Description
Technical Field
[0001] This utility model relates to the field of power amplifier equipment technology, and in particular to a professional power amplifier with display screen and DSP processing. Background Technology
[0002] As the core of an audio system, the power amplifier plays a crucial role in the audio field. It amplifies weak, low-power audio signals, providing sufficient power to the speakers so that they can produce loud and clear sound. Whether it is a large concert venue where a power amplifier drives professional speakers to cover the entire audience, or a home where you play music or watch movies, the power amplifier is indispensable. With the development of audio technology, people's requirements for sound quality are constantly rising, which has become a powerful driving force for the continuous innovation of power amplifiers.
[0003] A professional power amplifier with DSP processing and a display screen is a result of advancements in audio technology. It uses a DSP chip to precisely process digital audio signals and adjust parameters such as frequency and phase. The power amplifier circuit then further amplifies the processed signal. In use, the audio input devices and speakers are connected in an orderly manner, and various parameters can be easily set through the display screen. The audio processed by the DSP is amplified and output by the power circuit, thereby driving the speakers to produce high-quality sound.
[0004] In existing technologies, power amplifiers are often affected by vibrations in scenarios such as stage performances and equipment handling. Vibrations generated by the operation of stage lighting equipment and actors' movements, as well as shaking during handling, can cause internal components of the power amplifier to loosen and solder joints to fall off, resulting in unstable audio signal transmission, deterioration of sound quality, damage to the power amplifier structure, reduced stability and reliability, and shortened service life. To address these issues, a professional power amplifier with a display screen and DSP processing is proposed. Utility Model Content

After use, the operation is reversed to secure the plate. This effectively protects all components on the front panel of the amplifier, preventing damage from external forces, extending the equipment's lifespan, and maintaining a clean appearance when the equipment is not in use, thus comprehensively improving the equipment's protective performance.

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0036] Reference Figure 1 , Figure 5 and Figure 6 The present invention provides an embodiment of a professional power amplifier with a display screen and DSP processing, including a power amplifier housing 1. The power amplifier housing 1 can effectively protect the internal electronic components. A groove is opened at the bottom of the power amplifier housing 1. A buffer box 2 is slidably connected in the bottom groove of the power amplifier housing 1. The buffer box 2 is used to accommodate a buffer and shock absorption mechanism. The buffer and shock absorption mechanism is fixedly connected inside the buffer box 2. A panel protection mechanism is rotatably connected to the outside of the power amplifier housing 1.
[0037] The damping mechanism includes a transmission plate 3, which can transmit the vibration received by the power amplifier housing 1 to the vertical damping component and the horizontal damping component. The top of the transmission plate 3 is fixedly connected to the top of the bottom groove of the power amplifier housing 1, the bottom of the transmission plate 3 is fixedly connected to the vertical damping component, and the bottom of the power amplifier housing 1 is fixedly connected to the horizontal damping component.
[0038] The lateral damping assembly includes a damping tube 11. The damping tube 11, through its internal damping fluid, generates resistance against the sliding damping rod 9, converting the lateral vibration kinetic energy experienced by the power amplifier into heat energy. This serves to buffer vibration, stabilize the structure, and protect internal components. The damping rod 9 is slidably connected to both ends of the damping tube 11. When the power amplifier experiences lateral vibration, the rod slides within the damping tube 11, working in conjunction with the damping fluid and damping spring 10 inside the tube 11 to convert the vibration kinetic energy into heat energy, effectively buffering lateral vibration, stabilizing the power amplifier structure, and improving audio quality. The end of the damping rod 9 furthest from the damping tube 11... A damping head 8 is fixedly connected, and the damping head 8 connects the damping rod 9 and the transmission link 7. When the power amplifier is subjected to lateral vibration, the vibration is transmitted through the transmission link 7, causing the damping rod 9 to slide inside the damping tube 11. The damping tube 11 and the damping spring 10 work together to buffer the lateral vibration, ensuring the stability of the power amplifier structure and the quality of audio output. The damping spring 10 is sleeved on the outside of the damping rod 9. When the power amplifier is subjected to lateral vibration and the damping rod 9 slides inside the damping tube 11, it generates elastic deformation, absorbs and buffers the vibration energy, and assists the damping tube 11 and the damping rod 9 in stabilizing the power amplifier structure and reducing vibration interference.
[0039] One end of the damping spring 10 is fixedly connected to the outside of the damping tube 11, and the other end of the damping spring 10 is fixedly connected to the outside of the damping head 8.
[0040] The bottom of the transmission plate 3 is rotatably connected to the transmission link 7. The function of the transmission link 7 is to transmit the lateral vibration received by the transmission plate 3 to the damping head 8, thereby driving the damping rod 9 to move in the damping tube 11, realizing the transmission and buffering of lateral vibration. The end of the transmission link 7 away from the transmission plate 3 is rotatably connected to the inside of the damping head 8.
