Description

Technical Field

[0001] The utility model relates to the field of earphones, in particular to an earphone shell sound absorption structure. Background Art

[0002] Traditional headphone shells are usually made of hard materials, such as plastic or metal. These materials have poor sound absorption and isolation effects, mainly because their acoustic properties are not ideal. During the propagation of sound waves, the acoustic impedance of hard materials is high, which limits the absorption and propagation of sound. At the same time, the structure of hard materials is simple and there is no complex acoustic structure to control the propagation of sound, which makes the sound easily reflected and superimposed during the propagation process, thus affecting the sound quality.

[0003] To solve these problems, modern headphone designs usually adopt more advanced acoustic designs and material selections. For example, the headphone shells are made of softer and more sound-absorbing materials, such as memory foam and silicone. These materials have good sound-absorbing effects and can effectively absorb and isolate external noise, reducing the impact of noise on sound quality.

[0004] However, there may be limitations in using only a single headphone material to solve the problems of sound quality and sound absorption and noise reduction. Although the use of softer materials with better sound absorption effects such as memory foam and silicone can effectively absorb and isolate external noise and reduce the impact of noise on sound quality, this single method may still have insufficient sound quality consistency. Different materials may have different absorption and isolation effects on sounds of different frequencies. If only one material is used, it may be difficult to achieve balanced absorption and isolation of sounds of all frequencies, resulting in insufficient consistency in sound quality. This may cause the sound of certain frequency bands to be too prominent or insufficient, affecting the listening experience. Utility Model Content
