Description

Technical Field

[0001] This utility model relates to the field of record player technology, and in particular to a record player. Background Technology

[0002] A record player, also known as a phonograph, is a device that plays back the sound stored on a vinyl record. The surface of a record has spiral-shaped grooves that acoustically store sound on their walls, creating an uneven surface. The audio signal from the record is generated by the vibration of the stylus on the cartridge as it moves across the grooves, which is then amplified into an audio signal.

[0003] When playing records, record players need to maintain stable operating conditions. However, in record players with built-in speakers, the speakers vibrate when they are playing sound because they are fixed inside the cabinet. This vibration causes the record and cartridge to vibrate as well. These vibrations interfere with the audio signal that the cartridge reads from the record, resulting in sound distortion, noise, and ringing. This seriously affects the sound quality of the record player and greatly reduces the user experience.

[0004] To reduce the impact of vibration on sound quality, some existing record players have added vibration damping devices to improve playback sound quality. However, after adding vibration damping devices, the support plate for mounting the tonearm needs to be supported at a higher height, and the vibration damping devices are directly exposed to the outside, making the record player more bulky and not conducive to improving the overall compactness. Utility Model Content

[0005] The technical problem to be solved by this utility model embodiment is to provide a record player that can improve the overall compactness of the record player.

[0006] This utility model discloses a record player, comprising: a housing, a groove on the top of the housing, a vibration damping component on the bottom plate of the groove, a support panel inside the groove, the support panel being connected to the bottom plate via the vibration damping component, and a turntable assembly and a tonearm assembly being disposed on the support panel; and a speaker electrically connected to the tonearm assembly being disposed inside the housing, wherein there is a gap between the support panel and the inner wall of the housing.

[0007] Optionally, the record player further includes a cover rotatably connected to the housing, the cover covering the platter assembly and the tonearm assembly, and the cover engaging with the edge of the housing.

[0008] Optionally, a first bushing is provided on one side of the housing, and a second bushing is provided on one side of the cover. The first bushing and the second bushing are connected by a rotating shaft, wherein the rotating shaft is L-shaped, one end of the rotating shaft is rotatably connected to the first bushing, and the other end of the rotating shaft is fixedly connected to the second bushing.

[0009] Optionally, the record player further includes a control panel disposed within the housing, the control panel having a control knob, a gap between the control panel and the support panel, the plane of the control panel being flush with the plane of the support panel, and the top edge of the housing being flush with the top edge of the housing.

[0010] Optionally, positioning holes are provided at the four corners of the base plate, and part of the vibration damping component passes through the positioning holes. The vibration damping component is connected to the support panel by fasteners.

[0011] Optionally, the vibration damping assembly includes a first connecting seat, a pressure plate, an elastic element, and a second connecting seat. The first connecting seat is connected to the base plate via the pressure plate, and the second connecting seat is connected to the support panel via the fastener. The second connecting seat extends through the pressure plate into the first connecting seat. The elastic element is located between the first connecting seat and the second connecting seat to allow the first connecting seat and the second connecting seat to elastically abut against each other.

[0012] Optionally, the first connecting seat is provided with a limiting protrusion, and the second connecting seat is formed with a limiting groove corresponding to the limiting protrusion. One end of the elastic member is located in the limiting groove, and the other end of the elastic member is held at the limiting protrusion.

[0013] Optionally, the second connecting seat has a retaining part at one end extending into the first connecting seat, and a vibration damping sleeve is fitted on the retaining part so that the retaining part abuts against the pressure plate through the vibration damping sleeve.

[0014] Optionally, the holding part consists of a plurality of card platforms arranged in a ring array on the outer ring of the first connecting seat. The vibration damping sleeve includes a vibration damping body and a plurality of card slots disposed on the inner side of the vibration damping body. The card slots are arranged in a one-to-one correspondence with the card platforms. An elastic card protrusion is provided between adjacent card slots. The outer ring of the vibration damping body is provided with a plurality of elastic protrusions, and the elastic protrusions correspond one-to-one with the elastic card protrusions.