[0041] The vertical vibration damping assembly includes a damping slide rod 4, which transmits the vertical vibration of the power amplifier and converts it into the elastic potential energy of the damping spring 6, effectively reducing the impact of vertical vibration on the power amplifier. The top of the damping slide rod 4 is fixedly connected to the bottom of the conduction plate 3, and the bottom of the buffer box 2 is fixedly connected to the damping tube 5, which provides a sliding track for the damping slide rod 4. In cooperation with the damping slide rod 4 and the damping spring 6, the vertical vibration of the power amplifier is buffered, ensuring the stable operation of the power amplifier. The outer side of the damping slide rod 4 is slidably connected to the inner side of the damping tube 5, and the bottom of the damping slide rod 4 is fixedly connected to the damping spring 6. The damping spring 6 absorbs and converts the energy of the vertical vibration of the power amplifier through its own compression and extension, playing a damping and buffering role, protecting the power amplifier components from damage by vertical vibration. The outer side of the damping spring 6 is fixedly connected to the inner side of the damping tube 5.
[0042] Reference Figure 1 and Figure 2A parameter display screen 15 is fixedly connected to the inside of the amplifier housing 1. The parameter display screen 15 can clearly display various parameters of the amplifier, such as volume, tone, frequency, etc. By connecting to the internal DSP processing module, relevant audio processing information is acquired and displayed in real time. An audio connector 16 is fixedly connected to the inside of the amplifier housing 1. The audio connector 16 is used to connect different audio devices, such as microphones, speakers, and players. Different types of interfaces have different characteristics and applicable ranges, meeting diverse audio input and output needs. An adjustment knob 17 is fixedly connected to the inside of the amplifier housing 1. The adjustment knob 17 is used to adjust various parameters of the amplifier, such as volume and pitch. The surface of the adjustment knob 17 is designed with anti-slip textures for easy user operation. Audio parameters can be precisely adjusted by rotating the knob. A heat dissipation hole 18 is provided on the top of the amplifier housing 1 to ensure air circulation inside the amplifier, dissipate heat generated by internal electronic components, prevent damage due to overheating, and improve the stability and reliability of the amplifier. A connecting slide plate 19 is fixedly connected to the outside of the amplifier housing 1. The connecting slide plate 19 has a guide rail structure and is used to cooperate with the connection components of other devices to realize the splicing or fixing of multiple amplifier devices, facilitating combined use in large audio systems.
[0043] Reference Figures 1 to 3 The panel protection mechanism includes a first protection plate 12, which has a certain degree of transparency and wear resistance and can rotate around a pivot to cover and protect the front panel of the amplifier housing 1. The outer side of the first protection plate 12 is rotatably connected to the inner side of the amplifier housing 1. A hinge 13 is fixedly connected to the outer side of the first protection plate 12, allowing the first protection plate 12 and the second protection plate 14 to rotate relative to each other, making it convenient to adjust the coverage area of the protection plate. The second protection plate 14 is fixedly connected to the outer side of the hinge 13, which is used to cooperate with the locking slide rod 21 to fix the protection plate and also plays the role of covering and protecting the front panel of the amplifier housing 1. The outer side of the second protection plate 14 has a locking hole.
[0044] The inner side of the power amplifier housing 1 is slidably connected to a locking rod 20. The locking rod 20 can connect and fix or unlock and separate the protection board 14 through its own locking and releasing, which facilitates the installation, disassembly and adjustment of the components and enhances the flexibility and operability of the structure. The inner side of the locking rod 20 is fixedly connected to a locking slide rod 21. The locking slide rod 21 flexibly positions and locks the components, which enhances the stability and operability of the equipment structure. The outer side of the locking slide rod 21 is slidably connected to the inner side of the power amplifier housing 1 and the outer side of the locking slide rod 21 is slidably connected to the inner side of the locking hole of the protection board 14.
[0045] A return spring 22 is sleeved on the outer side of the locking slide rod 21. The return spring 22 provides a reverse force after the locking lever 20 and other components are activated by its own elastic deformation, so that it returns to the initial position, ensuring the stable and repeatable operation of the component connection and separation function. One end of the return spring 22 is fixedly connected to the outer side of the locking lever 20, and the other end of the return spring 22 is fixedly connected to the inner side of the power amplifier housing 1.
[0046] Working principle: When the power amplifier is needed, pull the locking lever 20 outward. The locking lever 20 drives the locking slide 21 to slide outward against the elastic force of the return spring 22, so that the locking slide 21 disengages from the locking hole of the second protection plate 14. Then, the second protection plate 14 is rotated outward. The second protection plate 14 rotates around the first protection plate 12 with the hinge 13. At the same time, the first protection plate 12 rotates around the pivot, exposing the parameter display screen 15, audio connector 16 and adjustment knob 17 on the front panel of the power amplifier housing 1.
[0047] During use, if the power amplifier is subjected to vertical vibration, the vibration is transmitted to the damping slide rod 4 through the conduction plate 3. The damping slide rod 4 slides in the damping tube 5 and compresses the damping spring 6. The damping spring 6 absorbs and converts the vibration energy. If it is subjected to lateral vibration, the conduction plate 3 transmits the vibration to the damping head 8 through the transmission link 7, which drives the damping rod 9 to slide in the damping tube 11. The damping rod 9 interacts with the damping fluid and damping spring 10 in the damping tube 11 to convert the vibration kinetic energy into heat energy, thereby buffering the lateral vibration.
[0048] After use, first rotate the protection plate 12 and protection plate 24 back to their original positions to cover the front panel of the power amplifier shell 1. Then push the locking lever 20 so that the locking slide rod 21 slides into the locking hole of the protection plate 24. Under the action of the return spring 22, the locking lever 20 and the locking slide rod 21 return to their initial positions, thus completing the fixing of the protection plate.
[0049] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
