Abstract
Description
Technical Field
[0001] This utility model relates to the field of digital-to-analog conversion technology, and in particular to a 64-bit R2R audio digital-to-analog converter. Background Technology
[0002] The 64-bit R2R audio digital-to-analog converter is based on an R2R resistor network architecture. It achieves high-fidelity conversion of digital audio signals to analog signals through the collaborative work of a high-precision resistor array and a 64-bit digital signal processing unit. Its core advantage lies in its ultra-high 64-bit resolution, which accurately captures subtle dynamics and low-frequency details in audio signals. Combined with a precisely calibrated R2R resistor network, it effectively reduces nonlinear distortion and noise, significantly improving dynamic range. The device features a low-power design, is compatible with various digital audio interfaces, and is suitable for scenarios such as high-definition music playback, professional recording, and high-end audio systems. It provides users with transparent and natural audio reproduction, making it one of the core components for high-fidelity signal conversion in high-end audio equipment.
[0003] However, in existing technologies, audio converters typically have multiple types of interfaces, and most of these interfaces are exposed. This allows dust from the air to enter the interface when it is not in use. Long-term dust accumulation can lead to poor interface wiring, resulting in decreased sound quality, noise, and in severe cases, damage to the interface. Traditional rubber plugs are prone to falling off under impact, thus losing their protection. Furthermore, rubber plugs are small and difficult to find after falling off. In addition, the interfaces are usually protruding and easily damaged during transportation. Therefore, a 64-bit R2R audio digital-to-analog converter is proposed. Utility Model Content
[0004] This utility model addresses the shortcomings of existing technologies by providing the following technical solution:
[0005] A 64-bit R2R audio digital-to-analog converter, comprising:
[0006] The housing has several control knobs on one side wall and a display screen on the side wall. An adjustment assembly is provided on the inside of the housing. A circuit board is provided on the top of the adjustment assembly. Several wiring interfaces are provided on the top of the adjustment assembly.
[0007] The adjustment assembly includes sliding frames, with mounting plates fixedly mounted on the tops of the two sliding frames. Two connecting buckles are located on the top of the mounting plates. A connecting frame is rotatably mounted inside the connecting buckles, and a rotating plate is rotatably mounted at the other end of the connecting frame. Several insertion slots are provided on one side wall of the housing, and two adjustment slots are provided on another side wall of the housing. An adjustment frame is fixed to one side of the mounting plate. A push rod is slidably mounted inside the adjustment frame, and a spring is also provided inside the adjustment frame. Two positioning slots are provided inside one side of the housing. A locking plate is fixed to one end of the push rod, a connecting piece is fixed to one side of the locking plate, and a push piece is fixed to one end of the connecting piece.
[0008] As an improvement to the above technical solution, the adjustment component further includes a slide groove, which is formed on one side wall of the housing. A guide groove is formed on the inner side of the slide groove, and a sliding plate is slidably arranged on the inner side wall of the guide groove.
[0009] As an improvement to the above technical solution, the outer sidewall of the connecting frame is slidably fitted onto the inner sidewall of the adjusting groove, and the connecting end of the wiring interface is detachably abutted against the sidewall of the socket groove.
[0010] As an improvement to the above technical solution, the side wall of the card plate can be detachably slidable inside the positioning groove, and the connecting piece is slidably disposed inside the sliding plate.
[0011] As an improvement to the above technical solution, the side wall of the card plate slides on the side wall of the housing, and the mounting plate slides against the inner side wall of the housing.
[0012] As an improvement to the above technical solution, the connecting piece slides inside the groove, and the rotating plate is rotatably disposed on the side wall of the housing.
[0013] The beneficial effects of this utility model are as follows: When in use, pressing the push plate causes the card plate to disengage from the inner side of the positioning groove, while compressing the spring. Then, pushing the push plate causes the mounting plate to slide out through the sliding frame. At the same time, the rotating plate is unfolded by the cooperation of the connecting buckle on the mounting plate and the connecting frame. While the rotating plate is unfolded, the wiring interface is simultaneously abutted against the socket slot for wiring. When not in use, the above process is reversed to close the rotating plate and retract the wiring interface into the housing, thereby protecting the wiring interface. Attached Figure Description

[0022] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.
[0023] In existing technologies, dust may accumulate inside the device interface, which can lead to poor wiring, reduced sound quality, and noise over time. To address this, a 64-bit R2R audio digital-to-analog converter is proposed.
