DETAILED DESCRIPTION

[0023] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. Now, in conjunction with the accompanying drawings, a preferred embodiment of the present utility model is described in detail.

[0024] like Figure 1 and Figure 2 As shown, an embodiment of the utility model provides a tonearm module 100, comprising: an adjustment base 110, and an integrated tonearm 120 rotatably connected to the adjustment base 110, an open receiving groove 122 is provided at the bottom of the tonearm 120, a stylus module 130 is provided at one end of the tonearm 120, and a counterweight block 140 is provided at the other end, a wire is connected to the stylus module 130, and the wire is arranged along the receiving groove 122.

[0025] Specifically, the integrated tonearm 120 rotatably connected to the adjustment base 110 simplifies the structure, reduces the parts that may fail, and improves the reliability and durability of the overall system. Moreover, the integrated tonearm 120 has a relatively high structural consistency and can be processed in batches through one-piece injection molding, which has a low cost and requires fewer parts to be connected and assembled, which is beneficial to improving the reliability of the connection and simplifying the connection form.

[0026] When assembling the tonearm module 100, it is only necessary to connect the tonearm 120 to the adjustment base 110, and respectively set the stylus module 130 and the counterweight 140 at both ends of the tonearm 120. The counterweight 140 is conducive to ensuring the stable cooperation between the stylus module 130 and the turntable, and ensuring the stability during use. When the stylus module 130 cooperates with the turntable, the audio information collected by the stylus module 130 needs to be transmitted through a wire. By providing an open receiving groove 122 at the bottom of the tonearm 120, when guiding and wiring the wire, the operation can be performed directly from the opening of the tonearm 120, which is conducive to reducing the difficulty of operation and improving the efficiency of operation.

[0027] The tonearm module 100 provided in the embodiment of the present application can rotate the tonearm 120 relative to the adjustment base 110 through the adjustment base 110 and the integrated tonearm 120 rotatably connected to the adjustment base 110, so that the stylus module 130 connected to one end of the tonearm 120 moves to the top of the turntable, or deviates from the turntable. A counterweight 140 is provided at the other end of the tonearm 120 to balance the force when the stylus module 130 cooperates with the turntable to ensure stability during cooperation. In addition, the integrated tonearm 120 itself has a low manufacturing cost, and the connection form is simple and convenient during the assembly process, which is conducive to simplifying the setting form, improving operation efficiency, and greatly reducing labor costs. And when wiring the wire connected to the stylus module 130 set on the tonearm 120, it can be directly operated through the opening of the receiving groove 122 provided at the bottom of the tonearm 120, avoiding the difficulty of threading due to the wire being too soft, which is conducive to reducing the difficulty of operation. In actual applications, since the opening is located at the bottom of the tonearm 120, the opening is blocked by the upper body of the tonearm 120 during use and is not easily affected by the external environment, which is conducive to ensuring stable operation during use. In summary, the above method can simplify the setting form, improve the convenience of assembly, thereby improving production efficiency and reducing production costs.

[0028] like Figure 2 and Figure 3 As shown, the tonearm 120 includes a counterweight section 124, an extension section 126 and a pickup section 128 which are connected in sequence, and a through hole 1262 is provided on the extension section 126 so that the rotating shaft 1264 passes through the through hole 1262 and is connected to the adjustment base 110, the counterweight block 140 is provided on the counterweight section 124, the stylus module 130 is provided on the pickup section 128, and the distance between the counterweight section 124 and the through hole 1262 is smaller than the distance between the pickup section 128 and the through hole 1262.

[0029] Specifically, by providing a through hole 1262 on the extension section 126, the rotating shaft 1264 passes through the through hole 1262 to connect with the tonearm 120, and the rotating shaft 1264 passes through the adjustment base 110 at the same time, so as to realize the rotation connection between the extension section 126 and the adjustment base 110. By setting the distance between the counterweight section 124 and the through hole 1262 to be smaller than the distance between the cartridge section 128 and the through hole 1262, the distance between the tonearm 120 and the cartridge section 128 is balanced, so as to avoid the warping of one end of the cartridge section 128 caused by the excessive distance between the counterweight section 124 and the through hole 1262, thereby ensuring the stable contact between the stylus module 130 and the turntable.

[0030] like Figure 3 As shown, the counterweight section 124 and the extension section 126 are on the same straight line, and there is a preset angle between the cartridge section 128 and the extension section 126 .

[0031] Specifically, by arranging the counterweight section 124 and the extension section 126 on the same straight line, it is helpful to simplify the arrangement of the tonearm 120 body, and by arranging a preset angle between the head section 128 and the extension section 126, the stylus module 130 arranged at the head section 128 can be better matched with the turntable. It can be understood that the bending direction of the head section 128 should be arranged in the direction where the turntable is located.

