[0024] 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.

[0025] like Figures 1 to 3As shown, this utility model embodiment provides a record player 100, including: a housing 110, and a first partition 112 and a second partition 114 arranged in a T-shape inside the housing 110. A top plate 117 is provided on the first partition 112 and the second partition 114, so that a functional cavity 115 and two sound cavities 116 are formed inside the housing 110. A circuit board 120 is provided inside the functional cavity 115, and a sound-generating unit 130 is provided inside each sound cavity 116. A support plate 118 is provided on the top plate 117, and a tonearm assembly 140 and a turntable assembly 150 are provided on the support plate 118. The support plate 118 is connected to the top plate 117 through multiple vibration damping components 160, some of which correspond to the functional cavity 115 and some of which correspond to the sound cavities 116.

[0026] Specifically, by using a first partition 112 and a second partition 114 arranged in a T-shape within the housing 110, the space within the housing 110 is divided into a functional cavity 115 and two acoustic cavities 116, wherein the two acoustic cavities 116 can be set to the same size. Furthermore, by providing a top plate 117 on the first partition 112 and the second partition 114, the top plate 117 is stably supported. This allows the support plate 118 on the top plate 117, and the corresponding tonearm assembly 140 and turntable assembly 150 mounted on the support plate 118, to be stably supported, ensuring reliability during use. To prevent the vibration of the sound-generating unit 130 within the acoustic cavity 116 from affecting the tonearm assembly 140 and turntable assembly 150, the support plate 118 is connected to the top plate 117 via multiple vibration damping components 160 to reduce the transmission of vibration to the support plate 118. It should be noted that the structural form of the vibration damping component 160 is not limited in this application embodiment, as long as it can weaken the transmission of vibration. In addition, in order to ensure the stable support of the vibration damping component 160 to the support plate 118, four vibration damping components 160 can be set, two of which correspond to the functional cavity 115 and the other two correspond to the sound cavity 116 respectively, so as to reduce the impact on the sound generating unit 130 in the sound cavity 116.

[0027] The record player 100 provided in this application embodiment uses a first partition 112 and a second partition 114 arranged in a T-shape within the housing 110, and a top plate 117 disposed on the first partition 112 and the second partition 114, to form a functional cavity 115 and two sound cavities 116 within the housing 110. This allows a circuit board 120 to be disposed within the functional cavity 115, and a sound-generating unit 130 to be disposed within each sound cavity 116. This arrangement of the sound-generating unit 130 within the sound cavity 116 avoids placing other components such as the circuit board 120 within the sound cavity 116, thereby reducing sound reflection and scattering, and thus minimizing the impact on the sound-generating unit 130. Furthermore, to further improve sound quality, a support plate 118 is connected to the top plate 117 via multiple vibration damping components 160 to reduce the impact of vibrations caused by the sound-generating unit 130 during sound generation on the support plate 118, ensuring the smooth operation of the corresponding tonearm assembly 140 and turntable assembly 150 disposed on the support plate 118. Meanwhile, some vibration damping components 160 correspond to the functional cavity 115, and some vibration damping components 160 correspond to the sound cavity 116, so as to minimize the impact of the vibration damping components 160 on the sound output of the sound-producing unit 130. By adopting the above configuration, the sound quality of the record player 100 can be improved.

[0028] like Figure 3 and Figure 4 As shown, the turntable assembly 150 includes a drive motor 152 mounted on a support plate 118 and a turntable 154 rotatably connected to the support plate 118. The drive motor 152 is connected to the turntable 154 in a transmission connection.

[0029] Specifically, the drive motor 152 provides the necessary power for the rotation of the turntable 154. The transmission connection between the drive motor 152 and the turntable 154 can take various forms. This embodiment provides a simple example: for instance, a synchronous pulley can be installed on the drive motor 152, and a synchronous belt can be installed on the synchronous pulley. The synchronous belt is connected to the inner disc of the turntable 154 to drive the rotation of the turntable 154. Alternatively, an elastic roller can be installed on the drive motor 152, and the elastic roller is directly connected to the inner disc of the turntable 154 to drive the rotation of the turntable 154. In this way, the record placed on the turntable 154 can rotate with the turntable 154, playing sound in cooperation with the tonearm assembly 140 and the sound-producing unit 130.

[0030] like Figure 2 , Figure 3 and Figure 4As shown, the drive motor 152 extends through the top plate 117 into the functional cavity 115, and the drive motor 152 is electrically connected to the circuit board 120 through the first wire; the turntable 154 includes a shaft 1542 and a disk body 1544 connected to each other, a limiting plate 1122 is provided on the first partition plate 112, a limiting groove 1122a is provided on the limiting plate 1122, a bushing 1172 is provided on the support plate 118 and sleeved on the outer ring of the shaft 1542, a ball 1174 is provided in the bushing 1172, and the ball 1174 abuts against the limiting groove 1122a and one end of the shaft 1542.

