the substrate gradually increases along the inner side wall of the substrate in a clockwise or counterclockwise direction. That is, when multiple shock-absorbing pads are installed on the slots of multiple mounting groups, the clamping ring formed between the multiple shock-absorbing pads has a maximum radius and a minimum radius, forming a radius range to adapt to the electron tube within the radius range.

[0015] Preferably, there are five card slot groups, and the distance between each card slot group and the adjacent card slot group is equal.

[0016] By adopting the above technical solution, five slot groups are evenly spaced along the circumference of the base, with adjacent slot groups having an included angle of 72°, forming a five-point clamping structure. According to the mechanical positioning principle, the five-point clamping can make the force on the electron tube evenly distributed on the circumference, avoiding excessive local force that could cause deformation of the electron tube shell, or insufficient local force that could cause loosening. The evenly distributed slot groups ensure that the center of the clamping ring coincides with the center of the base, thereby making the electron tube coaxial with the base after installation, preventing uneven vibration transmission due to eccentricity, and ensuring stable shock absorption effect.

[0017] Preferably, each of the slot groups includes three slots, and the distances of the three slots from the center of the base are different. The three slots with different distances from the center of the base in all the slot groups together constitute three mounting groups. Multiple shock-absorbing pads are installed on the slots of the three mounting groups to form three sets of clamping rings. The diameter range of the three sets of clamping rings is 19.5mm-22mm.

[0018] By adopting the above technical solution, multiple shock-absorbing pads are respectively installed on the three sets of mounting slots formed by three slots to form three sets of clamping rings. The diameter range of the three sets of clamps is limited to 19.5mm-22mm. Since the shock-absorbing pads are elastic, the diameter range can be smoothly transitioned when mounting electron tubes. Specifically, the clamping ring formed by the shock-absorbing pads installed in the center slot of the inner wall is suitable for electron tubes with a diameter of 19.5-20.3mm; the clamping ring formed by the shock-absorbing pads installed in the slots at the center and middle of the edge of the inner wall is suitable for electron tubes with a diameter of 20.3-21.2mm; and the clamping ring formed by the shock-absorbing pads installed in the slots at the edge of the inner wall is suitable for electron tubes with a diameter of 21.2-22.0mm. The diameter range of 19.5mm-22mm covers the outer diameter specifications of common electron tubes within this range. By adjusting the position of the slots where the shock-absorbing pads are engaged, the compatibility with electron tubes within this specification range can be directly adjusted, realizing the adaptation of the shock-absorbing pads to electron tubes of different diameters.

[0019] In summary, this application includes at least one of the following beneficial technical effects: 1. When the damping pads are installed in the slots of the same mounting group, a clamping ring adapted to the diameter of the vacuum tube is formed between multiple damping pads; when the damping pads are installed in the slots of different mounting groups, the diameter of the clamping ring formed between multiple damping pads changes accordingly, which can match the outer wall of vacuum tubes of different diameters, realizing the fitting of vacuum tubes of different diameters; the damping pads are snapped into the slots and protrude from the slots, and after the damping ring is fitted onto the vacuum tube, the damping pads abut against the outer wall of the vacuum tube. When the vibration generated by the speaker is transmitted to the substrate, the damping pads absorb the vibration energy through their own deformation, weaken the vibration received by the vacuum tube, and thus suppress the microphone effect; at the same time, they can absorb the heat of the vacuum tube and help dissipate heat; 2. Multiple heat dissipation columns are evenly spaced along the height direction on the outer wall of the substrate, which can enhance the heat dissipation of the substrate to the electron tube; 3. Since the substrate is usually made of metal, after the damping ring is fitted onto the vacuum tube, the damping ring may come into contact with charged parts in the speaker during the operation of the vacuum tube, causing the damping ring to generate a circuit and form a magnetic field that affects the internal electrodes of the vacuum tube, resulting in electromagnetic interference; through the insulating coating, the damping ring can be prevented from directly contacting charged parts and generating a circuit.

[0022] The following is in conjunction with the appendix Figure 1 -Appendix Figure 4 This application will be described in further detail.

[0023] This application discloses a shock-absorbing ring adapted to electron tubes of different diameters.

[0024] refer to Figure 1 and Figure 2A shock-absorbing ring adapted to electron tubes of different diameters includes a base 1, which is a cylinder with two through ends. Multiple slot groups 2 are provided on the inner wall of the base 1, and the slot groups 2 are evenly spaced along the inner wall of the base 1. Each slot group 2 includes multiple slots 3, which are grooves formed on the inner wall of the slot group 2 along its own height direction, extending and penetrating the top and bottom of the base 1. The arrangement and number of slots 3 in each slot group 2 on the inner wall of the base 1 are identical. All the slots 3 in the slot group 2 that are at the same distance from the center of the base 1 constitute a mounting group 4. The slots 3 in each mounting group 4 are arranged to form a circle with the center of the base 1 as the center. All the slots 3 in the slot group 2 that are at different distances from the center of the base 1 constitute multiple mounting groups 4. The diameters of the circles formed by the slots 3 in the multiple mounting groups 4 are different. The distance between the multiple slots 3 in the slot group 2 and the center of the base 1 gradually increases along the inner sidewall of the base 1 in a clockwise or counterclockwise direction.

