Description

Technical Field

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

[0002] Currently, integrated turntables combine the speaker and record module into one unit, thus possessing advantages such as high integration, small footprint, and ease of use. Compared with traditional separate turntables, they are gradually becoming the mainstream product form.

[0003] However, the integration of the speaker enclosure and record module (including the matching turntable assembly and tonearm assembly) faces significant vibration interference problems. To solve this problem, existing technologies typically employ a solution of adding a support plate between the speaker enclosure and the record module, and using vibration damping components to elastically connect the support plate to the speaker enclosure. The damping effect of the vibration damping components reduces the transmission of speaker vibrations to the record module, thereby ensuring the stability of record playback.

[0004] Meanwhile, to facilitate user control of the record player's playback status (such as start / stop, speed adjustment, and volume control), the control module typically needs to be located in an easily accessible position. Based on the integrated turntable's structural layout, the support plate, serving as the mounting carrier for the record module and situated in the visible external area, naturally becomes the primary location for the control module. However, the control module requires electrical connection to the main control circuit board inside the speaker to transmit control signals, making wiring and securing difficult and hindering the simplification of wiring arrangements.

[0026] 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.

[0027] like Figure 1 and Figure 4As shown, this utility model embodiment provides a turntable 100, including: a speaker 110, a control module 120, and a support plate 130 connected to the speaker 110 via a vibration damping component 140. The support plate 130 is provided with a turntable assembly 150 and a tonearm assembly 160. The speaker 110 is provided with a circuit board 111 that is electrically connected to the turntable assembly 150 and the tonearm assembly 160 respectively, and a sound-generating module 112 connected to the circuit board 111. The circuit board 111 is connected to the back side of the speaker 110, the sound-generating module 112 is connected to the front side of the speaker 110, and the control module 120 is electrically connected to the circuit board 111 and is located on the left or right side of the speaker 110.

[0028] Specifically, by placing the circuit board 111 on the back of the speaker 110 and the sound-emitting module 112 on the front of the speaker 110, the internal layout of the speaker 110 becomes more regular, avoiding space waste and interference caused by cluttered component distribution. The control module 120 is located on the side of the speaker 110, which retains the user's easy-to-access operation convenience while being removed from the vibration-sensitive area of ​​the support plate 130, reducing the vibration problem caused to the support plate 130 when operating the control module 120. In addition, by moving the control module 120 to the left or right side of the speaker 110, and with the circuit board 111 located on the back of the speaker 110, both are on the fixed structure of the speaker 110, without needing to cross the elastically connected support plate 130 and speaker 110, greatly reducing the difficulty of wiring and fixing, significantly simplifying the connection wiring, and facilitating production assembly and later maintenance.

[0029] It should be noted that the vibration damping assembly 140, platter assembly 150, and tonearm assembly 160 all adopt commonly used structural forms to ensure the normal functioning of the turntable 100. Additionally, the control module 120 is located on the left or right side of the speaker 110, and is positioned close to the front of the speaker 110 for easy user operation.

[0030] like Figure 2 As shown, the speaker 110 includes a housing 113, a first partition 114 disposed inside the housing 113, and a second partition 115 abutting against the first partition 114, so that the housing 113 is divided into a control cavity 116 and two sound cavities 117 corresponding to the control cavity 116. The circuit board 111 is located inside the control cavity 116. Each sound cavity 117 is provided with a sound-emitting module 112, and the control module 120 corresponds to one of the sound cavities 117.

[0031] Specifically, the housing 113 is divided into a control cavity 116 and two sound cavities 117 by the cooperation of the first partition 114 and the second partition 115. The circuit board 111 is placed in the control cavity 116, and the sound-emitting modules 112 are placed in the independent sound cavities 117. This avoids the vibration and electromagnetic interference generated by the sound-emitting modules 112 during operation from directly affecting the circuit board 111, and also prevents the circuit signals of the circuit board 111 from interfering with the sound-emitting modules 112, thus improving the stability of the operation of each component. In addition, the control module 120 corresponds to one of the sound cavities 117, which allows the control module 120 to be close to the front of the speaker 110, making it convenient for the user to operate the control module 120. Moreover, the connecting wire between the circuit board 111 and the control module 120 can be routed in the same strand as the connecting wire of the sound-emitting module 112, and can be separated from the control module 120 at the end, which also helps to simplify the wiring.

[0032] like Figure 3 As shown, the control module 120 includes a fixed panel 122, a PCB board 124 electrically connected to the circuit board 111, and a control knob 126 connected to the PCB board 124. The control knob 126 is connected to the fixed panel 122, and the fixed panel 122 is fixedly connected to the housing 113.

[0033] Specifically, PCB board 124 is electrically connected to circuit board 111, undertaking the function of transmitting control signals; control knob 126 is connected to PCB board 124, serving as a component directly operated by the user, used to realize functions such as start / stop, speed adjustment, and volume control; control knob 126 is also connected to fixed panel 122, which is used to fix the overall control module 120. In addition, through the fixed connection between fixed panel 122 and speaker housing 113, the control module 120 is firmly installed on speaker 110, avoiding loosening or displacement of control module 120 due to vibration or operation during use, enhancing the structural stability of control module 120 and extending its service life.

[0034] Please continue to refer to this. Figure 3 The PCB board 124 is also connected to an indicator light post 128, the end of which protrudes from the fixed panel 122.

