Description

Technical Field

[0001] This utility model relates to the field of record player technology, and in particular to a vinyl record player and a record player set. Background Technology

[0002] A record player, also known as a phonograph, is a sound playback device that stores sound in curved grooves etched acoustically onto the surface of a vinyl record. To play music, the record is placed on the turntable, which rotates the record beneath the stylus. The audio information collected by the stylus is amplified by the circuitry and then output to a device with a speaker to play the music.

[0003] Currently, for separate record players, since the record player itself doesn't have a speaker, a separate speaker is usually required for connection. This ignores the impact of speaker vibrations on the record player. However, in practical applications, the record player and speaker are usually placed on the same table. When the speaker vibrates, the vibration is transmitted through the table to the record player, causing sound distortion, noise, and ringing, thus affecting the sound quality of the record player. Utility Model Content

[0004] This utility model provides a vinyl record player and record player set that can reduce the impact of vibration on sound quality and improve the playback experience.

[0005] This utility model discloses a vinyl record player, comprising: a support plate on which a tonearm assembly and a turntable assembly are disposed; a base plate on the side of the support plate opposite to the tonearm assembly; and a vibration damping assembly comprising a first vibration damping module and a second vibration damping module connected to each other, the first vibration damping module being connected to the base plate, and the second vibration damping module being connected between the support plate and the base plate; wherein the first vibration damping module is used to contact a placement platform.

[0006] Optionally, the first vibration damping module includes a support foot, a first vibration damping spring, and a first connector, wherein the first connector is connected between the support foot and the second vibration damping module, and the first vibration damping spring abuts against the support foot and the base plate.

[0007] Optionally, the base plate is concentrically provided with a first limiting ring groove and a limiting groove, and the limiting groove is located on the outer side of the first limiting ring groove in the axial direction; the support foot is provided with a second limiting ring groove corresponding to the first limiting ring groove, the two ends of the first damping spring are respectively located in the first limiting ring groove and the second limiting ring groove, and part of the support foot is accommodated in the limiting groove.

[0008] Optionally, a receiving groove is provided on the side of the support foot away from the base plate, and a vibration damping pad is provided in the receiving groove, with the vibration damping pad protruding from the receiving groove.

[0009] Optionally, the second vibration damping module includes a connecting seat, a connecting plate, a second vibration damping spring, and a second connecting member. The connecting seat includes a seat body with a receiving cavity formed inside. A protruding edge is formed at the opening of the receiving cavity. The connecting plate is connected to the support plate and has a through hole. The protruding edge is engaged with the outer ring of the through hole. A portion of the second vibration damping spring is housed in the receiving cavity, and the second vibration damping spring abuts against the seat body and the support plate.

[0010] Optionally, a damping pad is further provided between the protruding edge and the connecting plate. The outer circumferential array of the protruding edge is provided with multiple notches. The damping pad includes an annular washer and a rim provided around the annular washer. Multiple locking protrusions are formed on the inner side of the rim. The multiple locking protrusions and the multiple notches are locked in a one-to-one manner, and the annular washer abuts against the protruding edge and the connecting plate.

[0011] Optionally, the first connector and the second connector are bolts, the base is provided with a first nut, the support plate is provided with a second nut, the first connector is threadedly connected to the first nut, and the second connector is threadedly connected to the second nut.

[0012] Optionally, the first damping spring and the second damping spring have different outer diameters, and / or the first damping spring and the second damping spring have different thicknesses.

[0013] Optionally, the record player further includes a cover, which is rotatably or snap-fitted to the support plate.

[0014] This utility model also discloses a record player kit, including a speaker and a vinyl record player as described in any one of the above descriptions, wherein the speaker can be connected to the vinyl record player wirelessly or via a wired connection.

[0015] The beneficial effects of the record player and record player kit provided by this utility model embodiment are as follows: By setting the support plate and the base plate in a layered structure, and connecting the support plate and the base plate through a vibration damping component, the first vibration damping module is connected to the base plate during connection, and the first vibration damping module is used to contact the placement platform. This can specifically block the initial input of external vibration, solving the problem of easy vibration transmission in traditional record players due to rigid contact with the platform. At the same time, by setting a dual vibration damping structure formed by the first vibration damping module and the second vibration damping module, with the second vibration damping module connected between the support plate and the base plate, the direct transmission of vibration caused by rigid contact is avoided. A vibration transmission path of "placement platform → first vibration damping module → base plate → second vibration damping module → support plate" is constructed. In this path, the first vibration damping module first absorbs and attenuates the vibration from the placement platform (mainly the vibration transmitted by the speaker through the table surface). The second vibration damping module absorbs and attenuates the residual vibration after passing through the base plate, significantly reducing the vibration energy ultimately transmitted to the support plate (and the tonearm and turntable assemblies above it). This fundamentally reduces the impact of vibration on sound quality, thereby avoiding sound distortion, noise, and ringing, and significantly improving the sound quality stability of the record player.