[0015] Optionally, the outer ring of the first connecting seat is provided with a flange, and the pressure plate connects the first connecting seat to the base plate through the flange. A sealing ring is provided on the side of the flange away from the pressure plate, and the sealing ring abuts against the flange and the base plate.

[0016] Compared with the prior art, the beneficial effects of the record player provided by this utility model embodiment are as follows: By connecting the support panel set in the groove to the base plate through the vibration damping component, when the speaker inside the housing vibrates, the vibration of the housing is transmitted to the base plate. Due to the damping effect of the vibration damping component, the vibration transmitted to the support panel can be ignored, thus preventing the turntable assembly and tonearm assembly set on the support panel from being affected by vibration and thus impacting sound quality. Furthermore, the gap between the support panel and the inner wall of the housing prevents vibration from being transmitted to the support panel due to direct contact between the housing and the support panel. Additionally, by setting a groove at the top of the housing, when the vibration damping component is set on the bottom plate of the groove, the vibration damping component is shielded by the housing and not directly exposed to the outside, which helps maintain the consistency of the record player's appearance. At the same time, setting the vibration damping component on the bottom plate of the groove helps reduce the height of the support panel, thus improving the overall compactness of the record player.

[0028] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0029] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model embodiment provides a record player 100, including: a housing 110, a groove 112 is provided on the top of the housing 110, a vibration damping component 120 is provided on the bottom plate 1122 of the groove 112, a support panel 130 is provided in the groove 112, the support panel 130 is connected to the bottom plate 1122 through the vibration damping component 120, and a turntable assembly 140 and a tonearm assembly 150 are provided on the support panel 130. A speaker electrically connected to the tonearm assembly 150 is provided in the housing 110, wherein there is a gap between the support panel 130 and the inner wall of the housing 110.

[0030] Specifically, by connecting the support panel 130, which is located within the groove 112, to the base plate 1122 via the vibration damping component 120, when the speaker inside the housing 110 vibrates, the vibration transmitted to the base plate 1122 is attenuated by the vibration damping component 120, making the vibration transmitted to the support panel 130 negligible. This prevents the turntable assembly 140 and tonearm assembly 150 mounted on the support panel 130 from vibrating and affecting the sound quality. Furthermore, the gap between the support panel 130 and the inner wall of the housing 110 prevents direct contact between the housing 110 and the support panel 130 from transmitting vibration to the support panel 130. Additionally, by providing the groove 112 at the top of the housing 110 and mounting the vibration damping component 120 on the base plate 1122 of the groove 112, the vibration damping component 120 is shielded by the housing 110 and not directly exposed, thus maintaining the uniformity of the record player 100's appearance. Meanwhile, the shock-absorbing components are set on the bottom plate 1122 of the groove 112, which helps to reduce the height of the support panel 130 and improve the overall compactness of the record player 100.

[0031] like Figure 1 As shown, the record player 100 also includes a cover 160, which is rotatably connected to the housing 110. The cover 160 is used to cover the turntable assembly 140 and the tonearm assembly 150, and the cover 160 is aligned with the edge of the housing 110.

[0032] Specifically, the edge of the cover 160 is flush with the edge of the housing 110 to facilitate a tight seal and prevent dust from falling onto the tonearm assembly 150 and the platter assembly 140. When changing a record, simply open the cover 160; after changing, fasten the cover 160 back onto the housing 110. Understandably, the cover 160 can be made of a transparent material to allow for easy observation of the record player 100's operating status, enhancing the user experience. Simultaneously, during use, the cover 160 does not directly contact the support panel 130, preventing vibrations from the housing 110 from being transmitted to the support panel 130 via the cover 160, thus improving stability. Furthermore, a protective pad 166, made of silicone, is provided along the edge of the cover 160 to prevent direct collision between the cover 160 and the housing 110, protecting both.