[0031] Specifically, the drive motor 152 extends through the top plate 117 into the functional cavity 115, facilitating electrical connection to the circuit board 120 via the first wire. Additionally, the turntable 154 is connected to a shaft 1542 and a disc 1544. The shaft 1542 is rotatably connected to the support plate 118, while the disc 1544 carries the record. When the turntable 154 is rotatably connected to the support plate 118 via the shaft 1542, a bushing 1172 fitted around the outer ring of the shaft 1542 facilitates the limiting of the shaft 1542. Furthermore, a bearing can be installed between the shaft 1542 and the bushing 1172 to ensure quiet operation and smooth rotation. The bushing 1172 on the support plate 118 extends to the top plate 117 to cooperate with the limiting plate 1122. The ball bearing 1174 installed inside the bushing 1172 abuts against the limiting groove 1122a and one end of the shaft 1542, which can prevent the shaft 1542 from moving downward, thus ensuring the reliability of the height of the turntable 154 when it rotates. At the same time, the cooperation between the ball bearing 1174 and the shaft 1542 can prevent any impact on the rotation of the shaft 1542.

[0032] like Figure 4 As shown, the tonearm assembly 140 includes a connecting seat 142 connected to the support plate 118, and a tonearm 144 disposed on the connecting seat 142. A second wire connected to the circuit board 120 is led out from the connecting seat 142. A wire hole 1176 is provided at the position corresponding to the functional cavity 115 on the top plate 117 so that the second wire can pass through.

[0033] Specifically, the tonearm 144 on the connector 142 is used to cooperate with the record on the turntable 154 to read audio information, and is connected to the circuit board 120 through the second wire led out from the connector 142 to ensure the conversion of electrical signals and sound signals. In addition, by providing a wire hole 1176 at the position corresponding to the functional cavity 115 on the top plate 117, the routing of the second wire is facilitated and the difficulty of wiring connection is reduced.

[0034] like Figure 2As shown, the sound-generating unit 130 includes a tweeter 132 and a woofer 134 connected to each other. The tweeter 132 and the woofer 134 are respectively disposed on one side wall of the housing 110. A through hole 1124 is provided on the first partition plate 112 so that the sound-generating unit 130 is connected to the circuit board 120 through a third wire passing through the through hole 1124.

[0035] Specifically, by configuring the sound-generating unit 130 as a connected tweeter 132 and woofer 134, the sound range can be widened, sound distortion can be avoided, and the required sound quality and bass effect can be guaranteed. When connecting the sound-generating unit 130 to the circuit board 120, in order to reduce the difficulty of wiring, a through hole 1124 can be provided on the first partition 112 so that the third wire can pass through the through hole 1124 to connect the sound-generating unit 130 and the circuit board 120.

[0036] like Figure 2 As shown, a sound guide tube 170 is also provided inside the sound cavity 116. The sound guide tube 170 is connected to the other side wall of the housing 110, and the side wall of the housing 110 where the sound guide tube 170 is located is adjacent to the side wall of the housing 110 where the sound generating unit 130 is located.

[0037] Specifically, by placing the side wall of the housing 110 containing the sound guide tube 170 adjacent to the side wall of the housing 110 containing the sound-generating unit 130, sound waves can be transmitted from both the front and left / right sides of the record player, thus enhancing the stereo effect. Furthermore, when the sound-generating unit 130 vibrates, the diaphragms of the tweeter 132 and woofer 134 are exposed to produce sound. The sound waves generated by the vibration are amplified within the sound cavity 116, enhancing the bass. Subsequently, the sound guide tube 170 radiates the sound waves to the outside of the housing 110, where they are superimposed with the synchronous frequency sound waves emitted by the sound-generating unit 130, resulting in lower frequency and deeper bass. Simultaneously, the connection between the sound guide tube 170 and the outside of the housing 110 prevents the sound from becoming muffled, thus improving the sound quality of the record player 100. Understandably, to prevent external dust or insects from entering the housing 110, a mesh cover can be installed at the outlet section of the sound guide tube 170 for protection.

[0038] In an optional embodiment of this application, the diameter of the openings at both ends of the sound guide tube 170 is larger than the diameter of the middle tube.

[0039] By using the above method, the Venturi effect can be utilized to enhance the sound field of the generator unit and improve the sound quality when the record player plays sound.

[0040] like Figure 5As shown, the sound guide tube 170 includes a first connecting section 172 and a second connecting section 174. A first buckle 1722 is provided on the first connecting section 172, and a second buckle 1742 is provided on the second connecting section 174. The first connecting section 172 can dock with the second connecting section 174, and the first buckle 1722 can engage with the second buckle 1742. The sound guide tube 170 is connected to the housing 110 through the first connecting section 172.

[0041] Specifically, by setting the sound guide tube 170 as a detachable first connecting section 172 and second connecting section 174, it is convenient to connect the second connecting section 174 to the first connecting section 172 to form a complete sound guide tube 170 after the first connecting section 172 is connected to the housing 110, which helps to reduce assembly difficulty and improve assembly efficiency.

[0042] like Figure 4 As shown, the outer side of the side wall of the housing 110 where the sound-emitting unit 130 is located is detachably connected to a decorative panel 180.

[0043] Specifically, the trim panel 180 can protect the sound unit 130, prevent the diaphragms of the tweeter 132 and woofer 134 from being affected by external factors, and improve the overall consistency of the record player 100.

[0044] like Figure 1 As shown, a control panel 190 is also fixedly connected to the top plate 117. The control panel 190 is equipped with a control knob 192, and there is a gap between the control panel 190 and the support plate 118.

[0045] Specifically, by providing a gap between the control panel 190 and the support plate 118, it is possible to prevent the operation of the control knob 192 from affecting the support plate 118, thereby affecting the smooth operation of the turntable assembly 150 and the tonearm assembly 140, which helps to ensure stability during use.

[0046] 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.