Detailed Implementation

[0024] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0025] like Figure 1 and Figure 2 As shown, this utility model embodiment provides a record player 100, including: a support plate 110, on which a tonearm assembly 112 and a turntable assembly 114 are disposed; a base plate 120, which is disposed on the side of the support plate 110 away from the tonearm assembly 112; and a vibration damping assembly 130, which includes a first vibration damping module 132 and a second vibration damping module 134 connected to each other. The first vibration damping module 132 is connected to the base plate 120, and the second vibration damping module 134 is connected between the support plate 110 and the base plate 120. The first vibration damping module 132 is used to contact the placement platform.

[0026] Specifically, the support plate 110 is the main load-bearing component of the record player 100. A tonearm assembly 112 and a turntable assembly 114 are mounted on its surface. The tonearm assembly 112 and turntable assembly 114 adopt existing structural forms and are key components for the record player 100 to achieve its playback function. The turntable assembly 114 is used to hold the vinyl record and drive its rotation, while the tonearm assembly 112 reads the track information from the record through the cartridge. The base plate 120 is located on the side of the support plate 110 opposite to the tonearm assembly 112, i.e., below the support plate 110, forming the bottom support structure of the record player 100, creating a vertically opposite layout with the support plate 110.

[0027] When vibration damping components 130 are installed at the support plate 110 and the base plate 120, the first vibration damping module 132 is directly connected to the base plate 120, and its main function is to contact the placement platform (such as a desktop, shelf, etc.) where the record player 100 is placed, becoming the connection medium between the record player and the external placement platform; the second vibration damping module 134 is connected between the support plate 110 and the base plate 120, located between the upper and lower structures inside the record player, to form a dual vibration damping mode.

[0028] The record player 100 provided in this application embodiment adopts a layered structure for the support plate 110 and the base plate 120, and connects the support plate 110 and the base plate 120 through a vibration damping assembly 130. During connection, the first vibration damping module 132 is connected to the base plate 120, and the first vibration damping module 132 is used to contact the placement platform, which can specifically block the initial input of external vibration, solving the problem of easy vibration transmission caused by rigid contact with the platform in traditional record players. At the same time, by setting up a dual vibration damping structure formed by the first vibration damping module 132 and the second vibration damping module 134, the second vibration damping module 134 is connected between the support plate 110 and the base plate 120, avoiding direct vibration transmission caused by rigid contact. A vibration transmission path of "placement platform → first vibration damping module 132 → base plate 120 → second vibration damping module 134 → support plate 110" is constructed. In this process, the first damping module 132 first absorbs and attenuates the vibrations from the placement platform (mainly the vibrations transmitted from the speaker 210 through the platform). The second damping module 134 then absorbs and attenuates the residual vibrations after passing through the base plate 120, significantly reducing the vibration energy ultimately transmitted to the support plate 110 (and the tonearm assembly 112 and turntable assembly 114 on it). This fundamentally reduces the impact of vibration on sound quality, thereby avoiding sound distortion, noise, and ringing, and significantly improving the sound quality stability of the record player 100.

[0029] like Figure 2 , Figure 3 and Figure 4 As shown, the first vibration damping module 132 includes a support foot 1322, a first vibration damping spring 1324 and a first connector 1326. The first connector 1326 is connected between the support foot 1322 and the second vibration damping module 134, and the first vibration damping spring 1324 is supported between the support foot 1322 and the base plate 120.

[0030] Specifically, the support foot 1322 bears the fundamental role of supporting the weight of the entire record player 100. The first connector 1326 serves as a connecting medium, passing through the base plate 120 to connect the support foot 1322 to the second damping module 134, forming a unified damping system. The first damping spring 1324 is located between the support foot 1322 and the base plate 120, with its two ends abutting against both ends. This ensures the first damping spring 1324 is in a pre-compressed state, absorbing vibrational energy through its elastic deformation and providing elastic support to the base plate 120. Compared to simple rigid support, the spring's elastic properties effectively cope with vibrations of different frequencies and intensities, improving its adaptability to external vibrations.

[0031] like Figure 3 and Figure 4 As shown, a first limiting annular groove 122 and a limiting groove 124 are concentrically arranged on the base plate 120, and the limiting groove 124 is located on the outer side of the first limiting annular groove 122 in the axial direction; a second limiting annular groove 1322a corresponding to the first limiting annular groove 122 is provided on the support foot 1322, and the two ends of the first damping spring 1324 are respectively located in the first limiting annular groove 122 and the second limiting annular groove 1322a, and part of the support foot 1322 is accommodated in the limiting groove 124.