[0032] like Figure 2 and Figure 3 As shown, a first limiting portion 1242 is provided in the counterweight section 124 for limiting the counterweight block 140 .

[0033] It should be noted that the embodiment of the present application does not specifically limit the specific structural form of the first limiting portion 1242. For example, the first limiting portion 1242 can be Figure 3 The combination of multiple protrusions shown in the figure can limit and fix the counterweight 140. The first limiting portion 1242 can also be in the form of a convex column or a convex strip. When the counterweight 140 and the first limiting portion 1242 are matched and limited, glue bonding, hot melt connection, interference fit and the like can be used. The first limiting portion 1242 can also be used as a connecting seat and used in conjunction with fasteners such as screws to limit the counterweight 140. Among them, the counterweight 140 needs to be in the receiving groove 122 corresponding to the counterweight section 124 and cannot protrude from the tonearm 120 to ensure the overall consistency.

[0034] Please continue to refer to Figure 2 and Figure 3 A second limiting portion 1282 is provided in the pickup section 128 for limiting the stylus module 130 .

[0035] It should be noted that the embodiment of the present application does not specifically limit the specific structural form of the second limiting portion 1282. For example, the first limiting portion 1242 can be Figure 3 The relatively arranged limiting blocks shown in the figure play a role in limiting and fixing the stylus module 130. When the stylus module 130 and the second limiting portion 1282 are matched and limited, glue bonding, auxiliary fixing by fasteners, etc. can be adopted. Among them, a countersunk hole can be provided on the top of the tonearm 120, and a screw is provided at the countersunk hole to connect with the stylus module 130, so as to ensure the stable connection between the stylus module 130 and the head section 128, avoid loosening and dislocation, and ensure stability during use.

[0036] like Figure 3As shown, a handle 129 is also integrally formed on the head section 128. With the above form, when the stylus module 130 is placed above the turntable, the position of the tonearm 120 can be moved by the handle 129, and the whole process is simple and convenient. In addition, the handle 129 is integrally formed with the head section 128, and no further connection is required, which is conducive to reducing the complexity of assembly.

[0037] In an optional embodiment of the present application, the tonearm 120 is made of ABS plastic. ABS plastic is a raw material that is easily available, has good comprehensive properties, and is cheap. During injection molding, it exhibits good fluidity, so that it has good properties of thermoplastic molding, which is conducive to improving the yield rate of processing, is not easy to deform during use, and is conducive to ensuring stability during use.

[0038] like Figure 1 As shown, the adjustment base 110 includes a mounting base 112 and a steering base 114 rotatably connected to the mounting base 112 , the tonearm 120 is rotatably connected to the steering base 114 , and the rotation plane where the tonearm 120 is located is perpendicular to the rotation plane where the steering base 114 is located.

[0039] Specifically, the mounting base 112 is used to connect with the base plate 220, and can rotate in the horizontal direction between the mounting base 112 and the base, so that the tone arm 120 can move toward or away from the turntable. In addition, the tone arm 120 can rotate in the vertical direction with the turning base 114, so that the tone arm 120 can be raised or lowered, so that the stylus module 130 connected to the tone arm 120 can be used in conjunction with the turntable.

[0040] In an optional embodiment of the present application, a cover plate is further provided on the tonearm 120, and the cover plate is detachably connected to the receiving groove 122. Specifically, the cover plate is provided at the opening of the receiving groove 122 to shield the receiving groove 122 and prevent the wires provided in the receiving groove 122 from being exposed, which is conducive to ensuring stability during use and reducing the influence of the external environment. The cover plate and the receiving groove 122 can be connected in the form of a snap connection or a magnetic connection to achieve the required detachable connection.

[0041] like Figure 4 As shown, the utility model also discloses a vinyl record device 200, including a chassis 210, a base plate 220 disposed on the chassis 210, and a tonearm module 100 as described above, wherein a turntable module 230 is also disposed on the base plate 220, the turntable module 230 is disposed on a driving module and a turntable on the base plate 220, the turntable is placed on the turntable, and the tonearm module 100 is located on one side of the turntable module 230. The vinyl record device 200 includes the same structure and beneficial effects as the tonearm module 100 in the aforementioned embodiment. The structure and beneficial effects of the tonearm module 100 have been described in detail in the aforementioned embodiment, and will not be repeated here.

[0042] It should be understood that the above embodiments are only used to illustrate the technical solutions of the present utility model rather than to limit it. For those skilled in the art, the technical solutions described in the above embodiments can be modified, or some of the technical features therein can be replaced by equivalents; and all these modifications and replacements should fall within the scope of protection of the claims attached to the present utility model.
