Description

Technical Field

[0001] The present invention relates to the technical field of audio, and particularly to a directional audio with a noise reduction component. Background Art

[0002] In the continuous evolution of audio technology, directional audio has demonstrated extensive application value in various fields such as conferences, performances, and home entertainment due to its unique audio directional propagation ability. The core of the directional sound wave control technology lies in its unique algorithm design. By precisely calculating the propagation path and diffusion angle of the sound beam, this technology can concentrate the sound energy in a specific direction to achieve directional propagation of sound. The realization of this technology relies on complex mathematical models and algorithm support; in practical applications, the directional sound wave control technology will dynamically adjust the shape and direction of the sound beam according to factors such as the placement position of the speaker and environmental noise to ensure that the sound can accurately reach the target area while minimizing the diffusion of sound in other areas; its core purpose is to achieve directional propagation and enhancement of sound by precisely controlling the propagation direction and shape of the sound wave.

[0003] However, with the continuous improvement of the performance of directional audio, the complexity of its internal mechanical components has also increased significantly, which directly leads to increasingly serious vibration and noise problems during the operation of the audio. Traditional noise reduction methods for directional audio mainly rely on passive noise reduction materials such as sound insulation foam and shock pads. Although these materials can suppress the propagation of noise to a certain extent, their noise reduction effect is insufficient when facing high-load operating conditions, and the noise problem remains prominent, seriously affecting the user's auditory experience.

[0004] In addition, due to the large number of electrical components inside the directional audio, a large amount of heat will be generated during its long-term and continuous operation. If these heats cannot be dissipated in a timely and effective manner, it will inevitably lead to an increase in the internal temperature of the audio, which will seriously threaten its performance stability and service life. Traditional heat dissipation methods, such as natural wind heat dissipation, although can relieve the heat dissipation pressure to a certain extent, its heat dissipation efficiency is low and cannot meet the dual requirements of modern directional audio for high-efficiency heat dissipation and low-noise environment. Especially when used under high-load operation or in a closed space, the limitations of natural wind heat dissipation are particularly obvious, often resulting in overheating of the audio, which in turn affects its normal operation. In view of the above problems, this invention document proposes a directional audio with a noise reduction component. Summary of the Invention

[0016] Compared with the prior art, the present invention provides a directional sound with a noise reduction component, and has the following beneficial effects: 1. The directional speaker with a noise reduction component, by setting an active structure, a first noise reduction structure, and a conversion structure. When the directional speaker body starts to play audio, the vibration of its internal mechanical components is inevitable. To effectively reduce and absorb the noise generated by these vibrations, this directional speaker introduces an active structure, the core of which is a movable plate that can move up and down. As the vibration of the speaker is transmitted, the movable plate moves up and down accordingly. This dynamic process not only directly acts on the first noise reduction structure, squeezing or stretching it through physical contact to absorb part of the vibration energy. At the same time, the movement of the movable plate also triggers the linkage mechanism of the conversion structure. Since the diameter of the second gear is larger than that of the first gear, according to the principle of gear transmission, the moving distance is effectively amplified, and the movement range of the second toothed plate is expanded, enabling it to more significantly adjust the position or state of the second noise reduction structure, thereby achieving a more extensive absorption and buffering of the noise generated by the vibration of the movable plate and the directional speaker body, further enhancing the noise reduction efficiency of this directional speaker.

[0017] 2. The directional speaker with a noise reduction component, by setting a heat dissipation structure and an air guiding structure. During the operation of the speaker, the vibration of the directional speaker body not only drives the movable plate of the noise reduction component to vibrate up and down inside the installation cabinet, but also through a precise gear transmission mechanism, that is, the diameter of the second gear is larger than that of the first gear, achieving an amplification effect of the movement distance, making the moving distance of the second toothed plate significantly exceed the direct moving distance of the movable plate. Furthermore, through the linkage effect of the vertical plate, it prompts the adjusting plate to perform a rapid and effective displacement inside the installation cabinet, thereby promoting the change of air flow inside the installation cabinet. To effectively manage the heat generated by the operation of the directional speaker body, the heat dissipation structure is carefully designed to include an S-shaped first heat dissipation pipe and a second heat dissipation pipe. These heat dissipation pipes are made of high-efficiency heat conduction materials and are designed to quickly absorb and disperse the heat generated by the directional speaker body. At the same time, the air guiding structure consists of a first air guiding pipe and a second air guiding pipe, which are cleverly embedded inside the installation cabinet to form a closed-loop air circulation system. As the adjusting plate moves, the air flow inside the installation cabinet is guided to the first air guiding pipe and the second air guiding pipe, and then the air is directed to the first heat dissipation pipe and the second heat dissipation pipe. During this process, the air not only provides the necessary convective heat transfer conditions for the heat dissipation pipes, but also accelerates the heat dissipation through the flow inside the pipes, thereby effectively reducing the operating temperature of the directional speaker body, ensuring that the speaker can maintain within a safe temperature range even during long-term high-load operation, guaranteeing the stable operation and long-term durability of the speaker, and providing users with an excellent auditory experience and equipment reliability.

[0018] 3. The directional sound speaker with a noise reduction component, by providing a protective cover which is arranged on the outer wall of the installation cabinet and fixedly connected to the bottom of the directional sound speaker body and the top of the connecting plate, can comprehensively block external rainwater, making it difficult for external rainwater and foreign objects to enter the interior of the installation cabinet, providing a certain protection effect for the first gear, the second gear, the first toothed plate and the second toothed plate, and further ensuring the service life of the directional sound speaker.

[0031] Working principle: When the directional speaker body 2 is working, it will generate vibrations, causing the movable plate 301 to move up and down inside the installation cabinet 101. The movable plate 301 squeezes or pulls the first telescopic rod 401 and the first spring 402. At the same time, when the movable plate 301 drives the first toothed plate 604 to move, under the action of the rotating shaft 601, the first toothed plate 604 drives the second toothed plate 605 to move up or down through the first gear 602 and the second gear 603. Since the diameter of the second gear 603 is larger than that of the first gear 602, the moving distance of the second toothed plate 605 is greater than that of the first toothed plate 604, so that the adjustment range of the adjustment plate 501 by the second toothed plate 605 becomes larger, enabling the second spring 503 to play a further buffering and shock-absorbing role for the movable plate 301 and the directional speaker body 2, thereby achieving the effect of noise reduction. Since the directional speaker body 2 is working, it drives the movable plate 301 to vibrate up and down inside the installation cabinet 101. And because the diameter of the second gear 603 is larger than that of the first gear 602, the moving distance of the second toothed plate 605 is greater than that of the movable plate 301, causing the second toothed plate 605 to drive the adjustment plate 501 to quickly move inside the installation cabinet 101 through the vertical plate 504. Thus, when the air inside the installation cabinet 101 changes, it can adjust the air inside the first heat dissipation pipe 701 and the second heat dissipation pipe 702 through the first air duct 801 and the second air duct 802, enabling it to flow quickly, thereby playing an auxiliary heat dissipation role for the directional speaker body 2.