[0032] Specifically, the first limiting annular groove 122 and the second limiting annular groove 1322a form radial limits on both ends of the first damping spring 1324. This helps prevent the first damping spring 1324 from tilting, falling off, or excessively shifting when using the record player 100, ensuring that the first damping spring 1324 is always in the preset working position and guaranteeing the stability of the damping effect. Part of the support foot 1322 is housed in the limiting groove 124, which forms a radial constraint on the support foot 1322, preventing excessive displacement or shaking of the support foot 1322 in the horizontal direction (radial), thereby reducing additional vibration caused by structural instability and improving the stability of the record player 100 during operation. In addition, the concentric arrangement of the first limiting annular groove 122 and the limiting groove 124 facilitates the compactness of the support foot 1322, the first damping spring 1324, and the base plate 120, simplifies the connection, and reduces assembly difficulty.

[0033] like Figure 3 and Figure 4 As shown, a receiving groove is provided on the side of the support foot 1322 away from the base plate 120, and a vibration damping pad 1328 is provided in the receiving groove, with the vibration damping pad 1328 protruding from the receiving groove.

[0034] Specifically, the receiving groove provides installation space for the vibration damping pad 1328, ensuring that the vibration damping pad 1328 can be stably fixed on the support foot 1322; the vibration damping pad 1328 protruding from the receiving groove means that its contact with the placement platform is flexible, further enhancing the vibration damping effect. The vibration damping pad 1328 is usually made of elastic materials such as rubber and silicone, which have good vibration damping and cushioning performance. Felt pads can also be used, which also have a vibration damping effect.

[0035] like Figure 2 , Figure 3 and Figure 4 As shown, the second vibration damping module 134 includes a connecting seat 1342, a connecting plate 1344, a second vibration damping spring 1346, and a second connecting member 1348. The connecting seat 1342 includes a seat body 1342a, a receiving cavity 1342b is formed in the seat body 1342a, and a protruding edge 1342c is formed at the opening of the receiving cavity 1342b. The connecting plate 1344 is connected to the support plate 110, and a through hole is provided on the connecting plate 1344. The protruding edge 1342c is held in the outer ring of the through hole. Part of the second vibration damping spring 1346 is received in the receiving cavity 1342b, and the second vibration damping spring 1346 abuts between the seat body 1342a and the support plate 110.

[0036] Specifically, the protruding edge 1342c of the connecting seat 1342 is engaged with the outer ring of the through hole in the connecting plate 1344, which not only achieves a reliable connection between the connecting seat 1342 and the connecting plate 1344, but also retains a certain relative displacement space through the engaging method (which is beneficial for the second damping spring 1346 to reduce vibration by utilizing the energy loss of its own deformation), thus avoiding the direct transmission of vibration caused by rigid connection. The accommodating cavity 1342b partially accommodates the second damping spring 1346, which can form a radial limit on the second damping spring 1346, preventing the second damping spring 1346 from excessively deflecting during vibration and ensuring its stable operation. In this way, after the vibration passes through the first damping module 132 and the base plate 120, the residual vibration will be transmitted to the second damping module 134. The second damping spring 1346 absorbs and attenuates the vibration energy again, which greatly reduces the vibration transmitted to the support plate 110 (and tonearm assembly 112 and turntable assembly 114). Compared with a single damping mode, it can more effectively block the transmission of vibration.

[0037] like Figure 3 and Figure 4As shown, a damping pad 1345 is also provided between the protruding edge 1342c and the connecting plate 1344. The outer circumferential array of the protruding edge 1342c is provided with multiple notches 1342d. The damping pad 1345 includes an annular washer 1345a and a perimeter 1345b provided around the annular washer 1345a. Multiple locking protrusions 1345c are formed on the inner side of the perimeter 1345b. The multiple locking protrusions 1345c are locked in one-to-one with the multiple notches 1342d, and the annular washer 1345a abuts against the protruding edge 1342c and the connecting plate 1344.

