Description

Technical Field

[0001] This utility model relates to the field of record player technology, specifically to a record player mechanism with an anti-noise structure. Background Technology

[0002] An antique record player is a primitive sound playback device. Its sound is stored in the arc-shaped grooves carved into the surface of the record using acoustic methods. Most record players consist of a speaker cabinet and a turntable mechanism. The turntable mechanism has a phono preamp, the phono preamp has a cartridge, and the cartridge has a stylus. As the core component for reading audio information, the stylus's tip closely contacts the grooves of the record as it rotates. It moves with the undulations of the sound signature, converting these minute physical changes into electrical signals. These electrical signals are then processed by the amplifier and speakers inside the record player, ultimately transforming them into the sound we can hear.

[0003] Existing record players require stable operating conditions to play sound. When the speaker is playing sound, because the speaker is fixed to the cabinet, if the decibel level of the speaker inside the cabinet exceeds a certain value, it will cause air vibration, which will cause the cartridge arm to vibrate. This will result in unstable contact between the stylus and the record, producing additional vibrations. These additional vibrations will be captured and amplified by the cartridge pickup, thus producing a buzzing sound, which will greatly reduce the product experience. Existing record players cannot meet the needs of users and are not conducive to improving the competitiveness of the product. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides a turntable mechanism with an anti-noise structure, which solves the problem that in existing record players, the turntable recognition head is prone to up-and-down vibration, resulting in unstable contact between the stylus and the record and producing noise.

[0005] This utility model discloses a turntable mechanism with an anti-resonance structure, comprising a turntable mechanism assembly and a cartridge mechanism assembly. The cartridge mechanism assembly includes a cartridge frame and a tonearm assembly. The tonearm assembly includes a tonearm rod, a tonearm return member, and a tonearm buffer elastic member. The tonearm rod is positioned above the cartridge frame, while the tonearm return member and the tonearm buffer elastic member are positioned below the cartridge frame. A tonearm rotating rod is fixedly mounted on the tonearm rod, and the tonearm buffer elastic member is sleeved on the tonearm rotating rod. The cartridge frame has a rotating through hole, in which the tonearm rotating rod is positioned. The lower end of the tonearm rotating rod has a fixing part that cooperates with the tonearm return member for installation. The tonearm return member is sleeved on the fixing part. The upper and lower ends of the tonearm buffer elastic member are limited by the lower end face of the cartridge frame and the upper end face of the tonearm return member, respectively. The tonearm buffer elastic member can improve the stability of the relative position between the tonearm rotating rod and the cartridge frame.

[0006] This invention is further improved by providing a counterweight on the tonestick assembly, which can reduce the probability of the tonestick assembly vibrating relative to the cartridge mechanism.

[0007] This utility model is further improved by fixing the counterweight to the lower end face of the tonearm return component.

[0008] This utility model is further improved, and the turntable mechanism assembly includes a mechanism frame, a rotary drive motor, a belt, a rotary tray, a turntable center shaft, and a return drive component. The return drive component can cooperate with the tonearm return component to control the tonearm to return to its original position.

[0009] This utility model is further improved by fixing part being a foolproof plane set at the lower end of the phono stage, tonestick return part being provided with tonestick hole that cooperates with phono stage, and tonestick hole inner wall being provided with positioning wall that cooperates with foolproof plane, and foolproof plane being provided with anti-detachment boss, anti-detachment boss being set below tonestick hole, anti-detachment boss being able to support tonestick return part.

[0010] This utility model is further improved by having two anti-detachment protrusions, which are symmetrically arranged on both sides of the lower end of the phono stage. The lower end of the phono stage is hollow, and deformation buffer notches are provided on both sides of the fixing part between the two anti-detachment protrusions. The deformation buffer notches can provide space for deformation when the lower end of the phono stage shrinks.

[0011] This utility model is further improved by providing a hemispherical arc surface at the lower end of the phono stage, and the hemispherical arc surface extends from the end of the phono stage to the outer surface of the anti-dislodgement boss.

[0012] This utility model is further improved by using a spring as the elastic element for the tonearm buffer.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model provides a turntable mechanism with an anti-ringing structure. This structure effectively solves the problem in existing record players where the turntable head easily vibrates up and down, leading to unstable contact between the stylus and the record, resulting in ringing. By using this product structure, the fixing part secures the tonearm return component to the cartridge rotating rod, and the tonearm buffer elastic component is positioned between the cartridge mechanism frame and the tonearm return component. This fixes the relative positions of the cartridge rotating rod, the cartridge mechanism frame, and the tonearm return component, effectively reducing the possibility of axial movement of the cartridge rotating rod on the cartridge mechanism frame, improving the stability of the cartridge rod's operation, and thus ensuring the stability of the contact between the stylus and the record, reducing the possibility of ringing, ensuring the normal operation of the record player, and improving the user experience.

