[0002] In the related art, when the record player plays a vinyl record, it is necessary to manually lift and rotate the tonearm so that the stylus on the tonearm moves to the top of the vinyl record. When the record player finishes playing the vinyl record, it is also necessary to manually lift and rotate the tonearm so that the stylus on the tonearm leaves the vinyl record and returns to its initial position. In addition, this type of record player cannot automatically complete fast forward and fast rewind operations during playback, so the degree of automation is low and the user experience is poor. Summary of the invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention provides a record player drive module, which can realize automatic lifting and rotation of the tone arm and improve the automation level of the record player.

[0004] The present invention also provides a record player having the record player driving module, and a control method applied to the record player.

[0005] According to a first aspect of the present invention, the record player drive module comprises a tonearm drive module and a mounting frame, wherein the mounting frame has an inner side facing the inside of the record player and an outer side facing the outside of the record player, and the tonearm drive module comprises:

[0006] The tonearm assembly includes a connecting shaft and a tonearm, wherein the connecting shaft is passed through a mounting frame, the connecting shaft has a first end located inside the mounting frame and a second end located outside the mounting frame, the tonearm is rotatably connected to the second end of the connecting shaft, and a power receiving disk is provided at the first end;

[0007] The first driving mechanism is slidably connected to the inner side of the mounting frame along the axial direction of the connecting shaft, and includes a first driver and a power output disk; the first driver is drivingly connected to the power output disk and is used to drive the power output disk to rotate; the power output disk is coaxial with the connecting shaft and opposite to the power receiving disk;

[0008] The lifting frame is slidably disposed on the mounting frame 10 along the axial direction of the connecting shaft and abuts against a side of the tonearm close to the mounting frame;

[0009] The second driving mechanism includes a second driver, a first output member and a second output member, wherein the first output member is connected to the first driving mechanism, and the second output member is connected to the lifting frame; the second driver is drivingly connected to the first output member and the second output member; wherein,

[0010] When the second driver runs in the forward direction, it can drive the first output member to drive the first driving mechanism to slide so that the power output disk abuts against the power receiving disk, and can synchronously drive the second output member to drive the lifting frame to slide so that the tonearm is rotated and lifted to the side away from the mounting frame; when the second driver runs in the reverse direction, it can drive the first output member to drive the first driving mechanism to slide so that the power output disk is away from the power receiving disk, and can synchronously drive the second output member to drive the lifting frame to slide so that the tonearm is rotated and lowered to the side close to the mounting frame.

[0056] The following is the attached Figure 1 To Attachment Fig.17 , describing the record player drive module of the first aspect of the embodiment of the present invention.

[0057] Reference Figures 1 to 4 The record player drive module of this embodiment includes a tonearm drive module and a mounting bracket 10. The mounting bracket 10 has an inner side facing the inside of the record player and an outer side facing the outside of the record player. The tonearm drive module includes a tonearm assembly 40, a first drive mechanism 50, a lifting frame 60 and a second drive mechanism 70.

[0058] Reference Figures 1 to 5 The tonearm assembly 40 includes a connecting shaft 42 and a tonearm 41. The connecting shaft 42 passes through the mounting frame 10. The connecting shaft 42 has a first end 421 located on the inner side of the mounting frame 10 and a second end 422 located on the outer side of the mounting frame 10, wherein the first end 421 is provided with a power receiving disk 441; and one end of the tonearm 41 is rotatably connected to the second end 422 of the connecting shaft 42, and the other end of the tonearm 41 away from the connecting shaft 42 is provided with a stylus 411.

[0059] Reference Figures 4 to 8 The first driving mechanism 50 is slidably connected to the inner side of the mounting frame 10 along the axial direction of the connecting shaft 42, and includes a first driver 520 and a power output disk 540; the first driver 520 is transmission-connected to the power output disk 540, and is used to drive the power output disk 540 to rotate; the power output disk 540 is coaxial with the connecting shaft 42, and is opposite to the power receiving disk 441. When the power output disk 540 abuts against the power receiving disk 441, it can transmit power and motion to the power receiving disk 441, thereby driving the entire tonearm assembly 40 to rotate around the axis of the connecting shaft 42, and when driving the tonearm assembly 40 to rotate forward, it can make the tonearm 41 move away from the initial position and turn to the playback end position close to the center of the record, or drive the tonearm assembly 40 to rotate in the opposite direction, so that the tonearm 41 moves away from the playback end position of the center of the record and turns to the initial position.

[0060] Reference Figure 1 and Figure 5 The lifting frame 60 is slidably disposed in the mounting frame 10 along the axial direction of the connecting shaft 42, and abuts against the side of the tonearm 41 close to the mounting frame 10; Figure 5 and Figure 6The second driving mechanism 70 includes a second driver 71, a first output member 72 and a second output member 73, the first output member 72 is connected to the first driving mechanism 50, and the second output member 73 is connected to the lifting frame 60; the second driver 71 is in transmission connection with the first output member 72 and the second output member 73; wherein, when the second driver 71 runs in the forward direction, it can drive the first output member 72 to drive the first driving mechanism 50 to slide so that the power output disk 540 abuts against the power receiving disk 441, and can synchronously drive the second output member 73 to drive the lifting frame 60 to slide so that the tonearm 41 is rotated and lifted to the side away from the mounting frame 10; when the second driver 71 runs in the reverse direction, it can drive the first output member 72 to drive the first driving mechanism 50 to slide so that the power output disk 540 is away from the power receiving disk 441, and can synchronously drive the second output member 73 to drive the lifting frame 60 to slide so that the tonearm 41 is rotated and lowered to the side close to the mounting frame 10.

