Description

Technical Field

[0001] This utility model relates to the field of media player technology, and in particular to a dual-backup audio player. Background Technology

[0002] In the field of audio playback, especially in professional scenarios such as performances where playback stability is extremely important, the reliability and sound quality reproduction capabilities of audio systems have always been key objectives.

[0003] Existing audio players have the following shortcomings:

[0004] 1. Existing audio playback control technology may not have a dual backup mechanism, or although there is a backup, the switching process is not stable or fast enough. When the main system fails, it cannot switch to the backup system in a timely and seamless manner, resulting in audio playback interruption or abnormalities.

[0005] 2. In the face of emergencies such as hardware failures, software errors, and network problems, existing technologies lack effective countermeasures, which can easily lead to the loss or damage of audio data, affecting the integrity and accuracy of audio playback.

[0006] 3. In the face of compatibility issues with different playback devices, normal playback may not be possible. When processing audio signals from different sources or decoding complex audio formats, there may be limitations in decoding capabilities and loss of details, resulting in degraded sound quality.

[0007] Therefore, existing problems need to be improved in order to solve the above-mentioned issues. Utility Model Content

[0030] The following is in conjunction with the appendix Figure 1-5 The specific embodiments of this utility model will be further described in detail to make the technical solution of this utility model easier to understand and master.

[0031] In this embodiment, it should be understood that the terms "middle", "upper", "lower", "top", "right side", "end", "front", "back", "center", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0032] Furthermore, unless otherwise specified in this specific embodiment, the connection or fixing method between components can be achieved by bolt fixing, pin fixing, or pin connection commonly used in the prior art. Therefore, it will not be described in detail in this embodiment.

[0033] like Figures 1-5 As shown, a dual-backup audio player includes:

[0034] The housing 1 is equipped with a control panel 2 and a signal interface panel 3. The control panel 2 is tilted to better fit the user's usage habits and improve the user experience.

[0035] The DDCS (Double Digital Control System) dual backup synchronous control system is located inside the housing 1. The DDCS dual backup synchronous control system includes an audio signal control module, an audio signal processing module, and a double control switch. The audio signal control module is connected to the signal interface panel 3, the audio signal processing module is connected to the audio control module and the signal interface panel 3, and the double control switch is connected to the control panel 2 and the audio signal control module.

[0036] The audio signal control module includes a first control module and a second control module. When the control panel 2 is operated, the dual control switch synchronously touches the first control module and the second control module to achieve synchronous operation of the first control module and the second control module.

[0037] The linkage can be of two types. One type uses a physical linkage mechanical structure (such as a dual potentiometer or a linkage button group). When the user uses the active knob 21, stop button 22, pause button 23, and play button 24, the mechanical device simultaneously and equally drives the corresponding sensors or switch contacts connected to the first and second control modules. The other type uses an electronic switch array and signal replication circuit. The user's operation of a single control (such as the active knob 21, stop button 22, pause button 23, and play button 24) generates a single electrical signal. This signal is replicated in real time by the signal replication circuit inside the dual control switch to generate two identical independent control signals, which are sent to the corresponding control ports of the first and second control modules respectively. This method also ensures the immediacy and precise synchronization of the operation.

[0038] Whether using mechanical or electronic methods, the design of the dual-control switch ensures that with a single user operation, both systems respond synchronously immediately.

[0039] The dual-backup synchronous control module is compatible with various audio devices and formats, featuring plug-and-play drivers for automatic, seamless switching. Even when the main system encounters hardware failures, software errors, or network anomalies, it ensures stable audio output, greatly reducing the risk of interruption. Audio operation response is extremely fast; whether switching audio, adjusting volume, or adding effects, everything is completed instantly without noticeable delay. In scenarios with extremely high real-time requirements, such as live performances, it guarantees perfect audio presentation.

[0040] The signal interface panel 3 includes a signal input interface 31 and a signal output interface 32. The input end of the audio signal processing module is connected to the signal input interface 31 and the audio signal control module, and the output end of the audio signal processing module is connected to the signal output interface 32.

[0041] The control panel 2 includes a rotary knob 21, a stop button 22, a pause button 23, and a play button 24. Each button controls the first control module and the second control module simultaneously via a dual-control switch.

