Description

Technical Field

[0001] This utility model relates to the field of seat headrest technology, and in particular to a car seat music headrest structure. Background Technology

[0002] With societal progress, rising living standards, and advancements in automotive technology, automobiles have evolved from mere modes of transportation into mobile spaces integrating travel, entertainment, and leisure. The iterative demands of in-vehicle acoustic systems have driven this transformation from transportation tools to "third living spaces," leading to upgrades from mono amplification to surround sound. While traditional door panel / center console layouts can meet basic needs, they suffer from technical bottlenecks such as uneven sound field distribution (front sound pressure levels are generally 30% higher than rear) and significant high-frequency attenuation (exceeding 6dB / oct). Especially with the widespread adoption of new energy vehicles, the noise spectrum of electric motors differs significantly from that of traditional engines, making it difficult for existing layouts to achieve optimal adaptation to Active Noise Cancellation (ANC) technology.

[0003] Currently, existing automotive seat headrest technology often features complex structures. These complex structures may include multiple speaker units, intricate wiring layouts, and mechanical structures for fixing and adjusting the speaker positions. This complexity not only increases production costs but may also negatively impact the comfort and safety of the seat. Utility Model Content