[0061] It should be understood that, since the record player drive module of the present embodiment is provided with the first drive mechanism 50 and the second drive mechanism 70, when it is necessary to move the tonearm 41 from the initial position to the start position of playback, the second drive 71 can be first operated in the forward direction, thereby driving the first output member 72 to drive the first drive mechanism 50 to slide so that the power output disk 540 abuts against the power receiving disk 441, and synchronously driving the second output member 73 to drive the lifting frame 60 to slide so that the tonearm 41 is rotated and lifted to the side away from the mounting frame 10. At this time, the height of the stylus 411 on the tonearm 41 will be higher than the upper surface of the record, and then the first drive 520 is operated in the forward direction to drive the power output disk 540 to rotate forward, thereby driving the power receiving disk 441 to And the entire tonearm assembly 40 rotates in the forward direction around the axis of the connecting shaft 42, so that the tonearm 41 carries the stylus 411 and moves toward the center of the record. When the stylus 411 moves to above the playback start position at the edge of the record, the second driver 71 is operated in the reverse direction, so that the tonearm 41 can be rotated toward the side close to the mounting bracket 10, that is, the tonearm 41 is rotated and lowered, so that the stylus 411 contacts and cooperates with the groove on the record. At the same time, the power output disk 540 will also move away from the power receiving disk 441, that is, the tonearm assembly 40 is separated from the first drive mechanism 50, so that the tonearm 41 and the stylus 411 can rotate driven by the groove on the record, so as to move to the playback end position in the center of the record as the record rotates.

[0062] Similarly, when it is necessary to move the tonearm 41 from the playback end position to the initial position, the second driver 71 can be operated in the forward direction first to drive the power output disk 540 to slide and abut the power receiving disk 441, and synchronously drive the tonearm 41 to rotate toward the side away from the mounting bracket 10, that is, drive the tonearm 41 to complete the rotation and lifting so that the stylus 411 is away from the record, and then the first driver 520 is operated in the reverse direction to drive the tonearm 41 to rotate in the reverse direction around the axis of the connecting shaft 42 and return to the top of the initial position, and then the second driver 71 is operated in the reverse direction to drive the power output disk 540 to slide and disengage from the power receiving disk 441, and synchronously drive the tonearm 41 to rotate toward the side close to the mounting bracket 10, that is, drive the tonearm 41 to complete the rotation and descent so that the tonearm 41 returns to the initial position.

[0063] Similarly, when automatic fast forward playback is required, the second driver 71 can be first operated in the forward direction to drive the power output disk 540 to slide and abut the power receiving disk 441, and synchronously drive the tonearm 41 to rotate toward the side away from the mounting bracket 10, that is, drive the tonearm 41 to complete the rotation and lifting so that the stylus 411 is away from the record, and then the first driver 520 is operated in the forward direction to drive the tonearm 41 to rotate forward around the axis of the connecting shaft 42, and move the stylus 411 on the tonearm 41 to above the position on the record where the playback is desired, and then the second driver 71 is operated in the reverse direction to drive the power output disk 540 to slide and disengage from the power receiving disk 441, and synchronously drive the tonearm 41 to rotate toward the side close to the mounting bracket 10, that is, drive the tonearm 41 to complete the rotation and descent, so that the stylus 411 abuts against the position on the record where the playback is desired, thereby completing automatic fast forward playback.

[0064] Similarly, when automatic fast-rewind playback is required, the second driver 71 can be first operated in the forward direction to drive the power output disk 540 to slide and abut the power receiving disk 441, and synchronously drive the tonearm 41 to rotate toward the side away from the mounting bracket 10, that is, drive the tonearm 41 to complete the rotation and lifting so that the stylus 411 is away from the record, and then the first driver 520 is operated in the reverse direction to drive the tonearm 41 to rotate in the reverse direction around the axis of the connecting shaft 42, and move the stylus 411 on the tonearm 41 to above the position on the record where the playback is desired, and then the second driver 71 is operated in the reverse direction to drive the power output disk 540 to slide and disengage from the power receiving disk 441, and synchronously drive the tonearm 41 to rotate toward the side close to the mounting bracket 10, that is, drive the tonearm 41 to complete the rotation and descent, so that the stylus 411 abuts against the position on the record where the playback is desired, thereby completing automatic fast-rewind playback.