[0042] The signal input interface 31 is provided with two interfaces, and the signal input interface 31 is a Type-C interface. The two input interfaces correspond to the first control module and the second control module, respectively.

[0043] The system has four signal output interfaces 32, all of which are XLR connectors. Two of these interfaces correspond to the first control module, and the other two correspond to the second control module. Two sets of two signal output interfaces form a group of independent stereo outputs, allowing for hot backup of the audio source.

[0044] The XLR connector is a three-pin XLR connector. The three-pin XLR connector has the following advantages:

[0045] 1. By connecting its three pins to ground, hot (positive) and cold (negative) terminals respectively, the audio signal is split into two signals with opposite phases for transmission. At the receiving end, these two signals are superimposed. Since external interference affects both signals equally during transmission, the interference signals cancel each other out during superposition, greatly reducing the impact of external interference on the audio signal and ensuring high-quality signal transmission.

[0046] 2. Compared to unbalanced transmission methods (such as two-pin plugs), the balanced transmission method of the three-pin XLR interface has stronger anti-interference capabilities. Because unbalanced transmission shares the signal and ground wires, external interference can easily affect signal transmission. In contrast, the balanced transmission of the XLR interface divides the signal into positive and negative paths for independent transmission and has independent grounding, which can better resist external electromagnetic interference and ensure the purity of the audio signal.

[0047] 3. The three-pin XLR connector is firmly and reliably connected, and is not easy to loosen or fall off, so as to ensure the stability of signal transmission in various usage scenarios for audio equipment that needs to be moved and plugged in frequently.

[0048] The audio signal processing module includes a dual-channel USB-C audio interface and an audio digital conversion chip, which is a DUAC (Digital USBS Audio Conversion Technology) chip; it supports ordinary lossless audio output PCM encoding 32Bit / 384KHz, and also supports DSD encoded audio. The decoder 64 / 128 (DOP) truly restores lossless stereo sound.

[0049] Therefore, compared with the prior art, this application has the following advantages:

[0050] 1. With dual independent control modules, audio playback can be switched seamlessly and without interruption when the main control system encounters hardware failures or software errors, greatly reducing the risk of performance interruption and meeting the stringent requirements of professional-grade systems.

[0051] 2. Dual-control switch design (mechanical linkage or electronic synchronization) ensures that the user's operation of a single control physically triggers the response of both systems simultaneously, eliminating the operation delay difference between the two systems and ensuring the absolute synchronization of operations such as play, pause, stop, and volume adjustment.

[0052] 3. Plug-and-play drivers are compatible with mainstream operating systems and audio workstations; adopting a high-performance DUAC audio digital conversion chip, it supports high-specification PCM (32Bit / 384KHz) and DSD64 / 128 (DOP) decoding, combined with a balanced transmission XLR output interface, effectively suppressing interference and truly restoring lossless stereo sound quality.

[0053] 4. Dual Type-C input interfaces support simultaneous connection of two computers or audio source devices; four XLR output interfaces (two stereo sets) support independent output or redundant output of main and backup channels, providing flexible on-site wiring solutions.

[0054] 5. Even the shared audio signal processing module significantly improves the system's ability to resist single points of failure through dual-channel independent processing, fault-tolerant design, and redundancy protection, combined with DDCS's fast switching capability.

[0055] A control method for an audio player, applied to a dual-backup audio controller, includes:

[0056] S1. Receive user operation commands for individual controls via a double-pole control switch;

[0057] S2. Two independent control signals are generated synchronously by the dual-pole control switch and sent to the first control module and the second control module respectively.

[0058] S3, the first control module and the second control module send synchronous control commands to the connected playback device or control software to achieve complete synchronization of playback, pause, stop or volume adjustment operations of the dual system.

[0059] The main technical effects of this utility model are reflected in the following aspects:

[0060] This dual-backup audio player is compatible with a variety of audio devices and formats, features plug-and-play drivers, and ensures stable audio output even when the main system encounters hardware failures, software errors, or network anomalies.

[0061] Of course, the above are just typical examples of this utility model. In addition, this utility model may have many other specific implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by this utility model.