[0021] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0022] like Figure 1-4As shown, this utility model discloses a turntable mechanism with an anti-ringing structure, including a turntable mechanism assembly and a cartridge mechanism assembly. The cartridge mechanism assembly includes a cartridge frame 1 and a tonearm assembly. The tonearm assembly includes a tonearm 2, a tonearm return member 3, and a tonearm buffer elastic member 4. The tonearm 2 is positioned above the cartridge frame 1, and the tonearm return member 3 and tonearm buffer elastic member 4 are positioned below the cartridge frame 1. A cartridge rotation rod 5 is fixedly mounted on the tonearm 2, and the tonearm buffer elastic member 4 is sleeved on... The phono stage 5 has a rotating through hole on the phono frame 1. The phono stage 5 is set in the rotating through hole, and the lower end of the phono stage 5 has a fixing part that cooperates with the tonestick return piece 3. The tonestick return piece 3 is sleeved on the fixing part. The upper and lower ends of the tonestick buffer elastic piece 4 are limited by the lower end face of the phono frame 1 and the upper end face of the tonestick return piece 3, respectively. The tonestick buffer elastic piece 4 can improve the stability of the relative position between the phono stage 5 and the phono frame 1.

[0023] The tonestick return member 3 is fixed to the phono head 5 by the fixing part. The tonestick buffer elastic member 4 is set between the phono head mechanism frame 1 and the tonestick return member 3. This can fix the relative position between the phono head 5, the phono head mechanism frame 1 and the tonestick return member 3, effectively reducing the possibility of axial movement of the phono head 5 on the phono head mechanism frame 1, avoiding vibration, improving the stability of the phono head working process, thereby ensuring the stability of the contact between the stylus and the record, reducing the possibility of the device producing noise, ensuring the normal use of the record player and improving the user experience.

[0024] The tonestick assembly is equipped with a counterweight 6. By setting the counterweight 6, the probability of the tonestick assembly vibrating due to air vibration caused by loud sound between the tonestick assembly and the cartridge frame 1, thus causing the tonestick assembly to vibrate and the machine to produce a sound, can be further reduced, thus suppressing tonestick assembly vibration.

[0025] The counterweight 6 is fixedly installed on the lower end face of the tonestick return component 3, which makes the installation of the component more convenient.

[0026] The counterweight 6 is bonded to the lower end face of the tonestick return component 3.

[0027] The turntable mechanism assembly includes a mechanism frame 7, a rotary drive motor 8, a belt 9, a rotary tray 10, a turntable center spindle 11, and a return drive component 12. The return drive component 12, in conjunction with the tonearm return component 3, controls the phono preamp 2 to return to its original position.

[0028] The belt 9 is mounted on the rotating tray 10. The moving end of the rotary drive motor 8 is connected to the belt 9. The mechanism frame 7 is provided with a tray placement position that cooperates with the rotating tray 10. The rotating tray 10 is mounted on the central rotating shaft 11 of the turntable. The rotary drive motor 8 drives the belt 9 to rotate, and the belt 9 drives the rotating tray 10 to rotate.

[0029] The fixing part is a foolproof plane 51 set at the lower end of the phono stage 5. The tonestick return member 3 is provided with a tonestick hole that cooperates with the phono stage 5, and the inner wall of the tonestick hole is provided with a positioning wall that cooperates with the foolproof plane 51. The foolproof plane 51 is provided with an anti-drop boss 52, which is located below the tonestick hole. The anti-drop boss 52 can support the tonestick return member 3 and prevent the tonestick return member 3 from falling downward.

[0030] There are two anti-detachment protrusions 52, which are symmetrically arranged on both sides of the lower end of the phono stage 5. The lower end of the phono stage 5 is a hollow structure, and deformation buffer notches 53 are provided on both sides of the fixing part between the two anti-detachment protrusions 52. The deformation buffer notches 53 can provide space for deformation of the lower end of the phono stage 5 when the size shrinks.

[0031] By setting two anti-detachment bosses 52, the stability of the tonestick return member 3 on the phono stage 5 can be further improved.

[0032] The deformation buffer notch 53 can compress and narrow the cross-section of the lower end of the phono stage 5, making it easier for the stage return piece 3 to be fitted onto the fixed part.

[0033] The lower end of the phono stage 5 is provided with a hemispherical arc surface 54, and the hemispherical arc surface 54 extends from the end of the phono stage 5 to the outer surface of the anti-drop boss 52.

[0034] The extension of the hemispherical arc surface 54 to the outer surface of the anti-detachment protrusion 52 can further improve the convenience of the silent rotation of the tonestick buffer elastic element 4 and the tonestick return element 3.

[0035] The 4th spring is used as the cushioning elastic element of the tonearm.

[0036] As can be seen from the above, the beneficial effects of this utility model are: by adopting its mechanism, it can effectively solve the problem in the prior art where the turntable recognition head of a record player is prone to up-and-down vibration, resulting in unstable contact between the stylus and the record and producing noise. By using this product structure, the fixing part fixes the tonearm return member 3 to the phono head 5, and the tonearm buffer elastic member 4 is set between the phono head mechanism frame 1 and the tonearm return member 3, which can fix the relative position between the phono head 5, the phono head mechanism frame 1 and the tonearm return member 3, effectively reducing the possibility of axial movement of the phono head 5 on the phono head mechanism frame 1, improving the stability of the phono head 2 during operation, thereby ensuring the stability of the contact between the stylus and the record, reducing the possibility of noise from the device, ensuring the normal use of the record player, and improving the user experience.