[0065] From the above description, it can be known that since the first driving mechanism 50 and the second driving mechanism 70 can respectively realize automatic rotation and lifting of the tonearm 41, with the help of the cooperation of the first driving mechanism 50 and the second driving mechanism 70, the tonearm 41 can be automatically moved from the initial position to the start position of playback on the record when playback starts, and the tonearm 41 can be automatically returned to the initial position from the end position of playback on the record after playback ends. The record player can also automatically realize fast forward playback and fast reverse playback. Therefore, by adopting the record player drive module of this embodiment, the automation level of the record player can be improved and the user experience of the record player can be improved.

[0066] It is understandable that in some embodiments, the record player drive module also includes a turntable drive module, and the turntable drive module is arranged on the mounting frame 10 to ensure the installation position accuracy between the turntable drive module and the tonearm drive module. Among them, the turntable drive mechanism includes a turntable and a third drive mechanism for driving the turntable to rotate. The turntable is used to install the record and can drive the record to rotate under the drive of the third drive mechanism. It should be understood that since the turntable drive module is not an improvement point of the present invention, the turntable drive module is not shown in the drawings of the specification. The detailed structure of the turntable drive module can refer to the prior art and will not be described in detail here.

[0067] It is understandable that in order to better transmit power and motion to the power receiving disk 441, in some embodiments, reference is made to Figure 3 , Figure 5 and Figure 8 A first tooth surface is provided on the side of the power output disk 540 facing the power receiving disk 441, and a second tooth surface for meshing with the first tooth surface is provided on the side of the power receiving disk 441 facing the power output disk 540, so that when the power output disk 540 abuts against the power receiving disk 441, relative sliding between the power output disk 540 and the power receiving disk 441 can be avoided by means of the meshing between the first tooth surface and the second tooth surface.

[0068] And, refer to Figure 3 and Figure 8In one embodiment, specifically, a plurality of evenly and densely arranged first convex teeth 542 are provided on the first tooth surface, and the first convex teeth 542 are in a pointed cone shape. A plurality of evenly and densely arranged second convex teeth 443 are provided on the second tooth surface, and the second convex teeth 443 are also in a pointed cone shape. The second convex teeth 443 can be embedded between two adjacent first convex teeth 542, and the first convex teeth 542 can be embedded between two adjacent second convex teeth 443, so that the first tooth surface and the second tooth surface can be meshed with each other. Moreover, since the first convex teeth 542 and the second convex teeth 443 are both in a pointed cone shape, even when the power output disc 540 slides toward the power receiving disc 441, the first convex teeth 542 abut against the second convex teeth 443. With the help of the self-guiding property of the first protruding tooth 542 and the second protruding tooth 443, the power receiving disk 441 can rotate and adjust itself under the push of the first protruding tooth 542, so that the first protruding tooth 542 can be smoothly embedded between the two adjacent second protruding teeth 443; moreover, by arranging the first protruding teeth 542 and the second protruding teeth 443 in a dense and uniform arrangement on the power output disk 540 and the power receiving disk 441, respectively, the diameter size of the first protruding teeth 542 and the second protruding teeth 443 can be reduced, thereby reducing the angle value of the power receiving disk 441 that needs to rotate and adjust itself when the first protruding tooth 542 and the second protruding tooth 443 are engaged, thereby improving the minimum fast-forward amount accuracy that can be achieved in a single fast-forward during fast-forward playback.

[0073] It should be understood that, in order to achieve the sliding of the first driving mechanism 50 on the mounting frame 10, in one embodiment, referring to Figures 5 to 8 The record player drive module also includes a connecting frame 20 connected to the inner side of the mounting frame 10, the first drive mechanism 50 is located between the connecting frame 20 and the mounting frame 10, and a plurality of first guide rod portions 518 are provided on the side of the lower shell 516 facing the connecting frame 20, the first guide rod portions 518 are arranged parallel to the axial direction of the connecting shaft 42, and the connecting frame 20 is provided with a plurality of first guide holes 21 for one-to-one matching with the first guide rod portions 518, so that the first drive mechanism 50 can slide on the mounting frame 10 along the axial direction of the connecting shaft 42; and, in order to ensure that the first abutting structure 513 and the first lifting gear can always maintain abutment, the record player drive module also includes a plurality of compression springs 30, the plurality of compression springs 30 are one-to-one correspondingly sleeved on the first guide rod portions 518, and the two ends of the compression springs 30 are respectively abutted against the lower shell 516 and the connecting frame 20.

[0074] It is understood that in one embodiment, referring to Figures 5 to 8The connecting shaft 42 is passed through the first lifting gear and the first driving mechanism 50, and the first lifting gear is coaxially arranged with the connecting shaft 42, wherein the upper shell 511 is provided with an avoidance hole 512 for allowing the connecting shaft 42 to penetrate therein, and the first abutment structure 513 is an arcuate convex rib arranged on the side of the upper shell 511 facing the first lifting gear and arranged around the avoidance hole 512.

