Description

Technical Field

[0001] The utility model relates to the technical field of record players, in particular to a black vinyl record device. Background Art

[0002] A vinyl record device, also known as a phonograph, is a sound playback device that stores sound in the concave and convex textures carved on the surface of the record using acoustic methods. When you need to play music, place the record on the turntable of the vinyl record device, and the turntable drives the record to rotate under the stylus. The audio information collected by the stylus is amplified by the circuit and output to a device with a speaker to play the music.

[0003] Some vinyl record devices on the market include a box, a tonearm assembly is installed on the top of the box, and a speaker electrically connected to the tonearm assembly is installed inside the box. When the speaker in the speaker produces sound, it will vibrate, which in turn causes the cartridge of the tonearm assembly and the record installed on the vinyl record device to vibrate. Because the audio signal of the vinyl record device itself relies on the stylus on the cartridge to vibrate after scratching the concave and convex texture on the record, and then amplified into an audio signal, the vibration generated when the speaker produces sound may cause the audio signal to be abnormal, which in turn causes the sound played by the speaker to be distorted, and generates noise and hum, affecting the sound quality of the sound played by the vinyl record device.

DETAILED DESCRIPTION

[0025] 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.

[0026] In order to solve the problem that the speakers in the speakers of some vinyl record devices on the market will vibrate when sounding, which in turn causes the cartridge and the record installed on the vinyl record device to vibrate, resulting in abnormal audio signals, and then causes the sound played by the speaker to be distorted, and generates noise and hum, affecting the sound quality of the sound played by the vinyl record device, the embodiments of the present application provide the following technical solutions to overcome the above problems.

[0027] like Figure 1 , Figure 2 and Figure 3 As shown, an embodiment of the utility model provides a vinyl record device 100, comprising: a box body 110, and a speaker arranged in the box body 110, a mounting seat 120 is arranged on the box body 110, and a turntable mechanism 130 and a tonearm assembly 140 are arranged on the mounting seat 120, a shock absorbing module 150 is arranged on the mounting seat 120, and a mounting hole 112 corresponding to the shock absorbing module 150 is arranged on the box body 110, so that the shock absorbing module 150 is clamped in the mounting hole 112.

[0028] Specifically, the turntable mechanism 130 provided on the mounting seat 120 is used to place the record, so as to cooperate with the tonearm assembly 140 to read the information stored on the record. The tonearm assembly 140 is electrically connected to the speaker through a circuit board, so that the read information is transmitted through the sound of the speaker. When the speaker makes a sound, vibration is generated, wherein a part of the vibration is transmitted along the work surface on which it is placed, and another part of the vibration is transmitted to the mounting seat 120. By providing a shock absorbing module 150 on the mounting seat 120, when the vibration is transmitted to the mounting seat 120, the shock absorbing effect of the shock absorbing module 150 is effectively reduced, thereby effectively reducing the influence of the sound of the speaker on the mounting seat 120. In addition, by providing the mounting hole 112 corresponding to the shock absorbing module 150 on the box 110, when the mounting seat 120 cooperates with the box 110, it only needs to be clamped in the mounting hole 112 by the shock absorbing module 150, which can avoid direct contact between the mounting seat 120 and the box 110, thereby ensuring the stability of the turntable mechanism 130 and the tonearm assembly 140 provided on the mounting seat 120 during operation. Among them, the mounting seat 120 provided on the box 110 can be understood as being provided at the left side, right side, top side, bottom side or inside of the box as required. In the preferred embodiment of the present application, the mounting seat 120 is provided on the upper surface of the box 110. Of course, the mounting seat 120 can also be provided in an embedded form as required, as long as a stable connection with the box 110 can be ensured.

[0029] The vinyl record device 100 provided in the embodiment of the present application is conducive to reducing the overall occupied space by building the speaker into the box 110. At the same time, the turntable mechanism 130 and the tonearm assembly 140 are connected to the box 110 through the mounting seat 120, which can make the whole more compact. When in use, the speaker makes sound and generates vibration. Since the mounting seat 120 is connected to the box 110 through the shock-absorbing module 150, after the vibration generated by the speaker is transmitted to the box 110, it needs to be reduced by the shock-absorbing module 150 in the process of being transmitted to the mounting seat 120. In addition, by clamping the shock-absorbing module 150 in the mounting hole 112, it is equivalent to placing the mounting seat 120 on the box 110, and there is a certain gap between the two. Compared with a direct integrated connection, it can also better assist in reducing the transmission of vibration. The above form can reduce the vibration transmitted to the mounting seat 120 when the speaker in the speaker makes sound, thereby improving the sound quality during playback.

