Description

Technical Field

[0001] The utility model relates to the field of speakers, and particularly to a wave-curved and evenly constant sound system manager. Background Art

[0002] Traditional passive linear array speakers usually rely on an external power amplifier cabinet to provide the necessary power and control. These power amplifier cabinets have various functions to improve sound quality, protect the speakers, and optimize performance. The main functions include: power amplification, signal processing, frequency division function, network connection and control, temperature and overload protection, delay and correction. For traditional passive linear array speakers, the array beam control ability of such power amplifier cabinets is limited, mainly due to the following factors:

[0003] 1. Passive design: Since passive speakers rely on an external power amplifier for driving, they do not contain any electronic processing functions to directly control the shape and direction of the beam.

[0004] 2. Control limitations: The external power amplifier can perform some basic signal processing, but for beamforming and pointing control, these processes are usually not sufficient to finely control the propagation direction of sound. Beam control mainly relies on the physical arrangement and angle adjustment of the speakers.

[0005] 3. No DSP integration: Compared with active arrays, passive arrays usually do not integrate a digital signal processor (DSP), which is a key technology for complex beam control. The DSP in an active system can adjust the output of each speaker unit in real time to form a specific beam pattern.

[0006] In summary, it can be seen that the traditional passive linear array system is not as flexible and efficient as the modern active linear array system in terms of beam control. In practical applications, engineers need to adjust the physical position and angle of the speakers to achieve the required sound field coverage, rather than electronically controlling the beam direction.

[0007] Therefore, it is necessary to improve the existing passive linear array speakers to enable them to have beam control ability and achieve efficient management of the speaker system. Summary of the Utility Model

[0030] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the following further details the present utility model with reference to embodiments. However, the scope of protection required by the present utility model is not limited to the specific embodiments below.

[0031] As Figure 1 shown, the wave-curved and evenly balanced audio system manager includes a speaker main body 1 and independently designed DSP processor 5, first power amplifier 6, power supply manager 7, signal source pre - processing module 8 and second power amplifier 9, where:

[0032] The DSP processor 5, first power amplifier 6, power supply manager 7, signal source pre - processing module 8 and second power amplifier 9 are arranged in sequence and installed in the speaker main body 1 in a transverse insertion manner.

[0033] Figure 2 Figure [ID number] is a rear view of the present utility model, showing one surface, Figure 3 Figure [ID number] only shows the exploded view of the power supply manager 7. Among them, the DSP processor 5, first power amplifier 6, power supply manager 7, signal source pre - processing module 8 and second power amplifier 9 are all encapsulated into a rectangular structure and installed in the speaker main body 1 in a penetrating and inserted manner like the power supply manager 7.

[0034] Here, the signal source pre - processing module, DSP processor module, power amplifier, power supply manager module, etc. are independently designed and encapsulated, and each module is connected through a standardized interface, which is convenient for later maintenance and upgrade.

[0035] The power manager 7 supplies power to the DSP processor 5, the first power amplifier 6, the signal source pre - processing module 7, and the first power amplifier 9 respectively. The power manager is a 1U - width power manager. The power manager 7 is designed with a linkage interface with the signal source pre - processing module 7 to ensure the automated management of the system power supply. It ensures that the system can start safely when the power is turned on and can be turned on safely when the power is interrupted.

[0036] The signal source pre - processing module 8 is used to perform gain adjustment and equalization pre - processing on digital - analog signals to obtain pre - processed signals. The signal source pre - processing module is provided with analog (XLR) and digital (Dante / AES 67) interfaces, supporting multiple audio signal inputs, including XLR, Dante / AES 67, etc. The signal source pre - processing module 8 is also provided with an RJ45 network interface for providing network data exchange, and is equipped with two power plugs, one for power input and the other for powering extended devices.

Through Ethernet or Wi - Fi connection, users can remotely monitor and control the system, including DSP parameter adjustment, power amplifier setting, system status monitoring, power switch, etc.

[0038] The DSP processor is a 1U - width DSP processor. The DSP processor is used to perform beam control, frequency division, filtering, delay, and phase adjustment processing on the pre - processed signal to obtain a finely - processed signal.

[0040] In this embodiment, the DSP processor uses an integrated high - performance DSP chip and implements beam control of sound using existing advanced algorithms. In this embodiment, the model of the DSP chip is: ADI21489, and the existing algorithm used is: the algorithm with variable beam coverage angle and constant frequency response (the algorithm with variable beam coverage angle and constant frequency response aims to design an array system that can adjust the coverage angle of the beam while maintaining a constant frequency response. This usually requires the array to have flexible beam - forming capabilities and be able to control the direction and width of the beam by adjusting the phase and / or frequency of each element in the array).

[0041] The first power amplifier and the second power amplifier are used to amplify the finely - processed signal to obtain an amplified signal and output it to the passive linear array speaker.

Here, the power amplifiers are efficient class-D amplifiers, ensuring low distortion and high power output, and supporting parallel driving of multiple speakers. Adopting an efficient power amplifier design can provide strong and stable output power to ensure the normal operation of passive speakers. In this embodiment, the model of the amplifier used is BCBT500 / 16P.

[0043] The first power amplifier and the second power amplifier are provided with 2 8-channel balanced signal input sockets for connecting to the DSP processor; and 1 37-core output socket for connecting to the array speaker.

[0044] Specifically, hanging members 3 are provided on both the left and right sides of the cabinet body 1. Each hanging member is configured with a bolt 2. Handles 4 are provided on both sides of the cabinet body for facilitating the handling of the cabinet.

[0047] When the network switch is turned on, the power processor 5 automatically starts the signal source pre-stage processing module 8 to prepare for subsequent audio processing;

[0048] Then, the digital-to-analog signal source is input to the signal source pre-stage processing module 8. This module is responsible for the pre-processing of the signal, including gain adjustment and equalization, and sends the processed signal to the DSP processor 5;

[0049] The signal is processed by advanced algorithms in the DSP processor 5 to achieve beam control, frequency division, filtering, delay, and phase adjustment. The processed signal will be output to two power amplifiers;