[0075] It is understood that, similarly, in order to drive the lifting frame 60 to slide on the mounting frame 10, thereby raising or lowering the tonearm 41, in one embodiment, referring to Figure 5 , Figure 6 , Fig.10 and Fig.11A second abutment structure 61 is provided on the side of the lifting frame 60 facing the second output member 73. The first output member 72 is a second lifting gear. The second lifting gear has a second abutment plane 731, a second abutment slope 732 and a third abutment plane 733 for abutting with the first abutment structure 513. The second abutment slope 732 is spirally arranged around the axis of the second lifting gear, and the second abutment plane 731 and the third abutment plane 733 are respectively connected at both ends. The second abutment plane 731 and the third abutment plane 733 are perpendicular to the axis of the second lifting gear; the axis of the second lifting gear is parallel to the axis of the connecting shaft 42. It should be understood that when the second abutment structure 61 abuts against the second abutment plane 731, the lifting frame 60 is in a higher position (that is, the lifting frame 60 is in a position where the distance from one end of the outer side of the mounting frame 10 to the outer side of the mounting frame 10 is larger), and when the second abutment structure 61 abuts against the third abutment plane 733, the lifting frame 60 is in a lower position (that is, the distance from one end of the outer side of the mounting frame 10 to the outer side of the mounting frame 10 is smaller); and in the process of the second driver 71 running forward to drive the second lifting gear to rotate forward, the third abutment plane 733, the second abutment slope 732 and the second abutment plane 731 can be rotated in a forward direction. The second abutment structure 61 abuts against the second abutment structure 61 for the second time, thereby enabling the lifting frame 60 to slide forward, and then the lifting frame 60 can slide to a higher position to lift the tonearm 41; and when the second driver 71 runs in reverse to drive the second lifting gear to rotate in the opposite direction, the second abutment plane 731, the second abutment slope 732 and the third abutment plane 733 will abut against the second abutment structure 61 in sequence, thereby enabling the lifting frame 60 to slide in the opposite direction, and then the lifting frame 60 can slide to a lower position, so that the tonearm 41 follows the lifting frame 60 to descend (the tonearm 41 can remain in abutment with the lifting frame 60 under the action of gravity or elastic force during the descent).

[0076] It should be understood that, in order to achieve the sliding of the lifting frame 60 on the mounting frame 10, in one embodiment, referring to Fig.10The lifting frame 60 includes an arc-shaped support platform 62, a lifting seat 63, a second guide rod portion 64 and a second abutment structure 61 arranged on the side of the lifting seat 63 away from the arc-shaped support platform 62, wherein the arc-shaped support platform 62 and the lifting seat 63 are located on the outside of the mounting frame 10, and the arc-shaped support platform 62 is used to abut the tonearm 41, and the second abutment structure 61 is a top rod portion, and the top rod portion and the second guide rod portion 64 are both parallel to the axis of the connecting shaft 42, and the mounting frame 10 is provided with a second guide hole (not shown in the accompanying drawings) and a third guide hole 11 respectively cooperating with the second guide rod portion 64 and the top rod portion, so that the lifting frame 60 can slide on the mounting frame 10 along the axial direction of the connecting shaft 42; and the end of the top rod portion away from the lifting seat 63 is used to abut with the second lifting gear, so that the second lifting gear cooperates with the top rod portion to drive the lifting frame 60 and the tonearm 41 to rise and fall together.

[0077] It is understood that in order to transmit the power and movement of the first driver 520 to the first lifting gear and the second lifting gear respectively, in some embodiments, reference is made to Figure 6 The second driving mechanism 70 includes a transmission gear set 74, and the second driver 71 is a second motor. The second motor is connected to the first lifting gear through the transmission gear set 74. It should be understood that the transmission gear set 74 includes at least a pair of gears meshing with each other, and the input gear in the transmission gear set 74 is arranged on the output shaft of the second motor, and the output gear in the transmission gear set 74 is meshed with the first lifting gear. Therefore, the rotation and torque of the second motor can be transmitted to the first lifting gear through the transmission gear set 74, thereby driving the first transmission gear to rotate, and then driving the first driving mechanism 50 to slide; and the first lifting gear is meshed with the second lifting gear, so that the power can also be transmitted to the second lifting gear with the help of the first lifting gear, thereby driving the second transmission gear to rotate, and then driving the lifting frame 60 to slide and rise and fall. It should be understood that by setting the second lifting gear to mesh with the first lifting gear, it is also convenient to calculate and design the relationship ratio between the center angle corresponding to the first abutment bevel 721 and the center angle corresponding to the second abutment bevel 732 more quickly through the transmission ratio between the second lifting gear and the first lifting gear, thereby ensuring that when the power output disk 540 abuts the power receiving disk 441, the tonearm 41 has also been lifted into place, thereby preventing the stylus 411 from scratching the record when the first drive mechanism 50 subsequently drives the tonearm 41 to rotate.