[0033] like Figure 4 and Figure 5 As shown, a first bushing 114 is provided on one side of the housing 110, and a second bushing 162 is provided on one side of the cover 160. The first bushing 114 and the second bushing 162 are connected by a rotating shaft 164. The rotating shaft 164 is L-shaped, with one end of the rotating shaft 164 rotatably connected to the first bushing 114 and the other end of the rotating shaft 164 fixedly connected to the second bushing 162.

[0034] Specifically, a first bushing 114 is provided on one side of the housing 110, and a second bushing 162 is provided on one side of the cover 160, facilitating the connection of the first bushing 114 and the second bushing 162 via a rotating shaft 164. In this embodiment, by setting the rotating shaft 164 to an L-shape, only one end of the rotating shaft 164 needs to be rotatably connected to the first bushing 114, and the other end of the rotating shaft 164 needs to be fixedly connected to the second bushing 162, thus achieving a rotatable connection between the housing 110 and the cover 160. In addition, a limiting groove 1242 is provided on the first bushing 114, and a corresponding stop block is provided on the rotating shaft 164, enabling the cover 160 to open relative to the housing 110 at a preset angle, facilitating the limitation of the opening angle of the cover 160 and preventing accidental bumps caused by an excessively large opening angle.

[0035] like Figure 3 As shown, the record player 100 also includes a control panel 170 disposed inside the housing 110. The control panel 170 is provided with a control knob 172. There is a gap between the control panel 170 and the support panel 130. The plane of the control panel 170 is flush with the plane of the support panel 130 and is flush with the top edge of the housing 110.

[0036] Specifically, the control panel 170 located within the housing 110 allows for convenient operation of the control knobs 172, such as controlling the playback or stop of the record player 100, or controlling the volume of the record player 100. Multiple control knobs 172 can be provided to facilitate operation of different functions. Because there is a gap between the control panel 170 and the support panel 130, operating the control knobs 172 will not affect the support panel 130 or the playback effect, thus ensuring stability during use. Furthermore, the plane of the control panel 170 is flush with the plane of the support panel 130 and with the top edge of the housing 110, resulting in a smoother and more consistent top surface of the record player 100, improving both the user experience and aesthetics.

[0037] like Figure 3 and Figure 3 As shown, positioning holes are provided at the four corners of the base plate 1122, and part of the vibration damping component 120 passes through the positioning holes. The vibration damping component 120 is connected to the support panel 130 by fasteners 132.

[0038] Specifically, by providing positioning holes at the four corners of the base plate 1122, the vibration damping component 120 is positioned within these holes, facilitating stable support of the support panel 130. Simultaneously, the vibration damping component 120 is connected to the support panel 130 via fasteners 132, ensuring reliable connection and preventing loosening. Bolts can be used to achieve this connection.

[0039] like Figure 6 , Figure 7 and Figure 8 As shown, the vibration damping assembly 120 includes a first connecting seat 121, a pressure plate 122, an elastic element 123, and a second connecting seat 124. The first connecting seat 121 is connected to the base plate 1122 via the pressure plate 122. The second connecting seat 124 is connected to the support panel 130 via a fastener 132. The second connecting seat 124 extends through the pressure plate 122 into the first connecting seat 121. The elastic element 123 is located between the first connecting seat 121 and the second connecting seat 124 so that the first connecting seat 121 and the second connecting seat 124 elastically abut against each other.

[0040] Specifically, the vibration damping module is connected to the base plate 1122 via a pressure plate 122. When connected to the base plate 1122, the first connecting seat 121 is confined between the pressure plate 122 and the base plate 1122 to limit the position of the first connecting seat 121. The pressure plate 122 and the base plate 1122 can be fastened together with screws to ensure stable positioning of the first connecting seat 121. Furthermore, the first connecting seat 121 and the second connecting seat 124 elastically abut against each other, and the second connecting seat 124 is connected to the support panel 130. When the speaker is emitting sound, the vibration transmitted from the housing 110 is first transmitted to the first connecting seat 121, and then to the elastic member 123. After reaching the elastic member 123, the vibration transmitted to the second connecting seat 124 is negligible due to the damping effect of the elastic member 123 itself, and will not affect the support panel 130, thereby reducing the impact of vibration on the tonearm assembly 150 and the turntable assembly 140.