[0038] Specifically, a damping pad 1345 is added between the protruding edge 1342c and the connecting plate 1344. Multiple notches 1342d are arranged in a circular array on the outer circumference of the protruding edge 1342c. The damping pad 1345 includes an annular washer 1345a and a surrounding edge 1345b. Multiple locking protrusions 1345c on the inner side of the surrounding edge 1345b correspond one-to-one with the notches 1342d. The annular washer 1345a abuts against the protruding edge 1342c and the connecting plate 1344. The damping pad 1345, positioned between the protruding edge 1342c and the connecting plate 1344, forms a buffer between the connecting seat 1342 and the connecting plate 1344 through its own elastic deformation, further attenuating the vibration transmitted from the connecting seat 1342 to the connecting plate 1344 (and subsequently to the support plate 110). This structure enables the second vibration damping module 134 to form a composite secondary vibration damping mode, improving the absorption effect of residual vibration, especially the absorption effect of high-frequency micro vibration. Among them, the damping pad 1345 is usually made of elastic materials such as rubber and silicone. The cooperation between the protrusion 1345c and the notch 1342d ensures that the position of the damping pad 1345 between the protrusion 1342c and the connecting plate 1344 is fixed, preventing it from shifting during vibration.

[0039] In optional embodiments of this application, such as Figure 3 and Figure 4 As shown, the first connector 1326 and the second connector 1348 are bolts. The seat 1342a is provided with a first nut 1329, and the support plate 110 is provided with a second nut 1349. The first connector 1326 is threadedly connected to the first nut 1329, and the second connector 1348 is threadedly connected to the second nut 1349.

[0040] Specifically, the threaded connection of the bolt and nut has high connection strength, ensuring a firm connection between the first vibration damping module 132 and the second vibration damping module 134, and between the second vibration damping module 134 and the support plate 110, preventing loosening during long-term vibration or handling. Simultaneously, the pre-compression of the springs (first vibration damping spring 1324 and second vibration damping spring 1346) can be adjusted by rotating the bolts, thereby adjusting the vibration damping stiffness of the vibration damping assembly 130 to adapt to different placement platforms (such as desktops with different vibration characteristics) or usage scenarios, improving the product's adaptability.

[0041] In an optional embodiment of this application, the outer diameters of the first damping spring 1324 and the second damping spring 1346 are different, and / or the thicknesses of the first damping spring 1324 and the second damping spring 1346 are different.

[0042] Specifically, the first damping module 132 primarily addresses external vibrations from the placement platform (such as vibrations transmitted from the speaker 210), which are typically high-intensity and have a wide frequency range (including low and high frequencies). The second damping module 134 primarily addresses residual vibrations after primary damping, which are lower in intensity and have relatively concentrated frequencies. By using springs with different outer diameters and / or thicknesses, the first damping spring 1324 can have higher stiffness to cope with strong vibrations, while the second damping spring 1346 has lower stiffness to accurately absorb residual vibrations, thus improving the overall targeting and efficiency of the damping system. By using the first damping spring 1324 and the second damping spring 1346 with different outer diameters and thicknesses, a wider range of vibration frequencies can be covered. Furthermore, in conjunction with the damping pad 1328 and the cushioning pad 1345, the damping frequency range is further broadened, making damping more comprehensive and efficient, thereby ensuring the sound quality of the record player 100. It should be noted that when the first damping spring 1324, the second damping spring 1346, the damping pad 1328, and the damping pad 1345 absorb vibration, they will all undergo a certain amount of elastic deformation. However, the above deformation is microscopic and invisible. While absorbing vibration, it will not affect the stability of the overall structure.

[0043] like Figure 1 As shown, the record player 100 also includes a cover 140, which is rotatably connected to or snapped into the support plate 110.

[0044] Specifically, the cover 140 is typically made of a transparent or translucent material (such as acrylic or glass), and its main function is to cover the support plate 110 and house the tonearm assembly 112 and the turntable assembly 114 inside. A rotatable connection means that the cover 140 can rotate and open around the edge of the support plate 110, while a snap-fit ​​connection means that the cover 140 can be placed directly on or removed from the support plate 110, forming a detachable structure to meet different usage environments or needs.

[0045] This utility model also discloses a record player kit 200, including a speaker 210 and the vinyl record player 100 in the aforementioned embodiments. The speaker 210 can be connected to the vinyl record player 100 via wired or wireless connection.

[0046] Specifically, the turntable 100 converts the analog signals from the vinyl record into electrical signals, while the speaker 210 amplifies these electrical signals and plays them as sound. This combination provides users with a higher quality and more complete music experience. Wired connection is suitable for users with high sound quality requirements, maximizing the reproduction of the sound details of the vinyl record. Wireless connection is suitable for users who prioritize convenience. For wired connection, simply connect the turntable 100 and speaker 210 to their respective interfaces. For wireless connection, Bluetooth can be used.

[0047] It should be understood that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Those skilled in the art can modify the technical solutions described in the above embodiments, or make equivalent substitutions for some of the technical features; and all such modifications and substitutions should fall within the protection scope of the appended claims of this utility model.