[0078] It is understandable that, referring to Figure 6In order to facilitate the control of the coordinated cooperation between the first driving mechanism 50 and the second driving mechanism 70, in some embodiments, the record player drive module also includes a control module (not shown in the drawings) and a lifting-in-place detection device 81, wherein the control module is electrically connected to the lifting-in-place detection device 81, the first driver 520 and the second driver 71, and an abutment portion 519 is provided on the first driving mechanism 50, and the lifting-in-place detection device 81 is opposite to the abutment portion 519, and when the power output disk 540 abuts against the power receiving disk 441, the abutment portion 519 enters the detection range of the lifting-in-place detection device 81, and the control module can control the second driver 71 according to the detection signal of the lifting-in-place detection device 81. It should be understood that, through the above structure, when the tonearm 41 needs to be lifted, the control module will control the second driver 71 to operate in the forward direction to drive the first drive mechanism 50 to slide in the direction close to the power receiving disk 441, and synchronously control the lifting frame 60 to slide to a higher position, and when the lifting-in-place detection device 81 detects the abutment 519, it means that the power output disk 540 is abutting against the power receiving disk 441, and the lifting frame 60 drives the tonearm 41 to rotate and lift into place, and the lifting-in-place detection device 81 will be able to send a corresponding detection signal to the control module. The control module will control the second driver 71 to stop running and control the first driver 520 to start according to the detection signal generated by the lifting-in-place detection device 81 at this time. and when the tonearm 41 needs to be lowered, the control module will control the second driver 71 to operate in the reverse direction to drive the first drive mechanism 50 to slide in the direction away from the power receiving disk 441, and synchronously control the lifting frame 60 to slide to a lower position, and when the lifting-in-place detection device 81 detects that the abutment portion 519 is out of its detection range, it will be able to send a corresponding detection signal to the control module. The control module will control the second driver 71 to stop running after a delay of a preset time according to the detection signal generated by the lifting-in-place detection device 81 at this time, so that the tonearm 41 can be lowered a sufficient distance from the lifted position, so that the stylus 411 on the tonearm 41 can abut against the record, or the tonearm 41 can be lowered back to its initial position.

[0079] It is understood that in one embodiment, referring to Figures 6 to 8 Specifically, the lifting-in-place detection device 81 is a detection switch, and the abutment portion 519 is arranged on the upper shell 511 and is opposite to the detection switch, so that when the abutment portion 519 enters the detection range of the detection switch, it will abut against the detection switch to make the detection switch turned on, and when the abutment portion 519 leaves the detection range of the detection switch, the abutment portion 519 is separated from the detection switch and can make the detection switch disconnected.

[0080] It should be understood that in some other embodiments, the abutment portion 519 may also be selectively provided on the lifting frame 60. For example, the abutment portion 519 may be provided on the second guide rod portion 64, and the detection switch may be provided on the mounting frame 10 and located between the abutment portion 519 and the mounting frame 10. Thus, when the lifting frame 60 slides to a higher position, the abutment portion 519 will be able to abut against the detection switch to make the detection switch turned on. When the lifting frame 60 slides to a lower position, the abutment portion 519 is separated from the detection switch and is able to make the detection switch turned off.

[0081] It is understood that in some of these embodiments, reference Fig.12 The tonearm driving module also includes an initial position sensor 82 and an end position sensor 83, which are arranged at intervals along the circumference of the connecting shaft 42, and a first sensing portion 451 is arranged on the connecting shaft 42, and the connecting shaft 42 can drive the first sensing portion 451 to rotate into the sensing area of ​​the initial position sensor 82 and the end position sensor 83; the control module is electrically connected to the initial position sensor 82 and the end position sensor 83, and can control the first driver 520 and the second driver 71 according to the sensing signals of the initial position sensor 82 and the end position sensor 83.

[0082] It should be understood that when the first sensing portion 451 rotates in the opposite direction along with the connecting shaft 42 to the sensing area of ​​the initial position sensor 82, the tonearm 41 also rotates in the opposite direction to above the initial position. At this time, the control module will be able to control the first driver 520 to stop running according to the sensing signal of the initial position sensor 82, and then control the second driver 71 to run in the opposite direction, so that the tonearm 41 drops to the initial position; and when the first sensing portion 451 rotates in the opposite direction along with the connecting shaft 42 to the sensing area of ​​the end position sensor 83, the tonearm 41 also rotates forward to the end position of the record. At this time, the control module will be able to control the first driver 520 to stop running according to the sensing signal of the end position sensor 83, and then control the second driver 71 to run forward, so that the tonearm 41 is lifted to separate from the record, and then control the first driver 520 and the second driver 71 to cooperate to return the tonearm 41 to the initial position.

[0083] It is understandable that in some embodiments, common records are usually available in two sizes, 17" and 30", and the playback start positions of the edges of the records of these two sizes are different. In order to enable the stylus 411 on the tonearm 41 to automatically reach the playback start position of the records of the two different sizes, the stylus 411 on the tonearm 41 is shown in FIG. Fig.12The tonearm driving module also includes a first edge position sensor 84 and a second edge position sensor 85, which are also arranged at intervals along the circumference of the connecting shaft 42. A second sensing portion 452 is provided on the connecting shaft 42, and the connecting shaft 42 can drive the second sensing portion 452 to rotate into the sensing area of ​​the first edge position sensor 84 and the first edge position sensor 84; the control module is electrically connected to the first edge position sensor 84 and the first edge position sensor 84, and can control the first driver 520 and the second driver 71 according to the sensing signals of the first edge position sensor 84 and the first edge position sensor 84.

