Description

Technical Field

[0001] The utility model relates to the technical field of automobile production and testing equipment, in particular to a box door control device. Background Art

[0002] Electronic products require performance testing before leaving the factory, including acoustic performance testing. This is especially true for consumer electronics such as mobile phones, computers, and headphones, where acoustic performance is a crucial component of product quality. Acoustic performance testing must be conducted in a soundproof enclosure. For a long time, acoustic testing has primarily focused on the mid- and high-frequency range, necessitating the development of a series of acoustically shielded enclosures with excellent sound insulation. However, as product quality and performance requirements increase, so too do the demands for low-frequency performance. This is especially true after long-term use, when the mid- and high-frequency harmonic components caused by low frequencies become more pronounced, leading to a significant decline in sound quality and listening experience. This new demand and new challenges pose challenges to consumer electronics. A typical requirement is how to design and produce a soundproof enclosure that effectively eliminates low-frequency noise to meet testing requirements.

[0003] The soundproof boxes in the existing technology all use microphones with extremely high sensitivity. When the locking mechanism opens and closes the door quickly, a sharp pressure difference will be generated instantly, generating a strong airflow to impact the microphone, thereby affecting the test results.