[0035] Specifically, the indicator light column 128 serves as a signal indicator component. It is connected to the PCB board 124 to receive signals transmitted from the PCB board 124, and its exposed end on the fixed panel 122 allows the user to easily observe the status of the indicator light column 128. This allows the user to easily determine the operating status of the turntable 100 based on the status of the indicator light column 128, thus improving the user experience.

[0036] like Figure 3 and Figure 4As shown, the housing 113 is provided with a through hole 1132 and a recessed groove 1134 located outside the through hole 1132. The fixed panel 122 is inserted into the recessed groove 1134 and connected to the housing 113 by fasteners 129 (screws or bolts). The PCB board 124 extends into the speaker 110 through the through hole 1132.

[0037] Specifically, the PCB board 124 extends into the speaker enclosure 110 through the through-hole 1132, facilitating electrical connection between the PCB board 124 and the circuit board 111. The fixing panel 122 is inserted into the recessed groove 1134, allowing the outer surface of the fixing panel 122 to be basically flush with the surface of the speaker enclosure 110 housing 113 or to form a regular stepped transition. This avoids the cluttered appearance caused by the control module 120 protruding from the surface of the housing 113, improving the overall neatness and aesthetics of the turntable. In addition, the recessed groove 1134 provides a precise installation positioning reference for the fixing panel 122, allowing the fixing panel 122 to be quickly inserted into place and reducing assembly errors. At the same time, combined with the fixing effect of the fastener 129, a double fixation is achieved between the control module 120 and the housing 113.

[0038] like Figure 2 As shown, each sound cavity 117 is also provided with a sound guide tube 118, and one of the sound guide tubes 118 is connected to the left side of the speaker 110, and the other sound guide tube 118 is connected to the right side of the speaker 110.

[0039] Specifically, after the sound-generating module 112 emits sound within the sound cavity 117, the sound can be directionally transmitted to the outside of the speaker 110 via the sound guide tube 118. The sound guide tube 118 can regulate the direction and phase of sound propagation, avoiding problems such as muddiness and distortion caused by disordered sound reflection within the sound cavity 117. Furthermore, the presence of sound guide tubes 118 on both the left and right sides optimizes the stereo effect, enhancing the user's auditory experience. Additionally, when the sound-generating module 112 is operating, the air pressure within the sound cavity 117 changes with sound wave vibration. The sound guide tube 118 connects the sound cavity 117 to the outside, achieving a balance of air pressure inside and outside the sound cavity 117. This prevents the sound-generating module 112 from vibrating due to pressure imbalance, ensuring stable operation and further improving the stability and consistency of sound quality.

[0040] like Figure 5 As shown, the sound guide tube 118 includes a first expansion section 1182, a contraction section 1184, and a second expansion section 1186 connected in sequence, wherein the first expansion section 1182 or the second expansion section 1186 is fixedly connected to the housing 113.

[0041] Specifically, the "expansion section" refers to the part of the sound tube 118 where the diameter gradually increases, and the "contraction section" refers to the part of the tube where the diameter gradually decreases. The above structure can utilize the Venturi principle to increase the speed of sound waves as they pass through the sound tube 118, resulting in a wider sound coverage and better auditory effects.

[0042] like Figure 5 As shown, the sound guide tube 118 includes a first half and a second half, which are bonded together or snapped together.

[0043] Specifically, the sound guide tube 118 adopts a split structure design, which makes it easier to connect the sound guide tube 118 to the housing 113 and avoids the large diameter of the two ends affecting the connection between the sound guide tube 118 and the housing 113. In practical applications, the first half can be inserted into the housing 113 and fixed to the housing 113, and then the second half can be connected to the first half.

[0044] Please continue to refer to this. Figure 5 The first half is provided with a first pair of interfaces, and the second half is provided with a second pair of interfaces. The first pair of interfaces can be connected to the second pair of interfaces, and the connection between the first pair of interfaces and the second pair of interfaces forms a contraction section 1184.

[0045] Specifically, the matching design of the first and second pairs of interfaces provides a clear positioning benchmark for the docking of the first and second halves, ensuring no misalignment occurs during docking and improving docking accuracy. Simultaneously, the mating of the first and second pairs of interfaces enhances the connection strength between the first and second halves, preventing loosening after assembly and further ensuring the structural stability of the sound guide tube 118. It should also be noted that the inner ring of the first pair of interfaces can have a groove, and the outer ring of the second pair of interfaces can also have a corresponding cut. This allows for adhesive or snap-fit ​​connection of the first and second halves, making the inner and outer sides of the connection smoother, avoiding protruding edges, ensuring overall consistency, and preventing interference with sound waves when the sound guide tube 118 conducts sound waves.

[0046] like Figure 6 As shown, the turntable 100 also includes a cover, which is fastened to the support plate 130 or rotatably connected to the speaker 110. The cover is used to cover the turntable assembly 150 and tonearm assembly 160 on the support plate 130.

[0047] Specifically, the cover can effectively prevent dust, debris and other objects from falling into the turntable assembly 150 and tonearm assembly 160, avoiding impurities from affecting the rotational accuracy and working stability of the components; at the same time, when the record player is not in use or is moved, the cover can prevent the core components from being subjected to physical damage such as collisions and scratches, which is beneficial to protecting the record player 100.

[0048] 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.
