Description

Technical Field

[0001] The utility model relates to the technical field of aerospace, in particular to a foldable aviation noise-canceling headphone. Background Art

[0002] In a broad sense, during use, the angle of the arc-shaped rod can be flexibly adjusted to ensure the comfort of aviation workers. At the same time, the built-in electronic noise-canceling system of the headphone can also reduce the huge noise during takeoff and landing of the aircraft. In addition, the air pressure inside and outside the earplug can be adjusted to relieve the pressure difference between the inside and outside of the ear, eliminating ear pain or discomfort. The headphone with a foldable headrest includes a headrest and a headphone bracket connecting two headphones. Mounting seats rotatably connected to the headphones are respectively provided on the outer sides of the two headrests. Adjusting members capable of adjusting the length of the headband are respectively provided at both ends of the headrest. The adjusting members are rotatably connected to the mounting seats. When worn, the headrest is opened, and the arc-shaped rod can be greatly expanded to reduce the tight feeling of the user. In addition, when packaged, the headrest can be folded, which can reduce the size of the packaging box and make it more convenient to carry.

[0003] After retrieval, the text of the publication number "CN212486744U" mentions that "the utility model discloses a noise-canceling headphone module and a headphone that are easy to assemble, including a combined frame and a microphone module, a speaker module, and a cover installed on the combined frame; the combined frame is provided with a first installation cavity, a second installation cavity, and a sound guide channel that communicate with each other. The microphone module and the speaker module are respectively installed in the first installation cavity and the second installation cavity. The cover is covered outside the second installation cavity, and a cavity is formed between the cover and the speaker module. The sound guide channel communicates with the cavity.", when in use, it realizes an integrated modular structure of the microphone and the speaker, makes the positioning of the microphone and the speaker accurate, and the noise-canceling performance of the headphone is more stable. Its overall assembly is simple, reducing the assembly process, improving the assembly efficiency and the noise-canceling effect. However, for the stability, anti-deformation and pressure resistance of the product specification size of conventional aviation headphones, a fixed headrest is selected. The adjustment dimension of the fixed arc-shaped rod is small, and the wearing pressure restraint of the worker is large. Wearing in one dimension for a long time continuously will cause a tight head and great pressure, resulting in dull pain, and at the same time, it will also cause a certain sense of compression on the ear part, affecting the hearing system.