[0084] It should be understood that if the record is a 30" record, when the playback starts and the tonearm 41 turns toward the record, when the second sensing portion 452 rotates forward along with the connecting shaft 42 to the sensing area of ​​the first edge position sensor 84, the tonearm 41 also correspondingly rotates forward to above the playback start position of the 30" record edge. At this time, the control module will be able to control the first driver 520 to stop running based on the sensing signal of the first edge position sensor 84, and will then control the second driver 71 to run in reverse, so that the tonearm 41 drops and the stylus 411 abuts against the playback start position of the 30" record edge.

[0085] Similarly, if the record is a 17” record, when the playback starts and the tonearm 41 turns toward the record, when the second sensing portion 452 rotates forwardly along with the connecting shaft 42 to the sensing area of ​​the second edge position sensor 85, the tonearm 41 also correspondingly rotates forwardly to above the playback start position of the edge of the 17” record. At this time, the control module will be able to control the first driver 520 to stop running based on the sensing signal of the second edge position sensor 85, and will then control the second driver 71 to run in reverse, so that the tonearm 41 drops and the stylus 411 abuts against the playback start position of the edge of the 17” record.

[0086] It is understood that in one embodiment, referring to Fig.12 The initial position sensor 82, the end position sensor 83, the first edge position sensor 84 and the second edge position sensor 85 are all photoelectric sensors. The photoelectric sensor includes a transmitting part and a receiving part that are spaced apart, and the sensing area of ​​the photoelectric sensor is located between the transmitting part and the receiving part, so that when the first sensing part 451 or the second sensing part 452 rotates and enters between the transmitting part and the receiving part of the corresponding photoelectric sensor, a corresponding sensing signal will be generated.

[0087] It should be understood that in some other embodiments, the initial position sensor 82 , the end position sensor 83 , the first edge position sensor 84 and the second edge position sensor 85 may also be configured as detection switches.

The square shaft portion 432 is adjacent to the threaded portion 431, and the stop portion 433 protrudes from the shaft body 430 along the circumferential direction and is located on the side of the square shaft portion 432 away from the threaded portion 431; a square hole 444 is provided at the center of the power receiving member 440, and the shaft body 430 is penetrated through the square hole 444, and the square shaft portion 432 cooperates with the square hole 444 to receive the rotational power transmitted by the power receiving member 440; the shaft body 430 cooperates with the power receiving member 440 through the stop portion 433 The force receiving member 440 abuts to limit the power receiving member 440 from sliding on the shaft body 430 toward the side close to the first driving mechanism 50; the detection member 450 is sleeved on the shaft body 430 and is located on the side of the power receiving member 440 away from the first driving mechanism 50, and the threaded locking member 490 is used to be threadedly connected to the threaded portion 431, and can then cooperate with the limiting portion 433 to press and fix the power receiving member 440 and the detection member 450 on the shaft body 430.

[0090] It should be understood that in some of the embodiments, the detection member 450 is rotatably and adjustably connected to the power receiving member 440, so that when the threaded locking member 490 is loosened, the angle between the detection member 450 and the tonearm 41 can be adjusted, so that when the first sensing portion 451 or the second sensing portion 452 on the detection member 450 enters the sensing range of the corresponding sensor, the tonearm 41 can be located at the corresponding position. For example, when the first sensing portion 451 enters the sensing range of the initial position sensor 82, the tonearm 41 can be located just at the initial position, or the tonearm 41 can be located just above the initial position.

[0091] It should be understood that, in order to realize the rotatable adjustment of the detection member 450 on the power receiving member 440, in one embodiment, referring to Figure 5 , Figures 13 to 18 The power receiving member 440 is provided with an annular groove 445 on the side facing away from the first driving mechanism 50, and the detection member 450 is provided with an annular platform portion 453 embedded in the annular groove 445, so that the detection member 450 can be rotatably connected to the power receiving member 440 by means of the cooperation between the annular platform portion 453 and the annular groove 445.

[0095] The following describes a control method for a record player in some embodiments of the third aspect of the present invention. It should be understood that, in some embodiments, the record player also includes a plurality of buttons such as a start button, a stop button, a fast forward button, a fast rewind button, and the like, and the start button, the stop button, the fast forward button, the fast rewind button, and the like are all electrically connected to the control module; correspondingly, the control method for the record player includes a plurality of control processes such as a playback control process, a playback stop control process, a fast forward control process, and a fast rewind control process, and the corresponding control process can be started by pressing the corresponding button.

[0096] For example, in some of the embodiments, the playback control process includes but is not limited to the following steps S110 to S180.

[0097] S110, when the control module detects that the start key is pressed, the second driver 71 is controlled to run forward.

[0098] It should be understood that in step S110, the second driver 71 runs forward to drive the first driving mechanism 50 to slide toward the power receiving plate 441, and simultaneously drives the lifting frame 60 to slide to gradually lift the tonearm 41 in the initial position.

[0099] S120, when the abutment portion 519 enters the detection range of the lifted-in-position detection device 81, the control module controls the second driver 71 to stop running according to the detection signal generated by the lifted-in-position detection device 81, and controls the first driver 520 to run forward to drive the tonearm 41 to rotate toward the center of the record.