[0024] To address the above problems, the following implementation method is provided:
[0025] like Figure 1 - Figure 7 As shown, one embodiment of this utility model is provided:
[0026] A 64-bit R2R audio digital-to-analog converter, comprising:
[0027] The housing 1 has several control knobs 2 on one side wall and a display screen 3 on the side wall. The inner side of the housing 1 has an adjustment component 4. The top of the adjustment component 4 has a circuit board 5 and several wiring interfaces 6.
[0028] The adjustment assembly 4 includes a sliding frame 401. A mounting plate 402 is fixedly installed on the top of the two sliding frames 401. Two connecting buckles 403 are installed on the top of the mounting plate 402. A connecting frame 404 is rotatably installed on the inner side of the connecting buckle 403. A rotating plate 405 is rotatably installed on the other end of the connecting frame 404. Several insertion slots 406 are opened on one side wall of the housing 1. Two adjustment slots 407 are opened on one side wall of the housing 1. An adjustment frame 408 is fixed on one side of the mounting plate 402. A push rod 409 is slidably installed on the inner side of the adjustment frame 408. A spring 410 is also installed on the inner side of the adjustment frame 408. Two positioning slots 411 are opened on the inner side of one side of the housing 1. A locking plate 412 is fixed on one end of the push rod 409. A connecting piece 414 is fixed on one side of the locking plate 412. A push piece 415 is fixed on one end of the connecting piece 414.
[0029] In the above embodiment, when installation and use are required, pressing the push plate 415 causes the connecting plate 414 to press down the locking plate 412, thereby causing the locking plate 412 to disengage from the positioning groove 411. When the locking plate 412 is pressed down, the push rod 409 connected to the locking plate 412 also compresses the spring 410. At this time, the locking plate 412 is no longer restricted by the positioning groove 411, so the push plate 415 can be pushed to drive the sliding plate 413 to slide in the guide groove 417. At the same time, the adjusting frame 408 and the mounting plate 402 connected to the adjusting frame 408 carry the circuit board 5 and the wiring interface 6 to slide on the sliding frame 401. Meanwhile, the connecting buckle 403 set on the mounting plate 402 pushes the connecting frame 404 to slide in the adjusting groove 407 and finally pushes open the rotating plate 405. At the same time, the wiring interface 6 also abuts against the socket groove 406. At this time, it can be used normally. When not in use, the wiring interface 6 is retracted by reversing the unfolding operation so that it is not exposed on the outside.
[0030] Reference Figure 3 - Figure 7 The adjustment component 4 also includes a slide groove 416, which is formed on one side wall of the housing 1. A guide groove 417 is formed on the inner side of the slide groove 416, and a sliding plate 413 is slidably arranged on the inner side wall of the guide groove 417.
[0031] In the above embodiment, during use, pushing the pusher 415 causes the connecting piece 414 to slide in the slide groove 416, and causes the sliding plate 413 to slide in the guide groove 417.
[0032] Reference Figure 3 - Figure 7The outer sidewall of the connecting bracket 404 slides against the inner sidewall of the adjusting groove 407, and the connecting end of the wiring interface 6 is detachably abutted against the sidewall of the socket groove 406.
[0033] In the above embodiment, when the rotating plate 405 is unfolded, the connecting frame 404 moves within the adjusting groove 407 to drive the rotating plate 405 to unfold. At the same time as the unfolding is completed, the wiring interface 6 also abuts against the socket groove 406.
[0034] Reference Figure 3 - Figure 7 The side wall of the card plate 412 is detachably slidable inside the positioning groove 411, and the connecting piece 414 is slidably disposed inside the sliding plate 413.
[0035] In the above embodiment, the cooperation between the card plate and the positioning groove ensures that the device remains fixed when unfolding and retracting. At the same time, when the push plate is pressed down and the connecting plate is driven to push the card plate out of the positioning groove, the mutual sliding of the connecting plate and the sliding plate ensures that the sliding plate is not affected.
[0036] Reference Figure 3 - Figure 7 The side wall of the card plate slides against the side wall of the housing, and the mounting plate slides against the inner side wall of the housing.
[0037] In the above embodiment, during the unfolding and retraction of the device, the card plate is pressed against the inside of the housing by a spring. When the card reaches the positioning groove, the spring automatically pushes the push rod to drive the card plate into the positioning groove.
[0038] Reference Figure 3 - Figure 7 The connecting piece slides inside the groove, and the rotating plate is rotated and set on the side wall of the housing.
[0039] In the above embodiments, the cooperation of the connecting piece and the sliding groove enables the device to unfold smoothly while limiting the unfolding range. When the device is retracted, the connecting frame drives the rotating plate to automatically retract and stick tightly to the shell.
[0040] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it. Any person skilled in the art can modify or change the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or changes made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
