Elimination of speaker structure

This creation department is about improving the structure of a speaker, especially a kind of speaker structure improvement and innovation that can achieve excellent sound-absorbing effect, prevent noise damage to the surrounding environment, and increase the practical and effective characteristics in its overall implementation. Designer.

According to many mechanical and electrical equipments or in the process of producing various products, the factory often produces a lot of waste gas and waste heat, so that the exhaust gas and waste heat can be discharged to the outside, usually in the mechanical equipment or plant. The exhaust pipe is connected to allow the exhaust gas and waste heat to escape from the exhaust pipe; however, because the mechanical device is in operation or during the production process of the factory, a great noise is generated, causing noise. With the discharge of such exhaust gas and waste heat, and the outward conduction through the exhaust pipe, the surrounding environment will be greatly jeopardized by noise, and therefore, some manufacturers have developed various types of speaker and the exhaust pipe. The connection is such that the exhaust gas and the waste heat can be silenced through the exhaust pipe while being discharged through the exhaust pipe, thereby greatly reducing the noise hazard generated.

Among them, in the early days, the sound-absorbing cotton is generally disposed inside the speaker to block the sound transmission by the sound-absorbing cotton; however, after the long-term use, the sound-absorbing cotton may be wet and hardened, resulting in The sound absorption effect is worse.

Therefore, the manufacturer has developed a "sound speaker structure" No. M333591 as disclosed on June 1, 2008 to reduce the generation of aerodynamic noise, which includes: a box body containing a An opening portion and a second opening portion, wherein the first opening portion and the second opening portion are respectively disposed at two ends of the box body and penetrate each other for circulating a fluid, and an effective width of the first opening portion a depth smaller than a depth of the box, the ratio of the effective width to the depth of the box is 1:2 to 1:5; a plurality of sound absorbing elements, each of the sound absorbing elements being disposed on the inner surface of the box, the plurality of The sound absorbing members are horizontally arranged with each other; and a connecting portion is disposed at the second opening portion of the box to connect the box body and a tube body; wherein the flow system enters the box from the first opening portion The body is outputted from the second opening to be delivered to the tubular body via the connecting portion.

However, although the above-mentioned speaker structure can achieve the expected effect of muffling through the exhaust gas and waste heat, it is also found in its actual operation and implementation that the structure is only arranged in the cabinet body by horizontally arranging a plurality of muffling elements horizontally. Therefore, the airflow is still easily passed through the passage formed between the sound absorbing members, so that the sound absorbing effect is still limited, so that the airflow still generates noise after passing through the speaker, so that the overall structural design still has improvement. space.