[0030] like Figure 2 and Figure 4 As shown, the shock absorbing module 150 includes a first connecting seat 152 connected to the mounting seat 120, and a second connecting seat 154 connected to the first connecting seat 152, wherein the first connecting seat 152 can move relative to the second connecting seat 154, and the first connecting seat 152 and the second connecting seat 154 are elastically supported by an elastic member 156.

[0031] Specifically, the shock absorbing module 150 is connected to the mounting seat 120 through the first connecting seat 152, and when the mounting seat 120 is matched with the box body 110, it is directly connected to the box body 110 through the second connecting seat 154. The second connecting seat 154 directly abuts against the box body 110, and the vibration transmitted from the box body 110 is first transmitted to the second connecting seat 154, and then transmitted to the elastic member 156. After being transmitted to the elastic member 156, the vibration finally transmitted to the first connecting seat 152 can be ignored due to the shock absorbing effect of the elastic member 156 itself, and will not affect the mounting seat 120.

[0032] like Figure 4 and Figure 5 As shown, the first connecting seat 152 includes a connecting portion 1522 and a clamping portion 1524 that are interconnected. The connecting portion 1522 is connected to the mounting seat 120 via a connecting member 160 . The clamping portion 1524 is located in the second connecting seat 154 and is clamped and limited with the second connecting seat 154 via the clamping portion 1524 .

[0033] Specifically, the connecting member 160 can be a bolt, and a fastening nut 162 is provided in the connecting portion 1522. When the connecting portion 1522 is connected to the mounting seat 120, the desired connection form can be achieved through the cooperation of the bolt and the fastening nut 162. In addition, the clamping portion 1524 can be provided in the form of a rib provided on the edge of the connecting portion 1522 to achieve the required position limiting cooperation. The clamping portion 1524 and the second connecting seat 154 are clamped and limited, so that the first connecting seat 152 can be prevented from being separated from the second connecting seat 154 under the action of the elastic member 156. At the same time, the elastic member 156 can support the force transmitted from the mounting seat 120 to achieve a balance between them, so as to ensure the stability of the connection.

[0034] like Figure 4 and Figure 5 As shown, the second connecting seat 154 includes a seat body 1542 and a cover plate 1544 connected to the seat body 1542. A accommodating space is formed in the seat body 1542, a limited position cavity is set in the connecting part 1522, the elastic member 156 is set in the accommodating space, and one end of the elastic member 156 is located in the limited position cavity.

[0035] Specifically, by configuring the second connection seat 154 as a split form of the seat body 1542 and the cover plate 1544, it is convenient to assemble and align with the first connection seat 152, and it is also convenient to configure the elastic member 156, which is conducive to reducing the difficulty of assembly. When in use, the elastic member 156 has a certain amount of activity space in the accommodating space. At the same time, the limiting cavity limits the elastic member 156 to prevent the elastic member 156 from being misaligned due to force, thereby ensuring stability during use.

[0036] like Figure 4As shown, a limiting protrusion 157 is disposed in the seat body 1542 , and the limiting protrusion 157 corresponds to the connecting portion 1522 to limit the other end of the elastic member 156 .

[0037] With the above-mentioned form, the two ends of the elastic member 156 can be limited by the cooperation of the limiting protrusion 157 and the limiting cavity, so as to prevent the elastic member 156 from being misaligned during the deformation under force, thereby ensuring stability during use. Among them, the elastic member 156 can be a compression spring with compression elasticity or damping characteristics.

[0038] like Figure 4 and Figure 5 As shown, the shock absorbing module 150 further includes a shock absorbing sleeve 158 , which is sleeved on the clamping portion 1524 , so that the clamping portion 1524 is abutted against the cover plate 1544 through the shock absorbing sleeve 158 .

[0039] Specifically, by sleeve-mounting the shock-absorbing sleeve 158 on the clamping portion 1524, when the clamping portion 1524 is subjected to the elastic force of the elastic member 156 and abuts against the cover plate 1544, the rigid abutment between the two is avoided. When the clamping portion 1524 abuts against the cover plate 1544 through the shock-absorbing sleeve 158, the shock-absorbing sleeve 158 can play a role in absorbing vibration when transmitting vibration, thereby further reducing the transmission of vibration.

[0040] like Figure 5 As shown, in an optional embodiment of the present application, the clamping portion 1524 is an annular rib arranged on the outer ring of the connecting portion, the shock-absorbing sleeve 158 includes a shock-absorbing body 1582, and a plurality of elastic protrusions 1584 arranged on the outer ring of the shock-absorbing body 1582, and the shock-absorbing sleeve 158 is sleeved on the annular rib through the shock-absorbing body 1582.

