[0028] 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.
[0029] The utility model embodiment provides an integrated record player 1000, such as Figure 1 As shown, the integrated record player 1000 includes a mounting seat 100, a cartridge 300, a turntable mechanism 200, a shock absorber 400 and a speaker 500. The cartridge 300 and the turntable mechanism 200 are both mounted on the mounting seat 100. The turntable mechanism 200 is used to drive the record to rotate, and the cartridge 300 is used to cooperate with the turntable mechanism 200 to obtain the audio information of the record. One end of the shock absorber 400 is connected to the mounting seat 100, and the other end is connected to the speaker 500, so that the speaker 500 is layered and spaced at the bottom of the mounting seat 100, and the speaker 500 is electrically connected to the cartridge 300, so that the speaker 500 can play the audio information obtained by the cartridge 300.
[0030] Firstly, the speaker 500 of the present embodiment is separated from the mounting base 100. Compared with the prior art, the vibration generated when the speaker 510 in the speaker 500 of the present embodiment makes sound is not easily transmitted to the mounting base 100. Therefore, the turntable mechanism 200 and the cartridge 300 installed on the mounting base 100 will be more stable when working, thereby avoiding distortion of the sound played by the speaker 500, as well as avoiding noise and humming, thereby improving the user experience.
[0031] Secondly, the speaker 500 of the present embodiment is connected to the mounting base 100 via the shock absorber 400, so the vibration transmitted from the speaker 500 to the mounting base 100 will be weakened by the shock absorber 400, thereby further preventing the vibration generated when the speaker 510 in the speaker 500 makes a sound from being transmitted to the mounting base 100, further improving the stability of the turntable mechanism 200 and the cartridge 300 installed on the mounting base 100 during operation, further preventing the sound played by the speaker 500 from being distorted, and further avoiding the generation of noise and hum, providing an excellent user experience.
[0032] It should be noted that there are many types of shock absorbers 400, so this embodiment does not limit the specific structure of the shock absorber 400, and those skilled in the art can make adaptive selections, as long as the vibration transmitted from the speaker 500 to the mounting base 100 can be weakened to improve the stability of the turntable mechanism 200 and the cartridge 300 installed on the mounting base 100 during operation. A specific implementation of the shock absorber 400 is listed below for reference.
[0033] In a specific embodiment, the shock absorber 400 includes: a first connection seat 410, a second connection seat 420 and a spring 430. The first connection seat 410 and the second connection seat 420 are arranged opposite to each other, one of the first connection seat 410 and the second connection seat 420 is installed at the bottom of the mounting seat 100, and the other is installed at the top of the sound box 500. The first connection seat 410 is provided with an annular protrusion 411 on one side facing the second connection seat 420, and the annular protrusion 411 defines a receiving groove 412. The second connection seat 420 is provided with a groove 421 on one side facing the first connection seat 410, and the annular protrusion 411 is arranged to be received in the groove 421. One end of the spring 430 is received in the receiving groove 412, and the other end is received in the groove 421.
[0034] One end of the spring 430 of the present embodiment is accommodated in the accommodating groove 412 of the first connecting seat 410, and the other end is accommodated in the groove 421 of the second connecting seat 420. Because the annular protrusion 411 is partially accommodated in the groove 421, the user cannot directly see the spring 430 when observing the integrated record player 1000, which can provide a certain degree of protection for the spring 430.
[0035] In a specific embodiment, from the radial direction of the spring 430, the outer contour of the spring 430 is adapted to the contour of the receiving groove 412, so that the receiving groove 412 can be used to limit one end of the spring 430. The groove bottom of the groove 421 is also provided with a limiting protrusion 422, and the spring 430 is sleeved on the limiting protrusion 422, so that the two ends of the spring 430 can be constrained by the receiving groove 412 and the limiting protrusion 422 respectively, thereby avoiding the spring 430 from being offset during repeated expansion and contraction deformation, and then leaving the preset position, resulting in the weakening of the shock absorption effect of the shock absorber 400. Therefore, the implementation of this embodiment enables the shock absorber 400 to be used for a long time and stably.
[0036] In a specific embodiment, the shock absorber 400 also includes a guide rod 440 , and the second connecting seat 420 is provided with a through hole 423 opened along the gravity direction. One end of the guide rod 440 is fixed to the first connecting seat 410 , and the other end is passed through the through hole 423 .
[0037] Specifically, when the speaker 510 generates sound and vibration, the guide rod 440 can slide along the through hole 423. Because the through hole 423 is opened along the gravity direction, the relative movement of the speaker 500 and the mounting base 100 can be restricted, ensuring that the two can only move relative to each other in the gravity direction, and not in the horizontal direction. In this way, the shock absorption effect of the shock absorber 400 can be improved, and the sound played by the speaker 500 can be further prevented from being distorted.
[0038] In a specific embodiment, the shock absorber 400 further includes a buffer sleeve 450. The buffer sleeve 450 is installed at the through hole 423, and one end of the buffer sleeve 450 away from the first connecting seat 410 protrudes from the through hole 423, and the guide rod 440 is passed through the buffer sleeve 450, and the guide rod 440 includes a head 441 disposed away from the first connecting seat 410, and the outer contour of the head 441 is larger than the inner contour of the buffer sleeve 450.