[0025] It also includes a shock-absorbing pad 5, which is made of rubber material and injection molded into a cylindrical shape that fits the slot 3. The shock-absorbing pad 5 is inserted into the slot 3 and protrudes from the slot 3. Multiple shock-absorbing pads 5 are provided, and multiple shock-absorbing pads 5 are installed in multiple slots 3 of the same set of mounting group 4 to form a clamping ring 6 that fits the diameter of the electron tube.

[0026] In other embodiments, the shock-absorbing pad 5 is made by uniformly incorporating graphite powder or aluminum powder into a rubber material, so that the shock-absorbing pad 5 has both shock absorption and heat dissipation functions. The shock-absorbing pad 5 can absorb the heat of the electron tube and conduct the heat of the electron tube to the substrate 1, thereby realizing the heat dissipation function of the electron tube.

[0027] When the shock-absorbing pads 5 are installed in the slots 3 of different mounting groups 4, the diameter of the clamping rings 6 formed between the multiple shock-absorbing pads 5 changes accordingly, which can match the outer walls of electron tubes with different outer diameter specifications, thus achieving adaptation to electron tubes of different specifications.

[0028] In this embodiment, the inner wall of the substrate 1 has a flower-shaped cross-section with five petals, each petal being an arc-shaped groove on the inner wall of the substrate 1. Five sets of slot groups 2 are provided, each set located within one of the five grooves. The distance between each set of slot groups 2 and its adjacent set is equal. Each slot group 2 includes three slots 3, each slot 3 at a different distance from the center of the substrate 1. The distance between the three slots 3 and the center of the substrate 1 gradually increases counterclockwise along the inner wall of the substrate 1. The slots 3 in each slot group 2 that are at the same distance from the center of the substrate 1 form a circular mounting group 4. Since each slot group 2 includes three slots 3, the slots 3 at different distances from the center of the substrate 1 in all slot groups 2 together form three mounting groups 4 with different diameters. Multiple shock-absorbing pads 5 are respectively installed on the slots 3 of the three mounting groups 4 to form three sets of clamping rings 6. The diameter of the three sets of clamping rings 6 ranges from 19.5mm to 22mm. Figure 2 The clamping ring 6, consisting of shock-absorbing pads 5 in the slot 3 installed at the edge of the inner wall of the arc-shaped groove, is adapted to electron tubes with a diameter of 19.5-20.3mm; (Reference) Figure 3 The clamping ring 6, composed of shock-absorbing pads 5 and a slot 3 located at the center of the inner wall and the middle of the edge of the arc-shaped groove, is adapted to electron tubes with a diameter of 20.3-21.2mm; (Reference) Figure 4 The clamping ring 6, consisting of the shock-absorbing pads 5 of the slot 3 installed in the center of the inner side wall of the arc-shaped groove, is adapted to electron tubes with a diameter of 21.2-22.0mm.

[0029] refer to Figure 1 The outer wall of the substrate 1 is integrally formed with heat dissipation columns 7, which are arranged along the height direction of the outer wall of the substrate 1. Multiple heat dissipation columns 7 are arranged in a circular array around the circumference of the substrate 1. The heat dissipation columns 7 can enhance the heat dissipation of the electron tube by the substrate 1.

[0030] The end of the substrate 1 near the bottom pin of the vacuum tube is coated with an insulating coating (not shown in the figure). Since the substrate 1 is usually made of metal, after the damping ring is fitted onto the vacuum tube, the damping ring may come into contact with charged parts in the speaker during the operation of the vacuum tube, causing the damping ring to generate a circuit and form a magnetic field that affects the internal electrodes of the vacuum tube, resulting in electromagnetic interference. The insulating coating can prevent the damping ring from directly contacting charged parts and generating a circuit.

[0031] The implementation principle of this application embodiment is as follows: multiple shock-absorbing pads 5 are installed in the slots 3 of one of the slot groups 2 in the multiple mounting groups 4, and then the electron tube is slowly inserted into the shock-absorbing ring; if the electron tube is too tight or too loose, the position of the slot 3 where the shock-absorbing pads 5 are installed is adjusted so that the diameter of the clamping ring 6 formed by the multiple shock-absorbing pads 5 is adapted to the diameter of the electron tube currently being installed, and finally the electron tube abuts against the shock-absorbing pads 5, completing the installation of the shock-absorbing ring on the electron tube.

[0032] In summary, when the damping pads 5 are installed in the slots 3 of different mounting groups 4, the diameter of the clamping rings 6 formed between the multiple damping pads 5 changes accordingly, which can match the outer walls of electron tubes of different diameters, thus realizing the fitting of electron tubes of different diameters; the damping pads 5 are snapped into the slots 3 and protrude from the slots 3, and after the damping rings are fitted onto the electron tubes, the damping pads 5 abut against the outer wall of the electron tubes. When the vibration generated by the sound is transmitted to the base 1, the damping pads 5 absorb the vibration energy through their own deformation, weaken the vibration of the electron tubes, and thus suppress the microphone effect.

[0033] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