[0041] Specifically, the annular rib can cooperate with the cover plate 1544 to achieve stable cooperation between the first connecting seat 152 and the second connecting seat 154, and can also make the shock absorbing body 1582 stably sleeved on the annular rib to prevent the shock absorbing body 1582 from loosening. Among them, the cross section of the shock absorbing body 1582 is U-shaped. When cooperating with the annular rib, the elastic member of the shock absorbing body 1582 can be sleeved on the annular rib. In addition, through the multiple elastic protrusions 1584 arranged on the outer ring of the shock absorbing body 1582, the elastic protrusions 1584 can cooperate with the inner wall of the seat body 1542 to reduce lateral vibration, and the thickness of the shock absorbing body 1582 itself is clamped between the cover plate 1544 and the annular rib to better reduce longitudinal vibration.

[0042] like Figure 6As shown, in another optional embodiment of the present application, the clamping portion 1524 is a plurality of clamping platforms arranged in a circular array on the outer circle of the connecting portion, the shock absorbing sleeve 158 includes a shock absorbing body 1582, and a plurality of clamping grooves 1586 arranged on the inner side of the shock absorbing body 1582, the clamping grooves 1586 are arranged in a one-to-one correspondence with the clamping platforms, and elastic clamping protrusions 1588 are arranged between adjacent clamping grooves 1586, and a plurality of elastic protrusions 1584 are arranged on the outer circle of the shock absorbing body 1582, and the elastic protrusions 1584 correspond to the elastic clamping protrusions 1588.

[0043] Specifically, by setting the clamping part 1524 in the form of a plurality of clamping platforms arranged in an annular array on the outer ring of the connection part, the clamping platform can cooperate with the cover plate 1544, and at the same time, the clamping platform can cooperate with the clamping groove 1586 on the inner side of the shock absorbing body 1582 to achieve the connection and alignment between the clamping part 1524 and the shock absorbing sleeve 158. The cross section of the shock absorbing body 1582 can be set to an L-shape, which is convenient for the connection and cooperation between the shock absorbing sleeve 158 and the clamping platform. When the elastic protrusion 1584 cooperates with the seat 1542 to achieve the reduction of lateral vibration, since the elastic protrusion 1584 corresponds to the elastic clamping protrusion 1588, a larger buffer shock absorbing belt can be provided at the location of the elastic protrusion 1584 to better achieve the shock absorbing effect. In addition, the thickness of the shock absorbing body 1582 itself is clamped between the cover plate 1544 and the clamping platform to better reduce the longitudinal vibration.

[0044] like Figure 5 As shown, the outer ring of the seat body 1542 is provided with a flange 1546, the cover plate 1544 is connected to the seat body 1542 through the flange 1546, and a sealing ring 159 is provided on the side of the flange 1546 facing away from the cover plate 1544, and the sealing ring 159 is supported between the seat body 1542 and the box body 110.

[0045] Specifically, when the mounting seat 120 is placed on the box body 110, the shock absorbing module 150 corresponds to the mounting hole 112 on the box body 110, so that the shock absorbing module 150 is clamped in the mounting hole 112. At this time, the shock absorbing module 150 is clamped with the box body 110 through the flange 1546 of the outer ring of the seat body 1542. In addition, by providing a sealing ring 159 on the side of the flange 1546 away from the cover plate 1544, when the seat body 1542 is matched with the mounting hole 112, the sealing ring 159 is abutted between the seat body 1542 and the box body 110, so that it can not only play a sealing role to prevent foreign matter from entering the interior of the box body 110 from the mounting hole 112, but also play a shock absorbing role to reduce the transmission of vibration.

[0046] like Figure 5 As shown, a limit locking protrusion 1547 is also provided on the flange 1546 , and a slot hole 1548 corresponding to the limit locking protrusion 1547 is provided on the cover plate 1544 , so that the cover plate 1544 can be engaged with the limit locking protrusion 1547 through the slot hole 1548 .

[0047] By adopting the above-mentioned form, when the cover plate 1544 and the seat body 1542 are matched, the cover plate 1544 and the seat body 1542 can be assisted in positioning to ensure smooth connection through fasteners such as screws.

[0048] like Figure 3 As shown, the outer circle of the mounting hole 112 is provided with a groove 114 so that the flange 1546 is retained in the groove 114 , and the seat body 1542 passes through the mounting hole 112 and is placed in the box body 110 .

[0049] Specifically, by providing a groove 114 on the outer ring of the mounting hole 112, when the shock absorbing module 150 is matched with the mounting hole 112, the second connection seat 154 can be limited, thereby limiting the shock absorbing module 150 as a whole to ensure the stability of the connection. It can be understood that there are four shock absorbing modules 150, which are respectively located at the four corners of the box body 110, so as to provide stable support and maximize the reduction of vibration transmission, thereby improving the sound quality during playback.

[0050] 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.
