Firstly, a negative pressure value of the first chamber and the second chamber is generated by the vacuum generator. A standard close-type speaker is placed within the third chamber, and the first chamber and the third chamber are in communication with each other. An under-test close-type speaker is placed within a fourth chamber, and the second chamber and the fourth chamber are in communication with each other. A pressure difference value between the third chamber and the fourth chamber is measured by the differential pressure gauge. If the pressure difference value is larger than a predetermined value, the under-test close-type speaker has the leak. Consequently, the misjudgment is reduced, and the testing efficiency is enhanced."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Close-type speaker leak test system and method","description":"A close-type speaker leak test system includes a first chamber, a second chamber, a third chamber, a fourth chamber, a vacuum generator, and a differential pressure gauge.