[0100] It should be understood that in step S320, when the abutment portion 519 enters the detection range of the lifting-in-place detection device 81, it means that the tonearm 41 has completed the lifting and the power output disk 540 has abutted against the power receiving disk 441. At this time, the second driver 71 is controlled to stop running, and the first driver 520 is controlled to run in the forward direction, which can drive the power output disk 540 and the entire tonearm assembly 40 to rotate in the forward direction, thereby causing the tonearm 41 to rotate from the initial position to the center of the record.

[0101] S130, when the second sensing portion 452 enters the sensing area of ​​the first edge position sensor 84 or the second edge position sensor 85, the control module controls the first driver 520 to stop running and controls the second driver 71 to run in reverse according to the sensing signal generated by the first edge position sensor 84 or the second edge position sensor 85.

[0102] It should be understood that, with respect to the above-mentioned step S130, when the second sensing portion 452 enters the sensing area of ​​the first edge position sensor 84 or the second edge position sensor 85, it means that the tonearm 41 has carried the stylus 411 to the top of the start position of playback. At this time, the control module controls the first driver 520 to stop running, and controls the second driver 71 to run in reverse, so that the tonearm 41 and the stylus 411 can be gradually lowered.

[0103] S140 , when the contact portion 519 escapes from the detection range of the lifted-in-place detection device 81 , the control module controls the second driver 71 to stop running after a preset time according to the detection signal generated by the lifted-in-place detection device 81 .

[0104] It should be understood that, with respect to the above-mentioned step S140, when the abutment portion 519 escapes from the detection range of the lifting-in-place detection device 81, it indicates that the first drive mechanism 50 has begun to separate from the power receiving disk 441. At the same time, the lifting frame 60 is also synchronously driving the tonearm 41 to descend, and controlling the second driver 71 to stop running after a preset time can enable the lifting frame 60 to drive the tonearm 41 to descend a sufficient distance and enable the stylus 411 on the tonearm 41 to abut against the start position of playback on the record.

[0105] S150 , when the first sensing portion 451 enters the sensing area of ​​the end position sensor 83 , the control module controls the second driver 71 to run in the forward direction according to the sensing signal generated by the end position sensor 83 .

[0106] It should be understood that, regarding the above-mentioned step S150, as the record rotates during playback (achieved by controlling the operation of the turntable drive module), the stylus 411 and the tonearm 41 will also move toward the playback end position in the center of the record driven by the groove on the record, and the first sensing portion 451 will also enter the sensing area of ​​the end position sensor 83. At this time, controlling the second driver 71 to run in the forward direction can lift the tonearm 41 and detach the stylus 411 from the record.

[0107] S160, when the abutment portion 519 enters the detection range of the lifting-in-place detection device 81, the control module controls the second driver 71 to stop running according to the detection signal generated by the lifting-in-place detection device 81, and controls the first driver 520 to run in reverse to drive the tonearm 41 to turn to the initial position.

[0108] S170 , when the first sensing portion 451 enters the sensing area of ​​the initial position sensor 82 , the control module controls the first driver 520 to stop running and controls the second driver 71 to run in the reverse direction according to the sensing signal generated by the initial position sensor 82 .

[0109] It should be understood that, with respect to the above-mentioned step S170, when the first sensing portion 451 enters the sensing area of ​​the initial position sensor 82, it means that the tonearm 41 has rotated to above the initial position. At this time, controlling the first driver 520 to stop running and controlling the second driver 71 to run in reverse can enable the tonearm 41 to start to descend.

[0110] S180 , when the contact portion 519 escapes from the detection range of the lifted-in-place detection device 81 , the control module controls the second driver 71 to stop running after a preset time according to the detection signal generated by the lifted-in-place detection device 81 .

[0111] It should be understood that, with respect to the above-mentioned step S180, when the abutment portion 519 escapes from the detection range of the lifting-in-place detection device 81, it indicates that the first drive mechanism 50 has begun to separate from the power receiving disk 441. At the same time, the lifting frame 60 is also synchronously driving the tonearm 41 to descend, and controlling the second driver 71 to stop running after a preset time can enable the lifting frame 60 to drive the tonearm 41 to descend a sufficient distance and allow the tonearm 41 to descend and return to its initial position.

[0112] It should be understood that through the playback control process of this embodiment, the record player can automatically play when the play button is pressed and the tonearm 41 can be automatically reset to the initial position after the playback is completed to avoid damage to the record and the stylus 411. This not only improves the user experience, but also reduces the risk of damage to the record and the stylus 411.

[0113] It should be understood that, in some of the embodiments, the stop playback control process includes the following steps S210 to S240.

[0114] S210: When the control module detects that the stop button is pressed, the second driver 71 is controlled to run forward.

[0115] It should be understood that in step S210, the second driver 71 runs forward to drive the first driving mechanism 50 to slide toward the power receiving plate 441, and simultaneously drives the lifting frame 60 to slide so that the tonearm 41 is gradually lifted, and the stylus 411 is separated from the record.

[0116] S220, when the abutment portion 519 enters the detection range of the lifting-in-place detection device 81, the control module controls the second driver 71 to stop running according to the detection signal generated by the lifting-in-place detection device 81, and controls the first driver 520 to run in reverse to drive the tonearm 41 to turn to the initial position.