[0039] Specifically, since the outer contour of the head 441 is larger than the inner contour of the buffer sleeve 450, the head 441 cannot pass through the buffer sleeve 450. Therefore, the implementation of this embodiment can establish a constraint between the guide rod 440 and the second connecting seat 420 to prevent the guide rod 440 from being separated from the second connecting seat 420. Since the end of the buffer sleeve 450 away from the first connecting seat 410 protrudes through the hole 423, and since the outer contour of the head 441 is larger than the inner contour of the buffer sleeve 450, when the spring 430 recovers its deformation from the compressed state, the head 441 of the guide rod 440 can collide with the position of the protruding through hole 423 of the buffer sleeve 450, thereby achieving a buffering effect and avoiding the generation of noise.
[0040] In a specific embodiment, both ends of the top and bottom of the buffer sleeve 450 protrude from the through hole 423 , and convex edges 451 extending radially along the through hole 423 are provided at the positions protruding from the through hole 423 .
[0041] Specifically, the convex edges 451 on the top and bottom sides can respectively abut against the two sides of the hole wall of the through hole 423, so that even without using adhesive, the buffer sleeve 450 can be firmly installed in the through hole 423, which is not only convenient to assemble but also very stable and reliable.
[0042] In a specific embodiment, a washer 460 is sandwiched between the buffer sleeve 450 and the head 441. The washer 460 is sleeved on the guide rod 440. The outer contour of the washer 460 is larger than the contour of the head 441. The outer contour of the flange 451 is matched with the outer contour of the washer 460. Compared with the embodiment in which the head 441 is directly connected to the buffer sleeve 450, the contact area between the washer 460 and the buffer sleeve 450 is larger in this embodiment, so the buffer sleeve 450 can be better utilized to unload force.
[0043] In one embodiment, a plurality of shock absorbers 400 are provided, so that the shock absorbing effect can be improved to further avoid distortion of the sound played by the speaker 500, and further avoid noise and hum, and the user experience is excellent.
[0044] In a specific embodiment, four shock absorbers 400 are provided, and the four shock absorbers 400 are respectively connected to each corner of the sound box 500, so that the shock absorption effect is better.
[0045] In one embodiment, the total weight of the mounting base 100 and all components mounted on the mounting base 100 is ≥ 4000 g.
[0046] Specifically, the sum of the weights of the mounting base 100 and the components mounted on the mounting base 100 is designed to be relatively heavy, which can effectively reduce the impact of the speaker 510 in the speaker box 500 on the mounting base 100 and the components mounted on the mounting base 100 when the speaker 510 in the speaker box 500 makes a sound, thereby avoiding distortion of the sound played by the speaker box 500 and avoiding noise and humming.
[0047] In a specific embodiment, the total weight of the mounting base 100 and all components mounted on the mounting base 100 is ≤7000 g.
[0048] Specifically, if the total weight of the mounting base 100 and all the components mounted on the mounting base 100 is too large, it will be inconvenient to transport the integrated record player 1000. Therefore, in this embodiment, the total weight of the mounting base 100 and all the components mounted on the mounting base 100 is limited to a range of ≥4000g and ≤7000g.
[0049] In order to make the sum of the weight of the mounting base 100 and the components on the mounting base 100 ≥4000g and ≤7000g, the mounting base 100 can be made of a material with a larger weight per unit volume, such as a density board, or a counterweight can be installed on the mounting base 100.
[0050] In a specific embodiment, the cartridge 300 is electrically connected to the speaker 500 via a flexible wire to further avoid distortion of the sound played by the speaker 500 and further avoid noise and hum.
[0051] Specifically, holes for passing the soft wires are provided at the bottom of the mounting base 100 and the top of the sound box 500, so that the soft wires are not easily observed by the user, thereby improving the aesthetics of the integrated record player 1000.
[0052] The embodiment of the utility model shows an integrated record player 1000, which includes a mounting base 100, a cartridge 300, a turntable mechanism 200, a shock absorber 400 and a speaker 500. The cartridge 300 and the turntable mechanism 200 are both mounted on the mounting base 100. The turntable mechanism 200 is used to drive the record to rotate, the cartridge 300 is used to cooperate with the turntable mechanism to obtain audio information of the record, and the speaker 500 is electrically connected to the cartridge 300. Specifically, one end of the shock absorber 400 is connected to the mounting base 100, and the other end is connected to the speaker 500, so that the speaker 500 is layered and spaced at the bottom of the mounting base 100. In this way, the vibration generated by the speaker 510 in the speaker 500 when making a sound is not easily transmitted to the mounting base 100, thereby ensuring the stability of the turntable mechanism 200 and the cartridge 300 on the mounting base 100 when working, thereby avoiding the sound distortion played by the speaker 500, and avoiding the generation of noise and hum, and the user experience is excellent.
[0053] 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.