[0041] like Figure 7 As shown, a limiting protrusion 1212 is provided in the first connecting seat 121, and a limiting groove 1242 corresponding to the limiting protrusion 1212 is formed in the second connecting seat 124. One end of the elastic member 123 is located in the limiting groove 1242, and the other end of the elastic member 123 is held at the limiting protrusion 1212.

[0042] Specifically, with the combined action of the limiting protrusion 1212 and the limiting groove 1242, both ends of the elastic element 123 can be limited to prevent displacement during the deformation of the elastic element 123 under force, thus ensuring stability during use. The elastic element 123 can be a compression spring or a compression spring with damping characteristics.

[0043] like Figure 8 As shown, the second connecting seat 124 has a retaining part 1244 at one end that extends into the first connecting seat 121. A damping sleeve 125 is fitted on the retaining part 1244 so that the retaining part 1244 abuts against the pressure plate 122 through the damping sleeve 125.

[0044] Specifically, by providing a damping sleeve 125 on the holding part 1244, when the holding part 1244 is held against the pressure plate 122 by the elastic force of the elastic member 123, rigid resistance between the two is avoided. When transmitting vibration, the damping sleeve 125 can absorb vibration, further reducing the transmission of longitudinal vibration.

[0045] Optionally, the holding part 1244 consists of a plurality of card platforms arranged in a ring array on the outer ring of the first connecting seat 121. The vibration damping sleeve 125 includes a vibration damping body 1252 and a plurality of card slots 1254 disposed on the inner side of the vibration damping body 1252. The card slots 1254 are arranged in a one-to-one correspondence with the card platforms. An elastic protrusion 1256 is provided between adjacent card slots 1254. A plurality of elastic protrusions 1258 are provided on the outer ring of the vibration damping body 1252, and the elastic protrusions 1258 correspond one-to-one with the elastic protrusions 1256.

[0046] Specifically, by configuring the retaining part 1244 as a plurality of retaining platforms arranged in a ring array around the outer ring of the first connecting seat 121, the retaining platforms can cooperate with the retaining groove 1254 on the inner side of the vibration damping body 1252 to achieve the connection and alignment of the retaining part 1244 and the vibration damping sleeve 125. When the elastic protrusion 1258 cooperates with the first connecting seat 121 to reduce lateral vibration, since the elastic protrusion 1258 corresponds to the elastic retaining protrusion 1256, a larger buffer and vibration damping area can be provided at the location of the elastic protrusion 1258 to achieve a better vibration damping effect. In addition, the thickness of the vibration damping body 1252 itself is sandwiched between the pressure plate 122 and the retaining platforms to better reduce longitudinal vibration.

[0047] like Figure 7 and Figure 8 As shown, the outer ring of the first connecting seat 121 is provided with a flange 1214. The pressure plate 122 connects the first connecting seat 121 to the base plate 1122 through the flange 1214. A sealing ring 126 is provided on the side of the flange 1214 away from the pressure plate 122. The sealing ring 126 abuts between the flange 1214 and the base plate 1122.

[0048] Specifically, by providing a sealing ring 126 on the side of the flange 1214 away from the pressure plate 122, when the first connecting seat 121 is engaged with the positioning hole, the sealing ring 126 abuts between the first connecting seat 121 and the base plate 1122. In this way, it can not only play a sealing role to prevent dust and other foreign objects from entering the housing 110 from the positioning hole, but also play a vibration absorption role to reduce the transmission of vibration.

[0049] It should be understood that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Those skilled in the art can modify the technical solutions described in the above embodiments, or make equivalent substitutions for some of the technical features; and all such modifications and substitutions should fall within the protection scope of the appended claims of this utility model.