[0117] S230 , when the first sensing portion 451 enters the sensing area of ​​the initial position sensor 82 , the control module controls the first driver 520 to stop running and controls the second driver 71 to run in the reverse direction according to the sensing signal generated by the initial position sensor 82 .

[0118] S240 , when the contact portion 519 escapes from the detection range of the lifting-in-place detection device 81 , the control module controls the second driver 71 to stop running after a preset time according to the detection signal generated by the lifting-in-place detection device 81 .

[0119] It should be understood that, through the stop playback control process of this embodiment, the tonearm 41 can be automatically reset to the initial position when the stop button is pressed to stop playback.

[0120] It should be understood that, in some of the embodiments, the fast-forward control process includes the following steps S310 to S340.

[0121] S310: When the control module detects that the fast forward key is pressed, the control module controls the second driver 71 to run forward.

[0122] S320, when the abutment portion 519 enters the detection range of the lifted-in-place detection device 81, the control module controls the second driver 71 to stop running according to the detection signal generated by the lifted-in-place detection device 81, and controls the first driver 520 to run forward to drive the tonearm 41 to rotate toward the center of the record.

[0123] S330: When the control module detects that the fast forward key is released, it controls the first driver 520 to stop running and controls the second driver 71 to run in the reverse direction.

[0124] It should be understood that, with respect to the above-mentioned step S330, when the operator realizes that the tonearm 41 has moved to the position where he wants to play, he can release the fast forward key, so that when the control module detects that the fast forward key is released, it controls the first driver 520 to stop running, and controls the second driver 71 to run in reverse, thereby driving the tonearm 41 to descend so that the stylus 411 on the tonearm 41 is close to the record.

[0125] S340 , when the contact portion 519 leaves the detection range of the lifted-in-place detection device 81 , the control module controls the second driver 71 to stop running after a preset time according to the detection signal generated by the lifted-in-place detection device 81 .

[0126] It should be understood that, with respect to the above-mentioned step S340, when the abutment portion 519 disengages from the lifted-in-place detection device 81, it indicates that the first drive mechanism 50 has begun to disengage from the power receiving disk 441. At the same time, the lifting frame 60 is also synchronously driving the tonearm 41 to descend, and controlling the second driver 71 to stop running after a preset time can enable the tonearm 41 to descend a sufficient distance so that the stylus 411 on the tonearm 41 can ensure abutment against the record.

[0127] It should be understood that through the fast-forward control process of this embodiment, the record player can automatically fast-forward playback when the fast-forward button is pressed, so that the user can quickly reach the position he wants to play without damaging the record and the needle 411. This not only improves the user experience, but also reduces the risk of damage to the record and the needle 411.

[0128] It should be understood that, in some of the embodiments, the fast rewind control process includes the following steps S410 to S440.

[0129] S410: When the control module detects that the fast rewind key is pressed, the control module controls the second driver 71 to run forward.

[0130] S420, when the abutment portion 519 enters the detection range of the lifted-in-position detection device 81, the control module controls the second driver 71 to stop running according to the detection signal generated by the lifted-in-position detection device 81, and controls the first driver 520 to run in reverse to drive the tonearm 41 to rotate in a direction away from the center of the record.

[0131] S430: When the control module detects that the fast rewind key is released, the control module controls the first driver 520 to stop running and controls the second driver 71 to run in the reverse direction.

[0132] It should be understood that, with respect to the above-mentioned step S430, similarly, when the operator realizes that the tonearm 41 has moved to the position where he wants to play, he can release the fast rewind key, so that when the control module detects that the fast rewind key is released, it controls the first driver 520 to stop running, and controls the second driver 71 to run in reverse, thereby driving the tonearm 41 to descend so that the stylus 411 on the tonearm 41 is close to the record.

[0133] S440 , when the contact portion 519 leaves the detection range of the lifted-in-place detection device 81 , the control module controls the second driver 71 to stop running after a preset time according to the detection signal generated by the lifted-in-place detection device 81 .

[0134] It should be understood that through the fast rewind control process of this embodiment, the record player can automatically fast rewind playback when the fast rewind button is pressed, so that the user can return to the position he wants to play again without damaging the record and the needle 411. This not only improves the user experience, but also reduces the risk of damage to the record and the needle 411.

[0135] It should be understood that in some of the embodiments, the record player also includes a record specification selection button, so that the first edge position sensor 84 or the second edge position sensor 85 can be selected and enabled through the record specification selection button; for example, when the record is of 30" specification, the first edge position sensor 84 can be selected and enabled through the record specification selection button, and then after pressing the play button, in the above step S130, when the second sensing portion 452 enters the sensing area of ​​the first edge position sensor 84, the control module can control the first driver 520 to stop running and control the second driver 71 to run in reverse. When the record is of 17" specification, the second edge position sensor 85 can be selected and enabled through the record specification selection button, and then after pressing the play button, in the above step S130, when the second sensing portion 452 enters the sensing area of ​​the second edge position sensor 85, the control module can control the first driver 520 to stop running and control the second driver 71 to run in reverse.
